Description
Technical field
The present invention relates to a kind of display device, particularly a kind of liquid crystal indicator.
Background technology
Over past ten years; Lcd technology has been obtained develop rapidly; LCD is with characteristics such as it are light, thin, low in energy consumption, image quality is good; Not only occupy dominant position, and also replaced traditional kinescope TV fully at TV domain and become the main flow in market in fields such as portable set, desktop computers.
The TFT LCDs is a kind of display device of thin type, and it constitutes (as shown in Figure 1) by the two blocks of clear glasses that are parallel to each other in front and back (substrate), has been full of liquid crystal between glass substrate, and the box-like seal of a flat has been formed in sealing all around.Etching back on glass at the TFT LCDs has many TFT devices, and the drain D of each TFT is connected to the conduction region of back certain area on glass, as pixel electrode.To couple together with the grid G of the TFT device on delegation's pixel, form column electrode (scan electrode); The source S of the TFT device on the same row pixel is coupled together, form row drive electrodes (data electrode).On the front glass of TFT LCDs, another electrode of the pixel that distributing.All these electrodes all link together, and form a path electrode, are called public (Common) electrode.
The light that backlight sends becomes the polarized light with certain polarization direction through the back Polarizer.Institute's making alive between the TFT control electrode, and this voltage acts on the polarization direction that liquid crystal is controlled polarized light, polarized light forms monochromatic polarized light after seeing through corresponding color film chromatograph, if polarized light can penetrate front polarizer, then demonstrates corresponding color; Electric field intensity is different, and the deflection angle of liquid crystal molecule is also different, and the light intensity that sees through is different, and the brightness of demonstration is also different.The combination of the different light intensity through three kinds of colors of RGB shows motley image.
Because liquid crystal panel itself is not luminous, needing backlight source module is that it provides light source.When light emitted via backlight, not all light can both pass panel.For example; The metal level signal wire of using for LCD source driving chip and grid drive chip, these places are except incomplete printing opacity, also because do not receive the control of voltage and can't show correct GTG through these local light; So; All need utilize black matrix" (BM) to cover, in order to avoid interfere with the correct brightness of other transmission regions, as shown in Figure 2.This just makes the zone that can see through panel backlight reduce (generally speaking, glazed area has only 50%) greatly, greatly reduces utilization ratio backlight.
Summary of the invention
Goal of the invention: the problem and shortage to above-mentioned existing existence the purpose of this invention is to provide a kind of liquid crystal indicator that improves transmitance backlight.
Technical scheme: for realizing the foregoing invention purpose, the technical scheme that the present invention adopts is a kind of liquid crystal indicator, comprising:
One color membrane substrates;
Array basal plate is oppositely arranged with said color membrane substrates;
One liquid crystal layer is arranged between said color membrane substrates and the said array base palte;
Said array base palte is positioned at backlight side; Deviate from said array base palte on the side of said color membrane substrates and be provided with transparent material layer; The metal level signal wire place of the corresponding array base palte of said transparent material layer is provided with groove, can the incident ray deviation be avoided being stopped by the metal level signal wire.
For improving the utilization factor of material, reduce cost, said transparent material can be the planarization layer material in the array base palte processing procedure.
Said groove can utilize the back-exposure mode to form after the metal level signal wire is accomplished.
For the light that major part was blocked originally can get around stopping of metal level signal wire, preferred, the width of said groove equates with the width of metal level signal wire.For making more light that blocked originally can get around stopping of black matrix", preferred, the width of said groove equates with the width of the black matrix" of said color membrane substrates.
The another kind of technical scheme that the present invention adopts is a kind of liquid crystal indicator, comprising: a color membrane substrates;
Array basal plate is oppositely arranged with said color membrane substrates;
One liquid crystal layer is arranged between said color membrane substrates and the said array base palte;
Said color membrane substrates is positioned at backlight side; Deviate from said color membrane substrates on the side of said array base palte and be provided with transparent material layer; The black matrix" place of the corresponding color membrane substrates of said transparent material layer is provided with groove, can the incident ray deviation be avoided being stopped by the metal level signal wire.
For improving the utilization factor of material, reduce cost, said transparent material can be the planarization layer material in the color membrane substrates processing procedure.
Said groove can utilize the back-exposure mode to form after black matrix" is accomplished.
, the light that major part was blocked originally stops that preferred, the width of said groove equates with the width of said black matrix" for can getting around.
The reflected light entering human eye that produces on the metal level signal wire for stoping ambient light to shine, the side that said array base palte deviates from said color membrane substrates is provided with the rotatory polarization plate.
Beneficial effect: the present invention is through increasing by a transparent material layer at array base palte dorsal part or color membrane substrates dorsal part; Over against the position of black matrix" spill microstructure (groove) is set at transparent material layer; Thereby make backlight can being scattered of originally being blocked get around stopping of black matrix", to improve transmitance backlight by black matrix".Can under equal power consumption, improve screen intensity like this; Perhaps under equal screen intensity, reduce power consumption.
