摘要:
A method and apparatus for communicating image data. In one embodiment, the method comprises transmitting, by a computer comprising at least one processor, (i) an initial encoding of a first image instance of a first spatial tile in a sequence of image frames followed by (ii) an initial encoding of a second image instance of the first spatial tile; transmitting, by the computer, an encoding indicative of a perfect match between pixel values of a first image instance of a second spatial tile in the sequence and the first image instance of the first spatial tile; and transmitting, by the computer, an initial encoding of a second image instance of the second spatial tile based on receiving an indication of an absence of a decoding of the encoding of the first image instance of the first spatial tile.

A method and system for forming filter elements on a plurality of display substrates using a digital imaging system operable to selectively deposit filter material at a plurality of deposition locations is disclosed. The method involves receiving orientation information defining a disposition of a plurality of pixels associated with the at least one display substrate, identifying pixels in the plurality of pixels that are to receive filter material for forming a filter element on the pixel, selecting deposition locations within each of the identified pixels in accordance with the orientation information to meet an alignment criterion associated with placement of the filter element within the pixel, and controlling the digital imaging system to cause deposition of the filter material at the selected deposition locations. A method and system for forming filter elements on a substrate is also disclosed, which involves selecting locations to receive filter material for forming filter elements on the substrate, introducing a random variation in placement of the filter elements, and forming filter elements at the selected locations, the substrate being subsequently aligned to a display substrate for forming a display. A method and system for forming filter elements on a display substrate is also disclosed, which involves selectively depositing filter material to form the filter elements on a plurality of pixels associated with the display substrate, and selectively exposing the deposited filter material to thermal laser radiation to condition the deposited filter material.
摘要:
A pattern of non-contiguous features that can be imaged in one pass of a multi-channel imaging head is divided into sets of the non-contiguous features. Each set of the non-contiguous features is imaged separately during a single scan of the multi-channel imaging head. The pattern can be completely imaged after all of the sets have been separately imaged. The non-contiguous features of one set may be interleaved with the non-contiguous features of another one of the sets.
摘要:
Methods are provided for imaging patterns on a media. The steps of the method include operating a first imaging head with individually addressable channels to direct imaging beams to form a first image on the media while scanning over the media along a scan path. A second imaging head with individually addressable channels is operated, either at the same time or a different time, to direct imaging beams to form a second image on the media while scanning over the media along a second scan path. It is possible that the first scan path may or may not be parallel to the second scan path, and that the first image may or may not be aligned with the second image. The first image may or may not be skewed with respect to the second image.
摘要:
An imaging system is equipped with two or more exposure heads that are each able to image either a separate media sheet or a portion of a single media sheet loaded on a media carrier. The imaging time for any combination of media sheets is minimized by providing for the adjustment of the spacing between the dual exposure heads whenever the media configuration changes. In imaging a unitary image using two exposure heads to each image a sub-image, any discontinuity between the end of the first sub-image and the start of the next sub-image is reduced by changing the traversing speed of one of the exposure heads by a fractional amount.

An apparatus (10) for adjusting the calibration of an imaging system to correct for geometric distortion comprises a rotating drum for receiving recording media (17), a plurality of carriages (18) each having an imaging head (16) with a plurality of addressable imaging channels, and a controller programmed with a lookup table, analytical relationship or algorithm that relates corrective adjustments to be made to the imaging of a given imaging head based on the positions of others of the imaging heads. A method is described for obtaining the lookup table, analytical relationship or algorithm. The method has particular relevance to large imaging systems.
摘要:
A method is provided which includes operating a first multi-channel imaging head to direct imaging beams along a scan path to transfer a first non-contiguous feature and a second non-contiguous feature from a donor element to the receiver element by a thermal transfer process. The first and second non-contiguous features are spatially separated from one another at least in a sub-scan direction. The method also includes operating a second multi-channel imaging head to direct imaging beams to direct imaging beams to transfer a third non-contiguous feature from the donor element to the receiver element by the thermal transfer process. The third non-contiguous feature is between the first and second non-contiguous features and is spatially separated from each of the first and second non-contiguous features at least in the sub-scan direction.
