Display having a compensation film with light absorbing dye

Abstract:

An electronic device may have a display such as an organic light-emitting diode display. A compensation film may be used to correct the color shift in the display. The compensation film may include a layer of liquid crystals and dye aligned with the liquid crystals. The dye may be configured to absorb different amounts of light depending on an angle that the light passes through the compensation film. Higher angled light will have a longer path length through the compensation film and therefore more of the higher angled light will be absorbed by the dye. The dye may therefore compensate for the color shift that occurs at high viewing angles.
