A display module and a driving method thereof, and a display device are provided. The display module includes a backlight structure including a plurality of backlight partitions. The display module includes a first display mode and a second display mode. Resolution of the display module in the first display mode is greater than the resolution of the display module in the second display mode. In the first display mode, a quantity of the plurality of backlight partitions of the backlight structure is n1, and an area of one of the plurality of backlight partitions of the backlight structure is S1. In the second display mode, the quantity of the plurality of backlight partitions of the backlight structure is n2, and the area of one of the plurality of backlight partitions of the backlight structure is S2, with n1>n2, and S1<S2.

Display module and driving method thereof, and display device

Provided is a pixel driving circuit. The pixel driving circuit includes a reset unit, a storage unit, an initialization unit, a drive unit, a threshold compensation unit, and a data write unit. A first terminal of the reset unit is configured to input the signal output by a reset power supply. A second terminal of the reset unit is connected to the control terminal of the drive unit and configured to provide the reset power supply for the control terminal of the drive unit during a power-on period. During the power-on period of the pixel driving circuit, the reset unit provides the reset power supply for the drive unit and performs reset control on the drive unit, so that the drive unit is prevented from being abnormally turned on during a power-on stage, thereby avoiding a screen flicker phenomenon.

Pixel driving circuit and driving method thereof, light-emitting panel, and display device

Provided are a driving substrate, a backlight, and a display device. The driving substrate includes a plurality of backlight partitions arranged in an array. Each of the plurality of backlight partitions is provided with a first pad set column and a second pad set column, where the first pad set column and the second pad set column comprise arranged along a first direction and each include a plurality of pad sets arranged along a second direction, where the first direction intersects with the second direction. A boundary on one side of the first pad set column facing away from the second pad set column is denoted as a first boundary, and a boundary on one side of the second pad set column facing away from the first pad set column is denoted as a second boundary.

Driving substrate, backlight, and display device

A multipath selection circuit includes a first data line, a second data line, a third data line, a control line, a timing line, a switch circuit, and a drive circuit. The drive circuit includes a first switching transistor and a second switching transistor. The switch circuit is configured to receive a control signal, timing signal, first data signal, second data signal and third data signal, and operate in a first operating mode or a second operating mode according to the control signal and the timing signal. In the first operating mode, the switch circuit is configured to transmit the second data signal to the first switching transistor and the second switching transistor in a time division manner; and in the second operating mode, the switch circuit is configured to transmit the first data signal to the first switching transistor and the third data signal to the second switching transistor.
