Display Standby Color Control via Potential Difference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices in standby mode display only a black image, which does not match the environment and consume more power as the device size increases, making them aesthetically poor and inefficient.
Innovation Solution
A display device with a display panel, gate lines, data lines, and a common line, where a gate switching unit connects gate lines, a data switching unit groups data lines, and a standby mode driving unit generates potential differences between data lines and the common line using different voltage signals to display various colors with minimal power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a display device displays a black image in standby mode, then the device structure is simple, but the aesthetics are poor and the wall becomes black
Solution Approach 1:
The patent applies color changes by displaying different colored standby screens (e.g., blue, green, yellow) instead of a fixed black image. The display device can switch between multiple colors to match different environmental settings, transforming the standby display from a static black screen to a dynamically adaptable colored display that enhances aesthetic integration with the surrounding environment.
2Adaptability or versatility
If a display device displays a predetermined image repeatedly for a long time, then the aesthetics improve, but the power consumption increases
Solution Approach 1:
The patent implements periodic action by cyclically switching between multiple standby screen colors rather than continuously displaying a single static image. This periodic color switching maintains aesthetic appeal and visual interest while reducing overall power consumption compared to continuously displaying a single predetermined image, as the display can enter lower-power states between color transitions.
Solution Approach 2:
The patent applies dynamics by transitioning from a static black standby display to a dynamic multi-color standby display system. The display device can dynamically switch between different colors and patterns, making the standby mode more visually engaging and adaptable to different environments while managing power consumption through controlled dynamic operation.
3Area of moving object
If the size of the display device is increased, then the display area expands, but the power consumption increases
Solution Approach 1:
The patent applies partial action by implementing a standby mode that uses reduced power consumption techniques specifically for large display areas. Instead of fully activating all display elements at maximum brightness, the system uses partial activation with lower power consumption modes, such as displaying simplified color patterns or reducing refresh rates during standby, thereby maintaining the visual presence of large displays while significantly reducing their power consumption.
