Luminance Control of Organic Light-Emitting Diodes Using an Organic Bistable Memory Device
The luminance control of organic light-emitting diodes (OLEDs) using an organic bistable memory device was investigated. A quantum dot embedded organic bistable memory device was connected to the OLED instead of a common thin film transistor to manage the luminance of the OLEDs. Multilevel luminance control of the OLEDs could be enabled by simply controlling the setting voltage of the organic bistable memory device. High luminance was obtained at the writing voltage corresponding to the high current state, while low luminance was obtained at the erasing voltage corresponding to the low current state.
