Solution Overview
Problem
Existing display devices face challenges in reducing power consumption while maintaining display quality, particularly in managing the operating frequencies and initialization voltages of different display areas.
Innovation Solution
A display device is designed with a display panel divided into multiple areas operating at different frequencies, where the anode initialization voltage is adjusted based on the operating mode and frequency, using a voltage generator and driving controller to manage these voltages and frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the operating frequency is reduced to lower power consumption, then energy efficiency improves, but display quality deteriorates due to luminance differences
Solution Approach 1:
The display panel is divided into multiple display areas, each capable of operating at different frequencies. This allows different regions to have different operating characteristics optimized for their specific requirements, enabling some areas to run at lower frequencies for power savings while others maintain higher frequencies for quality
Solution Approach 2:
The anode initialization voltage is dynamically adjusted based on the operating frequency of each display area. When operating frequency changes, the initialization voltage is modified to compensate for potential luminance differences, ensuring consistent display quality across areas with different operating frequencies
2Use of energy by moving object
If different display areas operate at different frequencies, then power consumption is reduced, but voltage management complexity increases
Solution Approach 1:
The voltage generator is configured to dynamically adjust the anode initialization voltage based on the operating mode and frequency of each display area. This dynamic voltage adjustment capability allows the system to adapt to different operating conditions without requiring complex manual intervention or multiple fixed voltage sources

AI summary
Disclosed is a display device including a display panel including a plurality of pixels and a voltage generator providing an anode initialization voltage to the pixels. The display panel is divided into a first display area operating at a first operating frequency and a second display area operating at a second operating frequency. While pixels, which correspond to the first display area, from among the plurality of pixels are driven, the anode initialization voltage has a first voltage level. While pixels in the second display area from among the plurality of pixels are driven, the anode initialization voltage has a second voltage level different from the first voltage level.
