AI Technical Summary
When the existing display device expands the display area, the optical sensor overlaps the display panel, which makes it difficult to detect the light amount and makes it difficult to realize touch detection without affecting the light transmittance.
A touch sensing panel is designed, which contains two different sensing areas, overlapping and non-overlapping areas with the optical sensor, and a grid pattern is formed using multiple conductive patterns and low reflective layers to ensure the overlapping areas of the optical sensor. The conductive pattern thickness is smaller than the non-overlapping area, enhancing light transmittance and touch detection capabilities.
High light transmittance and effective touch detection in the overlapping area of the optical sensor are realized, the convenience and reliability of the display device are enhanced, and the penetration of the optical signal and the accuracy of touch sensing are ensured.

[0040] It will be understood that the terms "first", "second", "third", etc. are used herein to distinguish one element from another element, and these elements are not limited by these terms. Therefore, a "first" element in an embodiment may be described as a "second" element in another embodiment.
[0041] It should be understood that descriptions of features or aspects within each embodiment should typically be considered as available for other similar features or aspects in other embodiments, unless the context clearly dictates otherwise.
[0042] As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.
