Display System Dynamic Bandwidth Adjustment Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for high-resolution displays leads to higher power consumption due to increased data transmission between hosts and display devices, which existing technologies have not effectively addressed.
Innovation Solution
A display system that adjusts the bandwidth of transmitting lines based on image signal information and uses a subset of lines when necessary, employing a host controller to generate driving signals that control the activation state of transmitting lines, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution display is implemented, then display quality is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamic bandwidth adjustment by allowing the transmitting lines to operate at different bandwidths depending on the actual image signal requirements. The system can dynamically switch between high bandwidth modes (for high-resolution content) and low bandwidth modes (for lower-resolution or static content), thereby maintaining display quality when needed while reducing power consumption during normal operation.
Solution Approach 2:
The patent changes the operational parameters of the transmitting lines by adjusting bandwidth and activation states based on image signal characteristics. The host controller analyzes image content and modifies transmission parameters (bandwidth, number of active lines) accordingly, enabling the system to adapt power consumption to actual display requirements rather than operating at fixed high-performance settings.
2Speed
If bandwidth of transmitting lines is increased, then data transmission speed is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the bandwidth of transmitting lines based on actual data transmission needs. The host controller monitors image signal characteristics and activates high-bandwidth modes only when high-speed transmission is necessary, otherwise operating at lower bandwidths to conserve power while maintaining adequate transmission speed.
Solution Approach 2:
The patent modifies transmission parameters by changing bandwidth settings and line activation states according to image content analysis. This allows the system to optimize the trade-off between transmission speed and power consumption by using full bandwidth only when high-resolution or high-frame-rate content requires it.
3Productivity
If all transmitting lines are activated, then data transmission capacity is improved, but power consumption increases
Solution Approach 1:
The patent extracts and activates only the necessary number of transmitting lines based on image signal requirements. Instead of keeping all lines continuously active, the host controller determines the minimum number of lines needed for current content and activates only those, leaving others in a low-power state while maintaining sufficient transmission capacity.
Solution Approach 2:
The system applies partial action by activating a subset of transmitting lines rather than all lines simultaneously. The host controller analyzes image content and activates only the portion of transmission channels necessary for current display requirements, reducing overall power consumption while maintaining adequate data transmission capacity.

AI summary
A display system includes a plurality of transmitting lines configured to transmit a plurality of image signals and a display device configured to display an image based on the image signals applied thereto through the transmitting lines. At least one transmitting line of the transmitting lines is further configured to transmit the image signals at a bandwidth that is adjusted according to the information of the image signals.
