Samsung researching quantum dot on MicroLED TVs

Samsung Electronics has been researching ways to apply quantum dot (QD) technology to its MicroLED TV, the firm's TV boss has said.

"We are planning to produce and supply [MicroLED TVs] from Vietnam," Han Jong-hee, head of Samsung's visual display business, said at a launch event for its 2018 model QLED TVs[1] in Seoul.

Samsung is fixed on releasing a 146-inch model -- the size unveiled at CES[2] earlier this year -- but is yet to determine the maximum and minimum sizes, the president said.

Prices will be announced in June, and the company will take into consideration that its 110-inch UHD TV costed $149,900 when first launched, Han said.

On applying QD technology to MicroLED TVs, the president said it required a very high level of technological sophistication to put QD on micrometer-sized LED invisible to the eye. "MicroLED requires RGB to form at the wafer. If we can apply QD technology and increase productivity we can save costs," he added.

Han denied rumors that Samsung is planning to launch a OLED TV, but said there was a research project within the company that is attempting to combine QLED and OLED technology.

The company is also on track to launch its much teased MicroLED TV, called The Wall and unveiled at CES 2018, in the second half of the year.

MicroLED TVs[3] use micrometer-sized LEDs to form a display. Like organic light-emitting diode (OLED), the tech doesn't require a back light but uses inorganic material. Rival LG Electronics is using OLED for its premium TVs.

MicroLED patent filings from both global and local firms in South Korea doubled in 2017[4].
