How to Choose an LCD Projector That Suits You

In today’s digital era, the rise of the projector industry has had a profound impact on the market. Projection technology is divided into LCD, DLP, and LCOS.  As a high-definition and high-color reproduction projection equipment, LCD is widely used in business demonstrations, education and training, home entertainment and other fields, becoming an indispensable part of modern life. This article will introduce some factors you need to consider when choosing an LCD projector.

Main Parameters



The first thing to consider is the resolution of the projector, which is the clarity of the projected image. Typically, high-resolution projectors produce clearer, more detailed images. The high-definition resolution of 1080P can already meet the needs of most users, but if you need higher image quality, you can choose a projector that supports 4K resolution.



The brightness of a projector is usually measured in lumens (ANSI lumens). The higher the brightness, the clearer the projected image will be in a brightly lit environment. Generally speaking, if you use a projector in a bright environment, such as during the day or in a room with lights, you need to choose a projector with higher brightness.


Contrast refers to the color difference between the projector’s display of black and white. Higher contrast can make images look more vivid and three-dimensional. Therefore, when choosing a projector, try to choose a product with a higher contrast ratio.

Projection distance and projection size

Projection distance and projection size

The projection distance and projection size of the projector are also factors to consider. Different projectors have different projection ranges and projection ratios. Choose the appropriate projector according to your projection needs and usage scenarios.

Functions and interfaces

In addition to basic projection functions, some projectors also have various additional functions, such as wireless connections, built-in speakers, 3D functions, etc. You can choose a projector with appropriate features based on your needs.

Brand and price/performance ratio

Finally, you can also consider the brand and price/performance ratio of the projector. Products from some well-known brands usually have better quality and service, but may also be priced higher. Therefore, you can choose products with higher price ratio according to your budget and needs.

Optical System

The optical system is the core component of the projector and directly affects the quality and performance of the projected image. Here are a few key factors to consider in optical system design when choosing a projector:

Optical component quality

The optical system of the projector includes various optical components, such as lenses, reflectors, lenses, etc. The quality of these optical components directly affects the clarity and color reproduction of the projected image, so it is necessary to choose optical components with reliable quality.

Light path design

Light path design affects the projection angle and projection distance of the projected image. Some projectors have adjustable optical system designs that can be adjusted according to different projection needs, improving the flexibility and applicability of projection.

Dust-proof design

For scenes that require stable projection for a long time, dust-proof design is an important consideration. Some projectors adopt a fully enclosed optical machine design, which can effectively prevent external dust and impurities from entering the optical system and maintain the clarity and stability of the projected image.


In the LCD projector industry, a variety of optical-mechanical technologies are used to achieve excellent projection effects. Among them, they mainly include transmissive optical machines, reflective optical machines, liquid-cooled optical machines and the latest fully enclosed optical machine technology in the industry.

Open optical machine

Advantages: The transmission optical machine has the characteristics of simple structure and low cost, is suitable for mass production, and has high imaging brightness.

Shortcomings: Easily affected by dust, the light path is easily contaminated, and requires frequent maintenance and cleaning.

Reflective light machine

Advantages: The optical path of the reflective optical machine is relatively complex, but it has the characteristics of strong dust resistance, high stability and high optical efficiency.

Shortcomings: Higher cost, requiring precision processing, and difficult to manufacture.

Liquid-cooled optical machine

Advantages: Using liquid cooling technology, it can effectively reduce the temperature of the optical machine and improve stability and lifespan.

Shortcomings: Higher cost, high requirements on cooling system, and relatively complicated maintenance.

Fully enclosed optical machine

Good dust-proof effect: The closed design effectively prevents dust, impurities and other external substances from entering the optical system, keeping the projection effect clear.
Stable optical path: Since the closed design can prevent external factors from interfering with the optical system, the optical path is more stable and can maintain the projection effect for a longer period of time.
Extended lamp life: The enclosed design reduces the possibility of dust entering the lamp and optical components, helping to extend the life of the lamp and reduce the frequency of lamp replacement and maintenance costs.
Reduce maintenance frequency: Due to its good dust-proof effect, the enclosed optical engine reduces the need for maintenance inside the projector. Users can use the projector for a longer period of time without frequent cleaning or repairs.

Insufficient heat dissipation than an open design: A fully enclosed design may result in lower heat dissipation efficiency inside the projector, which may affect the stability and lifespan of the projector, especially when used for a long time and at high intensity.
Higher cost: Closed opto-mechanical designs usually require more complex processes and materials, so the cost may be higher compared to open designs.
