I suddenly have a thought about the relationship between screen protectors and temporal dithering, and I found this from google search:
A screen protector can affect temporal dithering, particularly if it's a matte or anti-glare type. These protectors can disrupt the regular pixel patterns created by temporal dithering, potentially reducing or eliminating the eye strain some individuals experience.
Here's why and how:
Temporal Dithering:
Temporal dithering is a technique used in displays to simulate more colors than the display actually supports by rapidly switching between similar colors on adjacent pixels.
Matte/Anti-glare Protectors:
These protectors have a textured surface that diffuses light and reduces reflections.This texture can interfere with the precise switching patterns of temporal dithering.
According to what is mentioned here, it seems that matte screen protectors have a positive impact on the screen comfort. However, I would rather come out with the following working theory:
As the texture of screen protectors can interfere with the precise switching patterns of temporal dithering, it follows that there is certain type of screen protector that interact "appropriately" with certain screens to produce the optimal comfort of viewing experience.
In other words, the conclusion is not whether matte or clear screen protector is better, but that we have to try to find one that works by trials and errors. By chance we may find a screen protector that can offset the effects of temporal dithering.
