Engineering Contradiction Analysis
1Use of energy by moving object
If conventional image signal processing is used in display devices, then image quality can be maintained, but power consumption cannot be effectively reduced
Solution Approach 1:
The image signal processing is divided into separate processing paths for different color channels (first green image signal and second green image signal). By segmenting the processing of green channel data and using selection circuits to choose between different processed versions, the system reduces redundant computations and lowers power consumption while maintaining image quality.
2Reliability
If full image signal processing is performed for all color channels, then image quality is maintained, but device complexity and power consumption increase
Solution Approach 1:
The patent merges the processing paths for the first green image signal and second green image signal by using a selection circuit that can switch between different processed versions. This merging approach allows the system to maintain image quality through multiple processing options while reducing overall device complexity by sharing common processing resources and selection logic.

AI summary
Disclosed is a display device which includes a driving controller, a data driving circuit, a selection circuit, and a display panel. The driving controller performs rendering processing for red, green, and blue input image signals to generate a red, a first green, a blue, and a second green image signal, and converts the red, first green, blue, and second green image signals into red image data, first green image data, blue image data, and second green image data. The data driving circuit converts the red, first green, blue, and second green image data into the red, first green, blue, and second green image signals. The selection circuit selectively outputs the red, first green, blue, and second green image signals.
