Liquid Crystal Panel Nano-Imprinted Gate Layer Thickness Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The thickness of liquid crystal panels in conventional LCDs is increased due to excessive optical films in the backlight module, necessitating a reduction in thickness while maintaining functionality.
Innovation Solution
A liquid crystal panel is fabricated with a first metal wire gate layer formed through nano-imprinting between the backlight module and the array substrate, using metals like aluminum, iron, copper, chromium, or gold, with wire dimensions less than 60 nm in width and 120 nm apart, to reduce thickness without compromising performance.

Engineering Contradiction Analysis
1Illumination intensity
If multiple optical films are used in the backlight module to convert point light source into surface light source, then the light distribution function is improved, but the panel thickness increases
Solution Approach 1:
The patent combines the light distribution function with the polarizing sheet by forming a light guide plate on the polarizing sheet. This integration merges multiple functional layers (polarizing function and light guiding function) into a single component, eliminating the need for separate optical films and reducing overall panel thickness while maintaining the surface light source conversion function
Solution Approach 2:
The polarizing sheet is given multiple functions: it serves as both the polarizing element and the substrate for the light guide plate. The light guide plate itself performs both light distribution and structural support functions. This multi-functionality reduces the number of separate components needed, thereby reducing panel thickness
2Length of stationary object
If the number of optical films is reduced to decrease panel thickness, then the thickness is reduced, but the light conversion function may be compromised
Solution Approach 1:
By forming the light guide plate directly on the polarizing sheet, the patent combines the light distribution function with the polarizing function in a single integrated structure. This ensures that the light conversion from point source to surface source is maintained while using fewer separate optical films, thus reducing thickness without compromising function
Solution Approach 2:
The light guide plate is designed with a specific patterned structure (including light guiding portions and light reflecting portions) that segments the light path in a controlled manner. This segmentation allows efficient light distribution across the surface while maintaining a thin profile, ensuring the light conversion function is preserved despite reduced thickness
