Light Guide Members Extend Into Non-Active Area To Reduce Bezel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display apparatuses have limited display area due to the presence of a significant bezel area, which is the non-display area that houses the driver components and does not contribute to image display.
Innovation Solution
Incorporating light guide members on the boundary pixels that extend into the non-active area and are disposed on non-pixels, which are designed to scatter and reflect light, allowing the display of images across the non-active area, effectively reducing the bezel area by guiding light from boundary pixels to non-pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a non-display area (bezel) is provided around the display area to house driver components, then the driver can be properly disposed and controlled, but the effective display area is reduced and the bezel area becomes significant
Solution Approach 1:
The patent merges the display area and non-display area by extending light guide members from boundary pixels into the non-active area, causing light to be guided to non-pixels in the non-active area. This combines the functional display area with the structural non-active area, effectively eliminating the visual boundary between them and reducing the perceived bezel area.
Solution Approach 2:
The patent utilizes the third dimension (depth/vertical layering) by employing light guide members that extend vertically from the pixel layer into the non-active area. This dimensional transition allows light to travel from the active area through the light guide members to illuminate non-pixels in the non-active area, effectively using vertical space to expand the display area without increasing the horizontal footprint.
2Area of stationary object
If the non-active area is reduced to enlarge the display area, then the effective display area increases, but the driver components may not have sufficient space for proper disposal and operation
Solution Approach 1:
The light guide members act as intermediary elements that bridge the boundary between the active display area and the non-active area. These intermediaries enable light to be transported from boundary pixels to non-pixels in the non-active area, allowing the non-active area to contribute to light display while still accommodating driver components, thus resolving the conflict between maximizing display area and maintaining driver component functionality.
3Area of stationary object
If light guide members are extended into the non-active area and disposed on non-pixels, then light is guided from boundary pixels to non-pixels enabling image display on the non-active area, but the device structure becomes more complex
Solution Approach 1:
The light guide members serve multiple functions: they guide light from boundary pixels to non-pixels in the non-active area, enable image display across the entire panel including the non-active area, and maintain the structural integrity of the display device. This multi-functionality justifies the added structural complexity by delivering significant benefits in terms of expanded effective display area and reduced bezel appearance.
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
This solution enables a substantial display of images on the non-active area, thereby reducing the bezel area and increasing the effective display area, potentially achieving a 'zero bezel' configuration.
Implementation Method 1
a plurality of light guide members disposed on boundary pixels of the pixels in the active area and which extends into the non-active area and is disposed on the non-pixels in the non-active area. The boundary pixels are adjacent to a boundary between the active area and the non-active area. The light guide members guide light exiting from the boundary pixels to the non-pixels.
Implementation Method 2
a plurality of non-pixels disposed in a non-active area adjacent to the active area and which include light-scattering particles
Implementation Method 3
a plurality of reflective layers disposed under the non-pixels
