Embodiment Construction

[0039] Please refer to figure 1 , which shows a flowchart of a burn-in test method for a liquid crystal display according to a preferred embodiment of the present invention. The burn-in test method includes the following steps.

[0040] First, please also refer to figure 2 and image 3 , figure 2 A schematic diagram showing the hue angle of the HSI (Hue, Saturation, Intensity) color system, image 3 A schematic diagram illustrating a first implementation of the burn-in screen according to a preferred embodiment of the present invention. Such as image 3 As shown, in step S102, several burn-in frames F are played sequentially and repeatedly within a preset time. Adjacent burn-in frames (for example, a first burn-in frame FA1 and a second burn-in frame FA2 ) have strong color contrast at corresponding positions. Strongly contrasting colors such as figure 2 The hue (Hue) angle is substantially 180 ° different colors, such as red and cyan (Cyan), yellow and blue and gre...

Abstract

The invention provides a burn-in test method of a liquid crystal display, which comprises the following steps of sequentially and repeatedly playing a plurality of burn-in pictures within a preset time, wherein the corresponding parts of adjacent burn-in pictures have strong color contrast; playing a detected picture after the preset time; and detecting the quality of the detected picture. Because the strong color contrast can increase the drive load of the liquid crystal display , the burn-in test method can more efficiently detect the quality of the liquid crystal display.

Description

technical field [0001] The invention relates to a burn-in test method of a liquid crystal display, and in particular relates to a burn-in test method of a liquid crystal display with a burn-in screen with strong color contrast. Background technique [0002] Electronic products (such as mobile phones) all have a liquid crystal display. Electronic products will undergo a burn-in test on their LCD monitors before shipment to check whether the display function of the LCD monitors of electronic products is normal and stable. Electronic products will not be officially shipped until they pass the burn-in test. [0003] Generally speaking, the current burn-in test method is mostly to drive the LCD to continuously play a preset image. After the test lasts for a predetermined period of time, it is checked whether there is any defect in the display quality of the display screen. [0004] However, most of the preset images played in the current burn-in test are a piece of video, which...
