Unanswered Questions
How does this technology improve touch sensitivity compared to existing solutions?
This technology enhances touch sensitivity by utilizing a reverse tapered shape in the first touch insulating pattern, allowing for more precise touch detection near the substrate's surface.
What advantages does the reverse tapered shape of the first touch insulating pattern provide in terms of light sensing capabilities?
The reverse tapered shape helps to minimize interference with incident light, ensuring accurate sensing by the light sensing portions on the substrate.
Original Abstract Submitted
A device comprises a substrate, a plurality of emission portions disposed on the substrate and emitting light, a plurality of light sensing portions disposed on the substrate and sensing an incident light, a bank layer partitioning the plurality of emission portions and the plurality of light sensing portions, and a touch sensing layer disposed on the bank layer. The touch sensing layer comprises a first touch insulating pattern disposed on the bank layer and partitioning a light opening overlapping the plurality of light sensing portions and a touch electrode disposed on the first touch insulating pattern. A cross-sectional shape of the first touch insulating pattern has a reverse tapered shape having a width that decreases towards a top surface of the substrate.
