US Patent:

20130050986, Feb 28, 2013

Filed:

Aug 23, 2011

Appl. No.:

13/215786

Inventors:

Reuven Rahamim - St. Louis Park MN, US
John Souter - Wayzata MN, US

International Classification:

G02F 1/13357
H01L 33/08

US Classification:

362 971, 438 34, 257E33067

Abstract:

An apparatus comprises a display backlight having a substrate and a plurality of light-receiving channels formed in that substrate. At least some of these channels have a depth that varies as a gradient along a longitudinal axis of the channel that is substantially axially aligned with a light-receiving input for the channel. These channels can be formed substantially parallel to one another. The aforementioned light-receiving inputs can, if desired, be formed at either end of each such channel and can be disposed inwardly of an edge of the substrate. Also if desired, at least some of these channels can be disposed other than at an orthogonal angle with respect to such substrate edges. So configured, light rays that orthogonally enter the light-receiving inputs will have an opportunity to contact the edges of the channels and be reflected outwardly of the channel to provide the desired backlighting effect.

Appl. No.:

8/501502

Inventors:

Christopher J. Edge - St. Paul MN
John Souter - Orono MN

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

H04N 146

US Classification:

364526

Abstract:

A system and method for color characterization and transformation obtain color data representing output of a color imaging system, and convert the color data using a color space having a white reference vector that is adjusted during the conversion. The white reference vector can be adjusted according to intensities of the color data being converted. Adjustment of the white reference vector serves to avoid nonuniformities for color imaging systems having different imaging bases, and thereby eliminates, or at least reduces, the amount of empirical adjustment necessary to obtain an acceptable visual match between the color imaging systems.

Appl. No.:

8/911555

Inventors:

Ranjan C. Patel - Little Hallingbury, GB2
John Souter - Orono MN

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

G03F 7038
G03F 734
G03F 736

US Classification:

430201

Abstract:

A color reproduction method is described using laser addressable thermal transfer donor elements which may be used to image both color proofing films and printing plates. Matched proofs and plates may be generated by direct digital address since identical transfer media are used in the respective imaging processes. In addition, each plate bears a resin image of a color that matches the color of the ink that will be used with that plate thus providing a convenient means of identification. In other words, the identity of each plate (i. e. whether it bears the y, m, c or k separation image) is immediately apparent by visual inspection, thus removing any risk of confusion and any need to provide individual plates with identification marks.

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

G03C 1495
G03C 152
G03C 168
G03C 184

US Classification:

430158

Abstract:

Presensitized sheets for color proofing comprising a removable carrier sheet bearing a photosensitive medium sensitive to radiation within the wavelength band 325 to 700 nm and comprising photohardenable, photoadherent, photoinsolubilisable or photosolubilisable material, the sheet including a removable antihalation layer which is removed either when stripping the carrier sheet or during subsequent processing. The antihalation dyes may be positioned within a transparent carrier sheet, in a layer on the carrier sheet opposite to the photosensitive medium or in a layer positioned between the carrier sheet and light-sensitive medium.

G03F 740

US Classification:

430200

Abstract:

A laser-induced thermal imaging system having a donor element and a receptor element. The donor element includes a substrate on which is coated transfer material that includes: a binder including a hydroxylic resin; a fluorocarbon additive; a cationic infrared absorbing dye; a dihydropyridine latent crosslinking agent; and a dispersible material. The receptor element comprises a texturized surface.
