Engineering Contradiction Analysis
1Object-affected harmful factors
If a liquid crystal polymer layer is added to reduce external light reflection, then visibility is improved, but the overall thickness of the display increases
Solution Approach 1:
The patent applies a liquid crystal polymer layer that is less than 4 μm thick to reduce external light reflection. This thin film approach allows the display to maintain its self-emissive characteristics while minimizing reflection interference, and the thinness ensures the overall display thickness remains small.
Solution Approach 2:
The liquid crystal polymer layer's thickness is precisely controlled to be less than 4 μm, and its optical properties are optimized to delay light phase by 1/4 wavelength. These parameter changes enable effective reflection reduction while maintaining thin profile.
2Object-affected harmful factors
If the liquid crystal polymer layer thickness is increased to improve reflection suppression, then external light reflection is reduced, but the overall thickness of the OLED display increases
Solution Approach 1:
The patent employs an ultra-thin liquid crystal polymer layer with thickness less than 4 μm, demonstrating that effective reflection suppression can be achieved with minimal added thickness through optimized thin film design.
Solution Approach 2:
By optimizing the liquid crystal polymer layer thickness to be less than 4 μm and configuring it to delay light phase by 1/4 wavelength, the patent achieves effective reflection reduction without proportionally increasing overall display thickness.
3Object-affected harmful factors
If conventional anti-reflection solutions are applied, then external light reflection is reduced, but the display thickness and weight increase
Solution Approach 1:
The liquid crystal polymer layer with thickness less than 4 μm provides reflection reduction functionality with minimal weight addition, maintaining the lightweight advantage of OLED displays.
Solution Approach 2:
The optimized thickness parameter (less than 4 μm) and optical configuration of the liquid crystal polymer layer enable effective reflection suppression while minimizing weight increase.
