When we browse the stores, we will find that there are many different terms, such as “LED,” “LCD,” “OLED”, and “QLED.” These terms are so confusing, and they make it more challenging to choose which should be the best products. This article mainly focuses on MiniLED.
MiniLED Definition:
MiniLED is a type of LCD, and MiniLED only changes the backlight types from some light strips(DLED/ELED) to thousands of single digital light dots. These light bulbs are arranged in “areas/zones” so they can be controlled locally to be turned off or turned off. The technology of dynamically turning on and off zones is also called “local dimming.” Samsung’s Neo QLED is also a MiniLED TV.
Do Not Be Fooled! MiniLED Is Just An LCD!!!
LCD means liquid crystal display. The liquid crystals are twisted by electricity so they can let the lights go. Below is an example of an LCD structure. This structure is thick, resulting in a thick back cabinet of an LCD TV. It’s the same as Mini LED. OLED structure is more straightforward than the LCD structure, and you can see a thin OLED TV in a retail store.
REMIX THE BACKLIGHTS TO MINI-LEDS
TFT-LCD Structure contains 2 glass substrates, 2 polarizers, 2 electrodes, and an RGB color filter. How backlights are arranged in the back cabinet defines the names of a TV. For example, ELED(edge) only puts the light strips at the edge of TVs. ELED is commercial, but the edge backlight provides insufficient brightness for a larger screen. DLED(direct) puts the light strips like a 2-D array horizontally and vertically at the back. The MINI LED technology is like an upgrade of DLED. Instead, thousands of mini-LED nodes are put at the back of TVs. These mini-LED nodes provide better brightness because they can fill up almost all the gaps compared to DLED. Meanwhile, these mini-LED nodes are controllable with the function of local dimming. Depending on how the algorithms are set up, the nodes can be divided into different “zones.” More “zones” mean better local dimming, which can simulate the same contrast level of an OLED TV.
Is It A Good Choice To Buy A MiniLED TV?
The answer depends on what environment you choose to use the TV. Since MiniLED technology only increases the contrast ratio compared to the traditional LED TV, MiniLED is just LCD-based. If the room where the TV will be placed has a good environment light source, then the normal LCD is enough. A MiniLED or an OLED TV is better if you pursue a cinema-quality dark environment. We can feel an apparent contrast-ratio effect if the room is dark.
Backlighting Technology:
Mini-LED: Mini-LED TVs use a large number of miniaturized LEDs for backlighting. These LEDs are smaller than those used in traditional LED-backlit LCD TVs.
LCD: Traditional LED-backlit LCD TVs use a backlight behind the LCD panel to illuminate the pixels. LED-backlit can be DLED(direct LED), ELED(edge LED).
OLED: OLED TVs do not have a “backlight” structure. OLED is a structure of “electroluminescence”. Each pixel can illuminate itself.
Local Dimming:
Mini-LED: One of the advantages of mini-LED technology is that it allows for more precise local dimming. Local dimming involves adjusting the brightness of individual zones of LEDs independently, enhancing contrast and black levels.
LCD: LCD TVs with traditional LED backlighting also employ local dimming, but mini-LED allows for more dimming zones, which can result in better control over the backlight.
OLED: OLED TVs has pixel-level local dimming because each pixel illuminate itself.
Picture Quality:
Mini-LED: Mini-LED TVs aim to provide improved contrast ratios, deeper blacks, and better HDR (High Dynamic Range) performance than traditional LED-backlit LCD TVs.
LCD: Traditional LCD TVs can sometimes suffer from limited contrast ratios and black levels, especially compared to OLED displays.
OLED: OLED has an average better performance than mini-LED and LCD TVs. The contrast ratios contributing to local dimming help OLED TVs win over the other 2 types of TVs. On the other hand, the light emitted from organic material is better than white LED in a traditional LCD TV. It covers more cover length.
Cost:
LCD: LCD TV technology is currently a relatively complete technology. A LCD TV price is lower than Mini-LED TVs and OLED TVs.
Mini-LED: The Mini-LED TVs are based on an upgrade of backlight technology. The cost difference between LCD and Mini-LED is the cost of miniaturized LEDs and local dimming control to the motherboard. It is more expensive than an LCD TV but won’t do too much.
OLED: Much more expensive than LCD and mini-LED TV due to the organic material and its production technology. Check the article here to understand why it is more expensive.
Conclusion:
As an intermediate product from LCD TV to OLED TV, miniled TV does have its unique features. First of all, its backlight bulbs are several times, or even a hundred times, more than those of a conventional TV. If it is a high-end miniled TV, it has thousands of backlights; in addition, it obtains a certain degree of local dimming through a technology called backlight zone control. For example, a miniled TV claims that it has 4320 bulbs, and there are 1080 Zone, then it treats the 4 bulbs as a separate controllable area. This technology can catch up with the display effect of OLED to a certain extent. But it is worth noting that every pixel of an OLED TV emits light, so there are 3840*2160=8294400 individually adjustable light bulbs in a 4k OLED TV, which are also “areas”. Looking at it this way, unless miniLED can also achieve pixel-level backlighting, it will not be able to catch up with the local dimming effect of OLED. In addition, the cost of miniled will be a little more expensive than ordinary LCD TVs, because the number of light bulbs and a motherboard responsible for controlling local dimming will increase the cost a lot. If you want to try a high-brightness LCD TV, miniled is a good choice.
