Abstract: An organic light emitting display device comprising: a source device configured to output image data; and a sink device configured to perform a displaying operation based on the image data, wherein the source device is configured to change a frame rate of an image frame composing the image data while the displaying operation is performed, wherein the sink device is configured to change a frame rate of a panel driving frame for the displaying operation as the frame rate of the image frame is changed, and wherein the source device is configured to change the frame rate of the image frame while satisfying a condition in which an emission duty ratio of the panel driving frame is not changed.

Abstract: A display device includes a source device to output image data in a normal mode and in a re-synchronization mode, and refrain from outputting the image data in a panel self-refresh mode, and a sink device to perform a displaying operation based on the image data in the normal mode, store the image data at a time when an operating mode is changed from the normal mode to the PSR mode, perform the displaying operation based on the still image data in the PSR mode, and perform a frame-timing synchronization operation in the re-synchronization mode in response to a PSR-exiting command, wherein the frame-timing synchronization operation includes a first period in which a length-change of a vertical blank period is measured, a second period in which a temporary panel on-off clock is determined, and a third period in which the temporary panel on-off clock is applied to the adjustment-target frame.

Abstract: A liquid crystal display system including a signal processing device uses interpolation to generate an intermediate image frame using previous image frame data and present image frame data. The system converts data of the intermediate image frame into transposed image data that is to be used to drive a liquid crystal display panel and display a corresponding image. The transposed image data and the present image data are subjected to a prespecified DCC process (dynamic capacitance compensation process) to thereby generate respective first and second compensation image data. Since the first compensation image data is generated based on the transposed image data and the transposition is configured to prevent over-compensation by the DCC process, over-compensation by the dynamic capacitance compensation process can be reduced or prevented.
