Abstract
The utility model discloses a liquid crystal display (LCD). The LCD comprises an indium tin oxide (ITO) glass substrate and an auxiliary conductive layer, wherein the auxiliary conductive layer covers a lead area on the ITO glass substrate. According to the technical scheme, the auxiliary conductive layer is arranged on the lead area of the ITO glass substrate, so that ITO surface resistance is lowered to reduce a resistance difference between leads, improve the display uniformity of a screen and improve the display effect of the LCD screen.
Description
Technical field
The utility model relates to the display technology field, is specifically related to a kind of liquid crystal display.
Background technology
Conventional PMLCD(Passive Matrix LCD, passive matrix liquid crystal display), usually all be to use individual layer ITO(Indium Tin Oxides, the nano indium tin metal oxide) glass substrate, its surface resistance is between 10-100 ohm/mouth, and this surface resistance reduces along with the increase of ITO thickness.
Too thick ITO thickness can impact the display effect of LCD, and is low etc. such as doubled background image, transmitance, therefore must control ITO thickness.But control ITO thickness can make its surface resistance larger, and resistance difference is excessive between causing going between, and then causes that screen display is uneven, affects the display effect of lcd screen.
The utility model content
The utility model embodiment provides a kind of liquid crystal display, to solve the technical matters that resistance difference is large and screen display is inhomogeneous between the lead-in wire that ito surface resistance causes greatly among the existing PMLCD.
A kind of liquid crystal display comprises ito glass substrate, also comprises auxiliary conductive layer, and this auxiliary conductive layer covers the lead district on the described ito glass substrate.
The utility model embodiment adopts the technical scheme that auxiliary conductive layer is set in the lead district of ito glass substrate, reduces ito surface resistance, thereby can reduce the resistance difference between the lead-in wire, improves the screen display homogeneity, improves the display effect of lcd screen.
Description of drawings
Fig. 1 is the structural representation of the liquid crystal display that provides of the utility model embodiment.
Embodiment
The utility model embodiment provides a kind of liquid crystal display, can solve the technical matters that resistance difference is large and screen display is inhomogeneous between the lead-in wire that ito surface resistance causes greatly among the existing PMLCD.Below be elaborated.
Embodiment one
Please refer to Fig. 1, the liquid crystal display that the utility model embodiment provides comprises ito glass substrate 100, also comprises auxiliary conductive layer 200,100 lead district on these auxiliary conductive layer 200 covering ito glass substrates.
Described auxiliary conductive layer adopts a kind of in the following material: ITO-Cu(nano indium tin metal oxide-copper), Cr-Cu(chromium-copper), Cr(chromium), IZO-Cu(Indium ?oxide-copper), Mo-Al-Mo(molybdenum-Solder for Al-Cu Joint Welding).The thickness of described auxiliary conductive layer between 1000-5000 Ethylmercurichlorendimide (Angstrom, A), negative 10 meters that 1A equals 10.
The liquid crystal display that the utility model provides can obtain by the ito glass substrate with auxiliary conductive layer is carried out second etch.After the second etch, forming lead district has auxiliary conductive layer to cover on the ITO cabling, the structure that the V.A viewable display area does not have auxiliary conductive layer to cover.
The liquid crystal display that the utility model embodiment provides is preferably PMLCD, can be applied to the application scenarioss such as car-mounted display and the demonstration of ordinary consumption series products.
The liquid crystal display that the utility model embodiment provides, the surface resistance of its glass substrate can be down to 0.1-1 ohm/mouth from 10-100 ohm of the prior art/mouth, thereby so that the line resistance of walking of LCD display greatly reduce.Because surface resistance and walk the significant decline of line resistance, so that the resistance difference between each lead-in wire has dropped to is minimum, guaranteed the show uniformity of LCD display, in order to obtain good display effect; Simultaneously, can also reduce the power consumption of LCD display, the power consumption penalty that the cabling path loss causes can be less to original 1/20-1/100; In addition, present embodiment has reduced resistance by auxiliary conductive layer, and does not increase ITO thickness, can avoid the decline of the LCD display effect that the increase of ITO thickness causes.
Following table 1 has shown the decline situation of surface resistance of the liquid crystal display of dissimilar glass substrates.
Table 1
The below further describes the beneficial effect of the utility model embodiment.
If adopt traditional ito substrate glass, when wiring lead-in wire, often can only guarantee that the resistance difference between adjacent two cablings is less, for example, such as for 10 ohm/mouthful glass substrate, the resistance of general adjacent traces can be controlled at about 0.1 Europe; But, when lead-in wire when more, for example during 200 com lines, although the difference that can guarantee adjacent two lead-in wires is about 0.1 ohm, but the difference of distant lead-in wire just may reach about 10 ohm, and this show uniformity on PMLCD has fatal impact.
If the liquid crystal display that adopts present embodiment to provide, because surface resistance is below 1 ohm/mouthful, the precision that then connects up can control to below 0.01-0.05 Europe, it is less to add cloth line resistance own, and loss is less, therefore, voltage basic difference in every wiring is little, therefore guaranteed the show uniformity of PMLCD, simultaneously because ito thin film is also thinner, guaranteed that LCD shows to have good display effect.
More than liquid crystal display that the utility model embodiment is provided be described in detail, but the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof, should not be construed as restriction of the present utility model.Those skilled in the art are in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
