Description
Technical field the present invention relates to a kind of assembly of LCD, relates in particular to a kind of Polarizer and the liquid crystal display that uses this Polarizer.
Background technology polaroid (polarizer) is one of significant components of liquid crystal indicator (LCD), and it is a kind of optical thin film with generation polarized light function that is composited by the layer high molecule material.As shown in Figure 1, polaroid is fitted in the two sides of liquid crystal cell 4, is referred to as polaroid 01 (or claiming the transmission sheet) and following polaroid 02 (or claiming reflector plate) respectively, and its function is the polarization of lightization with backlight.Liquid crystal indicator is through changing the electric signal of liquid crystal layer in the liquid crystal cell; Make the liquid crystal molecule of liquid crystal layer produce the optical channel that twisted arrangement formation has certain windup-degree; When polarized light passed through optical channel, its conducting amount and the amount of ending were controlled, thereby demonstrate painted picture.
General last polaroid structure is a sandwich structure at present, and is as shown in Figure 1, is made up of two- layer protection tunic 04,05 and middle one deck light polarizing film 03.Wherein, light polarizing film 03 is processed for polyvinyl alcohol material stretches through dyeing, and its performance has determined polarizing properties, the transmitance of polaroid, also is to influence polaroid color harmony optical durability simultaneously.The light polarizing film of processing owing to polyvinyl alcohol (PVA) 03 is prone to suction, fades and lose polarizing properties; Therefore need respectively use one deck optical homogeneity and transparent excellent protection tunic 04,05 to completely cut off moisture and air and protect light polarizing film on its both sides, described protection tunic 04,05 general cellulose triacetate (TAC) film that uses.If adopt protection tunic to can be made into anti-ultraviolet type polaroid and anti-dazzle type polaroid with ultraviolet isolation (UV CUT) and anti-dazzle (Anti-Glare) function.Polaroid is fitted on the glass of liquid crystal cell 4 41 and has just formed LCD device.
Along with various liquid crystal indicators; Particularly the utilization of large-screen liquid crystal display television more and more widely; People to liquid crystal display increasingly high technical requirement has been proposed, visual sense of beauty requires and cost requirement, for example ultra-thinization of outward appearance aspect claimed structure, no frameization, the magnificent light of panel; Aspect practicality, require anti-humidity and shock resistance; Aspect optical characteristics, require to improve contrast, reduce the luminous flux loss; Along with the utilization of 3-D technology on the liquid crystal indicator, liquid crystal display also needs to show the degree of depth level effect of image frame; On the other hand, people require the manufacturing cost of liquid crystal display more and more lower.Polaroid is especially gone up the correlated performance that polaroid is directly connected to liquid crystal display as ingredient important in the liquid crystal display.Polaroid of the prior art can not satisfy these technical requirements fully, is embodied in:
1, if with the polaroid of cellulose triacetate film as the protection tunic, (permeability is about 300g/m because the protection tunic still has certain moisture permeability
2/ day), its protective capability is slightly not enough under hot and humid situation;
2, the surperficial scratch resistance ability of protection tunic is after being coated with one deck scratch resistance coating (hard coat layer); Can reach the highest 3H in theory; But because polaroid is a flexible material; Thickness is generally about 300 μ, directly is attached on the glass of fragile liquid crystal cell, and polaroid does not have enough rigidity to realize the scratch resistance requirement that intensity is higher;
3, because polaroid is made up of flexible material, do not protect the function of liquid crystal cell, when liquid crystal display receives external force collision or pressurized when excessive, liquid crystal cell very easily damages;
4, as shown in Figure 2, disturb in order to prevent ambient light, the exiting surface of the protection tunic 04 of polaroid adopts pitted skin to handle to reach antiglare effect (Anti-Glare) usually.This pitted skin is handled has dual character, though reached the purpose of disperseing external interference light, the light that also liquid crystal cell is sent has simultaneously produced peptizaiton, has reduced the contrast performance of liquid crystal display.
Had at present to display appearance structure and security aspect improved " hard screen " technology to begin utilization, realized not having characteristics such as frame, magnificent and shock resistance such as display surface.As shown in Figure 3; Only just on original liquid crystal display, increased by a floor height passes through hard material 06 to this hard screen 09; Like organic glass (acrylic board), printing black surround glass etc.; Need to attach on two faces of high hard material 06 thoroughly and go up protection tunic 07, the hard screen 09 of this relatively independent interpolation does not relate to the basic structure of the liquid crystal display that is made up by polaroid.Because have the slit between screen 09 and the liquid crystal display firmly, the polarized light that liquid crystal display sends can produce birefringence and internal reflection at the place, slit, thereby directly influences the quality of display frame.As a kind of improvement, between the polaroid 01 of this hard screen 09 and liquid crystal display, inject leaded light resin 08, this method has solved the disadvantage that adopts the birefringence that this " hard screen " bring, but has increased manufacturing process difficulty and cost.

2, the moisture vapor transmission rate of glass substrate is little, even under the environment of HTHP, also can play protection effectively to polyvinyl alcohol film;
3, because each layer of polaroid very frivolous and arrived enough intensity all uses the liquid crystal indicator of this Polarizer can adopt no frame structural design;
4, emergent ray makes the horizontal visible angle of liquid crystal indicator enlarge through the refraction action of glass substrate in the hard screen polaroid;
5,, improved the degree of depth stereovision effect of image frame effectively, for 3-D technology utilizes the condition created more fully owing to the internal reflection characteristic of glass substrate;
