    摘要: A display device is provided and includes a display panel, a light source, a light source controller, and a timing controller. The light source is adjacent to the display panel. The light source controller is electrically connected to the light source. The timing controller is electrically connected to the light source controller and the display panel. The timing controller includes a decoding unit and first and second processing units. The first processing unit is electrically connected to the decoding unit and the display panel. The second processing unit is electrically connected to the decoding unit and the light source controller. The decoding unit provides a refresh signal to the first and second processing units so that the display panel refreshes displayed content in a first refresh sequence according to first refresh rates, and the light source refreshes brightness in a second refresh sequence according to second refresh rates.

    摘要: A light source driving circuit and a method for driving a light source are provided. The light source driving circuit includes a filter. The filter is configured to receive a pixel signal. The filter selects one filter parameter from multiple filter parameters according to a gray level value of the pixel signal. The filter performs a filter operation on the pixel signal according to the selected filter parameter, so as to output a driving signal to drive a light source module. The filter parameters include a first filter parameter, a second filter parameter, and a third filter parameter. The second filter parameter is obtained by performing an interpolation operation on the first filter parameter and the second filter parameter via the filter.
