Embodiment 1

[0096] Please combine Figure 9 and Figure 10 Shown, a kind of liquid crystal panel detection method comprises the following steps:

[0097] Step S100, setting the standard pressure recovery time T in the host computer 50;

[0098] Step S200, power on the liquid crystal panel 80 and light it up, and the host computer 50 controls the camera 40 to take a first shot of the liquid crystal panel 80 to obtain an image A;

[0099] Step S300, the upper computer 50 controls the operation of the driving mechanism 20, and the driving mechanism 20 drives the pressing assembly 30 to move to the detection position of the liquid crystal panel 80, and makes the pressing member 32 of the pressing assembly 30 collide with the liquid crystal panel 80, and at the same time touches and senses The unit 33 transmits the first electrical signal to the upper computer 50, and the upper computer 50 starts to calculate the set time t1 after receiving the first electrical signal;

[0100] Step S400, a...

Abstract

The invention relates to the technical field of liquid crystal panel detection, and provides a liquid crystal panel detection device and method. The liquid crystal panel detection device comprises a workbench, a driving mechanism, a pressure applying assembly, a camera and an upper computer. The workbench is used for placing a liquid crystal panel; the driving mechanism is mounted on the workbench; the pressure applying assembly comprises a bearing piece installed on the driving mechanism, a pressure applying piece which can be movably borne on the bearing piece up and down, and a contact sensing unit arranged between the bearing piece and the pressure applying piece, wherein the pressing piece is driven by the driving mechanism to abut against or be separated from the liquid crystal display panel; the camera is suspended above the liquid crystal display panel; and the driving mechanism, the contact sensing unit and the camera are electrically connected with the upper computer. High accuracy can be achieved when the liquid crystal display panel detection device is used for detecting the quality of the liquid crystal display panel, and an automatic detection mode is adopted, so thatthe detection efficiency is high.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panel detection, and in particular provides a liquid crystal panel detection device and method. Background technique [0002] Liquid crystal panels are widely used in display devices such as computers, mobile phones, and home appliances. After being pressed, the liquid crystal panel will undergo a short-term structural change. Produces a display effect that is almost opposite to the original display effect. This phenomenon is commonly known as "light leakage", and the time required for the LCD panel to return to normal after being pressed is called the pressure recovery time. At present, most manufacturers use LCD panels. Carry out a pressure recovery time test to judge whether the quality of the LCD panel is qualified. [0003] The existing methods for quality inspection of LCD panels are mainly by manually placing weights on the LCD panel to exert pressure on the LCD panel, and then quic...
