Clinical studies have shown that blue light
can cause damage to the retina. TCL T771K3 uses NXTPAPER screen to achieve a
low blue light mode. Requiring no manual settings, the screen color temperature
will remain unchanged during use, thus providing users with comprehensive low
blue light eye protection.
Note: Due to the special material of the NXTPAPER screen, it is not available to stick a tempered film or protective film on it.
