What is the difference between the projector and LED screen?

1. Brief Introduction of Projectors

What is the projector? Users and the projector stand on the same side. The person can see pictures appear on the screen or flat surface through the projector reflected by the light. 

Pros: Ultra big screen size, flexible picture size, lower costs, simple structure, easy access to achieve high resolutions, multiple media input.

Cons: Caused by ambient brightness, its contrast is low, and uniformity is no good.


2. LED (Lighted Electronic Diode) screen

What is an LED? It utilizes the unidirectional conductivity of the diode. The electronic circuit is used to control its color and grayscale to realize graphic and video display.

Pros:

(1)High brightness with active luminous, adjustable to various surroundings, long life, individual pixel damage can be maintained without affecting the global.

(2)Bright colors, wide viewing angle, no image information loss of splicing screen, no size limited. 

(3)Real digital display device.

Cons: the cost is higher than projector in some way.

Features of creative LED screen:

(1) Small volume and long lifespan

Compared with other outdoor large display equipment, LED screen for outdoor advertising comes with smaller size and ten times longer life because there is a tiny chip encapsulated in epoxy resin, up to 50,000-100,000 hours, 10 times than traditional lights. 

(2) Lower power consumption

Low consumption saves a lot of energy. In the market, large lighting equipment is relying on the product consumption to improve brightness, but LED screen is not. Basically, the power consumption of LED screen remains 0.03-0.06W per single tube, transferring rate of 100% around. Even a single tube could save these energies, image that how many energies it could save with a lot of tubes. 

(3) High stability 

Normally lighting equipment will face the challenge of heat. LED display design comes with attributes of better heat dissipation due to its external interfaces and protective equipment. So, LED screen is improved to be a stable quality. 

(4) Color is more rich, close to nature color.

The LED light source can use the three primary color principles of red, green and blue. Under the control of computer technology, the three colors have 256 gray levels and can be mixed arbitrarily, so the LED screen can display any information from the computer to attract more attention. 

In short, highly efficient and environmental-friendly LED screens bring us much convenience. There’s still a long way to further study LED display technology so that we can benefit from it.
