Description

The display protection of high light transmittance ratio transparent resin and use the LCD of this screen
Technical field:
The utility model is relevant with LCD (LCD) protection screen, pastes before special and the panel of LCD and the display protection of the high light transmittance ratio transparent resin that prevents the reflection of display screen panel light, raising LCDs light transmission rate and display screen is shielded of assembling 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) learns, the LCD device be by backlight with the light that sends during by polaroid and liquid crystal cell, the device of control projection intensity recognition image.The brightness by liquid crystal cell (transmittance of LCD screen) and color film CF light (transmittance of CF) and backlight is depended in the brightness of LCD just.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; have at resin layer surface and utilize colloidal sol---gel method depositing Ti O2 or Nb2O5/SiO2 are anti-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; the surface is prone to rainbow, and basic change does not also take place for protection screen or diaphragm so far, and particularly reflectivity is less than 1%; printing opacity is more optimized low practical technique and the protection screen material of industrialization cost that reaches more than 97% and is not also had appearance greater than 93%.
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 that to watch face light reflectivity, protection display not to be scratched and resist damages, adopt the coating technique of low-cost high-efficiency and film simultaneously be the display protection of the high light transmittance ratio transparent resin of production.Another purpose of the present utility model is for a kind of LCD of using this protection screen is provided.
