Solution Overview

Problem

Existing electronic devices with display panels positioned over cameras face challenges in optimizing light transmission to the camera while minimizing diffraction and diffusion caused by the display panel's structure.

Innovation Solution

The electronic device incorporates a display panel with a first region disposed on the camera, featuring an emission layer with uniformly spaced pixels, an encapsulation layer, and an opaque metal layer below the emission layer. The opaque metal layer includes a plurality of openings with a specific periphery design, comprising first portions with a first radius of curvature and second portions with a shorter second radius of curvature, positioned between the first portions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a display panel is positioned over a camera to achieve a larger display area, then the display area is increased, but light diffraction and diffusion occur that degrade image quality

Engineering Contradiction:

Improvedisplay areaVSAvoidlight diffraction and diffusion

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The display panel is divided into a first region positioned over the camera and a second region surrounding the first region. The emission layer is selectively disposed only in the first region, creating segmented light emission zones that prevent diffraction and diffusion affecting the camera while maintaining display functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the display panel are assigned different functional properties. The first region has an emission layer for light emission, while the second region lacks an emission layer to prevent harmful light effects. This local differentiation allows the display to achieve large area while protecting camera image quality.

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If an opaque metal layer with openings is introduced to reduce diffraction, then image quality improves, but the device structure becomes more complex

Engineering Contradiction:

Improvelight diffraction reductionVSAvoidlayer structure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The emission layer is extracted and disposed only in the first region above the camera, removing the source of diffraction and diffusion harmful effects from the areas surrounding the camera. This extraction eliminates the need for additional opaque metal layers with complex opening patterns.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of adding an opaque metal layer with openings to block harmful light, the invention inverts the approach by strategically placing the emission layer only where needed (first region) and omitting it from other areas (second region). This negative space approach achieves the same goal with fewer layers.

Inventive Principle:

Principle #13The other way round (Inversion)
