    Technical architecture

    Covers various regions such as China, the United States, Japan, South Korea, Taiwan, Europe, India, and Russia.

History of ALPD®technology


In 2007, it pioneered the subversive ALPD®laser display technology, and registered the ALPD®basic patent in the US and China Patent Office.
In 2011, ALPD®1.0 was successfully launched and applied to Laser DLP Video Wall
It is the first generation technology combining blue light and phosphor, with the simplest architecture
integrating phosphor and filter minimum devices.

History of ALPD® technology


developed in 2012, for Laser TV product development 
High brightness 
Visual safety design
Same light path, good uniformity

History of ALPD® technology


developed in 2015, mainly based on red and blue two-color laser + phosphor technology, developed for cinemas 
High brightness
DCI P3 color gamut
100% color brightness

History of ALPD® technology


developed in 2018, phosphor + tri-color laser solution for ultimate viewing effect  Larger color gamut (color gamut value reaches 98.5% of Rec.2020) 
Higher contrast (far beyond cinema standard 4000:1) 
Higher light efficiency (30% more efficient than ALPD® 3.0 generation products)


In 2007, APLD® technology was initiated in the world.

Advantages of ALPD® Technology

  • High light efficiency• Environment friendly and energy saving

    The overall light efficiency of the ALPD® digital projector is much higher than other light sources.

  • High brightness

    High light efficiency determines high brightness, with ALPD® technology, the brightness is up to 55,000lm, maintaining a leading position in the world

  • Wide color gamut

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

  • High contrast

    High light utilization, high contrast 4000: 1, reach and exceed cinema standards

  • High reliability

    Products using ALPD® laser display technology.Through aging test, dust proof test (verified to be IP5X dustproof rating),
    heat dissipation test, structural strength test, high temperature and high humidity and other experimental tests, it is proved to be a reliable laser technology

    The first ALPD® laser source theater was installed on June 28, 2014 in Shenzhen OCT Harbour Cinema, and it has been operating without problems.

  • High light efficiency• environmental protection and energy saving
  • High brightness
  • Wide color gamut
  • High contrast
  • High reliability
