A UHD or 4k ultra HD TV is of the advanced technology and considered to be the best picture quality TV between the various television technologies. You will generally find the 4k ultra HD TV models in 40 inches or more than 40 inches. This is because to really appreciate the higher picture quality you need to watch it on the large TV, as it's rather lost on the small screen. A 4k HD TV simply boosts the picture count and the resolution and it usually refers to the resolution of 3840 x 2160 that's nearly four times larger than the 1080p, hence the term 4k. The more pixels there are, the more details the picture contains. The term 4k ultra HD is not just about the resolution but the technology allows for a higher frame and better color replication to give a more true-to-life image. 4k is obviously much sharper than the 1080p. In the space that a 1080p TV holds a pixel, 4k TV on the same size can hold four that makes for a significant jump for quality. Here are some
Before knowing the difference between the LED and LCD TV’s , it is very important to know how they work. What Is An LCD? LCD is an abbreviation for Liquid Crystal Display, LCD is a tube based technology facilitate a high definition picture with a very thin screen, and had derived as the empathic high definition technology. Apart from the Television LCD also enable mobile, tablets and computers systems. Liquid Crystal Display uses either a passive matrix or an active matrix display grid. An active matrix has a transistor located at each pixel intersection, requiring less control luminance of a pixel. LCD comes into 2 segmentation – IPS (In-Plane Switching) and TFT (Thin Film Transistor). TFT is characterized as an active matrix LCDs, which means that they can cumulatively retain pixels on the screen while also addressing other pixels using the minimum amount of the energy. On the other hand, IPS technology is an improvement on traditional TFT display module in the sense
