What They Say
The Elec reports that Samsung will start production of its microLED TVs using LTPS modules for the first time in Q3 after being delayed from an initial plan of May (Samsung MicroLED TVs Delayed). Up to now it has used PCBs. The use of LTPS glass modules will allow finer pitch and the company will make an 89″ UltraHD panel (that’s a 0.51mm pitch by our calculation). The Elec reports that LTPS may then be used on 101″ and 114″ sets. The LEDs are said to be 34 x 85 ?m in size and supplied by PlayNitride of Taiwan.
We have previously reported that Samsung wanted to use a 12.7″ LTPS module that could be supplied by AUO or SDC.
What We Think
Glass has a number of advantages in being more stable and flatter than PCBs and putting the driving on the back of the glass also means fewer chips. However, it is not going to be very cheap and the option of accessing LTPS is partly because of the weakness in demand for LTPS panels for smartphones which are moving in the higher end to OLED with technologies such as LTPO. I covered the topic of LTPS modules in more depth some seven months ago Seamless Tiled Displays – A Bit of a Challenge. I’m planning a couple of Display Daily issues in the next few weeks to look at the topic again with more detail. (BR)
