TCL may show qd-oled TV based inkjet production process in September 2021
TCL has announced that it may exhibit a television with a quantum dot OLED panel during next year’s IFA fair. It would then have been made using an inkjet printing method.
The product development director of TCL for the European market, Marek Maciejewski, says that such a television may be shown at next year’s Berlin electronics fair and that prototypes are already ready. He recently told an editor of the Display Daily website. Maciejewski indicated that the Japanese manufacturer Joled is one of the panel suppliers and that there will be more suppliers. This makes TCL the first manufacturer to say it will show a QD-OLED TV next year.
It may also concern Samsung Display, which was recently said to have already supplied quantum dot OLED panels to Samsung Electronics, Sony and Panasonic. This screen component from Samsung previously announced that it is on track to start producing quantum dot OLED panels for TVs sometime next year. QD OLED TVs use blue OLEDs and quantum dots. In addition, red and green ‘filters’ are used for the color conversion, to create sub-pixels of those colors.
A few months ago it turned out that Joled has entered into a partnership with TCL CSOT, a screen component of TCL. As part of the deal, TCL is investing the necessary money in Joled and the two companies commit to develop large OLED panels. The Japanese Joled has been researching the printing of OLED panels since 2015 and is currently already supplying smaller OLED panels to smartphone manufacturers and for PC monitors.
As part of this collaboration with TCL, Joled would use its own printing technology, which should reduce the costs of making OLED panels. This differs from the production process that, for example, Samsung Display would use for the production of panels based on blue OLEDs; evaporation is used to put the different layers on top of each other. According to Display Daily, Samsung Display already uses inkjet printing technology to manufacture the quantum dot color conversion filters, so that the company can probably also use this technology for the blue layer.
