Spliced Display Light Bar Slit Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In spliced screens, the frame area outside the display area creates slits that affect visual experience and reduce the screen-to-body ratio, as existing technologies are limited by technical restrictions in minimizing this frame area.
Innovation Solution
A spliced screen design incorporating a light bar with light-emitting units that cover the area between unit screens, enhancing structural stability and visually eliminating or reducing slits by synchronously transmitting light across the display areas, thereby increasing the screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If unit screens are spliced together to form a display, then the display area increases, but slits are formed by frame gaps which affect visual experience and reduce screen-to-body ratio
Solution Approach 1:
The patent converts the harmful frame area into a beneficial light-emitting region. The light bar is disposed in the frame area and emits light to cover the slit regions, transforming the previously harmful frame gaps into useful light-emitting zones that enhance display continuity and visual experience while maintaining the increased display area from spliced screens
2Object-affected harmful factors
If frame area is reduced to minimize slits, then visual experience improves, but structural stability and connection between unit screens deteriorates
Solution Approach 1:
The light bar serves multiple functions simultaneously: it provides structural support for connecting unit screens, emits light to cover slit regions and improve visual experience, and can be integrated with the frame structure. This multi-functionality allows the frame area to maintain structural stability while being utilized for light emission to reduce visual impact of slits
3Object-affected harmful factors
If light bar is added to cover slit areas, then visual experience and screen-to-body ratio improve, but device complexity increases
Solution Approach 1:
The patent merges the light bar with the frame structure of the unit screens. The light bar is disposed in the frame area and can be integrated with existing structural elements, combining the functions of framing and light emission into a single unified structure, thereby improving visual experience without proportionally increasing device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces the visual impact of slits and enhances the structural stability of spliced screens by securely connecting unit screens, improving the overall display effect and user experience through increased screen-to-body ratio.
Implementation Method 1
The light bar includes a cover area, abutting on an eminent surface of the unit screens, a plurality of light-emitting units, and a defined area

AI summary
A spliced screen and a display device are provided. A light-emitting unit is arranged and covers the area between display areas of a two unit screens. When the display area of the unit screens normally functions, a plurality of light-emitting units on a light bar can be transmitted and displayed synchronously, cover an area which cannot be shown between the display areas of the two unit screens, and further, weaken or eliminate a slit visually. In this way, the display screen of each of the unit screens is coherently connected to the display screen, and the visual screen-to-body ratio increases as well.
