Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices face challenges in maximizing the display area while minimizing the bezel area, which affects the overall image quality and user experience.
Innovation Solution
The proposed solution involves a display device with a dual display area structure, where a controller processes image signals to optimize the rendering of image data across both areas, utilizing a combination of normal and base pixel parts with specific light emitting elements and signal processing techniques to enhance image quality and reduce the perceivable bezel area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display area is enlarged to reduce the bezel area, then the display area is increased, but the image quality may deteriorate due to the use of fewer light emitting elements per pixel
Solution Approach 1:
The display panel is divided into a first display area with normal pixel parts (higher image quality) and a second display area with base pixel parts (lower image quality). This segmentation allows the overall display area to be enlarged while maintaining high image quality in the primary viewing area, thus resolving the contradiction between enlarging display area and maintaining image quality.
Solution Approach 2:
Different regions of the display panel are assigned different pixel structures and image quality characteristics. The first display area uses normal pixel parts with more light emitting elements for high image quality, while the second display area uses base pixel parts with fewer light emitting elements. This local quality differentiation enables the display area to be enlarged without compromising the image quality in the primary display region.
2Area of moving object
If the number of light emitting elements per pixel is reduced to enlarge the display area, then the display area is increased, but the device complexity increases due to multiple pixel types and signal processing
Solution Approach 1:
The controller is designed to handle multiple types of pixel parts (normal pixel parts and base pixel parts) and their corresponding image signals through a unified rendering process. The controller can process first image signals for the first display area and second image signals for the second display area, generating appropriate image data for each pixel type. This multi-functionality allows the system to manage the complexity of multiple pixel types without requiring separate processing systems, thus enabling display area enlargement while controlling device complexity.
3Area of moving object
If different pixel parts with different numbers of light emitting elements are used, then the display area is enlarged, but the manufacturing precision requires higher control over image signal rendering
Solution Approach 1:
The controller performs preliminary rendering of image signals before they are sent to the display panel. It receives first image signals and second image signals, renders them to generate first image data and second image data respectively, and ensures that the image data is appropriately adjusted for the different pixel types. This preliminary action ensures that the image quality is maintained despite the different numbers of light emitting elements in normal and base pixel parts, thus enabling display area enlargement while maintaining manufacturing precision.

AI summary
A display panel includes a first display area and a second display area. A plurality of base pixel parts are disposed in the second display area, and each base pixel part includes “k” first color light emitting elements. A controller receives image signals, and the image signals include first image signals corresponding to the first display area and second image signals corresponding to the second display area. The second image signals are divided into a plurality of base signal parts respectively corresponding to the plurality of base pixel parts, and each base signal part includes “m*n” first color image signals. The controller generates color image data by rendering “p” color image signals of “m*n” color image signals included in a corresponding base signal part and “(m*n)−p” referenced image signals included in a referenced signal part adjacent to the corresponding base signal part.
