Abstract

The invention relates to the technical field of electronic information display, in particular to a control system for an LED display screen. The control system can utilize a multi-type interface control module and an LED display screen blocking display control system and comprises the LED display screen blocking display control system, a display screen internal control bus and the multi-type interface control module, wherein all parts of the system are connected together through the display screen internal control bus; the LED display screen blocking display control system comprises an LED display module and blocking display control boards; the multi-type interface control module wirelessly controls a 433M wireless module, a Bluetooth module and a WIFI module in a short distance, is converted into a differential control bus through a converter and is connected to the display screen internal control bus; the multi-type interface control module wirelessly controls a GPRS (general packet radio service) module, an EDGE (enhanced data rate for GSM evolution) module, a CDMA (code division multiple access) module, a 3G CDMA2000 module, a 3G WCDMA (wideband code division multiple access) module, a TD-SCDMA (time division-synchronization code division multiple access) module, a 4G LTE-FDD (long term evolution-frequency division duplex) module and a 4G TD-LTE (time division long term evolution) module in a long range, is converted into the differential control bus through the converter and is connected to the display screen internal control bus.

Description

technical field [0001] The invention relates to the technical field of electronic information display, in particular to an LED display screen control system. Background technique [0002] At present, the LED display control system consists of a master-controlled LED display, a display interface and a host computer (desktop or laptop computer running special LED display playback editing control software). [0003] Scanning display technology is widely used in LED display screens. The indoor display is 1 / 8 or 1 / 16 scan, the outdoor display is 1 / 4 scan, and a scan cycle is less than 13ms. The LED display is composed of LED display module, main control panel and power supply. The LED display module is composed of LED display array, drive interface and row and column drive circuits. Due to the high-density dot matrix display and refresh rate requirements, the 128-byte column drive data must be transmitted within 0.5ms, and the frequency of the shift pulse signal received by th...
