Currently on the market there are many models, TV designs are very diverse and diverse, so choosing a quality TV is also a problem quite a headache for consumers, because Modern televisions have a lot of parameters, the technology is very difficult to understand and if you do not know anything about technology then surely you do not understand what it is. Therefore, the article below will be sent to you about some aspects of television technology when you should buy and should not care.
SUHD technology TV will be better than UHD technology, the letter S in “SUHD“What is it and is HDR technology really better than 4K? What is the difference between technologies like 4K, HDR, OLED, UHD, SUHD, UHDBD and others or are they just different letters?
All of these symbols are terms that display technology that the television owns, to distinguish the technology on each product and certainly they have advantages or disadvantages.
1. HDR technology
HDR stands for High Dynamic Range, roughly translated as Dynamic range expansion. Is a new technology on the current TV for the ability to display color, brightness as well as higher contrast than conventional TVs.
HDR technology brings a lot of interesting things to the viewers, but the term is quite abused on televisions, so an alliance of film studios, broadcasters, technology companies has was established, they rated an HDR TV will be labeled UHD Premium, specifically for Sony TVs that do not use this label but instead they call it 4K HDR. Technically these two labels are the same, both for standard TV.
2. 4K and Ultra HD (UHD)
Basically 4K and UHD are the same, both are terms used describe high-resolution televisions Latest market today. For example, HDTV is only a TV with a resolution of 1920×1080 pixels, 4K and UHD are 4 times higher than HDTV, with a resolution of 3840×2160 pixels.
However, high resolution is not what determines the quality of a TV, it is just a small aspect needed in a television. Want a good quality TV you need to care about Good contrast ratio or accurate color gamut gives you the best TV experience.
3. What is local dimming?
This is the technology of making Local evening on TV but few people know it or know it well. Most TVs on the market today use LED backlighting on LCDs, and these backlighting are not able to turn off the display light in certain locations but can only be turned on or off.
LED Local dimming is different, this type of backlight is able to turn off completely at the places where the pixels display black. Turn off time is also very short, does not affect the image quality on your LCD. However, not all intermediate or premium TVs own Local dimming.
As mentioned above, the majority of TVs on the market are LED LCD Some models of LG use technology OLED – Organic Light-Emitting Diode (organic light-emitting diodes).
The OLED screen displays a deeper black color than the LED, the OLED pixels automatically emit light when electricity flows through it, so it saves electricity and low heat output. OLED displays provide good display quality, wider color gamut than LED, excellent contrast and extremely high scan frequency.
SUHD is a new UHD-based technology for high-end Samsung TVs that uses a new panel with a Nano Crystal color filter. Exclusive technology with good quality, safety with 3 layers of protection against damage, oxidation, does not contain toxic metal Cadmium.
In addition, SUHD possesses 64 times the color range of UHD TVs by using 10bit panels instead of 8bit panels, helping to reproduce more than 1 billion shades of color to make images more realistic and detailed than conventional UHD TVs. .
6. Quantum dots technology and Nano crystals
Quantum dots also known as Quantum dot technology, which allows LCD monitors to produce colors using color filters. Essentially these are tiny, green, and green plastic bands. The darker their color, the more realistic the image. Quantum dots are tiny particles that can emit a certain color, which is especially effective and they are added to the substrate of an LED TV or similar display. Quantum dots are really good at displaying colors, reproducing true colors but their cost is much higher and is used for high-end TVs.
And the Nano Crystals we mentioned above, is a proprietary technology on Samsung TVs, using 10bit panels to provide image quality, 64 times more colors than Ultra HD (UHD) technology .
7. Entertainment content standard 4K Blu-ray
By owning a TV with good quality, high resolution 4K, UHD or SUHD, surely you also need to have quality movies accompanying. Currently 4K quality movies are not uncommon but really not popular, current TV content still stops at HD. There are only a few services that provide 4K content like Netflix, Amazon or Vudu. In some LG TVs, when purchased, you will be provided with a month of free Netflix.
The current drawback is whether the data rate will meet the standard Blu-ray 4K movies, and instead you can also enjoy FullHD movie footage. With today’s TV technology, the fact that FullHD movies are up-scaled to 4K still provides good image display quality, not inferior to 4K movies.
