Solution Overview
Problem
Existing display devices and electronic appliances often become visual noise and lack intuitive operability, failing to harmonize with their environment and provide a natural touch experience, especially in spaces where relaxation is desired.
Innovation Solution
An operation display panel incorporating a thin layer made of natural materials or materials mimicking natural appearance and touch, with integrated touch sensors, allowing for intuitive operation and visibility control through light transmittance and design, including a transparent conductive film and light guide for enhanced visibility and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a display device is made visible and functional, then operability and information display are improved, but visual noise and environmental harmony are worsened
Solution Approach 1:
The display panel incorporates different transparency regions: transparent regions for operational areas that require touch input, and opaque or translucent regions for display areas that should remain visually harmonious when not in use. This local differentiation allows the display to be functional where needed while maintaining aesthetic harmony in other areas.
Solution Approach 2:
The display panel dynamically changes its transparency characteristics based on operational state. During normal operation, the panel maintains natural appearance. When touch input is detected or during active display periods, the transparency is adjusted to enhance visibility and interactivity, creating a dynamic adaptation between aesthetic and functional requirements.
2Shape
If a natural material thin layer is used to enhance designability and natural touch, then aesthetic harmony and touch quality are improved, but display visibility and operational clarity are worsened
Solution Approach 1:
The natural material thin layer is applied selectively: fully transparent in regions requiring high visibility and touch sensitivity, and with varying transparency in regions where aesthetic appearance is prioritized. This localized application resolves the conflict between natural appearance and display visibility.
Solution Approach 2:
The transparency parameter of the thin layer is optimized to specific ranges (1-50% light transmittance) that balance aesthetic appearance and display visibility. By controlling the transparency parameter within this range, the system achieves both natural appearance and sufficient visibility for the display function.
3Illumination intensity
If the thin layer transparency is increased to improve visibility, then display clarity is improved, but natural appearance and ambient harmony are worsened
Solution Approach 1:
Different transparency levels are applied to different regions of the panel: higher transparency (better visibility) in operational areas where function is prioritized, and lower transparency (better natural appearance) in aesthetic areas where harmony with the environment is prioritized.
Solution Approach 2:
The display panel uses a composite structure combining the natural material thin layer with underlying display components. This composite design allows the natural material to provide aesthetic appearance while the underlying layers ensure display clarity, with the overall system achieving both goals through material composition.
4Ease of operation
If touch sensors are integrated behind the thin layer for intuitive operation, then ease of operation is improved, but manufacturing complexity and sensor sensitivity are worsened
Solution Approach 1:
The touch sensor layer is merged with the natural material thin layer into a single integrated structure. The touch-sensitive coating is applied directly to the back surface of the thin layer, combining aesthetic and functional layers into one component, thereby reducing overall device complexity while maintaining intuitive operation.
Solution Approach 2:
The transparent conductive film serves as an intermediary between the natural material thin layer and the touch sensing function. It allows the natural material to maintain its aesthetic appearance while enabling capacitive touch sensing through its conductive properties, bridging the gap between form and function.

AI summary
The present invention provides a product with an operation display panel incorporated therein, which naturally harmonizes with the environment to not create visual noise for a user and allow the user to operate the operation display panel intuitively while feeling a natural material. A thin layer, made of a natural wood, natural fiber, natural leather, or natural stone, or a resin, synthetic fiber, synthetic leather or artificial stone created by imitating the appearance and touch of a natural material, is provided on the peripheral surface of a housing so that the thin layer covers at least the entire front surface of a display panel. A touch sensor incorporated comes in contact with the front surface of the panel. The thickness of the thin layer and the luminance of the panel are designed to allow the user to view the content displayed on the panel.
