Accompanying drawing explanation
Figure 1 shows that the schematic diagram of the cover plate of existing a kind of capacitive touch screen;
Figure 2 shows that the schematic diagram of the capacitive touch screen that the utility model provides;
Wherein, the cover plate of 10-capacitive touch screen, 11-glass substrate, 12-second printing ink layer, 13-second solid state optics glue-line, 20-capacitive touch screen, 21-cover plate, 23-first solid state optics glue-line, 25-sensor layer, 120-second visible area, 210-substrate, 212-first printing ink layer, 214-transparent ink layer, 216-first visible area.
Embodiment
For further setting forth the utility model for the technological means reaching predetermined utility model object and take and effect, below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in detail as follows.
Figure 2 shows that the schematic diagram of the capacitive touch screen 20 that the utility model provides.As shown in Figure 2, capacitive touch screen 20 of the present utility model comprises cover plate 21, first solid state optics glue-line 23 and sensor layer 25 (Sensor) from top to bottom successively.
Wherein, the first solid state optics glue-line 23 is a two-sided mucigel, its upper and lower two surfaces respectively with cover plate 21 and the adhesion of sensor layer 25 phase.
Sensor layer 25 can be the sensor layer of single layer structure, also can be double-deck sensor layer.The sensor layer of single layer structure, by forming different patterns on individual layer ito thin film, realizes the determination of coordinate in X, Y-direction.Double-deck sensor layer is then by forming X respectively to the wire with Y-direction on two-layer ito thin film, makes it intersect the mode of rear formation X/Y matrix, realizes the determination of coordinate in X, Y-direction.
Cover plate 21 comprises substrate 210, first printing ink layer 212 and transparent ink layer 214.Wherein, substrate 210 can be glass substrate or pet substrate (being glass substrate under normal circumstances), and it has two relative surfaces.The ink that first printing ink layer 212 adopts is common band color ink.First printing ink layer 212 is formed at the edge on one of them surface of substrate 210, hollow out in the middle part of it and make the first printing ink layer 212 projection over the substrate 210 in " mouth " character form structure, forms the first visible area 216 at the middle part of substrate 210.The ink that transparent ink layer 214 adopts is transparent gloss oil, and this light main body of oil is synthetic resin and solvent.Transparent ink layer 214 is filled in the first visible area 216, the equal and opposite in direction of its size and the first visible area 216, and its thickness is equal with the thickness of the first printing ink layer 212, make its lower surface (namely away from the surface of substrate 210) mutually concordant with the lower surface of the first printing ink layer 212.Understandably, transparent ink layer 214 of the present utility model also can be formed by other suitable transparent ink.
This cover plate 21 during fabrication, is first coated with printing-ink at one of them marginal surface of substrate 210, thus forms the first visible area 216 at the surface middle part of substrate 210, then in the first visible area 216, fill transparent ink.Like this, after transparent ink drying, namely in the first visible area 216, form transparent ink layer 214 and obtain cover plate 21 of the present utility model.
In sum, the ink step that the utility model is eliminated on substrate 210 by filling transparent ink in the first visible area 216, thus improve the production of the first edge, visible area 216 bubble when using solid state optics glue laminating, and then promote binding yield, reduce cost of products.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solutions of the utility model content, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
