Appotronics –  Inventor of ALPD laser Display Technology 

What is ALPD®?

ALPD® (Advanced Laser Phosphor Display) is a semiconductor laser light source developed by Appotronics in 2007. It combines laser-excited phosphor with mixed color lasers to produce bright, efficient, and speckle-free light for displays and projectors.

Advantages of ALPD® Technology

High light efficiency

Environmental protection and energy saving

The light efficiency of ALPD ® projectors is much higher than that of other light sources.

High brightness

Powered by ALPD® technology, high light efficiency delivers Up to 60,000 lumens brightness—securing global leadership in laser display brightness performance.

Wide color gamut

The color performance meets DCI cinema-grade standards, with a maximum color gamut reaching 120% of Rec.2020.

High contrast 

Products using ALPD ® 4.0 can achieve a contrast ratio of 2500:1, far exceeding the cinema standard.

Continuous innovation of ALPD Technology

Dedicating over a decade to technological research, Appotronics has evolved from ALPD®1.0 to ALPD®5.0. This journey has delivered not only advantages like high brightness, vibrant colors, and speckle-free performance, but also elevated the standards of both technology and industry. It has gradually built a comprehensive technological system and continues to innovate.
