This is Sainsmart 2.4 inch TFT LCD module with the TFT LCD shield kit for arduino enthusiasts.It includes one piece of 2.4 inch TFT LCD display and a TFT LCD shield for Arduino MEGA2560 (R3).We will provided you the whole document including the example project of arduino due with the kit. We will supply you the technical support after your purchase.

Voltage type: 5v or 3v voltage input voltage,input is selectable. Because TFT can only work under 3.3 V voltage, so when the input voltage VIN is 5V, need through the 3.3 V voltage regulator IC step down to 3.3V , when the input voltage of 3.3 V, you need to use the zero resistance make J2 short , is equivalent to not through the voltage regulator IC for module and power supply directly.(Click here)

It is 100% compatible with the normal MCU like ARM AVR PIC and 8051,especially on arduino family such as arduino due and arduino mega2560(R3).The module uses the LCD controller Chip SSD1963 with 5 inch LCD including the touchscreen.

The shield defines that all the the data transmit ports are PC1-PC8 and PC12-PC19,the controll pins are PD0-PD3.The perfect design could realize that the data transmits in high speed.The SPI interface is designed in the ISP header of arduino due so that the SPI transfer with DMA could be achieved in high speed with no drag.

The 2.4 inch TFT LCD Touch Display Shield is a Bright, 4 white-LED backlight, on by default but you can connect the transistor to a digital pin for backlight control. So spice up your Arduino UNO project is a beautiful large touchscreen display shield with a built-in microSD card connection. This TFT display is big (2.4″ diagonal) bright (4 white-LED backlights) and colorful (18-bit 262,000 different shades)!

2.4 inch TFT LCD Touch Display Shield for ArduinoUno is fully assembled, tested and ready to go. Add the touch display without wiring, no soldering! Simply plug it in and load up a library – you ‘ll have it running in under 10 minutes! Works best with any classic Arduino ATMEGA328 Board.

The 2.4 inch TFT LCD Touch Display comes with 240×320 pixels with individual pixel control. It has way more resolution than a black and white 128×64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

With four bright white LED backlight and 240 x 320 pixels with individual RGB pixel control, this colour 2.4in. TFT display features a resistive touchscreen for fingertip detection across the entire screen surface. The workload is lifted from the microcontroller by a built-in controller equipped with RAM buffering, and the display board has two modes: 8-bit and SPI.

I found the TFT screen and Uno on Banggood.com about a month ago and over the weekend I was messing with the pair and found the tftbmp draw code in the demo.. I extended it with the ability to read any bmp file on the SD card.. so all you do is put your bitmaps on the SD and plug it in.. Having to add/edit/recompile/reload the Uno everytime is BS... Here is my code:

Just tested the 2.2″ version. Easiest way to control it from an Arduino is by using the Adafruit ILI9340 library. Made a video of the example sketch that comes with the library: http://www.youtube.com/watch?v=bVzZ6PWFbGE

Thanks for the feedback, I have tested it on 5V, it seems no problem for testing, for the LED backlight it has to be 3V3, or 5V with 10K resistor, for the VCC, not sure which have to be used. It seems the factory provided info it not fully promising.

The 2.2″ version is perfect for displaying complex information due to the 320×240 pixel area. Power consumption is reasonable. Be aware of the 3.3V levels since 5 volts will destroy your display (sooner or later). Most ARM boards will come with 3.3V levels anyway and even Atmel ATmega will work on 3.3 volts (but with lower frequency)

nice unit. got the 2.2″ version for my signal generator project (based on the AD9850 module i got from here also). clean and clear, very happy with it.. got it working with a couple of different libraries, mainly Adafruit and UTFT.

Have not yet tried 2.4”, but if you tried different libriies and it does not work, then you try to use a pro mini 3v3/8m, because some models of this series need 3v3 logic.

2.2” – Nice colors, easy integration with Arduino Uno and Teensy++2.0 . Only 3 stars because of the limited angle of view and issues withh the edge most lines.

There are many tutorials on Arduino shields for 2.4 inch TFT LCD displays. In this road test I apply different tutorials to check the performance and issues of this specific shield: AZ-Delivery 2.4 inch TFT LCD display with resistive 4-wire touchscreen and an integrated SD card reader.AZ-Delivery 2.4 inch TFT LCD display.

TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology. That improves image quality, better contrast and addressability.

Depends on the needs of your project. Arduino UNO processor frequency is low. With the Arduino UNO full-color TFT LCDs are suitable to display simple data and commands. The TFT controller used cannot switch internal display RAM, so you can"t use the double buffer technique for animations but still you can only re-draw small sections of screen.

This module consumes most of the resources available in Arduino UNO. This is not a limitation of the module itself. In return, using a parallel interface allows you to quickly update the image. If you want to take advantage of all its functionality (LCD + touch screen + SD card), only pins 0 and 1 (RX and TX, respectively) and pin 19 (A5) remain unused. If the SD card is not used, pins 10, 11, 12 and 13 are additionally available. With a suitable layout, some SPI devices could be connected even if the SD card is used.

The module arrived well packed and in perfect condition. The board comes in a sealed antistatic bag, with protective foams to prevent the terminals from bending, and all this wrapped with a bubble bag and inside an individual cardboard box. The label on the antistatic bag indicates the controller is an ILI9341.

The PCB silkscreen indicates the main function of each pin, the labels are easy to read, although it does not show labels for the touch screen pins:Pin 9 - Touch X+ / LCD_D1

The SD card reader is very well located between the USB connector and the power connector, it does not touch either of them as it happens in other lcd tft shield modules and it is easily accessible to insert and remove the SD cards.

You can directly use the shield with any arduino uno. In this case we are using an Arduino UNO that exposes all the pins both on the header and on the board. In such a way that you do not need another shield to access the pins not used by the screen

ShieldCompatible with Arduino. 5V compatible, can be used with 3.3V or 5V logic. On-board 3.3 V (300mA LDO controller). The design is very well thought out and fits Arduino UNO perfectly.

2x74LVC245A Octal Bus Transceiver With 3-State outputs. This octal bus transceiver is designed for 1.65-V to 3.6-V VCC operation. The LVC245A is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses effectively are isolated. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment. This chip solves the problem of how to interface 3.3V logic devices to a 5.0V logic chip such as the Arduino. Most 3.3V devices do not like being run with 5V signals and can be damaged or flaky. The 74LVC245 is designed so that even when it runs at 1.8V, it still happily accepts 5V signals in one pin and converts it to a lower logic level on the opposite pin. It has 8 pipes it can convert but it won"t work with bi-directional/pull-up based devices such as I2C or 1-Wire. It does work great for SPI, Serial, Parallel bus, and other logic interfaces.

If you want to take advantage of all its functionality (LCD + touch screen + SD card), only pins 0 and 1 (RX and TX, respectively) and pin 19 (A5) remain unused. If the SD card is not used, pins 10, 11, 12 and 13 are additionally available. With a suitable layout, some SPI devices could be connected even if the SD card is used.

The ILI9341 which can control each pixel with a small number of pins. The shield connects ILI9341"s data pins 0-7 to Arduino digital pins 2-8 (allowing parallel communication, not SPI). ILI"s RESET goes to pin to Arduino analog pin A4.CS (chip select) to A3. RS (CD command/data) to A2. WR and RD to A1 and A0.

Includes a resistive 4-wire touchscreen (touchpad). The touch screen is attached on the surface of the display. Touch screen needs two analog inputs and two digital outputs. It connects through 4 wires, which share arduino pins 8, 9, A2, A3 with the ILI9341 driver. So you can"t write to LCD display and read the touch screen in the same time. I. Driver chip is XPT2046.

The optical characteristics are good, with a wide color gamut and good sharpness. The viewing angle is quite wide and there is no color inversion or other flaws. The screen is brilliant. Colors are bright enough to read the screen well even in daylight.

The resistive touch screen does not appear to appreciably affect the optical characteristics. Works properly, It takes a little pressure with the stylus for it to respond like in old mobile phones. You notice how it sinks into the screen when you press with the stylus. The stylus that comes with the module makes it easy to use if your interface design uses small controls. Some touch screen libraries offer better accuracy by specifying the resistance of the touch screen in the X direction. Resistance can be easily measured with a multimeter by connecting the test leads to the LCD_D1 - X + and LCD_DS X- terminals. Touch is sensitive to pressure.

The SD card reader works well. Accessing the SD card with the functions available in the SD library included in the IDE version used does not present any problem. SD cards are recognized and can be written or deleted.

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.

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.

IPS has since been superseded by S-IPS (Super-IPS, Hitachi Ltd. in 1998), which has all the benefits of IPS technology with the addition of improved pixel refresh timing.

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.

A technology developed by Samsung is Super PLS, which bears similarities to IPS panels, has wider viewing angles, better image quality, increased brightness, and lower production costs. PLS technology debuted in the PC display market with the release of the Samsung S27A850 and S24A850 monitors in September 2011.

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.
