Display Panel Pixel Layout to Cut RGB Data Voltage Toggling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels with alternating red and blue light emitting areas experience high power consumption due to toggling of red and blue data voltages, and additional data lines are required to prevent this, increasing dead space and power consumption further.
Innovation Solution
A display panel design where pixel circuits are connected to data lines in a manner that allows one data line to output a single color voltage without toggling, eliminating the need for additional data lines and reducing power consumption by minimizing dead space through cross connections between pixel circuits and light emitting areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If red and blue data voltages are applied alternately to data lines in a display panel with alternating red and blue light emitting areas, then the display function is achieved, but power consumption increases due to voltage toggling
Solution Approach 1:
The patent segments the data lines into color-specific lines (red data lines and blue data lines) and assigns each line to transmit only one color's data voltage continuously. This segmentation eliminates the need to toggle voltages on shared data lines, thereby reducing power consumption while maintaining display functionality.
2Use of energy by moving object
If additional data lines are added to prevent toggling of red and blue data voltages, then power consumption is reduced, but dead space increases and power consumption for driving additional lines occurs
Solution Approach 1:
The patent merges the functions of red and blue data transmission into shared data lines by using color conversion technology. Each pixel circuit can generate both red and blue data voltages from a single color's data line through color conversion, eliminating the need for separate red and blue data lines and reducing dead space while maintaining low power consumption.
3Reliability
If additional data lines are added to prevent toggling, then voltage toggling is prevented, but device complexity increases
Solution Approach 1:
The patent makes each data line universal by enabling it to transmit data for both red and blue colors through color conversion at the pixel circuit level. A single data line can serve multiple color channels, reducing the overall number of data lines needed and simplifying the data line structure while ensuring voltage stability through continuous transmission.
