Problems solved by technology

[0005] When the TFT substrate is bonded to the CF substrate, it is necessary to form a sealant on the edge of the substrate to bond the upper and lower substrates. In the prior art, the sealant material is generally coated with a spray nozzle to seal the sealant on the substrate. In the formation of the plastic frame, the width of the plastic frame cannot be effectively controlled during the formation of the plastic frame. There are situations where the width of the plastic frame is different at different positions. Waiting for bad

Abstract

The invention provides a rubber frame manufacturing method and a display panel. The rubber frame manufacturing method comprises the following steps that S1, a first substrate is provided, wherein thefirst substrate comprises a first area and a second area surrounding the first area; S2, an internal retaining wall surrounding the first area and an external retaining wall surrounding the internal retaining wall are formed in the second area, wherein the internal retaining wall and the external retaining wall are arranged in a spaced way to form a gap between the internal retaining wall and theexternal retaining wall; S3, the gap is filled with a rubber frame material to form a rubber frame. The gap is formed by utilizing the internal retaining wall and the external retaining wall and is filled with the rubber frame material to form the rubber frame so that the width of the rubber frame can be effectively controlled, the adhesion power of the rubber frame can be ensured, and poor manufacturing process is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a plastic frame and a display panel. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal display devices 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 place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. The direction of the liquid crystal m...
