High definition TVs (HDTVs) are slimming down while their pictures and capabilities are beefing up.
Innovations at the world's largest consumer electronics show in Las Vegas underscore the trend, with Sony wowing visitors with a 3mm-thick Organic Light Emitting Diode (OLED) TV.
While liquid crystal display (LCD) TVs use backlights, OLED's picture-creating pixels come from screens that can be made paper thin and bendable while using less power.

Sony of America chief executive Howard Stringer proclaimed OLED a new industry standard, saying "even the name sounds like a Viking warlord."
"This is the future of television," Jose Albanez of Sony said on Wednesday while guarding a roped-off OLED display on the exhibit floor of the Consumer Electronics Show (CES).
OLED TVs hit store shelves in Japan last month and were launched in the US market this week at a price of US$2,500 dollars.
Albanez told price-conscious visitors that the cost of the TVs would drop "eventually."
Samsung revealed at the conference a pair of OLED TV prototypes it envisions having to market in a couple of years.
Pioneer showed off a "concept model" 50-inch LCD HDTV just 9mm deep, saying it intended to have it ready for consumers within three years.
Hitachi's 1.5-inch-thick LCD model is already on the market.
Philips and Texas Instruments presented flat televisions with 3-D images.
Texas Instruments eye glasses link wirelessly to TVs and alter slightly the images reaching each eye.
The principle behind seeing 3-D images is that each of a person's eyes sees a different perspective and the brain combines the images to create a sense of depth.
"The glasses sync to the TV and then your brain kicks in and sees 3-D," Ken Bell of Texas Instruments said while demonstrating the TV sets.
Texas Instruments uses the same technology in a "dual view" TV that lets video game players compete head-to-head in racing or shooter games, but only see their character on the screen.
"Each player gets the full screen and no more screen cheating," Bell said, referring to being able to take premature peeks at what opponents are doing.
"It's pretty neat," he said.
Philips's 3-D TVs don't require special glasses. The sets split image signals so different pictures hit different eyes.
"It can see a little blurry at first, but your eyes need to adjust to it," Bjorn Teuwsen of Philips said as he and others gazed at a model on the CES show floor.
"It appeals to your senses. You get more excited. We see it in studies -- people start sweating because it is so immersive," he said.
Philips began selling the 3-D TVs in Europe last month and will offer them in the US sometime this year.
Early interest in buying the Philips 3-D sets has come from casinos, taverns, shopping centers and other businesses due to their hefty price tags, Teuwsen said.
The smallest model, 20-inches diagonally, is priced US$3,670.
Among the dizzying selection of slim flat screen TVs are many that boast online connections, bypassing computers when it comes to watching Internet streamed TV shows, films or video clips.
A Toshiba TV incorporates online social networking by letting people watching a TV show link online with others viewers.
Friends can exchange instant messages on their screens during the shows.
MORE VISITORS: The Tourism Administration said that it is seeing positive prospects in its efforts to expand the tourism market in North America and Europe Taiwan has been ranked as the cheapest place in the world to travel to this year, based on a list recommended by NerdWallet. The San Francisco-based personal finance company said that Taiwan topped the list of 16 nations it chose for budget travelers because US tourists do not need visas and travelers can easily have a good meal for less than US$10. A bus ride in Taipei costs just under US$0.50, while subway rides start at US$0.60, the firm said, adding that public transportation in Taiwan is easy to navigate. The firm also called Taiwan a “food lover’s paradise,” citing inexpensive breakfast stalls
TRADE: A mandatory declaration of origin for manufactured goods bound for the US is to take effect on May 7 to block China from exploiting Taiwan’s trade channels All products manufactured in Taiwan and exported to the US must include a signed declaration of origin starting on May 7, the Bureau of Foreign Trade announced yesterday. US President Donald Trump on April 2 imposed a 32 percent tariff on imports from Taiwan, but one week later announced a 90-day pause on its implementation. However, a universal 10 percent tariff was immediately applied to most imports from around the world. On April 12, the Trump administration further exempted computers, smartphones and semiconductors from the new tariffs. In response, President William Lai’s (賴清德) administration has introduced a series of countermeasures to support affected
CROSS-STRAIT: The vast majority of Taiwanese support maintaining the ‘status quo,’ while concern is rising about Beijing’s influence operations More than eight out of 10 Taiwanese reject Beijing’s “one country, two systems” framework for cross-strait relations, according to a survey released by the Mainland Affairs Council (MAC) on Thursday. The MAC’s latest quarterly survey found that 84.4 percent of respondents opposed Beijing’s “one country, two systems” formula for handling cross-strait relations — a figure consistent with past polling. Over the past three years, opposition to the framework has remained high, ranging from a low of 83.6 percent in April 2023 to a peak of 89.6 percent in April last year. In the most recent poll, 82.5 percent also rejected China’s
PLUGGING HOLES: The amendments would bring the legislation in line with systems found in other countries such as Japan and the US, Legislator Chen Kuan-ting said Democratic Progressive Party (DPP) Legislator Chen Kuan-ting (陳冠廷) has proposed amending national security legislation amid a spate of espionage cases. Potential gaps in security vetting procedures for personnel with access to sensitive information prompted him to propose the amendments, which would introduce changes to Article 14 of the Classified National Security Information Protection Act (國家機密保護法), Chen said yesterday. The proposal, which aims to enhance interagency vetting procedures and reduce the risk of classified information leaks, would establish a comprehensive security clearance system in Taiwan, he said. The amendment would require character and loyalty checks for civil servants and intelligence personnel prior to
