Fast and Interruptible Drive Scheme For Electrosphoretic Displays
First Claim
1. A method for displaying an image on a bi-stable display device based on image data received thereat, the method comprising:
- receiving a first portion (605) of the image data at the display device (500);
driving each of a plurality of pixels (2) of the display device to an associated first optical state (632) that is defined by the first portion;
receiving a second portion (606, 607) of the image data at the display device; and
driving each of the plurality of pixels to an associated second optical state (636) that is defined by the first and second portions.

Abstract
An image update scheme for an electrophoretic display reduces driving delays while allowing display of a reduced quality image when driving is interrupted. A first portion (605) of image data is transmitted to a display device (500) such as from a mobile network device (400). The first portion may include the MSB of a data word for each pixel. Each pixel (2) is driven to an associated first optical state (632) that is defined by the first portion. A second portion (606, 607) of the image data is subsequently received at the display device, and each pixel is driven to an associated second optical state (636) that is defined by the first and second portions. In another approach, the second portion includes a substantially complete representation of the image, and each pixel is driven to an associated second optical state (636) that is defined by the second portion.
