Type of LCD TV Panel Technology

Posted on 2010 by admin

Today LCD TV dominant display technology, compare to Plasma, CRT, and etc. For LCD (liquid crystal display), there are many different type of panel technologies used for production of LCD televisions and LCD monitors. LCD panel technology not limit by LED LCD TV or CCFL LCD TV, it is independent from the backlighting technology and it do contribute to contract ratio, brightness, switching speed (or respond time), viewing angle and color depth. The budget panel technology is TN panel, while the expensive panel technology target high-end market and professional quality are S-IPS and S-PVA panels. The average consumer usually has no idea what panel technology is used in their LCD TV, simply because the panel type is rarely listed by the manufacturer in the LCD TV specifications. Many buyers buy LCD TV based on price and size. Price should be a factor, but you should still know the advantages and disadvantages of the different LCD panel types and be able to identify them before you decide which LCD TV (model and brand) to purchase.

Technical Comparison of Interlace and Progressive Technology

Posted on 2010 by admin

Progressive or noninterlaced scanning (or P-Scan) is a method for displaying, storing or transmitting moving images in which all the lines of each frame are drawn in sequence. This is in contrast to the interlacing used in traditional television systems where only the odd lines, then the even lines of each frame (each image now called a field) are drawn alternatively. With progressive scan, an image is captured, transmitted and displayed in a path similar to text on a page: line by line, from top to bottom. Progressive video is what your computer screen uses. The whole image is sent to the screen from top to bottom in one pass. This provides a more “stable” and natural looking image.

LCD Technology Still Top Mobile Displays

Posted on 2009 by admin

Mobile phone displays are still dominated by LCD technology, but a few other technologies — some new and others not so new — are trying to carve out their place in the market, according to research from ABI Research.

As a mature technology, liquid crystal display (LCD) currently has a cost advantage over other display technologies, and ABI stated that it will remain the primary display technology for the foreseeable future. However, although LCD displays have improved a lot over the years, the technology performance falls short in areas like power consumption and readability in bright light conditions.

“Of the challengers, organic light-emitting diodes (OLEDs) are among leading contenders because of the maturity of their development and their use in other devices, such as televisions, which will strengthen their supply chain,” said Kevin Burden, research director of ABI Research.

Another contender is Qualcomm’s micro-electro-mechanical systems (MEMS)-based “mirasol” display, which ABI stated is finding its first role in secondary screens found on clamshell handsets. Qualcomm plans to open a dedicated mirasol display factory in Taiwan in 2009, which will be another big step in ramping up its supply chain, the research company stated.

Samsung and LG Expand LCD TV Market Lead

Samsung LED LCD TV

In recent years, Korean, Taiwanese, and Japanese makers of liquid-crystal display panels have fought hard to establish dominance in the key tech market. And for most of 2007 and 2008 there was plenty of business to go around. Today, though, the economic crisis is slashing demand for the panels, used in flat-panel TVs, computer monitors, and cell-phone screens. While that’s likely to hurt everyone in the battle, the Koreans expect the downturn to play out to their advantage. “This challenging period will give us a good opportunity to widen our lead,” says Lee Bang Soo, a vice-president at LG Display, the world’s second-largest LCD panel maker after its compatriot Samsung Electronics.The Koreans are already gaining. Manufacturing costs today exceed what producers can charge for the panels, so Taiwan’s four biggest makers have slashed output by half or more. AU Optronics (AUO), the leader in Taiwan and the global No. 3, saw its market share for panels bigger than 10 inches plunge to 11% in November, from 19.2% in January, while share for Taiwan’s Chi Mei Optoelectronics fell to 9%, from 12%, says market researcher DisplaySearch. Samsung, meanwhile, increased its share in the segment by 8.5 percentage points, to 32.5%, during the period, and LG jumped 3.1 points, to 23.5%.

Technology beneath LCD TV (Twisted Nematic, In-plane Switching, MVA/PVA)

Posted on 2009 by admin
One item that manufacturers don’t usually make a big deal about happens to be the aspect of any display that seems to matter most – LCD panel technology. There are three main categories of panel technology: TN (twisted nematic), MVA/PVA (multi-domain vertical alignment/patterned vertical alignment), and IPS (in-plane switching). Opinions about which technology is actually best differ somewhat, but there’s no denying the fact that TN is substantially cheaper to produce whereas PVA and IPS are more expensive. These days, the vast majority of LCD are once again using TN LCD panels, largely because of the pricing advantage. If you want a higher quality panel using MVA, PVA, or IPS you will need to be prepared to pay anywhere from 50% to 300% more, depending on overall quality.

LCD TV Specification Fact 1 – Dynamic Contrast Ratio & Response Time

Posted on 2009 by admin
Contrast Ratio Comparison Between LCD TV

Contrast Ratio Comparison Between LCD TV

Many LCD specifications are prone to inflation by the manufacturers or have become largely meaningless. Take contrast ratio for example. That’s the white level divided by the black level, and if you could actually get pure black on any LCD contrast ratio would be “infinity”. In practice, anything over 500:1 is sufficient, and 1000:1 is about the best you can see before the manufacturers start playing tricks. What sort of tricks? How about dynamic contrast ratio, where the backlight intensity changes according to the content currently being shown on the display.
