AI Technical Summary

Technical Problem

Existing display devices are designed to effectively transmit light and reduce the impact of external light on internal configurations while maintaining the display area, especially in areas containing sensors.

Method used

The display device design with a transmissive window ensures effective light transmission and protection of internal components by setting a transmissive part in the first area of ​​the display panel and covering a portion of the thin-film transistor layer in the pixel limiting layer of that area, combined with the design of a light blocking layer and an insulating layer.

Benefits of technology

This technology enables display devices to transmit light while reducing the impact of external light on internal components, improving external visibility and protecting the internal structure, and adapting to the integration of multiple sensors.
