[0002] An LED display unit board mainly consists of LED light-emitting diodes, driver circuits, driver ICs, and plastic components. The LED light-emitting diodes are the core component of the display unit, responsible for emitting light and displaying the image; the driver circuits and driver ICs are responsible for controlling the LED's luminous state and brightness; and the plastic components protect and secure the LEDs and other components.
[0003] Wide-angle LED displays are widely used for advertising in commercial venues such as shopping malls and supermarkets. The heat generated during the use of multiple unit boards is easily expected to accumulate inside the device. Therefore, the device needs to be used in conjunction with a heat dissipation device. Currently, the mainstream heat dissipation device is air cooling, which uses cold air to blow directly onto the unit boards inside the device. As a result, the heat dissipation effect of the unit board depends on its distance from the air inlet, and the heat dissipation effect is very poor, which has certain shortcomings. To address this, we propose a wide-angle viewing angle optimization LED display unit board. Utility Model Content
