128x32 graphic lcd module made in china
Monochrome 128x32 I2C OLED Graphic Display is small, only about 1" diagonal, but very readable due to the high contrast of an OLED display. This display is made of 128x32 individual white OLED pixels, each one is turned on or off by the controller chip. Since the display makes its own light, there is no need for backlight. Therefore the power required to run the OLED is reduced and contrast of display is increased.
The power requirements depend a little on how much of the display is lit but on average the display uses about 20mA from the 3.3V supply. There is a detailed tutorial and also an example code by Adafruit in the form of Arduino library for text and graphics. Since the display needs to be buffered, you will need a microcontroller with more than 512 bytes of RAM.
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 thin display. The TAB connector must soldered directly to corresponding pads on your PCB using a hot-bar soldering machine, or bonded with anisotropic adhesive using heat and pressure. 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. The TAB style connection requires no separate connector, so the cost is very low, and the ultra thin profile of the display is maintained.
