What is an OLED screen?

OLED (Organic Light Emitting Diode) screen is a display screen manufactured using organic light emitting diode technology. It consists of a series of thin films of organic material that emit light and are able to emit light when an electric current is passed through it.

OLED screens, unlike traditional liquid crystal displays (LCDs), do not require a backlight. Each pixel is an independent light-emitting element that can be independently illuminated or turned off as needed, which means that OLED screens can achieve true pixel-level high contrast and color performance.

Here are some of the characteristics of OLED screens:

Color performance: OLED screens are capable of producing very vivid, lifelike, and detailed colors. They feature a wide color gamut and accurate color reproduction for true-to-life images and videos.

Contrast Ratio: Since each pixel of OLED screens can be turned on or off independently, they can achieve very high contrast ratios. True blacks can be achieved when the pixels are turned off, delivering deep blacks and detailed shadows.

Response time: OLED screens have a fast response time and are able to quickly switch the state of pixels for smooth moving images and videos.

Thin and flexible: The material of OLED screens is flexible, so very thin and flexible screens can be manufactured. This makes them promising for a wide range of applications in bendable and foldable devices.

OLED screens are used in a wide variety of devices, including smartphones, tablets, TVs, digital watches, and other portable devices. They are popular for their excellent color performance, high contrast ratio, and thin and flexible features, bringing users a better visual experience.

Which is better, OLED or LED?

Both OLED and LED are different display technologies, each with its own advantages and applicable scenarios. Here are some comparisons of them:

Advantages of OLEDs:

Color performance: OLED screens can present more vivid, realistic and delicate colors, with a wide color gamut and accurate color reproduction capabilities.
Contrast: OLED screens can achieve true blacks and high contrast, delivering deep blacks and detailed shadows.
Viewing angle: OLED screens have a wider range of viewing angles, making images look better at different angles.
Response time: OLED screens have a fast response time, enabling smooth moving images and videos.
Thin and flexible: OLED screens can make very thin and flexible screens for bendable and foldable devices.

Advantages of LEDs:

Brightness: LED displays can provide high-brightness display effects, suitable for outdoor environments or applications that require high brightness.
Economical: LED technology is relatively mature and the manufacturing cost is low, suitable for large-scale display screen applications. How much is the LED billboard?
Lifespan: The LED display has a long lifespan and can continue to run stably for a long time.

Which is better, OLED or AMOLED?

Both OLED (Organic Light Emitting Diode) and AMOLED (Active Matrix Organic Light Emitting Diode) are display screens manufactured using organic light emitting diode technology, and there are some differences between them. Here’s a comparison of them:

Advantages of AMOLED:

Contrast: AMOLED screens have higher contrast than traditional OLED screens, enabling deeper blacks and richer color levels.
Energy saving: AMOLED screen adopts active matrix drive technology, only the activated pixels will consume power, no additional backlight is needed, so it can save energy when displaying black and dark content.
Viewing angle: The AMOLED screen has a wide viewing angle range, which makes the viewing effect of the image better at different angles.
Response time: The AMOLED screen has a fast response time, enabling smooth moving images and videos.

Advantages of OLEDs:

Color performance: Traditional OLED screens can present more vivid, realistic and delicate colors, with a wide color gamut and accurate color reproduction capabilities.
Thin and flexible: Traditional OLED screens can make very thin and flexible screens, suitable for bendable and foldable devices.
