LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17932421 titled 'LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME
Simplified Explanation
The abstract describes a light-emitting device that includes an OLED substrate with stacked blue and green emission units, emitting blue and green light. It also includes a color control unit in the path of the emitted light. The green emission unit consists of two compounds emitting light with different spectra and peak wavelengths.
- The light-emitting device includes an OLED substrate with stacked blue and green emission units.
- The OLED substrate emits blue and green light.
- A color control unit is present in the path of the emitted light.
