That is, in the present embodiment, the display screen itself analyzes and controls the relevant display parameters of the display timer element.
Continuing to explain by taking the embodiment in which the display screen is an IC screen as an example, the AP sends a serial port command through the MIPI to notify the driver IC to start the partitioned display, and after receiving the command, the driver IC adjusts hardware modules such as a crystal oscillator, Ram, Line Buffer, and a register, so as to realize switching between Gate Timing and Data Timing.
As another possible implementation manner, the display data amount of the display timer element of the target display area is generated according to the display instruction of the display screen, the display timer element of the target display area is driven according to the display data amount, that is, the data amount of each timer element, such as the display brightness value, is directly determined, and the corresponding parameter value is directly sent to the display timer for execution.
Continuing to explain by taking the embodiment in which the display screen is an IC screen as an example, the AP directly changes the transmission Data amount of the MIPI, and after the driving IC recognizes the corresponding display Data amount, adjusts each internal module to realize switching of Gate Timing and Data Timing.
Therefore, the display method of the display screen in the embodiment of the present application realizes reduction of Data amount and reduction of power consumption, and simultaneously satisfies switching of display modes, the practicability of the present application is strong, and the embodiment in which the display screen is an IC screen is continuously described as an example, as shown in fig. 7, Gata and Data signals output by the display screen driving IC have a certain correspondence with MIPI signals, MIPI outputs in one frame, the output mode is to output image signals line by line, and after the output of image signals of all lines is completed, output of the next frame is started. The control display screen also outputs the Gate Timing and Data Timing signals for each line, which is used for controlling the display refresh of each line, the Gate Timing outputs a pulse line by line, the Data Timing outputs different voltages for each line, and each pixel is controlled to display different brightness. When the display screen display mode is switched, MIPI, Gate Timing and Data Timing signals are switched along with the switching, and after the MIPI, the Gate Timing and the Data Timing signals are switched to corresponding display Data, the display screen displays different areas, so that the switching of the display screen display mode is realized, and the application effect of regional display is achieved.
