Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stereoscopic image displaying devices are bulky and difficult to miniaturize due to the need for a frame-shaped configuration of light emitting and sensing components, which limits their thickness and makes them unsuitable for small-sized electronic devices, and they require physical contact to detect operations, causing user dissatisfaction.
Innovation Solution
A stereoscopic image displaying device with a proximity sensor unit placed on the outer surface that detects object proximity based on parallax information from the video signal, allowing detection without physical contact and enabling a thinner design by integrating the sensor within the display panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a frame-shaped configuration of light emitting body and light sensing body is used to detect operations on stereoscopic images, then operation detection capability is improved, but device thickness increases and miniaturization becomes difficult
Solution Approach 1:
The patent merges the light emitting body and light sensing body into a single integrated sensor unit that is disposed within the display panel itself, rather than using separate frame-shaped components. This integration allows the sensor to detect operations at the imaging position of the stereoscopic image while maintaining a thin device profile suitable for mobile devices.
Solution Approach 2:
The patent transitions from a three-dimensional frame-shaped sensor configuration to a two-dimensional planar sensor arrangement that is embedded within the display panel. This dimensional change allows the sensor to function effectively while minimizing device thickness and enabling miniaturization for mobile applications.
2Ease of operation
If electrostatic capacitance type sensor is used to detect button operations in stereoscopic images, then operation detection is achieved, but physical contact is required causing user dissatisfaction
Solution Approach 1:
The patent replaces the mechanical contact-based electrostatic capacitance sensor with an optical sensor system that uses light emitting and sensing components. This substitution allows the sensor to detect operations (such as button presses in stereoscopic images) without requiring physical contact from the user, thereby eliminating the harmful factor of mandatory contact while maintaining operation detection capability.

AI summary
A stereoscopic image displaying device includes an outer surface that a detection target object approaches; a stereoscopic image generating unit that generates a three-dimensional stereoscopic image based on an input video signal, and a proximity sensor unit that is disposed on a side of the outer surface that is opposite to a side that the detection target object approaches and detects proximity of the detection target object to the outer surface based on a height that is a distance from the outer surface and is set based on parallax information included in the video signal.
