Problems solved by technology

Due to its non-flat shape, the 3D glass cover cannot be compared with the 2D glass cover (that is, the glass cover that is flat as a whole) or the 2.5D glass cover (that is, the edge is curved, and the other areas are flat). ) is directly placed on the test platform, so it is necessary to design a special fixture for the 3D glass cover for support, otherwise the ball drop test of the 3D glass cover is unreliable and the test results are uncertain

Embodiment Construction

[0027] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0028] see figure 1 , the present invention provides a supporting jig for a ball drop test, comprising: a platform 10 and a raised portion 20 provided on the platform 10;

[0029] The raised portion 20 is used to place a glass cover, and the edge of the glass cover coincides with the edge of the raised portion 20 .

[0030] It should be noted that when the glass cover is subjected to a ball drop test, the glass cover is placed on the raised portion 20 of the supporting jig, and the edge of the glass cover coincides with the edge of the raised portion 20, that is, the glass cover It can be placed on the support jig stably. When the ball falls from a fixed height and hits the position on the glass cover where the strength needs to be tested, si...

Abstract

The invention provides a support fixture and a falling ball test method. The support fixture for testing the falling ball comprises a platform and a raised portion disposed on the platform. The raisedportion is used for placing a glass cover plate. The edge of the glass cover overlaps the edge of the raised portion, and the glass cover can be placed on the support fixture smoothly when the falling ball is tested on the glass cover. The ball falls from a fixed height, impacts a position on the glass cover where strength is to be tested. The reliability of the falling ball test of the glass cover can be improved, and the strength test results of the glass cover have deterministic since the glass cover is placed on the support fixture very smoothly.

Description

technical field [0001] The invention relates to the field of display technology testing, in particular to a support jig and a falling ball testing method. Background technique [0002] Thin Film Transistor (TFT) is the main driving element in current Liquid Crystal Display (LCD) and Active Matrix Organic Light-Emitting Diode (AMOLED). It is related to the display performance of the flat panel display device. [0003] Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to pour liquid crystal molecules between the thin film transistor array substrate (ThinFilm Transistor Array Substrate, TFT Array Substrate) and the color filter (ColorFilter, CF) substrate, and apply pixel voltage on the two substrates respectively. and the common voltage, through the electric field formed between the pixel voltage an...
