“Advanced Laser Phosphor Display” uses blue laser based on GaN to stimulate the moving fluorescent materials to produce one or more primary colors, applied to image display.It is the core technology for high brightness image display.
Recall that MiJia TV 150″ LED 3D Projector with an ultra-short focus has this technology.
In the field of film projection technology, there have been several rumors about ALPD ® technology. What is the truth in the end? Let’s try to debunk the most popular one.
Rumor 1: Lack of brightness
ALPD gives a brightness of 55,000 lumens, which is much higher than the 2000 lumens of the LED projector.
Currently, products built on this technology has passed tests by the National Institute of Film and Television of China. They are also recommended for commercial use.
Rumor 2: Color gamut issues
The ALPD technology does not correctly convey the colors Some people think that the projectors with the color gamut of ALPD technology do not reflect the colors that actually exist, but this is a deception. According to the research, the ALPD-laser color transfer corresponds to the DCI-P3 criterion set by Hollywood for the reproduction of digital films, and the ITU REC709 HDTV criterion. That is, the projector shows real images accurately, completely and with cinematic clarity. ALPD4.0 already covers the 90%~150% of gamut.
Rumor 3: Power Consumption
ALPD laser source uses GaN blue laser and fluorescent glowing materials high reliability, has the same cost structure as LED, and its cost is sharply reduced than the traditional laser. In the design of the remote rotating fluorescent structure, ALPD uses the least components to realize the fluorescent conversion and obtains the patent based on the technique itself. ALPD has lower cost comparing with the imitating ALPD laser products in the market.The ALPD laser fluorescence projector is cooled without the use of a compressor, which saves considerable energy costs. For example, if you use a device with an ALPD operating at a brightness of 20,000 lumens, then the energy consumption is 2500 watts. At the same time, the energy consumption in a laser projector on a xenon can be about 5000 W at a lower brightness.For RGB laser projection equipment, it requires cooling using a compressor, and the energy consumption is generally a xenon lamp device substantially close to about 5000W.
