2. Beautiful appearanceand innovation design

The 2th generation of Crystal compass P3.91 is the new indoor LED display that innovative research and design by SBC in 2014. The appearance and inner structure were rigorously designed through strict considerations, out shape is refinement and atmospheric novel, super slim design with die cast aluminum, independent power supply box can be easily replace and maintenance. Reasonable Internal structure and layout , good heat dissipation, use safety. Curve handle designed base on Ergonomics, not only beautiful and strong, and easy installation and removalNo need tools, the locks can be fast assemble and disassemble. It can be fast and convenient to maintenance by front and back these two maintenance way if come malfunction during use. Invisible data connection, no need cables. Installation and data connection can be done in one step. It breaking the traditional design concept from in and out, its a good and rare product to customers.

Function Advantage

Increase the power factor trough Reduce switching power between the fundamental current and voltage AC input phase difference, the power factor of this kind of poweris more than 98%, efficient can be 90%It can save your energy loss (Average power consumption is 460W/m only), improve the electric using efficient, so that save your cost.

The harmonics of didnt use PFC power The harmonics with PFC power

2Gamut conversion

Gamut conversion: When a part of LED display appears unreal natural phenomena, using the light gun to get the original color gamut, converted to what you want to achieve. So this kind of color is more close to real and natural

3Batch Match

Batch Match: When there are different batches LED lamp in one screen, image effect is bad, batch match collection LED light, Chroma, wavelengthAnd then find the common gamut and adjust them to the same, so we can use different batches in one LED display.

After

Gamut conversion:When a part of LED display appears unreal natural phenomena, using the light gun to get the original color gamut, converted to what you want to achieve. So this kind of color is more close to real and natural

4: No Ghosting

Normal LED displayGhosting is very bad, image is filmy , there is twilight when testing.

SBC LED products use recharged function LED driving ICCompletely eliminated, there is no twilight between testing line.

Technical advantage

5 High Contrast

With mask(Black)

No mask (Gray)

White and black, contrast rate

Test formula: (Screen brightness environment brightness)/ environment brightness

Only SBC LED product have black mask processing technology, let LED screen get high contrastBlack mask also can improve LED light lighting tidy degree, reduce side emitting factor, so the screen can get uniform brightness

16

Technical advantage

6. High refresh rate: 1500Hz can be adjust

SBC LED screen use the leading technology, dynamic scanning method, refresh rate is higher than 1000HzThere is no wave line when display videos, can satisfy the high end occasion, perfect match the atmosphere

High refresh rate 2440Hz, image is stable and clearCamera Canon shutter speed 1/1250s

Refresh rate 300~600Hz, image is flashing Camera Canon shutter speed 1/1250s

8. Perfect assembly effect

SBC LED screen can be assembled by any shape, transcend DLP and MLCD, split situation will not come out, ensure the image display perfect.

Pixel pitch will become to 9.2mm

Miss pixel pitch

There are big gaps between DLP when assembling,

the pixel pitch will bigger, pixels are changed, image will not the same

1.25mm 1.25mmPixel pitch still 2.5mm

Gap is 0mm, not misspixel pitch

When SBC product assembling, the gap between Each pixel still is 2.5mm, 2.5mm1.9mmPixel is uniform distribution, image is complete and vivid.
