Description

Very large-display screen control method and device thereof that a kind of luminotron is formed

Technical field

The invention belongs to the dynamic display screen technical field, specially refer to and use very large-display screen, control method and the device thereof of luminotron as light-emitting component.

Background technology

At present, in the technology of existing screen display, there are two kinds: a kind ofly forms the screen display that another kind of employing LED light emitting diode is made by a plurality of televisors for the ultra-large type screen.Televisor is by kinescope, tuner, electronic control circuit, the power control part composition that grades, it is suitable for indoor, in-plant use, and for being applied to the station, the square, the harbour, big waits, Waiting Lounge, advertisement such as stadium and street, prompting, the ultra-large type screen of information issue is to adopt a plurality of televisor matrix combinations, and television picture tube becomes the light-emitting component of ultra-large type screen, as everybody knows, its imaging is that the bright spot instantaneous light emission by matrix forms, its line frequency is 64us, every scanning one frame is 625 row, time is 64 * 625=40ms, and bright spot is only lighted once by the electron beam triggering in 40ms, because the twilight sunset effect of fluorescent powder can be delayed time about 5ms when lighting, extinguish immediately, all the other 35ms times, bright spot stops luminous, only is to keep continuous dynamic process by people's persistence of vision effect.It not too is adapted to the use in big place, and its luminosity is relatively poor to the long distance vision effect.

In recent years, in the jumbotron technical field, adopted the screen of LED collection of leds matrix, and control method and devices such as screen circuit, control circuit and power circuit.It is the point light source light-emitting element in the screen matrix with LED, because the characteristic of LED element causes the surplus light hangover of the screen that is combined oversize.With the small screen LED Chinese character advertisement machine is example, and its concrete weak point has:

1, LED array light source, dot matrix is 16 * 128, dynamic scan drives line by line, with big current scanning pulse LED is directly powered, because the scanning impulse narrower in width is no more than the 1ms time, adopts 16 bit shift storeies to make luminous point repeat to light 128 times, just obtain every capable 3.5ms light time, its luminosity factor is very low.

2, the luminosity of LED luminotron can not be adjusted.Produce the snowslide conducting and light when the rated voltage 2-2.5V of regulation, be lower than this voltage and do not work, being higher than this voltage brightness does not increase, owing to there is not the variation of luminance level, makes the color dullness of screen display, and general screen has only red, green, orange three looks.

For a long time, seek in the art always a kind of new be suitable for that big place uses can satisfy that picture and text show and luminescence efficiency height, good brightness, can light modulation, toning, the jumbotron that remote display resolution is high and the method for luminotron grouped controls and control thereof.

Summary of the invention

The object of the invention is to overcome LED and is applied in weak point in the giant-screen, provide a kind of new be suitable for that big place uses can satisfy that the picture and text image shows and luminescence efficiency height, luminance brightness good, can light modulation, toning, remote high jumbotron control method and the control device of display resolution, and the control device of luminotron combination.
