OLED, short for organic light-emitting diode, is an emerging display technology. It uses mechanical, thermal, chemical and other methods to make thin films of organic compounds and metal materials, and controls these materials through voltage to achieve a luminous effect. OLED can be widely used in display, lighting, information storage, detectors, sensors and other fields. At present, OLED has become an important development direction of display technology. The following is a detailed introduction to OLED.

 

1. Various characteristics of OLED

 

1. Strong contrast

When compared to LCD, OLED has a stronger contrast ratio, which is caused by the difference between the amount of light emitted by the OLED's light-emitting material and the amount of light absorbed by the black ink. Therefore, OLED pictures are more vivid and realistic, and the picture is clearer.

 

2. High brightness and color saturation

OLEDs can produce very bright colors because the luminescent material emits the color itself without the need for a backlight source to increase its brightness or saturation. This advantage makes OLED ideal for high-quality image displays, whether for mobile devices or high-resolution televisions.

 

3. Fast response speed

OLEDs can respond quickly due to the thin structure of organic thin-film light-emitting diodes, the symbol for OLEDs, and the absence of liquid crystal panels and lighting elements. This makes OLED respond quickly and enhances the performance and playback effect of dynamic pictures.

 

4. Wide viewing angle

OLED's wide viewing angle means excellent optical performance for both home theaters and public spaces. This allows viewers to have a better viewing experience with better image detail and clarity. In addition, high-end mobile devices use OLED to produce better visual effects and viewing experience.

 

5. Energy saving

The latest version of OLED has very good energy efficiency and green environmental protection characteristics. Because it doesn't require reflectors or backlights like LCD monitors and televisions, it uses less energy. Since no backlight is required, low-brightness PM OLED displays consume almost zero power. This is very beneficial for the battery life of mobile phones and other portable devices.

 

2. OLED types and their applications

 

1. Universal OLED

This type of OLED can handle many different types of images, from general commercial applications to home entertainment. This kind of OLED can provide impressive colors and contrast ratios and is the most common and popular OLED application.

 

2. Maternal and infant OLED

The main application of maternal and infant OLED is in hospitals. This kind of OLED can provide the most basic physiological data for the observation of babies. These devices can display information such as temperature and heart rate, and have some other basic measurement and promotional functions.

 

3. Wearable OLED

Wearable technology has recently become the technology of choice for many smartwatches and head-mounted displays. This OLED could provide better color coordination and larger screen sizes for smartwatches and other devices. Due to the excellent characteristics of OLED, there is more potential for use in this field.

 

4. Special function OLED

This type of OLED is commonly used in various custom applications such as gaming, robotics, drone control applications, etc. These devices often need to be customized for a specific target audience and can offer highly specialized colors and fonts.

 

3. The future of OLED

 

There is no doubt that OLED is one of the key technologies for future displays. Due to its excellent image display capabilities, strong contrast and color saturation, it has become the choice of more companies. OLED will also become a key technology in other areas such as lighting, detectors and sensors. OLEDS will have a wide range of applications in the future, and we can look forward to seeing more and better OLED products emerge. Make our life and work more efficient and convenient.
