A test method, device and terminal equipment adapted to different types of display screens

Abstract

The invention discloses a test method, device and equipment terminal for adapting to different types of display screens. The method comprises: acquiring pixel data of an image source and storing it in a first cache; reading pixel data from the first cache and storing the same into the second cache, and the starting line reading address between two adjacent frames of images is moved according to the preset interval line value; the pixel data is read from the second cache and stored in the third cache, and the two adjacent frames The starting pixel reading address between each row of data of the frame image is moved according to the preset interval pixel value; according to the vertical split screen mode required by the display screen to be tested, the pixels corresponding to each split screen are read from the third buffer Data; according to the number of channels and the clock cycle required by the display screen to be tested, bit width conversion is performed on the pixel data corresponding to each split screen to obtain a test image signal adapted to the display screen to be tested; the present invention can adapt to various needs of different split screens. The screen mode, number of channels, resolution and screen movement of the screen.

Description

technical field [0001] The invention belongs to the technical field of display panel testing, and more specifically relates to a testing method, device and terminal equipment adapted to different types of display screens. Background technique [0002] In the field of display panel testing, the test device needs to output test signals to light up the screen and test the various performances of the display screen; due to the diversification of the screen size, input interface, interface Lane number and split-screen mode of the display screen on the market , Some display screens also need to realize the picture movement function of the screen during the test. For example: common input interfaces include DP, HDMI, LVDS, VBYONE, MIPI interfaces, etc.; common split screen methods include no split screen, up and down 2 split screens, vertical 2 split screens, vertical 4 split screens, vertical 8 split screens, field Word split screen, etc.; common interface Lanes are 2, 4, 8, 16, ...
