Bistable display is a non-traditional display method. It is a display device illuminated by reflecting ambient light. The image is retained on the display even after the panel power supply is removed. Bistable display offers paper-like readability with features such as high contract, a wide viewing angle, reflective, and readable under sunlight. It is ultra thin and lightweight. Som bistable displays can even be twisted out of shape. Moreover, they system power can be saved by bistability characteristics, since the image remains on display even without power.
 

Solomon Systech developed the specialized Bistable Display Driver Controllers SSD1615 and SSD1621 to make this novel display technology become a reality. These highly integrated drivers consist of MCU interface for command and image data input, display RAM to buffer image data, high voltage driving outputs. To minimize the system cost and space, the drivers have built-in DC/DC converter to supply high voltage to drive bistable display. These drivers can be applied to different bistable displays technology such as Cholesteric and Electrophoretic displays.

Applications: 

Electronic shelf labels, electronic signs, digital clocks and watches, smart cards, electronic books, etc.
