With the maturity of TV display technology,It is not difficult for us to find,Now the traditional LCD TV has become a thing of the past,More and more families are buying TVs,The goal is to put it onMini LED,But do you really understand those parameters and professional terms in the sales mouth?
So,This time, I'll talk to you about how to buyMini LEDTV,And some cutting-edge technologies of the current Mini LED TV,Let you not step on the pit in TV purchase。
First of all, let's be clear: Mini LEDs are positioned higher than traditional LCDs.
The advantage of Mini LED is that the backlight bulb of Mini LED is smaller, and compared with the side-entry backlight and direct backlight in the past, it achieves a more refined dynamic backlight effect, and the picture color detail and chiaroscuro are more excellent.
Therefore, Mini LED has a more delicate picture quality, clearer and more realistic picture effects, whether watching movies, playing games and daily use, Mini LED TVs can provide a more extreme visual experience.
Moreover,Not only compared with traditional LCD TVs,Compared withOLEDThe same is true,Especially in the three aspects of brightness、Color and service life,Mini LED advantages are very obvious,This is also an important reason why more and more TV manufacturers have begun to develop a large number of Mini LED product lines。
However, do you remember when you bought a Mini LED TV, how the sales said? It is nothing more than "compared with the traditional LCD, our partitions have reached XXX, and our brightness has reached XXXnits". But is the reality really that rosy?
The improvement of partition and brightness has an important impact on the light control and picture quality of Mini LED TV, but when this improvement reaches a certain level, its relative increase in efficiency will decrease a lot. So, beyond partitioning and brightness, what else do we need to focus on?
Here I would like to mention a noun "halo". If you've seen some low-priced Mini LED panel TVs, you'll find that when they display some chiaroscuro screens, there are often "halos" at the edges of the bright parts, which will affect the perception to a certain extent.
So, is there a way to solve the problem of "halo"? TCL has provided a full-link solution "global halo control technology". The reason why a "full link" term was added is mainly because "global halo control technology" is more like a complete set of solutions, which mainly solves the problems of Mini LED in five aspects: light emitting chip, lens technology, backlight algorithm, OD and screen, thus effectively solving the "halo" problem.
Light-emitting chips
At present, the "mainstream" Mini LED light-emitting chips are all single-core solutions, and there is no problem with emitting light, but the light control is somewhat meaningless.
The light-emitting chip of TCL's "global halo control technology" adopts six-crystal square core II. technology, which integrates six light-emitting cores on one chip, compared with the single-core solution, under the same area, it can well improve the luminous efficiency and energy efficiency, ensure that the light source itself is square, and fundamentally reduce the appearance of "halo".
Lens technology
After solving the problem of light-emitting chips, let's talk about lenses, that is, the "optical path" of light-emitting chips. GenerallyMini LEDTV uses mostly dispensing process,The curved surface is more conducive to the "scattering" of light,It is also a very important reason for cause"halo"。
TCL's "Global Halo Control Technology" improves the lens technology, using the "Lighthouse Light Control" optical image microlens, which adopts multiple arch bridge technology, which can more accurately achieve pixel-level light control, not only manages the optical path, but also improves the uniformity of the backlight, and reduces the formation of "halo" from the physical level.
Macro OD
In addition to the chip and lens, the halo formation has a lot to do with the OD distance, if you think it's not easy to understand, you can think about the scene when we hit the flashlight, is it that the farther the flashlight hits, the larger the final illuminated surface?
In fact, OD refers to the distance between the backlight panel of the TV screen and the diffusion plate, the smaller the OD value, the smaller the distance between the backlight panel and the diffusion plate, and the more focused the light-emitting surface, the more matching the size of the planned partition, the stronger the halo control ability, which is also an important reason why TCL's "global halo control technology" insists on doing macro OD.
Backlight algorithms
The hardware part is solved, then the software must also keep up.
Different from the "standard" backlight algorithm used by many manufacturers, TCL's "Global Halo Control Technology" integrates a number of self-developed light control algorithms, and on the basis of powerful hardware, thanks to excellent transient response and two-way 16bit high-end algorithm, the dynamic response of the picture is faster, and the halo control is more comfortable.
screen
After talking about the improvement of "halo" by "internal" technology, let's take a look at "external", that is, how the screen improves the "halo" problem. Compared with the traditional IPS hard screen, Mini LED TV can better play its advantages when paired with HVA screen, especially in terms of native contrast, high-end HVA screen can even reach 7000:1.
In addition,While ensuring high contrast,A layer of nano-level low reflection film has been added to the screen performance,The anti-light and anti-reflection effect of the screen is also improved compared with ordinary screens169%,So,TCL"Global halo control technology"Not only solves the problem of halo from the inside of the TV,And the outside has also found the current optimal solution,"Halo"The problem has been greatly improved。
Thanks to the improvement of the above five items one by one, the "global halo control technology" has achieved the first echelon of TCL's current Mini LED halo control, and at the same time, TCL behind this technology has received more attention, such as the new products they recently released: Q10K Pro, Q10K and T7K.
All three products are equipped with "Global Halo Control Technology", which solves the halo problem well. Take Q10K Pro as an example, the number of its backlight partitions has reached 5000+, coupled with up to 5000nits of ultra-high peak brightness and contrast, the picture display is not only accurate in color and rich in detail, but also obtains a more natural chiaroscuro.
Therefore, if you want to get a more extreme visual experience, TCL is equipped with "global halo control technology" TCL "Collector's flagship Mini LED TV" Q10K Pro is a very good choice.
