I misread the word development in the title to mean no longer manufactured instead of no longer improved upon.
Does that mean LED-LCD TVs dead in the water? Not necessarily. As we’ve seen from Vizio, TCL, Samsung, LG and Sony, there’s still a huge demand for lower-cost LED-LCD TVs as well as LED-LCD monitors. Those will continue to be produced for years to come — and will likely continue to drop in price — just don’t expect to see many improvements on them compared to their more expensive counterparts.
Did you read a different headline? What you said doesn't contradict the headline that I read, which is: "It’s official — LCD TVs won’t see any further development."
Obviously there are other TV technologies that will continue to be developed, as the subtitle points out: "OLED and MicroLED are the future."
