According to the working principle of touch components and the medium for transmitting information, touch components can be divided into four types: resistive type, capacitive induction type, electromagnetic induction type, infrared type and surface acoustic wave type.
本申请实施例中，交互平板相当于一个带整机模块的具有触控功能的显示屏，整机模块是交互平板的内置模块，不包含主控模块，其内部运行着一个低性能的Android系统，整机模块主要实现交互平板的显示处理及触控数据处理功能。整机模块的硬件配置较低，除了配置操作系统和基础的处理软件(例如白板书写软件、批注应用软件)外，不支持安装其它应用软件。交互平板如果需要实现其他功能，需要接入主控模块，通过在主控模块上安装相关应用软件来实现对应的功能，例如需要进行文件的展示，则需要在主控模块上安装相关的展示软件，需要实现视频会议功能，则需要在主控模块上安装视频会议软件，等等。主控模块是交互平板上的一个可插拔(OPS，Open Pluggable Specification)模块，交互平板上运行的应用软件都安装在主控模块上。主控模块运行的可以是Windows、高性能Android等操作系统，例如主控模块可以采用PC模块、高性能Android模块等，其可以理解为一台电脑。In the embodiment of the present application, the interactive tablet is equivalent to a display screen with a whole machine module with touch function. The whole machine module is a built-in module of the interactive tablet, does not include the main control module, and runs a low-performance Android system inside. , the whole machine module mainly realizes the display processing and touch data processing functions of the interactive panel. The hardware configuration of the whole machine module is relatively low, except for configuring the operating system and basic processing software (such as whiteboard writing software, annotation application software), it does not support the installation of other application software. If the interactive tablet needs to realize other functions, it needs to be connected to the main control module, and the corresponding functions can be realized by installing relevant application software on the main control module. For example, if the display of files is required, the relevant display software needs to be installed on the main control module , if you need to realize the video conference function, you need to install the video conference software on the main control module, and so on. The main control module is a pluggable (OPS, Open Pluggable Specification) module on the interactive tablet, and the application software running on the interactive tablet is installed on the main control module. The main control module can run operating systems such as Windows and high-performance Android. For example, the main control module can use a PC module, a high-performance Android module, etc., which can be understood as a computer.
交互平板至少包括Android通道、主机通道和HDMI通道等信号源通道，这些信号源通道用于接收不同的信号源的输入信号，从而交互平板可以在不同的信号源通道之间切换，以呈现不同信号源提供的媒体内容。其中，Android通道为交互平板的整机模块自身的工作通道，用于呈现整机模块的媒体内容。主机通道所接入的信号源为主机模块，从而主机通道用于呈现交互平板的主机模块所输入的媒体数据。HDMI通道用于呈现通过交互平板的HDMI接口所接入的信号源的媒体数据。另外，交互平板处于主机通道或者HDMI通道时，交互平板的显示屏实际上会显示两个系统的画面，一个是Android通道的画面，另一个是主机通道或者HDMI通道的画面，Android通道的画面会存在部分透明区域，从而主机通道或者HDMI通道的画面显示在该透明区域中，从而最后呈现的显示画面是两个通道的显示画面。例如，Android通道的画面是侧边栏，则Android通道的画面除了侧边栏的显示区域外，其它区域全是透明区域，从而主机通道或者HDMI通道的显示画面可以显示在透明区域中，最后给用户呈现的结果就是交互平板显示主机通道或者HDMI通道的画面，并且在该画面上叠加显示有Android通道的侧边栏。具体的，整机模块会预先设定主机通道或者HDMI通道等通道的显示画面的区域大小，从而整机模块在接收到触控组件的触控数据时，会将处于该预先设定的区域内的触摸数据发送到主机通道或者HDMI通道进行响应。The interactive tablet includes at least signal source channels such as Android channel, host channel, and HDMI channel. These signal source channels are used to receive input signals from different signal sources, so that the interactive tablet can switch between different signal source channels to present different signals. The media content provided by the source. Among them, the Android channel is the working channel of the whole machine module of the interactive tablet itself, and is used to present the media content of the whole machine module. The signal source connected to the host channel is the host module, so the host channel is used to present the media data input by the host module of the interactive tablet. The HDMI channel is used to present the media data of the signal source connected through the HDMI interface of the interactive tablet. In addition, when the interactive tablet is in the host channel or HDMI channel, the display screen of the interactive tablet will actually display two system pictures, one is the picture of the Android channel, and the other is the picture of the host channel or HDMI channel, and the picture of the Android channel will be displayed. There is a partially transparent area, so that the picture of the host channel or the HDMI channel is displayed in the transparent area, so that the finally presented display picture is the display picture of the two channels. For example, if the picture of the Android channel is a sidebar, the picture of the Android channel except the display area of the sidebar, other areas are all transparent areas, so that the display picture of the host channel or HDMI channel can be displayed in the transparent area, and finally give The result presented by the user is that the interactive tablet displays the picture of the host channel or the HDMI channel, and superimposes and displays the sidebar of the Android channel on the picture. Specifically, the whole machine module will preset the area size of the display screen of the host channel or HDMI channel, so that when the whole machine module receives the touch data of the touch component, it will be in the preset area. The touch data is sent to the host channel or HDMI channel for response.
更具体的，整机模块包括主控板卡，主控板卡上设置有主控芯片、主控芯片的电源电路等外围电路，还设置有多个用于进行通信的通信接口，多个通信接口均与主控芯片连接。多个通信接口具体包括串行接口、USB接口、HDMI接口、Type-C接口和/或触摸线端口(Touch out端口)等。整机模块通过串行接口与主控模块连接，USB接口、HDMI接口等接口与其它设备或终端进行通信连接，从而接收不同的信号源的输入信号，形成相应的信号源通道。例如，整机模块通过串行接口与主控模块连接，形成主机通道，从而可以接收并呈现主机通道发送的媒体内容，或者通过HDMI接口与外接设备连接，形成HDMI通道，从而呈现外接设备所输入的媒体数据。More specifically, the whole machine module includes a main control board, which is provided with a main control chip, a power supply circuit of the main control chip and other peripheral circuits, and is also provided with a plurality of communication interfaces for communication. The interfaces are all connected with the main control chip. The multiple communication interfaces specifically include a serial interface, a USB interface, an HDMI interface, a Type-C interface, and/or a touch line port (Touch out port), and the like. The whole machine module is connected to the main control module through the serial interface, and the USB interface, HDMI interface and other interfaces are connected to other devices or terminals for communication, so as to receive input signals from different signal sources and form corresponding signal source channels. For example, the whole machine module is connected with the main control module through a serial interface to form a host channel, so that it can receive and present the media content sent by the host channel, or connect with an external device through an HDMI interface to form an HDMI channel, so as to present the input from the external device. media data.
主控芯片具有第一功能单元和第二功能单元一共两个独立的功能单元，第一功能单元安装有Android系统，第二功能单元用于进行交互平板的信号源通道的切换控制。第一功能单元和第二功能单元可以通过运行在同一主控芯片上的不同代码来实现，也可以分别通过两个主控芯片上的不同代码来实现(此时，主控芯片的数量为两个)。The main control chip has two independent functional units, a first functional unit and a second functional unit. The first functional unit is installed with an Android system, and the second functional unit is used for switching control of the signal source channel of the interactive tablet. The first functional unit and the second functional unit can be implemented by different codes running on the same main control chip, or by different codes on the two main control chips respectively (in this case, the number of main control chips is two. indivual).
当交互平板处于不同的信号源通道时，整机模块对触控数据具有不同的处理方式，当交互平板的信号源通道为Android通道时，表示交互平板处于整机模块自身的工作通道，用于呈现整机模块的媒体内容。此时，整机模块接收到触控组件发送的触控数据时，由Android系统进行触控数据的兼容性处理(通过兼容性处理，将不同类型的触摸组件产生的触控数据处理成统一格式的数据，从而Android系统的处理进程可以进行识别和响应)，并进行触控数据的操作响应，执行对应的操作。当交互平板的信号源通道为主机通道时，整机模块接收到触控组件发送的触控数据时，首先由Android系统进行触控数据的兼容性处理，然后Android系统根据预先设定的主机通道的显示画面的区域大小，将在主机通道的显示画面区域内产生的触控数据通过第二功能单元转发到主机通道进行响应。当交互平板的信号源通道为HDMI通道时，整机模块接收到触控组件发送的触控数据时，首先由Android系统进行触控数据的兼容性处理，并进行触控数据的操作响应，执行对应的操作。然后Android系统根据预先设定的HDMI通道的显示画面的区域大小，将在HDMI通道的显示画面区域内产生的触控数据通过第二功能单元转发到触摸线端口(Touch out端口)，由触摸线端口(Touch out端口)的外接设备进行响应。When the interactive tablet is in different signal source channels, the whole machine module has different processing methods for touch data. When the signal source channel of the interactive tablet is the Android channel, it means that the interactive tablet is in the working channel of the whole machine module itself. Present the media content of the whole machine module. At this time, when the whole machine module receives the touch data sent by the touch components, the Android system performs the compatibility processing of the touch data (through the compatibility processing, the touch data generated by different types of touch components are processed into a unified format data, so that the processing process of the Android system can identify and respond), and respond to the touch data operation, and execute the corresponding operation. When the signal source channel of the interactive tablet is the host channel, when the whole machine module receives the touch data sent by the touch component, the Android system first performs the compatibility processing of the touch data, and then the Android system performs the compatibility processing of the touch data according to the preset host channel. The area size of the display screen is determined, and the touch data generated in the display screen area of the host channel is forwarded to the host channel through the second functional unit for response. When the signal source channel of the interactive tablet is the HDMI channel, when the whole machine module receives the touch data sent by the touch component, the Android system first performs the compatibility processing of the touch data, and performs the operation response of the touch data, and executes the corresponding operation. Then the Android system forwards the touch data generated in the display screen area of the HDMI channel to the touch line port (Touch out port) through the second functional unit according to the preset size of the display screen area of the HDMI channel. The external device of the port (Touch out port) responds.

请参见图2，为本申请实施例提供的一种显示屏的闪烁校正方法的流程示意图，所述方法应用于显示屏闪烁校正系统，所述系统包括控制板、显示屏、色彩分析仪以及PC主机。如图2所示，本申请实施例的所述方法可以包括以下步骤：Please refer to FIG. 2 , which is a schematic flowchart of a method for flicker correction of a display screen provided by an embodiment of the present application. The method is applied to a display screen flicker correction system, and the system includes a control board, a display screen, a color analyzer, and a PC host. As shown in FIG. 2 , the method of the embodiment of the present application may include the following steps:
S201，控制板接收校正指令，基于校正指令调用内置的在默认VCOM寄存器值下的预设闪烁画面，并将预设闪烁画面发送至显示屏进行显示。S201, the control board receives the calibration instruction, calls the built-in preset flickering picture under the default VCOM register value based on the calibration instruction, and sends the preset flickering picture to the display screen for display.
其中，校正指令是由PC主机向控制板发送的，用于指示控制板读取预先存储在控制板的存储器的预设闪烁画面数据，并且指示控制板将该预设闪烁画面数据发送至显示屏，显示屏基于该预设闪烁画面数据显示预设闪烁画面。PC主机上安装有闪烁校正工具，在运行闪烁校正程序时，向控制板发送校正指令。The correction instruction is sent by the PC host to the control board, and is used to instruct the control board to read the preset flickering picture data pre-stored in the memory of the control board, and instruct the control board to send the preset flickering picture data to the display screen , and the display screen displays a preset blinking image based on the preset blinking image data. A flicker correction tool is installed on the PC host, and when the flicker correction program is run, a correction command is sent to the control panel.
可以理解的是，将预先存储在控制板的预设闪烁画面数据对应的VCOM寄存器的值称作默认VCOM寄存器值。预设闪烁画面就是一种基于显示屏型号的特定闪烁画面，该特定闪烁画面是一种存在闪烁现象的彩色画面。不同尺寸的显示屏，不同型号的显示屏，以及不同厂商的显示屏，预设闪烁画面都是不一样的。闪烁现象就是在看液晶显示器的页面时，页面会有闪烁的感觉。由于液晶显示屏显示采用AC交流驱动原理，每帧刷新完毕所有像素点就要进行一次极性变化，如果原来施加在液晶显示屏子像素两端电极的电压为正极性电压(液晶两端电极中SOURCE电压与VCOM电极电压之差，如果为正，则正极性电压，如果为负，则为负极性电压)，一帧画面刷新过后就要切换到负极性电压。如果此时正负电压不对称，直接导致此时画面会出现图像颜色明暗的不一致，这就是闪烁现象。由于液晶显示屏目前基本都采用60Hz，即一秒刷新60次，而人眼对闪烁的感受，从30Hz开始下降，当频率超过60Hz时，人眼对闪烁的感受，会大幅度地下降也就无法感受到闪烁的存在。It can be understood that the value of the VCOM register corresponding to the preset flickering picture data pre-stored in the control board is referred to as the default VCOM register value. The preset flickering picture is a specific flickering picture based on the model of the display screen, and the specific flickering picture is a color picture with flickering phenomenon. Different sizes of displays, different models of displays, and displays from different manufacturers have different preset flashing images. The flickering phenomenon is that the page will flicker when looking at the page of the LCD monitor. Since the LCD display adopts the AC drive principle, all pixels must undergo a polarity change after each frame is refreshed. The difference between the SOURCE voltage and the VCOM electrode voltage, if it is positive, it is a positive voltage, if it is negative, it is a negative voltage), after a frame of picture is refreshed, it will switch to a negative voltage. If the positive and negative voltages are not symmetrical at this time, it will directly lead to the inconsistency of the image color on the screen at this time, which is the flickering phenomenon. Since the LCD screen basically adopts 60Hz, that is, refreshes 60 times per second, and the human eye's perception of flicker starts to decrease from 30Hz. When the frequency exceeds 60Hz, the human eye's perception of flicker will be greatly reduced. Can't feel the presence of flickering.
S202，色彩分析仪读取预设闪烁画面对应的闪烁测试值，并将闪烁测试值发送至PC主机。S202, the color analyzer reads the flicker test value corresponding to the preset flicker picture, and sends the flicker test value to the PC host.
具体的，色彩分析仪的一端和显示屏相连，色彩分析仪的另一端和PC主机相连，用于测量显示屏显示的预设闪烁画面对应的闪烁值，将此时在默认VCOM寄存器值下的预设闪烁画面对应的闪烁值称作闪烁测试值。色彩分析仪还用于将闪烁测试值发送至PC主机。Specifically, one end of the color analyzer is connected to the display screen, and the other end of the color analyzer is connected to the PC host, which is used to measure the flicker value corresponding to the preset flicker picture displayed on the display screen. The flicker value corresponding to the preset flicker screen is called the flicker test value. The color analyzer is also used to send flicker test values to the host PC.
S203，PC主机接收闪烁测试值，并基于闪烁测试值调整默认VCOM寄存器值，获取在不同VCOM寄存器值下的闪烁校正值，并将闪烁校正值中的最小值对应的VCOM寄存器值通过控制板写入显示屏。S203, the PC host receives the flicker test value, adjusts the default VCOM register value based on the flicker test value, obtains flicker correction values under different VCOM register values, and writes the VCOM register value corresponding to the minimum value of the flicker correction values through the control board into the display.
可以理解的是，如图3所示，驱动芯片的内部寄存器值和VCOM电压值呈线性变化关系，而VCOM电压值与闪烁值的关系如图4所示，可以看出闪烁值与VCOM电压值呈近似抛物线的走势。而从驱动芯片手册可以查到，VCOM电压值与驱动芯片内部VCOM寄存器的VCOM值呈线性关系。因此，若是找到曲线中的最低点，也就是说一旦设置了驱动芯片内部VCOM寄存器的VCOM值，对应的闪烁值最小，此时液晶显示屏的显示效果最佳，闪烁也即抖动最小。It can be understood that, as shown in Figure 3, the internal register value of the driver chip and the VCOM voltage value have a linear relationship, and the relationship between the VCOM voltage value and the flicker value is shown in Figure 4, it can be seen that the flicker value and the VCOM voltage value An approximate parabolic trend. It can be found from the driver chip manual that the VCOM voltage value has a linear relationship with the VCOM value of the VCOM register inside the driver chip. Therefore, if the lowest point in the curve is found, that is to say, once the VCOM value of the VCOM register inside the driver chip is set, the corresponding flicker value is the smallest. At this time, the display effect of the liquid crystal display is the best, and the flicker is the smallest jitter.
具体的，可以通过调节VCOM寄存器值，不同VCOM寄存器值下对应的闪烁值，在本申请实施例中称为闪烁校正值，通过调节VCOM寄存器值来找到最小的闪烁校正值，进一步地，再将最小的闪烁校正值对应的VCOM寄存器值通过控制板写入显示屏中。Specifically, by adjusting the VCOM register value, the corresponding flicker values under different VCOM register values are called flicker correction values in this embodiment of the present application, and the minimum flicker correction value can be found by adjusting the VCOM register values. The VCOM register value corresponding to the minimum flicker correction value is written into the display screen through the control board.
S204，显示屏以最小值对应的VCOM寄存器值进行画面显示。S204, the display screen displays the screen with the VCOM register value corresponding to the minimum value.
具体的，确定最小的闪烁校正值对应的VCOM寄存器值之后，显示屏就可以基于该VCOM寄存器值进行画面显示，此时显示屏显示的画面不再有闪烁现象，或者说不再有人眼可以感觉到的闪烁现象。Specifically, after determining the VCOM register value corresponding to the minimum flicker correction value, the display screen can display the picture based on the VCOM register value. At this time, the picture displayed on the display screen no longer has flickering phenomenon, or the human eye can no longer feel it. flickering phenomenon.

请参见图5，为本申请实施例提供的一种显示屏闪烁校正方法的流程示意图。如图5所示，本申请实施例的所述方法可以包括以下步骤：Please refer to FIG. 5 , which is a schematic flowchart of a display screen flicker correction method according to an embodiment of the present application. As shown in FIG. 5 , the method of the embodiment of the present application may include the following steps:
S501，控制板通过USB转串口连接线接收PC主机发送的校正指令，基于所述校正指令调用内置的在默认VCOM寄存器值下的预设闪烁画面，并将预设闪烁画面发送至所述显示屏进行显示。S501, the control board receives the correction instruction sent by the PC host through the USB-to-serial connection cable, calls the built-in preset flickering picture under the default VCOM register value based on the correction instruction, and sends the preset flickering picture to the display screen to display.
S502，色彩分析仪读取预设闪烁画面对应的闪烁测试值，并通过USB连接线将闪烁测试值发送至PC主机。S502, the color analyzer reads the flicker test value corresponding to the preset flicker picture, and sends the flicker test value to the PC host through a USB connection line.
具体的，S501～S502可参见图2中的S201～S202，在此不再赘述。Specifically, for S501 to S502, reference may be made to S201 to S202 in FIG. 2, and details are not described herein again.
S503，PC主机接收闪烁测试值，并基于闪烁测试值调整默认VCOM寄存器值，获取在不同VCOM寄存器值下的闪烁校正值，并将闪烁校正值中的最小值对应的VCOM寄存器值通过控制板写入显示屏。S503, the PC host receives the flicker test value, adjusts the default VCOM register value based on the flicker test value, obtains flicker correction values under different VCOM register values, and writes the VCOM register value corresponding to the minimum value of the flicker correction values through the control board into the display.
具体的，PC主机基于闪烁测试值调整默认VCOM寄存器值，由于驱动芯片的内部寄存器值和VCOM电压值呈线性关系，VCOM电压值和闪烁值呈抛物线关系，调整VCOM寄存器值即可调整闪烁值。在调整VCOM寄存器值的过程中，每一次调整VCOM寄存器值，都将调整后的VCOM寄存器值作为默认VCOM寄存器值，控制板指示显示屏按照默认VCOM寄存器值显示预设闪烁画面，色彩分析仪读取当前预设闪烁画面对应的闪烁测试值，并将该闪烁测试值发送至PC主机，PC主机接收该闪烁测试值，判断闪烁测试值是否达到最小值，若当前闪烁测试值不是最小值，PC主机继续调整VCOM寄存器值，重复上述过程，直至确定闪烁测试值中的最小值。Specifically, the PC host adjusts the default VCOM register value based on the flicker test value. Since the internal register value of the driver chip has a linear relationship with the VCOM voltage value, and the VCOM voltage value and the flicker value have a parabolic relationship, the flicker value can be adjusted by adjusting the VCOM register value. In the process of adjusting the VCOM register value, each time the VCOM register value is adjusted, the adjusted VCOM register value is used as the default VCOM register value, and the control board instructs the display to display the preset flickering screen according to the default VCOM register value, and the color analyzer reads Take the flicker test value corresponding to the current preset flicker screen, and send the flicker test value to the PC host. The PC host receives the flicker test value and judges whether the flicker test value reaches the minimum value. If the current flicker test value is not the minimum value, the PC The host continues to adjust the VCOM register value and repeats the above process until the minimum value of the flicker test values is determined.
在一种可能的实施方式中，通过调整VCOM寄存器值来确定闪烁测试值中的最小值，具体可以在预设的VCOM寄存器值范围中确定VCOM寄存器中值，进一步的，确定该VCOM寄存器中值对应的预设闪烁画面的闪烁中值。然后可以确定第一寄存器值范围和第二寄存器值范围，第一寄存器值范围可以定义为预设的VCOM寄存器值范围中的起点到VCOM寄存器中值，第二寄存器值范围可以定义为VCOM寄存器中值到预设的VCOM寄存器值范围中的终点。进一步的，可以在第一寄存器值范围中获取第一VCOM寄存器值，确定该第一VCOM寄存器值对应的预设闪烁画面的第一闪烁值。可以在第二寄存器值范围中获取第二VCOM寄存器值，确定该第二VCOM寄存器值对应的预设闪烁画面的第二闪烁值。进一步的，可以比较第一闪烁值、第二闪烁值和闪烁中值之间的大小，确定最小的闪烁值所对应的VCOM寄存器值所在的范围。In a possible implementation manner, the minimum value in the flicker test value is determined by adjusting the VCOM register value, specifically, the VCOM register median value may be determined in a preset VCOM register value range, and further, the VCOM register median value is determined The median flicker value of the corresponding preset flicker screen. Then the first register value range and the second register value range can be determined, the first register value range can be defined as the starting point in the preset VCOM register value range to the value in the VCOM register, and the second register value range can be defined as in the VCOM register value to the end of the preset VCOM register value range. Further, the first VCOM register value may be acquired in the first register value range, and the first flickering value of the preset flickering picture corresponding to the first VCOM register value is determined. The second VCOM register value may be acquired in the second register value range, and the second flickering value of the preset flickering screen corresponding to the second VCOM register value is determined. Further, the magnitudes between the first flicker value, the second flicker value, and the median flicker value may be compared to determine the range of the VCOM register value corresponding to the smallest flicker value.
若第一闪烁值>闪烁中值>第二闪烁值，那么可以确定最小的闪烁值所对应的VCOM寄存器值所在的范围为第二寄存器值范围。进一步的，在第二寄存器值范围中确定最小的闪烁值对应的VCOM寄存器值。此时，可以按照上述取中值的方法进一步缩小最小的闪烁值所对应的VCOM寄存器值所在的范围，直至调整到相邻的两个VCOM寄存器值的差值小于或者等于预设阈值时，停止调整默认VCOM寄存器值。比如，预设阈值可以设置为1，可以是调整到相邻的两个VCOM寄存器值的差值小于或者等于1时，停止调整默认VCOM寄存器值。If the first flickering value>the median flickering value>the second flickering value, then it can be determined that the range of the VCOM register value corresponding to the smallest flickering value is the second register value range. Further, the VCOM register value corresponding to the smallest flicker value is determined in the second register value range. At this time, the range of the VCOM register value corresponding to the smallest flicker value can be further narrowed according to the method of taking the median value, until the difference between the adjacent two VCOM register values is less than or equal to the preset threshold, stop Adjust the default VCOM register value. For example, the preset threshold may be set to 1, which may be adjusted to stop adjusting the default VCOM register value when the difference between the values of two adjacent VCOM registers is less than or equal to 1.
按照上述VCOM寄存器值的调整过程，可以确定闪烁校正值中的最小值对应的VCOM寄存器值，并通过控制板将该VCOM寄存器值写入显示屏的非易失性存储器中。According to the above adjustment process of the VCOM register value, the VCOM register value corresponding to the minimum value in the flicker correction value can be determined, and the VCOM register value can be written into the non-volatile memory of the display screen through the control board.
举例来说：VCOM寄存器值范围为0-255，取寄存器中值127，第一寄存器值范围为0-127，第二寄存器值范围为128-255，在第一寄存器值范围中取值55，在第二寄存器值范围中取值156，分别确定127对应的预设闪烁画面对应的闪烁中值，55对应的预设闪烁画面对应的第一闪烁值，156对应的预设闪烁画面对应的第二闪烁值。第一闪烁值>闪烁中值>第二闪烁值，那么可以确定最小的闪烁值对应的VCOM寄存器值为128-255。进一步的，在128-255取中值，以中值为界限分为两个范围，按照上述过程缩小最小的闪烁值对应的VCOM寄存器值范围，以此类推，若比较的VCOM寄存器值分别为223、224和225，那么对比223对应的闪烁值、224对应的闪烁值以及225对应的闪烁值，确定出224对应的闪烁值最小，那么可以确定闪烁校正值的最小值对应的VCOM寄存器值为224，进一步的，通过控制板将224写入显示屏中。For example: the VCOM register value range is 0-255, the value in the register is 127, the first register value range is 0-127, the second register value range is 128-255, the value in the first register value range is 55, In the second register value range, take a value of 156, respectively determine the median flicker value corresponding to the preset flicker picture corresponding to 127, the first flicker value corresponding to the preset flicker picture corresponding to 55, and the first flicker value corresponding to the preset flicker picture corresponding to 156. Two blinking values. The first flickering value>the median flickering value>the second flickering value, then it can be determined that the VCOM register value corresponding to the smallest flickering value is 128-255. Further, take the median value at 128-255, divide it into two ranges with the median value, and reduce the VCOM register value range corresponding to the smallest flicker value according to the above process, and so on, if the compared VCOM register values are 223. , 224 and 225, then compare the flicker value corresponding to 223, the flicker value corresponding to 224, and the flicker value corresponding to 225, and determine that the flicker value corresponding to 224 is the smallest, then it can be determined that the minimum value of the flicker correction value corresponds to the VCOM register value of 224 , and further, write 224 into the display screen through the control panel.
S504，控制板将内置的预设闪烁画面删除。S504, the control panel deletes the built-in preset flashing screen.
具体的，控制板将闪烁校正值中的最小值对应的VCOM寄存器值写入显示屏的非易失性存储器中之后，可以将内置在控制板中的、与显示屏型号匹配的预设闪烁画面删除。Specifically, after the control board writes the VCOM register value corresponding to the minimum value of the flicker correction values into the non-volatile memory of the display screen, the preset flickering screen built in the control board and matching the display model can be written delete.
