Abstract: A slit grating and a three-dimensional (3D) display apparatus including the slit grating are disclosed herein, the slit grating includes a plurality of grating structures (11-17) arranged side by side. The widths of the grating structures (11-17) increase and then decrease, along the direction in which the grating structures (11-17) are arranged. A grating structure (13,14) having the largest width may define a trend change point after which the trend in the widths of the grating structure widths changes.

Abstract: The present disclosure relates to a touch panel controller, a control information acquisition method and a touch display device in the field of display technology. The touch panel controller includes at least two conductive members and a rotating component. The rotating component includes a supporting component and a mounting component connected to each other. The mounting component is configured to have the at least two conductive members mounted thereon. One end of the supporting component is configured to determine a placement surface that is in contact with a touch panel. A distance between each of the at least two conductive members and the placement surface is less than a sensing distance, and the sensing distance is a distance at which a capacitance change caused by the conductive member is detectable by the touch panel. In the present disclosure, a plurality of rotatable conductive members in the controller are used to input a multi-point touch operation such as rotation or multi-point sliding, which solves the problem in the related art that it is difficult for the stylus to accomplish multi-point touch operations and achieves an effect of performing a variety of multi-point touch operations through the controller.

Abstract: Provided are a display driving circuit, a driving method thereof and a display apparatus. The display driving circuit comprises a timing sequence control unit (20) and at least one signal driving unit (30) connected to the timing sequence control unit (20). The timing sequence control unit (20) comprises a receiving module (201), a processing module (202) and a sending module (203). The receiving module (201) receives feedback signals (FB) outputted from respective signal driving units (30) to the timing sequence control unit (20); the processing module (202) obtains a maximum delay time after comparing signal delay time of the signal driving units (30) according to the feedback signals (FB); the sending module (203) sends a second clock signal (CLK2) to respective signal driving units (30) according to the maximum delay time such that respective signal driving units (30) receive the second clock signal (CLK2) simultaneously. Therefore, delay errors of the display driving signals can be eliminated, and distortion of the display image can be avoided.
