Brief introduction of High brightness all-colors LED video display:

1.High brightness all-colors LED video display (outdoor) has the characteristics hereinafter except the indoor¡¯s:

• High brightness The outdoor is desired to be view in the condition of plenty sunshine ,the brightness is demanded to exceed 4000mcd/M 2,It is well considered in LED wafer¡¯s chosen, encapsulation of pels ,drive mode, technique structure.

• Improvement of the interlink mode inside the display board. The outdoor pin-type mode group reduces 3-4 time of screen body weight and volume than the traditional cylinder-type encapsulating designment.

• Assemble pels designment.

85% of the efficacy consume of screen is transformed to light energy. Loss only 10%¡ª15% efficacy consume.No obvious warm up in the electric circuit. More stable and reliable increasing the longevity of screen .

• Perfect system structure .

Perfect technique structure, achieve the light weight ,thin screen board ( 5CM )and dustproof and waterproof purpose . The whole screen is provided with three defend capacity , The display board can be cleanout by water ,doesn¡¯t influence the electric circuit .

2. Function characteristic :

It has the characteristics hereinafter except the indoor Double color Basic Display system :

• High brightness ,can reveal various of chart, text and images in focus in the sun. Working the whole day .

• Compatible with the PC software ,synchrony with PC and CRT ,can play and edit various of picture of multimedia and TV .

• Temperature of screen is under 40ºC, aeration in gear ,no need air-condition .

• The Whole screen radiate pipe adopts the constant current mode .static lock up memory drive .

• Waterproof ,hurricane lamp , anti-thunder, anti-disturb of industry .

• No mosaic in the whole screen .the install error between display boards ©‚ 2MM ,install distance between modules ©‚ 2MM ,unlever of Whole screen ©‚ 5MM

• Standard design ,easy install ,easy maintenance .

• The electric capacity according to the international standard .

• High stability ,high reliability, low heat ,low efficacy consume, longevity is more the 10 years.
