What Should be Pay Attention to When Choosing the Projector for Home Theatre? In recent years, home projectors have been used more and more widely in home theaters. One of the main reasons is that the projector can project a larger image to give people a more shocking visual experience. As we all know, a laser TV of more than 100 inches is not cheap, but the projector can easily project a picture of more than 100 inches. You can even take it out to see a movie when picnic with your friends or your family. When people pursue a high quality of life at the same time, high quality of the home projector also came into being. But do you really know how to choose a projector for your home theatre? Then I will list some important points for reference when choosing a home projector. 1. Please consider what kind of effect you want. Sound and visual decide the effect of the home theatre. Of course, the withdrawal of visual effects is related to people's choice of display equipment. Disp...

The Secret Technique Of DLP Projector: Color Wheel Dustproof Technology

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...

Is Laser Projector Better?

Is Laser Projector Better? Is laser projector better? Before we get into that, let's figure out what a laser projector is and the development of the projector. So what is the laser projector? And what is the development history of the projector? laser projector Let's start with the development of projectors. The birth of the projector: In 1640, a Jesuit priest named Cheyser invented a slide projector called magic light, which used the principle of reflecting light from lenses and mirrors to reflect a series of pictures onto the wall. It was a great invention at that time. It was very popular. With the rapid development of industrial revolution, slide projector has entered the industrial age. The industrial production of slide projector began in 1845, and the light source was changed from candles at the beginning, to oil lamp, gas lamp, and finally to electric light source. In order to improve the quality and brightness of the picture, concave reflector is installed at t...

The Advantages of Laser Projector

Over 20,000 lumens, the mainstream of the market is RGB laser projection, mainly the digital film projector of Barco and SciDev. Under 4000 lumens, the market mainstream is hybrid LED/laser projection technology and older LPD technology, mainly 2000-3000 lumens Casio hybrid LED/laser projection or 2000 lumens BenQ laser projection. Of the 5,000-10,000 lumen projectors most needed in the engineering market, lasers are the most suitable technology for engineering projectors. The integrated design of light source and light machine achieves high brightness without color drift and speckle. This design includes efficient integrated optical design and super dust-proof design ensure that the impact of dust on brightness attenuation is reduced. Premier customization color control technology allows accurate color for more diverse industries and applications. Calibration and setting, and through intelligent design, users can use it very easily. The brightness attenuation of DHN projector is ve...

Classification, Characteristics And Application Analysis Of Immersive Interactive Projection

Classification, Characteristics And Application Analysis Of Immersive Interactive Projection Immersive interactive projection has attracted much attention in recent years and our company, DHN, is very sophisticated in this field. As a new way of projection, as a product of high-tech innovation, it surrounds the audience from all levels and can fully cover the perspective of the audience, to achieve an immersive sense of experience and it has been applied in more and more fields. 1. The principle of immersive interactive projection The principle of immersive projection is to use the projector to project the picture onto a large or multi-sided projection screen, and then with the help of multi-channel projection fusion technology to make the picture show a better effect. The system can provide a room-size four-sided (or six-sided) cube projection display space, combined with the sound system and action acquisition system to create an immersive three-dimensional audio-visual interactiv...

What is The Brightness of “The Light Source”?

What is The Brightness of “The Light Source”? As we all know, for the projector, brightness is an extremely important indicator. It is concern about the usage of the projectors. However, recently in the projection market, especially in the home theater market, the concept of light source brightness has appeared. But the questions is does the users really know the meaning of the light source brightness? Or the light source brightness will influence the choice of the users when they want to buy a projector for home theater? The concept of the projector's brightness refers to the brightness when projected projector brightest white screen brightness in the normalized over the projection screen in the ideal environment. Among them, the meaning of the ideal environment is "the light transmission from the lens to the projection screen does not cause any loss of brightness "; the meaning of "standardized ideal projection screen" is that the reflective of this curta...

DHN Laser Projector's Edge Blending Function and it's Application

DHN Laser Projector's Edge Blending Function and it's Application With the continuous progress of society and the rapid development of science and technology, the impression of super-large screens and ultra-high-definition screens continues to impact everyone's eyes, which giving people a complete and real visual enjoyment. So, people gradually realized that a single display device can no longer meet people's needs for some large-scale outdoor displays and some large-scale image simulation displays. At the same time, it also requires the innovation of our technology in display size, display resolution and display brightness. In this situation, the seamless edge blending skill came into being. It solves the problems of screen size, resolution, brightness limitation. Large Screen Projection The birth of the edge blending projector has made "seamless stitching" truly move to the "seamless" era. The edge blending technology uses pixel superimpositi...

The Difference Between Edge Blending Projection and Traditional Splicing Display

图片
What is Edge Blending Technology? Edge Blending technology is to overlap the images projected by a group of projectors, and use the fusion technology to make the brightness of the overlapping part consistent with the entire large screen, thereby displaying a brighter, super-large, high-resolution whole picture without gaps. The effect of the picture is like the picture quality projected by one projector. Large Screen Projection What is splicing display? Projection splicing: also called projection hard spelling, which means that two or more projectors project and splice a large picture at the same time, without using projection edge fusion, and let the pictures projected by each projector directly lean together. Projection Splicing Display The main differences between edge blending projection and traditional splicing display: 1. In the traditional splicing system, the entire large screen is a screen display body composed of multiple separate screens. Although the same material is...
