Display Apparatus, Display Module, and Electronic Device - A simplified explanation of the abstract

This abstract first appeared for US patent application 17768150 titled 'Display Apparatus, Display Module, and Electronic Device

Simplified Explanation

The display apparatus described in the patent application has a photoelectric conversion function with high sensitivity, increasing the light extraction efficiency of the device. It includes a light-emitting device, a light-emitting and light-receiving device, a first lens, and a second lens. The light-emitting device emits light of a first color, while the light-emitting and light-receiving device emits light of a second color and converts light of the first color into an electric signal. The emitted light from the light-emitting device exits the display apparatus through the first lens, and external light enters the light-emitting and light-receiving device through the second lens.

• Light-emitting device emits light of a first color
• Light-emitting and light-receiving device emits light of a second color and converts light of the first color into an electric signal
• First lens allows emitted light to exit the display apparatus
• Second lens allows external light to enter the light-emitting and light-receiving device

Original Abstract Submitted

A display apparatus having a photoelectric conversion function with high sensitivity is provided. The light extraction efficiency of the display apparatus is increased. The display apparatus includes a light-emitting device, a light-emitting and light-receiving device, a first lens, and a second lens. The light-emitting device has a function of emitting light of a first color. The light-emitting and light-receiving device has a function of emitting light of a second color and a function of receiving light of the first color and converting it into an electric signal. The light emitted by the light-emitting device is emitted to the outside of the display apparatus through the first lens. Light enters the light-emitting and light-receiving device from the outside of the display apparatus through the second lens.
