What is OLED?

Welcome to visit our OLED category to check whether our products can meet your requirement.

OLED, also known as Organic Light Emitting Diode. This is a technology that achieves display through the electroluminescence phenomenon of organic materials. Specifically, OLED displays are composed of multiple layers of organic materials with electrodes sandwiched between them. When current passes through, electrons and holes in the organic material layer combine and release energy, which is emitted in the form of photons, producing visible light.

OLED has a series of significant characteristics and advantages:
1.Self luminous characteristics:
Unlike display technologies such as LCD that require a backlight source, each pixel of OLED can emit light independently, which makes it more pure in black performance and higher in contrast.
2.Wide viewing angle:
OLED screens have a very wide viewing angle, almost from any angle, with consistent color and brightness, and no color distortion or brightness decrease.
3.Quick response:
OLED has a very fast response time and can almost immediately display image changes, which gives it an advantage in dynamic image display, such as smoother visuals when watching sports games or playing video games.
4.Energy saving and environmental protection:
Due to OLED’s self illumination, the brightness of each pixel can be precisely controlled, achieving a more energy-efficient effect. Meanwhile, it do not require backlighting, making them lighter and thinner compared to LCD screens.
5.Flexible Display:
OLED materials have flexibility and can be used to produce flexible or foldable display screens, providing unlimited possibilities for the development of future display technology.

Currently, OLED technology has been widely applied in consumer electronics products such as smartphones, televisions, and tablets. With the continuous advancement of technology, the application range of it will become increasingly widespread, and we have reason to expect it to bring more innovation and surprises in the future. mainly including:
1.Business field:
Small OLED screens can be installed on POS machines, copiers, and ATMs due to their advantages of flexibility, lightweight, strong anti-aging, aesthetics, and practicality. OLEDs with large screens can be used as commercial promotional screens or advertising screens at stations and airports because it have a wide viewing angle, high brightness, bright colors, and much better visual effects than LCD screens.
2.Electronic products field:
OLED is most widely used in smartphones, followed by laptops, displays, televisions, tablets, digital cameras, and other fields. OLED displays, due to their self luminous properties, can achieve better color performance, higher contrast, and wider viewing angles, making OLED TVs, displays, and other products favored by consumers.
3.Transportation field:
OLED has a wide range of applications in the transportation field due to its wide viewing angle performance, such as ship and aircraft instruments, GPS, video phone, car display screens, etc.
Even without direct eye contact, you can still see the screen content clearly.
4.Industrial application field:
OLED is also suitable for industrial application fields, such as instruments and meters, because it is an all solid, non vacuum device with characteristics such as shock resistance and low temperature resistance (-40 ℃~+80 ℃). It has also been very important in military applications, such as being used as a display terminal for modern weapons such as tanks and airplanes.
In addition, It also has the characteristic of flexibility, which can be widely used in various curved design products, such as curved TVs, intelligent wearable devices, etc. Meanwhile, different OLED technologies such as transparent screens, top emitting OLEDs, and foldable OLEDs are constantly expanding their application areas.
With the continuous development of technology, the application fields of OLED will further expand.
