outdoor DIP virtual pixel full color
LED display is designed specially for outdoor high-definition display. It adopts the virtual pixel technology, which in essence is the technology using the phenomenon of human eye's persistence of vision and reusing the real pixel separately to reappear more information points (virtual pixel), namely pixel-sharing technology. It is the newest LED technology and control technology. It makes the full color LED display have lower price, stable performance, lower power consumption, high resolution per unit, vivid color. It also makes the full color LED display have fewer electronic components when composing the system. Thus it decreases the failure rate. Our company adopts the 2R1G1B pixel. The common pixel is used four times while displaying the picture. In the premise of the same display size and optical materials, the virtual pixel has the display point up to 4 times more than real virtual and can express more information.
What is virtual pixel?
1. Definition of the virtual pixel:
The display elements of each point of the red, green and blue in the display unit is distributed uniformly. In order to coordinate with the blending effect of the pixel, the characteristic color of the virtual display point is a mixture of the adjacent red, green and blue pixel.
The point of the virtual pixel is dispersive, while the real one is cohesive. The luminous point of the virtual pixel is in the tube, but the real one is in the lamp.
2. How to calculate the number of LED tubes corresponding to the real pixel?
When the R、G、B is disturbed with the number of 2、1、1, a pixel is consisted of two red tubes, a green tube and a blue one.
When the R、G、B is disturbed with the number of 1、2、1, a pixel is consisted of a red tube, two green tubes and a blue one.
So the calculation of the numbers of the real LED tube is to use pixel points to multiple (2 +1 +1) or (1 +2 +1).
3. Realization method of the virtual pixel
When the light board is disturbed with 2 red, 1 green and 1 blue, and if it is real pixel and the dot matrix is 3x5, thus the conversion relation is as follows: M=2N-1 M: virtual pixel point; N: real pixel point (when it is single row or single line).
4. How to calculate the number of LED tubes corresponding to the virtual pixel?
Because the virtual pixel has no pixel points and only the virtual pixel points, so the number of the virtual pixel 's LED tube is the specific number of the RGB tube.
5.Why to use virtual pixel?
★ Improving the display performance: The display effect of the virtual pixel is four times better than real pixel.
★ Decreasing greatly the price of whole display screen: It can save a quarter of the tube in the same resolution when using the virtual pixel. Besides, it can achieve the equal virtual effect of the real virtual. Presently the main cost of the virtual SMD full color large display screen is on the tube.
★ Using the virtual pixel can decrease the fatigue while watching the display, because the more even the lighting points are disturbed, the more even the glow will be in the same size, it will lower the fatigue while people watch the screen. Virtual pixel is the most advanced LED display technology in the world now. Using the virtual pixel means walking in the forefront of the world.
