Solution Overview

Problem

Existing display devices with large screens face challenges in achieving a bezel-less structure while maintaining support stability and efficient heat dissipation, particularly in curved portions.

Innovation Solution

A curved display device design incorporating separate display panels for planar and curved portions, with a housing structure that includes a bracket and backcover for support, and a touch-sensing layer on the coverglass, along with an auxiliary display module for improved stability and heat dissipation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a single large display panel is used to achieve a bezel-less structure, then the screen area is maximized, but the support stability deteriorates due to the large size and weight of the coverglass

Engineering Contradiction:
Improvescreen areaVSAvoidsupport stability
Core Design Contradiction:
Area of stationary objectVSStability of the object's composition

Solution Approach 1:

The display panel is divided into multiple separate panels (first display panel and second display panel) that are arranged in a matrix configuration. This segmentation reduces the size of each individual panel, thereby improving support stability while maintaining the overall large screen area through the combined display surfaces.

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If the coverglass is extended to support touch operation on curved portions, then the touch area is increased, but the heat dissipation efficiency deteriorates in the curved portion

Engineering Contradiction:
Improvetouch areaVSAvoidheat dissipation efficiency
Core Design Contradiction:
Area of stationary objectVSTemperature

Solution Approach 1:

The display panel is divided into multiple separate panels (first display panel and second display panel) that are arranged in a matrix configuration. This segmentation reduces the size of each individual panel, thereby improving support stability while maintaining the overall large screen area through the combined display surfaces.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If separate display panels are used for planar and curved portions, then the support stability is improved, but the device complexity increases

Engineering Contradiction:
Improvesupport stabilityVSAvoiddevice complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The housing structure is designed to universally support multiple types of display panels (planar and curved) through a common mounting framework. The housing includes a rear housing and front housing that collectively provide support for both planar and curved display portions, reducing overall device complexity despite using separate panels.

Inventive Principle:
Principle #6Universality (Multi-functionality)
