The principles and advantages of single DLP chip projection

The so-called single DLP chip projection refers to the product that adopts a single DLP DMD chip solution, which is also the core component of the DLP projector. However, the DLP chip is not an ordinary semiconductor chip. It also integrates a physical matrix structure composed of a large number of reflective lenses. The area of ​​each lens is only micrometers, corresponding to one pixel of the picture. For example, on a DMD chip with a resolution of 1920×1200, the number of small lenses is as high as 2,304,000.

However, these small lenses are not static. They are "suspended" and fixed by a special hinge mechanism and can be deflected at a certain angle. The image signal input into the projector will first be converted into a digital signal and transmitted to the DMD chip. The CMOS at the bottom of the DMD chip will control the duty cycle of the deflection of each small lens according to the brightness of the image. These small lenses will deflect and vibrate at high speed, so that the DMD chip can display the entire image continuously. The light source of the projector will be reflected from the DMD chip to present an image, which will then be projected onto the screen through the lens.

The DLP chip works on the principle of reflection, but the reflection of a single DLP chip solution is monochrome. Therefore, in order to display color images, a single DLP chip projector is equipped with a color wheel, which is actually a disk that allows light to pass through and then output. The laser color formation principle (as shown in the schematic diagram of the color operation principle (Green) example) is synchronized with the display refresh rate, so that the color rotation can be completed in a very short time. Under the effect of visual persistence, DLP projection finally completes the color mixing effect of the picture.

In 1987, the first DMD chip was born in the laboratory, and 11 years later, the first DLP projector came out. After more than 20 years of development, DLP projection technology has become more mature. The images projected by DLP projectors have brighter colors and higher contrast, and the smaller pixel pitch makes the image display more detailed. Therefore, projectors with a single DLP chip have gradually entered the mainstream market.

Why has single DLP chip projection become the mainstream in the market?

From the above content, we can know that the DLP projector adopts the reflective working principle. The gap between the reflective lenses on the DMD chip is small, and the light utilization rate can reach 20%-30%, while the light utilization rate of the transmissive LCD is less than 10%. Therefore, the optical path of a single DLP projector is simpler, and the components are small and light, which also provides unlimited possibilities for the "slimming down" of the projector.

Of course, there is also "involution" between DLP projectors. In addition to single DLP chips, there are also 3DLP chip products on the market, which are equipped with 3 DMD chips, and the light source is changed from monochrome to independent red, green and blue. Each DMD chip only reflects one color of light, and the color wheel component is removed. The structure of the projector with three DMD chips is relatively more complex, and the heat generated during operation is also greater. It requires a better cooling system, a larger size, and a higher manufacturing cost. It is usually used in some special professional fields and can only be installed in a fixed way.

Nowadays, projectors are increasingly used, but most users do not have a rich computer knowledge base, so there is an increasing demand to extend the life of the product and reduce the frequency and difficulty of maintenance. In traditional LCD projectors, the liquid crystal molecules in the core component LCD panel are easily decomposed in a high temperature environment, resulting in a serious decline in image quality. At the same time, the LCD panel needs flowing air to cool down when working, which is easy to accumulate dust, which not only affects the image quality, but also causes heat accumulation, further reducing the life of the projector.

Single DLP chip projectors have an "innate" advantage in this regard. Since the DMD chip, the core component of a single DLP projector, uses reflective technology, it absorbs less heat energy when working, and the semiconductor chip is more resistant to high temperatures, so the picture will not show obvious degradation after long-term use. At the same time, a single DLP projector can use a relatively closed optical path structure, and some of FLYIN's products can even be completely sealed, which fundamentally avoids dust deposition causing image quality degradation and heat accumulation, which also means that this type of projector can truly achieve "maintenance-free."

How to make cultural tourism "rejuvenate"?

During this year's May Day holiday, scenic spots across the country were once again crowded with people, and even Mount Everest was "jammed", which shows that the recovery momentum of the tourism industry is very rapid. The current cultural and tourism industry is undergoing changes, especially some scenic spots with ethnic customs and red history, which are actively creating diversified interactive cultural and tourism projects, empowering the integration of culture and tourism through scientific and technological forces such as laser projectors, and giving new vitality to scenic spots.

The cultural tourism market has always been the largest incremental market for laser engineering projectors and an important direction for the development of the projection industry. "Natural landscape + projection lighting art + cultural characteristics" has become the most common practice for modern scenic spots to increase traffic. Some cities have even introduced new imaging technologies to showcase urban culture and polish the city's new "business card". After nightfall, the wonderful images attract a large number of citizens to watch, becoming a beautiful landscape in the city.

However, for the cultural and tourism industry, the use and management of projectors can be said to be "extensive". Therefore, how to obtain the most stable user experience and meet the expected picture effects with the least manpower and financial investment has become the most basic demand of scenic spots. With its high efficiency, high cost performance, long life and maintenance-free characteristics, single DLP laser projector provides perfect picture performance and stable operation guarantee for large-scale stage performances, theme parks, urban culture, etc.

Safeguarding the cultural tourism market

Single DLP projection is more "out of the circle"

Compared with ordinary commercial use, the use of projection in the cultural and tourism industry can be described as "out of the circle". For example, to create a wider image, or even a 360° panorama, it is necessary to use the image stitching of the projector. In order to avoid the problem of inconsistent color and brightness between the various images, the seamless cooperation between the projectors has become an important factor in the perfect display of the picture. At the same time, since projectors in the cultural and tourism industry are often used outdoors, higher requirements are also placed on the brightness of the picture.

、

It can be said that cultural tourism has guided the development of the projection industry in a new direction, and at the same time has forced projection manufacturers to continuously upgrade their technology. Among them, FLYIN has launched a new single DLP force - the SNP-LU31K series, which is not only the industry-leading 30K+ lumen DLP chip projector, but also uses the most advanced software and hardware technology. For example, its camera sensing technology and geometric correction function can realize automatic picture calibration, and the splicing color calibration mode can measure the color of multiple projectors and establish accurate color performance, providing the best user experience for the cultural tourism industry.
