Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If channel conversion is performed with preset output setting information, then the display device can quickly switch channels, but the user experiences uncomfortable viewing due to sudden changes in screen brightness and audio output strength
Solution Approach 1:
The patent applies dynamics by making the output settings adjustable and adaptive rather than fixed. The processor dynamically modifies screen brightness and audio output strength based on sensed environmental conditions (illumination and sound levels) when channel conversion occurs, allowing the system to switch channels quickly while simultaneously adapting the output to maintain viewing comfort.
Solution Approach 2:
The patent changes the parameters of screen brightness and audio output strength based on environmental sensing data. When channel conversion is detected, the processor adjusts these parameters according to the sensed illumination and sound levels, transforming the fixed preset output settings into adaptive variable settings that respond to environmental conditions.
2Illumination intensity
If screen brightness is increased in dark environment, then the content becomes more visible, but user eyes experience fatigue due to sudden brightness change
Solution Approach 1:
The patent applies preliminary action by sensing the environmental illumination level before channel conversion occurs and using this information to pre-adjust the screen brightness of the new channel. The processor detects the current illumination conditions and prepares appropriate brightness settings in advance, so when channel conversion happens, the brightness transition is already optimized to prevent eye fatigue.
Solution Approach 2:
The patent uses feedback from the illumination sensor to continuously monitor environmental light conditions and adjust screen brightness accordingly. The sensor provides feedback about the surrounding illumination level, and the processor uses this feedback to modify the output brightness, creating a closed-loop system that adapts to environmental changes and prevents harmful brightness transitions.
3Power
If audio output strength is increased in quiet environment, then the content audio becomes audible, but user experiences discomfort due to sudden volume change
Solution Approach 1:
The patent applies preliminary action by sensing the environmental sound level before channel conversion and using this information to pre-adjust the audio output strength. The processor detects the current ambient sound conditions and prepares appropriate volume settings in advance, so when channel conversion occurs, the audio transition is already optimized to prevent listening discomfort.
Solution Approach 2:
The patent uses feedback from the sound sensor to continuously monitor environmental noise levels and adjust audio output strength accordingly. The sensor provides feedback about the surrounding sound conditions, and the processor uses this feedback to modify the audio output, creating a closed-loop system that adapts to environmental changes and prevents harmful volume transitions.

AI summary
A display device and a control method therefor are disclosed. According to the disclosure, the display device comprises: a sensor for sensing the surrounding environmental state; an inputter for receiving a user command for content conversion; an outputter for outputting content corresponding to the user command; and a processor for controlling the outputter such that screen brightness and/or audio output strength of second content corresponding to the user command is changed and outputted, when the user command is inputted, on the basis of the sensed surrounding environmental state and/or output information of currently outputted first content. Therefore, the display device can variously output an output of content image and/or audio according to the surrounding environmental state.
