RGBW OLED DISPLAY FOR EXTENDED LIFETIME AND REDUCED POWER CONSUMPTION

摘要

PURPOSE: An RGBW OLED display for reducing power consumption and increasing a lifetime thereof is provided to reduce the power consumption of a device by increasing an area of a sub pixel which emits white light. CONSTITUTION: A hole injection layer(120), a hole transport layer(125), and an electron blocking layer(130) are formed on a substrate(110). An emission layer(135) and a hole blocking layer(140) are formed on the electron blocking layer. An electron transport layer(145) and an electron injection layer(150) are formed on the hole blocking layer. A protection layer(155) and a cathode(160) are formed on the electron injection layer. The cathode includes a first conductive layer(162) and a second conductive layer(164).
