1 128x64 COG Graphic Modules CI Description IDS have introduced an unprecedented array of technologies and backlight colours to enhance your product design. Utilising our 128x64 COG module, designers can now have the flexibility to develop a product with the style and look they need, including an RGB option. We also support this product with Arduino and Pi code, breakout boards and demos to make implementation as quick as possible.

2 Accessories Break-Out Board We have designed a break-out board for our CI xx range of standard COG displays. The IDB-CI xx-xx. enables our CI xx COG displays to be used with the industry standard 0.1 header, with all secondary components added, only the important connections are brought out. Development System We have designed a development system to make choosing and developing with our displays as simple as possible. Images are loaded via an SD card in a simple bitmap format, with on board controls of time between image, contrast, brightness and touch control (where applicable) you can within minutes start to see what your application will look like on the target display.

Cautions for use Take utmost care when handling as these products are made of glass. Any strong mechanical impact due to falling, etc. may cause damage(breakage or cracking). Polarizer is made of soft material and is easily damaged, take utmost care when handling. The protective film attached is to prevent scratch and protect against dirt, it is recommended that this film should be kept sealed before use. Clean polarizer with a soft cloth. Do not touch the connection terminals of the display with bare hand, it will cause disconnection or defective insulation of terminals Avoid use or extended storage at high temperature and high humidity. For extended storage, select a storage area where the temperature is 20±8 C and the relative humidity is less than 65% Do not expose the display to the direct sunlight or UV light. Be careful not to touch or swallow liquid crystal that might leak from a damaged cell. Any liquid crystal will adhere to skin or clothes, wash it off immediately with soap and water.
