When image signal IS is 2D image signal, no matter whether contact panel 112 produces touch signal TS, time schedule controller 102 switches signal TTSS according to image signal IS and 2D/3D, produces the first sequencing control signal FTCS and the second sequencing control signal STCS.Then, liquid crystal grating controller 104, according to the first sequencing control signal FTCS, produces liquid crystal grating and control signal LBCS, and backlight controller 106 is according to the second sequencing control signal STCS, produces and export backlight illumination to control signal BLCS.In addition, in order to balancing touch panel 112 shows the brightness that the brightness of 2D image signal and contact panel 112 show 3D image signal, when contact panel 112 shows 2D image signal, backlight driving unit 108 controls the work period (dutycycle) meeting lower (such as 50%) of the backlight drive signal BDS that signal BLCS produces according to backlight illumination.Please refer to Fig. 2 and Fig. 3, Fig. 2 is the schematic diagram that contact panel 112 is described, and Fig. 3 is the image signal IS (2D image signal), the common voltage VCOM (0V DC signal) of contact panel 112 and the schematic diagram of liquid crystal grating control signal LBCS (0V DC signal) that illustrate that contact panel 112 receives.As shown in Figure 2, contact panel 112 has left eye grating and right eye grating.Therefore, as shown in Figure 3, when contact panel 112 receives image signal IS (2D image signal) and liquid crystal grating controls signal LBCS (0V DC signal), because the common voltage VCOM of contact panel 112 and the liquid crystal grating pressure reduction controlled between signal LBCS is zero, so the left eye grating of contact panel 112 and the liquid crystal of right eye grating can not reflect image signal IS (2D image signal).Therefore, simultaneously the right and left eyes of a user receives image signal IS (2D image signal).
As shown in Figure 4, when image signal IS is 3D image signal and contact panel 112 does not produce touch signal TS, time schedule controller 102 switches signal TTSS according to image signal IS and 2D/3D, produce the first sequencing control signal FTCS and the second sequencing control signal STCS, and picture unit map 1022 is left-eye images signal according to image signal IS and right-eye image signal, produce and output processed image signal PIS to contact panel 112.Then, the square wave generation unit 1042 that liquid crystal grating controller 104 comprises can according to the first sequencing control signal FTCS, produce liquid crystal grating and control signal LBCS, and backlight controller 106 is according to the second sequencing control signal STCS, produce and export backlight illumination and control signal BLCS, wherein liquid crystal grating controls signal LBCS is an AC signal (AC signal such as between 0V and 5V), and the common voltage VCOM of contact panel 112 is also an AC signal (AC signal such as between 0V and 5V).In addition, as the image signal PIS that contact panel 112 Graphics Processing is crossed, backlight driving unit 108 controls work period of the backlight drive signal BDS that signal BLCS produces according to backlight illumination can higher (such as 100%).As shown in Figure 4, when contact panel 112 receives the image signal PIS and liquid crystal grating control signal LBCS (AC signal) that processed, because the common voltage VCOM of contact panel 112 and liquid crystal grating control the pressure reduction non-vanishing (such as 5V) between signal LBCS, the left eye grating of contact panel 112 and the liquid crystal of right eye grating can reflect the image signal PIS processed.Therefore, at period T1, period T3 and period T5, the left-eye images of the image signal PIS processed can be allowed to pass through for the left eye grating of contact panel 112 and the right eye grating of contact panel 112 can stop the right-eye image of the image signal PIS processed, so the left eye of user can receive the left-eye images of the image signal PIS processed; At period T2, period T4 and T6, the right-eye image of the image signal PIS processed can be allowed to pass through for the right eye grating of contact panel 112 and the left eye grating of contact panel 112 can stop the left-eye images of the image signal PIS processed, so the right eye of user can receive the right-eye image of the image signal PIS processed.

In sum, the control system being applied to touch-control and changeable 2D/3D pattern provided by the present invention has following advantages: the first, the present invention can reduce cost and the power consumption of control system; The second, because control system is integrated control system, thus the present invention can simplified control system and main frame, control mode between contact panel; Three, because the control of the function of the touch controllable function of control system assembling contact control panel and display 2D/3D image, so the present invention can provide preferably contact panel characteristic; Four, the present invention according to display 2D/3D image and touch signal, can adjust corresponding touch parameter and switchable liquid crystal grating control signal (DC signal or AC signal); Five, the present invention can show 3D image in the straight position of contact panel (the long limit of contact panel is perpendicular to horizontal plane) and horizontal type position (the long limit of contact panel is parallel to horizontal plane); Six, the present invention the brightness of balancing touch Display panel 2D image signal and contact panel can show the brightness of 3D image signal.
The foregoing is only preferred embodiment of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
