Abstract: A light-emitting substrate includes a substrate and a plurality of light-emitting assemblies. The plurality of light-emitting assemblies are located on a side of the substrate. At least one light-emitting assembly includes a light-emitting element and a light adjustment portion arranged around the light-emitting element. The light adjustment portion includes a plurality of sub-structures spaced apart from each other. In any two sub-structures in the light adjustment portion in any direction away from the light-emitting element, a height of a sub-structure closer to the light-emitting element is less than a height of a sub-structure farther from the light-emitting element.

Abstract: Embodiments of the present disclosure provide a connector for a display device and a relevant display device. The connector includes an input cable interface for connecting an input cable to receive an input mixed signal, a signal processor for processing a first signal in the mixed signal received via the input cable interface to obtain a video signal for display, a signal separator for separating a second signal from the mixed signal and to generate a DC voltage based on the second signal, a video signal output interface for connecting a display interface of the display device to output the video signal, and a power output interface for connecting a power supply interface of the display device to output the DC voltage generated by the signal separator to the display device. Externally-connection interfaces and connection wires are reduced by using one cable to transmit signals of multiple properties.

Abstract: A double-sided display device includes: a first display layer, configured to implement output of a display signal of a first side; and a second display layer, configured to implement output of a display signal of a second side; a conversion layer positioned between the first display layer and the second display layer, which switches between a light-transmitting state and an opaque light-shielding state. The conversion layer is in the light-shielding state during a display phase, and in the light-transmitting state during an interfering phase which follows the display phase. During the interfering phase, the first display layer is further configured to output a first interfering signal to interfere with the image displayed by the second side, and the second display layer is further configured to output a second interfering signal to interfere with the image displayed by the first side.
