Solution Overview

Problem

Existing tiled display devices often exhibit visible seams between tiles, detracting from the visual experience and impairing the perception of seamless 3D images.

Innovation Solution

A tiled display device with a first unit pixel displaying a background image at a first depth and a second unit pixel displaying a target image at a different second depth, with the seam area minimized by adjusting pixel distances and depths to reduce visibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple display devices are assembled to form a tiled display, then the display area is increased, but visible seams appear between tiles

Engineering Contradiction:
Improvedisplay areaVSAvoidvisible seams
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by differentiating the depth of display content based on spatial location. Pixels adjacent to seam areas render background images at a first depth, while pixels away from seams render target images at a second depth. This local differentiation in depth rendering creates a visual transition that masks the physical seam, making it less perceptible to viewers while maintaining the expanded display area.

Inventive Principle:
Principle #3Local quality

2Ease of manufacture

If pixels are arranged in a grid pattern, then the manufacturing process is simplified, but seam visibility increases

Engineering Contradiction:
Improvepixel arrangementVSAvoidseam visibility
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent changes the depth parameter of displayed images based on pixel location relative to seams. By adjusting the depth parameter dynamically - using a first depth for pixels near seams and a second depth for pixels away from seams - the system maintains the simple grid arrangement for ease of manufacture while creating a depth-based visual mask that reduces seam visibility.

Inventive Principle:
Principle #35Parameter changes

AI summary

A tiled display device includes a display panel having a plurality of pixels, a seam area disposed between first, second, third, and fourth groups of the pixels, an optical panel disposed on the display panel, and a controller configured output a background image to the pixels that are spaced apart from the seam area having a first depth and output a target image to the pixels that are adjacent the seam area having a second depth different from the first depth.
