8524.91 - Of liquid crystals:

This HTS category, 8524.91, specifically covers flat panel display modules that utilize liquid crystal display (LCD) technology. These modules are designed to present visual information and can be integrated into a wide range of electronic devices. The key characteristic is their reliance on liquid crystals to manipulate light and create images.

Distinguishing this category from its siblings is crucial for accurate classification. While sibling category 8524.92.00.00 covers displays employing organic light-emitting diodes (OLEDs), and 8524.99.00.00 encompasses all other types of flat panel displays not specified elsewhere, 8524.91.00.00 is exclusively for those employing liquid crystal technology. This difference is based on the underlying display technology and the operational principles of the light emission or modulation.

Within this category, further subdivision exists. Subcategory 8524.91.10.00 delineates LCD flat panel display modules that are not intended for specific types of display apparatus classified under subheadings 8528.59, 8528.69, 8528.72, and 8528.73. Subcategory 8524.91.90.00 then covers all other LCD flat panel display modules not falling into the preceding subclassifications, ensuring a comprehensive classification for all liquid crystal-based flat panel display modules.
