    Abstract: A backlight module includes a substrate provided with a light-emitting region and a bonding region, a plurality of light-emitting units disposed on a side of the substrate, a back plate disposed on the other side of the substrate, and at least three drive circuit boards bonded and connected to the bonding region by first connectors. Moreover, an extension direction of a long edge of each of the light-emitting units is not parallel to a bonding edge of the bonding region. In this way, when the back plate is a curved back plate, the risk of peeling of the light-emitting units from the substrate when the back plate is in a curved state can be reduced by flexibly setting the degree of the included angle between the extension direction of each long edge of each light-emitting unit and the bonding edge of the bonding region.

    Abstract: Disclosed in the present application are a display substrate, a preparation method therefor, and a display device. The display substrate includes a rigid substrate, and a flexible film layer and a display function layer that are sequentially stacked on the rigid substrate. The rigid substrate is provided with an opening at a bending region to expose the flexible film layer in the bending region. The display substrate further includes a first light absorption portion in a display region and is on the side of the display region close to the bending region. The first light absorption portion is on the side of the rigid substrate facing away from the flexible film layer or is between the rigid substrate and the flexible film layer.

    Abstract: A shift register (SR) includes a voltage control circuit (110) and a bias compensation circuit (120). The voltage control circuit (110) is configured to control a voltage at a first node (Output) to be a first voltage or a second voltage. The bias compensation circuit (120) is configured to: when the voltage at the first node (Output) is the first voltage, transmit a first signal received by a first signal terminal (VDD-A) to a first signal output terminal (EM1), and transmit a second signal received by a second signal terminal (VDD-B) to a second signal output terminal (EM2); and in response to the voltage at the first node (Output) being the second voltage, transmit a signal received by a first voltage terminal (LVGL1) to the first signal output terminal (EM1) and the second signal output terminal (EM2).

    Abstract: Disclosed is an array substrate including multiple first selection circuits with each including at least two first selection transistors and at least two first anticreeping transistors. Each first selection transistor is connected with one first anticreeping transistor in series. When the first selection transistor is turned on by a first turn-on signal from a first control signal terminal, the first anticreeping transistor is turned on by a second turn-on signal from a second control signal terminal. When the first selection transistor is turned off by a first turn-off signal from the first control signal terminal, the first anticreeping transistor is turned off to make the first selection transistors and the data signal terminal disconnected, by a second turn-off signal from the second control signal terminal. A voltage of the first turn-off signal is greater than a voltage of the second turn-off signal.
