Kent Display - 320x240x5.7

Replacement: None. We do not have a direct replacement for this LCD. This page is for reference only.

This is a 320x240 reflective cholesteric liquid crystal display (ChLCD) from Kent Displays. The most distinguishing feature of a ChLCD is its ability to retain its image even when the LCD is not powered, similar to e-ink technology. This makes the LCD a great fit for portable battery-powered projects. Bistable, sunlight readable, and easy to integrate, this 320x240 (1/4 VGA) is truly a unique LCD display solution.

Integrated into the display is an embedded controller which generates the unique ChLCD drive waveforms and provides automatic temperature compensation. Communication with the controller is achieved through an SPI-compatible interface, which means a minimal number of I/O resources are needed to control the display.

We now have a breakout board compatible with this display's connector here.

These screens may show traces of pressure points from handling. Don't worry, it's not broken. This can be easily corrected with an electronic erase. The datasheet discusses how to do this on page 8, under section 4.4 Electronic Erase (Pressure Point Removal)
