Abstract: A system includes a display panel having an input to receive pixel data representative of a sequence of display images and an array of display elements. Each display element includes a first buffer stage, a second buffer stage coupled to the first buffer stage, and a light emitting diode (LED) coupled to the second buffer stage. The display panel further includes a controller to control the array of display elements to concurrently activate the LEDs of the array for a first time interval based on pixel data of a first display image stored at the second buffer stages of the array of display elements and to receive and store at least a portion of pixel data of a second display image at the first buffer stages of the array of display elements during the first time interval.

Abstract: A head mounted display (HMD) device includes a left-eye display panel and a right-eye display panel. Each of the left-eye and right-eye display panels includes a proximate edge, a distal edge, an active display area having a proximate border and a distal border. A distance between the proximate border and the proximate edge is less than a distance between the distal border and the distal edge. For each display panel, a first border region defined by the distal edge and the distal border contains circuitry for operating pixels of the active display area, whereas a second border region defined by the proximate edge and the proximate border is devoid of circuitry.

Abstract: A pixel driving technique for an organic light emitting diode (OLED) display. A frame of image data is shifted into an OLED panel and activated for global illumination. During the time period of global illumination for the frame of image data, pixel data for a next frame of image data is buffered in a partial memory. After the period of global illumination for the frame of image data, the next frame of image data being buffered in the partial memory is read out of partial memory to the OLED panel and updates the previous frame of pixel data with the new pixel data.
