What is the difference between OLED display and amoled display?

There are significant differences between OLED displays and AMOLED displays in many aspects. The following is a point-by-point representation and summary of the differences between them:

Structure and basic principles:

OLED (Organic Light Emitting Diode) is an organic light-emitting diode, which is a solid-state organic semiconductor material. When an electric current passes through it, the organic material emits light.

AMOLED (Active-Matrix Organic Light Emitting Diode) is an active matrix organic light-emitting diode. It adds an "active matrix" structure to OLED, which includes thin film transistors (TFTs) as pixel drivers to achieve independent pixels. control.

Display effect:

AMOLED has higher pixel density, higher contrast and greater color saturation than traditional OLED screens. It enables more precise brightness and color control at the pixel level, delivering more vivid, lifelike image quality.

OLED screens can produce very deep blacks and bright whites because each pixel can emit light independently. This results in images with better contrast and richer detail in dark environments.

Energy efficiency:

AMOLED can turn off pixels when displaying black. Because OLED is self-illuminating, black pixels do not need to consume power. This makes AMOLED more energy-efficient than traditional liquid crystal displays (LCDs) and enables better contrast when displaying black.

The OLED screen itself has lower energy consumption and does not require a backlight, so it has lower energy consumption than LCD.

Flexibility:

AMOLED's thin film transistors are more flexible in structure, allowing them to create curved and flexible screens, resulting in more free and innovative designs.

OLED screens also have good flexibility due to their structural characteristics, especially when using flexible materials as substrates, which can be made into foldable displays.

Cost:

The manufacturing cost of AMOLED is relatively high because its manufacturing process requires more complex technology and equipment. But as technology advances and demand grows, costs are expected to gradually decrease.

Although the cost of OLED screens is gradually decreasing, in some specific fields, such as high-end mobile phones and TVs, the cost of OLED is still higher than that of some traditional LCD screens.

Practical applications:

Currently, most mainstream high-end mobile phones on the market use AMOLED screens. The AMOLED screen performs well in terms of high contrast and fast response, and is suitable for use in navigation, instrument panels and other scenarios.

OLED screens are more common in mid- to low-end mobile phones, and are also used in TVs, car infotainment systems and other fields. OLED screens are popular for their thinness, lightness, and power saving.

To sum up, there are obvious differences between OLED displays and AMOLED displays in terms of structure, display effect, energy efficiency, flexibility, cost and practical applications. Which display to choose depends on the specific application scenario and needs.
