After more than a decade of dominating the television market, liquid crystal technology has come to the same situation as the kinescope technology of the year. It has been replaced by new display technology. Coincidentally, there were two kinds of new plasma display and liquid crystal display technologies that replaced the kinescope of the year. This time, there are two new technologies that replace liquid crystal technology: QLEDs and OLEDs, although there are no LCDs and plasmas. The gap is so great, but as a new technology in the television industry, there is still a huge difference.
What is the difference between QLED and OLED?
First of all, let's look at what is QLED. QLED is the abbreviation for Quantum Dot Light Emitting Diodes. Also known as QD-LED or QLED, QLED is an auto-illumination technology that does not require an extra light source. In addition, QLEDs have unique advantages in terms of color, and the color gamut can even exceed 100% NTSC color gamut. The color gamut coverage of traditional LED TV 72% NTSC and professional wide color gamut LED display 92% NTSC is far from.
However, QLED quantum dots, because of their vulnerability to heat and moisture, cannot achieve the same vapor deposition method as self-emitting OLEDs, and can only develop inkjet printing processes. At present, QLED technology is still in its infancy, and there are constraints such as low reliability/efficiency, unstable life of blue components, and difficulty in solution process development. It is also for this reason that QD TVs currently on the market are just optimized products for LCD TVs. For example, Samsung's SUHD is to add a complete quantum dot layer to the LED sandwich of LCD TVs. LCD TVs exhibit a wide color gamut (WCG), but there is still a problem. Quantum-dot TVs adopting photoluminescence technology are still LCD TVs, so the disadvantages of LCD products are still inevitable.
In contrast, OLED display technology has the advantages of self-luminescence, wide viewing angle, almost infinite contrast, lower power consumption, and high response speed. More importantly, OLED display technology products were launched in 2013. Although they are expensive, they still cause a commotion in the TV market, and even have the voice of "OLED TVs will become the next year's development direction."
In addition, OLEDs are products that are flexible, flexible, capable of presenting future display technologies, and capable of leading a new generation of display technologies. The eutectic temperature of the OLED is relatively low, and the plastic matrix can be used in place of the glass matrix, and the display can be more smoothly manufactured. At the same time, the OLED does not need a backlight source, and therefore it is evaluated as the best technology for manufacturing a transparent display.
In the face of these two display technologies, domestic TV manufacturers are also clearly divided into two groups, namely, Hisense, which focuses on quantum dots (QLEDs), and Skyworth, TCL, which focuses on OLEDs. So what is happening to many Internet TV manufacturers? At present, Internet TV does not have much contact with such cutting-edge display technology. Only Coolo launched an OLED product, the Cool Open T55, which also makes Cool Open the first Internet TV manufacturer to contact the new display technology.
Cool open as an Internet manufacturer, why can we use the OLED display technology Cool open T55 when many traditional manufacturers have not yet launched OLED display technology products? In addition to the special relationship between CoolOpen and Skyworth, the company is also relentlessly pursuing new technologies. This pursuit not only allowed CoolOpen to launch the first OLED display technology TV products, but also allowed CoolOpen to stand in 2016. The top three positions of Internet TV manufacturers. After entering 2017, both QLEDs and OLEDs will usher in an outbreak, and they have already had a cool start in OLED display technology. The accumulation of new display technologies has taken precedence over other Internet TV manufacturers. It will usher in a huge period of growth, and it is very likely to become the leader of Internet TV manufacturers.

FR-4 epoxy glass fiber cloth substrate is a kind of substrate with epoxy resin as the adhesive and electronic grade glass fiber cloth as the reinforcing material. Its adhesive sheet and inner core thin copper-clad board are important base materials for making multilayer printed circuit boards.
The epoxy glass fiber cloth substrate has higher mechanical properties, dimensional stability, impact resistance, and moisture resistance than paper substrates. Its electrical performance is excellent, its working temperature is high, and its performance is less affected by the environment. In terms of processing technology, it has great advantages over glass fiber cloth substrates made of other resins. This type of product is mainly used for double-sided PCBs and is used in large quantities.
