Organic light emitting diode (oled) having improved stability, luminance, and efficiency
Organic light emitting diode (oled) having improved stability, luminance, and efficiency An organic light emitting diode (OLED) includes a relatively thin diamnond-like carbon (DLC) layer disposed between the anode and the hole transport layer to improve luminous efficiency and operating life time. The relatively thin DLC layer inhibits hole injection, which balances charge flow and improves efficiency, and increases the surface smoothness of the anode, which contributes to the increased operating life time.
