Samsung would be preparing the launch of Mini LED TV in 2021. The indiscretion comes from Taiwanese sources: the Korean giant would currently be in contact with Epistar, Lextar, Sanan and HC Semitek, companies active in the supply of the chips necessary to achieve the backlight of Mini LED TVs. Samsung is expected to receive its samples in September 2020.
According to the calculations of Trendforce, a company specialized in market analysis, more than 12,000 chips are needed to create a 65 "8K TV with Mini LED (with an average size between 100 and 200 micrometers), a number that rises to over 20,000 for an 85 "model. If Samsung Mini LEDs actually hit the market in 2021, it is estimated that the sales target will be set at over 3 million units. More than 30 billion chips will be needed to produce such a quantity of televisions.
As for the type of Samsung Mini LED, the sources assume the use of passive matrix technology. It would therefore be a solution similar to that which is used on the TCL X10 series. The Chinese giant has already presented the direct evolution at CES 2020. We refer to Vidrian, a technology that is instead an active matrix. The difference lies in the structure: the active matrix Mini LEDs use semiconductors and tens of thousands of tiny diodes infused directly onto a transparent glass substrate with a metal oxide surface.
What are the advantages of Mini LEDs? This technology allows to produce Full LED Array Local Dimming LCD TVs equipped with a much higher number of diodes; hence the possibility of piloting the backlight on a much greater number of independent control zones (many areas are not sufficient by themselves: we talked about it in our guide). Mini LEDs would substantially improve (at least on paper) the backlighting of Samsung's high-end or medium-high end products. QLED (LCD with Quantum Dot) such as the 8K series or the most performing Ultra HD would benefit from it.
Of course it will take time to understand if the indiscretions prove to be correct.
