Abstract

The embodiment of the invention discloses a method for dispersing spherical spacers, a liquid crystal panel and a display device. The method comprises the following steps of: forming a polyimide solution on a substrate; spraying the spherical spacers on the substrate with the polyimide solution; and solidifying the substrate to form a polyimide orientation film. Therefore, by adopting the method for dispersing the spherical spacers, the spherical spacers can be well fixed; and the problem that the thickness of a box is non-uniform because of movement under the impact of liquid crystals is solved.

Description

technical field

[0001] The invention relates to the manufacturing technology of liquid crystal panels, in particular to a method for dispersing spherical spacers, a liquid crystal panel and a display device. Background technique

[0002] In the manufacturing process of the liquid crystal panel, controlling the cell thickness of the liquid crystal panel is one of the key technologies. Such as figure 1 as shown, figure 1 It shows a technique commonly used at present to control the cell thickness of the liquid crystal panel, that is, after the alignment film 4 is coated and cured, the spherical spacer 3 is directly sprayed on the substrate 1 .

[0003] However, when spherical spacers are used, when the vacuum is opened to the atmosphere of the box, the atmospheric pressure is applied to the upper and lower substrates at the same time. Since the substrates are in a vacuum state, the liquid crystal between the substrates is rapidly diffused outward due to the action of the atmo...

Embodiment Construction

[0030] The basic idea of ​​the present invention is to fix the spherical spacer by utilizing the property of the adhesive of the polyimide solution and changing the spraying and curing process of the spherical spacer, effectively inhibiting the movement of the spherical spacer , which solves the uneven thickness of the cell caused by the impact of the liquid crystal on the spherical spacer.

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] image 3 The flow chart of the method for dispersing the spherical spacer of the embodiment of the present invention is shown, as image 3 As shown, in this embodiment, the method includes the following steps:

[0033] 301: forming a polyimide solution with a certain solid content on the substrate;

[0034] Wherein, the solid content of the polyimide solution transferred on the substrate is 3%, because the concentration of such polyimide solution...
