The light-emitting chip comprises a first protective layer, a second protective layer and a first electrode, a second protective layer; the first electrode layer is arranged between the first protection layer and the second protection layer, and the two ends of the first electrode layer are connected with the first protection layer and the second protection layer respectively; the second electrode layer is arranged between the first protection layer and the second protection layer, the second electrode layer and the first electrode layer are arranged in a spaced mode, and the two ends of the second electrode layer are connected with the first protection layer and the second protection layer respectively; a first semiconductor layer, a light-emitting layer and a second semiconductor layer are sequentially arranged in a gap between the first electrode layer and the second electrode layer, and the first semiconductor layer, the light-emitting layer and the second semiconductor layer are all connected with the first protective layer and the second protective layer; a fool-proof structure is arranged on the side, away from the light-emitting layer, of the first electrode layer and / or the second electrode layer. According to the light-emitting chip provided by the invention, the accuracy and the stability in the chip transfer process can be improved.

The invention discloses a display panel and a display device. The display panel comprises a substrate; the light-emitting layer is arranged on one side of the substrate and at least comprises a first sub-pixel and a second sub-pixel, the first sub-pixel and the second sub-pixel are arranged in the direction parallel to the substrate, the first sub-pixel emits light in the direction deviating from the substrate, the second sub-pixel emits light in the direction pointing to the substrate, the driving layer is arranged between the substrate and the light-emitting layer, and the driving layer is arranged between the substrate and the light-emitting layer. Comprising a driving circuit, and the driving circuit is configured to be capable of driving the first sub-pixels and the second sub-pixels to emit light alternately. According to the display panel, double-sided display can be achieved, and the display quality of the display panel can be guaranteed.

The application discloses a display panel and a display device. The display panel comprises a substrate, a light-emitting device layer and a first reflection layer. The light-emitting device layer is formed on one side of the substrate and comprises a plurality of light-emitting units. The light-emitting unit has a light-emitting side and a backlight side arranged oppositely. The first reflection layer is formed on the side of the light-emitting device layer away from the substrate and comprises a body part and a plurality of first openings. The first openings expose part of the light-emitting units. The body part is used for reflecting part of the light emitted from the light-emitting side to the backlight side to form double-sided display. The display panel provided by the application can realize double-sided display and has simple structure and low cost.

The invention provides a display panel and electronic equipment. The display panel includes a light emitting unit, a light conversion layer, and a liquid crystal unit. The light-emitting unit comprises a first light-emitting surface and a second light-emitting surface which are opposite to each other, and the first light-emitting surface and the second light-emitting surface can emit first light. The light conversion layer is arranged on one side of the second light-emitting surface, and the light conversion layer can absorb the first light emitted by the second light-emitting surface and emit second light. The liquid crystal unit is arranged on the side, away from the second light-emitting face, of the light conversion layer and used for blocking the second light or emitting the second light out. The light conversion layer is used for absorbing the first light of the light emitting unit and emitting the second light to serve as backlight of the liquid crystal unit, so that the display panel achieves double-face display, the front display face and the back display face are used at the same time, the one-screen double-purpose effect is achieved, the structure is simple, the cost is low, the use scene can be further enriched, and the application prospect is wide. And the requirements of numerous special occasions are met.
