[0026] In one embodiment of this utility model, such as Figures 1-3As shown, an automotive pixel screen is provided, including a housing 1, a circuit board 2, LED beads 3, a mesh display cover 4, a diffusion film 5, and a PC board 6. The circuit board 2 is fixedly connected to the housing 1, and the LED beads 3 are electrically connected to the circuit board 2. The mesh display cover 4 is connected to the housing 1 and is disposed on one side of the LED beads 3. The mesh display cover 4 has a mesh structure 41, which is disposed on one side of the LED beads 3. The diffusion film 5 is disposed on the mesh display cover 4, and the PC board 6 is disposed on one side of the diffusion film 5 and fixedly connected to the housing 1. The circuit board 2 is the core control part of the entire pixel screen. On the one hand, it is connected to the vehicle's power system to obtain power supply, providing the energy basis for the operation of the entire pixel screen; on the other hand, it receives image signals and control commands sent from the vehicle's central control system or other related control systems. These signals and commands contain various information such as the image content to be displayed, brightness adjustment, and color mode. The circuit board 2 converts the received electrical signals into driving signals suitable for the operation of the LED beads 3. Under the action of the driving signals, the LED beads 3 emit light of different intensities and colors according to different driving current magnitudes. LED beads 3 have advantages such as high luminous efficiency, fast response speed, and long lifespan. They can quickly and accurately emit light according to the instructions of the circuit board 2, providing the light source foundation for image display. The light emitted by LED beads 3 passes through the grid display cover 4. The grid display cover 4 presents the light emitted by each LED bead 3 individually through the grid structure 41. Then, the microstructure of the diffusion film 5 presents the effect of each LED bead 3 more evenly to form an image. The PC board 6 serves as the support and protection structure for the entire pixel screen. On the one hand, it provides stable physical support for the diffusion film 5 and the preceding grid display cover 4, LED beads 3, and other components, ensuring that they maintain a relatively fixed positional relationship during vehicle operation. On the other hand, the PC board 6 also plays a certain role in electromagnetic shielding and insulation, preventing external electromagnetic interference from affecting the internal circuitry of the pixel screen, while ensuring the safety and stability of the circuitry and avoiding faults such as short circuits.

[0027] In another embodiment of this utility model, multiple LED beads 3 are provided and uniformly fixedly connected to the circuit board 2, and all multiple LED beads 3 are electrically connected to the circuit board 2. Each LED bead 3 can be regarded as a pixel or a component of a pixel. A large number of LED beads 3 are evenly distributed and can be densely arranged to form a high-resolution display screen.

[0028] In another embodiment of this utility model, the grid structure 41 is fixedly connected to the grid display cover 4, and the grid structure 41 is composed of multiple square grids evenly arranged; the square grids are arranged parallel to and opposite to the LED beads 3. The light source emitted by the LED beads 3 passes through the grid display cover 4, and the grid display cover 4 presents the light source emitted by each LED bead 3 individually through the grid structure 41.

[0029] In another embodiment of this invention, the diffusion film 5 is fixedly connected to the mesh display cover 4, and the diffusion film 5 is a microstructured light diffusion film 5. The microstructured light diffusion film 5 can change the propagation direction of light, allowing the light to scatter over a wider angular range.

[0030] In another embodiment of this utility model, the PC board 6 is fixedly connected to the housing 1, and the PC board 6 is made of transparent material. The transparent material of the PC board 6 allows the light emitted by the LED beads 3 and processed by the mesh display cover 4 and the diffusion film 5 to pass through to the maximum extent, ensuring that the brightness and clarity of the screen display are not affected.

[0031] In another embodiment of this utility model, the side of the housing 1 is provided with a positioning groove 11, and the circuit main board 2, the mesh display cover 4, the diffusion film 5 and the PC board 6 are all fixedly installed in the positioning groove 11.

[0032] In another embodiment of this utility model, a protrusion 12 is fixedly connected to the side of the housing 1. Two protrusions 12 are provided and arranged in parallel opposite directions. The housing 1 is fixed to the car glass by the protrusions 12.

[0033] The automotive pixel screen provided in this application emits light through LED beads 3 after being powered on. The light then passes through a grid display cover 4, which uses a grid structure 41 to individually display the light emitted by each LED bead 3. The microstructure of the diffusion film 5 further evenly displays the effect of each LED bead 3 to form an image. The image information can clearly indicate the vehicle's specific driving plan to pedestrians or other vehicles, avoiding misunderstandings and traffic confusion, reducing the potential risk of traffic accidents, and thus enabling the display of more information and achieving effective interaction between the vehicle and external traffic participants.
