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 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 DC transformer circuit is provided. A first end of an energy storage inductor in the DC transformer circuit is connected with a module output pin in a DC transformer module, and a second end of the energy storage inductor is connected to a grounded terminal. Using the DC transformer circuit can thus generate a negative voltage for a display device. Compared to a DC buck-boost circuit adopted in the existing arts, the DC transformer circuit has an advantage of low cost.

Abstract: The present disclosure provides a backlight module and a display device. The backlight module includes a control circuit, a power chip, and light emitting devices. The control circuit include a control signal input terminal, and when the control signal input terminal is in a suspended state, the control circuit can output an enable signal. An enable pin of the power chip receives the enable signal, so that the power chip controls an output of a power supply voltage under a control of the enable signal. The light emitting components receive the power supply voltage, and are driven by the power supply voltage to emit light.

Abstract: A backlight module and a display device are provided. The backlight module includes a plurality of light boards, wherein each light board includes at least two light source groups arranged at intervals. An overlap area of adjacent reflective sheets is located between adjacent light source groups in a same light board, and a splicing area of adjacent light boards is located in a non-overlap area of a same reflective sheet so that a protrusion of the reflective sheets in the overlap area will not reflect too much light to the splicing area, which solves a problem of uneven brightness at splicing positions of the light boards of current display products.
