Samsung and 3-D TV warning labels are making some consumers think twice about buying a new 3D television.
Samsung and 3-D TV warning for kids, teenagers, pregnant women, and the elder. The futuristic 3D television sets can actually cause health problems. The warning labels suggest that children and teenagers are more susceptible.
3-D TV viewers may experience an epileptic seizure or stroke. This can happen when they are exposed to certain flashing images or lights contained in TV pictures or video games. If you suffer from or have a family history of epilepsy or strokes, then consult with a physician before using the 3D function.
One of the most interesting health warnings points out the use of alcohol. Those under the influence of alcohol should avoid using the 3-D functionality. In addition, viewers who are sleep-deprived should also avoid the new 3D televisions.
Pregnant women and elderly people should also avoid 3-D TVs. People should stop using the function if they experience dizziness or involuntary eye movements. Other symptoms include nausea, convulsions, or disorientation.
3D Glasses May Cause Headaches
Watching TV while wearing 3D glasses for an extended period of time may cause headaches or fatigue. If you have a headache, fatigue or dizziness, stop viewing TV. Consumers are asked not to the 3D glasses for any other purpose other than viewing 3D television.
When watching the television at home, consumers are encouraged to block sources of direct sunlight. Fluorescent lighting may cause a flickering effect by altering the operation of the 3D glasses. Just when you think the new TVs were great, consumers now have to think twice about buying a 3-D television set.
LED, LCD, Plasma
LEDs offer an ultra-slim design and are power efficient With mega contrast ratios and advanced internet connectivity features, these are some of the best television sets ever. LCDs promise sharp, detailed images, smooth motion quality, and exclusive Touch of Color design. Plasma TVs create amazing pictures with excellent action scenes and the deepest blacks and brightest whites on the screen.
The market might be ready for this new high-tech era because 3D movie theaters are widely successful. Panasonic’s 3D televisions are a critical part of the Japanese electronics giant’s strategy to reverse television losses. It suffered financial losses and was in the red last year.
The push to bring three-dimension viewing into the living room comes with the wave of 3-D movie theaters. Last weekend, “Alice in Wonderland” grossed an estimated $116.2 million at the box office, beating the first-weekend receipts of “Avatar.”
Realistic Three-Dimensional Field
A 3D television is a television that employs techniques of 3D presentation. These techniques include stereoscopic capture, and multi-view capture, with a full 3D display. It is also known as a special viewing device to project a program into a realistic three-dimensional field.
3D-ready sets are those that can operate in a 3D mode in conjunction with LCD shutter glasses. The television tells the glasses which eye should see the image being exhibited at any given moment. It does this by creating a stereoscopic image.
The television sets usually support HDMI 1.4 and a minimum refresh rate of 120Hz. In fact, Samsung utilizes DLP technology from Texas Instruments. As of January 2010, Toshiba, Samsung, Sony, Panasonic, and LG all had plans to introduce the capabilities in a variety of television sets that will soon come to market. In addition, 3-D Blu-Ray players are also expected later this year.
High-definition televisions (or HDTV, or just HD) offer resolution substantially higher than traditional television systems. HD has one or two million pixels per frame, roughly five times that of standard-definition television (SDTV). Early high-definition broadcasting used analog techniques, but today HDTV is digitally broadcast using video compression.
HDTV technology was introduced in the United States in the 1990s. Field testing was completed in 1994. The first public high-definition broadcast in the United States occurred on July 23, 1996.
At a minimum, high-definition has twice the linear resolution of the standard. It shows greater detail than either analog television or regular DVD. The technical standards for broadcasting HDTV can also increase image resolution.
The optimum format for a broadcast depends upon the type of video graphics recording medium used and the image’s characteristics. The field and frame rate should match the resolution. A very high-resolution source may require more bandwidth than available in order to be transmitted without loss of fidelity.
