Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices lack satisfactory performance in certain aspects, necessitating the development of a new display device that incorporates an image sensor to enhance functionality.
Innovation Solution
A display device with a display panel and at least one image sensor that includes a light-sensing element and a light-receiving element, where the image sensor overlaps the display region, allowing for improved light detection and sensitivity, potentially integrated with a flexible or non-flexible substrate and light-emitting units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an image sensor is integrated into the display device, then light sensitivity and image detection capability are improved, but device complexity increases
Solution Approach 1:
The patent integrates the image sensor directly into the display device structure, merging the display function and image sensing function into a single device. The sensor is positioned behind the display panel, allowing the display device to perform both display and image capture operations without requiring separate devices.
Solution Approach 2:
The display device is designed to perform multiple functions: displaying visual information and capturing images. By incorporating the image sensor with light-sensing and light-receiving elements into the display panel structure, the device achieves multi-functionality, allowing it to serve as both a display and an imaging device.
2Measurement precision
If the image sensor overlaps the display region, then image clarity and light detection effectiveness are improved, but manufacturing precision requirements increase
Solution Approach 1:
The image sensor is positioned in a different spatial dimension (behind the display panel) rather than side-by-side with the display region. This vertical stacking arrangement allows the sensor to overlap the display region in the vertical dimension while maintaining manufacturing feasibility, as it avoids the need for precise lateral alignment that would be required if the sensor were positioned adjacent to the display.
3Measurement precision
If light-receiving elements are disposed on light-sensing elements, then light detection capability is improved, but device complexity increases
Solution Approach 1:
The light-receiving elements are disposed on top of the light-sensing elements, creating a nested structure where one component is placed upon another. This nested arrangement allows the light-receiving elements to effectively channel light onto the light-sensing elements, improving detection capability while containing the complex structure within a compact vertical footprint.
