1Use of energy by moving object
If a single power voltage is applied to all light-emitting elements, then the device structure is simple, but power consumption cannot be optimized
Solution Approach 1:
The display device is divided into multiple light-emitting areas (first light-emitting area and second light-emitting area), each with its own dedicated power voltage line. This segmentation allows independent power management for different regions, enabling optimization of power consumption by applying appropriate voltage levels to each area based on its specific requirements.
Solution Approach 2:
Different power voltage levels are applied to different light-emitting areas according to their specific needs. The first power voltage line provides a first power voltage to the first light-emitting area while the second power voltage line provides a second power voltage to the second light-emitting area, allowing local optimization of power efficiency rather than uniform power distribution.
