What is a screen key? It's the child of a programmable LCD, programmable RGB LED, and a nice tactile switch. The RGB24T can be programmed to display any text or graphics on its 36 x 24 pixel display (SK Interfaces Ltd). The programmable backlight can illuminate the graphic display with many different colors. With a simple microcontroller, you can change the display and backlight once the button is pressed. It's an on-the-fly configurable, multicolor, multidisplay button!
