Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in reducing power consumption while maintaining effective color display capabilities.
Innovation Solution
The display panel design includes a specific arrangement of data lines and light emitting elements, where connection lines overlap data lines on a plane, and light emitting elements partially overlap pixel circuits, allowing for efficient delivery of color-specific data signals, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection lines are routed to connect light emitting elements to pixel circuits, then electrical connectivity is achieved, but power consumption increases due to signal transmission losses
Solution Approach 1:
The patent introduces data lines as intermediary conductors that carry color-specific data signals from data driving circuits to pixel circuits. These data lines act as mediators that efficiently transmit signals without direct connection between light emitting elements and pixel circuits, reducing transmission losses and power consumption while maintaining reliable electrical connectivity through the intermediary data line infrastructure.
2Adaptability or versatility
If multiple data lines are used to deliver color-specific signals, then color display capability is enhanced, but device complexity increases
Solution Approach 1:
The patent segments the data transmission system into multiple dedicated data lines (first data line, second data line, third data line, fourth data line), each responsible for delivering data signals for specific color channels (red, green, blue, white). This segmentation enables precise color control and enhanced display capability while managing complexity through functional specialization of each data line rather than using a single complex multi-channel transmission system.
Solution Approach 2:
Each data line is designed to serve multiple purposes: delivering data signals for specific color channels, overlapping with connection lines to establish electrical connectivity, and working in coordination with corresponding pixel circuits and light emitting elements. This multi-functionality reduces the need for separate dedicated structures for each function, thereby managing device complexity while maintaining versatile color display capability.
3Area of stationary object
If light emitting elements are positioned to overlap pixel circuits, then area efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent resolves the positioning challenge by transitioning from a two-dimensional planar arrangement to a three-dimensional stacked architecture. Light emitting elements are positioned in an upper layer that overlaps pixel circuits in a lower layer, with connection lines and data lines routed through intermediate layers. This vertical stacking enables area efficiency by utilizing the third dimension (height) rather than requiring precise lateral alignment, thereby reducing manufacturing precision requirements while maintaining compact area utilization.
