Our next subject is a technology that is changing the way we watch our media. The OLED panel uses cutting edge technology; physically changing the way the image is produced. First off, lets get to what it stands for. OLED is an Organic Light Emitting Diode. We are all familiar with the Light Emitting Diode part of the new TV (LED) but what makes the pixel organic? In fact, how is the word “organic” being used to describe the TV? To describe OLED, we must mention “LED” panels. While the backlighting is LED, the front panel is still an LCD screen. Panel manufacturers then put sub-panels between these two pieces, giving you features like HDR. For this reason, LED TV’s will always be thicker, with a more pronounced physical form. High end LED TV’s will have a full-array of LED’s, giving that TV the ability to shut off certain zones creating a more dynamic contrast, and greater color. Motion rate will be a blog all on its own! The OLED TV is built in a completely different way. It uses special coatings of organic compounds that are arranged in such a way that so when an electric current is sent through it, it illuminates. In order to create black levels, those pixels simply shut off. Because of these features, Plasma TV lovers, look no further! The color, contrast and motion rate (and everything in-between) is truly a sight to be seen. Come by our showroom to experience the latest and greatest audio/video technology available!
What’s the Deal with 4K?
The topic I want to discuss today is probably the most basic of all the questions out there; what is 4K? First, 4K and UHD are synonymous. There is no difference between the two as they mean the same thing! 4K or UHD (Ultra High Definition) refers to how many vertical and horizontal lines or “rows” of pixels a TV has. A pixel is a small dot on the front panel of the television that together with the other pixels, make up the image on the screen. The more tightly packed the pixels are, the greater the resolution. A 4K TV typically has 3840(vertical lines of resolution) x 2160(horizontal lines of resolution). This gives you a little over 8 million effective pixels on a 4K TV. Obviously this number changes based on the size of your TV, but the proportions and ratios are always consistent; the pixels per square inch will never change. In comparison, the “Full HD” or 1080 resolution was the highest TV resolution available to the consumer just a few yeas ago. That TV had 1920(vertical lines of resolution) x 1080(horizontal lines of resolution). This totals a little over 2 million pixels. A Full High Definition TV has 2 million pixels, the Ultra High Definition has 8 millions pixels. Eight divided by two… 4! 4K was born and has been taking the world by storm ever since.
Welcome to the JS Audio Video Blog!
By now, you must have heard of at least some of these buzzwords high-end electronic manufactures are using in their advertising. 4K UHD, HDR, OLED, 10-bit panels, quad-core processors, 4:4:4 color, and so many more. But what do they all mean? Better yet, what do they mean to the person who either wants to invest in a whole home automation system, or the person who just wants an amazing picture, stunning audio and an easy way to control everything? In the next few blog posts, I am going to explain the in’s and out’s of most of these features and how they affect the ever evolving world of technology we all seem to find ourselves in. Being informed on these new technologies is going to help you make a smarter buying decision, which you won’t regret in the long run.
