Solution Overview
Problem
Conventional data processing devices continuously transmit the same line data to data driving devices, leading to increased power consumption in display devices due to ongoing data communication.
Innovation Solution
Implementing a data processing device with a transmission circuit that transmits image data in units of line data and deactivates the transmission circuit if a predetermined number of identical line data are consecutively arranged, along with a control signal to deactivate the reception circuit in the data driving device, thereby reducing unnecessary data communication.

Engineering Contradiction Analysis
1Productivity
If continuous data communication is performed between the data processing device and the data driving device, then the display device can continuously update the display content, but the power consumption for data communication increases
Solution Approach 1:
The patent implements periodic action by deactivating the transmission circuit when identical line data is detected consecutively for a predetermined number of times, and reactivating it when different line data is detected. This creates an on-demand communication pattern that maintains display update capability while reducing unnecessary continuous communication, thereby lowering power consumption during periods of repeated display content.
2Use of energy by moving object
If the transmission circuit is deactivated to reduce power consumption, then unnecessary data transmission is minimized, but the display device cannot update when line data changes
Solution Approach 1:
The patent employs feedback mechanisms where the data processing device continuously monitors incoming line data for changes. When a change is detected (different line data after consecutive identical data), the system automatically reactivates the transmission circuit. This feedback loop ensures the display remains responsive to content changes while maintaining power savings during static display periods.
Solution Approach 2:
The transmission circuit transitions between active and inactive states dynamically based on the content being displayed. The system adapts its communication behavior to the actual display requirements, being active only when necessary for updates and inactive when the display content remains unchanged, thus optimizing both power consumption and update responsiveness.
