Which technology is QLED and OLED stronger?

The entire color TV industry experienced a stormy washing in 2017. The Internet TV brand has been sluggish, and the market share of Internet TV has been falling. The entire color TV market has returned to the quality of itself. All major manufacturers are full of energy, and constantly explore new possibilities in image quality. Recently, it is rumored that Samsung is about to start trial production of QD-OLED, which is called the combination of QLED and OLED display .

 Which technology is QLED and OLED stronger?

Display technology is more than two poles

Laser TV is a self-contained one. Regardless of the LCD TV field, which display technology is the most intense debate on the future display technology trends, QLED and OLED, each of which has its own camp. In addition, WOLED, Micro-LED, inkjet printing technology and other concept terms have been derived. The development of display technology is blooming, and which technology will become the next generation display technology?

WOLED is not a true OLED technology

The OLED display technology is often referred to as RGB OLED. The three primary colors are independent pixels to form various colors. The color expression and contrast are excellent, but the material production and color stability control are difficult. Burning the screen phenomenon, resulting in high cost of the OLED screen. So there was an alternative solution for the birth of WOLED.

WOLED display technology uses a combination of white light and filter to achieve full color display, and three white light-emitting OLED diodes are added with RGB three primary color filter films to form visual three primary colors. It achieves white light uniformity, and has higher brightness and longer life. Of course, it is necessary to make concessions in color reproduction ability, and energy saving is not as good as RGB OLED panel.

Micro-LED technology is young, it takes time to get on the big screen

Micro-LED, as its name suggests, is a miniaturized LED. The miniature LEDs are arrayed, but transferred to the circuit substrate in batches, and finally the protective layer and the electrodes are added, and the display is made into a display screen. Because each pixel can be individually addressed and illuminated separately, the Micro-LED screen can achieve ultra-high contrast and a very beautiful picture. In theory, the pixels of Micro-LEDs have self-luminous properties, which are more efficient and more energy efficient.

However, it still can't shake the OLED dominance. In the final analysis, because of the immature technology, the biggest problem of Micro-LED is the high cost, low yield and difficult batch production. As a forward-looking display technology, in addition to first-tier companies such as Apple and Sony, the focus is mainly on Taiwanese panel makers. The success of Micro-LED has become the key to breaking the long-term monopoly of OLEDs by Korean companies.

Inkjet technology has a catch-up momentum

With the application of AMOLED display screens, the trend of evaporation technology and inkjet printing technology has gradually formed, and the latter has a great chance to catch up. Inkjet printing technology is the technology of printing OLED display pixels onto a glass or plastic substrate. This process technology will effectively increase the yield of large-size OLED flexible displays while reducing production costs.

Summary: Throughout the AMOLED market, Korean companies LG and Samsung have become the dominant players in the global display industry. Among them, Samsung has a market share of 95% on small-size OLED panels, which has almost monopolized the market. LG, which ranks second, has always had a dominant position in large-size OLED panels, with WOLED display technology and yields of over 80%. Dimensional TV applications have also achieved impressive results.

In the past few years, domestic panel makers have continued to exert their efforts to form a trend of local enterprises such as BOE, Huaxing Optoelectronics, Tianma Microelectronics, Hehui Optoelectronics, Visionox, and Xinli, and have a share in the small and medium-sized AMOLED field. In the large-size AMOLED field, its dominance is still in the hands of LGD. It is reported that BOE and Huaxing Optoelectronics have put the 10.5-generation LCD production line as the inkjet printing technology test production line. If it can achieve mass production, it will become the industry's first manufacturer to apply inkjet printing technology to RGBOLED.
