What is a mini LED? What is the difference between MicroLED, OLED and AMOLED?

You have to imagine how much technology is behind the many screens we use in our daily life, such as smartphones, tablets, smart watches and TVs, you must have heard of LCD, LED, OLED, QLED and microLed, and now miniLed is here.

What is a mini LED?

As the name suggests, the display Mini LED With micro-backlights, there can be over a thousand local dimming zones (compared to hundreds for LEDs), amplifying contrast.

Advantages of miniLED:

  • higher contrast;
  • Glows more in the dark;
  • energy saving;
  • They use inorganic gallium nitride (GaN), which keeps them from degrading over time like OLEDs, extending the life of the device.

What is the difference between miniLED and microLED?

Micro LED is an evolution OLEDusing smaller, brighter individual red, green and blue LEDs (traditional RGB colors) to emit colored light directly.

Each pixel produces its own light through microLEDs, and miniLEDs still use the overall LCD matrix to filter the backlight, just more accurately than traditional LCDs.

What is an LED screen?

Screen lead The working principle is the same as the LCD monitor. The difference is the light source used to illuminate the screen.

Instead of fluorescent lights, they use multiple LEDs (led) white, low power consumption. This technology allows for thinner screens that use “pure” light, resulting in better color fidelity.

Because lighting is done by multiple LEDs rather than a single light source, manufacturers can divide them into “zones” and control the light intensity of each zone.

LED screens are by far the most common in TV sets and are also used in laptops, smartphones and tablets.

What is OLED?

OLED is an acronym that stands for “Organic Light Emitting Diode“.

Essentially, it consists of a “grid” of dots formed by organic compounds that emit light in response to an electrical current. Different compounds produce different primary colors (RGB), which combine to allow the panel to reproduce any desired color.

Like microLEDs, each point generates its own light, eliminating the need for screen lighting and filters. They are very thin canvases known for their high contrast and vibrant colors. With their flexible substrates, they’re perfect for folding devices like Samsung’s Galaxy Z Fold series.

What is an AMOLED screen?

name AMOLED method Active Matrix Organic Light Emitting Diodes Or Diodes’ Active-Matrix Organic Light Emission, an OLED-based technology.

OLED pixels are connected to thin-film transistors (called TFTs, or thin-film transistors).

TFTs are capable of depositing a small thin film that is active and has various semiconductor, insulator, and metal contacts. All of this is built on one support: glass. It organizes itself and forms a matrix with multiple pixels that are electrically activated or not emit light.

This involves a series of functions that order pixels by telling them how each should light up and function. AMOLED screens have four layers: an anode, an organic layer, a cathode, and another layer, with circuits capable of turning pixels on and off three times faster than other common circuits.
