CPI
A transparent film material used in foldable-screen smartphones as an alternative cover solution, characterized by flexibility.
Timeline (last 90 days)
CPI polymer film bends better but is prone to creases and has poor scratch resistance.
Repeated opening and closing of a foldable phone subjects the material in the folding area to cyclic fatigue, and when the hinge applies uneven pressure or foreign matter gets in, cracks may initiate and propagate from the crease.
CPI has excellent flexibility, but its hardness and scratch resistance are inferior to glass.
Foldable phones typically use transparent polyimide (CPI) film or ultra-thin flexible glass (UTG) as the cover material.
The mainstream approach for foldable inner-display cover layers is to stack a surface-treatment layer on ultra-thin flexible glass (UTG) or transparent polyimide (CPI) film.
Spain has a dedicated 'Commission for Intellectual Property' (Comisión de Propiedad Intelectual, abbreviated CPI) responsible for evaluating and enforcing blocking orders.
Under cost-per-install (CPI) or cost-per-conversion pricing models, each install corresponds to one expenditure by the advertiser.
UTG technology raises screen hardness from the 2-3H of CPI materials to 6-7H.
The CPI (Colorless Polyimide) plastic film used in early foldable screens had a hardness of only 2-3H and was highly susceptible to scratches.
For every $1 per gallon increase in diesel prices, the U.S. Consumer Price Index (CPI) may rise by approximately 0.3–0.5 percentage points
