Solution Overview

Problem

Existing transparent display apparatuses lack the capability to extend their application use beyond basic communication between individuals, limiting their functionality and versatility.

Innovation Solution

A transparent display apparatus is designed with a first and second substrate, a display layer with pixels that can transition between transparent and non-transparent states, and a controller that manages the display layer's state to allow image display from both sides while controlling first lighting to ensure the image is visible only from the intended side.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the display layer is made transparent to allow background visibility, then transparency is improved, but image visibility to specific users deteriorates

Engineering Contradiction:
ImprovetransparencyVSAvoidimage visibility control
Core Design Contradiction:
Illumination intensityVSLoss of information

Solution Approach 1:

The patent applies local quality by controlling the transparency state of individual pixels in the display layer based on user position and image importance. Different regions of the display layer have different transparency states, allowing the system to maintain overall transparency while selectively obscuring specific areas to control which users can see which images.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements dynamics by making the transparency state of the display layer changeable and controllable in real-time. The controller adjusts the transparency of pixels dynamically based on detected user positions, image attributes, and privacy requirements, transitioning between transparent and non-transparent states as needed.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the display apparatus allows image viewing from both sides, then versatility is improved, but user privacy control deteriorates

Engineering Contradiction:
Improvebidirectional viewingVSAvoidprivacy exposure
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by assigning different transparency control strategies to different sides of the display apparatus. The controller determines which side (first or second surface) should have transparent pixels and which should have non-transparent pixels based on user positions and image sensitivity, allowing selective visibility from each side.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent introduces an intermediary control system that mediates between the conflicting requirements of bidirectional viewing and privacy protection. The controller acts as an intermediary that receives input about user positions and image attributes, then intelligently determines the appropriate transparency state for each pixel to balance accessibility and privacy.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Illumination intensity

If lighting is increased to improve image visibility, then image visibility is improved, but energy consumption increases

Engineering Contradiction:
Improveimage visibilityVSAvoidlighting energy consumption
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The patent applies partial action by selectively illuminating only those regions of the display that contain important images requiring visibility, rather than illuminating the entire display area. The controller determines which pixels need illumination based on image attributes and user positions, applying lighting only where necessary to maintain visibility while conserving energy.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A transparent display apparatus includes a display layer provided in a display region where a first substrate, a second substrate, and a display layer overlap, and a controller controlling a state of pixels of the display layer, an image displayed in the display region from a first surface side of the first substrate and a background on the first surface side are visible, and the controller controls state of first lighting, which lightens an inside of a first space, in causing the display layer to display the image toward a first user in the first space on the first surface side.
