Problems solved by technology

Similarly, the thickness of the high-refractive index layer is thicker, which increases the number of targets and vacuum chambers, and the process of continuous production is complicated and unstable.
[0019] In summary, although the prior art realizes the combination of anti-reflection and conductive film, there are still problems such as high cost, unstable process, and low yield in actual production. Difficulties, need to provide new design solutions

Abstract

A novel antireflection conductive film has three different specific structures. The conductive film comprises a high refractive index layer (H), a low refractive index layer (L), a transparent conductive film (T), and / or an intermediate refractive index film (M). Each layer of film is arranged according to the regulation of L / H / S / H / L / T type, or (L / H)<2> / S / (H / L)<2> / T type or L / M / H / S / H / M / L / T to form a multi-layer composite film. The thickness of each film layer of the novel antireflection conductive film according to the invention is smaller. The producing technique can be simplified and the invention is suitable for the continuous batch production and is especially suitable for producing antireflection conductive film with large area. The invention can be widely used as the antireflection film on optical glass or transparent plastic based material, and has a wide application in liquid crystal display, cathode ray tube, architectural glass, panel of touch screen, wave filter of screen and the like.

Description

technical field [0001] The invention relates to an anti-reflection conductive film attached to transparent materials, especially for anti-reflection films attached to optical glass and transparent plastic substrates such as liquid crystal displays, cathode ray tubes, architectural glass, touch screen panels, and screen filters. conductive film. Background technique [0002] When a display device such as a cathode ray tube or a liquid crystal display is used in a bright outdoor public place, the external light has a great interference on the display screen, especially for some liquid crystal display (LCD), the human eye can hardly distinguish the displayed color normally. Ratio and contrast, so that this type of display can not play a normal display effect, such as the LCD screen of a mobile phone can hardly see the displayed content in the sun. [0003] The following two methods can be used to solve this problem, one is to reduce the light loss rate of the various component...
