摘要： A LED driving circuit comprises a high bit driving circuit, a low bit driving circuit and a driving output terminal. The high bit driving circuit coupled to a high bit signal of the grayscale signal determines a first current continuously driven during a grayscale period according to the value of the high bit signal. The first current is invariant during the grayscale period. The low bit driving circuit coupled to a low bit signal of the grayscale signal determines a second current driven in at least two time intervals during the grayscale period according to the value of the low bit signal. The driving output terminal coupled to the high bit driving circuit and the low bit driving circuit outputs the driving current added by the first current and the second current. Accordingly, the LED display can be improved with higher refresh rate and/or better uniformity in low grayscale.

摘要： A display device includes a processor including a first display mode in which the processor displays the image on the display screen from an internal image data after the processor receives a first control signal, and a second display mode in which the processor displays the image on the display screen from the image data received by the processor after the processor receives a second control signal. A luminance adjuster adjusts a display luminance based on the internal image data corresponding to a final frame immediately before switching from the first display mode to the second display mode to a display luminance lower than a display luminance of the internal image data of another frame in the first display mode. In the final frame, the image is displayed based on the internal image data in which the display luminance is adjusted by the luminance adjuster.
