Solution Overview
Problem
Existing display devices in communication venues, such as conference rooms, lack efficient automated monitoring systems to detect malfunctions, which can lead to unscheduled maintenance and disruptions in communication processes.
Innovation Solution
An automated monitoring system that uses a photo sensor to capture light data from the display device and a processor to analyze this data against an expected sequence, detecting errors and recording any malfunctions, allowing for remote or local servicing of the equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated monitoring is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The display device performs self-diagnosis by using its own processor to control test image display and coordinate photo sensor measurements. The device monitors itself without requiring external monitoring equipment, thereby improving reliability while avoiding additional system complexity.
Solution Approach 2:
The processor serves multiple functions: it controls test image display, processes photo sensor signals, determines malfunctions, and records error data. This multi-functionality eliminates the need for separate dedicated monitoring components, improving reliability without increasing device complexity.
2Productivity
If manual checks are performed, then device complexity is reduced, but productivity deteriorates
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated optical measurement system. The photo sensor automatically captures light emissions from the display, and the processor automatically analyzes the data to detect malfunctions, significantly improving maintenance efficiency without requiring complex manual procedures.
Solution Approach 2:
The system continuously monitors display performance by comparing actual photo sensor measurements against expected values. When deviations indicate malfunctions, the system automatically records error data and triggers alerts, enabling proactive maintenance before communication disruptions occur.

Data Source
AI summary
An apparatus that automatically monitors a display device includes a photo sensor configured to receive light from a display screen of the display device. The photo sensor provides signals representing detected light levels to a processor. The processor is coupled to the display device and is configured to cause the display device to present a test sequence including a plurality of images on the display screen. The processor is configured to capture data from the photo sensor during the presentation of the test sequence and to compare the captured data to an expected sequence corresponding to the test sequence displayed by a well-functioning display. The processor is further configured to report any mismatch between the captured data and the expected sequence as a possible malfunction of the display device.
