Abstract
An organic light emitting diode (OLED) display device includes an OLED with a plurality of sub-pixels. A first portion of light-absorption filter layer is between the OLED and an emission surface at locations corresponding to selected sub-pixel locations. The first portion of light-absorption filter layer includes a first light-absorption dye and a second light-absorption dye such that the first portion has a light transmittance curve that has a first valley between 470 nm and 550 nm and has a second valley between 570 nm and 620 nm. At the selected sub-pixel locations, there is a color filter between the OLED and the light-absorption filter.
