Description
The divisional application that the application is application number 201310205786.6, denomination of invention is the patented claim of " multifunctional and composite type blooming, flat-panel screens and electronic installation ", the applying date of original female case is on May 29th, 2013.
Technical field
The present invention about a kind of composite optical film with structuring base material, particularly have highlight, the blooming of self-diffusion and screening flaw function; Particularly about a kind of composite optical film for flat-panel screens.
Background technology
Flat-panel screens technology is applied generally in television indicator, computer monitor and hand-hold electronic device, such as, on the display of mobile phone, mobile Internet access device (MID, MobileInternetDevice) etc.Liquid crystal display (LCD) is a kind of flat-panel screens, and it uses the Liquid Crystal Module with pel array to produce picture.
Fig. 1 shows for traditional LCD display.Backlight liquid crystal display 10 comprises LCD MODULE 12, the planar light source formed with backlight module 14, and several blooming such as upper diffusion sheet 22, lower diffusion sheet 24 and brightness enhancement sheet 26 and 28 is inserted between Liquid Crystal Module 12 and backlight module 14.Liquid Crystal Module 12 comprises the liquid crystal be sandwiched between two transparency carriers, and control circuit, is used for defining two-dimensional array.Backlight module 14 provides the distribution of light of plane, a kind ofly extends backlight in a plane for light source or is marginal mode backlight as shown in Figure 1, and it provides linear light source 16 on the edge of light guide plate 18.Reflector plate 20 is used for guiding light to enter light guide plate 18 from linear light sorurce 16, makes light through the plane in the face of Liquid Crystal Module 12 top.These several bloomings of upper diffusion sheet 22, lower diffusion sheet 24 and brightness enhancement sheet 26 and 28 are by the light redistribution passed through or concentrate, can be directed and advance closer to LCD MODULE 12 normal to a surface with the light making to leave these several bloomings, be distributed in the plane domain of Liquid Crystal Module 12 with making uniform light, and there is relatively high normal light intensity.
Reduce the power consumption of LCD screen, thickness and weight and the demand of quality can be kept to increase gradually.Therefore, it is desirable to reduce the power consumption of backlight module, weight and thickness, be also hopeful the thickness reducing blooming piece.In the past, many liquid crystal display use two-layer brightness enhancement sheet (liquid crystal display as shown in Figure 1), it rotates around the axle perpendicular to diaphragm plane, so the groove of other membrane layer is relative to each other in 90 degree, light is so made to be aligned in two planes perpendicular to light output surface, may optical disturbance being produced between a glossy surface in two brightness enhancement sheet and another light or body structure surface, causing in display frame just like the vision product (i.e. the figure of bright dark staggered repetition) of interference ripple etc. not for asking.Come from interference ripple, physical imperfection, stain and uneven etc. not for producing and affecting the effect of vision, by using upper diffusion sheet by shade (diffusion sheet 22 such as above brightness enhancement sheet 26).
So far, in order to reduce the thickness of overall blooming piece in liquid crystal display, many technology all put forth effort on the quantity reducing blooming piece, reduce to three from four (blooming pieces 22,24,26 and 28 of such as Fig. 1).Generally speaking be that upper diffusion sheet 22 and brightness enhancement sheet 26 are combined into single mixed type diaphragm structure, then combine three-chip type structure with lower diffusion sheet 24 and brightness enhancement sheet 28.The display of this three-chip type structure is widely used in portable electric device and notebook computer.
But, for reducing the size of these products and reducing costs, the display industry optical texture that still a kind of size of demand is more frivolous and cost-effective compared with three-member type display, its can provide can highlight, the optical texture of self-diffusion and screening flaw function.
