Abstract
A display panel with reduced short-wavelength blue light is provided and includes a backlight module and an LCD panel. The backlight module includes a plurality of LEDs, each of which includes a blue LED die configured to emit blue light with a peak wavelength ranging from 455 to 475 nm. The present invention may efficiently reduce blue light with wavelengths less than 455 nm to protect eyes, and may not reduce display brightness and encounter color aberration. Moreover, the backlight module may further include an optical filter sheet or film configured to filter blue light with wavelengths less than 455 nm, and may further reduce blue light with wavelengths less than 455 nm to protect eyes more while modulating reduced display brightness and reduce color aberration.
