LCD HD flat screen TV
Samsung adds a Touch of Color to a blazing-fast 4ms response time and rich connectivity features to redefine the role HDTVs play in the home with its forward-looking Series 6 (A650) LCD HD flat screen TV and its Series 7 (A750) flat screen LCD HDTV. Utilizing the award-winning technologies found in all Samsung flat screen HDTVs, Series 6 and 7 HDTVs deliver unparalleled picture quality and enhanced connectivity and networking capabilities that create a true entertainment hub for any home. Series 7 takes networking and multimedia management to a whole new level. Consumers can easily enjoy MPEG and JPEG files stored on external devices by connecting through a side-mounted USB 2.0, turning their flat screen LCD TV into a full-scale home viewing gallery, or connect their MP3 players for a dynamic audio experience.
home appliances
A major appliance, or domestic appliance, is usually defined as a large machine which accomplishes some routine housekeeping task, which includes purposes such as cooking, food preservation, or cleaning, whether in a household, institutional, commercial or industrial setting. An appliance is differentiated from a plumbing fixture because it uses an energy input for its operation other than water, generally using electricity or natural gas/propane. An object run by a watermill would also be considered an appliance. The term white goods or whiteware [1]is also used for these items, primarily where British English is spoken, although definitions for the term "white goods" can differ. In the United States, the term white goods more commonly refers to linens rather than appliances.[2]
Major appliances are differentiated from small appliances because they are large, difficult to move, and generally fixed in place to some extent. They are often considered fixtures and part of real estate and as such they are often supplied to tenants as part of otherwise unfurnished rental properties. Another frequent characteristic of major appliances is that they may have substantial electricity requirements that necessitate special electrical wiring to supply higher current than standard electrical outlets can deliver. This limits where they can be placed in a home.
Major appliances have become more technically complex from the control side recently with the introduction of the various Energy Labelling rules across the world. This has meant that the appliances have been forced to become more and more efficient leading to more accurate controllers in order to meet the regulations.

How To Pick Your Best TV Type?
Several important factors determine the quality of your HDTV picture. So how do you find a picture you like?
* TV TECHNOLOGY
As you probably already know, there are several TV technologies available. LCD televisions are thin and lightweight with a high-quality picture, even in brightly lit rooms. Plasma screens are heavier than LCDs but may deliver a slightly picture in dark rooms with more intense colors. DLP TVs offer brilliant screens, but are thicker than LCDs or Plasma.
* RESOLUTION
Think about TV resolution as the number of pixels contained in one "frame" of a television show or movie. More pixels in each frame will give you better picture detail. 720P and 1080P are the two most common resolution standards for HDTV now. With about 1 million pixels in each frame, 720P provides a vivid, high definition picture. 1080P offers the highest level of HDTV quality with over 2 million pixels in each frame, creating even greater picture details. While broadcast is mostly limited to 720P, 1080P is the standard for high definition disc players like Blu-Ray.
* CONTRAST RATIO
Contrast ratio is a number that measures the difference in light intensity between the brightest white and the darkest black on the screen. In general the higher the contrast ratio number, the better the image quality. Most times, you will find Dynamic Contrast Ratio specified, but be sure you are comparing the same type of contrast ratio.
* CONTRAST ENHANCEMENT
Another way to improve contrast ratio is with contrast enhancement technology. Most of the time, this uses back lighting to improve apparent contrast. This is especially helpful in dark rooms, as it helps your eyes adjust to the best light levels. This dynamically improves contrast, resulting in deep blacks in darker scenes without losing fine details in shadows and other dark areas of the picture.
* BIT COLOR
Another important contributor to picture quality is what is called "bit depth". This is the size of the number that is used to assign colors on the screen. The higher the number, the more displayable colors will appear (see the image below). Of course this is only true if both the display processor and the panel support that number of bits!
