High-End Television Growth Reported
Flat panel and microdisplay rear-projection televisions may be pricey, but they are gaining market share. “Quarterly Global TV Shipment and Forecast Report” from DisplaySearch of Austin, Texas, says that total TV revenues are up 12 percent to $19 billion. This report looks at the third-quarter shipments and revenues for televisions by brand, region, size and resolution. Quarter-to-quarter growth in flat panel televisions is up across the globe, with the exception of Japan, where flat panel...
