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.
