Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with integrated optical electronic devices, such as cameras and sensors, face challenges in maintaining image quality and design aesthetics due to the need for a wider bezel or notches, which restricts the front design and can lead to unexpected deterioration in image quality.
Innovation Solution
A display panel design featuring a light transmittable optical area and a unique arrangement of subpixel circuit units in the optical bezel area, allowing for enhanced light transmittance without exposing optical electronic devices on the front surface, thus preventing an increase in the optical bezel area and maintaining designed shape and image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If optical electronic devices are exposed on the front surface of the display device, then light reception is easy, but the bezel area increases and design freedom is restricted
Solution Approach 1:
The patent moves the optical electronic device from the front surface (2D plane) to the rear side of the display device, utilizing the third dimension (depth) to resolve the conflict between light reception and bezel area. The light transmission structure allows light to pass through the display panel from front to back, enabling the optical device to receive light without being exposed on the front surface.
Solution Approach 2:
The patent introduces a light transmission structure as an intermediary between the front surface and the optical electronic device on the rear side. This intermediary component (light transmission structure with transmittance ≥80%) enables light to reach the optical device while maintaining the front surface integrity and minimizing bezel area.
2Ease of operation
If optical electronic devices are installed with wider bezel or notches, then light reception is improved, but the front design is restricted
Solution Approach 1:
The invention relocates the optical electronic device to the rear side of the display panel, utilizing the depth dimension to enable light reception without compromising front surface design. This allows full design freedom on the front surface while maintaining effective light reception through the light transmission structure.
Solution Approach 2:
The patent extracts the optical electronic device from the front surface design, placing it on the rear side. This separation allows the front surface to maintain its design integrity without notches or widened bezels, while the extracted optical device still receives light through the transmission structure.
3Ease of manufacture
If the display panel uses uniform subpixel circuit units, then manufacturing is simple, but light transmittance in the optical area is reduced
Solution Approach 1:
The patent applies different subpixel circuit unit configurations in different regions: the optical area uses units with higher light transmittance (optimized for light passage), while the non-optical area uses standard units. This local differentiation maintains overall manufacturing simplicity while enhancing light transmittance where needed.
Solution Approach 2:
The display panel is segmented into an optical area and a non-optical area, with different subpixel circuit unit designs applied to each segment. This segmentation allows the optical area to be optimized for light transmission while the rest of the panel maintains standard manufacturing processes.
