Abstract: The present disclosure discloses a driving circuit and a display panel. The driving circuit includes: a first wire; a second wire; and a plurality of third wires, spaced apart from each other, wherein one end of each third wire is electrically connected to the first wire, and an other end of the each third wire is electrically connected to the second wire. A current adjustment unit and at least one light-emitting unit are disposed on the each third wire. Each current adjustment unit has a different resistance value. The current adjustment unit on the each third wire that is farther away from a first signal input terminal of the first wire has a smaller resistance value.

Abstract: A backlight driving method and a display panel are provided. The backlight driving method provided by the present application uses pulse width modulation technology to modulate a low-level pulse width of a scan signal. By increasing a low-level pulse width to increase the pulse period, a number of high-level pulses is reduced, thereby reducing a high-level pulse time. Therefore, a time for a TFT to receive a high-level voltage is also reduced, thereby improving a stability of the TFT and also improving a problem of a threshold voltage drift of the TFT.

Abstract: A display panel and a display device are provided. A sub-pixel unit of the display panel includes at least one light-transmitting region, and each light-transmitting region is provided with at least one driving transistor. At least part of a source wiring of the driving transistor is disposed at a boundary of the light-transmitting region and parallel to an extension direction of data signal lines, and a drain wiring is disposed in the light-transmitting region. The light-transmitting region of the sub-pixel unit occupied by the driving transistor is reduced to alleviate a problem of low aperture ratio of a backplane of current display products.
