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 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.
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.
Backlight intensity is usually controlled by varying a few volts DC, or generating a PWM signal, or adjusting a potentiometer or simply fixed. This in turn controls a high-voltage (1.3 kV) DC-AC inverter or a matrix of LEDs. The method to control the intensity of LED is to pulse them with PWM which can be source of harmonic flicker.
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.

I was writing about the best cameras for under $300, which I listed in another post. While writing, for some reason, I googled, “what is the most expensive camera ever?” And that’s how I started my research.
I’m a tech nerd, and I’m in love with beautifully designed and high-end technology pieces. I like to read their spec, understand their value and why they cost so much. In this article, you’ll find a list of some of the most expensive cameras that would make anyone flinch.
This camera is not exactly something you can buy, and I’m listing it for the most curious out there. It’s a rare camera for collection and not something that has real commercial use. The most expensive camera in the world is the Leica 0-series no. 122 and it sold for a world-record $2.97M in 2018 at a Leica auction in Vienna, becoming the most expensive camera ever.
The M3D-2 was manufactured for war photojournalist David Douglas Duncan. He was famous for his war photos in Korea, Vietnam, and for his work with his friend Pablo Picasso. Only four types of the Leica M3D existed, all produced for David Douglas Duncan. The camera was sold at Westlicht Auction for over USD 2,000,000.
This example of Leica Luxus 1, dating from circa 1930, auctioned for the massive price of $1,300,000 at the WestLicht Auction in 2012. The reasons for the astronomical price are the rarity of the camera (only 95 examples were produced between 1929 and 1930) and the original gold plating and lizard skin body.
In the medium format realm, Phase ONE XF IQ4 is the most expensive camera on the planet. The full-frame medium sensor delivers an incredible 151MP file in astonishing detail.
The Hasselblad H6D-400c offers 400 million pixels, which are undeniably the highest count in the industry. With such a powerful camera, one can capture even the finest details in an image.
The Panoscan Mark III MK-3 is able to scan a 360 degree image in one single shot. This $40,000.00 piece of technology is among the top most expensive cameras ever and it’s used to produce standard flat panoramas or 360 degree images for virtual reality players.
The Hasselblad H6D-100c is an upgrade of the H6D-50c. Instead of offering 50 megapixels, the camera comes with a 100 Megapixels CMOS sensor that allows you to explore your imagination, for sharper, better quality images.
The Hasselblad H6D-50c is a quality camera that every professional photographer must-have. From its weight to its overall look, this camera promises to deliver stunning images beyond expectations.
The Leica S body itself costs more than $20,000. This 37.5-megapixel jewel of engineering by the Swiss manufacturer is a medium format camera with a slightly smaller sensor than normal. Characteristic that helps keeping the price “low” if compared to the most expensive Hasselblad cameras.
The Hasselblad X1D-50c boasts of a bigger sensor than any other camera within its class, consequently translating to larger photosites and a wider, dynamic range.
The Pentax 645z is the perfect choice for medium-format photographers. The camera is comparatively larger than a typical DSLR, and it comes with a Sony CMOS sensor for excellent image quality.
The Sony a7R IV camera offers outstanding imaging capability, coupled with high-speed performance, for the ultimate power, precision, and flexibility required for professional shooting needs.
The Nikon D5 is an FX-format DSLR camera that exhibits massive advancements in sensor technology, metering, autofocus and image processing. The camera boasts of precise AF detection, tracking, and high-speed continuous shooting for better image quality.
The Z6 is an upgrade of Nikon’s DSLR cameras. The camera features a fast and silent Live View autofocus, in-body stabilization and a 10-bit N-log output for grading flexibility and extra quality.
The Canon 5D Mark IV needs no introductions, given that it is one of the most recognizable digital cameras. It comes with dozens of features engineered to perform in every situation.
The Leica CL is the ideal camera for street photography, thanks to its excellent build quality and unique technical features. The camera consists of fine-grain leather, a magnesium chassis, aluminum black anodized top, and bottom plates.
The Leica 24 SL Type 601 is a premium camera that has a high level of build quality, weather sealing, a high-resolution viewfinder and effective controls for various shooting needs.
