Abstract: An organic light emitting diode (OLED) display and an operating method thereof are provided. The organic light emitting diode display includes an organic light emitting diode display panel and a driving circuit. The organic light emitting diode display panel has a plurality of pixels. The driving circuit is coupled to the organic light emitting display panel and receives a primitive display frame. The driving circuit generates a first frame and a second frame corresponding to the primitive display frame by a polarity inverting means, and outputs a zero gray-level pixel voltage to the corresponding pixels of the organic light emitting diode display panel corresponding to a negative polarity data of the first frame and the second frame, wherein the second frame is adjacent to the first frame.

Abstract: A multi-dimensional touch display device includes a multi-dimensional display device and a touch sensing device. The multi-dimensional display device is used to provide stereoscopic images with different depths. The touch sensing device connected to the multi-dimensional display device has a plurality of sensing surfaces for determining a planar coordinate and a depth of a touch input point.

Abstract: An image processing device and a method thereof are provided. The image processing device includes a controller and an image processing unit. The controller generates a timing control signal according to an enabling signal. The image processing unit is coupled to the controller. The image processing unit receives a gray scale value of a pixel at a time and determines whether to change the gray scale value of the pixel at the time to a predetermined gray scale value according to the timing control signal. Thereby, the image quality is improved.
