Preparation method of liquid crystal cell

Abstract

The invention discloses a liquid crystal cell preparation method comprising the following steps of forming an orientation film on an array substrate and a color film substrate, coating sealing glue outside display areas of the array substrate and the color film substrate, instilling a plurality of liquid crystal drops on the orientation film of the array substrate or the color film substrate, the liquid crystal drops form a liquid crystal distribution map on the orientation film; the liquid crystal drops are arranged in an irregular shapes or a curve shape; the array substrate and the color film substrate are attached via the sealing glue; the sealing glue is solidified to form a liquid crystal box; and a Mura (ripple displaying) problem of the liquid crystal display device can be eliminated by the use of the liquid crystal preparation method.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a method for preparing a liquid crystal cell. Background technique [0002] Liquid crystal display devices have become the mainstream of display devices due to their advantages of low weight, small volume, and low energy consumption. The liquid crystal cell is the core component of the liquid crystal display device, and its quality plays a decisive role in the display effect of the liquid crystal display device. A liquid crystal cell generally includes an array substrate, a color filter substrate, and liquid crystal filled between the array substrate and the color filter substrate. Liquid crystal filling methods include vacuum injection and liquid crystal drop (ODF, One Drop Filling). The vacuum injection type is usually time-consuming, wastes liquid crystals, and has low mass production efficiency; while the filling method of the liquid crystal dripping type has the adva...

Problems solved by technology

However, when the liquid crystal is filled with the liquid crystal dropping method, the liquid crystal dripping on the array substrate or the color filter substrate is a drop of independent liquid crystal drop, and the liquid crystal drop spreads to the surrounding area, but because the liquid crystal in the central area of ​​the liquid crystal drop first contacts with the array substrate or The alignment film of the color filter substrate is in contact, and its alignment time is longer than that of the liquid crystal in the area around the liquid crystal drop, so some differences are prone to appear between the center area of ​​​​the liquid crystal drop and the area around the liquid crystal drop, resulting in Mura (display ripple) phenomenon

In the existing technology, the arrangement of liquid crystal droplets (referred to as "dot diagram") is usually a regular linear arrangement, please refer to figure 1 , figure 1 It is a schematic diagram of the distribution of liquid crystal drops in the prior art. The liquid crystal drops 10' on the array substrate or the color filter substrate 20' are arranged in a straight line in two directions perpendicular to each other, and the distances between the liquid crystal drops 10' are equal. This will make the environment of each liquid crystal drop 10' the same, and it is easy to make the direction of the above-mentioned differences of each liquid crystal drop 10' the same, and the liquid crystal drops on the same row or column will connect the above-mentioned differences into rows. Or row, so that the above-mentioned ripples are enlarged, and the human eyes can see these enlarged ripples, that is, the Mura phenomenon

In this way, it will adversely affect the display effect of the liquid crystal display device.
