As blue, of the price of green glow diode reduce, indication technology of LED full prize is entered stage by stage practical change level, have the tendency that becomes LED quickly to show screen market main trend. Especially indoor the demand of full prize indication screen is in swift and violent expand, but former some is indoor full prize indication craft is paid no attention to in a lot of crucial index want, restricted indoor the use of full prize indication screen. Recently, inferior the full prize that the watch sticks shows screen compares the reception that gets the market greatly with superior sexual value, our company wish and broad person of the same trade popularizes this one project jointly together, develop jointly, be benefited jointly.

Target of serial number item
1 density resembling element 17200 bits / square metre
2 composition resembling element 1 red 1 green 1 blue
7.62mm of 3 span resembling element
4 indication unit board dimension 488mm*244mm
5 indication unit board like element 64 bits of *32 are nodded
6 brightness are not less than 4000cd/ square metre
Line of travel of 7 drive fashion: 1/8 scanning drive (introduce 4953 shunt-wound drive) line line: Constant current source (use Toshiba 62726 series integrated circuit)
550w of 8 average power comsumption
9 brightness consistency > 95%
10 perspectives > 160 degrees
11 image adjust Bai Pingheng, brightness is adjustable
12 consecutive working hours > 24 hours
256 class gray scale shows visual sense of support of 13 gray scale

Technical advantage is commented
Existing and common indoor the comparison of full color scheme:
1. Plan of latticedot matrix module: The earliest design program, develop by screen of lattice of indoor bogus colour and come
Advantage: Raw material cost has an advantage most, and manufacturing treatment craft is simple, quality is stable.
Defect: Colour consistency is poor, mosaic phenomenon is more serious, indication effect is poorer.

2. Simple tube plan: To solve problem of colour of latticedot matrix screen, draw lessons from outdoors a kind of plan of indication screen technology, resemble outdoor element answer using a technology at the same time (make share a technology like element again, fictitious technology resembling element) transplanting arrived indoor indication screen.
Advantage: What colour consistency compares pattern of latticedot matrix module is good.
Defect: The effect that mix scene not beautiful, the perspective is not big, water square watchs coloured to differ to the left and right sides. Treatment is more sophisticated, refuse electrostatic demand tall. It is more difficult to accomplish 10000 bits of aboves actually like element resolution.

3. Stick a plan: Adopt the plan that sticks a glow canal to be indication component.
Advantage: Colour consistency, the main indication index such as the perspective is existing plan in a best kind, especially the effect mixing scene that three-in-one watch sticks is first-rate.
