Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LCD display splicing technologies suffer from unavoidable bezel gaps, which hinder seamless splicing and compromise the display effect due to the inability to achieve 8K resolution.
Innovation Solution
A display module and seamless splicing display device are designed with a compensation display component in the bezel area, driven by a bezel driving circuit and integrated with an array substrate driving circuit through metal wiring on the lateral surface, eliminating the need for additional control circuits and reducing module thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If LCD display screens are spliced together to form large-screen displays, then the display area is increased, but black splicing gaps appear between the bezels of adjacent screens
Solution Approach 1:
The patent extracts the driving circuit function from the traditional bezel area and relocates it to the lateral surface of the display panel. By removing the bezel structure that houses the driving circuit and placing the circuit on the side surface with metal wiring, the display area can extend to the edges without requiring bezel gaps for circuit placement, thereby eliminating the splicing gap issue while maintaining large display area
Solution Approach 2:
The patent transitions the driving circuit from a two-dimensional planar layout on the front surface (bezel area) to a three-dimensional arrangement on the lateral surface. The driving circuit is wrapped around the side edge of the display panel, utilizing the vertical dimension and side surface area, which allows the front display area to be maximized without compromising circuit functionality, thus enabling seamless splicing
2Length of moving object
If the bezel is compressed to reduce its width, then the splicing gap is reduced, but the bezel driving circuit becomes difficult to accommodate
Solution Approach 1:
The patent resolves the contradiction by moving the driving circuit from the front surface (2D plane) to the lateral surface (3D space). The circuit is wrapped around the side edge of the display panel, utilizing the vertical dimension and side surface area. This allows the bezel width to be minimized or eliminated at the front while the driving circuit is accommodated on the side surface, solving both the splicing gap issue and the circuit accommodation problem simultaneously
3Area of stationary object
If additional control circuits are added to drive the compensation display component, then the bezel area can be utilized, but the module thickness increases
Solution Approach 1:
The patent eliminates the need for additional control circuits by integrating the driving function into the existing array substrate driving circuit. The driving circuit is relocated to the lateral surface and wrapped around the side edge, utilizing the side surface area instead of adding thickness. This approach utilizes the bezel area effectively while maintaining thin module thickness by avoiding additional circuit layers
4Object-generated harmful factors
If LED splicing is used to achieve seamless splicing, then the splicing gap is eliminated, but the 8K resolution cannot be satisfied
Solution Approach 1:
The patent makes the LCD display technology multi-functional by combining it with both high resolution capabilities and seamless splicing capabilities. By relocating the driving circuit to the lateral surface, the LCD technology can achieve both functions that were previously mutually exclusive, eliminating the need to choose between LED's seamless splicing and LCD's high resolution
