Liquid crystal display panel and manufacturing method thereof

Abstract

The invention discloses a liquid crystal display panel and a preparation method thereof. The preparation method comprises the following steps of: S1: forming a first polaroid (1) on the first lateral face of an LCD (Liquid Crystal Display) layer (2) in an injection molding manner; and S2, forming a second Polaroid (3) on the second lateral face of the LCD layer (2) in the injection molding manner, so as to obtain the liquid crystal display panel combining the first polaroid (1), the LCD layer (2) and the second polaroid (3) into a whole body. The liquid crystal display panel comprises the first polaroid (1), the LCD layer (2) and the second polaroid (2), which are integrally combined. The liquid crystal display panel comprises the beneficial effects that an adhesive layer is eliminated, and the polaroids are arranged on the surface of the LCD layer; the influence on the light of the glue layer can be overcome due to the removal of the glue layer, so that the imaging color of the liquid crystal display panel is full; the manufacturing cost is lower, and the production efficiency is high; and the thickness of the liquid crystal display panel is reduced.

Description

technical field [0001] The present invention relates to a display panel, more specifically, to a liquid crystal display panel and a preparation method thereof. Background technique [0002] Now there are small and medium-sized liquid crystal display panels on the market (such as mobile phone, tablet, MP4, PDA and other mobile device liquid crystal display panels) composed of a lower polarizer, an LCD layer and an upper polarizer, and the upper and lower polarizers are respectively attached to the LCD layer. Upper and lower sides. The light coming from the backlight of the LCD layer becomes polarized light in a single direction after being polarized down. After the polarized light passes through the LCD layer, the light direction of the light passing through the LCD layer is determined by the liquid crystal molecules inside the LCD layer. Only the light whose direction of light is parallel to the polarization direction of the upper polarizer can pass through the upper polari...

AI Technical Summary

Problems solved by technology

However, in the above-mentioned bonding process, it is easy to bring in foreign matter, thereby causing the LCD layer to be stained, and the liquid crystal display panel produced in this way has defects such as bright spots and white spots when it is used.

In order to clean the foreign matter between the polarizer and the LCD layer, the polarizer needs to be removed and replaced with a new polarizer, but dismantling the polarizer will easily cause the LCD layer to break, which will also increase the production cost

In addition, the two layers of adhesive layers introduced in the bonding process have no other function except for bonding the polarizer to the surface of the LCD layer; the existence of the adhesive layer not only affects the transmission of light, As a result, the imaging color of the liquid crystal display panel is not full, and the thickness of the liquid crystal display panel is also increased, which is unfavorable for the development of electronic equipment in the direction of ultra-thin; at the same time, the additional two layers of adhesive layers also increase the production cost and reduce the Production efficiency of LCD panels

[0004] To sum up, the liquid crystal display panel in the prior art has the defects of high production cost, low production efficiency, the adhesive layer affects the transmission of light, and the adhesive layer also increases the thickness of the liquid crystal display panel.
