Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing display technologies, incident light has a relatively large reflectivity when entering a camera, which interferes with imaging quality and reduces the amount of admitted light, complicating the manufacturing process and user experience.
Innovation Solution
An optical assembly comprising a light-transmissive cover plate, an optical transparent adhesive, a polarizer, a display panel, and an antireflection coating, where the polarizer and display panel have through-holes corresponding to the camera, and the antireflection coating is strategically positioned to reduce reflectivity, including multiple layers on various surfaces to minimize reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If only a polarizer and an optical clear adhesive in an area above a camera are removed, then process complexity is reduced, but incident light has a relatively large reflectivity when entering the camera
Solution Approach 1:
The patent applies anti-reflection coating technology to convert the harmful reflective effect into a beneficial low-reflection state. By coating the cover plate and display panel surfaces with anti-reflection layers, the reflectivity of incident light entering the camera is significantly reduced, thereby improving imaging quality while maintaining the simplified structure of removing only the polarizer and adhesive in the camera area.
Solution Approach 2:
The patent changes the optical parameters of the surface by introducing anti-reflection coatings with specific refractive indices and thicknesses. This parameter modification reduces the reflectivity at the air-glass interface, allowing more incident light to enter the camera directly without undergoing multiple reflections, thus resolving the contradiction between simplified manufacturing and reduced reflectivity.
2Ease of operation
If multiple reflections occur at a cover plate and a display panel, then incident light can enter the camera, but the amount of admitted light is reduced and imaging quality is interfered with
Solution Approach 1:
The anti-reflection coatings convert the harmful multiple reflection phenomenon into a beneficial direct transmission state. By reducing the reflectivity at each interface through anti-reflection coating, the light is able to enter the camera directly with minimal reflection losses, thereby increasing the amount of admitted light and improving imaging quality.
Solution Approach 2:
The patent modifies the optical parameters of the cover plate and display panel surfaces by applying anti-reflection coatings with optimized thickness and refractive index. This parameter change reduces the reflectivity coefficient at the interfaces, enabling more light to be transmitted directly into the camera without undergoing multiple reflections, thus resolving the contradiction between light entry capability and light quantity.
