Samsung is focusing on developing the QD-OLED screen with many advantages compared to OLED

Tram Ho

According to recent information, Samsung will close all production lines of liquid crystal display (LCD) by the end of this year, including 2 production lines in Korea and 2 production lines in China. However, the company will still complete all existing orders by the end of this year. There are some predictions that Samsung wants to shift its focus from LCD to QD-OLED screen. Their development plan is to focus on quantum TV production and these TVs will use QD-OLED displays. In addition, Samsung will spend about $ 11 billion to build a factory capable of producing true QD-OLED TV screens.

What is QD-OLED?

In simple terms, flat-screen TVs are divided into LCD and OLED TVs. If the LCD works by using a backlight mechanism, then the OLED is a screen that automatically emits light. LED panels and quantum dot panels are both developed based on LCD panel technology.

While LCD panels use CCFL fluorescent lights, LED TVs use LEDs. Technically, there is no difference in image quality between the two types of panels. However, LED screens are more energy efficient, produce less heat, and are thinner.

Speaking of quantum dot technology, it no longer uses white LED backlight, but uses inorganic nanocrystals that can emit different colors to serve as a light source for the backlight. It has a higher color range coverage and more accurate color reproduction. Many TVs and quantum dot computer monitors on the market now have 100% NTSC color bands and 130% sRGB color bands.

OLED displays use very thin coatings made of organic material and glass substrates, which glow when electricity flows through them. OLED screens can be lighter and thinner, and the viewing angles are also wider. The downside of this screen is that you always face the risk of ghosting, and its price is also very high

The advantages of QD-OLED panels

Samsung’s upcoming QD-OLED panel retains the advantages of OLED. In addition, it uses quantum dot technology to provide a wider range of colors and higher brightness. Its principle of operation is a combination of quantum dots and OLED. Because the OLED in the QD-OLED panel emits only one color, the manufacturer will reduce the level of production fairly and lower production costs.

It also has wider color range coverage and higher brightness than OLED. Moreover, the QD-OLED panel greatly reduces the appearance of ghosting. Simply put, the quality of the QD-OLED panel can surpass that of OLED and the price is much lower. What a promising display technology.

Although the QD-OLED solution is attractive, it will not be able to bring OLED to the edge for the following reasons:

– OLED technology is very mature, and as it continues to improve, prices will drop dramatically.

– At this time, QD-OLED is still an experimental product. There is no evidence to guarantee product quality.

– QD-OLED technology is not mature enough, at present, mass production is not possible.

– Because QD-OLED is a new technology, its price will be as high as OLED even though it is expected to have lower prices.
