LED light source into a "rescue" DLP video wall unit hero

As the competition on the big screen becomes more and more fierce, the desire of new manufacturers for new products and new technologies has become stronger and stronger. DLP splicing with LED light source is now a high-tech display for large-screen display. Therefore, LED light source DLP splicing products have always been one of the key innovation industries in the industry. At present, the use of LED light source technology can be said to fundamentally change the practical performance of DLP splicing products. Here, we will use the LED light source DLP splicing unit series products launched by VATION to deeply understand the LED light source DLP splicing unit series. What are the advantages?

LED light source into a "rescue" DLP video wall unit hero

The emergence of ED light source products is of great significance for DLP splicing wall products. In recent years, the large-screen splicing display market has shown a state of three-legged. Among them, the market share of LCD splicing wall is close to 25%, PDP plasma splicing wall is about 4%, DLP rear projection splicing still maintains an absolute market share advantage of 68% (other splicing technology occupies 3% share), but this Does not indicate that the DLP splicing technology market throne does not face the risk of being replaced.

In fact, compared with DLP splicing walls, LCD and plasma splicing undoubtedly have an absolute competitive advantage in terms of product volume, maintenance, and especially lamp replacement. In recent years, the technology of LCD splicing has been advancing rapidly. With the emergence of more advanced products in the future, the seams will inevitably become smaller. The technical staff of the industry believes that the seam of the LCD splicing is also expected to be controlled to about 2 mm. If this is achieved, the competitive advantage of the DLP rear-projection splicing product will inevitably become obvious.

Among the three major display wall technologies, the weakness of DLP splicing technology in overall cost, as well as the overall cost of ownership and maintenance cost, are caused by the traditional mercury lamp source. Due to the use of mercury light source, the contrast and color performance are greatly limited, and the life of the bulb is not long. It needs to be replaced continuously. The color wheel used with the bulb should be frequently maintained. Due to the high frequency of maintenance, the optical path part cannot be completely closed. Design, dustproof and other properties have been affected, further increasing the maintenance strength. If you replace it with an LED light source, the above problems can be solved.

The application of LED light source makes the advantages of DLP more obvious

LED technology is one of the greatest inventions in the history of human light sources, comparable to the invention of incandescent lamps and lasers. LED technology has significant advantages in terms of display light as a projector, especially for DLP rear projection splicing wall unit products:

1. As we all know, the focus of most projector users is the life of the projector bulb, because the maintenance of the projector is on the projection bulb, and the birth of the LED and the application can completely solve this problem. Because LEDs can last up to 50,000-100,000 hours. This is the current DLP rear-projection light source with only 1000-6000 hours of unmatched light source life, almost 100% matching of light source products and optical machine life, equipment maintenance cycle is greatly extended, long-life LED light source also makes DLP video wall The frequency of maintenance is greatly reduced. The annual maintenance quantity can be reduced by at least 50%. This will also serve as an important “saving money” node and become one of the important added value for customers to purchase LED light source products. In addition, as an efficient light source product, LEDs will also bring higher luminous efficiency and higher light utilization efficiency, thus reflecting another part of the "low cost" feature of saving electricity.

2. With the progress of society, almost all urban people are paying attention to low-carbon environmental issues. The LED light source seems to be synonymous with low-carbon environmental protection today, because LED has neither dangerous rays nor toxic substances such as mercury; at the same time, LED light source has higher luminous efficiency and the same brightness can save more energy.

3. The LED light source is a digital light source, and the digital 01 code of the control signal can be directly loaded onto the light source chip after power amplification, and does not require excessive control flow, and the brightness adjustment range of the illumination effect is larger, and the color control is precise. Higher degrees and contrast can also achieve better display and test values. With full digital control, white balance adjustment is also easier, and color temperature control is simpler without affecting brightness and contrast.

4, LED is a kind of planar light source, the most basic light-emitting unit is a square package of 3~5mm side length, it is easy to combine together to become a surface light source with a certain area, with good brightness uniformity. This is extremely suitable for display technology to produce high quality and uniform picture effects.

As a well-known and market-leading brand in the domestic DLP rear projection large screen display industry, VATION has always been committed to promoting the development of the national independent DLP display industry. It has achieved leading technological breakthroughs at home and abroad in key technical fields such as product energy-saving technology, reliability optoelectronic design technology and integrated system supporting technology. Recently, VATION Juyang has launched a full range of LED light source VCVS-X series DLP splicing unit products from 50 to 84 inches. This is also the first time in the world that LED light sources are used in DLP rear projection display technology.

The DLP display unit of the new LED light source introduced by VATION adopts a new generation of LED light source. The energy conversion efficiency of the light source is high, and there is no environmental pollution problem of the ultra-high pressure mercury bulb. Therefore, the rear projection of the giant ocean light source is more than that of the ordinary light source. Environmental protection; In addition, the LED light source has a long life and long life - up to 60,000 hours. With the superior dustproof, shockproof and anti-aging properties of the giant display unit, the display unit truly has a long maintenance-free use period. The field contributes to the realization of green, low-carbon life and sustainable development, which is significantly superior to traditional mercury lamp products in terms of stability, display effect and cost of use.

In addition, VATION giant's original subtle color adjustment technology can independently adjust the seven primary colors of R, G, B, C, M, Y, and W, and simulate various complex mixed colors and transition color display modes. Joint adjustment of multi-primary mix and match. It greatly enriches the color adjustment method, making the color adjustment work infinitely refined, and the series has ultra-wide color gamut space (100% EBU) and excellent color and brightness stability, which can perfectly represent the true color of nature.
