ORGANIC LIGHT EMITTING DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240122027 titled 'ORGANIC LIGHT EMITTING DISPLAY DEVICE

Simplified Explanation

The patent application describes an organic light emitting display device with a touch electrode unit that includes first touch electrodes and second touch electrodes arranged in different directions, forming touch pattern unit blocks repeated across the display. The touch electrode unit is disposed over the pixels and spacers on the substrate.

• The organic light emitting display device includes a substrate with pixel areas and a pixel separating area.
• A plurality of pixels are present on the substrate.
• Spacers are located in the pixel separating area, spaced apart from each other.
• The touch electrode unit consists of first and second touch electrodes arranged in different directions.
• Touch pattern unit blocks are formed by portions of neighboring first and second touch electrodes.
• Spacer pattern unit blocks are created by a plurality of spacers, each smaller than a touch pattern unit block.
