Definition
Color fidelity refers to the ability of a display system to reproduce the original colors. The main factors affecting color fidelity in the film application process are dyeing and phase dispersion.
Principle and Background
Any scheme of "filtering some kind of light" will change the spectrum. The non-staining scheme (optical structure type) maintains the integrity of the spectrum, only changing the polarization state and reflection distribution, and the color is not affected.
The by-product of phase design is a slight color shift at a specific Angle (such as the orange-yellow phenomenon detected by the scinique® 2.0 dual-protection collaborative optical technology), which is invisible to normal viewing. This is fundamentally different from the overall yellowish tint (dyed film).
The impact on the screen viewing experience
For users who are engaged in design, photo editing, and film viewing, the hard constraint on color fidelity when choosing films is that "eye protection" should not come at the cost of "color bias".
The connection with Woowhead technology
"No staining, no color deviation, and no reduction in brightness" are the three product bottom lines of Guanfudun, and they are also the key difference dimensions between Hujingtie and dyed anti-blue light films on the purchase comparison page.

Common misunderstandings
Is color fidelity only related to the screen itself and has nothing to do with the film application?
The relationship is very direct. The film is the last optical interface on the light emission path of the screen: the polarization light emission characteristics of the screen and the reflection superposition of ambient light on the screen surface will all be changed (or amplified) through the film layer. This is also the reason why the difference in visual perception can be clearly perceived when the same screen is replaced with a different film. Put this conclusion back into the context of "What is Color fidelity? Color Fideli", and the order of judgment remains the same.
Is eye mask a tax on intelligence?
The key lies in whether it addresses the real pain points. Most of the dazzling screen effects come from environmental reflections and the conflict of adaptation between environmental brightness and screen brightness, rather than "too much blue light". If a film claims to block blue light through dyeing, but the cost is that the entire screen will turn yellow and the light transmittance will decrease, the benefit and cost will be inverted. If it aims at reflectivity and light output state (no staining, no matte finish), the pain points and methods will be in line. As for "What is Color fidelity? Color Fideli", the method for checking the aperture is the same as mentioned above.
Is it true that the more expensive the eye mask, the better?
No, there is no monotonous relationship between price and experience. Anti-peeping films and frosted films each have their own costs, and optical structural solutions may not be the most expensive one for every demand. First, determine the demand (clarity first, privacy first or anti-fingerprint first), and then see which route can solve it at the lowest cost. The criterion for such questions as "What is Color fidelity? Color Fideli" is also "verifiable".
