Transparent OLED screens aren't anything new — LG has had a digital signage solution on the market for some time. That said, Xiaomi's Mi TV LUX Transparent Edition will be the world's first mass-produced transparent OLED TV. Revealed as part of the company's 10th anniversary, it hides the processing units in its base stand, leaving the 55-inch screen completely clear when turned off. Specs include a 150000:1 static contrast ratio and an infinite dynamic contrast ratio, 120Hz refresh rate, and Dolby Atmos support. The set goes on sale in China on August 16th.
