12864b parallel serial graphic lcd module quotation
The 12864B Graphic LCD module is a 128 x 64 pixel LCD display with a blue backlight and white foreground. The display is fully programmable and can display a combination of both graphics and text. It can operate in both parallel and serial (SPI) modes which can be configured by the external pin PSB. In SPI mode only 3 data pins are required to drive this display. No potentiometer is required to set the contrast as this is pre set by the factory to optimum level.

This module is engineered for high volume production. It uses a "TAB" (tape automated bonding) or "COF" (chip on flex) style flex tail mated with a "COG" (chip on glass) display. The TAB connector is soldered directly to corresponding pads on your PCB using a hot-bar soldering machine. High volume contract manufacturers will be familiar with this type of construction and its assembly methods. Hot-bar soldering machines designed for prototype, rework or repair of TAB connections are available from equipment suppliers at reasonable cost.
As we have already said, we will use two operation modes, parallel and serial communication. In order to make writing of the code easier, we will use libraries (one is ST7920 GFX Library which is based on the well-known Adafruit GFX Library (check the instructions for Adafruit GFX library here), only for now it does not support parallel communication, and the other is U8G library which supports both serial and parallel communication, but is somewhat more complicated to handle). If you do not know how to install libraries, we advise you to check our tutorial about it.
First we will deal with the ST7920 GFX Library, so open Arduino IDE, then FIle->Examples->ST7920_GFX_Library->ST7920_graphic_test and upload the code to Croduino. If everything is fine, the display will show the test program for display. If that does not happen, check the connections.
Now let"s make something a bit more complicated, and that is a very simple clock (it will not be too accurate because counting seconds is based on Arduino"s millis(); function, but it is great for the example how to make display of the clock on the graphic display).
Now that we have tried out serial communication, we will try out the parallel one using u8g library. The advantage of this library is the fact that it uses very little RAM, so it can be adapted into some more complex projects. But, this is also a drawback, because it is significantly slower than the ST7920 GFX Library. Library"s instructions (along with all the functions it uses) can be found here.
AL12864C is a 0.96 inch graphic OLED display module run by 128x64 dots through parallel/ serial interface such as 8-bit 68xx-Series, SPI and I2C. This OLED module features high contrast (10,000:1), wide viewing angle, wide operation temperature (-40ºC to +70ºC) and the thinness thanks to the organic light-emitting diode, which lights up itself and thus there"s no need for additional LED backlight.
