技术领域technical field
本申请涉及终端中屏下指纹采集技术，尤其涉及一种控制方法、终端及计算机存储介质。The present application relates to a fingerprint collection technology under the screen in a terminal, and in particular, to a control method, a terminal and a computer storage medium.
背景技术Background technique
目前，很多终端在显示屏的下方区域设置有指纹模组，用于采集用户的指纹，以解锁终端的锁屏界面。At present, many terminals are provided with a fingerprint module in the lower area of the display screen, which is used to collect the user's fingerprint to unlock the lock screen interface of the terminal.
以显示屏为有机发光二极管(OLED，Organic Light-Emitting Diode)屏幕为例来说，终端在采集指纹时，OLED屏幕处于高亮模式(HBM，High Brightness Mode)，但是，处于HBM模式的OLED屏幕并不是一直都处于点亮状态，而是在每一个帧周期内有一个亮度跌落，这样，在采集指纹的过程中若遇到显示屏的亮度跌落，那么，在采集到的指纹图像上会出现一个黑色的横条纹，从而影响指纹模组的性能，增大了指纹模组的拒识率(FRR，FalseRejection Rate)。Taking the display screen as an organic light-emitting diode (OLED, Organic Light-Emitting Diode) screen as an example, when the terminal collects fingerprints, the OLED screen is in high brightness mode (HBM, High Brightness Mode), but the OLED screen in HBM mode It is not always on, but there is a brightness drop in each frame period. In this way, if the brightness of the display screen drops during the process of collecting fingerprints, it will appear on the collected fingerprint image. A black horizontal stripe affects the performance of the fingerprint module and increases the rejection rate (FRR, False Rejection Rate) of the fingerprint module.

具体实施方式Detailed ways
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.
实施例一Example 1
本申请实施例提供了一种控制方法，该方法应用于一终端中。The embodiment of the present application provides a control method, and the method is applied in a terminal.
图1为传统的驱动OLED屏幕的结构示意图，如图1所示，OLED屏幕可以包括显示区、扫描驱动器1、扫描驱动器2和多分信号输出选择器，显示区两侧的扫描驱动器1和扫描驱动器2用来提供显示区像素的复位补偿信号Scan和开关信号EM，复位补偿信号Scan用来完成每个帧周期内的像素刷新操作，开关信号EM用来打开和关断像素，例如，扫描驱动器1通过信号Scan(1)、EM(1)、Scan(3)…EM(K-1)和Scan(K-1)驱动显示区，扫描驱动器2通过信号Scan(2)、EM(2)、Scan(4)…EM(K)和Scan(K)驱动显示区，多分信号输出选择器和处理器之间相连接，将处理器发出的要显示的图片的像素数据信号分配到显示区内的每一列上。通过这种方式，可以实现OLED屏幕的显示功能。FIG. 1 is a schematic structural diagram of a traditional driving OLED screen. As shown in FIG. 1, the OLED screen may include a display area, a scan driver 1, a scan driver 2 and a multi-signal output selector, and a scan driver 1 and a scan driver on both sides of the display area. 2 is used to provide the reset compensation signal Scan and the switch signal EM of the pixels in the display area. The reset compensation signal Scan is used to complete the pixel refresh operation in each frame period, and the switch signal EM is used to turn on and turn off the pixels. For example, the scan driver 1 The display area is driven by the signals Scan(1), EM(1), Scan(3)...EM(K-1) and Scan(K-1), and the scan driver 2 passes the signals Scan(2), EM(2), Scan (4)...EM(K) and Scan(K) drive the display area, the multi-signal output selector and the processor are connected, and the pixel data signal of the picture to be displayed sent by the processor is distributed to each pixel in the display area. on a column. In this way, the display function of the OLED screen can be realized.
图2A为传统的驱动OLED屏幕的时序图，如图2A所示，在每个帧周期T内，由于需要对OLED屏幕进行刷新，所以，每个帧周期都存在关断时间ΔT，在实际应用中，在ΔT内将EM置为高电平，控制屏幕熄灭，屏幕像素复位补偿信号Scan(n)和Scan(n-1)分别被拉到低电平，如此，完成像素的复位、补偿操作，致使屏幕亮度的时序图中会在ΔT内出现亮度跌落；其中，图2A中的Scan(n)、Scan(n-1)和EM(n)仅为一行像素的控制信号时序示意图，其他行的像素控制信号和此一样，仅时序稍有不同，n为大于等于2小于等于K的正整数。Figure 2A is a timing diagram of a traditional driving OLED screen. As shown in Figure 2A, in each frame period T, since the OLED screen needs to be refreshed, there is an off time ΔT in each frame period. In practical applications , set EM to a high level within ΔT, control the screen to turn off, and the screen pixel reset compensation signals Scan(n) and Scan(n-1) are respectively pulled to a low level, thus completing the pixel reset and compensation operations , resulting in a brightness drop within ΔT in the timing diagram of screen brightness; among them, Scan(n), Scan(n-1) and EM(n) in FIG. 2A are only the control signal timing diagram of one row of pixels, and the other rows The pixel control signal of is the same, only the timing is slightly different, n is a positive integer greater than or equal to 2 and less than or equal to K.
也就是说，在屏下光学指纹模组进行指纹采图时，需要把OLED屏幕调节到HBM模式，使屏幕达到最大亮度，以此来提高屏下光学指纹模组接收到的信号量，提升性能，但是OLED屏幕在HBM模式下并不是一直都处于点亮状态的，每个帧周期T内会有一段时间ΔT会处于关断状态，因此，即使是在HBM模式OLED屏幕处于最大亮度条件下，在每个帧周期内OLED屏幕仍然会关断一段时间ΔT，体现在屏幕亮度上为每个帧周期内的一个亮度跌落。That is to say, when the under-screen optical fingerprint module performs fingerprint acquisition, it is necessary to adjust the OLED screen to HBM mode to make the screen reach the maximum brightness, so as to increase the amount of signals received by the under-screen optical fingerprint module and improve performance. , but the OLED screen is not always on in HBM mode, and there will be a period of time ΔT in each frame period T in the off state. Therefore, even when the OLED screen in HBM mode is at the maximum brightness condition, In each frame period, the OLED screen will still be turned off for a period of time ΔT, which is reflected in the screen brightness as a brightness drop in each frame period.
图2B为传统的进行指纹采集的OLED屏幕的排布示意图和指纹图像的排布示意图，如图2B所示，OLED屏幕亮度的周期性跌落会对屏下光学指纹的性能造成不利的影响，由于OLED屏幕是以行扫描的形式驱动的，也即屏幕内的每一行像素从上到下以一个固定的时间间隔依次点亮与关断，从而每个帧周期内屏幕的关断时间ΔT就体现为一条在屏幕上不断从上到下扫动的黑色横条，黑色横条的宽度和帧周期内的黑帧宽度ΔT有关，ΔT越大，黑色横条的宽度越大。如果屏下光学指纹模组在进行曝光采集指纹信息的时候，这个黑色横条扫过屏下指纹识别区域的话，就会造成屏下光学指纹模组传感器阵列的个别像素行上的信号量要整体弱于其他像素行，从而在最终采集到的指纹图像上体现为一个黑色的横条纹，影响屏下光学指纹模组的性能，增大模组的拒识率。FIG. 2B is a schematic diagram of the arrangement of a traditional OLED screen for fingerprint collection and a schematic diagram of the arrangement of fingerprint images. As shown in FIG. 2B, the periodic drop in the brightness of the OLED screen will adversely affect the performance of the optical fingerprint under the screen. The OLED screen is driven in the form of line scanning, that is, each line of pixels in the screen is turned on and off at a fixed time interval from top to bottom, so that the off time ΔT of the screen in each frame period is reflected in It is a black bar that continuously sweeps from top to bottom on the screen. The width of the black bar is related to the black frame width ΔT in the frame period. The larger the ΔT, the greater the width of the black bar. If the under-screen optical fingerprint module is exposing and collecting fingerprint information, the black bar sweeps across the under-screen fingerprint recognition area, which will cause the signal volume on individual pixel rows of the under-screen optical fingerprint module sensor array to be the overall It is weaker than other pixel rows, so it is reflected as a black horizontal stripe on the finally collected fingerprint image, which affects the performance of the optical fingerprint module under the screen and increases the rejection rate of the module.
为了避免指纹采集中刷新屏幕对指纹图像的影响，本申请实施例提出一种控制方法，图3为本申请实施例提供的一种可选的控制方法的流程示意图，参考图3所示，上述控制方法可以包括：In order to avoid the influence of refreshing the screen on the fingerprint image during fingerprint collection, an embodiment of the present application proposes a control method. FIG. 3 is a schematic flowchart of an optional control method provided by an embodiment of the present application. Referring to FIG. 3 , the above Control methods can include:
S301：当终端的显示屏处于点亮状态且接收到来自终端的指纹模组采集到的指纹信息时，生成第一控制指令；S301: When the display screen of the terminal is in a lit state and the fingerprint information collected by the fingerprint module of the terminal is received, generate a first control instruction;
具体来说，为了实现指纹解锁，终端在显示屏的下方区域上设置一个指纹识别区域，首先，用于需要点亮显示屏，点亮后，在锁屏界面上显示有指纹识别区域，如图2B中位于手机的显示屏下方区域的屏下指纹识别区域，用户使用预先输入的指纹对应的手指长按屏下指纹识别区域，此时，终端的显示屏处于点亮状态且接收到来自指纹模组采集到的指纹信息，终端得知此时开始进行指纹解锁。Specifically, in order to realize fingerprint unlocking, the terminal sets a fingerprint identification area on the lower area of the display screen. First, it is used to light up the display screen. After lighting, the fingerprint identification area is displayed on the lock screen interface, as shown in the figure. In 2B, the fingerprint recognition area under the screen is located in the area below the display screen of the mobile phone. The user uses the finger corresponding to the pre-input fingerprint to long press the fingerprint recognition area under the screen. The fingerprint information collected by the group, the terminal knows that the fingerprint unlocking starts at this time.
为了避免指纹采集中刷新屏幕对指纹图像的影响，终端生成第一控制指令，通过第一控制指令实现对终端的显示屏的控制。In order to avoid the influence of refreshing the screen on the fingerprint image during fingerprint collection, the terminal generates a first control instruction, and the display screen of the terminal is controlled through the first control instruction.
S302：根据第一控制指令，将显示屏的状态从刷新状态切换至非刷新状态；S302: According to the first control instruction, switch the state of the display screen from a refreshed state to a non-refreshed state;
其中，刷新状态为显示屏处于点亮状态时每隔预设时间段熄灭显示屏以刷新显示屏上的图像的状态，非刷新状态为显示屏处于点亮状态时维持点亮显示屏以持续显示显示屏上的图像的状态。Among them, the refresh state is the state in which the display screen is turned off every preset time period to refresh the image on the display screen when the display screen is on Status of the image on the display.
这里，终端通过生成的控制指令，切换显示屏的状态，由于在正常状态下，显示屏均处于刷新状态，也就是说，显示屏每隔预设时间段自动进行图像的扫描刷新，例如，预设时间段可以为帧周期T；为了防止扫描刷新对指纹采集的影响，将显示屏在正常状态下的刷新状态切换至非刷新状态，即，在指纹采集的过程中，停止对显示屏上的图像进行扫描刷新，如此，来提高采集到的指纹图像的图像质量。Here, the terminal switches the state of the display screen through the generated control command, because in the normal state, the display screen is in the refresh state, that is to say, the display screen automatically scans and refreshes the image every preset time period. The time period can be set as the frame period T; in order to prevent the influence of scanning and refresh on fingerprint collection, the refresh state of the display screen in the normal state is switched to the non-refresh state, that is, during the process of fingerprint collection, stop the The image is scanned and refreshed, so as to improve the image quality of the collected fingerprint image.
为了不影响对显示屏上图像的扫描刷新，在一种可选的实施例中，在S302之后，上述方法可以包括：In order not to affect the scanning and refreshing of the image on the display screen, in an optional embodiment, after S302, the above method may include:
当接收完成来自终端的指纹模组采集到的指纹信息时，生成第二控制指令；When receiving the fingerprint information collected by the fingerprint module from the terminal, a second control instruction is generated;
根据第二控制指令，将显示屏的状态从非刷新状态切换至刷新状态。According to the second control instruction, the state of the display screen is switched from the non-refresh state to the refresh state.
具体来说，在完成对指纹图像的采集之后，为了正常的对显示屏上的图像进行扫描刷新，需要在完成对指纹图像的采集之后，将显示屏的状态切换回正常的刷新状态，以实现正常的对显示屏上的图像的扫描刷新。Specifically, after the fingerprint image collection is completed, in order to scan and refresh the image on the display screen normally, it is necessary to switch the display screen state back to the normal refresh state after the fingerprint image collection is completed. Normal scan refresh of the image on the display.
为了实现将显示屏的状态从刷新状态切换为非刷新状态，在一种可选的实施例中，当终端包括第一驱动器和第二驱动器，且第一驱动器和第二驱动器分别连接至显示屏；相应地，S302可以包括：In order to switch the state of the display screen from the refreshed state to the non-refreshed state, in an optional embodiment, when the terminal includes a first driver and a second driver, and the first driver and the second driver are respectively connected to the display screen ; Correspondingly, S302 may include:
根据第一控制指令，通过控制第一驱动器中用于驱动显示屏的驱动信号和第二驱动器中用于驱动显示屏的驱动信号，将显示屏的状态从刷新状态切换至非刷新状态。According to the first control instruction, the state of the display screen is switched from the refreshed state to the non-refreshed state by controlling the driving signal in the first driver for driving the display screen and the driving signal in the second driver for driving the display screen.
这里，显示屏分别与第一驱动器和第二驱动器连接，第一驱动器和第二驱动器分别通过驱动信号驱动显示屏，来实现将显示屏的状态从刷新状态切换为非刷新状态。Here, the display screen is connected to the first driver and the second driver respectively, and the first driver and the second driver respectively drive the display screen through driving signals, so as to switch the state of the display screen from the refreshed state to the non-refreshed state.
其中，驱动信号包括：用于是否复位补偿显示屏的信号和用于是否持续点亮显示屏的信号。Wherein, the driving signal includes: a signal for resetting and compensating the display screen and a signal for whether to continuously light the display screen.
也就是说，驱动信号分为两种，一种是用于是否复位补偿显示屏的信号，可以用Scan来表示，另一种是用于是否持续点亮显示屏的信号，可以用EM来表示。That is to say, the driving signal is divided into two types, one is the signal used to reset and compensate the display screen, which can be represented by Scan, and the other is the signal used to continuously light the display screen, which can be represented by EM .
举例来说，若第一驱动器的驱动信号包括Scan(1)和EM(1)，第二驱动器的驱动信号包括Scan(2)和EM(2)，当显示屏处于刷新状态时，EM(1)和EM(2)在每个帧周期T内的ΔT内为高电平，Scan(1)在前半个ΔT内为低电平，Scan(2)在后半个ΔT内为低电平，为了避免屏幕亮度跌落，终端通过控制第一驱动器和第二驱动器，将EM(1)和EM(2)均置位低电平，将Scan(1)和Scan(2)均置位高电平，这样，将显示屏的状态从刷新状态切换至非刷新状态，从而防止屏幕亮度跌落。For example, if the driving signals of the first driver include Scan(1) and EM(1), and the driving signals of the second driver include Scan(2) and EM(2), when the display screen is in the refresh state, EM(1) ) and EM(2) are high in ΔT in each frame period T, Scan(1) is low in the first half of ΔT, Scan(2) is low in the second half of ΔT, In order to avoid the drop of screen brightness, the terminal controls the first driver and the second driver to set both EM(1) and EM(2) to a low level, and set both Scan(1) and Scan(2) to a high level , in this way, the state of the display screen is switched from the refresh state to the non-refresh state, thereby preventing the screen brightness from dropping.
进一步地，为了不影响对显示屏上图像的扫描刷新，在一种可选的实施例中，根据第二控制指令，将显示屏的状态从非刷新状态切换至刷新状态，包括：Further, in order not to affect the scanning and refreshing of the image on the display screen, in an optional embodiment, according to the second control instruction, the state of the display screen is switched from the non-refreshing state to the refreshing state, including:
根据第二控制指令，分别通过控制第一驱动器中用于驱动显示屏的驱动信号和第二驱动器中用于驱动显示屏的驱动信号，将显示屏的状态从非刷新状态切换至刷新状态。According to the second control instruction, the state of the display screen is switched from the non-refresh state to the refresh state by controlling the driving signal in the first driver for driving the display screen and the driving signal in the second driver for driving the display screen respectively.
同样地，为了将显示屏的状态切换回刷新状态，还是通过第一驱动器的驱动信号和第二驱动器的驱动信号实现对显示屏在每个帧周期内的扫描刷新，即切换回正常状态。Similarly, in order to switch the state of the display screen back to the refresh state, the driving signal of the first driver and the driving signal of the second driver are used to implement scanning and refreshing of the display screen in each frame period, that is, switching back to the normal state.
举例来说，对处于非刷新状态的显示器来说，终端的第一驱动器和第二驱动器，将EM(1)和EM(2)均置位低电平，将Scan(1)和Scan(2)均置位高电平，为了切换回刷新状态，需要通过第一驱动器和第二驱动器将各自的驱动信号切换回正常状态，即在每个帧周期内的ΔT内EM(1)和EM(2)均置位高电平，Scan(1)在前半个ΔT内为高电平，Scan(2)在后半个ΔT内为高电平。For example, for a display in a non-refreshing state, the first driver and the second driver of the terminal set both EM(1) and EM(2) to a low level, and scan(1) and Scan(2) ) are set to high level, in order to switch back to the refresh state, it is necessary to switch the respective drive signals back to the normal state through the first driver and the second driver, that is, within ΔT of each frame period EM(1) and EM( 2) Both are set to high level, Scan(1) is high level in the first half ΔT, Scan(2) is high level in the second half ΔT.
这样，将显示屏的状态从非刷新状态切换至刷新状态，以实现对显示屏在每个帧周期T内的刷新。In this way, the state of the display screen is switched from the non-refresh state to the refresh state, so as to realize the refresh of the display screen in each frame period T.
为了将显示屏的状态从刷新状态切换至非刷新状态，在一种可选的实施例中，当终端包括第一控制器和第二控制器，且第一控制器连接至第一驱动器，第二控制器连接至第二驱动器；In order to switch the state of the display screen from the refreshed state to the non-refreshed state, in an optional embodiment, when the terminal includes a first controller and a second controller, and the first controller is connected to the first driver, the first two controllers are connected to the second drive;
相应地，S302可以包括：Correspondingly, S302 may include:
根据第一控制指令，通过第一控制器控制第一驱动器中用于驱动显示屏的驱动信号，且通过第二控制器控制第二驱动器中用于驱动显示屏的驱动信号，将显示屏的状态从刷新状态切换至非刷新状态。According to the first control instruction, the first controller controls the driving signal used for driving the display screen in the first driver, and the second controller controls the driving signal used for driving the display screen in the second driver, and the state of the display screen is controlled by the second controller. Switch from refreshed to non-refreshed state.
也就是说，在处理器与第一驱动器之间设置有第一控制器，在处理器与第二驱动器之间设置有第二控制器，进一步地，通过处理器生成的第一控制指令分别去控制第一控制器和第二控制器，使得第一控制器控制第一驱动器的驱动信号，第二控制器控制第二驱动器的驱动信号。That is to say, a first controller is arranged between the processor and the first driver, and a second controller is arranged between the processor and the second driver. Further, the first control instructions generated by the processor are respectively The first controller and the second controller are controlled so that the first controller controls the driving signal of the first driver, and the second controller controls the driving signal of the second driver.
举例来说，还是以第一驱动器的驱动信号包括Scan(1)和EM(1)，第二驱动器的驱动信号包括Scan(2)和EM(2)为例来说，当开始指纹采集时，终端的处理器生成第一控制指令，通过第一控制指令控制第一控制器和第二控制器，第一控制器控制第一驱动器的驱动信号，第二控制器控制第二驱动器的驱动信号，第一控制器将EM(1)和EM(2)均置位低电平，第二控制器将Scan(1)和Scan(2)均置位高电平，这样，将显示屏的状态从刷新状态切换至非刷新状态，从而防止屏幕亮度跌落。For example, taking the driving signal of the first driver including Scan(1) and EM(1), and the driving signal of the second driver including Scan(2) and EM(2), when fingerprint collection starts, The processor of the terminal generates a first control instruction, controls the first controller and the second controller through the first control instruction, the first controller controls the driving signal of the first driver, and the second controller controls the driving signal of the second driver, The first controller sets both EM(1) and EM(2) to a low level, and the second controller sets both Scan(1) and Scan(2) to a high level, so that the state of the display screen is changed from The refresh state is switched to the non-refresh state, which prevents the screen brightness from dropping.
为了将显示屏的状态切换回刷新状态，在一种可选的实施例中，根据第二控制指令，将显示屏的状态从非刷新状态切换至刷新状态，包括：In order to switch the state of the display screen back to the refresh state, in an optional embodiment, according to the second control instruction, switching the state of the display screen from the non-refresh state to the refresh state includes:
根据第二控制指令，通过第一控制器控制第一驱动器中用于驱动显示屏的驱动信号，且通过第二控制器控制第二驱动器中用于驱动显示屏的驱动信号，将显示屏的状态从非刷新状态切换至刷新状态。According to the second control instruction, the first controller controls the driving signal used to drive the display screen in the first driver, and the second controller controls the driving signal used to drive the display screen in the second driver, and the state of the display screen is controlled by the second controller. Switch from non-refresh state to refresh state.
在处理器与第一驱动器之间设置有第一控制器，在处理器与第二驱动器之间设置有第二控制器的基础上，终端可以通过处理器生成的第二控制指令分别去控制第一控制器和第二控制器，使得第一控制器控制第一驱动器的驱动信号，第二控制器控制第二驱动器的驱动信号。A first controller is arranged between the processor and the first driver, and on the basis that a second controller is arranged between the processor and the second driver, the terminal can respectively control the second controller through the second control instruction generated by the processor. A controller and a second controller, so that the first controller controls the driving signal of the first driver, and the second controller controls the driving signal of the second driver.
举例来说，还是以第一驱动器的驱动信号包括Scan(1)和EM(1)，第二驱动器的驱动信号包括Scan(2)和EM(2)为例来说，当完成指纹采集时，终端的处理器生成第二控制指令，通过第二控制指令控制第一控制器和第二控制器，第一控制器控制第一驱动器的驱动信号，第二控制器控制第二驱动器的驱动信号，将各自的驱动信号切换回正常状态，即在每个帧周期内的ΔT内EM(1)和EM(2)均置位高电平，Scan(1)在前半个ΔT内为高电平，Scan(2)在后半个ΔT内为高电平。For example, taking the driving signal of the first driver including Scan(1) and EM(1), and the driving signal of the second driver including Scan(2) and EM(2) as an example, when the fingerprint collection is completed, The processor of the terminal generates a second control instruction, and controls the first controller and the second controller through the second control instruction, the first controller controls the driving signal of the first driver, and the second controller controls the driving signal of the second driver, Switch the respective drive signals back to the normal state, that is, EM(1) and EM(2) are both set to high level within ΔT in each frame period, and Scan(1) is high level within the first half of ΔT, Scan(2) is high for the second half ΔT.
这样，将显示屏的状态从非刷新状态切换至刷新状态，以实现对显示屏在每个帧周期T内的刷新。In this way, the state of the display screen is switched from the non-refresh state to the refresh state, so as to realize the refresh of the display screen in each frame period T.
下面举实例来对上述一个或多个实施例中的控制方法进行说明。The following examples are used to describe the control method in one or more of the above embodiments.
图4为本申请实施例提供的一种可选的OLED屏幕的结构示意图，如图4所示，和传统的OLED屏幕驱动结构相比，本实例采用了HBM控制器1和HBM控制器2来分别控制左右两侧的扫描驱动器1和扫描驱动器2，在屏下光学指纹模组进行指纹图像信息的时候，HBM控制器1和HBM控制器2控制两个扫描驱动器使EM信号始终处于低电平0，从而使OLED屏幕保持常亮状态，同时将所有复位补偿信号Scan都拉到高电平1，不进行复位补偿操作；如此，通过这种方式，避免了在屏下光学指纹模组采集指纹信息的过程中由于屏幕的周期性亮度跌落造成的指纹图像上的横条纹现象。FIG. 4 is a schematic structural diagram of an optional OLED screen provided by an embodiment of the present application. As shown in FIG. 4 , compared with the traditional OLED screen driving structure, this example adopts HBM controller 1 and HBM controller 2 to Control the scanning driver 1 and scanning driver 2 on the left and right sides respectively. When the optical fingerprint module under the screen performs fingerprint image information, the HBM controller 1 and the HBM controller 2 control the two scanning drivers so that the EM signal is always at a low level 0, so as to keep the OLED screen in a normally bright state, and pull all reset compensation signals Scan to a high level 1, and no reset compensation operation is performed; in this way, in this way, it is avoided to collect fingerprints by the optical fingerprint module under the screen. The horizontal stripe phenomenon on the fingerprint image caused by the periodic brightness drop of the screen during the information process.
具体地，当处理器检测到有手指按压到屏下指纹识别区域时，从处理器输出的指纹按压信号FinTou1和FinTou2同时从高电平1变成低电平0，在检测到FinTou1和FinTou2信号的电平变动后，HBM控制器1和HBM控制器2将输出信号AlwOn1和AlwOn2同时从高电平1变成低电平0，控制扫描驱动器1和扫描驱动器2输出恒定为低电平0的EM信号和恒定为高电平1的Scan信号；在处理器检测到屏下光学指纹模组完成指纹信息采集后，将FinTou1和FinTou2信号同时拉回高电平1，HBM控制器1和HBM控制器2在检测到FinTou1和FinTou2的信号变化后，将输出信号AlwOn1和AlwOn2同时变到高电平1，控制扫描驱动器1和扫描驱动器2恢复到正常的控制屏幕亮度周期性跌落的状态；如此，通过这种方式，可以消除掉OLED屏幕HBM模式下时每个帧周期内的黑帧，从而避免其对屏下光学指纹模组性能的影响。Specifically, when the processor detects that a finger is pressed to the fingerprint recognition area under the screen, the fingerprint pressing signals FinTou1 and FinTou2 output from the processor change from high level 1 to low level 0 at the same time, and when the FinTou1 and FinTou2 signals are detected After the level changes, HBM controller 1 and HBM controller 2 change the output signals AlwOn1 and AlwOn2 from high level 1 to low level 0 at the same time, and control scan driver 1 and scan driver 2 to output a constant low level 0 The EM signal and the Scan signal with a constant high level of 1; after the processor detects that the under-screen optical fingerprint module has completed the fingerprint information collection, it pulls the FinTou1 and FinTou2 signals back to high level 1 at the same time, and the HBM controller 1 and HBM control After detecting the signal changes of FinTou1 and FinTou2, the device 2 changes the output signals AlwOn1 and AlwOn2 to high level 1 at the same time, and controls the scan driver 1 and the scan driver 2 to return to the normal state where the screen brightness periodically drops; so, In this way, the black frame in each frame period in the HBM mode of the OLED screen can be eliminated, thereby avoiding its impact on the performance of the optical fingerprint module under the screen.

状态RST：HBM控制器1和HBM控制器2的复位状态；当OLED屏幕复位或者处理器复位后，HBM控制器1和HBM控制器2自动进入状态RST，在HBM控制器1和HBM控制器2处于RST状态时，处理器输出的FinTou1和FinTou2信号为高电平1，HBM控制器1和HBM控制器2的输出AlwOn1和AlwOn2信号为高电平1；随后HBM控制器1和HBM控制器2给内部的寄存器装填初始值之后，自动进入状态IDLE。State RST: The reset state of HBM controller 1 and HBM controller 2; when the OLED screen is reset or the processor is reset, HBM controller 1 and HBM controller 2 automatically enter the state RST, in HBM controller 1 and HBM controller 2 In the RST state, the FinTou1 and FinTou2 signals output by the processor are high level 1, and the output AlwOn1 and AlwOn2 signals of HBM controller 1 and HBM controller 2 are high level 1; then HBM controller 1 and HBM controller 2 After filling the internal register with the initial value, it automatically enters the state IDLE.
状态IDLE：HBM控制器1和HBM控制器2的空闲状态；IDLE为HBM控制器1和HBM控制器2在OLED屏幕处于非指纹识别时的状态，OLED屏幕复位或者处理器复位后控制器会自动进入此状态，在此状态下，HBM控制器1和HBM控制器2会不断检测信号FinTou1和FinTou2的电平，当处理器检测到有手指触碰图2B中的屏下指纹识别区域后，处理器将FinTou1和FinTou2信号拉到低电平0，HBM控制器1和HBM控制器2将输出AlwOn1和AlwOn2信号拉到低电平0，随后跳转到状态ALON；当处理器没有检测到有手指触碰屏下指纹识别区域时，FinTou1和FinTou2信号保持高电平1输出，此时HBM控制器1和HBM控制器2保持输出AlwOn1和AlwOn2信号为高电平1，并保持在此IDLE状态。Status IDLE: The idle state of HBM controller 1 and HBM controller 2; IDLE is the state of HBM controller 1 and HBM controller 2 when the OLED screen is not in fingerprint recognition.

状态ALON：HBM控制器1和HBM控制器2的工作状态；ALON为HBM控制器1和HBM控制器2在处于屏下光学指纹识别时的状态，当HBM控制器1和HBM控制器2检测到处理器输出信号FinTou1和FinTou2从高电平1变到低电平0时，会自动进入此ALON状态，在此状态下，HBM控制器1和HBM控制器2会维持输出信号AlwOn1和AlwOn2为低电平0，从而使扫描驱动器1和扫描驱动器2的输出信号EM始终保持在低电平0，输出信号Scan始终保持在高电平1，在此状态下，HBM控制器1和HBM控制器2也会不断检测处理器输出信号FinTou1和FinTou2的值；当屏下指纹模组完成指纹识别后，处理器将信号FinTou1和FinTou2变为高电平1，在此状态下HBM控制器1和HBM控制器2检测到FinTou1和FinTou2变成高电平1后，会将输出信号AlwOn1和AlwOn2变为高电平1，将扫描驱动器1和扫描驱动器2的输出信号EM和Scan恢复成正常的状态，随后HBM控制器1和HBM控制器2自动跳转到IDLE状态。当屏下指纹模组处于指纹识别的过程中时，处理器维持输出信号FinTou1和FinTou2为低电平0，HBM控制器1和HBM控制器2也维持输出AlwOn1和AlwOn2为低电平0，并保持在此ALON状态。Status ALON: The working status of HBM controller 1 and HBM controller 2; ALON is the status of HBM controller 1 and HBM controller 2 when they are in the off-screen optical fingerprint recognition. When HBM controller 1 and HBM controller 2 detect When the processor output signals FinTou1 and FinTou2 change from high level 1 to low level 0, they will automatically enter this ALON state. In this state, HBM controller 1 and HBM controller 2 will maintain output signals AlwOn1 and AlwOn2 are low. level 0, so that the output signal EM of scan driver 1 and scan driver 2 is always kept at low level 0, and the output signal Scan is always kept at high level 1. In this state, HBM controller 1 and HBM controller 2 It will also continuously detect the values of the processor output signals FinTou1 and FinTou2; when the fingerprint module under the screen completes the fingerprint identification, the processor will turn the signals FinTou1 and FinTou2 to high level 1, in this state HBM controller 1 and HBM control After the device 2 detects that FinTou1 and FinTou2 become high level 1, it will change the output signals AlwOn1 and AlwOn2 to high level 1, and restore the output signals EM and Scan of scan driver 1 and scan driver 2 to the normal state, and then HBM controller 1 and HBM controller 2 automatically jump to the IDLE state. When the fingerprint module under the screen is in the process of fingerprint recognition, the processor maintains the output signals FinTou1 and FinTou2 to be low level 0, and the HBM controller 1 and HBM controller 2 also maintain the output of AlwOn1 and AlwOn2 to be low level 0, and remain in this ALON state.
