tft lcd pin configuration price

※ Price Increase NotificationThe TFT glass cell makers such as Tianma,Hanstar,BOE,Innolux has reduced or stopped the production of small and medium-sized tft glass cell from August-2020 due to the low profit and focus on the size of LCD TV,Tablet PC and Smart Phone .It results the glass cell price in the market is extremely high,and the same situation happens in IC industry.We deeply regret that rapidly rising costs for glass cell and controller IC necessitate our raising the price of tft display.We have made every attempt to avoid the increase, we could accept no profit from the beginning,but the price is going up frequently ,we"re now losing a lot of money. We have no choice if we want to survive. There is no certain answer for when the price would go back to the normal.We guess it will take at least 6 months until these glass cell and semiconductor manufacturing companies recover the production schedule.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!".Here is the link for5" TFT capacitive touch shield with libraries,examples,schematic diagram for Arduino Due,Mega 2560 and Uno. For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and development kit at the bottom of this page.

A 2.4” TFT LCD module consists of a bright backlight (4 white LEDs) and a colourful 240X320 pixels display. It also features individual RGB pixel control giving a much better resolution than the black and white displays. A resistive touch screen comes pre-installed with the module as a bonus and hence you can easily detect your finger presses anywhere on the screen.

The TFT comes with an auto-reset circuit which gets active on every breakout. However, a user can reset the module using this pin also, in case setup is not resetting clean.

Resistive Touch Pins – Y+, X+, Y-, and X- are the 4 resistive touch pins which require analog pins to read and determine touch pins. Their overlay is fixed at the top of the module which makes them electrically separate from the TFT. They can be used is 8-bit as well as SPI mode.

The 2.4” TFT LCD module supports many modes. However, two of them are very popular among users – “SPI mode” and “8-bit mode”. The display contains pins on both sides required for a mode and a user can switch easily between them by simply rewiring the display. It should be noted that only one mode can be used at a time.

The 74LVX245 chip is responsible for interfacing the display with MCU/MPU; it provides fast level shifting so that the user can work on both the logic levels. All the pins are 3.5V logic level compatible. However, if there is an output, the level goes at 3.3V.

A 2.4” TFT module has a very flexible usage. It is compatible with all your DIY projects where you want to add a bright, colourful, and touchscreen enabled display.

The SparkFun TFT LCD Breakout is a versatile, colorful, and easy way to experiment with graphics or create a user interface for your project. With a 4-wire SPI interface and microSD card holder, you can use this breakout to easily add visual display/interface capabilities to a project as well as providing all the storage you might need for multimedia files.

To get started with this breakout, you will need an Arduino compatible microcontroller of your choice - we recommend something with extra RAM like the SparkFun Thing Plus. The breakout can be powered with either 5V or 3.3V. The microSD card holder is connected to the same SPI bus as the display which keeps the required pin count low and exists to relieve the burden from your microcontroller"s poor memory due to having to store hundreds of images of cats, or really whatever you want to keep there. We have also gone ahead and tricked out the SparkFun HyperDisplay library with a driver made especially for this breakout!

Out of the box, the SparkFun TFT LCD Breakout will come with a large backing PCB that makes it easy to securely mount the display in a project. If you need a more flexible solution you can remove the display module, snap off half the backing board, and then re-insert the display module. When this is done you"ll be left with the bare minimum frame around the display to more seamlessly integrate with your project.

2.4” TFT LCD Module is one of the most common RGB color display modules. Therefore,  this module offer different applications from conventional display modules in features and usage. It offers multi-way communication protocols to the developers/designers. This TFT module is not popular only because of its color screen, it has a resistive touch on itself. The touch screen is accessible by microcontrollers and they are controllable by the users according to the requirements.  Additionally, it can display up to 240×320 pixels on a single screen. Even images can also show on the screen. It is mostly available in developing projects and low-cost devices only.

The pin configuration of the module is simple like other display devices. The only problem is the developers need to understand first which method is better to operate the TFT LCD display. Therefore, the TFT touch screen uses the diver to operate each pixel and the driver uses a small no of pins as input and makes it user friendly. The pin configuration is as follows:

These all pins from D0~D7 are the digital data input pins. It requires only when a developer needs to work with LCD using 8-bit data or using Assemble language. The Arduino library mostly uses the SPI pins.

The LCD screen is made up of three types of pixels at a single point. The LCD uses the two polarized layers to pass the layer but both layers are opposite in pattern to each other. The liquid crystals relate to anode and cathode which makes the liquid crystal change their angle which helps to change the angle of light. The change in angle allows the light to pass from the polarized layers. There is always a total combination of three colors of pixels which are known as RGB. The intensity of pixels is controllable and helps to manage each pixel. The change in intensity changes the angle of the crystals and which makes the output light according to the image or text requirement.

Each pixel in the LCD needs to control according to the requirement individually. There are a driver ILI9341 which can control each pixel with the small no of pins which we already discussed above. In LCD the driver also attached to the Arduino shield. The Arduino shield comes with simple input pins but the driver output pins which are the most important pin. These pins are the source and gate driver pins. The source pins are 720pin and the gate pins are 320pins. The driver has an internal GRAM that stores the data each time the microcontroller send to it. The data on the display screen always temporary and stay in the GRAM until it needs to show to the screen. The following block diagram shows the internal structure of the driver ILI9341:

The LCD is useable with Arduino but it depends on the library. The library is compatible with Arduino only and compatible with the attached shield. To use the library first attach the LCD on the Arduino UNO or attach it by connecting wires on the other Arduino. Here’s the Arduino Uno with TFT shield:

The above libraries will help but to use the LCD first describe the LCD pins attached to the Arduino. It is changeable with the requirement of the LCD use. There are other libraries which can perform different functions which the above library unable to perform. There is some no of pins that need to describe.

The initialize the LCD in the Arduino setup. To initialize the LCD always remember it could give some errors. To avoid errors, use the reset commands.

The following command will make the whole screen black because the use of white color on the screen won’t show the data on the screen. So always define the screen fill color to describe the screen. The usage of the image is only most of the time with images and text. Every function on the LCD needs to change from the display command only but the rest of the data will be the same on the LCD. The internal SD card solves the memory issue.
