Abstract: A method includes: obtaining a first frame synchronization signal, period between a trailing edge of a first pulse and a leading edge of a next first pulse being first time period corresponding to a first integer number of pulses of a first pixel clock signal; generating a synchronization calibration signal, a triggering edge of the second pulse being delayed compared to a trailing edge of a first pulse; generating a second frame synchronization signal, period between a triggering edge of the second pulse and a leading edge of a third pulse being second time period. When ratio of frequency of the second pixel clock signal to frequency of the first pixel clock signal is within threshold range, the second time period corresponds to a second integer number of pulses of the second pixel clock signal. The second integer is integer value of product of the first integer and ratio.

Abstract: There is provided a data processor for a display device including a display panel having a first resolution. The data processor includes a first mode selector and a player. The first mode selector includes a distance detector, a comparator, and a transmission resolution adjustor. The distance detector may detect a current distance between a viewer and a display surface of the display panel. The comparator determines an amount of change of the current distance from a previous distance. The transmission resolution adjustor determines a second resolution according to a threshold range within which the previous distance falls and the amount of change. The player processes received external image data as intermediate data having the second resolution.
