Laser Projector Refit and original points

Aug 21, 2018

The projection market  entered the laser era, not only in the traditional business education  market, but also in the high-end digital projector market. Laser  light sources have become a trend in the digital cinema projection  industry due to their low cost, wide color gamut and high contrast. With  the increase in the demand for laser film projectors in the cinema,  laser projectors are expected to occupy more than 30% of the entire  projector market in about 30%. In 2017, the film screening industry has  fully entered the laser era.

From the  attitudes of NEC, Barco, Sony, Christie and other world's top digital  projector manufacturers, the market strategy center is placed on the  laser projector digital projector product layout. In  addition, the emergence of a number of emerging digital projector  brands in China has also chosen to betray laser technology in order to  obtain a "one cup" in the digital projector market.

However, behind the continuous red-hot laser digital projectors, there is indeed a “floating wind”. In  order to be able to grab and score the eyeballs, some brands even don’t  hesitate to make “retrofit” cards in laser projectors. They simply use  the so-called “upgraded” laser source for the original traditional light  source machine, which is known as a “laser”. The projector is up. Because  of the simple upgrade of the light source, it does not really form a  "laser projector system." Therefore, many "laser projectors" on the  market that are relatively cheaper are likely to be "retrofit machines."


What are the disadvantages of the “retrofit” version of the laser projector?

In terms of hardware structure, does the laser module match the xenon lamp? According  to NEC digital projector related personnel, some "retrofit laser  projectors" appear on the market. It is like replacing the fuel tank of a  normal fuel vehicle with a battery. Its cruising range, battery life  and handling performance can be combined with battery-based power. Is the Tesla of the car design comparable? The  heat-dissipating and dust-proof structure of the xenon lamp projector  is not designed according to the requirements of the laser light source,  and the high-precision temperature control and high dust-proof  performance required by the laser cannot be achieved, which may cause  display quality problems such as increased brightness attenuation and  screen color cast. What's more, in order to  improve the heat dissipation performance, an external liquid cooling  module is attached, which not only affects the appearance, but also is  difficult to carry out daily maintenance, and the heat dissipation  effect is also unsatisfactory.


In terms of system stability, "reconstructing a laser projector" may also cause problems with reduced image quality. Because  the design of the Xenon platform software is difficult to communicate  and coordinate with the modified laser light source in real sense, it is  impossible to achieve the original characteristics such as precise  color adjustment and overall efficient heat dissipation, resulting in a  decline in the quality of the projection.


As a leader in  laser projectors, NEC believes that laser projectors are aimed at the  high-end digital cinema market and are very demanding standards for  quality technology and services. If you just want  to seek low-cost and take the impulse to take the "retrofit" of the  laser projector, this is a short-sighted behavior, and it will also mess  up the "architecture system" that the digital projector industry always  pays attention to quality and technology. The development of the newly emerging laser projector is extremely unfavorable.

To this end, NEC is a firm opponent of the light source modification machine. NEC believes that only the perfect hardware structure with the perfect software system is the perfect laser printing product. As  a pioneer brand of laser projectors, NEC always adheres to the original  original laser projectors, realizing the advantages of long life, high  image quality, zero maintenance and low operating cost brought by laser,  and guarantees the quality of the show with its own practical actions  and corporate conscience.


Some industries said that in the next two years, the sales of laser projectors will exceed the traditional Xenon projectors. In the digital cinema machine market, who is most active and determined about laser display technology will take the initiative. At  present, NEC has built the most complete product line in the laser  projector market, including monochrome, two-color, and three-color  technologies, and also deep penetration in 4K technology. It can be said  that NEC has the most complete brand in laser projector layout. This will undoubtedly occupy a favorable position in the future laser projector competition.
