Solution Overview

Problem

Conventional display devices with liquid crystal technology face challenges in maintaining display quality due to the visibility of frame regions between multiple units, which can lead to a deterioration in the continuity of the display when arranged side by side.

Innovation Solution

The solution involves a display device configuration with a circuit layer on a substrate that includes scanning signal line driving circuits distributed across multiple regions, allowing for a reduction in the frame region by overlapping these circuits with pixel electrodes, thereby minimizing the visible frame and maintaining display continuity when multiple units are arranged.

1Area of stationary object

If multiple liquid crystal displays are arranged side by side to achieve a large screen, then the display size is increased, but the frame regions between units become visible and display continuity deteriorates

Engineering Contradiction:

Core Design Contradiction:
Area of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The invention moves the scanning signal line driving circuits from the peripheral frame regions to the inner display region, utilizing the vertical space above the pixel electrodes. This dimensional relocation allows the circuits to overlap with the pixel electrodes in the vertical direction while maintaining horizontal continuity of the display region, thereby eliminating visible frame regions between multiple display units.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The scanning signal line driving circuits are nested within the display region by positioning them to overlap with the pixel electrodes in the vertical direction. The circuits are arranged in the vertical space above the pixel electrodes, effectively nesting the circuit layer within the display area and eliminating the need for separate peripheral frame regions.
