Not only monitor devices, many projection devices now support low blue light mode as well. So what does projector low blue light mode mean? Why is it important for projectors to support low blue light mode?
The low blue light mode is a display mode that reduces the exposure of blue light to the eyes, thereby reducing certain visual fatigue. Blue light is a type of visible light whose radiation damage is second only to ultraviolet light, with wavelengths between 380 and 500 nanometers. Generally, blue light above 400 nanometers is a high-energy light, which is more likely to threaten eye health. In other words, blue light above 400 nanometers is considered harmful blue light. The low blue light mode is to control the blue light wavelength as low as possible.
In order to reduce the damage of blue light, in the past, the method adopted by many businesses was to film the display device. The anti-blue light film technology has a relatively low cost and can effectively prevent the penetration of blue light. Now, many display device manufacturers have introduced low blue light modes (some devices support night mode, which can also reduce blue light). Projector devices have also supported a low blue light mode for the past year or two.
Since blue light is harmful to the eyes, it is obviously important to choose a device with low blue light. Taking the projector as an example, the built-in low blue light mode of the projector will reduce the blue light in the standard mode, and the picture will be more inclined to warm colors, so that the damage to the human eye will be reduced. After the low blue light mode is turned on, the projection screen is warm, and the performance on the projector screen is very obvious. This also shows that the low blue light mode does have its role.
Now that we know that blue light above 400 nanometers can cause eye damage, and we know that low blue light mode is very important, how do we choose a low blue light device? Very simple, the first thing is to check whether the product meets the GB/T Technical Requirements for Blue Light Protective Films for Health and Light Safety Application or Technical Specifications for Evaluation of Electronic Products with Low Visual Fatigue. The second is to choose a larger screen and control the duration of eye use.
At present, many projector devices have passed the German Rheinland hardware-level low blue light certification or passed the evaluation of low-fatigue electronic products. When choosing a low blue light device, be sure to check whether it has passed the certification of a third-party laboratory.
