As the “top stream” of today’s LCD, Mini-LED backlight technology has been favored by major display manufacturers and users since the beginning of this year, and is regarded as the next generation mainstream display technology. Also as a high-end display technology, with the increase of the heat of Mini-LED display, it is inevitable to compete with OLED display.

Mini-LED is essentially a LCD screen, which is still composed of backlight module, liquid crystal layer, color filter and so on. The light emitting from the LCD screen mainly depends on the existence of the backlight module, which is composed of many lamp beads arranged in turn. Compared with the traditional backlight, the Mini-LED backlight technology reduces the size of each lamp bead to 50-200 microns. In this way, you can accept more lamp beads in the same size panel content, which has the advantage of greatly increasing the brightness of the screen display.

Not only that, with the increase in the number of panel lamp beads, more independent light control zones can be divided in the backlight module. The increase in the number of independent light control partitions enables the display to make more detailed local brightness adjustment, so that the screen has a higher display contrast. Moreover, because the Mini-LED backlight technology uses the direct backlight scheme, it can also avoid the common light leakage in the traditional LCD display.

Let’s take a look at OLED. In fact, we can see the obvious difference between them from the structure. The OLED panel itself is composed of a lot of organic light-emitting diodes and has the characteristic of self-luminescence. Based on this feature, OLED displays can display black images by turning off the corresponding pixels, so in theory, OLED panels can achieve infinitely high contrast.

If you compare the two, the Mini-LED backlight has more advantages in the brightness. At present, the mainstream Mini-LED display can generally achieve the peak brightness above 1000nits. At the same time, it also continues the strong durability of the LCD screen, which is more durable than the current OLED technology in terms of service life. However, in terms of disadvantages, like the traditional LCD screen, it uses liquid crystal deflection when presenting the black screen, so it can not be as pure black as the OLED display, but infinitely close to the black gray.

As mentioned earlier, the OLED panel can present a deeper pure black, and the screen color will look more transparent than the Mini-LED, thanks to its structural advantages. And when OLED carries on the color conversion, the electrode acts on the pixel directly, so it can achieve the gray-scale response speed of 0.1ms, which can not be achieved by the current LCD screen. There is no backlight module, so it can be done more thinly in appearance.

The disadvantage of OLED display is mainly reflected in the problem of short service life caused by “burning screen”. “Burning screen” means that after displaying a still picture for a long time, the screen will leave a residual shadow due to high temperature or pixel aging and other reasons. However, today’s OLED displays are equipped with a variety of anti-burn screen schemes such as pixel offset, and there is no need to worry too much about the service life.
