A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display that uses thin-film-transistor technologyactive matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments.

In February 1957, John Wallmark of RCA filed a patent for a thin film MOSFET. Paul K. Weimer, also of RCA implemented Wallmark"s ideas and developed the thin-film transistor (TFT) in 1962, a type of MOSFET distinct from the standard bulk MOSFET. It was made with thin films of cadmium selenide and cadmium sulfide. The idea of a TFT-based liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in 1968. In 1971, Lechner, F. J. Marlowe, E. O. Nester and J. Tults demonstrated a 2-by-18 matrix display driven by a hybrid circuit using the dynamic scattering mode of LCDs.T. Peter Brody, J. A. Asars and G. D. Dixon at Westinghouse Research Laboratories developed a CdSe (cadmium selenide) TFT, which they used to demonstrate the first CdSe thin-film-transistor liquid-crystal display (TFT LCD).active-matrix liquid-crystal display (AM LCD) using CdSe TFTs in 1974, and then Brody coined the term "active matrix" in 1975.high-resolution and high-quality electronic visual display devices use TFT-based active matrix displays.

The liquid crystal displays used in calculators and other devices with similarly simple displays have direct-driven image elements, and therefore a voltage can be easily applied across just one segment of these types of displays without interfering with the other segments. This would be impractical for a large display, because it would have a large number of (color) picture elements (pixels), and thus it would require millions of connections, both top and bottom for each one of the three colors (red, green and blue) of every pixel. To avoid this issue, the pixels are addressed in rows and columns, reducing the connection count from millions down to thousands. The column and row wires attach to transistor switches, one for each pixel. The one-way current passing characteristic of the transistor prevents the charge that is being applied to each pixel from being drained between refreshes to a display"s image. Each pixel is a small capacitor with a layer of insulating liquid crystal sandwiched between transparent conductive ITO layers.

The circuit layout process of a TFT-LCD is very similar to that of semiconductor products. However, rather than fabricating the transistors from silicon, that is formed into a crystalline silicon wafer, they are made from a thin film of amorphous silicon that is deposited on a glass panel. The silicon layer for TFT-LCDs is typically deposited using the PECVD process.

Polycrystalline silicon is sometimes used in displays requiring higher TFT performance. Examples include small high-resolution displays such as those found in projectors or viewfinders. Amorphous silicon-based TFTs are by far the most common, due to their lower production cost, whereas polycrystalline silicon TFTs are more costly and much more difficult to produce.

The twisted nematic display is one of the oldest and frequently cheapest kind of LCD display technologies available. TN displays benefit from fast pixel response times and less smearing than other LCD display technology, but suffer from poor color reproduction and limited viewing angles, especially in the vertical direction. Colors will shift, potentially to the point of completely inverting, when viewed at an angle that is not perpendicular to the display. Modern, high end consumer products have developed methods to overcome the technology"s shortcomings, such as RTC (Response Time Compensation / Overdrive) technologies. Modern TN displays can look significantly better than older TN displays from decades earlier, but overall TN has inferior viewing angles and poor color in comparison to other technology.

Most TN panels can represent colors using only six bits per RGB channel, or 18 bit in total, and are unable to display the 16.7 million color shades (24-bit truecolor) that are available using 24-bit color. Instead, these panels display interpolated 24-bit color using a dithering method that combines adjacent pixels to simulate the desired shade. They can also use a form of temporal dithering called Frame Rate Control (FRC), which cycles between different shades with each new frame to simulate an intermediate shade. Such 18 bit panels with dithering are sometimes advertised as having "16.2 million colors". These color simulation methods are noticeable to many people and highly bothersome to some.gamut (often referred to as a percentage of the NTSC 1953 color gamut) are also due to backlighting technology. It is not uncommon for older displays to range from 10% to 26% of the NTSC color gamut, whereas other kind of displays, utilizing more complicated CCFL or LED phosphor formulations or RGB LED backlights, may extend past 100% of the NTSC color gamut, a difference quite perceivable by the human eye.

The transmittance of a pixel of an LCD panel typically does not change linearly with the applied voltage,sRGB standard for computer monitors requires a specific nonlinear dependence of the amount of emitted light as a function of the RGB value.

It achieved pixel response which was fast for its time, wide viewing angles, and high contrast at the cost of brightness and color reproduction.Response Time Compensation) technologies.

Less expensive PVA panels often use dithering and FRC, whereas super-PVA (S-PVA) panels all use at least 8 bits per color component and do not use color simulation methods.BRAVIA LCD TVs offer 10-bit and xvYCC color support, for example, the Bravia X4500 series. S-PVA also offers fast response times using modern RTC technologies.

When the field is on, the liquid crystal molecules start to tilt towards the center of the sub-pixels because of the electric field; as a result, a continuous pinwheel alignment (CPA) is formed; the azimuthal angle rotates 360 degrees continuously resulting in an excellent viewing angle. The ASV mode is also called CPA mode.

TFT dual-transistor pixel or cell technology is a reflective-display technology for use in very-low-power-consumption applications such as electronic shelf labels (ESL), digital watches, or metering. DTP involves adding a secondary transistor gate in the single TFT cell to maintain the display of a pixel during a period of 1s without loss of image or without degrading the TFT transistors over time. By slowing the refresh rate of the standard frequency from 60 Hz to 1 Hz, DTP claims to increase the power efficiency by multiple orders of magnitude.

Due to the very high cost of building TFT factories, there are few major OEM panel vendors for large display panels. The glass panel suppliers are as follows:

External consumer display devices like a TFT LCD feature one or more analog VGA, DVI, HDMI, or DisplayPort interface, with many featuring a selection of these interfaces. Inside external display devices there is a controller board that will convert the video signal using color mapping and image scaling usually employing the discrete cosine transform (DCT) in order to convert any video source like CVBS, VGA, DVI, HDMI, etc. into digital RGB at the native resolution of the display panel. In a laptop the graphics chip will directly produce a signal suitable for connection to the built-in TFT display. A control mechanism for the backlight is usually included on the same controller board.

The low level interface of STN, DSTN, or TFT display panels use either single ended TTL 5 V signal for older displays or TTL 3.3 V for slightly newer displays that transmits the pixel clock, horizontal sync, vertical sync, digital red, digital green, digital blue in parallel. Some models (for example the AT070TN92) also feature input/display enable, horizontal scan direction and vertical scan direction signals.

New and large (>15") TFT displays often use LVDS signaling that transmits the same contents as the parallel interface (Hsync, Vsync, RGB) but will put control and RGB bits into a number of serial transmission lines synchronized to a clock whose rate is equal to the pixel rate. LVDS transmits seven bits per clock per data line, with six bits being data and one bit used to signal if the other six bits need to be inverted in order to maintain DC balance. Low-cost TFT displays often have three data lines and therefore only directly support 18 bits per pixel. Upscale displays have four or five data lines to support 24 bits per pixel (truecolor) or 30 bits per pixel respectively. Panel manufacturers are slowly replacing LVDS with Internal DisplayPort and Embedded DisplayPort, which allow sixfold reduction of the number of differential pairs.

The bare display panel will only accept a digital video signal at the resolution determined by the panel pixel matrix designed at manufacture. Some screen panels will ignore the LSB bits of the color information to present a consistent interface (8 bit -> 6 bit/color x3).

With analogue signals like VGA, the display controller also needs to perform a high speed analog to digital conversion. With digital input signals like DVI or HDMI some simple reordering of the bits is needed before feeding it to the rescaler if the input resolution doesn"t match the display panel resolution.

The statements are applicable to Merck KGaA as well as its competitors JNC Corporation (formerly Chisso Corporation) and DIC (formerly Dainippon Ink & Chemicals). All three manufacturers have agreed not to introduce any acutely toxic or mutagenic liquid crystals to the market. They cover more than 90 percent of the global liquid crystal market. The remaining market share of liquid crystals, produced primarily in China, consists of older, patent-free substances from the three leading world producers and have already been tested for toxicity by them. As a result, they can also be considered non-toxic.

A TFT LCD monitor is a type of flat-panel display that works as either a computer monitor or as a display for a TV. TFT LCD is short for thin film transistor liquid crystal display. Most of the time, manufacturers shorten the term for such displays to LCD, dropping the TFT from the name since this abbreviation simply refers to the type of LCD monitor, and TFT is easily the most popular type.

The thin film transistor consists of a thin piece of a semiconductor material applied over a glass substrate. Each pixel has its own transistor along with the liquid crystal material. The liquid crystal material exhibits properties of both a liquid, because of its ability to change quickly, and a crystal, because of its ability to remain in an arranged position. The transistor applies a voltage to the pixel, determining its color and intensity. A pixel is short for picture element, and the tiny pixels blend together to create the image on a display.

Another name for a TFT LCD monitor is an active-matrix LCD. Although TFT is not the only active-matrix technology, it is overwhelmingly the most common type, causing some people use the two terms interchangeably. A TFT is only a small part of an active-matrix LCD, however. The term active-matrix refers to the ability of the monitor to control individual pixels and switch them quickly.

Active-matrix LCDs differ from passive-matrix LCDs in several ways. They have a high refresh rate, high contrast, and high response times, at least when compared to passive-matrix displays. A passive-matrix LCD is commonly found in a calculator display or a digital wristwatch, where the display contains a limited number of segments and does not require full color. Active-matrix displays usually are high-resolution, full-color LCDs, and they include those found in computer displays, cell phones, and TVs.

A few different types of thin film transistor technology may be are found in a TFT LCD monitor. The most common for computer displays and TVs is called a twisted nematic (TN) display, which features quick response times. TN displays do not excel in the areas of screen viewing angle and color reproduction, however. Another common monitor technology is IPS, short for in-plane switching. An IPS display offers great color and good viewing angles, but its refresh rates are slow.

IPS (In-Plane Switching) lcd is still a type of TFT LCD, IPS TFT is also called SFT LCD (supper fine tft ),different to regular tft in TN (Twisted Nematic) mode, theIPS LCD liquid crystal elements inside the tft lcd cell, they are arrayed in plane inside the lcd cell when power off, so the light can not transmit it via theIPS lcdwhen power off, When power on, the liquid crystal elements inside the IPS tft would switch in a small angle, then the light would go through the IPS lcd display, then the display on since light go through the IPS display, the switching angle is related to the input power, the switch angle is related to the input power value of IPS LCD, the more switch angle, the more light would transmit the IPS LCD, we call it negative display mode.

The regular tft lcd, it is a-si TN (Twisted Nematic) tft lcd, its liquid crystal elements are arrayed in vertical type, the light could transmit the regularTFT LCDwhen power off. When power on, the liquid crystal twist in some angle, then it block the light transmit the tft lcd, then make the display elements display on by this way, the liquid crystal twist angle is also related to the input power, the more twist angle, the more light would be blocked by the tft lcd, it is tft lcd working mode.

A TFT lcd display is vivid and colorful than a common monochrome lcd display. TFT refreshes more quickly response than a monochrome LCD display and shows motion more smoothly. TFT displays use more electricity in driving than monochrome LCD screens, so they not only cost more in the first place, but they are also more expensive to drive tft lcd screen.The two most common types of TFT LCDs are IPS and TN displays.

Julia Nielsen is a jack-of-all-trades writer, having written for newspapers, magazines, websites, and blogs for the last 15 years. When she"s not dabbling in the written world, she"s spending time with her beautiful granddaughter. She loves to hear from readers, especially when they offer chocolate.

The two buzzwords the tech world has been chatting about for a number of years now is IPS, (In-Plane Switching) screen technology used for liquid crystal displays or LCD’s for short, and TFT (Thin-Film-Transistor) an active matrix screen technology, which is more expensive, but a sharper image.

Designed in the 1980’s, but not introduced until nearly a decade later, in 1996, by Hitachi, IPS technology is nothing new, and a type of LCD design that affords greater viewing angles and higher-quality color reproduction than the traditional TN or Twisted Nematic LCDs.

When Apple brought it to the public’s attention, it took off, and as they say, the rest is history; but, it really didn’t become widespread or worldwide until just the late 1990’s. Since then, IPS screens have been implemented in homes all over the world, with variations to suit one’s electronic needs.

TFT (Thin-Film-Transistor) Liquid Crystal Display is a thin display type, where a transistor embedded into each crystal gate; these transistors are then printed on thin-transparent film. The technology was designed to improve image qualities, such as contrast and addressability.

Also designed in the late 1980’s, TFT display technologies is just another variation of LCD displays that offer greater color, contrast, and response times as opposed to available passive matrix LCD’s. One of the primary differences between IPS and TFT display technologies is the cost. IPS is more expensive than TN technology. However, there are some key differences between the two that should be noted.

Before we go into the differences, let’s talk about features of each technology. Note that we’re not talking TVs, computer, or tablets, but screens on a much smaller scale, (think 7” or smaller) which uses different rules to fit that scale. First, it’s interesting to discover that the TFT display technologies is the most common type of color display technology; more monochrome displays still out-sell color, due to lower cost and lower power consumption, however, the narrow poor visibility of TFTs in direct sunlight is their downside; but I’m getting ahead of myself here.

IPS technology has come a long way in regards to cell phones and other LCD screens that are even much smaller. (Picture digital clocks on a radio, microwave, and hand-held games) Some of the features of an IPS screen include:Wider viewing angles – crystals are aligned horizontally rather than vertically, so it allows for better angled viewing, perfect for smaller screens, where you need to rotate the screen for better viewing

Lower power consumption, resulting in longer battery life – again for smaller screens, this works great, because even though this technology requires more power, a smaller screen has less power drain.

Variations to help with user’s viewing requirements or desires – there are several different forms of IPS technology: Super-IPS, (S-IPS) Advanced Super IPS, Advanced S-IPS, where the liquid crystal molecules stay parallel to the front and back panels, instead of perpendicular when a voltage is applied

TFT display technologies have developed over the years and have become quite popular in tech circles. The features offered with this advancing technology are:Superior color display – for technology that requires it or for consumers that desire color screens

Features a longer half-life, (half-life is the amount of time in hours before the display is 50% as bright as when it was first turned on), than OLEDs and comes in varying sizes, from under an inch up to over 15 inches

Capacitive Touchscreen or touch panel, which is in the majority of Smartphones and allows for additional functionality, specifically for zooming and scrolling

Aspect ratio control, which refers to a screen’s ability to maintain an aspect ratio of a source image at the hardware level, and 1:1 pixel mapping, used to literally “map” the exact number of pixels specifically in the source resolution to pixels on the screen

Variety of displays, which can be interfaced through a variety of bus types, including 18 and 24 bit for red/green/blue, LVDS, and 8 bit and 16 bit for a CPU – many controllers allow for two or more different types of interfaces on the same TFT screen

Okay, now that we’ve covered the features of both technologies, let’s look at the differences between the two. Before we get into the spec differences, let’s first address the main difference: the arrangement of transistors and liquid crystal. Seems vague, doesn’t it?

Let me explain. As you can see, both have excellent color display and clarity; however, IPS screens offer greater color reproduction and viewing angles because of the way crystal orientation and polarizers are arranged. In a TFT screen, the structure of the crystals results in angular retardation in the light. The IPS screens thus offer less distortion properties. Other differences include power consumption and cost. With IPS screens, it takes more power (up to 15% more) than with a TFT screen. If you’re on a monitor, such as a computer screen that’s bigger than 7 inches, it will drain your battery faster than if you’re on a 3.5” screen. Regarding cost, IPS panels are more expensive to produce than TFT panels.

Here’s why:IPS screens are popular and in high demand with professionals including surgeons and photographers or pretty much any profession that requires color reproduction, therefore, because the demand is high, the price goes up. (way to love economics) Also, less manufactures are building IPS at this time.

If you want the benefits of having a Smartphone without a huge price tag, then TFT devices are your best bet. Another difference is that IPS screens have longer response times than TFT screens, so the lag output is greater. A few other key differences to be aware of are that with IPS panels, you get a bigger variety of panels, as was discussed above, with their super, advanced, and so forth developments, giving the consumer options, and IPS screens that can display 24-bit TrueColor; they also stay color-accurate and remain stable.

So, are you ready to delve into the pros and cons of these two technologies? Granted, we’ve touched on their features and differences, but now it’s time to ask yourself, which one is better for me or my business?

We’ve been talking largely about Smartphone screens, but since both technologies work on smaller screens, such as clocks and timers or digital thermometers, let’s focus on those.

Because of their superior color and clarity of images, devices using an IPS screens are easy to install on walls, due to their compact form and low-depth. The Super IPS screens offer a higher angle of 170˚ for better clarity and wider viewing, particularly at night. Images remain stable and clear and not sparkly, shiny, like other screens; they also have a longer battery life and screen life, (on smaller screens of course) because of the lower electrical output. The release of heat is lower, again because of the reduced electrical consumption. The colors are also more vibrant and clear, not pixelated like other lower quality-type devices. As mentioned earlier, there are also many variations of IPS technology to suit your needs and desires.

Now we will go over the downside of IPS screens, which we briefly touched on above, which includes a major disadvantage: cost. If you’re just looking for an average Smartphone or don’t need all the fancy coloring and clarity for LCD displays, then cost may not be a big factor; however, this is the main reason why IPS technology is beginning to come down. As with every new invention, discovery or technology, demand is everything. Another disadvantage is that colors may not always transcribe correctly or accurately, which may or may not be a deterrent. Also, high resolutions are not always readily available for personal applications. In certain circumstances, the brightness may not be enough, especially in darkness.

Steve Jobs said it best: “Design is not just what it looks like and feels like. Design is how it works.” I tend to agree with him. With TFT display technologies, less energy consumption is a big deal, especially when dealing with bigger screens, and of course less electricity means lower cost, overall. The visibility is sharper, meaning no geometric distortion, which is great for these tired, old eyes. The response time and physical design of the screens are also appealing. TFT displays can also save space and be placed virtually anywhere in an office or home, because of the brightly lit feature and crisp clear images.

Some cons of TFT screens deal with the viewing angle, which create distortion, resulting in a less-than-perfect image. Static resolution, meaning the resolution can’t be changed, may also cause a problem, but newer models seem to have tackled that issue. The accuracy of the display of colors is not perfect, specifically strong blacks and bright whites, so when printing an image, it may not display the spectrum of colors.

And there you have it. In the future, even this superb technology will change and new, more exciting technology will take its place. But until then, IPS & TFT screens are forging ahead with their own advances and improvements, so stayed tune. You don’t want to miss it.

The rise of smart TVs is expected to bring lucrative business opportunities to Taiwan"s TFTLCD panel, intelligent remote controller, and WiFi industries, according to TRi.

Thin-Film Transistor-Liquid Crystal Display (TFTLCD) panels are used in computer monitors and notebooks, televisions, mobile phones and other electronic devices.

In order to record users" actions while solving the tasks without disturbing the children, we simulated the cellular phones as a software solution that was run on a PC, which was connected to a 15-inch (38-cm) touch screen (TFTLCD liyama TXA 3841, twisted nematic, with a display resolution of 1024 x 768 pixels; the touch logic was developed by ELO RS232C).

28, 2009 (CENS) -- Some thin film transistor-liquid crystal display (TFTLCD) panel manufacturers will quote higher prices for TV and monitor panels to second-and third-class system makers in late December, which is expected to raise overall panel prices in January 2010, according to industry sources.

The research firm pointed out that global thin film transistor-liquid crystal display (TFTLCD) panel manufacturers would feature 3D and touch features-even combining them in a variety of new notebook and LCD-monitor panels in 2010.

(AUO), the largest thin film transistor-liquid crystal display (TFTLCD) panel manufacturer in Taiwan, recently announced that it was honored with the 2009/2010 Ocean Tomo 300 Patent Index.

TFT-based displays have a transistor for each pixel on the screen. This allows the electrical current that illuminates the display to be turned on and off at a faster rate, which makes the display brighter and shows motion smoother. LCDs that use TFT technology are called "active-matrix" displays, which are higher-quality than older "passive-matrix" displays. TFT technology provides the best resolution of all the flat display technologies, but it is also expensive than monochrome lcd. So TFTs are used in high-quality LCD displays, if you see a LCD monitor at your local computer market, it should be an active tft lcd display, Basically, it is a high-quality tft lcd monitor.

Passive-matrix display. A passive-matrix display is anLCD screen display that contains a series of wires that cross each other. See the dual scan display for a full definition on this term.

What is an Active-matrix Display (TFT)? Alternatively referred to as TFT ( thin-film transistor) and AMLCD ( active-matrix LCD ), an active-matrix display is an LCD ( liquid crystal display) introduced with the IBM ThinkPad in 1992.

It uses a matrix of thin film transistors(TFTs) and capacitors to control the image produced by thedisplay. The brightness of each pixel is controlled by modifying the electrical charge of the corresponding capacitors.

When a voltage is applied between the upper and lower surfaces, the liquid crystal molecules are aligned in the direction of the electric field, forming a vertical alignment. At this point, the incident light is not affected by the Liquid Crystal Molecules, straight out of the lower surface.

The liquid crystal cannot emit light by itself, and the backlight should be added behind the LCD panel. A few years ago, CCFL cold cathode backlighting was the dominant market application, but with the development of technology, the LED backlight has gradually replaced the traditional CCFL backlight.

TFT stands for thin-film transistor, which means that each pixel in the device has a thin-film transistor attached to it. Transistors are activated by electrical currents that make contact with the pixels to produce impeccable image quality on the screen. Here are some important features of TFT displays.Excellent Colour Display.Top notch colour contrast, clarity, and brightness settings that can be adjusted to accommodate specific application requirements.Extended Half-Life.TFT displays boast a much higher half-life than their LED counterparts and they also come in a variety of size configurations that can impact the device’s half-life depending on usage and other factors.TFT displays can have either resistive or capacitive touch panels.Resistive is usually the standard because it comes at a lower price point, but you can also opt for capacitive which is compatible with most modern smartphones and other devices.TFT displays offer exceptional aspect ratio control.Aspect ratio control contributes to better image clarity and quality by mapping out the number of pixels that are in the source image compared to the resolution pixels on the screen.Monitor ghosting doesn’t occur on TFT displays.This is when a moving image or object has blurry pixels following it across the screen, resembling a ghost.

TFT displays are incredibly versatile.The offer a number of different interface options that are compatible with various devices and accommodate the technical capabilities of all users.

There are two main types of TFT LCD displays:· Twisted nematic TFT LCDs are an older model. They have limited colour options and use 6 bits per each blue, red, and green channel.

In-plane switching TFT LCDs are a newer model. Originally introduced in the 1990s by Hitachi, in-plane switching TFT LCDs consist of moving liquid pixels that move in contrast or opposite the plane of the display, rather than alongside it.

The type of TFT LCD monitor or industrial display you choose to purchase will depend on the specifications of your application or project. Here are a few important factors to consider when selecting an appropriate TFT LCD display technology:Life expectancy/battery life.Depending on the length of ongoing use and the duration of your project, you’re going to want to choose a device that can last a long time while maintaining quality usage.

Touch type and accuracy.What type of activities are you planning on using your device for? If it’s for extended outdoor use, then you should go with projected capacitive touch as this is more precise and accurate. Touch accuracy is important for industrial and commercial applications.

Image clarity.Some TFT displays feature infrared touchscreens, while others are layered. The former is preferable, especially in poor lighting conditions or for outdoor and industrial applications, because there’s no overlay and therefore no obstructions to light emittance.

The environmental conditions make a difference in operation and image clarity. When choosing a TFT for outdoor or industrial applications, be sure to choose one that can withstand various environmental elements like dust, wind, moisture, dirt, and even sunlight.

Pixel, also called Picture Element, A pixel is the smallest unit of a digital image or graphic that can be displayed and represented on a digital display device. A pixel is the basic logical unit in digital graphics. Pixels are combined to form a complete image, video, text, or any visible thing on a computer display

LCD display doesn’t operate the same way as CRT displays , which fires electrons at a glass screen, a LCD display has individual pixels arranged in a rectangular grid. Each pixel has RGB(Red, Green, Blue) sub-pixel that can be turned on or off. When all of a pixel’s sub-pixels are turned off, it appears black. When all the sub-pixels are turned on 100%, it appears white. By adjusting the individual levels of red, green, and blue light, millions of color combinations are possible

The pixels of the LCD screen were made by circuitry and electrodes of the backplane. Each sub-pixel contains a TFT (Thin Film Transistor) element.  These structures are formed by depositing various materials (metals and silicon) on to the glass substrate that will become one part of the complete display “stack,” and then making them through photolithography. For more information about TFT LCDs, please refer to “

The etched pixels by photolith process are the Native Resolution. Actually, all the flat panel displays, LCD, OLED, Plasma etc.) have native resolution which are different from CRT monitors

HD TV has 1280×720 = 921,600 pixels; Full HD has 1920x 1080=2,073,600 pixels; 8K TV has 7,680×4,320=33,177,600 pixels. he “K” in 8K stands for Kilo (1000), meaning a TV that has achieved a horizonal resolution of about 8,000 pixels.

Although we can define a LCD display with resolution, a Full HD resolution on screen size of a 15” monitor or a 27” monitor will show different. The screen “fineness” is very important for some application, like medical, or even our cell phone. If the display “fineness” is not enough, the display will look “pixelized” which is unable to show details.

DPI stands for dots per inch and refers to the resolution of a printer. It describes the density of ink dots placed on a sheet of paper (or another photographic medium) by a printer to create a physical print.

PPI stands for number of pixels per inch. It is kind of pixel density. PPI describes the resolution of a digital image, not a print. PPI is used to resize images in preparation for printing

But you see other lower resolution available, that is because video cards are doing the trick. A video card can display a lower LCD screen resolution than the LCD’s built-in native resolution. The video cards can combine the pixels and turn a higher resolution into lower resolution, or just use part of the full screen. But video cards can’t do the magic to exceed the native resolution.

Abbreviation: QVGA, VGA, HD, FHD, 1080p, 1440p, 4K etc. It is very straight forward for different applications. For TV buyers, they can simply focus on 4K, 8K etc; for industrial engineers, they most likely focus on VGA, HD, WVGA etc.

Aspect Ratio:  You might hear 4:3 which is full screen, 16:9 is for widescreen; 21:9 is for ultrawide computer monitors and televisions, as well as cinematic widescreen projectors. Some ultrawide monitors are trying to replace dual monitor.

A TFT LCD,  or a thin film transistor liquid crystal display, is one of the fastest growing forms of display technology today. The thin film transistor (TFT) is a type of semiconductor device used in display technology to enhance efficiency, compactness, and cost of the product. In conjunction with its semiconductor properties, the TFT LCD is an active matrix display, controlling pixels individually and actively rather than passively, furthering the benefits of this semiconductor device.

The TFT LCD is built with three key layers. Two sandwiching layers consist of glass substrates, though one includes TFTs while the other has an RGB, or red green blue, color filter. The layer between the glass layers is a liquid crystal layer.

The Architecture of a TFT Pixelbelow) from the other substrate layer of the device and control the amount of voltage applied to their respective sub-pixels. This layer also has pixel electrodes between the substrate and the liquid crystal layer. Electrodes are conductors that channel electricity into or out of something, in this case, pixels.

On the surface level is the other glass substrate. Just beneath this glass substrate is where the actual pixels and sub-pixels reside, forming the RGB color filter. In order to counteract the electrodes of the previously mentioned layer, this surface layer has counter (or common) electrodes on the side closer to the liquid crystals that close off the circuit that travels between the two layers. In both these substrate layers, the electrodes are most frequently made of indium tin oxide (ITO) because they allow for transparency and have good conductive properties.

The outer sides of the glass substrates (closest to the surface or closest to the back) have filter layers called polarizers. These filters allow only certain beams of light to pass through if they are polarized in a specific manner, meaning that the geometric waves of the light are appropriate for the filter. If not polarized correctly, the light does not pass through the polarizer which creates an opaque LCD screen.

Between the two substrate layers lie liquid crystals. Together, the liquid crystal molecules may behave as a liquid in terms of movement, but it holds its structure as a crystal. There are a variety of chemical formulas available for use in this layer. Typically, liquid crystals are aligned to position the molecules in a certain way to induce specific behaviors of passing light through the polarization of the light waves. To do this, either a magnetic or electric field must be used; however, with displays, for a magnetic field to be usable, it will be too strong for the display itself, and thus electric fields, using very low power and requiring no current, are used.

Before applying an electric field to the crystals between the electrodes, the alignment of the crystals is in a 90 degree twisted pattern, allowing a properly crystal-polarized light to pass through the surface polarizer in a display’s “normal white” mode. This state is caused by electrodes that are purposely coated in a material that orients the structure with this specific twist.

However, when the electric field is applied, the twist is broken as the crystals straighten out, otherwise known as re-aligning. The passing light can still pass through the back polarizer, but because the crystal layer does not polarize the lights to pass through the surface polarizer, light is not transmitted to the surface, thus an opaque display. If the voltage is lessened, only some crystals re-align, allowing for a partial amount of light to pass and creating different shades of grey (levels of light). This effect is called the twisted nematic effect.

The twisted nematic effect is one of the cheapest options for LCD technology, and it also allows for fast pixel response time. There are still some limits, though; color reproduction quality may not be great, and viewing angles, or the direction at which the screen is looked at, are more limited.

The light that passes through the device is sourced from the backlight which can shine light from the back or the side of the display. Because the LCD does not produce its own light, it needs to use the backlight in the OLED) have come into use as well. Typically white, this light, if polarized correctly, will pass through the RGB color filter of the surface substrate layer, displaying the color signaled for by the TFT device.

Within an LCD, each pixel can be characterized by its three sub-pixels. These three sub-pixels create the RGB colorization of that overall pixel. These sub-pixels act as capacitors, or electrical storage units within a device, each with their own independent structural and functional layers as described earlier. With the three sub-pixels per pixel, colors of almost any kind can be mixed from the light passing through the filters and polarizer at different brightness based on the liquid crystal alignment.

While buying a television, computer or a mobile, you would have come across the term TFT and wondered what it really meant. Simply put, TFT stands for “Thin Film Transistor”.

It is a type of LCD flat-panel display screen, wherein each pixel is controlled by one to four transistors. Also known as active-matrix LCDs, TFT technology offers the best resolution of all the flat-panel techniques. However, that makes it one of the most expensive ones too.

TFT transistors are normally used in high-quality flat-panel LCDs. Such displays come with at least one transistor for each pixel on the screen. This makes it possible for the electrical current that illuminates the display to be turned on and off quicker. This, in turn, results in brighter display and smoother motions. LCDs with TFT technology are active-matrix displays and are higher-quality than the older passive-matrix displays. Active matrix simply means that every pixel is attached to an individual transistor and capacitor.

So, the next time you see a label TFT AM LCD monitor at your local computer store, don’t be baffled. It simply means that the monitor comes with a “thin-film transistor active-matrix liquid crystal display”. In other words, it is an excellent flat-screen monitor. Good colours make everything look brighter and more appealing.

The advent of LCDs made viewing a better experience than ever. Soon, a world of high-end colour LCD Modules became the preferred choice. But thanks to the technological evolution of embedded devices, more and more sophisticated products and designs came into being.

Design is no longer about what things look like and feel like. Design is more about how it works. As such, the TFT LCD modules on our TV, computer monitors, kindles, mobile phone and navigation systems are all excellent designs. They are not only highly effective but also add to the look and feel of the devices.

Less energy consumption – because of the construction of TFT structures with pixel-like materials, they do not consume too much energy, to begin with. When compared with the CRT monitor, the TFT monitor consumes far less power and is therefore a preferred choice.

Sharper visibility with superb visual quality - the images displayed on a TFT display do not rely on scanning the electron beams. Hence they are flicker-free and offer a crisp image, with no geometric distortion.

Excellent physical design – the physical design of TFT display is in such a manner that they save a lot of space. The devices can be placed anywhere in the office or home even if there is very little space available.

Faster response time – as there are individual transmitters and conductors, the response time is much faster than that of the normal LCD or CRT displays. There is virtually no delay in turning on the screen, which makes it preferable to other types of displays.

Low strain on the eye – thanks to the quality of pictures displayed and the absence of any rays emitting from the screen, viewing is rather pleasant and strain-free for the eyes.

Poor viewing experience at angles – TFT screen offers the best viewing experience right at the front. Any change in the angle of view could mean a distorted view. Still, TFT displays are far superior in quality than the older versions and would be expected to improve in the future.

Technology is ever-changing. So it is no wonder TFT is also undergoing frequent changes. For instance, now you have IPS. It stands for In-Plane Switching and is a further improvement on TFT LCDs.

Although energy consumption is low compared to TFT LCDs, and they are better than TFT LCDs, they are more expensive. But IPS TFT LCD technology is now widely used for high-performance computers, laptops, tablets, and smart phones.

As a display device TFT stands for Thin Film Transistor and is used to enhance the operation and usefulness of LCD displays. An LCD is a fluidic display device that uses a crystalline filled liquid to manipulate a rear illumination polarized source by means of an electrostatic field between two thin transparent metal conductors such as indium tin oxide (ITO) in order to present an image to the viewer. This process can be used in both segmented or pixelated display devices but is found synonymous with color TFT displays.

When an LCD is used to display moving images the inherent slow rate of change between fluid states over a large number of pixel elements can be a problem due in part to capacitive effects, which causes moving image blurring. By putting a high speed LCD controlling device in the form of a thin film transistor right at the pixel element on the glass surface, the LCD image speed issue can be greatly enhanced and for all practical purposes eliminates image blurring.

Other benefits of these thin film transistors are they allow for thinner display designs and different pixel designs and arrangements to vastly improve display viewing angles.

TFT displays are found in many applications these days, from mobile devices, appliance, medical devices, instrumentation, aircraft and certainly computer display devices as well as TV’s. The addition of the thin film transistor in LCD design vastly improved the use of LCD’s in all market areas.
