The STEVAL-NRG011TV board from STMicroelectronics helps designers quickly build 200W digital-power supplies and adapters for LED and OLED televisions to exceed the toughest energy-efficiency and standby regulations. Based on ST’s STNRG011 digital PFC (power-factor correction) and resonant LLC converter, the STEVAL-NRG011TV combines a proven and reliable topology with the ability to configure and fine-tune the operating parameters for optimal…
Invention Story of Television
Towards the end of 1800s, images were transferred through fax machine for the first time. Soon after telephone came into being, electrically powered transmission of moving TV images, known as telephonoscope, was started.
