Photochromic Mold Frame Minimizing Display Shadow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems face a shadowing issue due to the visibility of internal components when bezel widths are reduced, leading to diminished picture quality and user experience.
Innovation Solution
A mold frame with a color-changing material, specifically photochromic pigment, is integrated into the inner portion, which changes from a first color (black) to a second color (grey) when exposed to light, minimizing the shadow around the display by absorbing light wavelengths and causing a photochemical reaction, and a reflector is used to further reduce visibility of internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If bezel width is reduced to increase display area, then display area is improved, but shadow visibility increases
Solution Approach 1:
The mold frame incorporates a color-changing material that transitions from a first color (causing shadow) to a second color (minimizing shadow) when exposed to light from the display, directly addressing the shadow visibility issue while maintaining the reduced bezel design
Solution Approach 2:
The patent changes the optical parameter (color/reflectivity) of the mold frame material dynamically in response to display operation, transforming it from a shadow-causing state to a shadow-minimizing state when the display is active
2Object-affected harmful factors
If mold frame uses light-absorbing material to reduce shadow, then shadow visibility is reduced, but picture quality is improved
Solution Approach 1:
The mold frame's optical properties are made dynamic rather than static, allowing it to adapt its appearance based on display operation state, thereby achieving shadow reduction without compromising picture quality during active use
Solution Approach 2:
By implementing color-changing material that responds to display light, the system achieves both shadow reduction and picture quality maintenance, as the material transitions to a state that minimizes visual interference with the displayed image
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 minimizes the shadow around the display, enhancing picture quality and user experience by camouflaging internal components within the field of view, maintaining the original appearance when not in use.
Implementation Method 1
the inner portion including a color-changing material causing the inner portion to change from a first color to a second color... the color-changing material is comprised of a photochromic pigment... absorbing, by the photochromic pigment, one or more wavelengths of light emitted by a light source of the display; and causing, by the photochromic pigment, a photochemical reaction within the mold frame

AI summary
Systems and methods are disclosed for a mold frame for an information handling system that may include an outer portion configured to couple the mold frame to an exterior portion of a cover bottom of the display; a middle portion including an adhesive portion configured to couple the mold frame to a panel of the display; and an inner portion configured to contact an interior portion of the cover bottom, the inner portion including a color-changing material causing the inner portion to change from a first color to a second color, the first color causing the shadow around the display, the second color causing the shadow around the display to minimize.
