Xiaomi left everyone speechless when at the event to celebrate its 10th birthday it presented to the world a 55-inch TV with a completely transparent OLED display, ready for mass production and then for retail marketing.
Transparent TVs are certainly nothing new: LG and Panasonic led the way in this technology months ago. However, Xiaomi is the first to actually reach the market. For this reason, he wanted to explain with a brief insight some steps of the realization process.
The first step to make a TV completely transparent is pretty obvious, take whatever is normally behind the screen and move it elsewhere. Xiaomi did exactly this: all the electronics and audio components are in fact moved inside the swivel base, which also supports the panel.
Although this is a rather risky choice due to the limited space available, Xiaomi has seen fit to integrate a dedicated cooling system, through a heat sink and some ventilation grids, which favor the recirculation of air.
Let's move on to the type of panel used: Xiaomi has opted for an AMOLED display, given the absence of any type of backlight. However, to make it completely transparent, the engineers had to make some changes to the RGBW matrix.
To achieve the final effect, only half of the panel is actually covered with pixels – the other half is transparent. The grid is so dense that from a normal viewing distance the eye cannot perceive this inhomogeneity and this fascinating transparency effect emerges. An optical illusion, shall we say, made possible by the physiological limitations of the human eye. The image depicting the parrot instead compares the traditional OLED panel with the modified RGBW matrix one, used on the Xiaomi Mi TV LUX. The sub-pixels are on the right, while the area on the left is transparent.
Finally, Xiaomi explained that it has implemented a proprietary solution to protect the panel from stresses and possible bumps. A thin layer of glass is in fact glued directly to the surface of the display, using a UV curing glue. Then, a thin metal frame runs along the perimeter of the glass in order to increase its rigidity.
A highly respectable product, therefore, but not yet within everyone's reach, given the rather high selling price – 49,999 Yuan (6,115 euros at the exchange rate).
