Samsung Electronics and LG Electronics are competing against each other again over TV. Until now, 토토사이트
the two companies have been fiercely competing to develop technologies to decide who provides clearer image quality. A place where these two companies are also going to collide this year is Consumer Electronics Show (CES 2019) that will be held in Las Vegas from the 8th to the 11th (U.S. time).

LG Electronics made an announcement on the 3rd that it will introduce 88-inch 8K OLED TV at CES 2019. 88 inches is the largest OLED TV ever. Samsung, which boasts the worlds largest TV market share, is also going to introduce 98-inch super-large 8K QLED TV at CES. 8K is 4 times higher in resolution than current 4K (ultra-high quality) at 7680×4320 pixels.

Samsung and LG have been focusing on QLED and OLED respectively for many years. Old is an expression that LG has created by reading the English abbreviations of OLED (Organic Light Emitting Diode) as loud as they LG Electronics has been working hard to popularize OLED TVs since third quarter of last year by selling 55-inch OLED TVs at 200,000 won, which is 300,000 won lower than previous ones.

Unlike LCDs, OLED has no backlight. Because it is self-luminous, backlight units (BLU) such as LCDs are not needed. Because there is no backlight, panels are as thin as paper and have excellent contrast. On the other hand, there are disadvantages that yield is currently lower and that price is higher than LCD products and that there is more to it.

Quantum-Dot, which is used by Samsung for QLED, is a semiconductor that is 2 to 10nm size. By letting each quantum dot particle emit its own light instead of backlight of LCD, it can theoretically implement better quality than OLED. Production process is simpler than OLED and electricity consumption is lower. However it has to increase lifespan, reliability and efficiency of quantum dot devices in order to mass-produce QLEDs.
Since Samsung Electronics first introduced TVs that are applied with Quantum-Dot technology in 2015, it has been distancing itself from OLED TV by releasing TVs that have upgraded its technologies every year. "In order to respond to OLED, Samsung Electronics is using QLED strategy instead of Quantum Dot from UHD TVs." said a representative for an industry. Unlike Samsung, LG is currently playing a leading role in OLED field among TV panel markets. As Sony and Panasonic also released OLED TVs last year, they are receiving LG Displays panels as well. According to a market research company called IHS, LG Electronics global market share (based on sales) increased from 13.6% in 2016 to 16.8% in third quarter of last year.

Chinese companies have continued to grow rapidly in the TV market, chasing Samsung and LG. BOE in particular succeeded in developing its first 55-inch 4K OLED display by using so-called inkjet printing technology. "If China bypasses current method of production in large OLED markets and succeeds in going straight to inkjet printing, there will be a situation that threatens South Korea in next-generation TV panel markets as well." said a representative for this industry.
