Liquid Crystal Display on Glass is the newest in LCD technology. The display is very compact, it measures 55x27 mm and the height is only 2mm without LED backlight and 5.8mm with LED backlight. The display's can have different LED background light instead of only the green and blue of the normal LCD modules.
There are 5 monochrome colors available: white, green/yellow, blue, red, amber and there is even a full color RGB background possible. The contrast of the display can be set with a command. This is done using software. The display's series consists of 3 types. This is the figure of the circuit.
The display and the corresponding backlight are clipped together and inserted into a PCB and soldered. The display has a build-in character set of 248 europe and japannese characters, in addition you can also define 8 characters. The integrated controller, the ST7036, has build in commands to control the display. In this project the display is connected to an AVR AT2313 microcontroller.
For the ease of use it has designed a small PCB. The board has two rows of 20-pins socket connectors, in which the display can be inserted, it has also a resistor to limit the current through the background LEDs. For connection with the microcontroller the board has a 5x2-pin connector, so the board can easily connected to the STK500 board or to the AT2313 project board with a 10-pole flat cable. In this project the 4-mode is used so there are only 4 data lines and 2 control lines.
