Abstract: The present application discloses a display device and electronic device. The display device is configured by sequentially configuring the corresponding first bias current, second bias current, and third bias in a start period, a sustain period, and an end period. The current value of the first bias current is greater than the current value of the second bias current, and/or the current value of the third bias current is greater than the current value of the second bias current, which improves the display quality and reduces display power consumption.

Abstract: A timing controller, a clock reset method, and a display panel are provided. When an abnormal working condition occurs in a transition stage of recovering a reset control signal from a jumping state to an initial state, the problem that a clock of the timing controller cannot be synchronized can be avoided when a processing module cannot normally output a clock reset pulse signal and a clock data recovering module cannot normally recover the clock of the timing controller because the reset control signal is in the jumping state. Reliability of the timing controller is increased.

Abstract: A liquid crystal display backlight module controlling method and a controlling device thereof disclosed in the present invention includes a programmable logic gate array board extracting backlight information from an image signal. Calculation of local dimming is performed by the programmable logic gate array board, a calculation buffer for local dimming calculation is sufficient, which can increase liquid crystal display backlight divisions. Furthermore, the present invention employs a row signal and a column signal to control and switch on light emitting diodes in the backlight light board, which can achieve the cost lowering effect.

Abstract: The present application discloses a display panel and an electronic device. The display panel includes a power access end configured to supply a first power voltage. A driving module is configured to input a second power voltage to a second end of a light-emitting element under a control of a data signal. An equivalent resistance of a driving module of a pixel adjacent to the power access end is greater than an equivalent resistance of a driving module of a pixel away from the power access end.

Abstract: The present invention provides a backlight unit and a control method thereof, and a liquid crystal display device. The control method includes steps as follows: obtaining backlight data corresponding to each partition, wherein the backlight data comprises a plurality of bits of data; dividing the light-emitting unit of each partition into a plurality of subfields with different durations in a light-emitting process during a frame, wherein each subfield corresponds to one bit of data, and any two subfields comprise different numbers of secondary subfields; and outputting the plurality of subfields in a preset order.
