What is OLED display?

OLED display is an advanced display technology, and its full name is "Organic Light-Emitting Diode". The following is a detailed introduction to OLED display:

 

  1. Basic Principle

The OLED display principle is fundamentally different from traditional LCD technology. It mainly relies on electric field drive to enable organic semiconductor materials and luminescent materials to emit light after carrier injection and recombination. Specifically, the ITO glass transparent electrode is used as the device anode, and the metal electrode is used as the cathode. The power source drives the electrons to be transferred from the cathode to the electron transport layer, and the holes are injected from the anode to the hole transport layer, and then migrate to the luminescent layer. After the two meet, excitons are generated, which excite the luminescent molecules and generate light sources after radiation.

  1. Main features

Low power consumption: OLED does not require a backlight, so it is more energy-efficient than LCD technology.

Light weight of finished product: OLED screens use organic materials, have a small mass, and a high shock resistance coefficient.

Large screen viewing angle: OLED has a wide field of view, usually up to about 170 degrees.

Fast response speed: The response time of OLED is only at the microsecond level, which is much faster than LCD screens.

Thin and light: OLED's organic plastic layer is thinner, lighter, and more flexible.

  1. Advantages and Disadvantages

Advantages

High image quality: High contrast, wide color gamut, and fast response time, can present delicate and realistic images and video effects.

Wide application: OLED technology is widely used in TVs, mobile phones, tablets, automotive displays, digital advertising, medical equipment and other fields.

Bendable: OLED screens can be bent, providing more possibilities for product design.

Disadvantages

Short service life: OLED organic materials have a limited lifespan, usually only 5,000 hours.

High production cost: OLED panels are difficult to produce, resulting in relatively expensive prices.

Insufficient color purity: OLED is not easy to display bright and rich colors.

Easy to burn in: OLED screens flicker at low brightness and are prone to burn in after long-term use.

 

  1. Application fields

TVs and displays: OLED TVs and displays are widely used in home entertainment and professional fields.

Mobile devices: OLED screens are widely used in mobile devices such as smartphones, tablets, and wearable devices.

Automotive display: OLED technology is used in the automotive field for in-vehicle displays, dashboards, and interior lighting.

Digital advertising: The transparency and flexibility of OLED screens make them ideal for digital advertising.

Medical equipment: OLED screens are used in medical equipment such as surgical instruments, monitors, and diagnostic equipment.

In summary, OLED displays have broad application prospects in various fields with their unique characteristics and advantages. With the continuous development and innovation of technology, the application areas of OLED displays will continue to expand.
