Add some jazz & pizazz to your project with a color touchscreen LCD.
This TFT display is big (3.5" diagonal) bright (6 white-LED backlight)
and colorful! 480x320 pixels with individual RGB pixel control, this
has way more resolution than a black and white 128x64 display, and
double our 2.8" TFT. As a bonus, this display has a resistive
touchscreen attached to it already, so you can detect finger presses
anywhere on the screen.
This display has a controller built into it with RAM buffering, so
that almost no work is done by the microcontroller. The display can be
used in two modes: 8-bit or SPI. For 8-bit mode, you'll need 8 digital
data lines and 4 or 5 digital control lines to read and write to the
display (12 lines total). SPI mode requires only 5 pins total (SPI
data in, data out, clock, select, and d/c) but is slower than 8-bit
mode. In addition, 4 pins are required for the touch screen (2
digital, 2 analog).
Of course, we wouldn\'t just leave you with a datasheet and a "good
luck!". Check out our detailed tutorial for wiring, test and example
code!  For 8-bit interface fans we\'ve written a full open source
graphics library that can draw pixels, lines, rectangles, circles,
text, and more . For SPI users, we have a library as well , its
separate from the 8-bit library since both versions are heavily
optimized. We also have a touch screen library that detects x, y and z
(pressure)  and example code to demonstrate all of it.
* 3.5" diagonal LCD TFT display
* 320x480 resolution, 18-bit (262,000) color capable - our code uses
only 16-bits since its faster.
* HXD8357D controller with built in video RAM buffer
* 8 bit digital interface, plus 4 or 5 control lines (12 pins
minimum) or SPI mode with 4 or 5 SPI data/control lines (4 pins
minimum) - not including the touch screen.
* 5V compatible! Use with 3.3V or 5V logic such as an Arduino
* Onboard 3.3V @ 150mA LDO regulator
* 6 white LED backlight with DC/DC constant-current boost. You can
PWM dim the backlight
