Abstract:
A display device may reduce the latency of the display of a digital signal by reducing the latency that the display device adds to the digital signal. After a digital signal is received by an input module, the signal is stored in a frame buffer as a plurality of pixels. A controller determines the input frame rate of the digital signal and a pixel delay. The controller monitors the frame buffer to determine when the frame buffer has stored a number of pixels greater than or equal to the pixel delay. After the frame buffer contains enough pixels, the controller initiates transmission of the pixels from the frame buffer to a display module. In certain embodiments, the controller initiates transmission of the pixels to the display module before the frame buffer has stored all pixels corresponding to the frame.
