Abstract: A signal transmitter of the invention is coupled to a plurality of signal receivers by a bus, and is configured to transmit display data through the bus for displaying a line. The signal transmitter includes a first data sequence and a second data sequence. The first data sequence has an electronic characteristic of a first value and is transmitted to a first signal receiver of the signal receivers, and the second data sequence has the electronic characteristic of a second value to a second signal receiver of the signal receivers. Wherein, a first signal transmission path from the signal transmitter to the first signal receiver is shorter than a second signal transmission path from the signal transmitter to the second signal receiver, and the first value is larger than the second value.

Abstract: A display device including a timing controller, a data driving circuit and a display system is provided. The timing controller outputs first pixel data according to input pixel data, wherein a color depth of the first pixel data is a first bit number or a second bit number smaller than the first bit number. The data driving circuit receives the first pixel data and a notice signal, and maps the first pixel data to generate second pixel data according to the notice signal when the color depth of the first pixel data is the second bit number, and directly takes the first pixel data as the second pixel data when the color depth of the first pixel data is the first bit number, and generates at least one driving voltage according to the second pixel data, wherein the color depth of the second pixel data is the first bit number.

Abstract: A display device includes an image receiving unit, a power-saving control device, a display control unit, and a backlight module control unit. The power-saving control device judges whether or not received frames are still for a predetermined time. If the power-saving control device judges that the received frames are still for the predetermined time, the power-saving control device outputs a first control signal to the display control unit for controlling the display panel to perform power saving to reduce its power consumption while continuing displaying frames, and the backlight module control unit controls the backlight module to continue providing the backlight; while if the received frames are not still or are still for a time shorter than the predetermined time, the power-saving control device does not output the first control signal to the display control unit for controlling the display panel to perform power saving to reduce its power consumption.

Abstract: A timing control circuit configured to drive a source driver circuit is provided. The timing control circuit includes a signal receiving unit and a signal output unit. The signal receiving unit receives an input signal. The input signal includes an image signal. The signal output unit generates an output signal according to the input signal. The output signal includes the image signal. A period when the input signal corresponds to a static image includes one or more frame partially-masked periods. During a first time interval of the frame partially-masked period, the image signal of the output signal is not masked but output by the signal output unit. During a second time interval of the frame partially-masked period, the image signal of the output signal is masked but not output by the signal output unit. Furthermore, a display driving method of a display panel is also provided.
