When buying a projector, understanding the parameters is an important part. Among them, brightness is a key indicator. When comparing the brightness of LED projectors of different brands, one difference will be found: 3LED and 4LED. So, what does the 3LED and 4LED of the projector mean and which of the two is better?
What is the meaning of 3LED and 4LED of the projector?
1. LED refers to the type of light source used by the projector is LED light.
2. 3LED projector: refers to the projector using 3 lamp modules, which are red, green, and blue. The image colors of the projector are all mixed by the three primary colors, which depends on the RGB three colors. The luminous intensity of LED lights, but in fact the luminous efficiency of these triple lights is different, especially the light efficiency of red light is relatively low, so it will cause the overall brightness of the picture to be insufficient.
3. 4LED projector adds a set of Pump Blue LEDs on the basis of 3LEDs. Generally, a four-channel architecture is used in high-quality models, such as Dangbei F3. In this way, while increasing the cost, it not only shares the bulb attenuation pressure, but also improves the brightness.
Which of the 3LED and 4LED of the projector is better?
The emergence of 4LED projectors is naturally a complement to the previous generation of RGB three-channel projectors. Projector manufacturers saw the shortcomings of 3LED projectors and made improvements. With the addition of Pump Blue LED 4LED projector, the volume of the body will increase (because the heat dissipation problem needs to be considered), and the brightness will be significantly improved. For example, the brightness of the Dangbei F3 is nearly half that of the previous generation F1. Of course, the price will rise and the life of the light source will also be extended.
In summary, the above is the description of 3LED and 4LED. Friends who want to buy smart projectors in the future can focus on this information and details. Of course, choose the 4LED projector with better color performance among the projectors of the same price.
