Every technological progress and breakthrough will fundamentally change the competitive landscape of an industry. This is also an excellent time for the latecomers to come, it depends on who can seize this opportunity.
The DLP video wall market has always been in a relatively stable competitive landscape. One of the most important reasons is that the product technology has not changed much. This situation began to break in 2010, because LED light source technology replaced UHP light source, and gradually became the mainstream technology in the industry. In this replacement process, some manufacturers quickly followed up and invested heavily in the research and development of new light sources and products, quickly seized the opportunities and established a competitive advantage. On the contrary, some manufacturers will adopt a wait-and-see attitude toward new technologies, and follow-up will be slower. As a result, they lose their opportunities. When new technologies and new products strongly impact the market, they are in a passive situation. As a result, the market competition pattern has also undergone tremendous changes. In this revolution in the replacement of UHP light sources by LED light sources, the most representative ones are the difference between Zhongda and Weichuang. In the same year (2009), DLP sales reached more than 2 billion, and Wei Chuang sold about 500 million, which is less than 300 million. However, in 2012, Zhongda DLP sold less than 300 million, but Wei Chuang It is already close to 11 billion (only DLP). Such an outcome is quite related to the switching speed of the two on the LED light source product and the promotion investment. Today, Weichuang basically no longer sells UHP light source products. On the contrary, UHP light source products still account for a considerable share of Zhongda's sales.
Now, new technological changes have come to us. Since the laser light source products debuted at Infocomm2012, in just one year, the sales of laser light source rear-projection movements have reached nearly 1,000 units. In the front-projection market, laser light source projector products are more and more popular, and many heavyweight manufacturers including Mitsubishi and LG continue to introduce laser light source products. In the face of the new laser light source technology, we can't help but ask, can laser light source really replace LED light source? Will it really become the mainstream technology of the future?
Let's compare the advantages and disadvantages of the laser source and the LED source. The answer will naturally be revealed.
First of all, from the perspective of brightness. The current LED light source still has the dilemma that it is difficult to increase the brightness. Even with a 3*6 LED light source chip, the brightness is only 1100 ANSI lumens. To continue to increase brightness, either use more sets of light source chips; or use more powerful chips. However, no matter what kind of solution, it will undoubtedly increase the probability of failure of the light source, or increase the difficulty of heat dissipation of the movement, and at the same time increase the power consumption of the movement. On the contrary, for laser sources, achieving high brightness can be said to be easy. At present, the laser light source can achieve a brightness of up to 30,000 ANSI. Taking the laser light source movement of Shenzhen Guangfeng Optoelectronics as an example, it has matured and mass produced a 4000 ANSI movement. Such brightness is still unimaginable for the LED light source.
Second, power consumption and energy efficiency ratio. The power consumption of the LED light source movement is greater than 300W, while the power consumption of the laser light source movement is only 130W. The energy efficiency ratio of the LED light source is only 3.5LM/W, while the energy efficiency ratio of the laser light source is as high as 12LM/W. If applied to multiple large splicing systems, the difference can be said to be one underground. Under the current global trend of focusing on environmental protection and energy conservation, it is self-evident that we can lead the future.
