Optical Adhesive Layer Positioning in Display Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reflection-type display screens face reduced optical effect due to insufficient ambient light, as they rely on reflection rather than transmission of light, leading to decreased light usage and eye fatigue.
Innovation Solution
A display module comprising a panel, a light guiding component with equally spaced light guiding dots, and an optical adhesive layer positioned on the light guiding plate, where the adhesive layer's thickness matches the distance from the light guiding dots to the plate, allowing efficient light transmission and preventing air refraction index interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a reflection-type display screen is used to reduce LED influence and eye fatigue, then eye fatigue is reduced, but the optical effect is reduced when ambient light is insufficient
Solution Approach 1:
The light guiding plate is segmented with multiple light guiding dots that redirect light at different angles, creating multiple light paths to enhance display visibility while maintaining reflection-type eye comfort benefits
Solution Approach 2:
The optical adhesive layer is positioned specifically at the light guiding dots rather than uniformly across the entire display, concentrating optical enhancement where light redirection occurs most effectively
2Loss of energy
If the optical adhesive layer is positioned close to the light guiding component, then light transmission efficiency improves, but air refraction index interference increases
Solution Approach 1:
The optical adhesive layer acts as an intermediary substance between the light guiding dots and the panel, eliminating air gaps that cause refraction index interference while maintaining close proximity for efficient light transmission
Solution Approach 2:
The refractive index parameter is optimized by selecting adhesive material with appropriate optical properties that match the light guiding component, minimizing refraction losses at the interface

Function Achieved in This Case
Enhances light transmission efficiency and optical effect by ensuring the light guiding dots are effectively connected to the panel, reducing eye fatigue and improving display performance even in low ambient light conditions.
Implementation Method 1
the optical adhesive layer is transparent and has a side pasted on and connected to the panel... the top of the light guiding dots touches the panel

AI summary
A display module includes a panel, a light guiding component, and an optical adhesive layer. The light guiding component includes a light guiding plate having a side facing the panel, and light guiding dots, equally spaced on the side of the light guiding plate. The optical adhesive layer positioned on the light guiding plate is transparent and has a side pasted on and connected to the panel and the side of the optical adhesive layer is comparatively far away from the light guiding component. This could prevent the optical adhesive from covering the light guiding layer of the light guiding component or prevent the refractive index of the flowing air layer from affecting the light transmission efficiency of the light guiding layer. Thus, the light transmission efficiency of the light guiding plate is raised and the display performance and the optical effect of the display module are raised.
