The liquid crystal display (LCD) technology has been used in several electronic products over the years. There are more reasons for LCDs to be more endearing than CRTs.

Dr Pan: Hello, Greg. VA is the abbreviation for Vertical Alignment. VA LCD is a negative and transmissive display with LED backlight. The background color is pure black. VA LCD technology is the only way for monochrome LCD screen to make the pure black background. The color of the letters is the color of LED backlight (usually white). If we want to display multi-color, some special color films will be added to the bottom of ITO glass.

The maximum COM is 16, so it is not suitable for the large dot matrix and complicated displays. It is a perfect display for the pure black background high end devices.

H30 is a robust field housing in aluminum or stainless steel designed for tough environments. The field housing is available both with and without digital LCD indicator for installation directly in a 4-20 mA loop without need for external power. The LCD indicator is equipped with high-contrast, easy-to-read LCD digits with backlight. The scale is easily programmable, without reference signal, by two push buttons for any values between – 1999 and 9999.

Macnica offers a variety of services to enhance our LCD displays, including OPTICAL BONDING, TOUCH SCREEN and COVER GLASS OPTIONS, and CUSTOMIZED WAREHOUSING AND LOGISTICS.

The -ms-high-contrast CSS media feature is a Microsoft extension that describes whether the application is being displayed in high contrast mode, and with what color variation.

High Contrast Mode is a specialized display mode that prioritizes making content as legible as possible by dynamically replacing foreground and background colors with a user-specified theme. For web content, theme colors are mapped to content types.

Contrast ratio should be black and white. Taken at face value, it"s the ratio of the light level (luminance) the display produces when fed a white signal to the luminance when it"s fed a black signal. Unfortunately, it"s probably the most misused, inflated, and ultimately misleading specification used to describe HDTVs today.

At the 2009 Consumer Electronics Show, manufacturers quoted contrast ratio specs of 1,000,000:1 or 2,000,000:1 for upcoming Samsung and Sony for their current LED models. Those numbers sure do sound impressive, but what do they mean in the real world?

Very little. It"s true that in general, a higher contrast ratio can indicate that the display produces a deeper level of black, with all of the picture-quality benefits that brings--but then again it might not. Despite the million-to-one contrast ratios of the Samsung and Sony LED sets we reviewed, we observed better black-level performance in the Pioneer PRO-111FD. Pioneer doesn"t publish a contrast ratio spec for that television, but has claimed that its black levels are so deep as to be "immeasurable."

Manufacturers are free to use whatever method they like to "measure" the contrast ratio of their displays. The big numbers you see quoted most often are for "dynamic" contrast ratio, which takes into account changes the (usually LCD) display makes to adjust for fluctuations in the brightness of the content--namely, lowering the backlight in dark scenes and bringing it up in lighter ones. Then there"s the "native" contrast ratio number, always much smaller than the dynamic one, where the display doesn"t perform these adjustments. Both of these numbers are usually derived from the measurement of a full-white screen and a full-black screen (so-called full-on, full-off measurements), which is obviously not representative of actual program material.

A more-representative method is the ANSI contrast ratio measurement, which uses a checkerboard of eight white and eight black squares; the average luminance of the white and black squares determines the contrast ratio. Unfortunately, you"ll almost never see any manufacturer quote an ANSI number, since it"s usually tiny in comparison--a few hundred or few thousand or so to one.

We have seen some signs of millions-fatigue in the CR spec game, however. At CES 2009, Samsung"s press material didn"t publish a number, instead using the phrase "mega-contrast" without any accompanying number. LG and Vizio use the same phrase, but did publish the numbers. We"ve already mentioned how Pioneer is avoiding numbers, and we hope more TV makers follow suit. When the numbers can be so inflated or simply made up, what"s the point?

That"s why we hope you"ll pay as little attention to published contrast ratio specs as we do. We rarely mention them in reviews, and when we have to refer to them in news or blog posts we try to put them in context, comparing last year"s specs from the same manufacturer with this year"s, for example. We"re still working on performing contrast ratio measurements ourselves as part of TV reviews, so look for that to happen this year. When it does, we doubt we"ll publish anything close to "one million."

Liquid Crystal Display (LCD) screens are a staple in the digital display marketplace and are used in display applications across every industry. With every display application presenting a unique set of requirements, the selection of specialized LCDs has grown to meet these demands.

LCD screens can be grouped into three categories: TN (twisted nematic), IPS (in-plane switching), and VA (Vertical Alignment). Each of these screen types has its own unique qualities, almost all of them having to do with how images appear across the various screen types.

This technology consists of nematic liquid crystal sandwiched between two plates of glass. When power is applied to the electrodes, the liquid crystals twist 90°. TN (Twisted Nematic) LCDs are the most common LCD screen type. They offer full-color images, and moderate viewing angles.

TN LCDs maintain a dedicated user base despite other screen types growing in popularity due to some unique key features that TN display offer. For one,

Displays with VA screens deliver wide viewing angles, high contrast, and good color reproduction. They maintain high response rates similar to TN TFTs but may not reach the same sunlight readable brightness levels as comparable TN or IPS LCDs. VA displays are generally best for applications that need to be viewed from multiple angles, like digital signage in a commercial setting.

IPS is superior in contrast, brightness, viewing angles, and color representation compared to TN screens. Images on screen retain their quality without becoming washed out or distorted, no matter what angle they’re viewed from. Because of this, viewers have the flexibility to view content on the screen from almost anywhere rather than having to look at the display from a front-center position.

Based on current trends, IPS and TN screen types will be expected to remain the dominant formats for some time. As human interface display technology advances and new product designs are developed, customers will likely choose IPS LCDs to replace the similarly priced TN LCDs for their new projects.
