In the touch stage, the multiplexing electrode in the multiplexing electrode in the first transparent electrode structure 40 and the second transparent electrode structure 50 is used as touching drive electrode and touch sensible electrode respectively, and bearing of trend is perpendicular to one another;
In the display stage, the multiplexing electrode in the multiplexing electrode in the first transparent electrode structure 40 and the second transparent electrode structure 50 is used as grating electrode and public electrode respectively.
On the basis of traditional raster box, touch-screen is embedded in this raster box, compared with traditional processing technology, corresponding figure can be made respectively on a pair underlay substrate, realize different functions in touch stage and display stage raster box, be combined into same block graphics by the touch figure of Presentation Function and the figure of three-dimensional display function, the complicated technology making figure respectively can be reduced, can also reduce by a pair underlay substrate, thus save material and processing cost.Meanwhile, embedded structure under the prerequisite of thinning integral thickness, can possess the function of touch and stereo display.
Optionally, in the present embodiment, the first transparent electrode structure 40 comprises multiplexing electrode 41 and the first electrode 42; First electrode 42 is used as public electrode in the display stage, is used as touch signal white space in the touch stage.Preferably, in the first transparent electrode structure 40, the width of the first electrode 42 is greater than the width of multiplexing electrode 41, and in the first transparent electrode structure 40, the first electrode 42 and multiplexing electrode 41 spaced apart.As shown in Figure 5, multiplexing electrode 41 is used as public electrode in the display stage to the floor map of the first transparent electrode structure 40 on first substrate 10, is used as touching drive electrode in the touch stage; And between multiplexing electrode 41, also there is the first electrode 42 that width is greater than multiplexing electrode 41, first electrode 42 is also used as public electrode in the display stage, but be used as touch signal white space in the touch stage, can prevent from too closely causing interference to touch signal each other owing to touching drive electrode distribution.Multiplexing electrode 41 on first substrate 10 and the first electrode 42 are all along the parallel distribution of long side direction of first substrate 10.Multiplexing electrode 41 and the first electrode 42 by row or column distribution, distribute as shown in Figure 5 by row, the corresponding multiplexing electrode of odd line signal line wherein, and corresponding first electrode of even line signal line, the width of the first electrode is greater than multiplexing electrode.
It should be noted that, the distance between multiplexing electrode 41 adjacent in the first transparent electrode structure 40 is relevant to the touch resolution designed in advance, if want to realize higher touch resolution, needs to reduce the distance between multiplexing electrode 41; Otherwise, if want to realize lower touch resolution, need to increase the distance between multiplexing electrode 41.
