Display Device and System - A simplified explanation of the abstract

This abstract first appeared for US patent application 18417153 titled 'Display Device and System

Simplified Explanation

The display device described in the abstract is a multifunctional device that includes a photosensing function, biometric authentication function (such as fingerprint authentication), and touch panel function. It consists of a first substrate, a light guide plate, light-emitting elements, and a light-receiving element. The first light-emitting element emits visible light through the light guide plate, while the second light-emitting element emits infrared light to a side surface of the light guide plate. The light-receiving element receives both the visible and infrared light and converts them into electric signals.

• The display device has a photosensing function.
• The display device includes a biometric authentication function, such as fingerprint authentication.
• The display device also has a touch panel function.
• The device consists of a first substrate, a light guide plate, light-emitting elements, and a light-receiving element.
• The first light-emitting element emits visible light, while the second light-emitting element emits infrared light.
• The light-receiving element converts both visible and infrared light into electric signals.
