Different to the conventional visible-CCFL backlight, UV excited flat lighting (UFL) applies UV-CCFL to irradiate 254 nm wavelengths to excite extrinsic phosphor layer to perform uniform and flat lighting for LCD-TV applications. UFL can yield longer life time due to less phosphor damage. Additionally, high color rendering, minor color deviation, wider FWHM (Full width at half maximum) angle, and better lamp mura relaxation, were demonstrated to achieve a high quality display with slim backlight module.
