One side of the substrate is compounded with TiO <2> layer/SiO <2> layer, or an antireflection reflected film layer with two layers of Nb<2> O<5> layer/SiO<2> layer, or compounds TiO <2> layer / SiO <2> layer, or a multilayer antireflection reflected film layer of Nb<2> O<5> layer / SiO<2> layer in an overlapping way, which form a two-layer film layer of TiO <2> layer / SiO <2> layer, or a two-layer film layer of Nb<2> O<5> layer / SiO<2> layer, or a multi-layer overlapping film layer of TiO <2> layer / SiO <2> layer, or a multi-layer overlapping film layer of Nb <2> O <5> layer / SiO <2> layer in order from the substrate to outside. The other side of the substrate is compounded a heat with at least a function of scratch resistance, anti-static or anti-fogging antireflection and/or a photo curing acrylic resin bed. The protection screen of the utility model can decrease the reflectivity, can improve the light transmission rate and the effect of the optical images, greatly reduce the cost, and can fully improve the impact resistance damage capability, to make the protection screen become a secure protection screen. The utility model also provides a liquid crystal display using the glass protection screen.
Description
Technical field:
The utility model is relevant with LCD (LCD) protection screen, before special and the panel of LCD assembling prevent the reflection of display screen panel light, raising LCDs light transmission rate and the surface that display screen shields is had anti-caking mist function high transmission rate the display glass protection screen and use the LCD of this protection screen relevant.
Background technology:
The principle of work of LCD (LCD is to call LCD in the following text) is learnt, the LCD device is with the light that sends during by polaroid and liquid crystal cell by backlight, the device of control projection intensity recognition image, the brightness of LCD just depend on the brightness by liquid crystal cell (transmittance of LCD screen) and color film CF light (transmittance of CF) and backlight.Therefore, raising LCD surface brightness and save on backlight source power improve back light source brightness simultaneously and mainly set about from following several respects: the one, improve back light source brightness, the 2nd, improve the TFT aperture ratio of pixels, the 3rd, the brightness that improves all material, also promptly increase the transmittance of material as far as possible, improve the main at present prismatic brightness film that adopts of back light source brightness and increase emission brightness with adopting the novel lamp light source and improving reflection potential; The brightness that improves all material improves the raising that the LCD surface brightness also is the transmittance of a top protection screen of important channel, particularly display screen or diaphragm.Main at present acrylic sheet (PMMA resin sheet) or the polyester film sheet (BOPET diaphragm) of adopting of top protection screen of LCD display or diaphragm.Because though resin sheet material transmittance can be up to 90% and surface-brightening, but the reflectivity single face reaches more than 4%, two-sided stack can reach more than 8%, and damage resistant not, so all do non-glare treated at present on the surface of resin sheet, light reflectivity can be dropped to below 1%, and the surface can the above scuffing of anti-pencil test hardness 2H.Because non-glare treated is resin light reflecting surface to be treated to the light scattering surface reduce light reflectivity; therefore protection screen and the actual visible light transmissivity of diaphragm that obtains no longer is more than 90%; majority all drops to about 80% even lower; the brightness of backlight emission improved by various measures and cost expenditure before display screen, present a few percent to percent ten that overall transmitance is only arranged at last, but again this transmittance has been beaten nearly 20% even more discount for anti-dazzle antireflection because of protection screen or diaphragm.(because of its material only have 80% in addition the lower filter of seeing through).Therefore; at the reflectivity that reduces panel and protection screen; increase the skin hardness scratch resistance but improve the transmittance of protection screen or diaphragm again and be everybody pursuit always the physics and the mechanical protection performance of display screen; the surface reflectivity that particularly adopts which kind of technical scheme to reduce the protection screen material has multiple scheme to continue to bring out all the time, has at resin layer surface and utilizes colloidal sol---gel method depositing Ti O

2Anti-reflection anti-reflection rete; also have and utilize surperficial dip-coating organosilicon anti-reflection layer; but because thickness is wayward; transmittance only can reach about 92%, and yield rate is not high, and the surface is prone to rainbow; so far basic change does not also take place in protection screen or diaphragm; particularly reflectivity is less than 1%, and printing opacity is more optimized low practical technique and the protection screen material of industrialization cost that reaches more than 97% and also do not had appearance greater than 93%.If adopt the glass material protection screen in the display pannel front; or watch the surface to be coated with the protection screen of anti-reflection antireflection film layer; because this protection screen and display pannel be the spacing distance for display pannel anticollision damage existence is protected when assembling; because of not being is pasted together to have air interface; bigger at ambient humidity; temperature is lower; certain temperature rise is arranged during the LCD start; can cause a glass protection screen surface relative to produce the knot mist of short time because of the temperature difference and humidity reason with display pannel; so just having produced the glass and the film plating substrate that utilize high transmission rate replaces resin sheet may produce the technological difficulties (because of resin substrate can not produce knot mist phenomenon) of knot mist; for the coated glass protection screen with the antiradar reflectivity of high transmission rate is used for LCD display, must there be technical scheme to handle this difficult problem.
The utility model content:
The purpose of this utility model is in order to overcome above deficiency, provides a kind of and can improve display brightness, reduces and watch face light reflectivity, protection display not to be scratched and resist damages, adopt the coating technique of low-cost high-efficiency and surface that film is production to have the display glass protection screen of the high transmission rate of anti-caking mist function simultaneously.Another purpose of the present utility model is for a kind of LCD of using this protection screen is provided.
The purpose of this utility model is achieved in that
