industry, then it was replaced by RPTV because of its bad resolution. However

but it’s short-coming are high-cost, short-life; The flat Panel Display shows

power consumption

4K TV is TV of 4K resolution, as TV products

of new era, it’s with 4K HD technology and super-sized Display.  4K resolution is 4096x2160, 4 times as clear
