Solution Overview

Problem

The high cost of large touch control display devices makes it impractical to provide a single large display, and existing technologies do not effectively address the need for cost-effective solutions to display large images using multiple smaller devices cooperatively.

Innovation Solution

A touch control display device design that includes a display panel, an image compensation element, and a touch sensing structure, where the image compensation element uses light guiding channels and fibers to expand and distribute the image from the periphery display region to the non-display region, creating a larger visible image without a visible frame.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a single large touch control display device is provided, then the display size is large, but the cost is high

Engineering Contradiction:
Improvedisplay sizeVSAvoidcost
Core Design Contradiction:
Area of stationary objectVSEase of manufacture

Solution Approach 1:

The patent divides a large display into multiple smaller display panels arranged in a matrix configuration. Each panel is an independent touch control display device with its own frame, and multiple panels are connected via connection frames to form a composite large-screen display system. This segmentation allows using affordable small panels to achieve the cost-effectiveness of the invention while providing large display area through their collective arrangement.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If multiple small touch control display devices are used cooperatively, then the cost is reduced, but the display size is limited

Engineering Contradiction:
ImprovecostVSAvoiddisplay size
Core Design Contradiction:
Ease of manufactureVSArea of stationary object

Solution Approach 1:

The patent merges multiple small display panels into a unified large-screen display system through connection frames that join the panels together. The connection frames not only structurally connect the individual panels but also enable them to function as a single integrated display unit, effectively combining their individual display areas to create a large overall display area while maintaining cost-effectiveness.

Inventive Principle:
Principle #5Merging (Combining)

3Area of stationary object

If multiple display panels are connected to form a large display, then the display area increases, but visible frames appear between panels

Engineering Contradiction:
Improvedisplay areaVSAvoidvisible frame
Core Design Contradiction:
Area of stationary objectVSShape

Solution Approach 1:

The connection frames are designed with the same or similar color as the surrounding display panels to visually blend with them. This color matching technique makes the connection frames less noticeable and creates the optical illusion of a seamless, frame-less display, thereby maintaining the aesthetic appearance of a unified large screen while allowing multiple panels to be connected.

Inventive Principle:
Principle #32Color changes

4Area of stationary object

If the periphery display region is used, then the display area is increased, but the pixel density is lower

Engineering Contradiction:
Improvedisplay areaVSAvoidpixel density
Core Design Contradiction:
Area of stationary objectVSManufacturing precision

Solution Approach 1:

The patent applies different pixel densities to different regions of the display panels, with the periphery display regions having higher pixel density than the main display regions. This local quality variation ensures that even the border areas contributing to the overall display area maintain high image quality and visual clarity, thereby resolving the contradiction between expanding display area and maintaining pixel density.

Inventive Principle:
Principle #3Local quality

AI summary

A touch control display device includes a display panel, an image compensation element positioned on the display panel, and a touch sensing structure adjacent to the image compensation element. The touch sensing structure is configured to sense touch actions applied to the touch control display device. The display panel includes a main display portion and a periphery display portion. The image compensation element includes a compensation portion, and the compensation portion is configured to distribute the image of the periphery display portion to the outside of the periphery display portion away from the main display portion. The compensation portion includes a light incident surface, a light emitting surface, and a plurality of light guiding channels extending from the light incident surface to the light emitting surface. An area of the light emitting surface is greater than an area of the light incident surface.
