On July 25, the press conference of Guangzhou Zhongjin · inask · Yingshi HLD new light source projector was held in the premier Hall of Guangzhou President Hotel. With the HLD new light source projection products, a discussion on the upstream and downstream of the industrial chain, including light source manufacturers, complete machine manufacturers and agents, is also launched here.

HLD light source attacks, laser to meet the hand?

At this stage to discuss a kind of projection light source, even if it is new, it certainly can't bypass the laser light source.

In fact, at the moment when laser light source is booming and its excellent performance has been widely praised, we are still curious about Philips' vigorous development of HLD light source and a group of small partners to follow "play with". Curiosity has three main points

First, is HLD really mature?

Although in the second half of last year, we learned about HLD light source information in the product promotion of some manufacturers, but it is undeniable that HLD is still a very new concept, and we have rarely seen relevant reports up to now. We can't help but ask, is HLD technology really mature?

First of all, we should be clear that HLD is not mysterious. It is actually a high brightness LED light source launched by Philips (at present, Philips has improved the luminous efficiency of green LED), so you can take it as the highlight or high-end version of Philips LED light source. As a global leader in general lighting, Philips has a profound technology accumulation from UHP to LED. As early as 2015, Philips announced to the outside world that its colorspark HLD led innovative technology was officially launched. This is the HLD light source we are talking about at the moment.

"It can be said that HLD is definitely at a time when the technology is mature and can be put into the market." Mr. Wang Zhijie, sales director of Philips Greater China and South Korea, solemnly pointed out that this year will be an extremely important year for HLD light source. HLD has developed into the second generation products now. Besides inheriting all the advantages of LED light source, it has also achieved 3000 ~ 6 brightness, 000 lumens, covering the most mainstream brightness segment of current projection applications and several of the largest application markets including education, home and so on. "The emergence of HLD light source provides a new choice for the market," he said

Second, HLD is superior to laser? What are the advantages of HLD?

After UHP bulb light source for projection, three kinds of solid-state light sources appeared in the market, namely: RGB, laser phosphor, laser + LED light source, to solve the user's pain points with a long life cycle, which was recognized and accepted by the market.

Since we want to talk about advantages, we should certainly attack its weaknesses. Compared with the laser display with the highest market share and the best comprehensive application, HLD has certain advantages in security, color and cost.

The first is security. If the safety of high-energy point light source is criticized intentionally or unintentionally in the market, then this situation does not exist in HLD technology. This is particularly important in the education and home markets, where safety requirements are prominent.

Color is also an advantage of HLD. According to the universal rec.709 standard gamut coverage, although the laser has been very excellent, HLD still leads a lot. In fact, there are some views on the market that the blue of the picture is not very pure for the home projector field which pursues the ultimate color. The pure laser light source is obviously not the best choice. HLD technology is naturally brought into view.

In terms of cost, according to Mr. Wang Zhijie, "led has occupied 50% of the global general lighting market, and this proportion will continue to expand. As far as the cost of LED light source is far better than that of other manufacturers in the upstream and downstream supply chain, "he said

In addition, due to the simplification of the optical path design of HLD technology, it is easier to realize the miniaturization of the equipment than the laser projector, and has advantages in reliability and maintainability.

Of course, it would be too arbitrary to say that HLD light source is superior to laser light source. Laser light source is only the brightness of tens of thousands of lumens, which is not expected by the current HLD technology, or even can never be surpassed.

Third, why should Philips and its partners develop HLD light sources?

Whether it is mature technology or high security, good color performance, cost advantages, it is obviously not enough to fully explain the reasons why all parties are optimistic about HLD technology.

The popularity of the event site exceeded our expectation. Why do you look forward to a new light source? This is also the problem we need to make clear that Philips is widely supported in HLD.

"Laser is very popular indeed, but also because of this very fierce, channel profit is pressed very low." Mr. Liu Yuan, sales director of weishijiajie business equipment business unit, said that "the emergence of HLD has given everyone an opportunity to differentiate competition and a new profit exploration point."

In my opinion, this may also add new story telling elements to the projection market, which has long been uninspired, and also serves as a stimulant in a certain sense.

Will HLD become the mainstream light source for digital projection?

"Stimulant" is certainly a mockery. In the face of the strength of laser light source, Philips, Jiajie and a number of small partners are certainly not playing fast in developing and promoting HLD.

According to Mr. Wang Zhijie, at present, the luminous efficiency of HLD light source will improve by 20% - 30% every half a year, nearly doubling from one year to one and a half years. Of course, this improvement will not be endless, but it obviously gives us a strong confidence to withstand the pressure of laser and develop HLD technology.

In addition, we can also imagine that from the most important core components of the projector system, the combination of HLD (light source) and color focused 3lcd (light valve) will certainly complement each other, which will certainly make a number of manufacturers in the field of 3lcd restless, and will also cause trouble to manufacturers who have launched laser light source 3lcd in the market.

It has the advantages of safety, color and cost; it has a long service life comparable to that of laser light source, which solves the biggest pain point of users; it stimulates new promotion highlights and solves the urgent need of channels It can be imagined that HLD technology will make great progress on the road of becoming the mainstream light source of digital projection.
