[0049] The present application provides a display method, a readable storage medium and a display device for a display panel, which will be described in detail below. The description order of the following embodiments does not limit the preferred order of the embodiments of the present application.

[0050] Please refer to Figure 1 , Figure 1 which is a flowchart of the display method for the display panel provided by the present application. The present application provides a display method for a display panel, which includes the following steps:

[0051] S10. Obtain at least one frame of display data of the input picture.

[0052] Several virtual lines are added to the head and tail of the display data of each frame in the valid display data. Therefore, when it is necessary to match different manufacturers' timing controllers or system chips on the display panel, there may be incompatibility between the display panel and the timing controller or system chip, resulting in abnormal display of the first few lines during display. Therefore, in order to make the display panel and the timing controller or system chip compatible and solve the problem of abnormal display of the first few lines during display, this application obtains at least one frame of display data of the input picture and adjusts the display data of the input picture. Of course, it is also possible to adjust the display data of each frame of the input picture, that is, it is possible to obtain the display data of each frame of the input picture, so that the input picture can be comprehensively adjusted.

[0053] S20. Remove the virtual lines in each frame of the display data to obtain valid display data.

[0054] Since the number of virtual lines in each frame of the display data is different from the number of virtual lines at the head or tail of the normal display data of each frame when the display panel displays the picture normally, it is necessary to remove the virtual lines in each frame of the display data to obtain valid display data, and the valid display data no longer includes virtual lines.

[0055] It should be noted that each frame of display includes valid display and virtual lines at the head and tail of the valid display. The valid display refers to the image display stage.

[0056] S30. Obtain the number N of virtual lines at the head or tail of the normal display data of each frame when the display panel displays the picture normally.

[0057] S40. Add N virtual lines to the head and tail of the valid display data respectively to obtain compensated display data.

[0058] After this application obtains the number N of virtual lines at the head or tail of the normal display data of each frame, and then adds N virtual lines to the head and tail of the valid display data respectively to obtain compensated display data, the compensated display data can be normally displayed on the display panel.

[0059] S50. Display according to the compensated display data.

[0060] In summary, this application removes the virtual lines in each frame of the display data of the input picture to obtain valid display data, and then adds N virtual lines to the head and tail of the valid display data respectively to obtain compensated display data. The compensated display data can be normally displayed on the display panel, thus solving the problem of abnormal display of the first few lines during display caused by the incompatibility between the display panel and the timing controller or system chip.

[0061] It should be noted that, in the above process, the use of steps S10, S20, S30, S40, and S50 to describe the process of the display method of the display panel of the present application is only for facilitating the understanding of the method process, and does not limit the specific step sequence of the display method of the display panel of the present application. The display method of the display panel of the present application may also have other step sequences that can achieve the object of the present invention, which are not limited herein.

[0062] In some embodiments, please refer to Figure 2 , Figure 2 which is a flowchart of an embodiment of step S20 of the display method of the display panel provided by the present application. The S20 step includes:

[0063] S21. Obtain the display duration T of the virtual row located at the head or tail of each frame of the display data.

[0064] Since virtual rows are added at the head and tail of the effective display data of each frame of the display panel, by obtaining the display duration T of the virtual row located at the head or tail of each frame of the display data, the position of the virtual row in each frame of the display data can be known.

[0065] S22. Remove the data with a display duration of T at the head and tail of each frame of the display data respectively to obtain the effective display data.

[0066] After obtaining the display duration T of the virtual row located at the head or tail of each frame of the display data, it is only necessary to remove the data with a display duration of T at the head and tail of each frame of the display data to obtain the effective display data, and the effective display data is the data for image display.

[0067] In some embodiments, please refer to Figure 3 , Figure 3 which is a flowchart of the first embodiment of step S21 of the display method of the display panel provided by the present application. The S21 step includes:

[0068] S211. Obtain the timing signal of the screen display to obtain a first signal and a second signal, where the first signal is the start signal of the first frame of display data, and the second signal is the clock signal when the first frame of effective display data starts to be displayed;

[0069] S212. Calculate the time difference between the first signal and the second signal on the timing signal of the first frame of display data, and the time difference is the display duration T of the virtual row located at the head of each frame of the display data.

[0070] The start signal of the first-frame display data is the signal indicating the start of the first-frame display data. The time between the start signal of the first-frame display data and the clock signal at which the first-frame valid display data starts to be displayed is the time for a virtual line display. Therefore, by obtaining the time difference between the first signal and the second signal on the timing signal of the first-frame display data, the display duration T of the virtual line at the head of each frame of the display data can be obtained.

[0071] Please refer to Figure 4 , Figure 4 FIG. is a timing diagram of the frame start signal, clock signal, and data signal for screen display, where STV is the timing diagram of the frame start signal, CLK is the timing diagram of the clock signal, and data is the timing diagram of the data signal. The frame start signal is the separation signal between each frame. After the start signal of the first-frame display data starts, after the duration of a virtual line, the clock signal starts to send the signal indicating the start of the first-frame valid display data. Therefore, the time between the start signal of the first-frame display data and the clock signal at which the first-frame valid display data starts to be displayed is the time for the virtual line display at the head of each frame of the display data.

[0072] The data signal is the signal when the display panel is in the state of displaying valid display data. That is, the difference between the duration when each frame of the data signal is in the state of displaying valid display data and the duration of each frame is the duration of the virtual lines at the head and tail of each frame of the display data. Specifically, the first signal is a high-level signal. The second signal is the falling edge signal of the clock signal.

[0073] In some embodiments, please refer to Figure 5 , Figure 5 FIG. is a flowchart of step S30 of the display method of the display panel provided by the present application.

[0074] Existing timing controllers generally do not have optical compensation and automatic debugging functions. A functional chip with optical compensation and automatic debugging functions needs to be combined with the timing controller to complete the optical compensation and automatic debugging functions. The above functional chip can also be the driving chip of the display panel. To cooperate with optical compensation and automatic debugging, a memory is also provided on the display panel. The memory stores the test display data for optical compensation and automatic debugging. The memory is a flash memory, and the flash memory is generally set on a circuit board (referred to as the X-board, X plate) connected to the display panel. Specifically, the X-board and the display panel are connected by a flexible circuit board. In addition, the timing controller and the functional chip of the display panel are generally set on another separate circuit board (referred to as the Control board, control board), and the control board also includes a flash memory, which stores the functional code for controlling the operation of the TCON function. The control board is connected to the X-board and controls the display panel to light up.

[0075] The display panel includes a memory, and test display data of the display panel is stored on the memory. The step S30 includes:

[0076] S31. Obtain the storage information of the test display data on the memory;

[0077] S32. Obtain the number of virtual rows located at the head or tail end of the test display data according to the storage information;

[0078] The number of virtual rows located at the head or tail end of the test display data is the number of virtual rows N located at the head or tail end of each frame of normal display data when the display panel is in a normal display screen.

[0079] The test display data includes test display data for optical compensation and test display data for automatic debugging.

[0080] In some embodiments, the storage information includes the identifier of the virtual row of the test display data on the memory. The step S32 includes:

[0081] Obtain the number of virtual rows located at the head or tail end of the test display data according to the identifier. Specifically, obtain the number of the identifiers, and divide the number of the identifiers by 2 to obtain the number of virtual rows located at the head or tail end of the test display data.

[0082] The memory stores test display data for optical compensation and automatic debugging. In the memory, the data of the virtual row all starts with a corresponding identifier. For example, when part of the data in the memory is: FF 06 14....., FF 08 16....., at this time FF is used as the identifier of the data of the virtual row on the memory. Then the data starting with FF in the memory is the data of the virtual row. By obtaining the number of the data starting with FF, the number of virtual rows of the test display data can be known. Since there are virtual rows at both the head and tail ends of the test display data, the number of virtual rows located at the head or tail end of the test display data is obtained by dividing the number of identifiers of the data of the virtual row on the memory by 2.

[0083] In other embodiments of the present application, please refer to Figure 6 and Figure 4 , Figure 6 is a flowchart of the second embodiment of step S21 of the display method of the display panel provided by the present application. The S21 includes:

[0084] S213. Obtain the timing signal of the displayed screen to get a first signal and a second signal, where the first signal is the start signal of each frame of display data, and the second signal is a rising edge signal or a falling edge signal. The rising edge signal is the rising edge at the effective display start position in the data signal corresponding to the start signal of each frame of the display data, and the falling edge signal is the falling edge at the effective display start position in the data signal corresponding to the start signal of each frame of the display data;

[0085] S214. Calculate the time difference between the first signal and the second signal on the driving timing of the first frame of display data. The time difference is the display duration T of the virtual row at the head of each frame of the display data.

[0086] In the above embodiment, the first signal is the start signal of each frame of display data, and the second signal is a rising edge signal or a falling edge signal. The rising edge signal is the rising edge at the effective display start position in the data signal corresponding to the start signal of each frame of the display data, and the falling edge signal is the falling edge at the effective display start position in the data signal corresponding to the start signal of each frame of the display data. The data signal is a signal that enables the display panel to display effective display data, that is, when the sub-pixels of the display panel are turned on by the data signal, the display panel is in the state of displaying effective display data. Therefore, when the sub-pixels of the display panel are in the display state when the data signal is at a high level, the second signal is the rising edge at the effective display start position of each frame of the data signal; when the sub-pixels of the display panel are in the display state when the data signal is at a low level, the second signal is the falling edge at the effective display start position of each frame of the data signal.

[0087] The start signal of the first frame of display data is the signal at the start of the first frame of display data, and the time between the start signal of each frame of display data and the rising edge or falling edge at the effective display start position of each frame of the data signal is the display time of the virtual row. Therefore, by obtaining the time difference between the first signal and the second signal on the timing signal of each frame of the display data, the display duration T of the virtual row at the head of each frame of the display data can be obtained.

[0088] In some other embodiments of the present application, please refer to Figure 7 and Figure 4 , Figure 7 is a flowchart of the third embodiment of step S21 of the display method of the display panel provided by the present application. The S21 includes:

[0089] S215. Obtain the duration of each frame;

[0090] S216. Obtain the duration when the data signal is in the effective display state;

[0091] S217. Calculate the time difference between the duration of each frame and the duration when the data signal is in the valid display state, and divide the time difference by 2 to obtain the display duration T of the virtual line at the head or tail of the display data in each frame.

[0092] The duration of each frame includes the display duration of the valid display data and the display duration of the virtual lines at both ends of the valid display data. The data signal is the signal that enables the display panel to display the valid display data. The duration when the data signal is in the valid display state in each frame is the display duration of the valid display data. Therefore, the time difference between the duration of each frame and the duration when the data signal is in the valid display state in each frame can be obtained, and the time difference is divided by 2 to obtain the display duration T of the virtual line at the head or tail of the display data in each frame.
