1.What is the difference between real pixel LED display and virtual pixel LED display ?
With the virtual pixel technology, the outdoor led display screen will appear a more clear vision. Theoretically the resolution will be 4 times of a real pixel technology outdoor led display screen .The difference of a real a virtual pixel outdoor led display 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 outdoor led display screen , 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 outdoor led display screen have a horizontal viewing angle of upto 130 degrees.
3. What is the refresh rate for LED screens?
The refresh rate of a outdoor led display screen 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 outdoor led display screen 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 outdoor led display screen , 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 outdoor led display screen , damage to the display can occur.
Normally our outdoor led display screen 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 outdoor led display screen 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.
