Window Color Layer for Display Light Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in managing image brightness and external light interference, particularly in areas where input icons are displayed, leading to inconsistent user experience and energy inefficiency.
Innovation Solution
A display device design incorporating a window member with a color layer that includes photo-blocking and photo-transmitting particles, where the color layer is divided into a shield layer and a semi-transmitting layer to control image brightness and external light, with a photo-curing adhesive layer connecting the touch panel and window member, allowing for controlled light transmission and absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a color layer is added to the window member to block external light, then external light interference is reduced, but the brightness of the transmitted image decreases
Solution Approach 1:
The color layer is divided into a first portion overlapping the border of the base member and a second portion overlapping the display member. The first portion contains dye or pigment for blocking external light, while the second portion contains photo-blocking and photo-transmitting particles for selective light control, allowing different regions to have different optical properties tailored to their specific functions.
Solution Approach 2:
The color layer is formed as a composite material containing both photo-blocking particles (black color) and photo-transmitting particles (transparent) dispersed in a resin. This composite structure enables simultaneous light blocking and light transmission functions within the same layer, resolving the contradiction between external light rejection and image brightness maintenance.
2Loss of energy
If photo-blocking particles are added to reduce image brightness in non-essential areas, then energy efficiency is improved, but the complexity of the color layer increases
Solution Approach 1:
The color layer is segmented into functionally distinct portions: a first portion for external light blocking at the border, and a second portion for selective light transmission over the display member. This segmentation allows each region to be optimized for its specific purpose, improving energy efficiency in non-essential areas while maintaining the overall structural integrity of the window member.
Solution Approach 2:
The optical parameters of the color layer are changed by controlling the concentration and distribution of photo-blocking and photo-transmitting particles in different portions. This allows optimization of light transmission characteristics to improve energy efficiency without requiring fundamentally different materials or structures.
3Object-affected harmful factors
If a shield layer and semi-transmitting layer are created to control light transmission, then light interference management is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The shield layer and semi-transmitting layer are merged into a single integrated color layer structure. The first portion of the color layer functions as the shield layer for external light blocking, while the second portion functions as the semi-transmitting layer for image transmission. This merging simplifies the manufacturing process by eliminating the need for separate layer fabrication and assembly, while still achieving the desired light interference management.

AI summary
A display device includes a display member that displays an image, and a window member arranged on an upper surface of the display member. The window member includes a base member and a color layer, and the color layer is arranged on a lower surface of the base member and partially overlaps the display member. A part of the window member overlaps the display member, and the part of the window member receives a portion of the image from the display member as a received image and transmits the portion of the image therethrough as a transmitted image.
