Caring for your LCD TV

Temperature / Humidity

It is recommended to use the product at room temperature and humidity in order to maintain it's optimum performance

1. Product lifetime can be shortened when it is used under conditions of high temperature and humidity.
	2. When it is used at low temperature of 10°C or lower, response time and brightness are affected in such a way that the proper display may not be obtained.
3. When exposed to drastic fluctuation of temperature (hot to cold or cold to hot), the product may be affected; specifically, drastic temperature fluctuation from cold to hot, produces dew on the surface which may affect the operation of the polarizer and product.
Environmental Consideration It is recommended to use the product in a clean place and to exercise caution to ensure it is not affected by dust or liquids, etc.
1. If used in dusty place, dust may cause an electrical short inside the product resulting in malfunction
	2. If the product is contaminated by humid or liquid substance, polarizer may be discolored. If the liquid enters may enter the product to cause electrical failure or corrosion which, in turn, may lead to malfunction
Handling As LCD is a product made of glass, caution must be exercised in using it. It is recommended to handle it with care since shock, vibration, and careless handling may seriously affect the product.
1. The LCD surface is made of a soft film that is vulnerable to scratch and thus to damage by a sharp article.
	2. Since the LCD is made of glass, it may be damaged if it is bent. If it falls from a high place or receives a strong shock, the glass may be broken.
3. The LCD product is composed of sensitive electronic parts and components. Therefore it must be grounded by ESD protection equipment (wrist band, etc.) before it is directly handled.
	4. It is recommended that the product be handled with soft gloves during Assembly, etc. The LCD surface is made of soft film, vulnerable to scratches and thus to damage by a sharp articles.
5. Do not bend or stretch the back light wire.
	6. It is recommended that the product surface be cleaned it is dirty by using IPA (Isoprophyl Alcohol) or Hexane. Keytone type material (Acetone), Ethyl or Methyl chloride must not be used as they can cause damage to the Polarizer.
7. The Driver IC of the LCD TV for a Notebook PC is exposed on the back of the screen. If mechanical stress is applied to this area, it can cause failure. Do not hold or press this part with your hands.
Usage As LCD is a sensitive electronic equipment, it is urged to comply with following precautions.
1. Never disassemble LCD product under any circumstances. If unqualified operators or users assemble the product after disassembling it, it may not function or its operation may be seriously affected.
	2. When it is not in use, the screen must be turned off or the pattern must be frequently changed by a screen saver. If it displays the same pattern for a long period of time, brightness down/image sticking may develop due to the LCD structure.
3. It is recommended that the product be stored in a cool and dry place in its original product box.
	4. Please dispose of the product according to the relevant laws and regulations. A small quantity of mercury is contained in lamp inside LCD product.

New Philips TVs are what women want

By Ella Morton on 08 January 2008

What is Philips' development process when following an Editors' Choice winning product like the Aurea TV? Simple: just ask the ladies what they're into.

Introducing the new Design Collection of plasma and LCD screens, CEO Andrea Ragnetti explained their strategy: women, according to Philips' research, are "more critical consumers who need to see the personal benefits of a product".

Not just that, "they want it to make them feel good," Ragnetti said.

These conclusions have led to a range of televisions that is essentially "once more, with feeling": similar to what we've seen before, but with softer edges.

The new 7000 Series of feelgood flat screens is all about smooth, almost Apple-esque contours and rounded bezels. Whether or not you're into the touchy-feely shtick -- Ragnetti says the company is "taking once-familiar objects and giving them a new sense of intimacy so we can engage with them more fully, more emotionally" -- you can't deny they're pretty sexy.

Ranging from 19 to 52 inches (48 to 132cm), the TVs feature an invisible speaker -- there are no grilles or perforations to clutter up those smooth surfaces. Available with or without Ambilight lighting effects, the models also sport four HDMI 1.3 ports and a reduced response time of 2ms (compared with the 5ms of the previous series). An acrylic edged bezel seals the swanky deal.

Dolby does digital TV

Dolby, the sound company, is getting into TVs.

This week the company was at Ceatec, Japan's largest electronics trade show, to promote Dolby Contrast and Dolby Vision, two technologies (one currently real, one on the drawing board) to extend its reach into digital TV and cinema.

Both Dolby Contrast and Dolby Vision are essentially ways to apply the dimmer switch concept to light emitting diodes. LEDs are being increasingly used as the backlight in flat panel LCD TVs and Dolby Contrast allows the TV to dynamically adjust. One LED could go completely black while its neighbour could be full or high, or the two could offer light that creates slightly different shades of tan. "You get much better blacks," said Gaven Wang, senior video product manager at Dolby.

Dolby Contrast can be used on current LEDs, while Dolby Vision is more of a long-term technology that will apply to LEDs that emit more lumens, or light, per watt.

Black has always been a problem for LCDs, so the Dolby technology could heighten the competition with plasma. Plasma TVs do well with black, unlike conventional LCDs.

The technology could even create a third category of displays, according to analyst Richard Doherty of Envisioneering. Interestingly, NXP Semiconductor, formerly Philips Semiconductor, has come up with a technology that functions differently but with similar results.

The problem now lies in finding customers. Dolby as yet has no signed contracts to announce, but hopes TVs employing the technology will come out next year or in 2009. The fact that Dolby is at Ceatec, where many of the world's largest TV makers are showing off their latest goods, shows that the company is seeking out the right people.

Dolby didn't invent this technology itself, but acquired it from a company it purchased called Brightside. Dolby is no stranger to video, however -- founder Ray Dolby started out by developing a system for removing noise and artifacts out of black-and-white video footage.

Dolby also demonstrated its 3D cinema technology at the show. Theatre owners pay about US$26,000 for the system, which revolves around doing a software upgrade to digital servers. That price tag is relatively cheap, according to Dolby. The company's 3D technology will get a full international airing when Beowulf premieres later this year as many 3D theatres use Dolby's tech.
