Adaptive Display Dimming for Longer Service Life
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Displays used in retail, industry, logistics, and laboratory environments experience significant reductions in effective lifetime due to prolonged operation and high brightness, despite being designed for long hours of use, which is exacerbated by ambient conditions and regulatory requirements, leading to premature degradation.
Innovation Solution
Implement an active and automated display dimming method that adjusts brightness parameters based on initial settings and monitors aging indicators, such as brightness, temperature, and operating time, to maintain consistent display brightness and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display is operated with high brightness for long hours to meet regulatory requirements and provide clear information, then the information clarity and regulatory compliance are improved, but the display lifetime is significantly reduced
Solution Approach 1:
The patent applies dynamics by making the display brightness adjustable and adaptive rather than fixed. The system dynamically adjusts brightness based on ambient light conditions and usage patterns, allowing the display to operate at lower brightness when full brightness is not needed, thereby extending lifetime while maintaining information clarity when required
Solution Approach 2:
The patent changes the brightness parameter adaptively based on measured ambient light conditions and usage duration. By monitoring ambient light levels and adjusting the display brightness parameter accordingly, the system maintains sufficient information clarity while reducing brightness-induced aging when high brightness is not necessary for visibility
2Duration of action of stationary object
If the display brightness is reduced to extend lifetime, then the display lifetime is improved, but the information clarity and regulatory compliance may be compromised
Solution Approach 1:
The patent implements feedback by continuously measuring ambient light conditions and usage parameters, then using this information to adjust display brightness. The system monitors whether reduced brightness maintains sufficient information clarity and regulatory compliance, adjusting accordingly to balance lifetime extension with information visibility requirements
Solution Approach 2:
The patent applies preliminary action by proactively adjusting brightness before significant aging occurs. The system monitors usage duration and ambient conditions to predict when brightness reduction would be beneficial, extending lifetime preventively while maintaining information clarity through adaptive adjustment rather than waiting for degradation to occur
3Duration of action of stationary object
If automated brightness adjustment is implemented to extend lifetime, then the display lifetime and energy efficiency are improved, but the device complexity increases
Solution Approach 1:
The patent applies self-service by enabling the display system to automatically monitor its own usage patterns and ambient conditions, then adjust its own brightness without external intervention. This automated self-adjustment extends lifetime and improves energy efficiency while minimizing the need for complex external control systems or manual user configuration

AI summary
The invention relates to the field of displays (monitors, terminals) used in retail, industry, logistics, transportation and laboratory, in particular displays for retail weighing devices. A method for increasing the lifetime of such displays is provided. The method includes setting a brightness dimming parameter of the display to an initial value that is below a possible maximum value, determining whether a parameter that is characteristic for an aging of the display reached a threshold value, and increasing the brightness dimming parameter if the parameter that is characteristic for an aging of the display reached the threshold value. Further provided are a corresponding display, computer program, and retail, industry, logistics, transportation and laboratory devices, in particular a corresponding retail weighing device.
