Wireless Display Compression Control for Light-Blocking States
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless display systems consume excessive power and suffer from reduced wireless communication quality due to uniform compression of image data regardless of the light blocking state or ambient brightness of the display.
Innovation Solution
A wireless transmitting device adjusts the compression rate of image data based on the light blocking state and ambient brightness of the display, using a processor to determine optimal compression rates for different light blocking states and brightness levels, and employs a light blocking film to manage light transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If uniform compression rate is used for image data regardless of light blocking state, then device complexity is reduced, but power consumption increases and wireless communication quality deteriorates
Solution Approach 1:
The compression rate is made dynamic and adjustable based on the light blocking state of the display. The system transitions from static uniform compression to dynamic adaptive compression, where the compression rate changes in response to real-time light blocking conditions, allowing optimization of power consumption while maintaining image quality where needed.
Solution Approach 2:
The system changes the compression rate parameter based on the light blocking state. When the light blocking state changes (e.g., from fully transparent to fully light-blocking), the compression rate is adjusted accordingly. This parameter adaptation allows the system to reduce power consumption by using lower compression rates when the display is light-blocking, as the viewer cannot see the content anyway.

The system transitions from static uniform compression to dynamic adaptive compression, where the compression rate changes in response to real-time light blocking conditions, allowing optimization of power consumption while maintaining image quality where needed.
Solution Approach 2:
The system incorporates feedback from the light blocking state detection to adjust the compression rate. By continuously monitoring the light blocking state and using this feedback information, the system can adapt the compression rate to maintain optimal wireless communication quality. When the display is in a light-blocking state, the system reduces compression to prevent quality degradation, ensuring reliable transmission.
3Use of energy by moving object
If high compression rate is used for image data, then power consumption is reduced, but image quality deteriorates when light blocking state requires high definition
Solution Approach 1:
The system changes the compression rate parameter based on the light blocking state. When the light blocking state changes (e.g., from fully transparent to fully light-blocking), the compression rate is adjusted accordingly. This parameter adaptation allows the system to reduce power consumption by using lower compression rates when the display is light-blocking, as the viewer cannot see the content anyway.
Solution Approach 2:
The system applies different compression rates to different situations based on the light blocking state. Instead of using a single uniform compression rate, the system locally adapts the compression level to the specific conditions. When the display is in a light-blocking state, it uses lower compression to maintain image quality, while using higher compression when the display is transparent to save power.
