Selected Features

OLED Display

Sony KD-55AF9 has an organic light-emitting diode (OLED) display. This is a self-emissive display which can completely turn off individual pixels leading to the ideal black levels and better contrast during HDR compared to any LCD displays. OLED displays also have better viewing angle than IPS panels. However, OLEDs are not able to achieve such high brightness as modern LCD displays.
