Liquid crystal display aging test method and liquid crystal display

Abstract

The invention discloses a liquid crystal display aging test method comprising the following steps: after detecting an aging test signal, an aging test module of a timing controller sends a first command signal to a timing control module of the timing controller; and the timing control module outputs a display signal to a liquid crystal display panel according to the first command signal in order to drive the liquid crystal display panel in a point reversing mode. The liquid crystal display aging test method of the invention has high bad block rate. The invention further discloses a liquid crystal display.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to an aging test method of a liquid crystal display and a liquid crystal display. Background technique [0002] With the birth of more and more display devices and brands, the competition of Liquid Crystal Display (LCD) is becoming more and more fierce, and the requirements of customers for LCD are getting higher and higher. Customers or LCD manufacturers It is hoped that abnormal products will be checked before the module is shipped, so as not to affect customers. [0003] For liquid crystal displays with damaged liquid crystal cells and module components but no abnormal display, if they flow to the client, the largest proportion of liquid crystal cell (cell) line defects, slight damage to electronic components, etc., will easily cause liquid crystal displays to be damaged during customer use. Flaws (such as disconnection, corrosion, etc.) or abnormalities have a serious i...

Problems solved by technology

[0003] For liquid crystal displays with damaged liquid crystal cells and module components but no abnormal display, if they flow to the client, the largest proportion of liquid crystal cell (cell) line defects, slight damage to electronic components, etc., will easily cause liquid crystal displays to be damaged during customer use. Flaws (such as disconnection, corrosion, etc.) or abnormalities have a serious impact on product quality, so now many testing methods have been proposed, such as Aging test (aging test)

With the application of new technologies and new designs, the conventional aging test can no longer meet the power consumption requirements of the load burn-in, and cannot detect all defective products very effectively, resulting in a low detection rate of defective products.
