How do you see the future of display technology? Why will OLED become the absolute leader of future

With the introduction of new forms of products such as flexible displays, transparent displays, holographic displays, and ultra-high-resolution displays, car interiors, walls and windows, home and appliance surfaces, and even clothing and bags may become display interfaces in the future, and the explosion of display product applications has kicked off. From "Internet of Everything" to "Display Everywhere", OLED is becoming the absolute leader in the future of display. OLED in the display of diversification, ultra-thin, flexible curl, can meet the needs of more future scenarios, its great commercial value lies in any space can be made into a display, its influence will also be reflected in consumer electronics, intelligent transportation, smart home and other fields.

QLEDTV compared with OLEDTV,It has the advantages of high color purity、Strong color reproduction ability、High brightness and long life,Although OLEDTV has a slight advantage in black purity,But its limitations in weak current control lead to its poor realization of dark field details,It cannot fully display the effective contrast of the light used in life,In additionOLEDTV also has two very fatal shortcomings,That is, it is easy to burn the screen and has a short service life,The most important thing is that OLED TV is expensive, Under the same configurationOLEDTV is about 2 times more than QLEDTV,ThereforeOLEDThe application on the small screen of the mobile phone is more,The mobile phone has been changed in 2-3 years,And the TV is different,With a 10 years8 years,OLEDThe big screen has no advantage。

1. Compared with LCD screens, there is less backlight unit and liquid crystal grating layer;

2. It is equivalent to a semi-finished screen, leaving sufficient space for redevelopment and utilization, all components are split, compared with conventional commercial screens, the hardware is more scalable, and it is more suitable for exhibition applications;

3. The packaging structure at the back is made of transparent material, which is the transparent screen of Shanghai Xianshi Goodview, which benefits from the absence of a backlight unit and a liquid crystal grating; If I can help you, please give a big thumbs up.

If we want to classify the screen material of the mobile phone, we can divide it into two major factions, namely LCD screen and OLED screen.

Generally speaking, today's flagships will be equipped with OLED full screens, while LCD screens are mostly found on low-end models (except iPhones). So the question is, why are almost all flagship phones now abandoning LCD screens and switching to OLED screens?

In fact, no matter what kind of mobile phone, the most interactive contact with the user is the screen. OLED screens can bring very stunning display effects. Because OLED has the characteristics of self-illumination, compared with LCD, the former has stronger color expression, whether it is color gamut coverage or contrast, it is incomparable to LCD screens.

If you put the OLED screen and LCD together, and at the same time**same**, the difference between the two is clear at a glance. When displaying a pure black background, the OLED screen only needs to turn off the illumination mechanism to bring pure black, while the LCD screen needs to shield the white light source, so it cannot be pure black.

If you let good things describe these two screens in easy-to-understand words, it is "one hard" and "one soft".

The LCD is mainly composed of two glass plates, which are also interspersed with materials such as polarizers. The LCD screen can only output the picture by illuminating it with a backlight. Because of this, some LCD screens will leak light after being used for a long time.

The OLED screen is much more simplified in structure, and only needs to pass through the film and plastic substrate to complete self-luminescence. Since the OLED screen does not need a backlight module, it can be made thinner in thickness.

In other words, the OLED screen material itself is relatively soft and highly malleable, and it only needs to go through a certain manufacturing process to show it in a variety of shapes in front of users. It has to be mentioned that only OLED screens can be bent and folded at large angles, and harder LCD screens are only suitable for straight-screen mobile phones.

As mentioned above, the plasticity of OLED screen is far stronger than that of LCD screen, which makes it compatible with various black technologies, such as under-screen optical fingerprints, under-screen lenses, etc., while LCD screens do not support these functions due to special materials.

As for the future direction of smartphone appearance? It is estimated that no one can give a positive answer. But one thing is certain, mobile phones will not only become smarter, but also thinner and lighter, and the shape will also break through the traditional image.

OLED screen processing is convenient, high contrast, wider color gamut display, the previously criticized "strobe" problem has also been improved, combined with the above advantages, OLED is bound to become the focus of scientific researchers.

Compared with LCD screens, although OLED screens have the shortcomings of "hurting the eyes", its advantages are reflected in the thinness and lightness, outstanding color expression, and can bring users a more trendy experience, so now OLED screens are widely used in high-end machines. I believe that OLED screens can do better with time.

oled?organiclightemittingdisplay?i.e. organic light-emitting displays? It is a new rise in mobile phone LCD.

What kind of kind? It is known as the "dream display". Unlike traditional LCD displays, OLED display technology does not require a backlight and uses a very thin coating of organic materials and a glass substrate that emits light when an electric current passes through it. And.

OLED displays can be made lighter and thinner, with greater viewing angles and significant power savings.

At present, among the two major technical systems of OLED, low-molecule OLED technology is mastered by Japan, and high-polymer PLEDLG mobile phones.

The so-called OEL is this system, and the technology and patents are controlled by the British technology company CDT, which is compared to PLED products.

There are still difficulties in colorization. The low-molecular-weight OLED is easier to color, and not long ago Samsung released a 65530-color mobile phone O

led。However, in the future, OLED with better technology will replace LCD such as TFTHowever, organic light-emitting display technology still has a longevity.

Defects such as short life and difficulty in making the screen larger. At present, the main use of OLED is Samsung, such as the new SCHX339 uses 256

Colored OLED?As for OEL, it is mainly adopted by LG and we have seen it on its CU81808280.

The original text of OLED is organic light emitting diode, Chinese for organic light-emitting diode. Its principle is to sandwich an organic light-emitting layer between the two electrodes, and when the positive and negative electrons meet in this organic material, they will emit light, and its component structure is simpler than the currently popular TFT LCD, and the production cost is only about three to forty percent of the TFT LCD. In addition to the cheap production cost, OLED also has many advantages, such as the characteristics of self-light, at present, LCD needs a backlight module (add a lamp behind the LCD), but OLED will emit light by itself after power-on, which can save the weight and power consumption of the lamp (the power consumption of the lamp accounts for almost half of the entire LCD screen), not only so that the thickness of the product is only about two centimeters, the operating voltage is lower to 2 to 10 volts, plus the reaction time of OLED (less than 10ms) and color are better than TFT LCD is excellent, and it is also bendable, which makes it extremely versatile.

What is an OLED screen? What are the advantages?

Because there are many advantages, the effect is great. The advantages are:

1. Compared with the crystal layer of LED or LCD, the organic plastic layer of OLED is thinner, lighter and more flexible.

2. The light-emitting layer of OLED is relatively light, so its base layer can use flexible materials instead of rigid materials. The OLED base layer is made of plastic, while the LED and LCD base layer is made of glass.

3. OLED is brighter than LED, and the organic layer of OLED is much thinner than the corresponding inorganic crystal layer in LED, so the conductive layer and emission layer of OLED can adopt a multi-layer structure. In addition, LEDs and LCDs require glass as a support, and glass absorbs a portion of the light. OLEDs do not require the use of glass.

4. OLED does not need to use the backlight system in LCD. LCD works selectively blocking certain backlit areas to make the image visible, while OLED emits light on its own. Because OLEDs do not require a backlight system, they consume less power than an LCD (most of the power consumed by an LCD is used for a backlight system).

This is especially important for battery-powered devices, such as mobile**.

5. OLED is easier to manufacture and can also be made into larger sizes. OLED is made of plastic, so it can be made into a large sheet. It is much more difficult to use so many crystals and lay them out.

6. The field of view of OLED is very wide, up to about 170 degrees. LCDs, on the other hand, block light when they work, so there are natural obstacles to observation at certain angles. OLED itself emits light, so the field of view is also much wider.

OLED (OrganicLight-Emitting Diode), also known as organic laser display, organic electroluminescent semiconductor (OLED). OLED is a kind of current-type organic light-emitting device, which is a phenomenon that causes luminescence through the injection and recombination of carriers, and the luminous intensity is proportional to the injected current. Under the action of the electric field, the holes generated by the anode and the electrons generated by the cathode will move, and they will be injected into the hole transport layer and the electron transport layer respectively, and migrate to the light-emitting layer.

When the two meet in the light-emitting layer, an energy exciton is generated, which excites the light-emitting molecule and eventually produces visible light.

Because this technology is more adapted to the needs of contemporary people.

Emerging scientific and technological things have been developed step by step or step by step through the efforts made by people after understanding and mastering the objective laws of development.

This relies on the efforts of scientific researchers to benefit mankind.

Because the performance is better, it is a big improvement over LCD.

The lifespan of OLED displays is only 5000 hours, which cannot meet the needs of commercial OLED TVs, however, Seiko Aipu. The successful extension of the service life of the product to more than 50,000 hours can be regarded as a fundamental solution to the long-term problem of OLED life.

Samsung technology, TVs, and mobile phones are all in use.

OLED display has great advantages compared with the current LED display, it can be made thinner and supports flexible screen, can adapt to more environments, the main problem that plagued OLED display in the past is the life problem, generally only 5000 hours, which is far from meeting the needs of users, but now with the improvement of technology will be able to reach more than 50,000 hours, so that it can be promoted in large quantities.

Because a large number of OLED display devices will be used in the future, with the upgrading of technology, it will slowly replace the previous LCD, although the life is not as long as LCD, but the advantages are still obvious, now few people use a TV or mobile phone for seven or eight years, so it is enough, the advantage, relatively thin, or flexible to some equipment that needs thickness and thinness, a lot of space for use.

In other words, this OLED technology can fully replace the existing LED technology, so it will be the OLED era in the future.

Is there anything wrong with new technology replacing old technology?

OLED display technology is considered to be a display technology that is close to the ideal effect, and it is a substitute for the LCD liquid crystal display technology that is popular now. Therefore, to understand OLED display technology, we must understand the main differences between OLED display technology and LCD liquid crystal display technology. In fact, the topic of OLED replacing LCD is mainly referring to products that replace TFT-LCD technology with active drive.

Both are active drive technologies, and both use thin-film transistor circuit structures in the drive technology. However, due to the stage differences in the technical systems of the two, there are huge differences in the display performance, product technology, application conditions, and cost factors of OLED and LCD. It can be said that in terms of the main display indicators, OLED does not have that one that is lower than LCD products.

If you really want to find out some technical shortcomings, it is mainly reflected in the factor of life (the current service life of LCD is significantly higher than that of OLED products, which is the only advantage of LCD technology and OLED), but the life level of OLED is also constantly improving.

Second, in the product process, OLED technology has lower material consumption and fewer engineering steps. This is the most important reason why people believe that OLED will be an alternative technology for LCD. In addition to the material and process requirements are nearly 1 3 lower than those of LCD, the processing process of OLED is also much simpler than that of LCD.

According to relevant information, OLED display requires 86 Juefeng processing processes, while LCD screen requires more than 200 processes. First of all, in terms of display performance, OLED is much more perfect than LCD technology: it mainly includes OLED to achieve 3-5 times the contrast ratio of LCD, more than 40% of the color range of LCD technology, OLED has a perfect viewing angle experience, has a response speed of more than 1,000 times that of LCD, has higher brightness per unit power consumption, has a true black display effect, and has higher dynamic resolution under the same physical pixel density. One-third of the screen thickness of an LCD (OLED can theoretically make a TV set with a thickness of 1 mm).
