Passive Display Border Reflector for Seamless Bezel Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturing tolerances in display panel modules result in a visible gap region between the opaque border and active area, disrupting the immersive user experience when the opaque border is not black, as lighter images reveal the gap as a black frame.
Innovation Solution
Incorporating a reflective display area in the inactive area that reflects ambient light in a desired color, matching or complementing the opaque border, using a color filter and reflector to adjust the perceived color of the gap region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the opaque border is made wide enough to cover the entire inactive area, then the border can effectively hide routing circuitry, but manufacturing tolerances create a visible gap region that disrupts the seamless bezel effect
Solution Approach 1:
The patent applies color filtering to the gap region by placing a color filter layer in the inactive area that matches the color of the opaque border. This causes the gap region to reflect ambient light in the same color as the border, making the gap invisible to users and maintaining the seamless bezel effect despite manufacturing tolerances
Solution Approach 2:
The patent changes the optical parameters of the gap region by introducing a reflector and color filter that control how ambient light is reflected. By adjusting the reflectivity and color characteristics of the gap region to match the opaque border, the patent eliminates the visual discontinuity caused by manufacturing variations
2Adaptability or versatility
If the opaque border is black to appear seamless, then the gap region is hidden, but the design flexibility for different border colors is lost
Solution Approach 1:
The patent enables any opaque border color (not just black) by using a color filter layer in the gap region that matches the border color. This allows the device to offer various border colors while maintaining the seamless appearance, as the gap region will always reflect the same color as the border regardless of which color is selected
Solution Approach 2:
The patent creates a universal solution that works for any opaque border color by using adjustable color filters and reflectors. The same structural approach (color filter + reflector in the gap region) can be applied regardless of whether the border is black, white, blue, or any other color, providing design flexibility without compromising the seamless bezel effect
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
Provides a seamless bezel effect by matching the gap region's color with the opaque border, enhancing the immersive user experience regardless of the opaque border's color.
Implementation Method 1
a reflective display area and a bezel area. The reflective display area is disposed between the active area and the bezel area... The reflective display area includes a color filter that filters ambient light and a reflector that reflects filtered light
Implementation Method 2
The reflective display area includes a color filter that filters ambient light and a reflector that reflects filtered light

AI summary
This document describes techniques and systems for displays with passive display areas. The displays include a display panel module (308) that defines an active area (AA) with an array of light-emitting pixels (312) configured to emit light (30) and an inactive area (IA), free of light-emitting pixels. The inactive area includes a reflective display area including at least one color filter (336) and at least one reflector (340). In aspects, the reflective display area includes at least one diffuser (442).
