Description
Technical field
The present invention relates to a kind of panel of LCD, relate in particular to a kind of panel of LCD of tool wide viewing angle.
Background technology
Active thin film transistor (TFT) (TFT-LCD) is to be used for the assembly of each pixel of ACTIVE CONTROL (pixel) light throughput, and the generation of its image is to allow each independent pixel on the panel can both produce the color of wanting.In order to reach this purpose, a plurality of cold cathode fluorescent lamp must be used as the backlight of display, and in order to allow light pass through each pixel, wicket or switch that panel must be cut apart and manufacture one by one allow light pass through.Therefore LCD (LCD) then is to use Liquid crystal module to come the screen of modulation light, and liquid crystal can change its molecular structure, can allow in various degree light quantity by itself (also can block light fully).Contain two Polarizers, colored filter array and alignment film in the LCD, they can determine the generation of the maximal value and the color of luminous flux.Liquid crystal layer is given both alignment layers when imposing a voltage between two sheet glass sheets, then produce an electric field, and the liquid crystal at both alignment layers interface is arranged towards some directions.Each pixel all is made up of three sub-pixels of red, green, blue (Subpixel), just as iconoscope.
The most general liquid crystal mode is twisted nematic liquid crystal TFT (TFT-Twisted Nematic at present, TFT-TN), its operation principles is that transistor applies zero volt voltage to sub-pixel, and liquid crystal (and their control the polarisation that passes through) horizontally rotates 90 degree in two substrates.Because the deflection filter disc of second substrate with respect to first be offset 90 the degree, so light can pass through it, if the sub-pixel of red, green, blue can fully be illuminated, they will mix and on picture the generation white point; If but apply a voltage to the indium oxide film (ITO) of tin dope, then can form a vertical electric field, it will destroy the helical structure of liquid crystal, liquid crystal molecule can be attempted and will himself be arranged in the direction identical with electric field, represent that like that liquid crystal molecule at last can be vertical with second filter disc, under this state, the deflection incident ray can't pass whole sub-pixel, the white point of sub-pixel has become stain, and whole image will present black.
Compare with traditional cathode ray tube (CRT) display and TFT-TN, TFT-TN has several great shortcomings, and one of them is the problem at visual angle.When certain angle is watched TFT-LCD, will find the rapid decline of brightness and the serious color offset phenomenon of display.TFT-TN has only the visual angles of 90 degree usually, and just therefore each 45 degree of a left side/right both sides, improve the visual angle and be always the problem that the effort of LCD industry will overcome.
At present, the wide viewing angle technology mainly can be divided into three major types: (1) optical compensation embrane method (TN+Film); (2) the multiregional vertical align method (Multi-domain Vertical Alignment, MVA); (3) transverse electric field effect method (In Plane Switching, IPS).Wherein method (2) and (3) relate to the processing procedure in the liquid crystal cell, and are comparatively complicated.And method (1) is the optical compensation embrane method, only needing to increase the subsides optical compensation films at existing TFT-LCD gets final product, it is the technology of easy application, and this technology is cheap than other two kinds of technology, qualification rate is also high, therefore present wide-angle liquid crystal display market, the method of main employing optical compensation films is main, accounts for 80% of whole market.
See also Fig. 1, it is a wide viewing angle LCD panel construction that method produced that utilizes aforementioned optical compensation films.Wherein this wide viewing angle LCD panel construction comprises: one first transparency carrier 11; One second transparency carrier 12; One is located in the liquid crystal layer 13 of 12 of this first transparency carrier 11 and this second transparency carriers; One is attached at first optical compensation films 14 of this first transparency carrier 11; And second optical compensation films 15 that is attached at this second transparency carrier 12.Certainly in practical application, said structure also comprises one first Polarizer 16, is attached at outside this first optical compensation films 14; And one second Polarizer 17, attach outside this second optical compensation films 15.Said structure also comprises one first alignment film 18, is attached in this first transparency carrier 11; And one second alignment film 19, be attached in this second transparency carrier 12.Wherein this first transparency carrier 11 is made by the glass substrate or the plastic base of an inextensibility with this second transparency carrier more than 12; This first Polarizer 16 and this second Polarizer more than 17 by a polyvinyl alcohol (PVA) (polyvinyl alcohol, PVA) film be located in two triacetate fibers (triacetyl-cellulose, TAC) made between the film; This first and second optical compensation films 14,15 then is responsible for providing the function that increases the contrast of LCD panel visual angle, and it can be promoted to the visual angle of LCD 100～140 degree.Therefore, optical compensation films, promptly (Wide View Film WVF) in the LCD industry, is quite crucial material member to view film.Because LCD is to utilize characteristic and the optical property of liquid crystal between solid and liquid, the collocation optical thin film manifests light and shade, the collocation of various optical thin films, the display quality that influence is final.Yet the whole world at present only Fuji description (Japanese trader) optical compensation films that increases the contrast of TFT-LCD visual angle is provided, the view film (FujiFilm) that Fuji's description is produced provides to light polarizing film production firm, by selling again to the TFT-LCD producer after the light polarizing film manufacturer applying, price is 2 to 3 times of the light polarizing film of no view film, not only cost raising, Production Time are elongated, and because the quality of each tame light polarizing film manufacturer applying view film is uneven, the therefore problem that when the light polarizing film of each tame different vendor of combination, easily causes qualification rate to reduce.
