Display device having functionality of blue light filtering

摘要

A device having functionality of eye protection is disclosed, which principally comprises a display main body and a light parameter regulating unit. The light parameter regulating unit is adopted for regulating a color temperature (CT) of a specific light that is radiated from the display main body down to be below 3000K. Moreover, the specific light is eventually regulated down to have a minimum CT of 2000K, and an illuminance of the specific light is steppedly dimmed to be close to 0 lx. Experimental data have proved that, after being applied with the light parameter regulating process, a value of MPE of the specific light is largely increased, and a ratio of MSS is significantly lowered. In addition, when a user is watching the display device, the illuminance of the specific light can also be automatically adjusted to approach an illuminance of an ambient light.
