Solution Overview

Problem

Conventional display devices with integrated camera functions face challenges in optimizing the placement of optical members, leading to reduced display area efficiency and potential light interference between the display and camera areas.

Innovation Solution

The implementation of a display device design featuring a substrate with a light transmission area surrounded by a display area, utilizing first and second light blocking members with specific openings to prevent light interference and maintain the optical member's functionality, thereby enhancing display quality by concealing the peripheral area of the optical member.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an optical member is integrated within the display area, then camera functionality is achieved, but the display area is reduced and light interference occurs

Engineering Contradiction:

Improvecamera functionalityVSAvoiddisplay area

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The display device is divided into distinct functional zones: a display area for image output and a light transmission area for optical member placement. The boundary area with light blocking members creates clear segmentation between these zones, allowing camera functionality without compromising the display area integrity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The optical member is positioned in a different spatial dimension (light transmission area) rather than within the display area plane. This vertical/dimensional separation allows both camera functionality and full display area to coexist without interference.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If an optical member is integrated within the display area, then camera functionality is achieved, but light interference between display and camera areas occurs

Engineering Contradiction:

Improvecamera functionalityVSAvoidlight interference

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

Light blocking members are introduced as intermediary elements between the display area and the optical member. These members block stray light from the display area, preventing light interference with the optical member while allowing the camera functionality to operate correctly.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The harmful light interference is extracted and blocked by introducing light blocking members in the boundary area. This removes the adverse effect from the system while preserving the beneficial camera functionality.

Inventive Principle:

Principle #2Taking out (Extraction)

3Device complexity

If the peripheral area of the optical member is visible, then structural simplicity is maintained, but display quality is degraded

Engineering Contradiction:

Improvestructural simplicityVSAvoiddisplay quality

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The light blocking members are selectively positioned in the boundary area to block only the peripheral area of the optical member that would be visible during display. This local intervention improves display quality without requiring complete structural redesign, maintaining a balance between simplicity and precision.

Inventive Principle:

Principle #3Local quality
