    Abstract: 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.

    Abstract: A display data adjustment method is provided, including the following. First display data is received, and first grayscale values of first sub-pixels of different colors in the first display data are converted from a first color gamut space into color values in a second color gamut space. First weight values are generated according to the color values. Lookup tables are compared according to the first grayscale values of the first sub-pixels to obtain groups of first high grayscale values and first low grayscale values corresponding to the first sub-pixels. Second high grayscale values and second low grayscale values are obtained by calculation according to the groups of the first high grayscale values and the first low grayscale values and the first weight values. The second high grayscale values or the second low grayscale values are selected as second grayscale values of second sub-pixels in second display data.

    Abstract: An electronic device includes gate lines, maintained at a low level voltage during a blank period and sequentially scanned during an active period in a frame period, and data lines. Voltage polarities of the data lines for all the blank period are respectively identical with voltage polarities of the data lines during the active period. A first level voltage applied to one of the data lines during all the blank period is related to an average value or a maximum value of level voltages of a portion or all of the data lines during the active period. A time length of the blank period in the frame period with the average value or the maximum value applied to one of the data lines during all the blank period is longer than a first time length of a first blank period in a first frame period adjacent to the frame period.

    Abstract: The present disclosure provides an electronic device and a driving method thereof. The electronic device includes a pixel compensation circuit and a display panel. The pixel compensation circuit receives a pixel signal. The pixel signal includes multiple sub-pixel gray-scale values. The pixel compensation circuit compensates the sub-pixel gray-scale value according to the difference between the sub-pixel gray-scale values and the first threshold value to output an adjusted pixel signal. The display panel displays an image screen according to the adjusted pixel signal.
