Sony invited us to its headquarters in Japan to take a look at some prototype technology the company is working on to make some of the best TVs, like the Sony A95L OLED TV, even better. In addition to close-up looks at a sound-mapping robot and the professional-grade Sony BVM-HX3110 master monitor, Sony showed us a prototype technology that could give the company’s Mini-LED TVs in particular a serious edge over the competition.
