Many projectors may see ALPD in some detailed pages of trendy projectors. But what’s ALPD?


ALPD is the acronym for Advanced Laser Phosphor Display, which is a kind of laser display technology widely used in laser projectors. It is also called fluorescent laser technology, used for image display based on laser-excited fluorescent materials and mixed multi-color laser lines.

ALPD 1.0

Working Principle and Development

This leading technology was developed by Appotronics in 2007. This technology has been updated from ALPD 1.0 to ALPD 4.0, which not only brings high brightness, good color reproduction, and no speckle advantages but also improves the height of technology and industry. ALPD 4.0 is 30% more powerful than ALPD 3.0.

ALPD 4.0

This technology uses laser and rare earth luminescent materials to support the color gamut coverage of laser projectors. Theoretically, its color gamut coverage can be as high as 90% of the human eye.

Many projector suppliers have applied this technology in their latest products.  For example, VAVA Chroma, and Dangbei X3.

Advantages of ALPD

High light efficiency

It is good for environmental protection and energy-saving.

High Brightness

High light efficiency determines high brightness. With ALPD technology, the brightness is up to 60, 000lm, maintaining a leading position in the world.

Wide color gamut

Phosphor plus laser, the color performance reaches DCI cinema level standard, and the maximum color gamut reaches 98.5% of Rec.2020.

High light utilization

High light utilization, high contrast 2500: 1, reaching cinema standards.


ALPD technology has overcome the most fundamental technical difficulties of laser display in terms of cost, efficiency, performance, and reliability.
