Abstract

The embodiment of the invention provides an MIPI data processing method and device, a storage medium and a display terminal, and belongs to the technical field of integrated circuits. The method comprises the following steps: receiving an MIPI data stream, and sending the MIPI data stream to a data buffer area; analyzing the MIPI data stream according to a DSI time sequence specification to obtaina frame synchronization signal, a horizontal synchronization signal, an RGB pixel effective enable signal and RGB pixel data; compensating the frame synchronization signal or / and the horizontal synchronization signal according to set parameters to obtain a compensated frame synchronization signal or / and a compensated horizontal synchronization signal; and according to the compensated frame synchronization signal, the compensated horizontal synchronization signal, the RGB pixel effective enable signal and the RGB pixel data, outputting a DPI data stream according to a DPI timing sequence specification. Thus, by setting of the parameters for compensation, the matching performance of a master device and a slave device can be greatly improved, the compatibility is higher, and therefore the universality of a display screen in a mobile display device is improved.

Description

Technical field [0001] The embodiments of the present invention relate to the field of integrated circuit technology, and in particular, to a MIPI data processing method, device, storage medium, and display terminal. Background technique [0002] The Mobile Industry Processor Interface (MIPI) is an open standard customized for mobile application processors. The MIPI Display Serial Interface (DSI), as a high-speed display communication interface, is increasingly used on display terminals such as mobile phones and tablet computers. [0003] The data transmitted by the MIPI display serial interface is used for mobile display terminals. The display data sent is divided into command mode and video mode. The traditional method of parsing video mode MIPI data to DPI is to analyze the frame synchronization signal in DPI according to the DSI specification. VSYNC0, horizontal synchronization signal HSYNC0, RGB pixel effective enable signal DE, and RGB pixel data DB. Among them, VSYNC is the...

Problems solved by technology

[0005] 2) When the mobile display terminal reads the slave device register during the interval of sending DPI data, because the returned data is low-speed, it will take up the time for the mobile display terminal to generate HSYNC, and even affect the generation of VSYNC, resulting in abnormal screen display

[0006] 3) When the mobile display terminal considers reducing power consumption in different modes and adopts frame frequency conversion, it will affect the compensation

[0007] 4) When the mobile display terminal makes the clock enter a low speed during the gap period of DPI data to reduce power consumption, it will affect the compensation
