Solution Overview
Problem
Heating system control devices face challenges in reducing power consumption while maintaining accurate temperature control and user interface clarity, particularly due to the need for continuous room temperature monitoring and display, which limits the effectiveness of power-saving methods like switching to low-power modes.
Innovation Solution
The display device is divided into high-resolution graphics and low-resolution simple areas, with the low-resolution area remaining operational in power-saving mode and indicating the mode through minimal symbols, and the high-resolution area being switched off to conserve battery life, while ensuring all control and comfort functions remain available.

Engineering Contradiction Analysis
1Loss of information
If the display is operated continuously with high resolution to provide clear user interface and accurate temperature monitoring, then user clarity and control accuracy are improved, but power consumption increases
Solution Approach 1:
The display is divided into multiple display areas with different resolution requirements. Critical information areas (such as temperature display) maintain high resolution for clarity, while less critical areas use lower resolution to reduce power consumption. This segmentation allows the system to optimize the balance between information clarity and energy usage.
Solution Approach 2:
Different display areas are assigned different quality levels (resolution) based on their functional importance. Areas requiring precise temperature readings maintain high resolution, while status indicator areas use lower resolution. This local differentiation ensures that power is consumed only where necessary for maintaining user clarity.
2Duration of action of moving object
If the display is switched to power-saving mode to extend battery life, then power consumption is reduced, but user interface clarity and control accuracy may be compromised
Solution Approach 1:
The display alternates between high-resolution mode during active user interaction and low-resolution power-saving mode during idle periods. The system periodically switches between these states based on detected user activity, ensuring that full clarity is available when needed while extending battery life during non-use periods.
Solution Approach 2:
The display resolution is dynamically adjusted based on system state and user interaction. When the device detects user presence or interaction, it switches to high-resolution mode for clear interface display. When idle or in power-saving mode, it transitions to lower resolution, dynamically optimizing the balance between battery life and interface clarity.

AI summary
The indicator has a display (1) with a display region (A) serving as a graphic region with a higher resolution and disconnected in a current saving operating condition. A display region (B) serves as a simple display region with a smaller resolution, and is durably operated in the current saving operating condition. The region (B) is directly connected with a micro controller (2) by conductors (4) and directly controlled by the conductors. The region (A) is controlled by an LCD controller (3), which is disconnected in the current saving operating condition or connected in a standby mode.
