Abstract
The utility model discloses novel indium tin oxide (ITO) glass used for a capacitive touch screen. The novel ITO glass comprises the ITO glass used for twisted nematic (TN) and a top portion liquid layer which is arranged on ITO before printing of silver line in a pad printing mode to remove ITO bottom shadows. Compared with the prior art, the novel ITO glass used for the capacitive touch screen has the advantages of being low in cost and simple in counterpoint.
Description
Technical field
The utility model relates to the capacitive touch screen field, relates in particular the novel I TO glass that a kind of capacitive touch screen is used.
Background technology
Capacitive touch screen is the capacitance variations of utilizing the electrostatical binding between transparency electrode and the human body to produce, and the induced current that produces from position of touch detects its coordinate.The ito glass that is used at present capacitive touch screen all is to add to have plated the silicon dioxide restraining barrier under ITO; thereby so that the pattern of ITO film is not understood; but the expensive upper four times price of ito glass that this glass is used than general T N; in addition before product turnout; also to paste overleaf a slice diaphragm slightly larger than visible area; be PET+OCA glue, improved so especially production cost.
In view of this, the inventor has this case to produce for the defects further investigation of existing capacitive touch screen when producing then.
The utility model content
The novel I TO glass that provides a kind of capacitive touch screen to use is provided the purpose of this utility model, has into the high problem of product cost to solve prior art when producing capacitive touch screen.
In order to reach above-mentioned purpose, solution of the present utility model is:
The novel I TO glass that a kind of capacitive touch screen is used, wherein, this novel I TO glass comprise ito glass that TN uses and bat printing before the printed silver circuit on the ITO with the top liquid layer of shadow at the bottom of eliminating ITO.
Described top liquid layer is the silicon dioxide liquid level.
Described top liquid layer only is covered in the top of effective display area in the ito glass that TN uses.
After adopting said structure, the novel I TO glass that a kind of capacitive touch screen that the utility model relates to is used, the ito glass that it adopts TN to use, thus have the low characteristics of purchase cost; Because the ito glass that this TN uses does not form the top liquid layer in exposure and printing process, therefore can also see the ITO register guide, have contraposition and be easy to effect simultaneously.
Description of drawings
Fig. 1 is the structural representation that the utility model relates to the novel I TO glass that a kind of capacitive touch screen uses.
Among the figure:
Novel I TO glass 100
The ito glass 1 top liquid layer 2 that TN uses
Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As shown in Figure 1, the novel I TO glass 100 that a kind of capacitive touch screen that the utility model relates to is used, this novel I TO glass 100 comprises ito glass 1 and the top liquid layer 2 that TN uses, the ito glass 1 that this TN uses is this area ordinary articles, it is than capacitive touch screen special I TO glass, have the low characteristics of cost, this top liquid layer 2 before the printed silver circuit bat printing on ITO, thereby play the effect of eliminating shadow at the bottom of the ITO.
Particularly, described top liquid layer 2 is the silicon dioxide liquid level, and described top liquid layer 2 then only is covered in the top of effective display area in the ito glass 1 that TN uses.For FPC vertical pulling product, disappear first the shadow product in rear operation FPC nation regularly because can't see easily contraposition of ITO, and in the present embodiment, since top liquid layer 2 only bat printing above effective display area, the top liquid layer 2 that does not then have bat printing to play to disappear the shadow effect for FPC Bang Ding district is so have clearly effect of contraposition when deciding contraposition in FPC nation.
Like this, the novel I TO glass 100 that a kind of capacitive touch screen that the utility model relates to is used, because the ito glass 1 that this TN uses does not form top liquid layer 2 in exposure and printing process, therefore also in exposure and printing process, can see the ITO register guide, have contraposition and be easy to effect.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
Claims (3)
1. the novel I TO glass that capacitive touch screen is used is characterized in that, this novel I TO glass comprise ito glass that TN uses and bat printing before the printed silver circuit on the ITO with the top liquid layer of shadow at the bottom of eliminating ITO.
