Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the diffusion film or diffusion plate of the existing liquid crystal display optical film group adopts organic materials, and the temperature characteristics mainly depend on the material properties, which are easily deformed in high and low temperature environments and affect the optical properties of the diffusion film. Invented a method for preparing a high-reliability liquid crystal display diffusion plate using flat glass as the substrate and glue as the film material

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as Figure 1-2 shown.

[0021] A preparation method for a high-reliability liquid crystal display diffuser plate, which comprises the following steps:

[0022] First, use flat glass as the substrate; the flat glass should be glass commonly used in the display industry;

[0023] Secondly, evenly apply glue on the glass substrate according to a certain graphic design ("I" type, double "Y" or fish bone type, etc.); the glue can be one-component silica gel, epoxy glue or UV glue. One, several combinations of multi-component glue can also be used. There is no special requirement for the proportion of each component when there are multiple components. It is best to remove the air bubbles in the glue by vacuum, centrifugation or a combination of the two before use.

[0024] Third, stick the diffusion film on the glue, and apply press...

Abstract

A manufacturing method for a diffusion plate used for a high-reliability liquid crystal display is characterized in that firstly, plate glass is adopted as a substrate; secondly, the substrate is coated with glue evenly or according to a certain pattern design (I-type patterns, or double-Y-type patterns or fishbone-type patterns or others); thirdly, a diffusion film is attached to the glue, and pressure is exerted to enable the space between the diffusion film and the substrate to be covered with the glue; fourthly, the glue is solidified on the substrate, so that a glue layer is formed on the substrate and is reliable in gluing; finally, after the glue is solidified, the diffusion film is uncovered, the light evening function of the diffusion film is copied to the glue layer, and therefore the glass substrate is changed to be the diffusion plate with the light evening capacity. The manufactured diffusion plate has the advantages of being wide in temperature range, high in anti-impact and anti-vibration capacity, moisture-proof and heatproof capacity and reliability and the like.

Description

technical field [0001] The present invention relates to a liquid crystal display technology, in particular to a method for manufacturing a diffuser plate for liquid crystal display, in particular to a method for preparing a diffuser plate for liquid crystal display with high reliability using flat glass instead of organic materials as the base plate of the diffuser plate . Background technique [0002] As we all know, reinforced liquid crystal displays are widely used in outdoor, vehicle, ship, aerospace and other fields due to their high reliability. Due to the strengthening of the working environment of the liquid crystal display, its working performance requirements are more stringent than those of ordinary civilian liquid crystal display modules, and it must be able to adapt to harsh environments such as strong vibration, high humidity, high temperature, and low temperature. [0003] The diffusion film is an important part of the optical film assembly of the liquid cry...
