Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices lack the capability to simultaneously display different types of information, such as movies, advertisements, and guidance messages, on a single device with varying display areas and light transmittance characteristics.
Innovation Solution
A display device with multiple display areas, including a light emitting area and a transmitting area with higher light transmittance, is designed, featuring a driving circuit that allows for independent image display in each area, enabling flexible bending and folding configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single display area is used, then the device structure is simple, but the capability to simultaneously display different types of information is limited
Solution Approach 1:
The display panel is divided into multiple independent display areas (first display area, second display area, third display area) that can simultaneously display different types of information such as movies, advertisements, and guidance messages. Each display area has its own scanning lines and pixel structures, enabling independent control and simultaneous operation without interfering with each other.
Solution Approach 2:
The display device integrates multiple display areas with different functions within a single panel structure. The first display area displays full-color images, the second display area displays monochrome images, and the third display area provides transparent display functionality. This multi-functional design allows one device to replace multiple separate display devices.
2Illumination intensity
If a light emitting area is used, then image display capability is achieved, but light transmittance is reduced
Solution Approach 1:
The display panel implements different light transmittance characteristics in different areas: the first display area uses light-emitting pixels with lower transmittance for image display, while the third display area uses transparent pixels with higher transmittance for see-through functionality. This local differentiation allows each area to optimize its performance for its specific function without compromising the other.
Solution Approach 2:
Each display area is segmented into light emitting areas and transmitting areas at the pixel level. The light emitting areas contain light-emitting elements for image display, while the transmitting areas allow light to pass through for transparent display functionality. This segmentation enables simultaneous achievement of image display and light transmittance within the same physical structure.
3Adaptability or versatility
If multiple display areas with different shapes are used, then flexible information display is enabled, but manufacturing complexity increases
Solution Approach 1:
Different display areas are assigned different shapes and functions: the first display area has a first shape for main content display, the second display area has a second shape for additional information, and the third display area has a third shape for transparent display. Each area's pixel structures and scanning lines are configured according to its specific shape requirements, allowing flexible information display while maintaining manufacturability through localized design.
4Reliability
If transmitting area with higher light transmittance is used, then light transmittance is improved, but image display capability is reduced
Solution Approach 1:
Each pixel in the third display area is segmented into a light emitting area and a transmitting area. The light emitting area contains the light-emitting element for displaying images, while the transmitting area allows light to pass through for transparent display. This segmentation enables the same pixel structure to provide both image display and light transmittance functions.
Solution Approach 2:
The third display area implements a universal pixel structure that can perform both image display and transparent display functions. By incorporating both light emitting and transmitting areas within the same pixel structure, the display panel achieves multi-functionality without requiring separate hardware components.

AI summary
A display device includes a display panel including a first display area having a first shape and a second display area having a second shape, and a first driving circuit which drives the display panel to display an image in at least one of the first display area and the second display area, where the first display area includes a first sub-area and a second sub-area, and the second sub-area includes a light emitting area and a transmitting area adjacent to the light emitting area and having a higher light transmittance than the light emitting area.
