- Generate high-quality images in less power
- Provides adequate space for any external application circuitry
Pervasive Displays (PDi), a developer of e-paper displays, has launched a range of Aurora black and white e-paper, or E-ink, electrophoretic displays (EPDs). These chip-on-glass (COG) front plane laminate (FPL) displays incorporate the latest driving waveform technology for producing sharp images in a thin design, leaving plenty of room for installing additional electronic circuitry and battery.
Thanks to their bi-stable functionality, EPDs have revolutionized the options for applications that require monochrome displays. To keep the total power consumption at an absolute minimum, only updating the display’s image requires power. This makes them ideal for applications where the content of the display changes irregularly, such as digital signs, retail spaces, office automation, building navigation, reusable badges and healthcare.
Such solutions can also be battery powered and in places like shelves, doors and windows, or devices that are not fixed in place.
Wide temperature range
The Aurora Ma (V230) range of EPDs support operating temperature range of over -25 degrees Celsius to 10 degrees Celsius. The Aurora Mb (V231) EPDs support 0 degrees Celsius to 50 degrees Celsius and Aurora -25 (V430) EPDs support -20 degrees Celsius to 50 degrees Celsius range while providing resolutions of between 100 and 140 dots-per-inch (DPI).
A one-time programming (OTP) option also allows predefined images to be recalled without the need for long data transfers from a host CPU. For a 3V supply voltage, updating an image requires less than 5mA for a 212 x 104 pixel ESD at around 2 seconds.
For providing a less costly option for solutions using EPDs, some products (in the range) have their timing controller (Tcon) and booster circuitry. This helps to minimize the external circuitry required to interface with the display to reduce the total bill-of-materials (BOM) and simplify the required software programming. For full flexibility, EPDs with an external Tcon are also available but may require an optional boost circuit.
The full range of EPDs from 1.44 to 12.2 inch are available with immediate effect through the company’s distribution partner DigiKey.
