A variety of methods for driving electro-optic displays so as to reduce visible artifacts are described. Such methods includes driving an electro-optic display having a plurality of display pixels and controlled by a display controller, the display controller associated with a host for providing operational instructions to the display controller, the method may include updating the display with a first image, updating the display with a second image subsequent to the first image, processing image data associated with the first image and the second image to identify display pixels with edge artifacts and generate image data associated with the identified pixels, storing the image data associated pixels with edge artifacts at a memory location, and initiating a waveform to clear the edge artifacts.

Electro-optic displays, and methods for driving same

A temperature regulation system includes a laminate material that has a first light transmissive electrode layer, a rear electrode layer, and a bistable electrophoretic medium disposed between the first and second electrode layer. The electrophoretic medium includes two types of particles that have different charges and color. The amount of incident radiation (visible light, infrared, etc.) that is absorbed by the laminate can be modified by providing a voltage between the electrode layers.

A variety of methods for driving electro-optic displays so as to reduce visible artifacts are described. Such methods includes updating a display having a plurality of display pixels with a first image, identifying display pixels with edge artifacts after the first image update, and storing the identified display pixels information in a memory. In particular, the methods are effective for minimizing edge ghosting when a pixel of an active matrix electrophoretic display undergoes a white to white transition or a black to black transition during an update between first and second images.

Methods for driving electro-optic displays

A bistable electro-optic display has a plurality of pixels, each of which is capable of displaying at least three gray levels. The display is driven by a method comprising: storing a look-up table containing data representing the impulses necessary to convert an initial gray level to a final gray level; storing data representing at least an initial state of each pixel of the display; receiving an input signal representing a desired final state of at least one pixel of the display; and generating an output signal representing the impulse necessary to convert the initial state of said one pixel to the desired final state thereof, as determined from said look-up table. The invention also provides a method for reducing the remnant voltage of an electro-optic display.

Methods for driving bistable electro-optic displays, and apparatus for use therein

A pixel of an electrophoretic display is driven from one extreme optical state to a second optical state different from the one extreme optical state by applying to the pixel a first drive pulse of one polarity; and thereafter applying to the pixel a second drive pulse of the opposite polarity, the second drive pulse being effective to drive the pixel to the second optical state.

Methods for driving electrophoretic displays

A backplane for use in an electro-optic display comprises a patterned metal foil having a plurality of apertures extending therethrough, coated on at least side with an insulating polymeric material and having a plurality of thin film electronic devices provided on the insulating polymeric material.
