Understand the four display technologies of LCD, OLED, Mini LED, and Micro LED in one article


Latest company news about Understand the four display technologies of LCD, OLED, Mini LED, and Micro LED in one article

According to their respective characteristics, these screens can be roughly divided into four types: LCD, OLED, Mini LED, and Micro LED. Among these four types of screens, the Mini LED can be said to have caught everyone's attention in the past two years. In this article, the editor will take you to a brief understanding of these four display technologies.
1、 Backlight and direct display
A display screen is composed of multiple pixels, and the technologies mentioned above, such as LCD, OLED, Mini LED, and Micro LED, can be divided into two types based on the light emitting principle of these pixels: direct display and backlight: each pixel directly emits its own light, which is commonly referred to as direct display; The light generated by a refracted light source, which is then reflected back to the human eye, forming this pixel, is called backlight. Below, we will deepen this understanding by using the typical scheme of backlight and direct display of Mini LED.
1. What is Mini LED?
First of all, let me briefly review what Mini LED is. Mini LED, also known as "sub millimeter light-emitting diode", has a chip size between 50 and 200 μ The size of LED devices between m is between small spacing LEDs and MicroLEDs, which is the result of further refinement of small spacing LEDs. Mini/MicroLED is a product of the refined development of LED displays, and as the technological path becomes clearer, it will become a new blue ocean for LED display applications.

Compared with the current mainstream display technology LCD, Mini LED has better display performance, an order of magnitude increase in response speed, and the screen can be lighter and thinner. With a significant reduction in power consumption, it can extend battery life.
Compared with OLED displays, MiniLED maintains excellent display performance and flexibility, resulting in faster response speed and higher high-temperature reliability. The important feature of Mini LED compared to small pitch LED is its de encapsulation, mainly targeting the high-end small pitch LED market, which can achieve higher resolution and display effects.
2. Differences between backlight and direct display from different Mini LED schemes
MiniLED for backlighting is essentially an LCD, and direct display uses MiniLED to directly display graphics. By controlling the direction of the liquid crystal molecules through the LCD board circuit, the backlight (different colors) is projected onto the display screen.

3. Mini LED
Mini LED miniaturizes the LED beads on the backlight layer of the LCD screen, with each LED bead size approximately 50-200 μ Between m, this way the backlight layer can accommodate more backlight beads, allowing the screen to achieve better brightness and brightness uniformity. Mini LED divides the backlight layer into small pieces and dims it through LED chips, thereby improving the black and white contrast problem that LCD has long been criticized for. It can achieve a display effect similar to OLED and avoid issues such as lifespan.

4. Micro LED
Micro LED can be said to integrate all the advantages of LCD and OLED, with significant advantages such as high image quality, low energy consumption, and long service life. However, the manufacturing process is difficult and the production cost is high.
