Problems solved by technology

Now the mainstream process is vacuum back-plating ITO transparent conductive film. Of course, there are several process methods for back-plating ITO transparent conductive film. Considering the problems of organic material pollution, scratches and foreign objects in the production process, most LCD panel manufacturers The method of vacuum coating the ITO transparent conductive film after the cells are formed into a box first, but this production method needs to consider that after the cells are formed into a box, water vapor will enter the box during the cleaning process before the vacuum coating of the transparent conductive film, which will affect the transparency of the ITO. The resistance of the conductive film layer makes the film layer unable to play the role of electromagnetic shielding, which in turn affects the performance of the product

Embodiment 1

[0015] Embodiment 1: such as figure 1 As shown, a method for preparing a liquid crystal cell of an IPS liquid crystal screen, the steps are: setting a plurality of preset liquid crystal coverage areas at intervals on a CF substrate, and the periphery of the single preset liquid crystal coverage area is surrounded by a frame glue to form a small frame 2 , the preset liquid crystal coverage area can be any number according to the size and model of the IPS liquid crystal screen, and is distributed on the CF substrate in an array. B. On the border of the CF substrate, use the frame glue to form a large frame 3, and surround all the small frames in step A. C. Drop liquid crystal on the TFT substrate through the liquid crystal dropping process; D. Drop the liquid crystal in step C. The surface of the TFT substrate is bonded to the surface of the CF substrate with a frame in step B to form a Cell liquid crystal cell. The large frame is provided with an opening 4, and the opening 4 i...

Embodiment 2

[0016] Embodiment 2: as figure 2 As shown, the difference from Embodiment 1 is that the number of openings 4 provided on the large frame 3 is four, and they are arranged symmetrically in pairs on both sides of the large frame, and the distance between the openings is 15 mm. Both sides of the opening are provided with inner and outer bars in parallel, the opening 4 is in the middle of the two bars, the length of the inner bar 5 is 60mm, and the length of the outer bar 6 is 120mm. The distance between the outer rail 6 and the inner rail 5 is 3mm. The height and width of the outer rail and the inner rail are the same as the height and width of the large frame 3 .

Embodiment 3

[0017] Embodiment 3: as image 3 As shown, the difference from Embodiment 2 is that the number of openings 4 provided on the large frame 3 is four, and they are symmetrically distributed on the four sides of the large frame.

Abstract

The invention relates to the technical field of IPS liquid crystal display screen manufacturing, in particular to an IPS liquid crystal display screen liquid crystal box preparation method. The methodincludes: A, arranging at least one preset liquid crystal coverage area at intervals on a CF substrate, wherein a small frame is formed on the periphery of each preset liquid crystal coverage area through frame glue; B, enclosing to form a large frame, which encloses all small frames in the step A, on the periphery of the CF substrate through frame glue; C, dropping liquid crystal on a TFT substrate through a liquid crystal dropping process; D, fitting the surface, with the dropped liquid crystal in the step C, of the TFT substrate to the surface, with the frame, of the CF substrate in the step B to form a Cell liquid crystal box. The large frame is provided with an opening to prevent water vapor from entering the Cell box in cleaning and causing adverse influences on subsequent products.The whole Cell box is uniformly stressed, and frame impression is avoided.

Description

technical field [0001] The invention relates to the technical field of manufacturing IPS liquid crystal screens, in particular to a method for preparing a liquid crystal box of an IPS liquid crystal screen. Background technique [0002] With the development of liquid crystal display devices, the liquid crystal display screens in the mainstream market are now divided into two types, one is TN type; the other is IPS type. TN panel, full name Twisted Nematic (twisted nematic) panel, is a type of display screen on the market. Because of its low production cost, the TN-type display screen has become the most widely used basic-level LCD screen, and is widely used in the mainstream low-end LCD screens on the market. The IPS type is a new type of liquid crystal display that has only been developed in the past ten or twenty years. However, due to its fast response speed, large viewing angle, and true color, the IPS liquid crystal screen is more and more popular among people. High-e...
