Description
Technical field
The present invention relates to a kind of display device, particularly a kind of liquid crystal indicator.
Background technology
Nearly ten years, lcd technology has been obtained develop rapidly, liquid crystal display is with characteristics such as it are light, thin, low in energy consumption, image quality is good, not only in fields such as portable set, desktop computers, occupy dominant position, and also replaced traditional kinescope TV fully and become the main flow in market at TV domain.
The TFT LCDs is a kind of display device of thin type, and it forms (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 surrounding sealing has formed the box-like seal of a flat.Etching rear on glass in the TFT LCDs has many TFT devices, and the drain D of each TFT is connected to the conduction region of rear certain area on glass, as pixel electrode.To couple together with the grid G of the TFT device on a line pixel, form column electrode (scan electrode); The source S of the TFT device on 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 through after Polarizer, become the polarized light with certain polarization direction.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, demonstrates corresponding color; The electric field intensity difference, the deflection angle of liquid crystal molecule is also different, and the light intensity seen through is different, and the brightness of demonstration is also different.The combination of the different light intensity by three kinds of colors of RGB shows motley image.
Because liquid crystal panel itself is not luminous, need backlight source module to provide light source for it.When light emits via backlight, not all light can pass panel.For example, the metal level signal wire of using to LCD source driving chip and grid drive chip, these places are except incomplete printing opacity, because be not subject to the control of voltage and can't show correct GTG through these local light yet, so, all need to utilize black matrix" (BM) to be covered, in order to avoid interfere with the correct brightness of other transmission regions, as shown in Figure 2.This just makes zone that can light-transmitting panel backlight greatly reduce (generally speaking, glazed area only has 50%), greatly reduces utilization ratio backlight.
Summary of the invention
Goal of the invention: for the problem and shortage of 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 achieving the above object, the technical solution used in the present invention is a kind of liquid crystal indicator, comprising:
One color membrane substrates;
Array basal plate, be oppositely arranged with described color membrane substrates;
One liquid crystal layer, be arranged between described color membrane substrates and described array base palte;
Described array base palte is positioned at backlight side, deviate from described array base palte on a side of described color membrane substrates and be provided with transparent material layer, the metal level signal wire place of the corresponding array base palte of described transparent material layer is provided with groove, can, by the incident ray deviation, avoid being stopped by the metal level signal wire.
For improving the utilization factor of material, reduce costs, described transparent material can be the planarization layer material in the array base palte processing procedure.
Described groove can, after the metal level signal wire completes, utilize the back-exposure mode to form.
For the light that major part was blocked originally can get around stopping of metal level signal wire, preferred, the width of described groove equates with the width of metal level signal wire.For making more light originally be blocked can get around stopping of black matrix", preferred, the width of described groove equates with the width of the black matrix" of described 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, be oppositely arranged with described color membrane substrates;
One liquid crystal layer, be arranged between described color membrane substrates and described array base palte;
Described color membrane substrates is positioned at backlight side, deviate from described color membrane substrates on a side of described array base palte and be provided with transparent material layer, the black matrix" place of the corresponding color membrane substrates of described transparent material layer is provided with groove, can, by the incident ray deviation, avoid being stopped by the metal level signal wire.
For improving the utilization factor of material, reduce costs, described transparent material can be the planarization layer material in the color membrane substrates processing procedure.
Described groove can, after black matrix" completes, utilize the back-exposure mode to form.
For the light that major part was blocked originally can get around, stop, preferred, the width of described groove equates with the width of described black matrix".
Enter human eye for stoping ambient light to shine the reflected light produced on the metal level signal wire, the side that described array base palte deviates from described color membrane substrates is provided with the rotatory polarization plate.
Beneficial effect: the present invention is by 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 by black matrix" get around stopping of black matrix", to improve transmitance backlight.Can, under equal power consumption, improve screen intensity like this; Perhaps, under equal screen intensity, reduce power consumption.
