Display Panel Optical Areas for Narrow Bezel Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in achieving a narrow bezel design without compromising image quality, particularly when integrating optical electronic devices like cameras and sensors into the display panel.
Innovation Solution
The implementation of a display device structure with optical areas that allow light transmission for optical electronic devices, such as cameras and sensors, while maintaining high image quality, involves arranging subpixels and signal lines in a way that minimizes the bezel size by positioning these devices under the display panel and optimizing the transmittance of specific areas.

Engineering Contradiction Analysis
1Length of stationary object
If optical electronic devices are integrated into the display panel to reduce bezel size, then the bezel width is reduced, but the image quality deteriorates due to light transmission areas
Solution Approach 1:
The patent applies local quality by creating optical areas with different transmittance characteristics in specific regions of the display panel. The first optical area has a first transmittance while the second optical area has a second transmittance, allowing each region to be optimized for its specific function (camera or sensor) while maintaining overall image quality. This localized differentiation enables the bezel to be narrowed without compromising the visual display quality in non-optical regions.
Solution Approach 2:
The display panel is segmented into multiple functional areas: normal areas for image display, first optical areas for camera integration, and second optical areas for sensor integration. This segmentation allows each area to be independently optimized - the optical areas enable device integration while the normal areas maintain image quality, thus resolving the contradiction between narrow bezel and high image quality.
2Adaptability or versatility
If optical areas with high transmittance are created for optical electronic devices, then device integration is enabled, but the image display performance deteriorates
Solution Approach 1:
Different optical areas are assigned different transmittance values according to their specific functional requirements. The first optical area has a first transmittance optimized for camera operation, while the second optical area has a second transmittance optimized for sensor operation. This localized optimization ensures that each optical area provides sufficient light transmission for its designated device while minimizing impact on overall image display performance.
Solution Approach 2:
The display panel is divided into normal areas that maintain high image display performance and optical areas that provide necessary light transmission. By segmenting the panel in this way, the patent enables versatile device integration without requiring the entire display to compromise its image quality, thus resolving the contradiction between adaptability and image display performance.
