[0025] Please see Figure 1-3 This utility model provides a technical solution: a hemispherical display device, including a base 1 and a face mask 2 matched with the base. The upper part of the base 1 has an integrally formed hemispherical body 11, on which several flexible LED light panels 3 are arranged in a fan shape. Each flexible LED light panel 3 together forms a hemispherical light-emitting surface and is electrically connected in series. Several LED beads 4 are integrated on the flexible LED light panels 3. A controller and a power supply are built into the bottom of the base 1, wherein the controller includes a control unit and a communication unit. The power supply is electrically connected to the controller and each flexible LED light panel 3. The control unit is the core control chip; the chip model can be selected according to the main functions of the control unit described herein, and no chip model is limited here. The fan-shaped arrangement of flexible LED light panels forms a continuous light-emitting surface, eliminating the seam problem of traditional planar splicing and achieving a seamless hemispherical display effect. The built-in controller and power supply: the integrated design reduces external cable interference and improves overall aesthetics and portability. To further improve the heat dissipation system design of this hemispherical display device, a graphene thermal conductive layer is added to the inner surface of the hemispherical body 11; the base 1 is equipped with an array of annular heat dissipation holes, which, together with a micro turbine fan, form an active heat dissipation channel; the flexible LED light board 3 adopts a copper-based copper-clad laminate structure and integrates a heat pipe heat dissipation unit.

[0026] The base 1 has a charging port 12 on its exterior. The charging port 12 is electrically connected to a power supply, which is a lithium battery. It supports direct charging, avoids frequent battery replacements, and enhances the device's sustainable usability.

[0027] The face mask 2 is a hemispherical transparent shell made of optical-grade polymethyl methacrylate or polycarbonate material, with anti-glare microstructures on its surface. The combination of optical-grade materials and anti-glare microstructures in the face mask 2 improves light transmittance while reducing light spots and reflections, thus optimizing visual comfort.

[0028] The radius of curvature of the flexible LED light panel 3 matches the radius of curvature of the inner surface of the mask 2. This matching of curvature between the flexible LED light panel and the mask ensures a constant distance between the LED beads and the mask, preventing light refraction distortion.

[0029] LED bead 4 is a full-color LED chip. It enables dynamic color display, expanding application scenarios such as ambient lighting and advertising displays.

[0030] The control unit is configured to: receive control commands transmitted via the communication unit; parse the control commands and generate corresponding LED drive signals; transmit the LED drive signals to each flexible LED light panel 3, controlling the LED beads 4 at specific locations to illuminate to form patterns or text. Precise zone control of the LED beads supports complex pattern / text display, improving interactivity and information transmission efficiency.

[0031] The communication unit includes a wireless communication module and a wired communication module. The wireless communication module includes a Bluetooth module and an infrared module, establishing a wireless communication connection with the mobile terminal. Wired / wireless dual-mode communication meets the needs of different scenarios; the Bluetooth / infrared module supports remote control from the mobile terminal, enhancing ease of operation.

[0032] During use, users send control commands via mobile terminals (phones / tablets), which are transmitted to the communication unit via Bluetooth / infrared modules. The control unit parses the commands in real time, generating corresponding PWM dimming signals and RGB color data. The drive signals are transmitted to each flexible LED light panel 3 in a sector-shaped partition, precisely controlling the brightness, color, and lighting sequence of the full-color LED beads 4 to form dynamic or static patterns or text. The series circuit between adjacent light panels ensures signal synchronization, forming a seamless hemispherical light-emitting surface. It is suitable for advertising displays, ambient lighting, and interactive information delivery scenarios.
