Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in expanding their display area while accommodating electronic components, as existing designs often compromise on image quality and resolution due to the integration of components like cameras within the display panel.
Innovation Solution
The display device incorporates a main display area and separate component areas with auxiliary sub-pixels and cameras, using an opaque layer with a hole for light transmission, and a driver to synthesize image signals from multiple camera angles, replacing deterioration data with pixel data from other camera signals to enhance image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If electronic components are integrated within the display panel to expand display area, then display area is expanded, but image quality and resolution deteriorate due to component interference
Solution Approach 1:
The display panel is divided into distinct regions: a main display area for high-quality image display and component areas for housing electronic components. This segmentation allows each region to be optimized independently, maintaining image quality in the main display area while accommodating components in designated areas without interference.
Solution Approach 2:
An opaque layer with a hole corresponding to the transmission area is introduced as an intermediary structure. This layer blocks light in component areas while maintaining light transmission in the transmission area, preventing component interference with the display while allowing necessary light passage for sensor operations.
2Adaptability or versatility
If cameras are disposed under the substrate to capture images, then functionality is enhanced, but light diffraction occurs affecting image quality
Solution Approach 1:
The opaque layer acts as an intermediary between the cameras and the display area. By positioning the opaque layer with a hole above the cameras and aligning it with the transmission area, it guides and controls light transmission, preventing light diffraction while enabling camera functionality through the designated transmission area.
Solution Approach 2:
The opaque layer introduces local quality variation: it is opaque in component areas to block light and prevent diffraction, but has a hole in the transmission area to allow light transmission. This localized differentiation enables cameras to function without causing light diffraction issues across the entire panel.
3Manufacturing precision
If multiple cameras are used to synthesize image signals, then image quality is improved, but device complexity increases
Solution Approach 1:
Multiple cameras are merged into a unified imaging system with a common opaque layer and transmission area structure. The driver synthesizes image signals from multiple cameras to improve image quality, while the shared structural components (substrate, opaque layer, transmission area) reduce overall device complexity compared to having separate imaging systems.
