Display Panel Via Hole Mirror Light Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies face challenges in maximizing the screen-to-body ratio due to the occupation of cameras and sensors, which limits the ability to achieve a narrow bezel design.
Innovation Solution
A display panel design incorporating a housing with obliquely positioned plane mirrors that redirect light from a via hole to a sensor's camera opening, allowing for a reduced via hole size and minimized sensor area occupation, thereby increasing the display ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a via hole is defined on the front surface for the front camera, then the front camera can capture light from the front surface, but the via hole occupies large space on the display area, reducing the display ratio
Solution Approach 1:
The patent introduces a via hole that extends from the front surface through the housing to the back surface, creating a three-dimensional light transmission path. This vertical dimensionality allows light to reach the front camera sensor without occupying additional lateral display area, effectively resolving the contradiction between camera functionality and display ratio.
Solution Approach 2:
The via hole structure nests multiple functional elements within a single vertical pathway: the light transmission channel, the front camera sensor positioned at the back surface, and the light shielding region arrangement. This nesting consolidates what would otherwise require separate lateral spaces into a compact vertical arrangement, preserving display area while maintaining camera function.
2Area of stationary object
If the via hole is reduced in size to minimize sensor occupation, then the display ratio increases, but the light transmission capability for the front camera may be compromised
Solution Approach 1:
The patent applies light shielding regions selectively in specific locations around the via hole on the front surface, rather than uniformly across the entire housing. The light shielding regions are positioned to guide light into the via hole while allowing maximum light transmission through the via hole itself. This localized approach optimizes light transmission efficiency without requiring a large via hole diameter, thus maintaining small sensor occupation and high display ratio.
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 design effectively reduces sensor occupation on the display area, enhancing the screen-to-body ratio and enabling a more significant narrow bezel implementation.
Implementation Method 1
The first plane mirror is disposed in the housing and is disposed under the via hole obliquely... Light from the via hole is reflected by the first plane mirror
Implementation Method 2
The second plane mirror is disposed in the housing and is disposed under the camera opening of the first sensor obliquely... enters the camera opening of the first sensor after being reflected by the second plane mirror
