Background technique

Color temperature is the measure of the light color of the light source. Its unit is K (Kelvin). It is the human eye's perception of illuminants or white reflectors. The color temperature preference depends on the individual. This is the same as the scenery we see in our daily life. For example, people who are close to the equator see an average color temperature of 11000K (8000K (dusk) ~ 17000K (noon)), so they prefer high color temperature (it looks more real), on the contrary, people with higher latitudes People in regions with an average color temperature of about 6000K prefer low color temperature (5600K or 6500K), that is to say, if a TV with a high color temperature is used to display the scenery of the Arctic, it will look blue; on the contrary, if a TV with a low color temperature is used If you watch a subtropical TV with a color temperature, it will feel a bit reddish.

At present, the color temperature of the screen of the mobile phone is generally set by default according to the screen manufacturer when it leaves the factory, and it is difficult to adjust. However, there are big differences in the color temperature of screens preferred by users in different regions. Some prefer cooler colors and some prefer warmer colors; no the same. Therefore, a uniform and monotonous screen color temperature is difficult to bring a good visual experience to users.
