Add a LCD screen to your next Arduino project. The Arduino Graphic LCD (GLCD) screen is a backlit TFT LCD screen with headers. You can draw text, images, and shapes to the screen with the GLCD library. There is an onboard micro-SD card slot on the back of the screen that can, among other things, store bitmap images for the screen to display.
The screen's headers are designed to fit into the socket on the front of the Arduino Esplora, but it is compatible with any AVR-based Arduino (Uno, Leonardo, etc. Datasheet You can use this module with Arduino Esplora. To connect the screen to other Arduino boards, read the tutorial on this link.
Colors
The screen has the ability to show 16-bit color. The red and blue have 5-bits of resolution each (32 levels of red and blue), the green has 6-bits of resolution (64 different levels). For consistency with other applications, the library deals with color in 8-bit values for the red, green, and blue channels (0-255), and scales the colors appropriately.
NOTE: If you expensive 4-5 thick white/black line when using the LCD screen, it is due to a compatibility issue. Arduino changed one of the controllers on the LCD board recently (in all products that use the LCD), and this was incompatible with their LCD library. A fixed TFT Library is included in the nightly build of the 1.5.4 IDE. You can download this here: http://arduino.cc/en/Main/Software#toc4
