Why does the anti glare screen look so blurry?
Date:2025-11-05
The anti glare screen may not look as clear, which is the compromise and cost that must be paid to achieve its core function of eliminating glare.
This is not due to poor quality of the screen itself, but rather an inevitable result of its physical characteristics. We can understand it through a simple metaphor:
Imagine looking at the image behind you through a completely clean glass (representing a high gloss screen) and a frosted glass (representing an anti glare screen). The picture after cleaning the glass has bright colors and sharp edges; The image after frosted glass will feel a bit hazy, and the purity of details and colors will decrease.
Let's break down in detail why there is such an "unclear" feeling:
Core reason: The light has been 'scattered'
The surface of an anti glare screen is not absolutely smooth, but has countless microscopic and uneven concave convex structures. This structure is where its "anti glare magic" lies and also the root cause of "blurriness".
Comparative dimension | High gloss screen | Anti glare screen |
Surface state | Absolutely smooth, like a mirror surface | Microscopic roughness with concave convex particles |
Light reflection | Mirror reflection: Light is concentrated and reflected in one direction, forming a dazzling spot. | Diffuse reflection: The incident light is scattered by surface irregularities and reflects softly in all directions. |
Core cost | Completely unclear under strong light, with severe reflection. | Sacrificing some sharpness and color saturation, there is a "hazy feeling". |
The specific impact of this "dispersal" effect:
Reduced sharpness of details
The light emitted by each pixel on the screen undergoes slight diffusion when passing through the rough AG surface, resulting in a small overlap with the light from adjacent pixels.
Your feeling: The edges of text and images may feel less sharp, a bit blurry or hazy. Especially when displaying very small text or lines, this feeling will be more pronounced.
Decreased color saturation and contrast
The same light scattering effect can also make "black" less pure, as some ambient light is scattered to areas that should have been black, causing black to appear a bit "gray".
Your feeling: The overall picture doesn't look "transparent" enough, the colors are not as bright and vibrant, as if covered with a very thin, semi transparent white veil.
"Foggy "
This is a professional term used in the industry to describe the strength of AG coatings. The higher the haze value, the better the anti glare effect, but the more the clarity and color saturation of the picture are sacrificed. The 'unclearly' you feel is largely a reflection of this' haze '.
So, why do we still choose anti glare screens?
This is a typical 'balancing' problem. We traded absolute picture quality for the more important ability of being able to see clearly under any lighting conditions.
In light controlled indoor environments such as home theaters and professional design studios, high gloss screens can provide the most stunning picture quality.
But in multi light environments such as industrial control, outdoor use, and offices, the reflection on high gloss screens will make it impossible for you to see the screen content, and at this time, the picture quality is meaningless no matter how good it is. At this point, the value of the anti glare screen is reflected - it ensures the readability of information and the reliability of operation.
How to choose?
If your usage environment has complex and strong lighting, or requires prolonged screen staring, then an anti glare screen is necessary. Its advantages (no glare, no fatigue, anti fingerprint) far outweigh the small loss in image quality.
If your job has extreme requirements for the accuracy of image colors and sharpness of details (such as photography retouching, medical imaging diagnosis), you may need to choose a high-quality AG screen with extremely low "haze" or use a high gloss screen directly under controllable ambient light.
Summary: The "blurriness" of anti glare screens is an inherent characteristic of their working principle. This is not a malfunction, but a design trade-off made to enhance functionality and usability, with the aim of ensuring reliable visibility of core content under harsh lighting conditions.
