Display Device Dynamic Image Processor Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with optical disk playback functionality require unnecessary power consumption and a waiting period due to the activation of the image processor for all image signals, regardless of their source, as the image processor must process signals from both external interfaces and DVD modules.
Innovation Solution
A display device with an image information extracting module, an image processor, a display unit, and a control unit that allows the display unit to receive image signals directly from the extracting module without activating the image processor unless a picture quality activation command is received, enabling the image processor to be deactivated for non-processed signals and activated for processed signals as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the image processor is activated for all image signals regardless of source, then picture quality processing is ensured, but power consumption increases and waiting period occurs
Solution Approach 1:
The image processor is designed to dynamically switch between active and inactive states based on the signal source. When a DVD module signal is detected, the processor remains inactive unless picture quality mode is selected. When an external interface signal is detected, the processor is activated. This dynamic state change resolves the contradiction by making picture quality processing conditional rather than constant.
Solution Approach 2:
The system changes the operational parameter of the image processor from a fixed 'always on' state to a variable state that depends on the signal source and user selection. The control unit modifies the processor's activation status based on detected conditions, allowing the system to adapt power consumption and processing levels to actual needs rather than maintaining a static high-power state.
2Measurement precision
If the image processor is activated for all image signals, then picture quality processing is ensured, but startup time increases due to waiting period
Solution Approach 1:
The image processor transitions from a static always-active state to a dynamic state that activates only when needed. The control unit detects the signal source and selectively activates the processor, eliminating the fixed waiting period that occurred in the conventional approach where the processor always had to initialize regardless of whether processing was actually required.
Solution Approach 2:
The control unit performs preliminary detection of the signal source before activating the image processor. This preliminary action allows the system to determine in advance whether picture quality processing is needed, thereby avoiding unnecessary activation delays and startup waiting periods when processing is not required.
3Use of energy by moving object
If the display unit receives image signals directly from the DVD module, then power consumption is reduced, but picture quality processing capability is lost
Solution Approach 1:
The system dynamically routes image signals based on user selection and signal source. When power saving mode is selected or no picture quality enhancement is needed, signals are routed directly from the DVD module to the display unit. When picture quality mode is selected, the control unit activates the image processor and routes signals through it. This dynamic routing resolves the contradiction by making the processing path selectable rather than fixed.
Solution Approach 2:
The control unit serves multiple functions by selectively controlling both the activation state of the image processor and the routing path of image signals. This multi-functionality allows the system to handle both direct signal transmission (for power saving) and processed signal transmission (for quality enhancement) through a single control mechanism, resolving the contradiction between power consumption and picture quality.

AI summary
A display device with playback functionality includes: an image information extracting module for extracting image information from a storage medium, and processing the image information so as to generate and output a first setting image signal conforming with a specific format; an image processor for receiving the first setting image signal and performing picture quality processing so as to generate and output a second setting image signal conforming with the specific format; a display unit capable of receiving and displaying one of the first and second setting image signals conforming with the specific format; and a control unit for performing control such that the display unit receives one of the first and second setting image signals when a command is received, and the other of the first and second setting image signals when the command is not received.
