Be described in detail below in conjunction with the implementation procedure of Figure of description to the embodiment of the present invention.It should be noted that same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not limitation of the present invention being interpreted as.
See Fig. 1, the embodiment of the present invention provides a kind of 3D touch-control to show module, and comprise liquid crystal grating 1 and liquid crystal panel 2, liquid crystal grating 1 comprises upper substrate 11 and infrabasal plate 12, and liquid crystal panel 2 comprises array base palte 21 and subtend substrate 22;
Liquid crystal grating 1 also comprise be formed at upper substrate 11 towards infrabasal plate 12 one side some grating electrodes 13, each grating electrode 13 be positioned at every setpoint distance arrange strip region; And also comprise some touch-control sensing electrodes that be made up of inductor electrode 14, that arrange with layer with grating electrode 13, in the interval region of each inductor electrode 14 between adjacent strip region;
Liquid crystal panel 2 also comprises and is formed at the some touch-control drive electrodes 23 of subtend substrate 22 towards subtend substrate 22 one side, and each touch-control drive electrode 23 is parallel to each other and different from each inductor electrode 14 wiring direction.
Certainly, arrange liquid crystal 15 between the upper substrate 11 of liquid crystal grating 1 and infrabasal plate 12, when grating electrode 13 powers up, the liquid crystal 15 of grating electrode 13 correspondence rotates, thus realizes grating display.Such as, liquid crystal is horizontal alignment when grating electrode 13 does not power up, and after grating electrode 13 powers up, the postrotational angle of liquid crystal 15 and horizontal alignment have angle.
In the present embodiment, by the upper substrate 11 at liquid crystal grating 1, grating electrode 13 and touch-control sensing electrode are set towards the one side of infrabasal plate 12, thus form strip grating; Meanwhile, arrange touch-control drive electrode 23 at the subtend substrate 22 of liquid crystal panel 2 towards the one side of subtend substrate 22, the touch-control sensing electrode that the touch-control drive electrode 23 inductor electrode 14 different from wiring direction is formed realizes touch controllable function.Because grating electrode 13, touch-control sensing electrode and touch-control drive electrode 23 are arranged in liquid crystal grating 1 and liquid crystal panel 2 respectively, and grating electrode 13 and touch-control sensing electrode are arranged with layer, while realizing 3D touch display function, the thickness that whole 3D shows module can be reduced; Grating electrode 13 and the same layer of touch-control sensing electrode, do not need to form rete respectively, can reduce costs.
See Fig. 2, in order to make the signal to noise ratio (S/N ratio) between the inductor electrode 14 of touch-control sensing electrode and touch-control drive electrode 23, touch-control sensitivity is improved, liquid crystal grating 1 can also comprise be positioned at upper substrate 11 towards infrabasal plate 12 one side floating electrode 16, each floating electrode 16 is positioned at the interval region except being provided with inductor electrode 14.Certainly, floating electrode 16 need not apply voltage.
Adapt to the signal to noise ratio (S/N ratio) requirement of the requirement of touch accuracy, the quantity of the floating electrode 16 arranged between adjustment two inductor electrodes 14 that can be suitable.Because in 3D display, the width between the fence of liquid crystal grating 1 when carrying out grating display is usually less, such as micron-sized width.And the inductor electrode 14 needed for touch-control needs to set according to precision, be far smaller than the density of pixel arrangement, therefore inductor electrode 14 can have larger space, can arrange floating electrode 16.Preferably, a floating electrode 16 is at least provided with between adjacent two inductor electrodes 14.
