Transparent Display Panel with Apertured Peripheral Light Blocking

Solution Overview

Problem

Conventional transparent display devices face challenges in achieving a fully transparent surface due to the non-transparent peripheral areas that house drivers and signal lines, which obstruct the view and reduce the transparent surface area.

Innovation Solution

Incorporating a second light blocking member with apertures in the peripheral area of the display panel, allowing signal lines and drivers to be concealed while maintaining transparency by using a perceptively transparent design, thereby expanding the transparent area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Difficulty of detecting and measuring

If a light blocking member is used to cover drivers and signal lines in the peripheral area, then the drivers and signal lines are concealed, but the transparent surface area is reduced

Engineering Contradiction:

Improveconcealment of drivers and signal linesVSAvoidtransparent surface area

Core Design Contradiction:

Difficulty of detecting and measuringVSArea of stationary object

Solution Approach 1:

The light blocking member in the peripheral area is designed with a porous structure containing multiple apertures. This allows the member to block light and conceal the drivers and signal lines while still permitting light transmission through the apertures, thereby maintaining the perception of transparency and preserving the transparent surface area.

Inventive Principle:

Principle #31Porous materials

2Reliability

If the peripheral area is made non-transparent to house drivers and signal lines, then reliable connection is achieved, but the entire surface transparency is compromised

Engineering Contradiction:

Improveconnection reliability of drivers and signal linesVSAvoidoverall transparency of display surface

Core Design Contradiction:

ReliabilityVSIllumination intensity

Solution Approach 1:

The light blocking member is specifically positioned in the peripheral area rather than across the entire display surface. This localized approach allows the peripheral area to provide reliable concealment for drivers and signal lines while the central display area maintains full transparency, thus resolving the contradiction between connection reliability and overall surface transparency.

Inventive Principle:

Principle #3Local quality

3Difficulty of detecting and measuring

If the light blocking member covers the entire peripheral area, then complete concealment is achieved, but the transmitting area is reduced

Engineering Contradiction:

Improveconcealment effectivenessVSAvoidtransmitting area

Core Design Contradiction:

Difficulty of detecting and measuringVSArea of moving object

Solution Approach 1:

The light blocking member incorporates multiple apertures throughout its structure, creating a porous configuration. This design enables the member to provide complete concealment of the drivers and signal lines from certain viewing angles while simultaneously allowing light transmission through the apertures, thereby preserving the transmitting area and maintaining the perception of an entirely transparent surface.

Inventive Principle:

Principle #31Porous materials
