What is macro rear projection

Macro Rear-Projection is a display imaging technology independently developed based on "Macro Rear-Projection (MRP)" technology.

rear projection

Each tiny pixel is composed of RGB-LED light source and spherical lens, which constitutes a tiny rear projection unit,

An independent dark room is formed to ensure the restoration of "black" in the picture;

◆Macro

The projection distance of each pixel is less than 3mm, ensuring uniform and soft light in the projected picture;

◆Continuous and seamless pixels

Each rear projection unit is closely connected to form a continuous pixel display screen without visual gaps.

Second, the advantages of macro rear projection

1. Safety eye protection, no light pollution

Testing agency: China National Institute of Standardization

Test method: select 100 people to watch the screen for 45 minutes before and after viewing, and use the instrument to measure

Test result: 1.95 as comfortable as reading a book

The World Health Organization (WHO) announced that more than 160,000 people around the world become blind every year due to blue light radiation.

What is blue light: Blue light is ubiquitous in life, and high-energy short-wave blue light ( between 440nm and 460nm) can cause damage to human eyes.

2. The pixel fill factor is approximately 100%

Macro rear projection is based on the performance of surface emission, so that the pixel filling factor is approximately 100%, similar to a projection screen.

3. The screen body is safe and explosion-proof

The surface of the macro rear projection is protected by a patented screen. If you tap, touch, or hit a basketball, the screen will not be damaged as long as it is not malicious.

4. Low failure rate, easy maintenance, no consumables

The macro rear projection solves the problems of traditional LED display screens: one is afraid of water, the other is afraid of dust, and the third is afraid of bumping. It has a lower failure rate than LED displays and can be wiped with a wet cloth. Wiping and other issues make the screen safer and easier to clean; the service life is as long as 100,000 hours, durable and stable, without consumables (mercury lamp, xenon lamp, laser), and the cost of replacing consumables is eliminated.

5. Not affected by ambient light, no moiré

With a brightness of 300cd/㎡, it will not be disturbed by indoor ambient light, and there is no need to turn off the lights and draw the curtains during meetings; the macro rear projection can remove more than 80% of moiré patterns, making the shooting picture cleaner.

6. Realistic colors and high contrast

The color of traditional LED is too bright and unreal; the brightness is too high, and it is uncomfortable to watch for a long time

The color reproduction of the macro rear projection is real and natural, and the expression is rich; the brightness is soft and not dazzling, and the eyes will not be tired after watching for a long time.

7. Ultra-thin, no noise, low power consumption, flexible installation

The thickness of the screen body is less than 60mm, which saves the installation space on site to the greatest extent; the flexible and changeable installation methods support vertical, hoisting and wall-mounted installations.

Fanless design, running sound 0db, relying on its own aluminum structure to dissipate heat from the screen and give you a quiet environment.

The power consumption is one-fifth of the small LED pitch of the same area, and the average power consumption is only 80-100W. It can be directly powered by 220v without changing the power supply.

Using its own super power processing technology, the screen runs for 3 hours, and the temperature of the screen will not exceed 3 degrees Celsius.

A single screen is larger than 100 inches, which can meet the viewing needs of multiple people at the same time. There is no optical seam in the picture, such as a whole picture, without affecting the visual effect.

3. Application of macro rear projection display products

Command and dispatch center, conference room, lecture hall, front desk background wall, etc.
