Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If liquid crystal display technology uses multiple polarizers, then the display function is achieved, but light transmission rate and utilization efficiency are restrained
Solution Approach 1:
The invention extracts and removes the polarizer layers from the display system, replacing them with a micro mirror array that directly controls light reflection and transmission. This extraction of the polarizer component eliminates the light loss associated with multiple polarizer layers while maintaining the display function through alternative optical control mechanisms.
Solution Approach 2:
The invention replaces the optical-based polarizer system with a mechanical micro mirror array system. The micro mirrors mechanically tilt to control light direction, substituting the optical polarization mechanism with a mechanical reflection control mechanism, thereby improving light transmission efficiency.
2Reliability
If liquid crystal display technology uses multiple polarizers, then the display function is achieved, but power consumption increases
Solution Approach 1:
By removing the polarizer layers from the system, the invention eliminates the energy loss associated with light absorption and reflection in multiple polarizer interfaces. The micro mirror array requires less energy to control light transmission, thereby reducing overall power consumption while maintaining display functionality.
Solution Approach 2:
The micro mirror array utilizes electrostatic actuation that can be driven by low-power signals. The mirrors passively reflect and redirect light without requiring continuous energy input, allowing the display to maintain its function with minimal power consumption compared to the active polarizer switching required in liquid crystal displays.
3Illumination intensity
If a display panel is formed based on micro mirror array assembly and filter, then light transmission and utilization efficiency are enhanced, but the need for polarizers is eliminated
Solution Approach 1:
The invention merges the micro mirror array assembly with the color filter layer into an integrated display panel structure. This combination eliminates the need for separate polarizer layers and reduces the overall number of components, simplifying the device structure while enhancing light utilization efficiency through the synergistic operation of the micro mirrors and filters.
