Display driving circuit and brightness control method applied to organic light-emitting diode panel

Abstract

A display driving circuit, coupled to an OLED panel, includes a brightness controller, a light-emitting scan line adjusting circuit and a light-emitting scan line generator. The brightness controller provides a brightness controlling signal. The light-emitting scan line adjusting circuit includes a first counting unit, a second counting unit and an arrangement unit. The first counting unit provides a frame counting value. The second counting unit provides a light-emitting period counting value. The arrangement unit is coupled to the brightness controller, the first counting unit and the second counting unit and used to generate an adjusting signal according to the brightness controlling signal, the frame counting value and the light-emitting period counting value. The light-emitting scan line generator is coupled to the light-emitting scan line adjusting circuit and the OLED panel and used to generate light-emitting scan lines to the OLED panel according to the adjusting signal.
