When buying a projector, understanding parameter is important. Among them, brightness is a key indicator, a horizontal comparison of LED projector brightness of different brands, will find a difference: 3LED and 4LED. So, 3LED projector and 4LED projector, which is better?
What are the 3LED and 4LED of the projector?
1. LED refers to the light source type used by the projector as an LED lamp.
2. 3LED projector: Refers to the use of 3 lamp module projector, respectively red, green, blue three colors, the projector imaging picture color is completed by the three basic color light mixture, which depends on the RGB three-color LED light luminous intensity, but in fact, the triple light luminous efficiency is not the same, especially red light luminous efficiency is relatively low. Therefore, the overall brightness of the picture will be insufficient.
3. The 4LED projector is built on top of the 3LED with a Pump Blue LED, which is typically built in a four-channel architecture on high-quality models such as the Dangbei F3 projector. In this way, while increasing the cost, not only share the bulb attenuation pressure, but also improve the brightness.
