Many people face a problem when using a projector: they can't see clearly during the day. This is mainly because the projector displays the picture, which is easily affected by ambient light. So, how to solve this problem?
Projector brightness is one of the important indicators of projector performance, which determines the clarity and degree of image accessibility.
In a bright room or in a brightly lit environmentIf the projector is not bright enough, the projected image may appear dim, blurry, or even impossible to see
On the left is a brightness of 2450CVIAlumens dangbeiX5; On the right is a projector with a lumens of 800cvia.Therefore, a high-brightness projector can better resist the interference of ambient light, and you can see that even in the daytime when there is a lot of light, the picture effect is still very good; And low-brightness projectors can basically only see shadows.
1) Money-saving method: Turn off the lights and draw the curtains
Reducing the brightness of the ambient light is the most cost-effective way to do it. The interference of ambient light can be reduced by closing the curtains and turning off the lights, so that the projected image can be more clearly visible.
2) Improvement method: change the projection and add the curtain
1. Replace the high-brightness projector
The most straightforward way is to buy a high-brightness projector. There are already some projectors on the market with brightness exceeding 2000 CVIA lumens, which can present clear images during the day.
How to choose a high-brightness projector?
First of all, choose different brightness according to different usage scenarios:
Because,High-brightness projectors** will also be relatively high,If you only use it in a dark or low-light environment,It will be a bit of overperformance,Resulting in low cost performance。
However, if you often need to use a projector during the day, it pays to invest in a high-brightness projector that is more resistant to ambient light.
In general, the correspondence between the brightness of the projector and the use environment is as follows——
Bedroom dark environment: choose 300-500cvia lumens, corresponding to the projector** in 100-2000Secondly, be sure to pay attention to the brightness unit:The full name of the CVIA brightness standard is "Technical Requirements and Test Methods for Projector Light Output", which is the first group standard specifically related to the brightness of projectors in China, compared with the ANSI lumen unit mainly used beforeCVIA lumens measurement standards are more stringent, the annotation is more scientific and more referential.Bedroom lowlight, living room dark environment: choose 500-1000cvia lumens, corresponding to the projector** in 1000-4000
Bedroom lights, living room low-light environment: 1000-1500cvia lumens, corresponding to the projector ** in 3000-5000
Living room screen environment: 1500-2000cvia lumens, corresponding to the projector** in 4000-7000
Living room daylight environment: 2000CVIA lumens or more, corresponding to the projector ** in 4000-10000
Previously, projectors mainly used ANSI lumen units, which were developed by the National Institute for Standardization to measure the luminous flux of projectors. There are many loopholes in this method, such as ignoring the projection distance of different focal length projectors, ignoring air loss, etc. Many unscrupulous businesses have exploited loopholes, resulting in a serious situation of false projector brightness. Other light source lumens, lumens and other units, you can directly avoid lightning.
Of course, when choosing a projector, in addition to considering brightness, you also need to consider other performance indicators, such as resolution, chip, memory, etc. These metrics all affect the quality and effectiveness of the projected image.

2. Use anti-light curtains
The use of anti-light curtains is one of the effective ways to improve the projection effect. The anti-light curtain has a good shading ability, which can effectively block external light and reduce its interference to the projected picture, thereby improving the contrast and color performance of the picture.
At present, there are two main types of anti-light curtains commonly found on the market:Black raiser and Fresnel curtains.
The black grid uses a black and white prism, in which the ambient light from the top will be absorbed by the black side, reducing its impact on the projector picture; The white side will reflect the light from the projector in a directional direction and gain the image.
Its characteristic is that the black grid anti-light curtain is only suitable for ultra-short throw projectors and uses the table projection method, which is more convenient to install and has advantages.
The surface of the Fresnel anti-light screen is covered with a semi-circular fan-shaped thread structure from large to small, which can effectively eliminate the ambient light interference from the upper and left and right directions, and can reflect the projector light in the lower center for directional reflection gain to improve the picture effect.
It is characterized by a smaller viewing angle than the black raster screen, but the anti-light gain effect is a little better, and ** is relatively high.
When choosing an anti-light curtain, you need to consider it comprehensively according to your needs and budget.
All in all, if you often need to use your projector during the day, you may want to consider replacing it with a high-brightness projector or using a light-resistant screen or reducing the brightness of the ambient light to improve the projection.
