The digitization, network and multimedia interconnection of projection display technology have been realized. The core components of projection products include light source lighting system, color separation and color processing system, projection lens, image signal processing circuit, micro display device, etc. In terms of display effect, the current projection products can fully meet the needs of users.
DLP Projector uses the technology of Digital Light Processing. In layman terms, there is a chip called the DMD or the digital micro-mirror device which consists of more than two million tinier mirrors. These tiny mirrors can move towards or away from the light source, to direct the light towards an image. It also consists of a spinning color wheel that delivers color and projects it on the screen. The light source used is LED or lamp. DLP projectors with the LED technology is easier to handle because the lamp need not be replaced, saving both time and money.
This kind of projectors is mainly used in classrooms and schools and colleges. They are less expensive compared to the other technologies and are often used as home theater projectors.
A technical difference, a projector is called an LCD projector if it used the technology of liquid crystal display.
There are two types of LCD projectors. A 3-chip LCD projector as well as a single chip LCD projector.The LCD which contains three separate glass panels – one for red, green and blue components of the image that is being sent to the projector. As the light passes through the panel, individual pixels open and close to allow light to pass or close to block the light depending on the image.
The ideal projector choice is dependent on a few factors. Depending on your budget, whether you intend to use it as a home theater or office presentations, or will be used while traveling. Each of the technologies has strengths and weaknesses in different fields. You’d want to look into the projector that has the least disadvantages in the field you want to implement it in and opt for that one that both fits into your budget and outperforms the other in the specific area.
Getting conversant with the strengths and weaknesses is hence crucial to choose the right type for your use. We hope that you will make the right choice when presented with a DLP vs 3LCD scenario.
