Partial Update Technology Speeds Up and Enhances User Experiences of E-Paper Displays

TAINAN CITY, Taiwan, September 14, 2016 /PRNewswire/ --

    Pervasive Displays (PDi), a world leader in e-paper displays today announced the
availability of partial update display driving technology across its range of electronic
ink e-paper displays (EPD). E-paper is a bistable technology, which means that energy is
only consumed when the display is changing. Once it has changed, the display consumes no
energy and continues to show information, even when disconnected from its power
source. Rather than update the whole display image when part of it changes, known as a
global or full update, a partial update (or local update) only refreshes the pixels that
need to be changed. This approach greatly enhances the user's visual experience since it
does not create the blinking effect typically associated with a global update when all
pixels are refreshed. In addition, this method of update takes less time and consumes much
less power, further improving the user's visual interaction with the display. A partial
update cycle takes around 300 - 600 ms which is a quarter of the time typically required
for a global update on a similar monochrome display. The partial update uses two data
buffers to contain the current and new images, and by comparing these, the pixels that
require updating are identified.

    The partial update display driving technology has been integrated into the graphics
libraries of the semiconductor vendors supported, these including Texas Instruments (TI)
and Microchip. Examples of application areas for this type of technology are smart home
devices such as thermostats and home appliances; Internet of Things (IoT) applications
like alarm systems, sensor devices and public information boards; and personal devices
such as name badges, healthcare devices and electronic bag tags.

    A video example [http://www.pervasivedisplays.com/kits/ext2_kit#PartialUpdate ] of the
partial update being used on a variety of different display sizes with external timing
controllers (eTCs) from PDi is available on the Pervasive Displays website together with
the source code for use with the new EPD Extension Kit.

    PDi has also implemented partial update with the TITM TivaWare Graphics Library (grlib)
for its internal timing controllers (iTC) driver displays. Demo videos
[http://www.pervasivedisplays.com/kits/ext2_kit#PartialUpdate ] are available on the
website for thermostat, human machine interface (HMI) and smart home applications.
Developers can obtain the new EXT2 Kit from Pervasive Displays to preview the partial
update effect on full images using displays with iTCs.
