Segmented OLED Display Screen for Full-Area Camera Exposure

Solution Overview

Problem

Existing OLED display screens face issues with reduced display area, mechanical strength, and dust/waterproofing due to camera holes, which compromise the display effect and structural integrity.

Innovation Solution

A segmented OLED display screen design with separate regions, one region containing driving elements and the other without, utilizing transparent materials and electrodes to maintain transparency and functionality without additional driving elements, allowing light emission and avoiding structural holes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a hole is formed in the display screen for the camera, then the camera can be exposed, but the display area is reduced

Engineering Contradiction:

Improvecamera exposureVSAvoiddisplay area

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The display screen is divided into a first region and a second region. The first region contains driving elements and is not transparent, while the second region contains no driving elements and is transparent. This segmentation allows the camera to be positioned in the transparent second region without forming a hole, thus maintaining the full display area while enabling camera exposure.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If a hole is formed in the display screen for the camera, then the camera can be exposed, but the mechanical strength is reduced

Engineering Contradiction:

Improvecamera exposureVSAvoidmechanical strength

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The display screen is divided into a first region and a second region. The first region contains driving elements and is not transparent, while the second region contains no driving elements and is transparent. This segmentation allows the camera to be positioned in the transparent second region without forming a hole, thus maintaining the full display area while enabling camera exposure.

3Adaptability or versatility

If a hole is formed in the display screen for the camera, then the camera can be exposed, but dust proofing and water proofing are compromised

Engineering Contradiction:

Improvecamera exposureVSAvoiddust and water infiltration

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The display screen is divided into a first region and a second region. The first region contains driving elements and is not transparent, while the second region contains no driving elements and is transparent. This segmentation allows the camera to be positioned in the transparent second region without forming a hole, thus maintaining the full display area while enabling camera exposure.

AI summary

An organic light-emitting diode, OLED, display screen and an electronic device are provided. The OLED display screen includes, in a first direction, a first region (101) and a second region (102). A first film layer (103) in the first region (101) of the display screen is provided with one or more driving elements (1031), and the first film layer (103) in the second region (102) of the display screen is provided with no driving element. One or more first light-emitting elements (1041) arranged in the first region (101) and one or more second light-emitting elements (1042) arranged in the second region (102) are driven by the one or more driving elements (1031) in the first region (101).
