Abstract

The invention discloses a display driving method. The method includes the following steps: a display driving module detecting front N picture frames (N is an integer and N is greater than or equal to 2) in an image signal which is transmitted by a DSI interface of the MIPI of a main computer, computing a first time length of a vertical rear end region and a second time length of a vertical front end region of each of the front N picture frames, and if it is determined that the first time lengths are of the same length and are different from a preset vertical rear end value, and the second time lengths are of the same length and are different from a preset vertical front end value, updating the vertical rear end value with the first time lengths and updating the vertical front end value with the second time lengths, and based on a vertical synchronous signal, a vertical rear end set value and a vertical front end set value, outputting the display data of each picture frame to a display panel.

Description

【Technical field】

[0001] The present invention relates to a display driving method, in particular to a display driving method for image signals transmitted in Display Serial Interface (DSI) format of Mobile Industry Processor Interface (MIPI). 【Background technique】

[0002] see figure 1 As shown, an existing mobile terminal 1, such as a mobile phone, a tablet computer, etc., displays images in a way that the host computer 10 uses a Display Serial Interface (Display Interface) of the Mobile Industry Processor Interface (MIPI) for short. Serial Interface, referred to as DSI) (hereinafter referred to as the display serial interface of MIPI) transmits image signals including multiple frame data to the display driver module 21 of the flat panel display 20, and as figure 2 As shown, the display driving module 21 will generate a vertical synchronous signal VS according to the image signal, so as to control the display frequency of the display panel 22 of the flat-panel display 2...
