Borderless Display via Light Refraction in Cover Plate Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Viewers experience a black border in the frame area of display devices due to the non-display regions, which affects the visual experience.
Innovation Solution
A display device with a light-transmitting cover plate featuring a first light-transmitting part for the display area and a second light-transmitting part for the frame area, where the outer surface of the second light-transmitting part includes an optical part that refracts light to match the direction of the light transmitted through the first light-transmitting part, eliminating the black border.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a frame area is provided to arrange wires for the display panel, then the structural integrity and wiring capability are improved, but viewers see a black border in the frame area which deteriorates the visual experience
Solution Approach 1:
A light-transmitting cover plate is introduced as an intermediary component between the display panel and the external environment. This cover plate includes a second light-transmitting part corresponding to the frame area, which allows light from the display panel to pass through the frame area and reach viewers, thereby eliminating the black border effect while preserving the wiring functionality in the frame area.
Solution Approach 2:
The solution transitions from a two-dimensional view of the frame area (where wires are arranged) to a three-dimensional optical path consideration. By making the cover plate translucent and positioning it in the third dimension, light can pass through the frame area from the display panel, converting the frame area from a non-visible region to a light-transmitting region without compromising the wiring arrangement.
2Object-affected harmful factors
If the light-transmitting cover plate is made fully transparent, then the borderless display effect is improved, but the structural protection and wiring arrangement capability deteriorate
Solution Approach 1:
The light-transmitting cover plate is designed with different regions having different properties: a first light-transmitting part corresponding to the display area and a second light-transmitting part corresponding to the frame area. This local differentiation allows the frame area to transmit light for borderless display while maintaining the structural integrity and wiring arrangement capabilities in the same region.
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 borderless display by ensuring the light direction through the frame area is consistent with the display area, enhancing the viewer's experience by removing the black border.
Implementation Method 1
the outer surface of the second light-transmitting part is provided with an optical part used to change the exit direction of the light transmitted through the second light-transmitting part
