LIGHT-EMITTING DEVICE AND OLED DISPLAY PANEL - A simplified explanation of the abstract

This abstract first appeared for US patent application 17638866 titled 'LIGHT-EMITTING DEVICE AND OLED DISPLAY PANEL

Simplified Explanation

The patent application describes a light-emitting device and an OLED display panel. The device includes a charge generation layer consisting of an N-type electron generation layer, a P-type hole generation layer, and a metal activation layer positioned between them. The metal activation layer is in contact with the N-type electron generation layer and the P-type hole generation layer, activating a surface energy at the contact surfaces. This prevents the accumulation of charges and the formation of an electric field in the internal space, ultimately improving the performance and lifespan of the light-emitting device.

• The light-emitting device includes a charge generation layer with an N-type electron generation layer, a P-type hole generation layer, and a metal activation layer.
• The metal activation layer is in surface contact with the N-type electron generation layer and the P-type hole generation layer.
• The metal activation layer activates a surface energy at the contact surfaces.
• The activation of surface energy prevents the accumulation of charges and the formation of an electric field in the internal space.
• The technology improves the performance and lifespan of the light-emitting device.

Potential Applications

• OLED displays in electronic devices such as smartphones, tablets, and televisions.
• Lighting applications such as OLED lamps and panels.
• Signage and advertising displays.

Problems Solved

• Accumulation of charges in the internal space of the light-emitting device.
• Formation of an electric field that affects the performance and lifespan of the device.

Benefits

• Improved performance and lifespan of the light-emitting device.
• Enhanced efficiency and stability of OLED displays.
• Reduced risk of charge accumulation and electric field formation.

Original Abstract Submitted

A light-emitting device and an OLED display panel are provided. The light-emitting device includes a charge generation layer. The charge generation layer includes an N-type electron generation layer, a P-type hole generation layer, and a metal activation layer disposed between the two. The metal activation layer is in surface contact with of the N-type electron generation layer and the P-type hole generation layer. It activates a surface energy at contact surfaces, prevents an accumulation of charges to form an electric field in an internal space, and improves a performance and a lifespan of the light-emitting device.
