LED is “Light Emitting Diode”, the smallest unit is 8.5 inch, can pixel maintenance and unit module change, LED life time more than 100,000 hours.

DLP is“Digital Light Procession” the size about 50inch~100inch，life time about 8000 hours. need wholesale replacement if projecting bulb and panel have problem.

1. Environmental adaptability of brightness

DLP\LCD display brightness is not high. Ambient brightness is strictly limited；unsuitable high brighness office or control room environment. 

LED display brightness could adjust between 600-1500cd，suit for various environment.

2. Reflective phenomenon

LCD display，the front is equipped with translucent or light guide panel.

DLP in a practical application,will have a reflective effect.　

LED because it is spontaneous light unit, and dark matte black panel、black led lamp surface, so the color expression of any angle can be maintained intact.

3. view angle compare

4. Display effect compare

5. contrast ratio compare

LED use black led lamp, the screen surface is absorption type structure. almost no straight line reflected light, So LED screen contrast ratio as high as 4000:1, makes the LED display screen more sharp and clear.

Most DLP projector contrast ratio can be 600:1 to 800:1, low price also can be 450：1。LCD projector contrast ratio is about 400:1，and low price only 250：1.

DLP video wall

DLP on the environment requirements are very high, such as temperature, humidity, dust, light, etc., especially the screen is the most vulnerable, scratch a thin line can not be erased and repaired, there is more cumbersome is not a period of time it will re-school it, otherwise the image will automatically offset. DLP’s actual contrast is very low, reflected in the dark scene expressive defects, that is, many images of dark scenes are not clear, this phenomenon is very obvious. Such as the notebook can see the dark scene, in the DLP screen on the black, can not distinguish, so when used in monitoring images, the image quality will be significantly reduced. DLP projector weakness only one, that is, “rainbow effect”, the specific performance is simply separated from the color of the red, green and blue three monochrome, looks like rainbow rain.

LCD video wall

The obvious disadvantage of LCD projector is that the black level is poor and the contrast is not very high.The black color of the LCD projector always looks gray, and the shaded part is dark and without details.This is very unsuit for play video, which is not very good for the movie, but it is not big difference with DLP projector when play words.The second drawback is that the effect of LCD projector is display a pixel structure, and the viewer appears to be viewing the image through a lattice. The SVGA (800 x 600) format of the LCD projector, regardless of the size of the screen image, can be seen clearly in the pixel grid unless a higher-resolution product is used. LCD now began to use the micro lens array (MLA), can improve the transmission efficiency of XGA format of LCD panels, lattice diffusion of pixels, the subtle and not obvious pixel grid, and the sharpness of the images will not bring any influence.It can reduce the pixel structure of the LCD to almost the same as the DLP projectors, but still a bit of a gap.

HD LED advantage

1.More than 100,000 hours of life time 

3.Best color performance

2.Superior heat dissipation performance

4.Low maintenance cost 

1.More than10 0000 hours life time

2.Superior heat dissipation performance 

The radiating surface is integrated, aluminum plate structure，Whole body heat conduction heat dissipation, can be the best heat dissipation；

Flank profile heat dissipation: The heat in the box is scattered from the sides, then connect the panels, In the back shell on both sides of the formation of the upper and lower channels, the use of air pressure to form the upper and lower air circulation principle, fully heat dissipation.

3.Best color performance

The display principle of RGB spontaneous light retains the authenticity of the color, avoiding the color loss and deviation caused by the material and the light running path in the technology of backlighting and projection.

YWTLED All In One LED – TV is a spontaneous light unit, with dark matte black bottom panel, black light bead surface, so that the color performance of any visual angle can be maintained intact.

4.Easy maintenance

Low maintenance cost

LED standard unit，display panel is composed of smaller units; display pixels are composed of individual LED lamp.

If there is a necrotic point, replace it with a spare unit and repair an LED lamp；

If the panel appears unrecoverable, a small display panel can be replaced；

For example, a 32-inch display area is only 4% of the traditional panel.

The current mainstream is a 46-inch, 55-inch, and 60-inch splice unit, with a lower proportional cost.

LED no difference after unit repair 

When replace single LED, can choose the LED lamp reserved in production. and the brightness single point correction can be carried out to keep it consistent；

When replace the unit module, the whole module and panels are used for the consistency correction, so that the color temperature and brightness are consistent with the current state of the project screen.

LCD video wall Big difference after unit repair

Replacement unit color and brightness are all new state, no attenuation, very uniform and bright；

And other original units, after long time use, brightness attenuation and screen and other factors, such as the volatilization of the light powder, the color, and brightness have declined sharply；

There are significant differences in overall visual effects。
