Description

The device of integrated parallax barrier and capacitance touch screen and comprise its display device
Technical field
The utility model belongs to stereo-picture display technique field, relates in particular to the device of a kind of integrated parallax barrier and capacitance touch screen and the display device that comprises this touch-screen.
Background technology
Three-dimensional (3D) image display device can be divided into two big classes substantially: glasses type stereoscopic display device and glasses-free type stereoscopic display device (automatic display device of stereoscopic image).Wherein used polarising glass, shutter glasses and red blue glasses etc. in the glasses type stereoscopic display device, the existence of glasses can cause the beholder to feel inconvenient and may cause ophthalmology disease.And glasses-free type stereoscopic display device only just can be appreciated stereo-picture by the direct viewing screen, therefore, currently studies over against automatic display device of stereoscopic image.
The 3 D image display method of glasses-free type stereoscopic display device includes lens method, holographic method and parallax barrier method etc.Because lens method and holographic method have the expense that complicated structure needs great number, therefore, they only are used for specific application.
Figure 1 shows that the stereo-picture displaying principle synoptic diagram that utilizes conventional parallax barrier.Routinely, parallax barrier can be directly and the two dimensional image display module fit fixingly, can realize that 3D rendering shows, so the parallax barrier Faxian shows that 3D rendering is simple in structure relatively, cost is low, be suitable for broad commercial applications.As shown in Figure 1,10 is two dimensional image display module (TFT-LCD (Thin Film Transistor-Liquid Crystal Display for example, Thin Film Transistor-LCD)), 20 is parallax barrier, and it places between beholder's the eyes and two dimensional image display module 10.In the parallax barrier display packing, the image that right and left eyes is seen shows that with the vertical pattern that replaces the several portions of this pattern is stopped by very thin vertical grid (being fence).By this way, the vertical pattern image that left eye is seen is separated by fence with the vertical pattern image that right eye is seen, right and left eyes respectively at different viewpoints picture with the aid of pictures so that with it in conjunction with forming 3D rendering.As shown in Figure 1, parallax barrier 20 has hole 22 and occlusion part 21, have the left eye that corresponds respectively to the beholder and the left-eye image pixel L (being used to form left-eye image) and the eye image pixel R (being used to form eye image) of right eye in the two dimensional image display module 10, pixel L and R alternately are formed in the two dimensional image display module 10.Thereby every eyes are seen different images by the hole 22 of parallax barrier 20.Left-eye image pixel L output light will be imported into left eye, and eye image output light will be imported into right eye, observe the left-eye image and the eye image of being divided thus respectively, thereby obtain stereoscopic sensation.
Figure 2 shows that the simple structure synoptic diagram of the stereoscopic display device of conventional use parallax barrier.Stereoscopic display device comprises two dimensional image display module 10 and parallax barrier 20, backlightly enters from two dimensional image display module 10, through entering observer's glasses behind the occlusion part in the parallax barrier 20.In the parallax barrier 20, be to reverse realization to blocking from the light of two dimensional image display module 10 by liquid crystal.In this example, parallax barrier 20 comprises the following polaroid 210 that sets gradually from bottom to top, following transparent electrode layer 220, liquid crystal (LC) layer 230, goes up transparent electrode layer 240 and go up polaroid 250.Normally, following transparent electrode layer 220, last transparent electrode layer 240 are by ITO (Indium Tin Oxide, indium tin metal oxide) conductive glass layer, on following transparent electrode layer 220 and the last transparent electrode layer 240 at the ITO electrode that is formed with certain pattern in opposite directions in the surface of liquid crystal layer 230 respectively, by can control the reversing of liquid crystal to the control of ITO electrode to form occlusion part.
Notice touch-screen widespread use in various individual mobile display devices simultaneously.In the touch-screen,, mainly can be divided into resistive touch screen and capacitance touch screen according to principle of work.Further capacitance touch screen mainly comprises self-capacitance touch-screen (self-capacitive touch screen) and mutual capacitance touchscreens (mutual capacitive touch screen).
In the self-capacitance touch-screen, (glass substrate or polyester material are (for example at its transparent electrode substrate, PET (ethylene terephthalate, polyethylene terephthalate)) surface substrate), adopt ITO transparent conductive materials such as (Indium Tin Oxide, indium tin metal oxides) to be made into laterally and the longitudinal electrode array, these horizontal and vertical electrodes form electric capacity with earth terminal respectively, this electric capacity is usually said self-capacitance, just electrode electric capacity over the ground.When finger touch when the capacitance plate, the electric capacity of finger will be added on the self-capacitance, and the touch-screen electric capacity is increased.The control circuit of self-capacitance touch-screen comes the senses touch position by the variation of measuring capacitive load.
In the mutual capacitance screen,, adopt ITO transparent conductive materials such as (Indium TinOxide, indium tin metal oxides) to be made into laterally and the longitudinal electrode array on the surface of its transparent electrode substrate; The difference that it and self-capacitance shield is that the place that longitudinal electrode and transverse electrode intersect will form mutual capacitance, also is the two poles of the earth that this longitudinal electrode and corresponding transverse electrode have constituted electric capacity respectively.When finger touch arrives capacitance plate, influenced the coupling between near two electrodes in touch point, thereby changed the electric capacity between these two electrodes.When detecting the mutual capacitance size, in one example, horizontal electrode sends pumping signal successively, longitudinally all electrodes while received signals, can obtain the capacitance size of all horizontal and vertical electrode joints like this, promptly obtain the capacitance size of the two dimensional surface of whole touch screen.According to the variation of the electric capacity data of two dimensional surface in the touch-screen scope, can calculate the coordinate of each touch point.
Yet, when parallax barrier 20 is applied to have the individual mobile display device of capacitive touch screen, for example, touch-screen mobile phone etc., if directly on touch-screen, cover parallax barrier 20 to reach the stereo-picture display effect, so because the existence of parallax barrier 20 will cause the disabler of the touch input information of touch-screen.
In view of this, at the requirement that requires to have touch-input function and stereo-picture Presentation Function simultaneously,, be necessary to capacitance touch screen and parallax barrier integrating especially to capacitance touch screen.
