At present, along with the development of Touch Screen technology, the 3D display device that touch-screen and 3-D display are combined has appearred; Its structure is on three-dimensional display screen, to increase one deck touch base plate, and the manufacturing process more complicated of this structure requires than higher for the aligning accuracy of touch base plate applying three-dimensional display screen; Therefore, the integral manufacturing cost is higher relatively, and; Because touch base plate and three-dimensional display screen are provided with separately, therefore, it is also thicker to obtain thickness of product; In addition, touch base plate also can influence the display effect of three dimensional grating.
The liquid crystal grating that adopts the utility model embodiment to provide; Do not increasing the liquid crystal grating integral thickness and do not influencing under the situation of 3-D display; Not only can realize twocouese three dimensional grating display mode, can also realize the function of capacitance type touch control screen, detail through instantiation below.
In following instance, the first direction strip shaped electric poles in the liquid crystal grating that the utility model embodiment provides is set to the longitudinal strip electrode, and the second direction strip shaped electric poles is set to horizontal strip shaped electric poles.
Usually; The pixel of touch screen is usually in the millimeter level, and the pixel of 3-D display can be found out usually at micron order; It is many that the required drive electrode drive electrode more required than the barrier fence of touch screen lacks; Can expect that with the horizontal strip shaped electric poles of barrier fence or longitudinal strip electrode simultaneously as the drive electrode that drives liquid crystal deflection and the drive electrode of touch screen, the part in longitudinal strip electrode or the horizontal strip shaped electric poles can realize touch controllable function as the induction electrode of touch screen.
Therefore, we define every longitudinal strip electrode at a distance from the M bar is the touch-control electrode, and the longitudinal strip electrode except that the touch-control electrode is a grating electrode; The every horizontal strip shaped electric poles at a distance from the N bar of definition is the touch-control electrode, and the horizontal strip shaped electric poles except that the touch-control electrode is a grating electrode.Wherein, the numerical value of M and N can be set according to the resolution of touch-control, in addition, can M and N be arranged to identical numerical value or different numerical value according to the Aspect Ratio of the display screen of liquid crystal grating.
In following instance; The longitudinal strip electrode is set to the n bar with the number of horizontal strip shaped electric poles; The numerical value of M and N is set to 2, and two longitudinal strip electrodes in promptly every interval or horizontal strip shaped electric poles are touch-control electrode, i.e. n bar, n-3 bar, n-6 bar ... Be the touch-control electrode.
We are divided into two types with the first electric signal input/output terminal; The first kind first electric signal input/output terminal PIN V and a plurality of second type of first electric signal input/output terminal PIN A; Wherein, PIN V links to each other with the longitudinal strip electrode that is defined as grating electrode in advance through lead, and a PIN A links to each other with a longitudinal strip electrode that is defined as the touch-control electrode in advance, and the number of the touch-control electrode in the number of PIN A and the longitudinal strip electrode is identical.
The second electric signal input/output terminal also is divided into two types; The first kind second electric signal input/output terminal PINH and a plurality of second type of second electric signal input/output terminal PIN B; Wherein, PIN H links to each other with the horizontal strip shaped electric poles that is defined as grating electrode in advance through lead, and a PIN B links to each other with a horizontal strip shaped electric poles that is defined as the touch-control electrode in advance, and the number of the touch-control electrode in the number of PIN B and the horizontal strip shaped electric poles is identical.
Use the unified first kind first electric signal input/output terminal PIN V or the first kind second electric signal input/output terminal PIN H to grating electrode input ac voltage signal; Both can make things convenient for the synchronous input of voltage signal, also can reduce the first total electric signal input/output terminal and the quantity of the second electric signal input/output terminal.
Instance one: the vertically realization of 3-D display and touch controllable function, as shown in Figure 4.

Like this, horizontal strip shaped electric poles and face electrode after the energising have formed electric field, make corresponding liquid crystal deflection form the barrier fence, have realized vertical three dimensional grating display mode.
Touch-control electrode in the horizontal strip shaped electric poles after the energising is as the drive electrode of touch-control, and the touch-control electrode in the longitudinal strip electrode has been realized touch controllable function as induction electrode.
Preferably, in order to increase coupling capacitance between the touch-control electrode, when increasing specific inductive capacity; And raising signal to noise ratio (S/N ratio); Thereby improve the sensitivity of touch-control, can also use the floating empty Dummy of grating electrode conduct in the longitudinal strip electrode, promptly use PIN V to connected grating electrode input 0V voltage.
Instance two: the laterally realization of 3-D display and touch controllable function, as shown in Figure 5.
Use the drive electrode of longitudinal strip electrode, promptly use PIN V to transmit ac voltage signal, specifically can be input 5V alternating current to connected grating electrode as the barrier fence; Touch-control electrode in the use longitudinal strip electrode promptly uses PIN A to the connected touch-control electrodes transfer ac voltage signal identical with PIN V as the drive electrode of touch-control, specifically can be input 5V alternating current; Use touch-control electrode in the horizontal strip shaped electric poles as induction electrode, promptly use PIN B to respond to the electric signal of connected touch-control electrode.
Like this, longitudinal strip electrode and face electrode after the energising have formed electric field, make corresponding liquid crystal deflection form the barrier fence, have realized horizontal three dimensional grating display mode.
Touch-control electrode in the longitudinal strip electrode after the energising is as the drive electrode of touch-control, and laterally the touch-control electrode in the strip shaped electric poles has been realized touch controllable function as induction electrode.
Preferably, in order to increase coupling capacitance between the touch-control electrode, when increasing specific inductive capacity; And raising signal to noise ratio (S/N ratio); Thereby improve the sensitivity of touch-control, can also use the floating empty Dummy of grating electrode conduct in the horizontal strip shaped electric poles, promptly use PIN H to connected grating electrode input 0V voltage.
