摘要:
An optically dispersing film for a rear projection system includes reflecting surfaces disposed so as to reflect light passing therethrough into at least one dispersion plane. The reflecting surfaces are formed by structures, of a first refractive index, disposed within a layer of material having a second refractive index. The structures have light absorbing bases at the viewing side of the film. In some embodiments, the reflecting surfaces are disposed at one or more angles so as to reflect light into a number of different directions. In other embodiments, the layer of material having the second refractive index includes diffusing particles that diffuse the light. The film permits the asymmetric dispersion of image light in a rear projection system, so that the light may be selectively directed towards the viewer.

Disclosed is a rear projection screen that includes a plurality of tapered waveguides and a light absorbing layer disposed over the tops of the waveguides, but that does not completely fill the spaces between the waveguides, thereby forming an interstitial low index region under the light absorbing layer and between the waveguides. The low index interstitial region can include air or a material that has a lower index of refraction than the waveguide material. This rear projection screen construction can give rise to increased efficiency and higher contrast, as well as allow for more design freedom in constructing screens that have desired characteristics such as viewing angle, viewing asymmetry, and the like. Also disclosed are methods for making the described microstructured rear projection screen.
摘要:
A method of selectively patterning a structured substrate without using a mask is disclosed. The method includes the steps of providing a surface having a plurality of protrusions, coating the surface with a filler material thick enough so that the protrusions are covered, and planarizing the filler coating. The filler material is thereafter partially removed in a uniform fashion to expose only those portions of the protrusions to be modified. After modifying the protrusions by, for example, deposition or etching, the remaining filler material may be removed, resulting in a structured substrate selectively modified or patterned at its protrusions.
摘要:
A beaded light dispersing film has a substrate layer, and an optically transparent layer, having a predetermined thickness, disposed over a side of the substrate layer. Optically transmitting beads are arranged to penetrate at least partially into the transparent layer to define clear apertures at interfaces between the beads and the transparent layer. The bead radius is greater than the predetermined thickness. An absorbing layer is disposed on the transparent layer, in interstices between the beads. A method of manufacturing the film includes disposing optically transparent beads partially in an optically transparent layer disposed over a transparent substrate layer. The optically transparent layer has a thickness less than half a diameter of a transparent bead. An absorbing layer overlies the optically transparent layer.

Substrate elements for making liquid crystal display devices are disclosed as well as display devices using such elements. A substrate element includes a base sheet having the desired optical properties and providing the structural stability for the substrate element. The substrate element further includes a microstructured barrier layer that protects the base sheet from adverse chemical reactions with the liquid crystal or alignment layer solvents. The microstructured barrier layer comprises a plurality of microstructured spacing members that provide precise, uniform spacing between the first substrate element and a second substrate element. A pair of substrate elements, at least one of which having a microstructured barrier layer, can thereby be mated to form a display device. The substrate elements of the present invention allow large area, high resolution displays to be fabricated which will provide uniform display properties throughout the display area.

A black matrix can be formed by thermal transfer on a receptor substrate for use, for example, in a display application. This black matrix can be used, for example, as a color filter black matrix or a TFT (thin film transistor) black matrix to provide contrast and/or to separate adjacent electrically-conducting components.

An improved electronic display that includes components selected to enhance display performance. The improved display includes an active substrate that has a plurality of thin film transistors and a plurality of thermally transferred color filters that include a colorant in a crosslinked binder. The active substrate can also include a black matrix. Other components in the improved display such as a liquid crystal material, spacers, and bottom polarizer, can be selected to enhance display performance characteristics such as brightness, power consumption, response time, weight, and thickness. The invention also provides a method of forming a color filter substrate for displays including the steps of thermally mass transferring a plurality of color filters and crosslinking the plurality of color filters after transfer. Before the crosslinking step, the plurality of color filters can be inspected and removed for reworking of the substrate.
