Borderless Display Panel Light Guide Refraction Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels with borders limit the size of the picture displayed and the amount of information shown, and attempts to eliminate borders by direct attachment to a backlight result in a weak bond between the panel and the backlight.
Innovation Solution
A display panel design featuring light guides on the outer surface of a second substrate, which refract light from the edges of the display region towards the border region, allowing for a narrow or borderless display without compromising the bond with the backlight, including first and second light guides, a solar cell, and a planarization layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the border region is reduced or eliminated to improve display area, then the display area increases, but the bond between the display panel and backlight becomes insufficient
Solution Approach 1:
The patent introduces light guides with refraction surfaces that redirect light from the display region edges into the border region, effectively utilizing the border area for light guidance rather than treating it as wasted space. This dimensional approach to light redirection allows the border to serve dual purposes: maintaining structural bonding area while enabling optical functionality that reduces visible border width.
Solution Approach 2:
The light guides act as intermediary elements between the display region and the border region. They receive light from the display edges and redirect it into the border area, serving as a mediating structure that allows the border to maintain its structural role while simultaneously reducing its visual prominence through optical manipulation.
2Shape
If light guides are added to guide light towards the border region, then the border visibility is reduced, but the device structure becomes more complex
Solution Approach 1:
The light guides serve multiple functions: they structurally support the display panel, provide optical guidance to redirect light into the border region, and contribute to the overall structural integrity. By making the light guides multi-functional, the patent reduces the need for separate components, thereby managing complexity while achieving borderless display effects.
Solution Approach 2:
The patent merges the light guiding function with the structural support function by integrating the light guides into the existing panel structure. Rather than adding separate light guiding components, the design combines optical functionality with structural elements, reducing overall 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
Enables a narrow or borderless display while maintaining a strong bond between the display panel and the backlight, enhancing visual experience and power supply durability through efficient light guidance and solar energy harvesting.
Implementation Method 1
the light guides include first light guides, which are provided at edges of the display region so as to guide light emitted from the edges of the display region towards an upside of at least a part of the border region

AI summary
A display panel according to the present invention includes a first substrate and a second substrate which are arranged opposite to each other, and an outer surface of the second substrate includes a display region and a border region surrounding the display region. Wherein, the display panel further includes a plurality of light guides provided on the outer surface of the second substrate, and the light guides include first light guides, which are provided at edges of the display region so as to guide light emitted from the edges of the display region towards an upside of at least a part of the border region. Since the first light guides guide light emitted from the edges of the display region towards an upside of at least a part of the border region, display with a narrow border or even display without a border can be achieved.
