The long-awaited industrialization of ALPD5.0 technology has officially landed.

on September 7, the 10th anniversary new product launch conference of Dangbei was held in Hangzhou. the "Dangbei X5 Ultra 4K Super Full Color Laser Projection", a household intelligent projection product equipped with Guangfeng Technology (688007.SH)ALPD5.0 Super Full Color Laser Technology, was launched in the world. The successful launch of the product marks the perfect landing of ALPD5.0 super full-color laser technology in the field of projection, and it is also a milestone in the history of industry development.

R & D to overcome the industrialization problems of speckle and color edge

data show that the latest generation of ALPD5.0 technology of light peak technology was 2022 to TI DLP in November last year.®Officially released at the Technology Innovation Application Seminar. In less than a year since then, Guangfeng Technology has successively integrated R & D resources, overcome a large number of technical industrialization problems, and implemented higher standards for the production and manufacturing links. In September this year, it took the lead in joining forces in the field of home projection to achieve industrialization. application.

according to Chen zhi, general manager of the home core devices division of guangfeng science and technology, ALPD5.0 imaginatively combines six light sources with each other, learning from each other's strong points to create super full-color laser technology, which can visually realize the overall improvement of brightness, color, color gamut, color accuracy and comfort.

On the one hand, 5.0 technology continues the high-brightness core advantage that ALPD has always adhered to, and has been ahead of similar products in the market in terms of brightness indicators. On the other hand, while having unparalleled color performance, it also perfectly solves the problems of speckle and color edge for imaging.

"ALPD 5.0 is also the industry leader in solving the speckle and color edge problem, with technology and performance by a wide margin". Chen Zhi said.

In order to solve the physical phenomena of speckle and color edge of pure laser, Dr. Joseph Goodman of Harvard University once stated in the book "SPECKLE PHENOMENA IN OPTICS" (Speckle Theory and Application) that in order to reduce speckle contrast, The most effective means is to introduce incoherent light. Incoherent light is generally a continuous natural spectrum, such as sunlight or illumination light from a fluorescent lamp. Because the sun rarely appears or the table lamp looks speckle phenomenon.

In fact, it is impossible to directly introduce sunlight and fluorescent light into product design. It is necessary to rely on technological research and development to realize the simulation of sunlight, a natural, continuous and comfortable light as a light source. Increase the number of types of independent components in the light source, so as to effectively reduce the coherence of the light source, fundamentally solve the problem of speckle.

When there is a continuous spectrum in the light source, the light source transition is more natural and smooth. Finally, when imaging, the coincidence and smoothness of the edge display are greatly enhanced. Therefore, the problem of color edge is also solved.

So, the 5.0 success of ALPD lies in the creation of bionic natural light in the light source. In addition to the LED, it also completely retains the color advantage brought by the wavelength accuracy of the pure laser. Its display effect is better than that of pure LED or pure laser display products. This light is characterized by a spectrum of continuous, natural, comfortable, incoherent light.

Color index: accurate presentation of each color

As important as the distortion of image information caused by speckle and color edges is the over-rendering of the image. If the picture seen on the display device is too different from the real world, whether it is excessive rendering or distortion display caused by speckle and color edge, the viewer will unconsciously consume excessive brain energy and mental energy, thus causing a series of side effects such as visual fatigue.

ALPD 5.0 attaches great importance to the index of color accuracy. the color space of color accuracy is the three-dimensional model of LAB, which is more advanced and real than the traditional two-dimensional color space concept of color gamut coverage. In the research and development stage, the light peak uses hundreds of colors to calibrate the accuracy of the display of each color in the LAB three-dimensional color space, which can be said to achieve the accurate presentation of each color.

"only accurate color standard is not enough, and the most suitable light source must be dynamically adjusted according to the image content to present it. only in this way can the original image content be accurately restored. it is just like a person's clothes must fit properly." Chen Zhi, for example.

to put it simply, ALPD5.0 in the future has not only the high brightness of laser light source, but also the good color of LED light source and the wide color gamut of full-color laser, which makes the color details and texture of the picture more exquisite and the color restoration more real.

From "bright light" to "smart light"

American futurist Alvin Toffler pointed out in the third wave that human social and economic civilization has experienced agricultural economy, industrial economy and service economy, and the next stage is experience economy.

Specifically, people are more and more willing to pay for good feelings, and experiential consumption continues to expand and penetrate into all areas of life. Shaping new consumer values and delivering them to users has become the key point of competition and core competitiveness in various industries in the future.

the industrialization of ALPD5.0 for the first time put forward the concept from "bright light source" to "intelligent light source", realizing the modular and programmable multi-modal design of one machine with multiple functions. it is expected to introduce more algorithms in the future to meet different consumers and application scenarios, and truly enjoy several times the happiness of a product.

Chen zhi believes that ALPD5.0 is not only a simple highlight light source, but also a convertible magic cube AI platform. it has modular hardware design and programmable software platform. it can present various specifications and modes through different software and hardware configurations to meet the viewing demands of different scenes and consumers. When BeiX5 Ultra can switch light sources at will, users can enjoy a variety of light source technologies for a projection. Double the happiness, double the experience, and truly realize the "cinema-level enjoyment"!

"ALPD 5.0 is more like a key to explore the future world. Like the AI big model, the future will continue to evolve and transform, with stars on the top and the moon on the bottom, and you can enter the room". For the future development of ALPD5.0, Chen Zhi is full of confidence.

Guangfeng Technology was established in 2006. In the first 10 years of the company's establishment, it has been focusing on the research and development of core technologies and underlying technical architecture. Always adhere to the core technology core devices combined with multi-scenario application development ideas, and constantly accumulate and temper ALPD technology, to create a ubiquitous ALPD laser technology scene. At present, ALPD technology has been widely used in cinema, home/personal, automotive, engineering, education and AR fields.

when Bei X5 Ultra 4K Super Panchromatic Laser Projection "was released worldwide, it was also the first" technology ice-breaking "of ALPD5.0". As a leading enterprise in the laser display industry, Guangfeng Technology has always adhered to the concept of open cooperation and win-win, built a laser display ecosystem, and provided one-stop service for partners. At the same time, we continue to export new technologies and products for the industry, and work with peers and partners to promote the industrialization of laser display and jointly create a better vision.
