Abstract: An electroluminescence display apparatus includes a display panel, including a pixel including a driving element and a light emitting device, and a panel driving circuit supplying the pixel with a first data voltage for a display driving operation and a display scan signal synchronized with the first data voltage in a vertical active period succeeding a first vertical blank period and maintaining the first data voltage in the pixel during a second vertical blank period succeeding the vertical active period, wherein a length of the first vertical blank period is fixed regardless of a variation of a frame frequency, and a length of the second vertical blank period varies based on the variation of the frame frequency.

Abstract: Disclosed herein is a data interface device of a display apparatus including a timing controller, encoding clock-embedded image data corresponding to a logic high period of a data enable signal and clock-embedded blank data corresponding to a logic low period of the data enable signal and transferring an encoded data transfer packet to a transfer line, and a source integrated circuit generating an internal clock based on the encoded data transfer packet received through the transfer line and selectively decoding the clock-embedded image data based on the internal clock, wherein a transition pattern of the clock-embedded blank data differs in a plurality of transfer lines.

Abstract: An OLED display device capable of improving picture quality by turning off an OLED element regardless of a charging time and input data of each subpixel is discussed. A reference voltage supplied to a reference line is supplied to an OLED element during at least one OLED off time after a light-emitting time and before a charging time according to control of a scan gate line and a sense gate line to turn off the OLED element. The reference voltage is lower than a threshold voltage of the OLED element.
