Abstract: An organic light emitting diode display device includes a display module having a display panel and a panel driver; a host system separated from the display module with a timing controller to control the panel driver; and an interface device between the host system and the display module. The interface device includes a cable between the host system and the display module, a transmission module to compress display data from the timing controller in an active period of each frame without compressing sensing data and recovery data supplied in a blank period of the frame and to transmit the compressed display data, the non-compressed sensing data and recovery data via the cable, and a reception module to decompress the compressed data transmitted via the cable, to supply the decompressed data to the panel driver, and to supply the non-compressed data to the panel driver without data processing.

Abstract: An organic light emitting diode (OLED) display device is discussed. The OLED display device includes a display module including a display panel and a panel driver for driving the display panel, and a host system externally separated from the display module. The OLED display device further includes an interface device including a transmission module configured to transmit sensing data via a plurality of vertical synchronization signals for communication between the host system and the display module. The transmission module generates first and second vertical synchronization signals having blank periods that are not overlapping with each other. The interface device transmits the sensing data in a sensing period of one vertical synchronization signal that overlaps with the blank period of another vertical synchronization signal.
