AI Technical Summary

Technical Problem

Existing display devices are prone to speckle artifacts in strong light environments, which affects image quality.

Method used

Introducing separation regions into the grid-shaped layout of the touch electrodes, by setting separation regions with curved portions in or near the connection regions, reduces external light reflection and lowers the visibility of spot artifacts.

Benefits of technology

Maintain high image quality in bright light environments, reduce speckle artifacts caused by external light reflection, and ensure signal continuity and touch sensing performance.

Abstract

A display apparatus and an electronic device are disclosed. The display apparatus includes a plurality of emission areas configured to emit light and a touch electrode arranged to sense a touch. The touch electrode includes a first extension area extending mainly in a first direction, a second extension area extending mainly in a second direction crossing the first direction, a connection area in which the first extension area and the second extension area are connected, and a separation area closer to the connection area than to a center of the first extension area in a longitudinal direction of the first extension area or a center of the second extension area in a longitudinal direction of the second extension area.
