I2C 128 X 64 Graphic Display with 21 Character x 8 line Text
** This is a very bright and clear display **
The BV4219 is a graphical LCD display that has blue pixels on a white background. The 128 x 64 pixels can be individually switched on or off producing blue graphics on a white background or white graphics on a blue background. In addition to this the I2C controller provides a text interface giving a display that is capable of displaying 21 characters over 8 rows. Text and graphics can be mixed to produce a comprehensive display system.
The display is controlled by simple I2C commands over a two wire interface thus considerably reducing component count and interface complexity. There is built in line, box, pixel and text drawing commands reducing the complexity of the software interface.
NOTE: This display will work without a back light as the dark characters can still be seen with it switched off.
Above is an example of mixed text and graphics.
This shows the full character set from ASCII 0x32 to ASCII 0x7F.
* Simple command set for direct interface to LCD module
* 21 characters by 8 lines giving a total of 168 displayable characters
* Box drawing functions, with or without fill.
* Size 95mm wide, 70mm tall and 23mm deep including interface board
* 42mA with BL on, 10mA with it off
The interface is attached to the back of the board and provides a simple I2C connection.
