Abstract
The utility model belongs to the technical field of liquid crystal display and provides a COG (Chip On Glass) liquid crystal display device. The COG liquid crystal display device comprises an ITO (Indium Tin Oxide) glass substrate, an electrode film pattern and an LCD (Liquid Crystal Display) screen; a polyimide layer is printed on the top layer of a step of the LCD screen. According to the COG liquid crystal display device, the polyimide layer is printed on the top layer of the step of the LCD screen so that the height of the step of the LCD screen is the same as that of the polyimide layer in a box; when a product is rubbed, no step exists; after being rubbed, the top layer of the step of the LCD screen has no negative cross grain phenomenon so that the display effect of the LCD screen is guaranteed.
Description
Technical field
The utility model belongs to technical field of liquid crystal display, relates in particular to a kind of COG liquid crystal indicator.
Background technology
LCD screen, because displaying contents is abundant, power consumption is low, is widely used in industrial every field, and existing LCD screen is comprised of ITO, liquid crystal, polaroid or stitch; Under general environment temperature, can well show the various information of user's needs; Wherein the high way production difficulty of STN-LCD (COG) is large, and yield is lower.The twill that wherein rubs is bad is one of main factor affecting yield, especially the yield impact on STN-LCD (COG) GTG product.
In general, COG product can be in box, step terminal cabling region (unbundling region) stamps top layer, and step top layer protection terminal cabling is not corroded.The rubbing machine that adopts hair wheel not turn to, the groove that rubs out, during grappling liquid crystal molecule, there is the friction twill consistent with frictional direction in the top layer on terminal, when the energising of filling liquid crystal is lighted, deep mixed the causing that LCD shows.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of COG liquid crystal indicator is provided, and the problem of twill appears in its step top layer that has solved LCD display when friction.
The utility model is achieved in that a kind of COG liquid crystal indicator, comprises ito glass substrate, electrode film pattern and LCD display, and the step top layer of described LCD display is printed with a polyimide layer.
Particularly, the size of described polyimide layer is greater than the size of the step top layer of described LCD display.
The utility model is by the step top layer printing polyimide layer in LCD display, make the step of LCD display consistent with the height of polyimide layer in box, when friction, there is not step in product, after friction, the step top layer of LCD display there will not be twill bad phenomenon, has guaranteed the display effect of LCD display.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the ito glass substrate that provides of the utility model embodiment and the schematic diagram of electrode film pattern.
Fig. 2 is the schematic diagram of the LCD display that provides of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As depicted in figs. 1 and 2, a kind of COG liquid crystal indicator that the utility model embodiment provides, comprise ito glass substrate 1, electrode film pattern 2 and LCD display 3, the step top layer of LCD display 3 is printed with a polyimide layer 4 (being PI layer), the size of polyimide layer 4 is greater than the size of the step top layer of LCD display 3, for example 0.5mm greatly.
The utility model is by the step top layer printing polyimide layer 4 in LCD display 3, make the step of LCD display 3 consistent with the height of polyimide layer (not shown) in box, when friction, there is not step in product, after friction, the step top layer of LCD display 3 there will not be twill bad phenomenon, has guaranteed the display effect of LCD display 3.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
Claims (2)
1. a COG liquid crystal indicator, comprises ito glass substrate, electrode film pattern and LCD display, it is characterized in that, the step top layer of described LCD display is printed with a polyimide layer.
2. a kind of COG liquid crystal indicator as claimed in claim 1, is characterized in that, the size of described polyimide layer is greater than the size of the step top layer of described LCD display.
