Abstract
The invention relates to a novel STN liquid crystal display screen, and aims to avoid abnormal lighting when a screen is powered on. The novel STN liquid crystal display screen consists of two ITO (indium-tin oxide) glass plates, wherein a plurality of actual wires formed by photoetching and arranged in a criss-cross manner are formed in a graphic area on the inner surface of each of the two glass plates; the actual wires are connected with an external integrated circuit via electrode led-out areas of non-graphic areas around the graphic areas; a plurality of virtual wires formed by photoetching but not connected with the external integrated circuit are formed in each of the non-graphic areas. By optimizing wire arrangement, the vision effect of the display screen can be remarkably improved for people, and meanwhile abnormal lighting is also prevented.
Description
Technical field
The invention belongs to STN LCDs field, particularly relate to a kind of novel stn liquid crystal display screen.
Background technology
It is known that, STN (super-twist nematic) display owing to occurring on domestic market is only needing the region showing figure to carry out photoetching, ITO (pluging with molten metal tin-oxide) floor is rejected the most completely in non-graphic district, and the glass coating ITO has the biggest difference with the light glass colour not coating ITO, when causing screen not lighted, centre has the region of figure and surrounding not to have the region background color of figure inconsistent, thus have impact on the visual effect of display screen.Additionally, owing to LCDs is to modulate light to show image by row electrode and row electrode overlap action liquid crystal in glass case, row electrode and row electrode must lead to external circuit respectively from two blocks of glass, the lead-out wiring of electrode extends laterally away at once, the lead-out wiring of row electrode is longitudinally drawn, the lead-out wiring of electrode must pass non-display area, therefore in screen surrounding non-graphic region, such region necessarily occurs, the electrode lead-out area in i.e. ITO glass non-graphic district there is also real wiring, in addition, other regions, non-graphic district are the light glass rejecting ITO floor completely.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of novel STN LCDs that can overcome graph area and the non-graphic district inconsistent defect of background color.The problems referred to above to be solved, the present invention includes two panels ITO glass plate, glass plate inner surface graphics field is contained by the real wiring of some be lithographically formed, real wiring must be connected to external integrated through surrounding non-graphic region, with the exception of this, also contain in non-graphic region by some be lithographically formed and the outside empty wiring being connected without circuit.
Owing to being connected without circuit with outside, therefore these circuits are referred to as void wiring.The corresponding wiring being connected with external integrated is referred to as real wiring.If empty wiring is dealt with improperly, it will occur that void wiring and empty wiring, empty wiring and connecting up in fact cause improper lights.The improper reason lighted is illustrated to as a example by real wiring by void wiring.If wherein the row void wiring of a glass sheets is across in the real wiring of row of another glass sheets, so be equivalent to capacitor due to liquid crystal cell, the real wiring of row being stacked in row void wiring is added with ac signal, these signals can pass through liquid crystal cell (being equivalent to capacitor), row void wiring (being equivalent to resistance) occurs crosstalk, when certain-voltage difference of the real wiring of bar row and empty wiring exceedes the threshold voltage of LCDs, then this Duan Lieshi wiring can be lit.In order to avoid the improper generation lighting phenomenon, must eliminate the formation in any loop when process void connects up, i.e. empty wiring can not connect up across the empty of reality wiring, two or more than two of two or more than two.Therefore as this reality
With novel improvement, when processing void wiring, the empty wiring in a glass sheets non-graphic district must be made to be contained among reality wiring (herein referring to non-graphic region electrode lead-out area) or the empty wiring (herein referring to non-graphic district except other parts of electrode lead-out area) in another glass sheets non-graphic district.
It provides the benefit that, by processing the optimization of wiring so that when screen is not lighted, whole screen all demonstrates identical background color, and when screen is lighted, non-graphic region also will not cause improper lighting because of circuit interference.

Detailed description of the invention
With specific embodiment, the present invention is elaborated below in conjunction with the accompanying drawings.
As shown in the figure, the present invention is made up of upper and lower two panels ITO glass plate 1,2, be lithographically formed capable real wiring 4 and the real wiring 5 of row in the graphics field 3 of the inner surface of upper and lower two panels ITO glass plate, the real wiring 4 of row wiring 5 real with row will be connected with external integrated through the electrode lead-out area 7,8 in non-graphic district 6.Also contain in non-graphic district 6 by some be lithographically formed and the outside empty wiring 9,10 being connected without circuit.
It is also shown in by figure, empty wiring 9 is not only had relative to bottom sheet glass plate electrode extension in upper glass sheets non-graphic district 6, and its trend should be consistent with the wiring 8 in fact of the row of bottom sheet glass plate electrode lead-out area, line width should be able to be contained in described reality wiring or coincide with, connect up a width of 60 microns strictly according to the facts, then empty cloth live width is not more than 60 microns.In like manner, lower glass sheets non-graphic district 6 relative on glass sheets electrode lead-out part divide and also have empty wiring 10, the wiring 7 real with the row of upper glass sheets electrode lead-out area of its trend is consistent, and width should be contained in during described reality connects up or coincide with.And except other parts of non-graphic district of electrode lead-out area, such as pure empty wiring area 11, the empty of upper and lower two glass sheets connects up
All moving towards identical, live width is essentially identical, will not occur improper to light phenomenon.
