OLED VS Mini-LED What's the difference ?

There are significant differences in display technology between OLED and Mini-LED. These differences are mainly reflected in their definitions, display principles, scope of application, characteristics, advantages and disadvantages, etc. Here's a detailed comparison of the two:

1. Definition

OLED: OLED (Organic Light-Emitting Diode) is organic electroluminescence display technology. It is a current-type organic light-emitting device. Its light-emitting mechanism is to inject electrons and holes from the cathode and anode poles respectively. These electrons and holes are transported in the organic layer and recombine in the luminescent layer, thereby exciting the molecules in the luminescent layer to generate single-state excitons, and the single-state excitons radiate and attenuate. And glow.

Mini-LED: Mini-LED is an LED device with a chip size between 50~200μm. Mini-LED technology is precisely called Mini-LED backlight technology, which is mainly used as the backlight source of LCD.

2. Display principle

OLED: OLED uses self-luminous technology, that is, each pixel can emit light independently without the need for a backlight layer.

Mini-LED: Mini-LED is essentially LCD technology and needs to be equipped with a backlight. It reduces the size of LED lamp beads, accommodates more lamp beads on the panel, and achieves finer brightness adjustment through zoned backlight technology.

3. Scope of application

OLED: Due to its self-luminous properties, OLED performs well on small-screen devices (such as mobile phones, tablets, etc.). In addition, OLED also has greater imagination due to its flexible curved surface application scenarios.

Mini-LED: Mini-LED is suitable for various screens, especially large-size screens (such as TVs, billboards, display boards, etc.). Its features such as high brightness, high contrast and long life are particularly prominent on large-size screens.

4. Characteristics

OLED:

Extremely high contrast.

It has obvious advantages in refresh rate, pixel density, etc.

Flexible surface application scenarios have more room for imagination.

Thinner and more responsive.

Mini-LED:

High peak brightness.

Long life.

High definition and good picture quality.

The brightness of each area can be finely adjusted, and the light control effect is excellent.

5. Advantages and Disadvantages

OLED:

Advantages: good flexibility, wide viewing angle, thinner, fast response.

Disadvantages: relatively short lifespan, prone to screen burn-in, low yield in large sizes, and high cost.

Mini-LED:

Advantages: high brightness, long life, high definition, rich picture levels, and relatively affordable price (especially on large-size screens).

Disadvantages: Insufficient flexibility, response speed is not as fast as OLED; due to the integration of more backlight beads, the thickness is thicker and heat dissipation requirements are higher; halo phenomenon may occur in some cases.

To sum up, there are significant differences between OLED and Mini-LED in terms of definition, display principle, scope of application, characteristics, advantages and disadvantages. Which technology to choose mainly depends on the application scenario, budget, and requirements for display effect and lifespan.
