Over 20,000 lumens, the mainstream of the market is RGB laser projection, mainly the digital film projector of Barco and SciDev. Under 4000 lumens, the market mainstream is hybrid LED/laser projection technology and older LPD technology, mainly 2000-3000 lumens Casio hybrid LED/laser projection or 2000 lumens BenQ laser projection. Of the 5,000-10,000 lumen projectors most needed in the engineering market, lasers are the most suitable technology for engineering projectors. The integrated design of light source and light machine achieves high brightness without color drift and speckle. This design includes efficient integrated optical design and super dust-proof design ensure that the impact of dust on brightness attenuation is reduced. Premier customization color control technology allows accurate color for more diverse industries and applications.
Calibration and setting, and through intelligent design, users can use it very easily.
The brightness attenuation of DHN projector is very slow. The lamp life of traditional projector is very short, only 2000 hours. In practical use, the DHN laser projection provides much higher visual brightness than the traditional bulb projection, which decreases to 50% of the initial value in 1000 hours, and the brightness quickly decreases to less than 70% of the nominal value. DHN laser engineering projector has high visual brightness. DHN laser projection
can accurately reproduce the gamut of Rec. 709 and display rich colors. This feature makes him not only suitable for meeting rooms, but also for stage performances, museum exhibitions and virtual simulation. Traditional bulb projectors produce only white light. The maximum light flux that each bulb can output is fixed. White light passes through the color wheel and filters out three basic colors: red, green and blue. The more light filtered, the bigger the gamut and the lower the brightness. The bulb projector pursues higher brightness by sacrificing part of the gamut.
Visually, the red orange, green yellow and blue of the bulb projector are somewhat green. The color gamut of traditional projectors is mostly smaller than that defined by Rec. 709.
DHN laser projector support supports a variety of 3D formats, including DLP Link, infrared, passive and so on. For example, through DLP Link, it can directly realize the 3D active stereo projection display function without connecting the transmitter. Or through infrared transmitter to achieve active stereo projection display effect, dual passive stereo display effect is more outstanding.
AVANZA laser projection supports a variety of 3D formats, including DLP Link, infrared, passive and so on. For example, through DLP Link, it can directly realize the 3D active stereo projection display function without the transmitter. Or through infrared transmitter to achieve active stereo projection display effect, dual passive stereo display effect is more outstanding. The lifetime of DHN laser projection is over 20,000 hours, and it has stable brightness and color output. Most importantly, it is no longer necessary to constantly adjust the projector to ensure the effect of multi-projectors edge blending .
The life of the bulb used in the traditional projector refers to all the bulbs manufactured. After a period of work, 50% of the bulbs have some faults, such as flicker, unstable work, illumination and physical breakdown. This time is defined as the life of the bulb. The lifetime of the light source of a laser projector means that the brightness output of the projector decreases to 50% of the initial value. Different types of projectors have different definitions of the lifetime of the light source. The life of the bulb projector has the following curves, the horizontal direction is the life time, and the vertical direction is the failure rate. It can be seen that when the bulb works at full power, by 2000 hours, 50% of the number of failures have occurred, which is the source of 2000 hours of life.
For most customers, the actual brightness output of the projector is the most critical, so we also pay attention to the actual light bulb brightness attenuation curve. The light source of the traditional projector produces a large amount of ultraviolet and infrared light, which radiates as heat. Heat and invisible light radiation rapidly aging the internal parts of the projector, reducing the life and stability of the projector. In addition, a large part of the electricity is converted into invisible light, which is also a reason for the high power consumption of traditional projectors.
Technological innovation has been constantly changing industry rules, projection display industry is no exception. Laser projector technology
will bring unprecedented tremendous changes to the display industry. After this change, new industry layout will emerge, some familiar brands will disappear, and some emerging brands will be established.
