The utility model content

The fundamental purpose of the utility model is to overcome the deficiency of prior art, and a kind of LED display with the intelligent time-control device is provided, the single line transmission; Reduce cost, the circuit self check reduces circuit and damages; Can set service time; Make things convenient for use and management, penetrating structure makes on the basis that does not influence visual range and radiating effect, has increased the steadiness and the dirigibility of LED display.

For realizing above-mentioned purpose, the utility model has adopted following technical scheme: a kind of LED display with the intelligent time-control device, form by screen body, a plurality of led module, intelligent time-control device; The intelligent time-control device comprises authentication module, time detecting module, locking module, processing module and drive control module, and authentication module is used for receiving and verifying outside input information, when input information is effective; Send start signal to open processing module, the time detecting module is used to detect the effective time of input information, when external time arrives Preset Time; Full signal is to locking module during transmission, locking module be used for according to the time full signal, generate locking signal; Send to processing module with the locking processing module, processing module is used for incoming video signal, under unlocked state; Receive said start signal, handle said vision signal, generate drive control signal; Send to drive control module, drive control module is used for according to drive control signal, with each outside LED of drive controlling; Led module comprises at least one LED luminophor, circuit board substrate, and the LED luminophor is fixed in the circuit board substrate top layer, and circuit board substrate comprises a cathode power supply circuit, a negative power supply circuit, an operation circuit, transmission control chip; The positive and negative power supply circuit is connected with transmission control chip; Transmission control chip is luminous according to the signal controlling LED luminophor of operation circuit input, and circuit board substrate also is provided with a detecting unit, is used for detection line paths of LEDs line temperature; When the LED line temperature surpasses preset temperature, cut off the electricity supply automatically with LED between be connected;

The circuit board substrate another side is the insulating radiation layer, and circuit board substrate is arranged with through hole in the situation that does not influence normal use, is used for absorbing as soon as possible heat;

The LED luminophor is arranged side by side on the circuit board substrate with bar shaped, and two adjacent circuit board substrates are arranged in parallel, and forms penetrating space;

The screen body is plastic cement screen body or alloying metal screen body;

Circuit board substrate is aluminium base, titanium alloy substrate, magnesium alloy substrate, aluminium alloy base plate, copper base or ceramic substrate.

Can realize the self check of LED display circuit through technique scheme, avoid line temperature too high, cause damage; And LED display is the single line transmission; Reduce cost, can set service time, make things convenient for use and management; Penetrating structure makes on the basis that does not influence visual range and radiating effect, has increased the steadiness and the dirigibility of LED display.
