Solution Overview

Problem

Electronic devices with integrated liquid crystal panels and cameras face challenges in capturing clear images due to the interference of light from the display area affecting the camera's incident light control area, leading to suboptimal image quality.

Innovation Solution

The implementation of a liquid crystal panel with an incident light control area featuring a first and second annular light-shielding portion, which controls the amount of light reaching the camera, ensuring optimal image capture by blocking unnecessary light and adjusting the light transmissive area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the camera and liquid crystal panel are integrated on the same surface, then the device achieves compact design and multifunctionality, but light from the display area interferes with the camera's incident light control area, degrading image quality

Engineering Contradiction:

Improvedevice surface area utilizationVSAvoidlight interference from display area

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The liquid crystal panel is divided into distinct functional areas: a display area for showing images and an incident light control area for camera operation. This segmentation allows each area to perform its specific function without interference, as the incident light control area is optimized to receive light for the camera while the display area manages light for visualization purposes.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the liquid crystal panel are assigned different optical properties. The incident light control area has specific light transmission characteristics optimized for camera input, while the display area has different characteristics optimized for user viewing. This local differentiation ensures that light management in one area does not negatively impact the other.

Inventive Principle:

Principle #3Local quality

2Ease of manufacture

If the incident light control area uses a simple structure, then manufacturing is easier and cost is reduced, but image clarity and quality are compromised due to inadequate light management

Engineering Contradiction:

Improveincident light control area fabricationVSAvoidimage clarity

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent extracts and isolates the light management function into a dedicated incident light control area with specific light-shielding portions. By separating this function from the general display area, the system achieves precise light control for the camera without requiring complex modifications to the entire panel structure, thus maintaining manufacturing simplicity while improving image quality.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The incident light control area acts as an intermediary between the external environment and the camera sensor. It includes light-shielding portions that selectively block unwanted light paths while allowing necessary light to reach the camera, thereby mediating light transmission to achieve clear images without requiring direct complex optical components at the camera level.

Inventive Principle:

Principle #24Intermediary (Mediator)
