An improved method of arrangement for the cells comprising the pixels of a display device wherein each of the pixels includes a brightest cell, a bright cell, a medium cell and a dark cell. The brightest cell and the bright cell are aligned substantially parallel to one the display axes and the bright cell and the dark cell are diagonally aligned with respect to the axes of the dipslay.

Provided is an electrostatic sensing chuck for attracting particles to a portion of a particle contact surface near a deposition electrode, the electrostatic sensing chuck comprising a pixel comprising: a deposition electrode (DE) for selectively establishing an attraction field (Ea) at the particle contact surface; a shield electrode (SE) oppositely biased with respect to the deposition electrode; a charge sensing circuit to measure charge accumulated on each of the deposition electrode and the shield electrode, wherein the charge sensing circuit subtracts a second charge it senses at the shield electrode from a first charge it senses at the deposition electrode, thereby determining accumulated charge at the deposition electrode balanced by accumulated charge at the shield electrode.

A light-emitting fiber comprises an optical fiber having a number of light-emitting elements disposed along the length of one surface thereof. The light-emitting elements include a segmented hole injecting electrode on which an electro-luminescent material, such as an OLED material, is disposed and an electron injecting electrode overlying the OLED layer. The segmented hole injecting electrodes are connected together by an electrical conductor disposed on a side surface of the optical fiber. Electrical contacts connect to the electron injecting electrode and are disposed, at least in part, so as to not overlie the OLED layer. The electrodes, OLED material and contacts are deposited on the optical fibers by mask deposition, preferably utilizing masks adapted to contemporaneously process a plurality of fibers.

A display device, such as an LCD, has alignment layers made of different materials; thus one layer can have a low curing temperature so as not to cause damage to delicate organic layers, such as a color filter, during curing, while the other layer can have a larger tilt angle so as to minimize ambiguities in the liquid crystal material.

An incident light beam illuminates the surface of a disc, having signal elements recorded therein in the form of a succession of spaced apart depressions, with a light spot that spans a plurality of depressions. The structure of the depressions serves as a diffraction grating which reflects the incident light beam into a plurality of substantially coplanar diverging fans of light. Polarizers are interposed between the light beam source and the surface to polarize the light beam in orthogonal directions. Photodetectors, positioned to intercept the reflected fans, provide outputs corresponding to the light power in the reflected fans. The photodetectors provide a first output of the reflected light power of the light beam polarized in a first direction and a second output of the light power of the reflected light beam polarized in a direction orthogonal to the first direction. The ratio of the first output to the second output is indicative of the depression depth.

Groove depth estimation apparatus provides an incident light beam which illuminates the surface of a grooved disc with a light spot that spans a plurality of convolutions of the groove. The structure of the groove convolutions serves as a diffraction grating which reflects the incident light beam into a plurality of diverging beams of light. A photodetector provides measurements of the light power in the respective reflected beams. Calculator circuits are provided for deriving from the photodetector measurements estimation of the average groove depth in the region illuminated by the light spot.
摘要:
A number of light-emitting fibers in side-by-side array comprise a display. Each fiber includes a number of light-emitting elements disposed along the length of one surface of an optical fiber, such as an electro-luminescent material, e.g., an OLED material, disposed between hole injecting and electron injecting electrodes. Contacts on the top ones of the electrodes are connected by a conductor disposed transverse to the longitudinal direction of the fiber. The conductors are preferably deposited on the optical fibers by mask deposition, preferably utilizing masks adapted for contemporaneously depositing a metal conductor across a plurality of fibers. Electronic circuits having patterned conductors corresponding to the transverse conductors may be connected thereto by solder, conductive adhesive and the like.
摘要:
A keel-tipped stylus for playback of video information from a disc record is formed on a lapping disc having a spiral signal track on the land between a spiral lapping groove. The respective pitches of the signal track and groove are different whereby the signal track and lapping groove cross each other. A playback stylus riding in the groove will detect a signal from the track to monitor the lapping process.
摘要:
A video disc record suitable for use with a video disc player apparatus is provided with a label for identifying the program material stored on the surface of the record. The label is formed in a machine readable format which comprises grooves in the surface of the record. In one format, whorls of a spiral groove on the surface of the record are spaced alternately with ungrooved areas on the surface. A readout apparatus comprises a light beam which is arranged to scan the grooved label and a detecetor which is arranged to sense the light beam reflected from the disc record surface. Light striking an ungrooved section is reflected in a substantially specular direction while light striking a grooved section is substantially scattered out of the specular direction. The detector is arranged to collect the light reflected into the specular direction.
