Abstract: A portable electronic device comprises a double-sided display including a first display side and a second display side formed on a side opposite the first display side; a direct memory access (DMA) controller configured to read first image data from a memory; at least one sensor configured to detect at least one of a position change of the double-sided display and a movement of a user's pupil and to output a detection signal; a status signal generator configured to interpret the detection signal output and to output a status signal; a transmission order determiner configured to receive the first image data from the DMA controller, to determine a transmission order of the first image data based on the status signal, and to output second image data corresponding to the determined transmission order; and a display driver integrated circuit (IC) configured to transmit the second image data to the display.

Abstract: A display system is provided. The display system includes a perframe controller configured to receive a frame synchronization signal and to change values of M and N in synchronization with at least one pulse of the frame synchronization signal, where M and N are natural numbers; and a fractional divider configured to generate and output a pixel clock signal by dividing an input clock signal by a division ratio of N/M.

Abstract: In one example embodiment, a method of operating an image data processing circuit which controls an operation of an organic light-emitting diode (OLED) display includes transforming at least one first RGB value into at least one luminance value and at least one chroma value. The method further includes adjusting the at least one luminance value and the at least one chroma value based on at least one first control value. The method further includes generating at least one second RGB value based on the at least one adjusted luminance value and the at least one adjusted chroma value. The method further includes outputting the second RGB values to the OLED display.

Abstract: A system on chip (SoC) includes a display controller configured to receive data of a current frame and to determine whether the data of the current frame has been updated from data of a previous frame, and a transmitter configured to output a panel self-refresh (PSR) inactive command and the data of the current frame when the display controller determines that the data of the current frame has been updated and to transmit a panel self-refresh (PSR) active command when the display controller determines that the data of the current frame has not been updated.
