Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses lack the capability to integrate sensor functions effectively within their structure, limiting their versatility and functionality, especially in terms of image representation and connectivity with other display devices.
Innovation Solution
A display panel design that includes a first base layer with a display area and a sensor area, featuring a conductive layer of 1500 Å or more, positioned between two base layers, where the sensor area has auxiliary pixels and a transmission portion, allowing for increased connectivity and functionality by separating image display and sensor functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensor functions are integrated within the display area, then functionality and connectivity are improved, but image resolution may deteriorate
Solution Approach 1:
The display area is divided into display regions and a sensor area. The sensor area includes auxiliary pixels arranged in a grid pattern with transmission portions, separating sensor functions from main display functions. This segmentation allows the display apparatus to maintain high image resolution in display regions while integrating sensor capabilities in the sensor area without interfering with each other's performance.
2Reliability
If a conductive layer with thickness of 1500 Å or more is used, then electrical conductivity is improved, but manufacturing complexity increases
Solution Approach 1:
The conductive layer thickness is specifically set to 1500 Å or more to achieve the desired electrical conductivity for sensor operations. This parameter change ensures sufficient conductivity for the auxiliary pixels and sensor components while being incorporated into the existing multi-layer manufacturing process, thus balancing electrical performance requirements with manufacturing feasibility.
3Adaptability or versatility
If auxiliary pixels are positioned in the sensor area, then sensor functionality is improved, but display area is reduced
Solution Approach 1:
The sensor area with auxiliary pixels is integrated within the overall display structure by utilizing the vertical stacking arrangement and positioning the sensor area in a specific region. This dimensional arrangement allows the auxiliary pixels to be positioned below or adjacent to the main display pixels, enabling sensor functionality without significantly reducing the visible display area from the user's perspective.

AI summary
A display apparatus has an enlarged display area so that an image can be displayed in a sensor area. The display apparatus includes: a first base layer that includes a display area that includes a plurality of main pixels and a sensor area that includes a plurality of auxiliary pixels and a transmission portion; a conductive layer positioned on the first base layer and that corresponds to the plurality of auxiliary pixels; and a second base layer positioned on the first base layer with the conductive layer positioned between the second base layer and the first base layer. A resolution of an image displayed by the sensor area is lower than a resolution of an image displayed by the display area.
