A 50-inch TV that will have set you again $1,100 at Greatest Purchase throughout Black Friday 2001 now prices lower than $200, and the value per area-pixel — a metric accounting for each display screen dimension and determination — has dropped by greater than 90% over the previous 25 years. The story behind this decline is essentially one in every of liquid crystal show know-how maturing from a distinct segment product to a mass-manufactured commodity.
LCDs represented simply 5% of the TV market in 2004; by 2018, they commanded greater than 95%. The most important driver of price discount has been the scaling up of “mom glass” sheets — the massive panels of extraordinarily clear glass onto which semiconductor supplies are deposited earlier than being minimize into particular person shows. The primary era sheets measured roughly 12 by 16 inches. Immediately’s Era 10.5 sheets span 116 by 133 inches, practically 100 occasions the unique space. This scaling delivers substantial financial savings as a result of tools prices rise extra slowly than glass space will increase.
Shifting from Gen 4 to Gen 5 mom glass minimize the price per diagonal inch by 50%. Gear prices per unit of panel space fell 80% between Gen 4 and Gen 8. Course of enhancements have compounded these good points: masking steps required for thin-film transistors dropped from eight to 4, yields climbed from 50% to above 90%, and a “one drop fill” approach diminished liquid crystal filling time from days to minutes.
