Solution Overview
Problem
High-resolution liquid crystal display panels face a bottleneck in pixel charging time, limiting further improvements in resolution, especially in large-sized products using progressive scanning.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If progressive scanning is used in liquid crystal display panels, then the display structure is simple and easy to manufacture, but pixel charging time is reduced, preventing further improvement in pixel resolution
Solution Approach 1:
The display panel is divided into multiple independent display layers stacked together, with each layer having its own liquid crystal layer and pixel regions. By segmenting the display into multiple layers that can be independently controlled, the patent enables longer charging time per layer while achieving higher overall resolution through the combination of all layers.
2Manufacturing precision
If the resolution of liquid crystal display panels is increased, then display quality is improved, but pixel charging time is reduced, creating a bottleneck
Solution Approach 1:
The patent transitions from a single-plane display structure to a multi-layer stacked structure, adding the vertical dimension (z-axis) to the traditional two-dimensional display. This dimensional change allows the display to achieve higher resolution by combining multiple layers while maintaining adequate charging time for each individual layer.
3Manufacturing precision
If multiple display layers are stacked with independent data signal control, then pixel charging time is extended and resolution is increased, but device complexity increases
Solution Approach 1:
Multiple display layers are merged into a single stacked structure that functions as one integrated display unit. The layers are combined vertically with complementary pixel region arrangements, allowing them to work together as a unified system that achieves higher resolution while managing complexity through integrated design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The independent control of data signals in multiple layers doubles the pixel charging time, effectively increasing the resolution limit of the liquid crystal display panel.
Implementation Method 1
each of the liquid crystal layers comprises at least one pixel region and at least one non-pixel region
Implementation Method 2
a first polarizer disposed on a side of the first substrate away from the display layer, and a second polarizer disposed a side of the most bottom layer of the display layers away from the first polarizer
