摘要:
A method is disclosed in the context of a system comprises an electrophotographic subsystem, a transfer subsystem, an imaging member, and an inking subsystem. The electrophotographic subsystem comprises a photoreceptor, a charging subsystem, an exposure subsystem, and a development subsystem. In operation, the photoreceptor is charged areawise. An exposure pattern is formed by the exposure subsystem on the surface of the charged photoreceptor to thereby write a latent charge image onto the photoreceptor surface. The image is developed with an image defining material, such as a dampening fluid. The image defining material forms a negative pattern of the image to be printed. This negative image is then transferred to the reimageable surface. The negative image is then developed with ink. The inked image may be transferred to a substrate.

An apparatus (20) for directing electromagnetic radiation into a respective pupil of at least one eye of a user is disclosed. The apparatus comprises first radiation emitting means comprising at least one radiation emitting layer (8) adapted to emit electromagnetic radiation and second radiation emitting means (6} adapted to direct electromagnetic radiation into at least one eye and/or onto at least one eyelid of a user. A light guide (1) is adapted to receive radiation emitted by the first radiation emitting means and to direct at least part of the radiation to the second radiation emitting means, wherein a total surface area of the first emitting radiation means from which radiation is emitted is larger than a total cross sectional area of a beam of radiation entering the or each pupil of the user in use, in a direction transverse to an optical axis of the beam.

A display device having a hybrid drive including a substrate, a two-dimensional pixel array formed on the substrate, the pixels associated into a plurality of pixel groups. A separate set of group row electrodes and group column electrodes are connected to pixels in pixel groups, so that a single group row electrode together with a single group column electrode drives a single pixel. Two or more chiplets are located over the substrate within the pixel array, each chiplet associated with a pixel group and having connections to each of the associated group row electrodes and associated group column electrodes and having storage elements, the storage element storing a value representing a desired luminance for a pixel and the chiplet using such value to control the desired luminance of each pixel in its associated pixel group.
