Abstract

The embodiment of the invention provides an LED display screen and a control system thereof, and belongs to the technical field of LED display screens. The control system comprises a system control circuit, an LVDS interface bus driver, an LVDS bus receiver and a light bar control circuit; the system control circuit outputs TTL / COMS signals to the LVDS interface bus driver; the LVDS interface busdriver converts the TTL / COMS signal into a low-voltage differential signal, and transmits the low-voltage differential signal to the LVDS bus receiver; and the LVDS bus receiver converts the low-voltage differential signal into a TTL / COMS signal, and transmits the TTL / COMS signal to the light bar control circuit. By the adoption of the system, high-bandwidth long-distance transmission of control signals is achieved, the transmission distance can reach hundreds of meters, when the system is used for outdoor curtain wall and landscape lighting, the system control box can be easily placed indoorsto be installed, long-term operation is safer and more reliable, and indoor maintenance is safer and more convenient.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of LED display screens, in particular to an LED display screen and a control system thereof. Background technique [0002] LED (light emitting diode, light emitting diode) display screens have the advantages of low power consumption, high power, and long life, and are widely used in various fields. There are many types of LED displays, such as LED light bar display is one of them, which has the advantage of scattered display according to the local position of the building structure, so it is often used for outdoor curtain walls and landscape lighting. [0003] However, conventional LED light bar displays can only transmit TTL / COMS (Transistor-TransistorLogic / Complementary metal-oxide-semiconductor) signals at short distances, and the transmission distance is less than 5 meters. At present, some LED light bar displays on the market use MAX485 communication for long-distance transmis...
