THX Certified 4K Display

THX Certified 4K Display

THX is a certification that is gained through both audio and video outputs via rigorous industry standard testing and has been an essential factor in the AV world for decades! 

THX Certified 4K Display

Even if you are unfamiliar with THX, you'll almost certainly be familiar with Star Wars creator George Lucas. Not long after the Star Wars trilogy hit the screens, Lucas began exploring how to get the best possible quality from what initially started as sound and audio, discovering that many cinemas couldn't cope with the intricacies and level of detail that his films contained.

Over the years this has developed into an integral testing process for both cinema, DVD, Blu-ray and now the world of Ultra-HD Televisions.

With these tests in mind, you can be safe in knowing that you are getting the ultimate Ultra HD experience from your Panasonic Smart TV. Here are a few varying factors that can add to the way you experience 4k and HD.

You may have come across the abbreviation THX, mainly if you are keeping your finger on the pulse of all things HD in the television and film world and perhaps wondered what it stands for. Over the last year or so, THX displays have started leaking their way into the Panasonic TV market, and we thought it was about time we shed some little light on what these displays are all about.

THX Certified 4K Display

Screen size

As displays grow in their physical size or our proximity to them is lessened, the decisive factors of higher resolutions such as 4K and HD start to become easier to identify. This is based merely on the number of pixels it takes to make up a display screen. A standard 1080p HD television has a total of approximately two million pixels which together display the on-screen image. This is true regardless of screen size, meaning that a 46-inch 1080p display and a 70-inch 1080p display both have approximately two million pixels. However, when you divide these two million pixels into the surface area for a 46-inch television, you end up with about 2,700 pixels per square inch. When you compute the same figure for a 70-inch TV, the number drops to approximately 1,780 pixels per square inch. In simplest terms, it is easier to see pixels on a larger screen than on a smaller screen because pixel is larger. The larger the screen, the more likely you’ll recognise the image clarity and sharpness benefits of Ultra HD displays.

Your eyesight, quality of the display itself, and various other factors influence the point at which a person can distinguish individual pixels on a screen of a given size. Nonetheless, for the overwhelming majority of consumers with a home television viewing distance of six feet or higher, the benefits of increased screen resolution will be recognised when viewing 4K content on a display 55 inches or larger.

FACTOR 2: Viewing Distance


On a 50-inch 1080p HD display, most viewers can begin to distinguish individual pixels only when standing within six feet of the screen. Therefore, if your viewing distance is 10 feet or higher, an Ultra HD 50-inch display will have little viewer benefit regarding image clarity and sharpness – which can be attributed directly to the increase in pixel count.

Whether you’re sitting closer or viewing content on a larger screen, once you’ve seen the crystal clear and lifelike quality of 4K pictures, it may be difficult to go back to watching content on a standard HDTV.

Panasonic and OLED


Panasonic's new OLED TV's have all the benefits of a THX certification, for approved crystal clear AV along with Panasonic's 'OLED' display. OLED is an organic 'light emitting diode' (much like a light bulb) which emits light in response to an electric current. While an LED backlight may illuminate the pixels in an ordinary LCD TV, each pixel in an OLED TV is its source of illumination. This ability to turn on & off individual pixels completely gives OLED TVs the upper hand in achieving the superior black level and contrast ratio, compared to LCD TVs.

Historically, many videophiles and cinema fanatics considered Plasma TVs to be the ultimate in experiencing a more life-like and realistic picture quality. Just as the phosphors in Plasma screen are used to create light, the OLED technology works in a similar way giving a wider viewing angle, improved brightness across the screen and overall improved picture quality – allowing you to enjoy the ultimate cinema experience at home.
