Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with integrated cameras or face recognition systems face a reduction in screen-to-body ratio due to the incorporation of these features, which compromises the display area and user experience.
Innovation Solution
A display device design featuring a first pixel region for image display and a second pixel region for camera or face recognition, with varying spacer densities and configurations to maintain image quality and support additional functionalities while optimizing screen real estate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera or face recognition function is integrated on the display side, then the display device gains additional functionality, but part of the display area is sacrificed resulting in reduced screen-to-body ratio
Solution Approach 1:
The display area is segmented into a first pixel region with higher resolution for main display and a second pixel region with lower resolution for camera/face recognition functions. This segmentation allows both high-quality display and additional functionality to coexist by allocating different resolution levels to different regions, thereby maintaining overall screen-to-body ratio while enabling dual purposes.
2Adaptability or versatility
If the display area is reduced to accommodate camera or face recognition features, then additional functionality is achieved, but the screen-to-body ratio deteriorates
Solution Approach 1:
Different resolution qualities are applied to different regions of the display. The first pixel region maintains high resolution for primary display content, while the second pixel region uses lower resolution sufficient for camera or face recognition functions. This local quality differentiation allows the device to achieve additional functionality without sacrificing the overall screen-to-body ratio, as the lower resolution region occupies minimal space.
3Measurement precision
If higher resolution is maintained in the first pixel region, then image quality is improved, but the complexity of the display structure increases due to varying spacer densities
Solution Approach 1:
The spacer density parameter is changed across different regions of the display. The first pixel region uses a first spacer density corresponding to high resolution requirements, while the second pixel region uses a second spacer density corresponding to lower resolution requirements. This parameter change allows the display to maintain high image quality in the primary region while reducing structural complexity in the secondary region, as fewer or less densely arranged spacers are needed for lower resolution pixels.

AI summary
A display device includes a first pixel region and a second pixel region adjacent to the first pixel region. The display device includes: a first substrate; a second substrate opposite to the first substrate; and a plurality of spacers disposed between the first substrate and the second substrate. Herein, a first portion of the plurality of spacers are disposed in the first pixel region, a second portion of the plurality of spacers are disposed in the second pixel region, a disposition density of the second portion of the plurality of spacers in the second pixel region is different from a disposition density of the first portion of the plurality of spacers in the first pixel region.
