Embodiment Construction
[0025] The present invention will be further described below in conjunction with accompanying drawing.
[0026] figure 2 The structure of the liquid crystal panel 1 in one embodiment of the present invention is shown. The liquid crystal screen 1 includes a color filter substrate 4 , an array substrate 3 , a sealant, and liquid crystals. The color filter substrate 4 and the array substrate 3 are parallel to each other. The frame glue is in the shape of a rectangular frame, and the frame glue is arranged between the color filter substrate 4 and the array substrate 3 . The frame glue, the color filter substrate 4 and the array substrate 3 form a box-shaped structure 2 . Liquid crystals are encapsulated in the cell-shaped structure 2 . The connecting end 5 of the array substrate 3 extends out of the box-shaped structure 2 .
[0027] The array substrate 3 includes a glass substrate 13, a thin film field effect transistor, a signal line 9, and an insulating layer. The glass s...

Abstract
The invention provides a liquid crystal display device and a liquid crystal screen thereof. The liquid crystal screen comprises an array substrate, a first terminal and a detection film are arranged on one surface of the array substrate, the detection film is separated from the first terminal, and pressure marks capable of being observed from one side of the array substrate deviating from the detection film can be formed on the detection film after conducting particles in an anisotropic conducting film press the detection film. After the detection film is connected with the anisotropic conducting film in a pressed manner, the number of the pressure marks on the unit area of the detection film and uniformity of the pressure marks distributed on the detection film can represent the number of the conducting particles on the unit area of the first terminal and distribution uniformity of the conducting particles respectively. Therefore, technical staff in the field can judge the compression joint effect of the liquid crystal screen according to the number of the pressure marks on the unit area of the detection film and uniformity of the pressure marks distributed on the detection film.
Description
technical field [0001] The invention relates to liquid crystal display technology, in particular to a liquid crystal display device and a liquid crystal screen thereof. Background technique [0002] Such as figure 1 As shown, in the manufacturing process of the liquid crystal display device, it is necessary to connect the connection terminal 101 of the liquid crystal screen 100 and the driving circuit of the liquid crystal screen to each other. For example, in the FOG (FPC on Glass) process, a flexible circuit board (FPC) is used to connect the LCD driver circuit board and the liquid crystal panel to each other. For example, in a COG (Chip on Glass) process, a liquid crystal display driving IC (integrated circuit) component is directly mounted on the liquid crystal display 100 . [0003] When using the FOG process (or using the COG process), when the connecting terminal 201 of the flexible circuit board 200 (or the connecting terminal on the LCD driver IC component) is con...
