This display module from 4D systems is the uLCD-70DT, a 7.0” intelligent touchscreen LCD powered by the DIABLO16 graphics processor. The uLCD-70DT is designed for applications demanding a large intelligent display module, and is the largest size available from 4D Systems.
The DIABLO16 Processor offers considerable FLASH and RAM upgrades over the PICASO processor, and also provides mappable functions such as I2C, SPI, Serial, PWM, Pulse Out, and Quadrature Input, to various GPIO, and also provide up to 4 Analog Input channels. The uLCD-70DT also features 2mm pitch male headers to connect an optional module. 4D Systems intends to bring out one or more modules which will be compatible with the uLCD-70DT, offering connectivity such as WiFi or Bluetooth. This will enable the uLCD-70DT to connect with remote devices.
Note: A power supply of 5V, 1A-2A is recommended.
The Arduino library for this display can be found here.
Using the Workshop 4 software to compile and upload through the serial-to-USB converter, you can write a message and draw shapes on the 7" touchscreen. If you are using a different 4D touchscreen, make sure to change your platform. The ViSi environment was used for this example.
#platform "uLCD-70DT" #inherit "4DGL_16bitColours.fnc" func main() gfx_ScreenMode(LANDSCAPE) ; // Orientation //print("Hello World") ; //Simple Print Statement var rad, colour; repeat //Main Loop rad := 5; while(rad < 60) colour := RAND(); gfx_Circle(90, 74, rad, colour); gfx_Rectangle(5, 5, rad, rad++, BLUE); gfx_Line(90, 74, 20, rad, RED); rad := rad + 8; pause(20); wend forever //End of Main Loop endfunc

The default firmware for this display can be found on 4D's product page here.
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

Although it is pricey, this display gets the job done. I have used it's smaller 3.2 and 4.3 inch brothers on other projects. I am making this one with a connector on a cable so it can be used on multiple projects.
I am dissapointed that you are not carrying the matching bezel for this screen, which is confusing because you carry them for the other sized screens.

The only little annoying thing is the fact that you have to connect and disconnect your uSD from your computer in order to load the program in the touchscreen. Other thing, is that you have to pay extra for the license of the software with convenient features for the programmer, I think that if you spend $180 in a touchscreen at least they have to give a one computer license
I was able to get a project up and running very quickly at work with this screen. Easy to use and program with their software package. Graphics are nice. I like using it so much I bought a 4.3" for myself. I wish it could be a kitted with the bezel, stand, Arduino adapter, and any cables needed.
This module is the greatest. It's easy to connect and program. 4D systems knows how to make a high quality product and provides the necessary software tools to support it. On a scale from 1 to 10, I give it a 12:)
Last year I bought more than 15 Display Module - 7" Touch screen LCD and .. 2 moth back I got 3 LCD ine of them have fault its not working alsy 8 month back I got some LCD one of that also same Issue there is 2 Screen Now have fault what shall I do ?? Best regards upul
