具体实施方式Detailed ways
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.
本申请实施例提供的显示控制方法，可以应用于带有显示功能的终端10的如图1所示的应用环境中，终端10还可以是带有触控功能。其中，终端10的显示设备102包括显示控制装置110、显示驱动装置120与显示屏130，显示控制装置110通过显示驱动装置120连接显示屏130。具体地，显示控制装置110与主机104连接进行通信，从主机104获取待显示图像的显示数据，并对显示数据进行解析后存入缓存空间；根据预设时序或显示数据的缓存量确定当前驱动时段；其中，当前驱动时段包括显示时段与触控时段；在当前驱动时段为显示时段时，从缓存空间读取显示数据输出至显示驱动装置120；在当前驱动时段为触控时段时，输出触控扫描指令至显示驱动装置120，接收显示驱动装置120根据触控扫描指令返回的触控数据，对触控数据进行转换处理，并将转换处理后的触控数据发送至主机104。其中，终端10可以但不限于是各种个人计算机、笔记本电脑、智能手机、平板电脑、物联网设备和便携式可穿戴设备，物联网设备可为智能电视与智能车载设备等。便携式可穿戴设备可为智能手表、智能手环、头戴设备等。The display control method provided in the embodiment of the present application may be applied to the application environment shown in FIG. 1 of the terminal 10 with a display function, and the terminal 10 may also have a touch function. The
在一个实施例中，如图2所示，提供一种应用于显示设备102的显示控制装置110的显示控制方法，包括步骤202至步骤210：In one embodiment, as shown in FIG. 2, a display control method applied to the
步骤202：接收主机发送显示数据，并对显示数据进行解析后存入缓存空间。Step 202: Receive display data sent by the host, and store the display data in a cache space after parsing the display data.
其中，终端的主机发送的显示数据为需要在显示设备中进行显示的待显示图像对应的显示数据，待显示图像可以是图片或影像数据。待显示图像由一帧帧的显示数据组成，每一帧显示数据对应为显示屏上的一次完整画面显示。显示数据具体可以是显示屏上的像素点数据，每个像素点数据由红、绿、蓝(RGB)颜色分量组成，每个颜色分量8位共24位二进制信号。显示数据还可包括控制每一帧像素点数据进行显示的时序显示信号。The display data sent by the host of the terminal is the display data corresponding to the to-be-displayed image that needs to be displayed in the display device, and the to-be-displayed image may be a picture or image data. The image to be displayed consists of a frame of display data, and each frame of display data corresponds to a complete screen display on the display screen. The display data may be pixel point data on the display screen, each pixel point data is composed of red, green, and blue (RGB) color components, and each color component has 8 bits and a total of 24-bit binary signals. The display data may also include time-series display signals that control the display of pixel data of each frame.
可以理解，主机发送的显示数据用于显示时是以数据流的形式，显示控制装置先对显示数据进行解码处理，并将解码后的显示数据按行存入缓存空间。缓存空间可以理解为是显示控制装置内部的存储器，也可以是外接的存储装置。另外，对显示数据进行解码处理的方式并不唯一，例如可以是根据DSI时序规范对待显示图像的显示数据进行解码处理，也可以是本领域技术人员认可的其他方式，不做限定。It can be understood that the display data sent by the host is in the form of a data stream when used for display. The display control device first decodes the display data, and stores the decoded display data in the buffer space by line. The cache space can be understood as a memory inside the display control device, or an external storage device. In addition, the manner of decoding the display data is not unique, for example, it may be the decoding processing of the display data of the image to be displayed according to the DSI timing specification, or other manners recognized by those skilled in the art, which are not limited.
步骤204：根据预设时序或显示数据的缓存量确定当前驱动时段。Step 204: Determine the current driving period according to the preset timing or the buffer amount of the display data.
其中，当前驱动时段为显示屏当前对应的驱动方式，可包括显示时段与触控时段。具体地，显示时段可以理解为显示驱动装置接收显示控制装置发送的显示数据，并将显示数据传输至显示屏上进行图像显示的时段。触控时段可以理解为显示驱动装置驱动显示屏进行触控扫描并得到触控数据的时段。The current driving period is the driving mode currently corresponding to the display screen, which may include a display period and a touch period. Specifically, the display period can be understood as the period during which the display driving device receives the display data sent by the display control device, and transmits the display data to the display screen for image display. The touch period can be understood as the period during which the display driving device drives the display screen to perform touch scan and obtain touch data.
进一步地，确定显示屏的当前驱动时段的方式并不唯一，可根据是否有接收到主机发送显示数据来确定。当未接收到主机发送显示数据时，表示显示屏处于黑屏无显示状态，可根据第一预设时序确定当前驱动时段为触控时段。当接收到主机发送显示数据时，可根据第二预设时序或显示数据的缓存量确定当前驱动时段。Further, the manner of determining the current driving period of the display screen is not unique, and may be determined according to whether display data sent by the host is received. When the display data sent by the host is not received, it means that the display screen is in a black screen and no display state, and the current driving period can be determined as the touch period according to the first preset timing sequence. When the display data sent by the host is received, the current driving period can be determined according to the second preset time sequence or the buffer amount of the display data.
其中，如图3所示，第一预设时序表示当持续未接收到主机发送显示数据时，按预设时间间隔确定当前驱动时段为触控时段。如图4所示，第二预设时序与主机发送显示数据的时序相同，包括帧显示数据传输时间与帧间隙。则可以是在第二预设时序对应的帧显示数据传输时间时，确定当前驱动时段为显示时段，在第二预设时序对应的帧间隙时，确定当前驱动时段为触控时段。可以理解，触控时段的时长可根据实际需求设定小于或等于帧间隙长度的值。Wherein, as shown in FIG. 3 , the first preset timing indicates that when the display data sent by the host is not continuously received, the current driving period is determined as the touch period according to the preset time interval. As shown in FIG. 4 , the second preset timing is the same as the timing for sending display data by the host, including frame display data transmission time and frame gap. Then, the current driving period may be determined as the display period when the frame display data transmission time corresponding to the second preset timing is used, and the current driving period may be determined as the touch period during the frame gap corresponding to the second preset timing. It can be understood that the duration of the touch period can be set to a value less than or equal to the length of the frame gap according to actual requirements.
如图5所示，还可以是在一帧显示数据传输时间内，根据显示数据的缓存量确定当前驱动时段。可以理解，显示屏的显示时段与触控时段之间没有重叠。在触控时段内，若显示控制装置有接收到显示数据，无法将显示数据通过显示驱动装置传输至显示屏进行显示，只能暂时先将接收到的显示数据按行存入缓存空间，等到进入显示时段时再进行发送。则显示数据的缓存量为缓存空间中存储的显示数据的行数。因此，可根据缓存空间中存储的显示数据的行数确定当前驱动时段。当缓存空间中可存入的行数足够一个触控时段时，即可将当前驱动时段对应为触控时段；当缓存空间中可存入的行数不够一个触控时段时，当前驱动时段即为显示时段。其中，得到显示数据的缓存量的方式并不唯一，可以是根据写入缓存空间的显示数据的行数与从缓存空间读出的显示数据的行数的差值得到，也可以是根据对缓存空间中存储的显示数据进行计数或编号等方式获得。As shown in FIG. 5 , the current driving period may also be determined according to the buffer amount of the display data within the transmission time of one frame of display data. It can be understood that there is no overlap between the display period of the display screen and the touch period. During the touch time period, if the display control device has received display data, it cannot transmit the display data to the display screen for display through the display drive device. Send when the time period is displayed. Then the cache amount of display data is the number of rows of display data stored in the cache space. Therefore, the current driving period may be determined according to the number of lines of display data stored in the buffer space. When the number of lines that can be stored in the buffer space is enough for one touch period, the current driving period can be corresponding to the touch period; when the number of lines that can be stored in the buffer space is not enough for one touch period, the current driving period is for the display period. The method of obtaining the cache amount of display data is not unique. It can be obtained according to the difference between the number of lines of display data written into the cache space and the number of lines of display data read from the cache space, or it can be obtained according to the difference between the number of lines of display data written into the cache space and the number of lines of display data read from the cache space The display data stored in the space is obtained by counting or numbering.
可以理解，采用在一帧显示数据传输时间内，根据显示数据的缓存量确定当前驱动时段为触控时段的方式，相比帧间隙进行触控扫描的方式具有更高的触控响应速度。It can be understood that the method of determining the current driving period as the touch period according to the buffer amount of the display data within the transmission time of one frame of display data has a higher touch response speed than the method of performing touch scanning between frames.
步骤206：在当前驱动时段为显示时段时，从缓存空间读取显示数据输出至显示驱动装置。Step 206: When the current driving period is the display period, read the display data from the buffer space and output it to the display driving device.
在当前驱动时段为显示时段时，显示控制装置可从缓存空间读按行读取显示数据，并将读取每行显示数据传输至显示驱动装置。显示驱动装置只需将收到的每行显示数据传输至显示屏的source线上。然后再发出每行对应的GIP时序将source线接收到的显示数据刷新至显示屏的对应行实现显示。When the current driving period is the display period, the display control device can read the display data by line from the buffer space, and transmit the read display data of each line to the display driving device. The display driving device only needs to transmit the received display data of each line to the source line of the display screen. Then, the GIP timing sequence corresponding to each line is issued to refresh the display data received by the source line to the corresponding line of the display screen to realize display.
步骤208：在当前驱动时段为触控时段时，输出触控扫描指令至显示驱动装置，接收显示驱动装置根据触控扫描指令返回的触控数据。Step 208 : when the current driving period is the touch period, output a touch scan command to the display driving device, and receive touch data returned by the display driving device according to the touch scan command.
在当前驱动时段为触控时段时，显示控制装置输出触控扫描指令至显示驱动装置。显示驱动装置在接收到触控扫描指令后，驱动显示屏上的触控电容层进行触控感应信号的扫描，采集得到触控数据。显示驱动装置再将采集得到触控数据返回至显示控制装置。When the current driving period is the touch period, the display control device outputs a touch scan command to the display driving device. After receiving the touch scanning instruction, the display driving device drives the touch capacitive layer on the display screen to scan the touch sensing signal, and collects touch data. The display driving device then returns the collected touch data to the display control device.
步骤210：对触控数据进行转换处理，将转换处理后的触控数据发送至主机。Step 210 : Convert the touch data, and send the converted touch data to the host.
显示控制装置在得到触控数据后，需要根据触控数据进行转换得到用户在显示屏上进行触控操作的坐标信息或压力信息等。其中，进行转换的方式并不唯一，可根据显示设备的显示屏的触控原理进行确定。例如，互容式触控方式中，可以是在显示屏的行方向上按行输入触控驱动信号，并采集每一列方向上电容线的感应信号来得到触控数据。而自容式触控方式中，每一像素点即对应为一触摸点，可对应输出感应信号来得到触控数据。After the display control device obtains the touch data, it needs to convert according to the touch data to obtain coordinate information or pressure information of the user's touch operation on the display screen. The conversion method is not unique, and can be determined according to the touch control principle of the display screen of the display device. For example, in the mutual capacitive touch method, the touch driving signal may be input row by row in the row direction of the display screen, and the sensing signal of the capacitive line in each column direction may be collected to obtain the touch data. In the self-capacitive touch method, each pixel corresponds to a touch point, and can output a sensing signal correspondingly to obtain touch data.
进一步地，显示控制装置可根据得到的触控数据中的感应信号与正常无触控时的进行对比，获取有触控的感应信号。再根据有触控的感应信号对应的像素点位置进行转换，得到相对显示屏某一角点对应的坐标信息。根据有触控的感应信号的大小确定压力信息。再将转换处理后的坐标信息与压力信息等发送至主机。Further, the display control device can obtain the sensed signal with touch according to the comparison between the sensed signal in the obtained touch data and the normal without touch. Then, it is converted according to the position of the pixel point corresponding to the sensing signal having the touch to obtain the coordinate information corresponding to a certain corner of the display screen. The pressure information is determined according to the magnitude of the touch sensing signal. Then, the converted coordinate information and pressure information are sent to the host.
上述显示控制方法，通过在显示设备中增加显示控制装置，接收主机发出的显示数据进行解析，然后确定显示与触控的时序后，分别对应输出指令至显示驱动装置，以使显示驱动装置完成对显示屏的显示或触控扫描，在本申请中，显示驱动装置只需按照显示控制方法输出的指令完成驱动，无需控制与数据处理过程，可减少显示驱动装置的内部器件从而达到降低尺寸的目的，最终集成于显示屏时可实现较高的屏占比。In the above display control method, a display control device is added to the display device, the display data sent by the host is received for analysis, and after the timing of display and touch is determined, the corresponding output commands are respectively output to the display driving device, so that the display driving device completes the matching. The display or touch scanning of the display screen, in this application, the display driving device only needs to complete the driving according to the instructions output by the display control method, without the need for control and data processing, which can reduce the internal components of the display driving device to achieve the purpose of reducing the size , which can achieve a higher screen-to-body ratio when it is finally integrated into the display.
在一个实施例中，如图6所示，步骤204的根据显示数据的缓存量确定当前驱动时段，包括步骤302至步骤304：In one embodiment, as shown in FIG. 6 , the determination of the current driving period according to the buffer amount of the display data in step 204 includes steps 302 to 304:
步骤302：当显示数据的缓存量大于或等于预设缓存阈值时，确定当前驱动时段为显示时段。步骤304：当显示数据的缓存量小于预设缓存阈值时，确定当前驱动时段为触控时段。Step 302: When the buffering amount of the display data is greater than or equal to the preset buffering threshold, determine that the current driving period is the display period. Step 304: When the buffer amount of the display data is less than the preset buffer threshold, determine that the current driving period is the touch period.
可以理解，预设缓存阈值为触控时段时长对应缓存空间中可存入的显示数据的行数，可根据触控时段的时长、缓存空间的实际容量以及显示数据存入速率等参数确定，不做限定。进一步地，则需根据实际显示屏中触控时段的时长设计缓存空间的实际容量，以满足进行触控扫描的功能。在本实施例中，将缓存空间的实际容量设计可存入20～60行的显示数据。It can be understood that the preset cache threshold is the number of rows of display data that can be stored in the cache space corresponding to the duration of the touch period, which can be determined according to parameters such as the duration of the touch period, the actual capacity of the cache space, and the rate at which the display data is stored. Do limit. Further, the actual capacity of the buffer space needs to be designed according to the duration of the touch period in the actual display screen, so as to satisfy the function of performing touch scanning. In this embodiment, the actual capacity of the buffer space is designed to store 20 to 60 lines of display data.
当缓存空间中存储的显示数据的行数已超出预设缓存阈值，即代表缓存空间中可存入的行数不够一个触控时段，则确定当前驱动时段为显示时段。当缓存空间中存储的显示数据的行数未超出预设缓存阈值，即代表缓存空间中可存入的行数足够一个触控时段，则确定当前驱动时段为触控时段。When the number of lines of display data stored in the cache space exceeds the preset cache threshold, which means that the number of lines that can be stored in the cache space is not enough for one touch period, the current drive period is determined as the display period. When the number of lines of display data stored in the cache space does not exceed the preset cache threshold, which means that the number of lines that can be stored in the cache space is sufficient for one touch period, the current driving period is determined as the touch period.
在其他实施例中，显示驱动装置还可以是包括多个显示驱动芯片，对显示屏进行分区域驱动显示与触控扫描。以下均以显示驱动装置包括第一显示驱动芯片与第二显示驱动芯片，显示控制装置通过第一显示驱动芯片与第二显示驱动芯片分别对显示屏一半的显示区域进行驱动显示与触控扫描的原理进行解释说明。In other embodiments, the display driving device may further include a plurality of display driving chips to perform sub-regional driving display and touch scanning on the display screen. In the following, it is assumed that the display driving device includes a first display driving chip and a second display driving chip, and the display control device uses the first display driving chip and the second display driving chip to drive display and touch-scan scanning on half of the display area of the display screen respectively. The principle is explained.
在一个实施例中，如图7所示，步骤202中的对显示数据进行解析后存入缓存空间，包括步骤402至步骤404：In one embodiment, as shown in FIG. 7 , the display data in step 202 is parsed and stored in the cache space, including steps 402 to 404:
步骤402：对显示数据按行进行解析，并将解析后的每行显示数据按预设比例进行切分，得到第一显示数据与第二显示数据。Step 402 : parse the display data by line, and divide the parsed display data of each line according to a preset ratio to obtain the first display data and the second display data.
其中，预设比例为对每行数据进行切分时占整行长度的比例，可根据第一显示驱动芯片与第二显示驱动芯片分别对显示屏的显示区域进行驱动的划分比例来确定。例如，在本实施例中，采用第一显示驱动芯片对显示屏的左半边进行驱动，采用第二显示驱动芯片对显示屏的右半边进行驱动时，预设比例为一行数据的一半。即在对显示数据进行解码处理，得到一行行的显示数据后，再将每行显示数据按整行数据长度进行对半切分，前一半行显示数据为第一显示数据，后一半行显示数据为第二显示数据。Wherein, the preset ratio is the ratio of the length of the entire row when the data of each row is divided, and can be determined according to the division ratio of the first display driver chip and the second display driver chip respectively driving the display area of the display screen. For example, in this embodiment, when the first display driver chip is used to drive the left half of the display screen, and the second display driver chip is used to drive the right half of the display screen, the preset ratio is half of one line of data. That is, after decoding the display data to obtain the display data of one line by line, the display data of each line is divided into half according to the data length of the whole line, the display data of the first half of the line is the first display data, and the display data of the second half of the line is The second display data.
步骤404：将第一显示数据存入第一缓存空间，将第二显示数据存入第二缓存空间。将切分得到的每个第一显示数据按行存入第一缓存空间，将切分得到的每个第二显示数据按行存入第二缓存空间。则第一缓存空间中均存储的是用于显示在显示屏左半边的显示数据，第二缓存空间中均存储的是用于显示在显示屏右半边的显示数据。Step 404: Store the first display data in the first cache space, and store the second display data in the second cache space. Each first display data obtained by division is stored in the first buffer space by row, and each second display data obtained by division is stored in the second buffer space by row. Then, the first buffer space stores display data for displaying on the left half of the display screen, and the second buffer space stores display data for displaying on the right half of the display screen.
对应地，在一个实施例中，步骤206的从缓存空间读取显示数据输出至显示驱动装置，包括：从第一缓存空间读取第一显示数据输出至显示驱动装置，并从第二缓存空间读取第二显示数据输出至显示驱动装置。Correspondingly, in one embodiment, the step 206 of reading the display data from the buffer space and outputting it to the display driving device includes: reading the first display data from the first buffer space and outputting it to the display driving device, and reading the first display data from the first buffer space and outputting it to the display driving device; The second display data is read and output to the display driving device.
可以理解，在采用两个显示驱动芯片对显示屏进行分区域驱动显示与触控扫描时，显示屏也同样需要配置分区域的source线以及GIP时序控制。则在当前驱动时段为显示时段时，从第一缓存空间读取第一显示数据输出至第一显示驱动芯片，同时从第二缓存空间读取第二显示数据输出至第二显示驱动芯片。进一步地，第一显示驱动芯片将第一显示数据驱动至左边的source线，第二显示驱动芯片将第二显示数据驱动至右边的source线。然后第一显示驱动芯片发出奇数行对应的GIP时序将左右source线接收到的显示数据刷新至显示屏的奇数行实现显示，第二显示驱动芯片发出偶数行对应的GIP时序将左右source线接收到的显示数据刷新至显示屏的偶数行实现显示。It can be understood that when two display driving chips are used to perform sub-regional driving display and touch scanning on the display screen, the display screen also needs to be configured with sub-regional source lines and GIP timing control. Then, when the current driving period is the display period, the first display data is read from the first buffer space and output to the first display driver chip, while the second display data is read from the second buffer space and output to the second display driver chip. Further, the first display driver chip drives the first display data to the source line on the left, and the second display driver chip drives the second display data to the source line on the right. Then the first display driver chip sends out the GIP sequence corresponding to the odd-numbered lines to refresh the display data received by the left and right source lines to the odd-numbered lines of the display screen to realize display, and the second display driver chip sends out the GIP sequence corresponding to the even-numbered lines to receive the left and right source lines. The display data is refreshed to the even-numbered lines of the display screen for display.
在本实施例中，显示控制装置通过两个显示驱动芯片分区域为显示屏提供显示与触控扫描驱动，有助于电源线与各种驱动信号输出线排布，可进一步降低显示驱动装置的功耗与宽度，从而降低显示屏的非显示区域的高度，提高屏占比。In this embodiment, the display control device provides display and touch scan driving for the display screen through two sub-regions of display driving chips, which is helpful for the arrangement of power lines and various driving signal output lines, which can further reduce the cost of the display driving device. power consumption and width, thereby reducing the height of the non-display area of the display screen and increasing the screen ratio.

In addition, the driving status data may also include the operation records of the display screen and the display driving device, as well as attribute information such as the model. After receiving the driving state data sent by the display driving device, the display control device forwards it to the host.
另外，显示控制装置还可将表征其自身属性与工作状态的控制状态信息同步发送至主机，以供主机对显示设备整体的工作状态进行掌握。In addition, the display control device can also send the control state information representing its own attributes and working state to the host synchronously, so that the host can grasp the working state of the display device as a whole.
在一个实施例中，在步骤202的接收主机发送显示数据，并对显示数据进行解析后存入缓存空间之前，还包括：接收主机发送的配置指令，解析得到主控配置指令与驱动配置指令；根据主控配置指令进行初始化配置，并将驱动配置指令发送至显示驱动装置；其中，驱动配置指令用于对显示驱动装置进行初始化配置。In one embodiment, before the display data is sent by the receiving host in step 202, and the display data is parsed and stored in the cache space, the method further includes: receiving a configuration instruction sent by the host, and analysing to obtain the master control configuration instruction and the driver configuration instruction; The initialization configuration is performed according to the master control configuration instruction, and the driving configuration instruction is sent to the display driving device; wherein, the driving configuration instruction is used for initializing and configuring the display driving device.

The configuration instructions may include display mode and display process related instructions, such as power-on (PowerOn), power-off (PowerOff), display on (DisplayOn), and display off (DisplayOff), and the like. The configuration instructions may also include instructions related to data processing, such as RGB inversion and the like.
显示控制装置可对接收的配置指令进行解析得到主控配置指令与驱动配置指令。其中，主控配置指令可包括显示模式和显示流程相关指令，还可包括与数据处理相关指令。驱动配置指令仅包括显示模式和显示流程相关指令。其中，主控配置指令由显示控制装置在解析得到后自动进行初始化配置。驱动配置指令由显示控制装置在解析得到后发送至显示驱动装置，用于对显示驱动装置进行初始化配置。The display control device can parse the received configuration instruction to obtain the master control configuration instruction and the drive configuration instruction. The master control configuration instructions may include instructions related to display mode and display process, and may also include instructions related to data processing. The driver configuration instructions only include the display mode and display process related instructions. The main control configuration instruction is automatically initialized and configured by the display control device after being parsed and obtained.
