Abstract

The making process of protective antireflecting constituent includes the step of: cleaning glass; coating titanate solution films onto the two sides of the glass through soaking the glass inside ethyl titanate solution, stoving to eliminate water andethanol of the titanate solution films and form homogeneous titania films; coating silicic acid sol films by soaking the glass with titania films in ethyl silicate solution, stoving to eliminate water and ethanol to form homogeneous silica films.

Description

Technical field

[0001] The invention relates to a method for making an anti-reflection protective layer used in projection screens. Background technique

[0002] The screens currently used in projection TVs are generally composed of three layers (see Figure 1). The layer facing the projector is the Fresnel lens layer 1', and the middle layer is the inaccessible surface guide layer or scattering layer 2. ', the front surface is an anti-reflection protective layer 3'. Among them, the anti-reflection protective layer is also called the anti-reflection protection component, which mainly overcomes the reflection of ambient light, improves the contrast of the image, and protects the original microstructure of the middle layer from being artificially damaged.

[0003] At present, the production methods of anti-reflection protective layer (i.e. anti-reflection protection component) are as follows:
