Means to reduce OLED transient response

A device comprising:

• an organic light emitting device (OLED) having a plurality of sub-pixels, where one or more sub-pixels of the plurality of sub-pixels comprise:
• a first emissive area and a second emissive area that are in a same sub-pixel of the one or more sub-pixels and are independently controllable;
• and
• a controller to control the first emissive area and the second emissive area,
• wherein the first emissive area is larger than the second emissive area, and
• wherein the controller is configured to control the second emissive area to have at least one selected from a group consisting of:
• (i) a higher brightness, and (ii) a higher current density than the first emissive area for a first sub-pixel luminance level that is less than a maximum luminance,
• wherein each emissive area in the same sub-pixel is powered by its own power supply line,
• wherein the first emissive area and the second emissive area are configured to emit the same emissive spectrum, and
• wherein the emissive spectrum of light emitted out of the device from a sub-pixel is the same whether the light is emitted from the first emissive area or the second emissive area in the sub-pixel.
