The invention discloses a display screen detection signal generation device and method. The generation device of the display detection signal includes a control module, a timing signal generation module, a data signal conversion module, a data parallel-to-serial module and a differential module, wherein the control module is used to obtain image data, and according to the pixel clock signal required by the display Generate a clock signal corresponding to the pixel clock signal; the timing signal generation module is used to generate a timing signal for controlling the output of the driver IC according to the clock signal; the data signal conversion module is used to convert image data into a TTL data signal; the data parallel to serial module It is used to convert the TTL data signal into a serial data signal; the differential module is used to perform mini-LVDS differential conversion on the serial data signal according to the timing signal. The invention realizes the detection of different display screens by realizing the matching between the mini-LVDS signal differential pair and the display screen during the signal conversion process.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of display screen detection, and in particular, to an apparatus and method for generating a display screen detection signal. Background technique [0002] With the rapid rise of the electronic automobile industry, the demand for LCD screens in the car is becoming more and more diversified. Whether it is the traditional central control platform, or the current instrument panel display, 3D parking, in-vehicle entertainment and automatic driving display, more and more The more you use the LCD display. This requires high reliability and diverse shapes of the LCD screen, and at the same time requires a clearer, more stable and highly anti-interference display. The above market-oriented demands will bring challenges to the driving technology of the LCD screen. [0003] Now Mini-LVDS technology is widely used in high-definition LCD screens. It is a low-voltage differential signal developed an...
