PHOTOSENSOR AND SENSOR EMBEDDED DISPLAY PANEL AND ELECTRONIC DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18317400 titled 'PHOTOSENSOR AND SENSOR EMBEDDED DISPLAY PANEL AND ELECTRONIC DEVICE

Simplified Explanation

The patent application describes a sensor-embedded display panel with a light emitting element and a photosensor on a substrate.

• The light emitting element includes a light emitting layer.
• The photosensor includes a photosensitive layer parallel to the light emitting layer.
• Both the light emitting element and the photosensor have separate portions of common auxiliary layers.
• The photosensitive layer has energy levels close to the energy levels of the common auxiliary layers.

Potential Applications

• Display panels with integrated sensors for brightness adjustment.
• Smart devices with adaptive display capabilities based on ambient light.

Problems Solved

• Simplified design for sensor-embedded display panels.
• Improved accuracy in light sensing for automatic brightness adjustment.

Benefits

• Enhanced user experience with automatic brightness adjustment.
• Efficient use of materials for sensor integration in display panels.

Original Abstract Submitted

A sensor-embedded display panel includes a light emitting element on a substrate and including a light emitting layer, and a photosensor on the substrate and including a photosensitive layer extending at least partially in parallel with the light emitting layer along an in-plane direction of the substrate. The light emitting element and the photosensor include separate, respective portions of each of first and second common auxiliary layers each extending continuously as a single piece of material under and on, respectively, each of the light emitting layer and the photosensitive layer. The photosensitive layer may include a light absorbing semiconductor having a HOMO energy level having a difference of less than about 1.0 eV from a HOMO energy level of the first common auxiliary layer and a LUMO energy level having a difference of less than about 1.0 eV from a LUMO energy level of the second common auxiliary layer.
