LED light source as a hot new technology in 2009, and its long life is expected to replace the traditional projection light source, so by the industry and consumers of great concern. Over the years, manufacturers continue to develop lamp-free LED display technology, and continue to improve LED brightness is expected to gradually replace the lamp in the coming years.
LED projection technologies, has opened a new era for the development of the projector. Compared to the traditional projector, projector using LED light source does not need the biggest advantage is that replacement bulbs.
At present the traditional LCD, DLP projector lamp life is about 1000-3000 hours, while the LED projector lamp life is even longer hours in the 10000-20000, the user fully without fear of depletion of the projector lamp.
1, LED light source of the micro-projector market
Personal mobile market is undoubtedly one of the most moving play mini-projector displays the value of new areas of the world's billions of mobile phones, PMP, digital cameras and other mobile devices, these devices not only affect the small size of the screen the user's visual experience, can not be achieved in these devices to share content, mini projectors will no doubt help these mobile devices can be large-screen display of the dream, so as to enhance the user's visual experience, to achieve more than in the content sharing.
The concept of self-produced pocket-sized projector since the vendors are eyeing this potential market, constantly on the portability of their products to upgrade. The wake of this development, micro-projection is also gradually expand the scope of application, in the business, home entertainment, tourism and other applications can be applied to these micro-industry products.
The application of LED light source was small projector body opened up a new road, due to small size, LED light, ideal for developing a more compact projector parts, making the products more portable and projector, which is the basic characteristics of pocket projector is entirely consistent.
Since last year, emerging market with DLP micro-micro-chip and LED light source projector, ultra-small body and long life, not only very convenient to carry, and the use of significantly reducing the user cost.
2, LED light source of the home projector market
In new technologies, new sources of development is still a hot market, LED light source is also further increase the brightness, while ultra-portable projector LED light source, while the small size, brightness, there is a degree of breakthrough, becoming the most concerned about individual users products.
In the home theater market, Vivitek pioneered in the early 08's first new high-definition LED home theater projector H9080FD, chipset and it uses PhlatLightPT120LED OSRAM REPCURF 9030A drive components DLP projector instead of the traditional color wheel and bulb in the . In the absence of the high heat lamp problems, it can be the same as the operation of an ordinary household electrical appliances which means that the customs, without preheating and cooling, the service life of up to 10 years.
LED light source for various manufacturers have used home projector market with confidence. LED light source of low cost, wide color gamut, low power consumption, it is the most attractive home where the projector. In addition, the need to replace light bulbs, can be the same as long as the TV used to make that the best alternative to large-screen television display device.
Meanwhile, LED light in color on the projector is also unique advantages compared with traditional light sources 80% of the NTSC color gamut about using three-color LED light source can reach up to 120% of the NTSC color gamut, can show a more extensive color screen, whether it is home theater, or business education, will have even better performance.
3, LED light source DLP Video Wall market
LED light source DLP Video Wall industries will change, making the rear projection liquid crystal display wall mosaic wall facing the challenge to meet, and continue to maintain market leadership mosaic wall, we agreed that the LED lighting system will be the 24 / 7 control room rear projection display system future trends, the technology will soon replace the traditional mercury arc lamp-based systems.
Although the LED light source itself is more expensive than mercury, but the whole system simpler light path to reduce the color wheel, so the cost of the entire mosaic wall system will not increase too much. As long service life and stability, and no ongoing maintenance, so the system will greatly reduce the use of cost, based on both cost and performance, LED light sources will soon replace the traditional mercury lamp system.
Recently, the new Mitsubishi Electric browse the Kyoto conference, see the DLP rear projection Mitsubishi's new monitors, through a set of 6 sets, 67PE-type LED light source DLP rear projection display, splicing out the side of the long 4893CM, non-wide 2042.6CM joint monitoring display wall, single screen resolution up to 1400x1050, the screen pixel density as high as 190 million pixels / square meter, while a new generation of LED backlighting will not only improve the color performance of displays, but will also improve the lifetime of the light-emitting unprecedented 60,000 hours, significantly reducing the cost of post-maintenance equipment supplies.
In addition, the new generation of DLP rear projection display device can also facilitate the maintenance of the system before the user can simply pull up the display panel, both observed the work of the internal components, users no longer need to disassemble the display, Dust protection maintenance work can be carried out, and even maintenance.
For new technology and new product development, continuous efforts are manufacturers pace, they will be continuous product improvement, continuous improvement, set in a variety of advantages, in order to highlight the product's core competitiveness, the challenges of different competitors, and occupy the market stable market share.
Recently, LED light source in the market's performance can be described as hot, inside and outside the industry seems to have the future development trend of LED light sources, to observe from the current market, LED lighting market in the micro-projector, home projector market, and rear projection display wall with great development prospects, a single spark is a prairie fire.
