Abstract: A display apparatus includes a data driver and a light valve controller. The data driver is configured to continuously provide K display signals, all of which include a same set of image data, to a display panel. K is an integer greater than or equal to 2. The light valve controller is configured to provide a turn-off signal to a light valve whenever the data driver provides one of first T or odd-numbered display signals in the K display signals, and provide a turn-on signal to the light valve whenever the data driver provides one of last (K−T) or even-numbered display signals in the K display signals. T is an integer greater than 0 and less than K, and (K−T) refers to a difference between K and T.

Abstract: A method for processing an image in a virtual reality display device and a related virtual reality display device are provided. A gaze area and a non-gaze area are determined in a display area of a virtual reality display device. At a first time instant, a rendering process is performed in the gaze area and the non-gaze area to generate a first image. Based on attitude information of the virtual reality display device at a second time instant, a time warping process is performed on the first image to generate a second image. Based on the movement information and attribute information of the motion object in the gaze area, the second image is modified. With the modifying the second image, problems caused by the time warping process can be avoided, delays can be reduce, and smearing or ghosting can be avoided, thus a good display effect can be obtained.

Abstract: Disclosed is a display driving method, an upper machine, a lower machine and a display driving system. The method includes: acquiring, by a lower machine, an address for any of subpixels transmitted from an upper machine; looking up, by the lower machine, a gray scale data corresponding to the pointer address in a display Look-UP Table (LUT), wherein the LUT stores mapping relationships between respective pointer addresses and their corresponding gray scale data; performing, by the lower machine, a digital-analog conversion on the gray scale data to acquire a converted analog voltage; and outputting the analog voltage to the subpixel so as to drive the subpixel for displaying. The method can increase the transmission rate between the GPU and the display to a certain degree and reduce the power consumption thereof.
