The invention relates to a Mini-LED / Micro-LED full-color display device based on a photonic crystal and a preparation method of the Mini-LED / Micro-LED full-color display device, and the Mini-LED / Micro-LED full-color display device comprises a driving substrate which is provided with a driving circuit; the light-emitting units of at least three colors are bonded to the driving substrate, each light-emitting unit is prepared by processing a blue light Mini-LED / Micro-LED chip, and each light-emitting unit comprises a buffer layer, an n-GaN layer, a blue light multi-quantum well layer and a p-GaN layer which are sequentially stacked; each light-emitting unit further comprises a control electrode, and the control electrode comprises a p-type electrode layer and an n-type electrode layer; each light-emitting unit can also be provided with a green photonic crystal structure or a red light body structure which penetrates through the buffer layer and extends to the n-GaN layer to form a green light-emitting unit or a red light-emitting unit, and the light-emitting unit without the photonic crystal structure is a blue light-emitting unit; the three adjacent light-emitting units arranged in the array include a red light-emitting unit, a green light-emitting unit and a blue light-emitting unit.

The invention discloses an interactive display screen for new media display, and relates to the technical field of interactive display screens. The device comprises a frame body, the surface of the bottom of the frame body is fixedly connected with the inner side face of a shell, a cleaning assembly is arranged on the side, away from a cooling assembly, of a screen, the cleaning assembly is fixedly connected to the bottom of the inner wall of the shell, and the side, close to the shell, of the cooling assembly penetrates through the frame body and extends into the shell. The surface of the cooling assembly is fixedly connected with the inner side face of the shell, the bent screen can provide a larger visual field range and provide a better visual interaction effect, the cleaning assembly cleans the screen in real time and keeps the screen clean, and the clean screen can enhance the interaction willingness of people and enhance the display effect; the screen is kept clean, oxidation or corrosion of the screen can be avoided, the display life is prolonged, the cooling assembly cools the back of the screen, and therefore the screen is prevented from being overheated and short-circuit damage of the screen is avoided.

The present application provides a flexible packaging structure, a flexible packaging method and a display device, wherein the flexible packaging structure includes a display substrate; a first inorganic packaging layer, which is arranged on the display substrate; an organic packaging layer, which is arranged on the first inorganic packaging layer, and the organic packaging layer includes flaky graphene oxide, which is staggered; and a second inorganic packaging layer, which is arranged on the organic packaging layer. The present application arranges flaky graphene oxide in the organic packaging layer on the first inorganic packaging layer, and the graphene oxide has hydrophobicity. The flaky graphene oxide is staggered, so that the flaky graphene oxide forms a "maze" blocking effect on water vapor and oxygen, thereby effectively extending the invasion path of water vapor and oxygen along the second inorganic packaging layer to the display substrate, reducing the risk of flexible packaging failure, and facilitating the increase of display life.

The application discloses a display panel, a protection method and a display device. The display panel comprises a temperature detection module, which is used for converting a temperature signal of the display panel into an electric signal; a control module, which is connected with the temperature detection module and is used for generating a control signal when the electric signal of the temperature detection module exceeds a preset value; and a protection module, which is connected with the control module and is used for performing overheat protection based on the control signal. The temperature detection module detects the temperature of the display panel by converting the temperature signal of the display panel into the electric signal, and outputs a corresponding control signal based on the result of the electric signal, so that protection control is performed based on the control signal, overheat protection is improved, and the protection effect and the display life of the display panel are improved.
