Abstract: An organic light-emitting diode (OLED) display can include a display panel including sub-pixels; a deterioration sensing unit configured to sense a deterioration state of the display panel; a power supply configured to output a high voltage for driving the sub-pixels; and a timing controller configured to: receive a deterioration sensing result including information on the deterioration state of the display panel from the deterioration sensing unit, continuously vary the high voltage based on the deterioration sensing result received from the deterioration sensing unit, and provide the varied high voltage to the sub-pixels.

Abstract: The present disclosure relates to a display interface device which can increase display information transmission efficiency and reduce power consumption and EMI, in which a transmission part transmits clock edge information included in a data packet of each channel at a different timing from clock edge information included in data packets of other channels. A reception part detects a clock edge of each channel from the data packet transmitted through each channel, generates an internal clock signal of each channel, synchronized with the detected clock edge, corrects a delay of each channel depending on a result of a logical operation performed on a delayed clock edge of a channel and a clock edge of another channel to further generate an internal clock signal of each channel, and restores the display information from the data packet of each channel using the internal clock signal of each channel.

Abstract: A display device performs efficient driving by selectively scanning a peripheral area processed to have low resolution. The display device includes a gate driver that scans a first subset of pixel rows in a first scan block including only the peripheral area during a first frame and a second frame, and respectively scan during the first frame and the second frame a second subset of pixel rows and a third subset of pixel rows in a second scan block including the medial area and the peripheral area excluding the foveal area, and scan pixel rows of pixels in a third scan block including the foveal area, the medial area, and the peripheral area during the first frame and the second frame.
