DHN laser projector

The answer is yes, because compared to traditional projection technology, laser multimedia projectors has much more advantages. For example, laser multimedia projectors use a laser with a wider gamut of customizable wavelength hyperspectral brightness as a projection light source, it can achieve richer color gamut coverage, higher saturation, better color expression and better color reduction ability. At the same time, based on the three colors of red, green and blue, the laser beam is respectively extended to homogenize the field and eliminate the coherence, and then it is shot onto the light valve. The point light source becomes a surface light source, its negative impact on human eyes is minimized. Besides, from the popularity of laser multimedia projectors, it is a good thing for laser multimedia projectors manufacturers to join the competition. On the one hand, with the development of technology, product quality will be better and better, on the other hand, it will also bring t...

After the upgrade of a laser light source for projectors, more brands have entered this market, and many original brands have begun to lay out new markets in the era of laser light source. For example, the original engineering projector market is a high-end market, involving the market brand is not many. But now almost all the projector brands have introduced laser engineering projectors. So is the quality of all brands of products the same after the laser source? What is a good HD laser projector? It seems difficult to answer this question. The quality of products of different brands is definitely different. So how can we determine which products are better? Unfortunately, there is still a lack of standards in the HD laser projector industry. In fact, the HD laser projector is not just a laser. A projector with a laser doesn't mean it's a good projector. There are many kinds of laser sources, including monochrome laser, bichrome laser, and trichrome laser. Projector tec...

Short or ultra short throw projector beyond the confines of space sharply, it can better display its advantage than long or medium short throw projector, so it has developed fast in various field, especially in education. What is unique about short or ultra short throw projector when compared to ordinary throw projector. 1. High flexibility, which is suitable for small space Projector can be installed closer to image, so it can be applied with panorama in a smaller space with higher flexibility. 2. More activity space for users. Projector light takes up a small space distance because of low throw ratio, users can move in areas other than the projected light without being irritated by the light to the eyes, and the picture won't be damaged by the blocking of the figure. For users or lecturers, they all have bigger activity space. Besides, ultra short throw projector is the first choice for interactive handwriting and displaying, short or ultra short throw projector has got s...

With the promotion of projectors, more and more customers choose to use it to create immersive holographic experiences for their restaurants, hotels and pavilions. The imaging technology of projector is mainly divided into DLP and LCD. If you ask which is much better, we can only say that they each have their own strengths. If the life of the light source is the evaluation of the service life of the projector, then whether the dust prevention is good or not will affect the performance of the projector for a long time. If you compare the projector to a human being, a healthy person can live a long life, but if he suffers from a chronic disease, his body is damaged, his face is old, and his life expectancy is naturally reduced. Although compared with the LCD projector, the DLP projector does not have the problem of aging the LCD board at high temperature, and its life is relatively prolonged, it is still a project that needs to be fully packaged in order to improve the dustproof effe...

With the development and construction of the city, the elevator has become the most important means of transportation in city construction. Most elevators don't have 4G signal, and even mobile phone prompts are not in the service area. In such a closed environment, elevator passengers can't pay attention to mobile phones in the elevator. The obvious position of advertisements in the elevator will surely attract their attention to the past, which will bring a mandatory audience for advertisers to achieve the maximum marketing effect. In the strong demand for elevators, the future of digital elevator advertising is promising, and the elevator advertising market is also formed. When it comes to elevator ads, it can't help but remind people of the disorderly little paper ads in the elevator. It is such a small note that gave birth to elevator advertising so that the elevator has a new commercial value in the field of media. And then, in the era of the rapid development of ...

In recent years, China's projection market has been in a continuous downturn, overcapacity has brought serious inventory burden, low price as the support point of the sales thinking fatigue, frequent promotions caused by the phenomenon of not promoting sales throughout, so more and more manufacturers are constantly looking for new opportunities, in order to be able to make the projection industry vitality. However, the industry puts the new opportunity breakthrough point on the laser light source, laser projectors technology start from 2014, In the past three years, the number of participating manufacturers of laser projection doubled, the number of models on the market increased by dozens of times, and the product types completed the accurate coverage of all possible product lines, and the sales volume also achieved a huge breakthrough. According to the latest data of AVC, in the first half of 2016, the sales volume of China's laser projection market was close to 46,000 uni...

High-fidelity and high-definition projection effect is always the favorite of projection users. However, how to carefully debug and carefully operate the projection effect is difficult to achieve for ordinary projectors. After all, the performance of ordinary projectors and the technology they use are very limited. Therefore, in order to get the projection effect of the super-large picture and bright color, we still have to focus on those high-end projectors using new technology. At present, the high-end multimedia projectors in the market are mainly divided into LCD projectors and DLP projectors. An LCD projector is a mainstream product in the market. I am sure you will be familiar with all aspects of its knowledge. However, since DLP laser projector has only recently been launched, there may not be many users who know about DLP laser projector. The DLP laser projector is described below. DLP in laser projector is a new projection technology. It is the abbreviation of Digital Ligh...

The projector of the laser source can be said to be the most concerned projection source in recent years. Over the past two years, the laser source has gradually moved from the professional field to the field of daily life. It has great potential in business, education, engineering, household, and other fields. Advantages of Laser Multimedia Projector: 1. Stable performance The laser is a cold light source, the temperature of the machine will be greatly reduced, the burning degree of the display chip will be greatly reduced, and can maintain excellent color for a long time. The laser machine can switch on and off instantaneously without preheating and heat dissipation and the brightness can reach 100%. 2. High clarity under the same lumen, low attenuation of brightness in long-term use The brightness of the laser projector decreases slowly during long-term use, and its service life can reach more than 20,000 hours. 3. The total cost is lower than that of an ordinary bulb machine. ...
