Problems solved by technology

[0005] The present invention provides a display panel and a preparation method thereof, in order to solve the problem that in the existing display panel, since the PS membrane column is set on the PFA membrane layer, the PFA membrane layer collapses or rebounds under pressure, thereby affecting the upper layer of the display panel. The normal elastic range of the PS membrane column will cause bubbles to appear in the product under high altitude and low pressure environment, which will affect the technical problem of product yield.

Embodiment Construction

[0027] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0028] The present invention is aimed at the existing display panel. Since the PS film column is set on the PFA film layer, the PFA film layer collapses or rebounds under pressure, thereby affecting the normal elastic range of the PS film column on the upper layer, thereby causing the product to be under pressure. Bubbles appear in a high-altitude and low-pressure envi...

Abstract

The invention relates to a display panel and a preparation method thereof. The display panel comprises a first substrate and a second substrate that are opposite, and a liquid crystal layer clamped between the first substrate and the second substrate, wherein a thin film transistor layer, a color resistance layer, a PFA layer, a first electrode layer and an isolation pad are arranged on the firstsubstrate in sequence, trenches are arranged on the PFA layer and the first electrode layer, and the isolation pad is in the trenches. Trenches are arranged in the PFA layer, and the isolation pad isarranged in the trenches rather than superposed on the PFA, so that the PFA layer is prevented from affecting elasticity of the isolation pad, and the display panel does not have bubbles in high attitude and low pressure environment.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a preparation method thereof. Background technique [0002] In liquid crystal display panels, in COA (Color Filter on Array, color filter integrated on the array substrate) products, a passivation protective layer will be covered on the color color resist, but the passivation protective layer needs to be processed through film formation, exposure, Developing, etching, stripping and other processes are formed. In the prior art, the PFA (Polymer Film on Array) process is used to replace the passivation protective layer. In addition to saving the film forming and stripping process, it can also make the color color resist surface Planarization provides a planarized surface, which is beneficial to the subsequent process. [0003] PS (Photo Spacer) film column is the key material used to fix and support the thickness of liquid crystal in the liquid crystal display...
