Embodiment 1

[0025] The present invention provides a liquid crystal panel withstand voltage testing device, which is combined below Figure 1 to Figure 3 The liquid crystal panel withstand voltage testing device is described in detail.

[0026] The liquid crystal panel pressure test device provided in this embodiment includes: a liquid tank 101 , a support column 104 , a liquid pipeline 106 , a fixed arm 107 , a lifting rod 108 and an inner hollow funnel 109 . The support column 104 is vertically arranged on both sides of the lifting rod 108, and the lifting rod 108 can be lifted up and down on the supporting column 104; the fixed arm 107 is fixed on the lifting rod 108, and the inner hollow funnel 109 is fixed on the lifting rod 108 by the fixed arm 107; One end of the pipeline 106 is connected to the liquid tank 101, and the other end is connected to the top of the inner hollow funnel 109, and the liquid crystal panel 105 to be tested is placed at the bottom of the liquid crystal panel w...

Embodiment 2

[0034] In this example, if figure 1 As shown, the liquid pipeline 106 includes an electric control valve 102 and a flow meter 103, the weight of the liquid required for the experiment can be obtained through the control of the control mechanism on the electric control valve 102, and the flow meter 103 can detect the amount of the passing liquid to ensure Experimental Accuracy. If the experiment needs to use multiple inner hollow funnels at the same time, it is necessary to set the same number of liquid pipelines, and each liquid pipeline is equipped with an electric control valve 102 and a flow meter 103 to ensure that the weight of the liquid in each inner hollow funnel is accurately.

[0035] Preferably, a liquid level controller is provided on the liquid tank 101, and the liquid level controller can be an electrode type liquid level controller, a float magnetic switch liquid level controller or other types of liquid level controllers. When the water level in the liquid ta...

Abstract

The present invention provides a liquid crystal panel pressure test device, the liquid crystal panel pressure test device includes a support column, a lifting rod, a fixed arm, an inner hollow funnel, a liquid pipeline and a liquid tank, and the lifting rod is arranged on the support On the column, the inner hollow funnel is fixed on the lifting rod through the fixed arm, and the liquid crystal panel to be tested is placed at the bottom of the inner hollow funnel; The liquid tank injects different amounts of liquid into the inner hollow funnel along the liquid pipeline and adjusts the height of the lifting rod to achieve tests of different weights and different pressing areas. At the same time, tests at different positions can also be achieved by adjusting the position of the support column , making the liquid crystal panel withstand voltage test more convenient, fast and efficient.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal panel withstand voltage test device. Background technique [0002] In display manufacturing, Thin Film Liquid Crystal Display (TFT-LCD) is composed of array substrate and color filter (Color Filter, CF), and the box is filled with liquid crystal (Liquid Crystal, LC) to synthesize a liquid crystal panel. The gap in the box is supported by a photo spacer (PS). The density and strength of PS and the amount of LC dripping affect the compression resistance of the LCD panel. If the compression resistance is not strong enough, the panel is prone to poor display brightness under pressure. Poor quality such as uniformity. [0003] At present, to test the pressure resistance of the panel, usually place a weight with a certain weight and a fixed radius on the LCD panel, press it on the panel, leave it for a period of time, and then confirm whether the LCD panel has de...
