Solution Overview
Problem
Existing display devices face challenges in efficiently driving multiple display panels with larger screens while maintaining compact size, reduced thickness, and flexible folding capabilities, often requiring multiple driving chips that increase production costs and power consumption.
Innovation Solution
A display device incorporating a first and second display panel driven by a single driving circuit, allowing simultaneous or individual operation, with flexible folding and bending features, and supporting different use modes by supplying data voltage and control signals at varying frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple driving chips are used to drive multiple display panels, then each panel can be driven independently and reliably, but the device size increases, production cost increases, and power consumption increases
Solution Approach 1:
The patent combines multiple driving functions into a single driving chip. The driving chip is configured to drive both the first display panel and the second display panel, integrating what would traditionally require separate driving chips. This merging reduces the overall device volume while maintaining the capability to independently control multiple panels through a unified control architecture.
Solution Approach 2:
The driving chip is designed with universal functionality to drive multiple types of display panels simultaneously. It can output signals to both the first display panel and the second display panel, allowing one chip to perform multiple driving tasks that would traditionally require separate dedicated driving chips for each panel.
2Reliability
If multiple driving chips are used to drive multiple display panels, then each panel can be driven independently and reliably, but production cost increases
Solution Approach 1:
The patent combines multiple driving functions into a single driving chip, reducing the total component count. This merging directly lowers production costs by eliminating the need to manufacture, source, and assemble multiple separate driving chips, while still maintaining independent driving capability through integrated control logic.
Solution Approach 2:
The universal driving chip design allows a single component to replace multiple specialized driving chips, simplifying the manufacturing process and reducing costs associated with handling multiple different chip types, while maintaining the reliability of independent panel control.
3Reliability
If multiple driving chips are used to drive multiple display panels, then each panel can be driven independently and reliably, but power consumption increases
Solution Approach 1:
The patent merges multiple driving functions into a single driving chip, which reduces overall power consumption. The unified chip architecture allows for more efficient power management and signal distribution compared to multiple separate chips, while still maintaining the ability to independently drive multiple display panels when needed.
Solution Approach 2:
The universal driving chip consolidates the power requirements of multiple driving functions into a single power-efficient component, reducing the total power consumption that would be required to operate multiple separate driving chips, while maintaining full driving capability for multiple panels.
4Volume of moving object
If a single driving circuit drives multiple display panels, then device size is reduced and cost is reduced, but the driving circuit must manage multiple panels simultaneously increasing complexity
Solution Approach 1:
The patent applies segmentation by dividing the display system into distinct panels (first display panel and second display panel) that can be independently controlled through the unified driving chip. This segmentation allows the driving circuit to manage each panel separately through dedicated signal output paths, reducing the perceived complexity while maintaining compact integration.
Solution Approach 2:
The universal driving chip handles multiple panel control through integrated multi-functionality, which actually reduces complexity compared to having separate dedicated driving chips for each panel. The single chip manages multiple output channels and panel configurations through unified control logic, simplifying the overall system architecture.

AI summary
A display device includes a first display panel that displays an image in one direction in a first mode and includes a first pixel, a second display panel that displays the image in a direction opposite to the one direction in the first mode and includes a second pixel, and a driving circuit that provides a data voltage to a data line connected to the first pixel and the second pixel.
