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.

Digimax distribetes a wide range of professional LCD monitors and large format displays for digital signage applications manufactured by Philips: one of the world"s largest manufacturers of TFT monitors, recognized for quality products and cutting-edge solutions.

Mitsubishi Electric"s thin-film-transistor liquid-crystal display (TFT-LCD) modules are built for a wide variety of industrial uses, such as for measuring instruments, automatic teller machines (ATM), point of sale terminals (POS), factory automation equipment (FA) and more. Designed for high reliability, optimal visibility,read more...

There are different components of a TFT displays that can be modified to create a custom color LCD. Some of the modifications are not too expensive, while others can be cost prohibitive. We will cover some of the main options available and their estimated cost when customizing a TFT display module.

Note: If you need a color LCD module, but do not need video or dot matrix (Graphical) capabilities, I would suggest using a lower cost alternative such as FSC*(Field Sequential Color display) aka known as a TN color display. A second option for a lower cost and much lower power requirement would be a custom segmented display module with color overlays.

This is by far the most expensive component of the TFT module to customize. There are industry standard glass sizes for TFT’s. The list includes, but is not limited to, 2.8 inch, 3.5 inch, 5.7 inch, 7 inch, 10.2 inch and larger. If you can design your product to make use of these standard sizes, then do it. If you need a unique size, say a something between a 2.8 inch and 3.5 inch, you may be forced to invest in a custom glass size. We have seen quotes for custom glass sizes for TFT run between $100,000 dollars to $150,000 dollars. Not a minor investment for most companies.

A TFT LCD display with a modified PCB, is still considered a custom color TFT. Modification costs to customize the PCB is an estimated $400 to $1,200 one-time tooling fee. The unit cost of the TFT display, with a modified PCB will be slightly higher than the cost of the TFT with a standard PCB.

Many products that incorporate a custom color LCD display will contain a touch screen or touch panel. These can be modified to meet a customer’s particular size for an estimated tooling cost of $3,000 to $4,000.

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.

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.

Initial iterations of IPS technology were characterised by slow response time and a low contrast ratio but later revisions have made marked improvements to these shortcomings. Because of its wide viewing angle and accurate color reproduction (with almost no off-angle color shift), IPS is widely employed in high-end monitors aimed at professional graphic artists, although with the recent fall in price it has been seen in the mainstream market as well. IPS technology was sold to Panasonic by Hitachi.

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.

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.

Hello everyone to my new tutorial in which we are going to program arduino for tft lcd shield of 3.5" with ILI9486 driver, 8 bit. I found it important to write this tutorial as if we see we find tutorial for 1.44, 1.8, 2.0, 2.4, 2.8 inch shields however there are no or less tutorials available for 3.5" shield as its completely different from other smaller tft lcd shields -adafruit tft lcd library doesn"t even support ILI9486 driver in 3.5" tft lcd, it supports drivers of tft shields lesser then 3.5"

Go through the above link to know better, lets start with our tutorial however if we can"t use Adafruit_TFTLCD library which library will we use ?, there"s a simple answer to this that"s MCUFRIEND_kbv library which helps to use 3.5" tft lcd shield, if you see this library makes it much more easier to program arduino for tft lcd shield than adafruit as we have to simply create a tft object in MCUFRIEND_kbv library and then using that we can control the tft lcd shield however in Adafruit_TFTLCD library we will have to create the object and also define connections which makes it a very long task.

Once added, create the tft object using library name and a name for object, you can also define some color codes for text which we are going to type, using the define function and giving color code. This all is to be done before setup.#include#include#define BLACK 0x0000#define RED 0xF800#define WHITE 0xFFFFMCUFRIEND_kbv tft;

Its time to now start our tft lcd screen and change the background, this is to be done by using some simple functions by obtaining the tft ID and changing the background bytft.fillScreen("color_name");void}

Now we will be programming in loop for printing text on TFT LCD shield, for that we will be using a number of functions such as -tft.setCursor("x","y");x means the position from the x axis on screen and y means position from the y axis on screen of tft lcd shield.tft.setTextSize("number");number here refers to text size which take parameter as number you can give any number from 1 according to your requirements.tft.setTextColor("color");color here means to give the color name we had defined before setup, this makes the text color as whatever you give.tft.print("value");value is nothing but what you want to print, whatever you give as value must be in double quotes.void loop() {// put your main code here, to run repeatedly:tft.setCursor(0,0);tft.setTextSize(3);tft.setTextColor(WHITE);tft.print("my first project with tft -");tft.setCursor(0,70);tft.setTextSize(2);tft.setTextColor(RED);tft.print("welcome to the world of arduino and display , myself I love arduino and game programming very much. This is why I have my own youtube channel in which I share my arduino projects and games made by me , isn"t it amazing !");}

Graphics which we see in our phone is combination of square, rectangle, circle, triangle, lines. This is why here we will learning how to draw the following shapes.tft.drawRect(x,y,width,height,color);x means the position from the x axis of the screen, y means the position from y axis of the screen, width refers to set the width of rectangle, height refers to set the height of the rectangle and color means the color of rectangle you want it to be. You can use this same function by simply keeping the height and width same.tft.drawCircle(x,y,radius,color);x means the position from the x axis of the screen, y means the position from y axis of the screen, radius is a para to set the radius of circle and color means the color of circle you want it to be.tft.drawTriangle(x1,y1,x2,y2,x3,y3,color);x1, y1, x2 etc. are to set the position of triangle"s three points from which lines are drawn.tft.drawLine(x1,y1,x2,y2,color);x1 and y1 are to set point 1 from which line is made to point 2 which is set by x2 and y2.

I have shown we can draw text and shapes by which we can make various graphics, you can also refer to code given by me, one is for text and other is for graphics display.
