Function and Technology Character
1) To ensure the clearness of graphics and texts, as to the indoor display within 100sqm,the same level of red,green and blue LED lamps with the same brightness( ±10%)and wave length( ±2.5nm) are chosen.

2) The glue we apply to encapsulate the module surface is imported from Sourth Korea. It decreases the effect of background color. As a result of the full absorption of thr LED refraction light,the display eliminate the urmbra and ghosting during broadcast.

3) We apply sophisticated technology of plastic closure,each module of the horizontal height less than 0.1mm. Therefore,our displays have good color uniformities ,homogeneity,which is unique in the LED display field.

4) Module design makes it convenient to assemble and also ensure that the cabinets are nice-looking.

5) Maitenance difficulties are slolved and it truely realizes three-dimensional and dot-to-dot maiterance.

6) The price is competitive among the same products in market and the quality is assured.

1. What is the difference between real pixel LED display and virtual pixel LED display ?
With the virtual pixel technology, the LED display will appear a more clear vision.
Theoretically the resolution will be 4 times of a real pixel technology LED display.
The difference of a real a virtual pixel LED screen of LED display can be seen in the next pictures.

2. How do virtual LED display work?
Below you can clearly see how the virtual pixels are made, we surely recommend you a virtual display, even so our new technology of Dot Matrix it’s still better than virtual pixels, because the three colors RGB are in the same dot or pixel, just like the SMD technology and also the Dot Matrix have a horizontal viewing angle of over 160 degrees. The virtual pixel LED display have a horizontal viewing angle of upto 130 degrees.

3. What is the refresh rate for LED screens?
The refresh rate of a LED display is the number of times in a second that the LED display hardware draws the data. This is distinct from the measure of frame rate in that the refresh rate for LED display includes the repeated drawing of identical frames, while frame rate measures how often a video source can feed an entire frame of new data to a display.For example, most movie projectors advance from one frame to the next one 24 times each second. But each frame is illuminated two or three times before the next frame is projected using a shutter in front of its lamp. As a result, the movie projector runs at 24 frames per second, but has a 48 or 72 Hz refresh rate.

4. Increase refresh rate for decreasing LED screen flickering
On LED display, increasing the refresh rate decreases flickering, thereby reducing eye strain. However, if a refresh rate is specified that is beyond what is recommended for the LED display, damage to the display can occur.
Normally our LED display have a refresh rate of over 300Hz, which is more than 5 times the refresh rate of a normal cathode television which is 50Hz (PAL and SECAM) or 60Hz (NTSC). For football stadiums (stadium LED display and perimeter LED display ) our LED display can reach a refresh rate of over 800Hz, which means that they won´t show any flickering when recorded with a video camera and broadcasted live on television.
