320x240 lcd display module graphiic COB — 320 x 240 dot graphic LCD modules in COB construction with an RA8835 controller and a white LED backlight, the largest monochrome dot matrix in this range and a standard QVGA format for existing monochrome HMIs.

FAQ
Can a small microcontroller drive a 320x240 monochrome display?
Yes, because the RA8835 holds the display RAM on the module. A 320 x 240 monochrome frame is 9600 bytes, which an 8-bit MCU could never buffer internally, but it only has to send drawing commands rather than refresh the panel.
Why choose a monochrome 320x240 instead of a colour TFT?
Monochrome COB modules stay readable in direct sunlight without a high brightness backlight, draw far less power, and keep working over a wider temperature range, which suits outdoor and battery powered instruments.
Is the 320x240 a QVGA screen?
Yes, 320 x 240 is the same QVGA pixel format as a colour TFT of that size, so layouts and bitmaps created for a QVGA colour panel can often be reused in monochrome.
Can the 320x240 be supplied with a touch panel?
A resistive or capacitive touch panel can be added, along with custom backlight colours and a wide temperature build.
