AI Technical Summary

Problems solved by technology

However, because the film thickness is not easy to control, the light transmittance can only reach about 92%, and the yield is not high, and the surface is prone to rainbows. So far, the protective screen or protective film has not undergone fundamental changes, especially the reflectivity is less than 1%. Light is greater than 93%, more optimized to reach more than 97%, practical technology and protective screen materials with low industrialization cost have not yet appeared

Embodiment 1

[0031] Fig. 1 has provided present embodiment 1 figure. Referring to Fig. 1, the display protective screen 1 of high light transmittance transparent resin is made of a transparent transparent resin substrate 4 and a two-layer anti-reflection and anti-reflection TiO deposited sequentially by a vacuum magnetron sputtering method on one side of the substrate 4. 2 Coating 2 and SiO 2 The film layer 3 is formed, and the formation structure is SiO 2 / TiO 2 A display protective screen 1 of a transparent resin substrate with high light transmittance.

Embodiment 2

[0033] Fig. 2 has provided present embodiment 2 figure. Referring to Fig. 2, the display protective screen 15 of high light transmittance transparent resin is made of transparent transparent resin substrate 4 and adopts the TiO of two layers of antireflection and antireflection deposited successively by vacuum magnetron sputtering method on both sides of substrate 4 2 Coating 2 and SiO 2 The film layer 3 is formed, and the formation structure is SiO 2 / TiO 2 / Transparent resin substrate / TiO 2 / SiO 2 The display protective screen 15 of high light transmittance transparent resin. Two layers of anti-reflection and anti-reflection coatings are coated on both sides of the substrate 4, the light transmittance is greater than 94%, the double-sided superimposed reflectance is less than 2%, and the optimized thickness of the coating is: TiO 2 10~16nm, SiO 2 It is 90~120nm.

Embodiment 3

[0035] Fig. 3 has provided the figure of present embodiment 3, and present implementation is basically the same as embodiment 1, and difference is that on one side of substrate 4 and the TiO of antireflection and antireflection 2 An acrylic resin layer 17 that increases the hardness and light transmittance of the substrate is coated between the film layers 2, and the structure is SiO 2 / TiO 2 / Acrylic resin layer / Transparent resin substrate The display protective screen 16 of high light transmittance transparent resin. Coating a layer of acrylic resin can not only increase the light transmittance of the substrate by 1 to 2 percentage points, but also provide a surface hardness of more than 2H, so that the surface after coating has a pencil test hardness greater than 2H. At the same time, the formula can be adjusted to make the coating The adhesion between the layer and the substrate is greatly enhanced.

Abstract

The invention provides a high transmittance transparent resin display protection screen, comprising a transparent resin substrate, wherein, a double-layer antireflection filming layer of TiO2 and SiO2 or Nb2O5 and SiO2 is deposited in turn by adoption of the vacuum magnetron sputtering method on at least one surface of the transparent resin substrate, or a double-layer antireflection filming layer of TiO2 and SiO2 or Nb2O5 and SiO2 is overlapped and deposited in turn; a TiO2/SiO2 double-layer filming layer or a Nb2O5/SiO2 double-layer filming layer or a TiO2/SiO2 multilayered overlapped filming layer or a Nb2O5/SiO2 multilayered overlapped filming layer are formed in turn from the substrate to the outside. The protection screen of the invention can reduce reflectivity, improve transmittance and optical image effects, greatly reduce cost and fully improve the impact failure resistance of the display screen and become a safe protection screen. The invention also provides a liquid crystal display for the display protection screen.

Description

Technical field: [0001] The present invention is related to the protective screen of liquid crystal display (LCD), in particular to the high light transmittance transparency which prevents the light reflection of the display panel, improves the light transmittance of the liquid crystal display, and protects the display screen pasted and assembled in front of the liquid crystal display panel. The resin display protective screen is related to the liquid crystal display using the protective screen. Background technique: [0002] The working principle of liquid crystal display (LCD hereinafter referred to as LCD) is known. The LCD device is a device that controls the projection intensity to identify images when the backlight and the emitted light pass through the polarizer and the liquid crystal box. That is to say, the brightness of the LCD depends on the light passing through the liquid crystal cell (the light transmittance of the LCD screen), the brightness of the color filte...
