Solution Overview
Problem
Liquid crystal display devices face issues with bruising and pooling effects due to user interaction, which affect image quality and viewing angles, and require complex constructions and manufacturing processes, especially when using supporting frames or spacers.
Innovation Solution
The use of liquid crystal display devices with minute liquid crystal capsules and red, green, and blue pigment structures without a color filter or retardation film, where the liquid crystal molecules are enclosed in polymer layers and aligned relative to polarization plates at specific angles, reducing the need for additional alignment layers and spacers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If supporting frames or spacers are disposed between substrates to prevent bruising and pooling effects, then image quality is improved, but device complexity and manufacturing complexity increase
Solution Approach 1:
The invention extracts and removes the supporting frame or spacer from the liquid crystal display device construction. By eliminating these additional components, the patent achieves the same protective function (preventing bruising and pooling effects) through the liquid crystal layer itself, thereby reducing device complexity and manufacturing complexity while maintaining image quality
Solution Approach 2:
The liquid crystal layer is made self-sufficient by enabling it to prevent bruising and pooling effects without external supporting structures. The liquid crystal molecules inherently resist deformation and maintain orientation stability when pressure is applied, allowing the layer to protect itself and eliminate the need for additional supporting components
2Reliability
If supporting frames or spacers are disposed between substrates to prevent bruising and pooling effects, then image quality is improved, but manufacturing processes become complicated
Solution Approach 1:
The invention removes the supporting frame or spacer components from the manufacturing process. By eliminating these additional parts, the patent simplifies the manufacturing process while maintaining the protective function through the liquid crystal layer's inherent properties
Solution Approach 2:
The liquid crystal layer performs the protective function independently without requiring additional supporting components to be manufactured and assembled, thereby simplifying the overall manufacturing process
3Ease of operation
If liquid crystal molecules are allowed to orient freely when pressed, then ease of operation is improved, but harmful bruising and pooling effects occur
Solution Approach 1:
The invention converts the harmful effect of pressure-induced liquid crystal deformation into a beneficial response. When pressure is applied, the liquid crystal molecules reorient in a controlled manner that maintains display functionality while preventing permanent damage, effectively transforming the harmful bruising effect into a reversible, controlled orientation change
Solution Approach 2:
The invention changes the physical parameters of the liquid crystal layer, specifically its elasticity and viscosity, to enable it to resist deformation under pressure. By adjusting these parameters, the liquid crystal layer can maintain its structural integrity and prevent harmful pooling effects while still allowing for controlled orientation changes during touch operation

Implementation Method 1
When an electric field is generated in each pixel by applying voltages to transparent electrodes formed on the substrates, orientation of the liquid crystal molecules may be changed to display the images.
Implementation Method 2
When the electric field is not generated in each pixel, the liquid crystal molecules may be returned (or recovered) to an initial orientation thereof.
Implementation Method 3
The red, the green and the blue liquid crystal structures may include a red pigment structure, a green pigment structure and a blue pigment structure, respectively. The red, the green and the blue pigment structures may respectively include a red pigment, a green pigment and a blue pigment mixed with binders, surface-active agents and/or additives.
