Solution Overview
Problem
Residual charges accumulate in liquid crystal display panels due to electrostatic factors, leading to afterimages as the gray-scale voltage is removed, causing display issues.
Innovation Solution
A liquid crystal display panel design featuring conductive layers and projections on the substrates that connect upon external compression, allowing for the neutralization of accumulated charges at the pixel and common electrodes, eliminating residual images without additional pressing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional liquid crystal display panel structure is used, then the device is simple and easy to manufacture, but residual charges accumulate on the substrate causing afterimages
Solution Approach 1:
The invention divides the substrate into multiple regions with different electrical properties by forming protrusions at specific locations (pixel electrode region and common electrode region). Each protrusion serves as a separate charge elimination path, segmenting the charge discharge function across different spatial locations to effectively remove residual charges from both electrodes.
Solution Approach 2:
The protrusions act as intermediary structures that physically bridge the gap between the first substrate and second substrate when compressed. These protrusions conduct residual charges from the pixel electrode and common electrode to the opposite substrate, serving as a mediator for charge elimination without requiring additional external pressing operations.
2Reliability
If additional pressing operations are implemented to eliminate charges, then residual images can be removed, but the ease of operation deteriorates
Solution Approach 1:
The protrusions are designed to automatically eliminate residual charges through normal user touch operations. When the user touches the display screen, the compression force naturally activates the protrusions to conduct charges, making the charge elimination function self-service without requiring the user to perform additional pressing actions specifically for charge removal.
Solution Approach 2:
The protrusions are designed with flexible properties that allow them to dynamically change their state based on external compression. In the normal state, the protrusions maintain a distance from the opposite substrate. When compressed by user touch, the protrusions elastically deform and contact the opposite substrate to eliminate charges, then return to their original state, providing a dynamic charge elimination mechanism.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively eliminates residual images caused by charge accumulation through external compression, enhancing display quality and convenience by neutralizing charges during touch operations without additional pressure.
Implementation Method 1
When the first substrate and the second substrate are close to each other due to external compression, the first conductive layer contacts with the second substrate and thereby electrically connects with the charge storage area on the second substrate, which eliminates the accumulated charge thereon
