In the recent IFA exhibition in Germany, South Korean company Samsung demonstrated the evolution of the display industry, and has the intention to hint to the outside world QLED (quantum dots) is the future display trend. This of course caused the LG's dissatisfaction with OLED's heavy re-injection, so it followed the counterattack and revealed the deficiency of QLED from the technical level.
Samsung and LG are not once or twice torn in display technology. As a leading company in the display industry, its every move is related to the future interests of its own business and the right to speak of industry development. It is also normal that we do not agree with each other in this regard.
So, as two infinitely possible technologies, is it really necessary to tear each other?
Before answering this question, let us first understand the two technologies of OLED and QLED.
OLED, also known as organic light-emitting diodes, can be said to be a revolutionary in the display industry.
Its structure is very simple. It consists of a thin and transparent indium tin oxide (ITO) with semiconducting properties, which is connected to the positive electrode of the electricity, and another metal cathode that is packaged into a sandwich structure to form an OLED.
Because of its self-luminous characteristics, it has directly abandoned the traditional liquid crystal display technology that requires liquid crystal panels and backlights. And its light-emitting principle is also very simple, using a very thin layer of organic polymer material and glass substrate, when the current passes, the organic material will emit light, do not need the backlight source at all.
Compared with the traditional LCD technology, due to the simplified structure, OLED can be more lightweight, more energy-efficient and environmentally friendly; without the problems caused by uneven LCD backlight, the color display will perform better, and the contrast is also unlimited. Large; no LCD defects - smear problem, that is, the response speed of the dynamic screen, which has always been the criticism of traditional LCD technology, and OLED does not have these defects, can be said to respond faster; Finally, there is no The health hazards caused by high-frequency blue light, the self-luminous nature of the OLED does not have the "highlighted lamp beads" in the traditional liquid crystal display, can directly ignore the blue light damage, it can be said that OLED in this regard is more healthy eye protection.
However, the defects of OLED are also obvious. The biggest flaw is the high price. As the current mainstream or LCD technology, OLED is basically in its infancy, so its production costs are very high, which is why the market is not yet popular. Industry insiders speculate that Samsung, Sony and other vendors have all launched OLED TVs and soon gave up. High production costs may be the main factor.
QLED, also known as QD LED, can be said to be a guardian of the display industry from outside rumors.
According to the vice president of OLED sales, the quantum dot TV on the market currently only adds a quantum dot film to the LCD, which means that it still belongs to the traditional LCD technology. Similar to the previous CCFL (cold cathode fluorescent tube) and WLED (white light emitting diode).
The principle is also very simple. The red and green quantum dot optical materials with different diameters are illuminated by a blue backlight to form three primary colors of red, green and blue (RGB), and then an image is formed by an imaging system and a drive system such as a filter film. This kind of technology calls quantum dot backlight technology from the professional level, mainly solve the problem that the ordinary LCD TV backlight color is not bright enough to reach the best visual experience.
For Samsung's choice of QLEDs, rumors are generally the case. However, is QLED really just like this?
Quantum dot light-emitting diode display technology based on electroluminescent properties is the QLED in Samsung's mouth! This is a more advanced application of quantum dots in the display technology field, which is not currently appearing in the market.
It is no longer that blue light produces a white light through a layer of quantum dot material to illuminate the LCD screen, but instead is driven directly by electricity, causing the quantum dot itself to emit light and produce images by color mixing.
Since the quantum dot itself emits light, the liquid crystal is no longer needed, and the color film also eliminates the backlight unit. This makes the QLED and OLED have similar principles in the display mode.
Compared to OLEDs, QLEDs can emit very pure and high-quality monochromatic light of various colors according to their diameters. However, OLEDs must pass a filter to obtain a solid color. Although the colors used for filtering are more pure, There will also be distortion; and quantum dots use inorganic materials that are not easily oxidized; and most importantly, QLED materials have low costs. From these aspects, QLED seems to be even better.
However, OLEDs have become increasingly prevalent in the market, and a large number of media reports have also accumulated many advantages.
In general, QLEDs are good and OLEDs are worth mentioning. Both technologies have evolved from traditional LCD technology, and they have all been innovative enough. In the future, both technologies have infinite possibilities.
As for who can lead the trend of the industry, who can become the overlord of a new generation of display technology, the market has the final say.
