Solution Overview
Problem
Existing display devices face challenges in improving image quality and withstanding physical impacts, especially when used with touch input systems, as they often suffer from air layer interference and damage from applied pressures.
Innovation Solution
A display device design that incorporates a touch panel closely adhered to a display panel with an elastic adhesive layer, pressure sensors between the panels, and a cushion member to absorb impacts, allowing pressure transfer and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch panel is used for easy signal input, then ease of operation is improved, but the display panel becomes vulnerable to damage from applied pressure
Solution Approach 1:
The patent introduces a cushion member positioned between the display panel and the pressure sensor, which serves as a protective element that absorbs and distributes applied pressure before it reaches the fragile display panel. This cushioning structure prevents direct transmission of impact forces while still allowing the pressure sensor to detect touch inputs, thereby resolving the contradiction between touch sensitivity and panel durability
Solution Approach 2:
The cushion member acts as an intermediary element between the touch input source and the display panel. It mediates the interaction by providing a compliant interface that protects the display panel from direct mechanical stress while maintaining the functional connection needed for pressure sensing, thus enabling both easy operation and structural strength
2Illumination intensity
If an adhesive layer is used to eliminate air layers between panels, then image quality is improved, but the device becomes more complex
Solution Approach 1:
The patent combines the adhesive function with the cushioning function into a single integrated layer. The adhesive layer is designed to simultaneously eliminate air gaps between panels for optimal optical contact while incorporating elastic properties to provide cushioning protection. This merging of functions achieves improved image quality without proportionally increasing structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances image quality by eliminating air layers and protects the display panel from damage, enabling accurate touch signal input while reinforcing the device against physical impacts.
Implementation Method 1
The adhesive layer includes a resin and so on. As such, an air layer existing between the touch and display panels is eliminated.
Implementation Method 2
the display panel is provided with a cushion member. The cushion member reduces an impact applied to the display panel.
Implementation Method 3
a pressure conductor configured to expand from the touch panel and to transfer the pressure to the sensors.

AI summary
Disclosed is a display device. The display device includes: a touch panel; a display panel in close contact with the lower surface of the touch panel; and a plurality of sensors arranged under the touch panel and configured to sense a pressure which is applied to the touch panel. The display device can improve the picture quality by bring the touch panel into close contact with the display panel. Also, the display device can input a signal, such as a touch or others, by sensing a pressure, which is applied to the touch panel, using the sensors.
