Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices require separate devices for eye-tracking, which increases manufacturing complexity and cost, and existing solutions do not efficiently integrate infrared and camera units within the display panel.
Innovation Solution
An electronic apparatus is designed with an infrared ray unit and a camera unit integrated within the display panel, utilizing high and low transmittance areas to allow for infrared ray emission and reception without overlapping with display pixels, enabling gaze tracking without additional devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate devices are used for eye-tracking, then gaze tracking functionality is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent combines the infrared ray unit and camera unit into the display panel structure, merging previously separate eye-tracking devices with the display device. The infrared ray unit is disposed in a first region of the display panel while the camera unit is disposed in a second region, integrating multiple functions into a single device to reduce manufacturing complexity and cost.
2Device complexity
If infrared and camera units are integrated within the display panel, then manufacturing complexity is reduced, but space for pixel arrangement is limited
Solution Approach 1:
The display panel is segmented into different regions: a first region for the infrared ray unit, a second region for the camera unit, and a third region for pixel arrangement. This segmentation allows each component to occupy its designated space without interfering with others, enabling integration while preserving sufficient area for pixel arrangement in the third region.
3Reliability
If transmission areas are created for infrared emission and reception, then infrared functionality is enabled, but display pixel coverage is reduced
Solution Approach 1:
The display panel is divided into distinct functional regions: a first region containing the infrared ray unit with its transmission area, a second region containing the camera unit, and a third region dedicated to pixel arrangement. This segmentation ensures that transmission areas for infrared functionality are confined to specific regions, preventing them from encroaching on the pixel arrangement area in the third region.
Solution Approach 2:
Different regions of the display panel are assigned different optical properties: the first region has high transmittance for infrared rays to enable emission and reception, while the third region maintains standard display properties for pixel arrangement. This local differentiation of properties allows infrared functionality where needed without compromising the overall display pixel area.
