Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses for outdoor or public use, such as advertisements or guidance systems, lack efficient methods for remotely monitoring and maintaining the image display conditions of liquid crystal panels, requiring manual site visits or external camera setups.
Innovation Solution
A display apparatus with a reflective panel opposite to the liquid crystal panel, which captures images using light reflected by the panel, allowing for internal image capture and remote monitoring of display conditions, enabling operators to maintain the system without physical presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual site visits or external camera setups are used to monitor image display conditions, then monitoring can be performed, but operational complexity and maintenance time increase
Solution Approach 1:
The patent merges the image capture function with the display panel by integrating image capture devices directly into the liquid crystal panel structure. The capture devices are positioned to utilize the same light path as the display function, allowing the display apparatus to simultaneously perform display and self-diagnosis functions through a unified structure, thereby reducing operational complexity while maintaining monitoring reliability
Solution Approach 2:
The liquid crystal panel is designed to serve multiple functions: it acts as both the display medium for showing images and as the housing for image capture devices that monitor display conditions. This multi-functional design eliminates the need for separate external monitoring systems, reducing device complexity while ensuring reliable monitoring of image display conditions
2Measurement precision
If operators physically visit installation sites to check display conditions, then direct observation is possible, but time consumption and operational efficiency decrease
Solution Approach 1:
The display apparatus performs self-diagnosis by incorporating image capture devices within the liquid crystal panel that automatically monitor display conditions. The system captures images of the displayed content and analyzes them to detect dead pixels, display unevenness, and other anomalies without requiring external intervention, thereby achieving precise measurement while eliminating time loss associated with manual site visits
Solution Approach 2:
The integrated image capture devices provide continuous feedback on display conditions by capturing and analyzing images of the displayed content. This real-time feedback mechanism enables automatic detection of display abnormalities, allowing operators to remotely identify and address issues without physically visiting the installation site, thus maintaining high detection accuracy while significantly reducing maintenance time
3Ease of operation
If separate external cameras are installed for monitoring, then image capture is possible, but device complexity and installation difficulty increase
Solution Approach 1:
The image capture devices are nested within the liquid crystal panel structure itself, with capture devices positioned in the liquid crystal layer or on the backlight unit. This nested configuration allows the monitoring system to be integrated within the existing display apparatus without requiring separate external camera installations, thereby achieving ease of remote operation while minimizing device complexity

AI summary
A display apparatus which comprises a liquid crystal panel and displays a predetermined image comprises: a reflective panel which is arranged opposite to the liquid crystal panel and reflects light emitted from the liquid crystal panel; and image capture devices which are located in the liquid crystal panel and capture an image on a display surface of the liquid crystal panel using light reflected by the reflective panel. An image display condition of the liquid crystal panel of the display apparatus is captured by the display apparatus itself.
