Description

technical field [0001] The invention relates to the technical field of LED display, in particular to an LED display device. Background technique [0002] LED (Light Emitting Diode), a light-emitting diode, is a solid-state semiconductor device. Its function is to directly convert electrical energy into light energy and emit it. The heart of the LED is a semiconductor chip, and one end of the chip is attached to a bracket. , one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin. LED has the advantages of small size, low power consumption, long service life and environmental protection. With these advantages, a large number of LED related products have emerged. LED color curtain is one of these products. [0003] At present, most of the products in the LED industry are conventional single-sided LED displays. Due to the limitation of the viewing angle of the single-sided LED...
