Reflective displays projection

CLAIMS BIBLIO iacludes an abstract and claim ia additioa to basic bibliographic information for chemical and chemically related U.S. patents from 1950 and for all patents from 1963. AH claims are searchable and ptintable from 1971 claims for many patents are not avaHable from 1971 to 1974. Prom 1972, many tides have been enhanced with additional keywords to describe the iavention more clearly and to iadicate the presence of a drawiag chemical stmctures have beea coaverted so that they display ia linear format. Many company names have been standardized, and USPTO classification is updated aimuaHy to reflect reclassification projects. 

Cholesteric LCs can act as hosts for dyes to produce coloured displays (see section 5.2.2.1 below) " their temperature dependent colour change has found applications in thermochromic inks, °" and as pigments and copy safe colours their selective reflecting capabilities have been applied in colours and filters for reflective displays and projection systems, " reflective polarisers and their electrical field induced switching in displays and smart reflectors, in colour patterning for full-colour recording. ... 

For direct-view reflective displays, the outmost surface reflection (usually it is a plastic protective film without anti-reflection coating) limits the device contrast ratio. Thus, the -100 1 contrast ratio of the 75° MTN is still adequate. However, in projection displays the contrast ratio needs to exceed 1000 1. The 90° MTN and the VA cells are the better choices. 

A "PC projection panel" and overhead projection of the spreadsheet greatly eases viewing of the computer video output. The PC projection panel provides an overhead projection of the computer screen so that all review team members can easily and simultaneous observe and comment on the recorded information as it is being recorded. The PC projection panel consist of a liquid crystal display (LCD) panel that duplicates data, text or graphics, generated from the computer screen. When placed on an overhead projector the LCD image is projected onto a projector screen or a wall. Personal computer screens are viewable by only two or three personnel at a time. A typical review involves at least 5 personnel, so the PC projection pad enables all participants to view the software worksheet as it is prepared (note a "reflective" type of overhead projector will not operate with the PC projection panel, direct illumination from below the panel is required). Further details of a typical PC projection panel are provided in Appendix F. 

Figure 2.18 (a) The regular orbit of T[, symmetry as an elliptical projection and (b) in perspective displaying the structure as a modified small rhombicuboctahedron, in which there is no reflection symmetry across face diagonals of the inscribing cube. 

Figure 3.7 The general spherical harmonics in the range 0 < I < 4 displayed as elliptical projections on the unit sphere. The shadings in the diagrams reflect areas on the unit sphere of positive function amplitude. 

Figure 3.8 The cr-type group orbitals on the vertices of an O3 structure orbit exhibiting D31J point symmetry displayed on the elliptical projections of Figure 3.7. The circular icons, filled and open circles, identify cr-oriented orbital components at the vertices, sized to reflect the coefficients of the linear combinations, equation 3.20, for the spherical harmonics in Table 3.11. The icons and identify the distinct group orbitals transforming as the irreducible components of the reducible character over the decorated orbit, unnecessary repetitions of these components and central functions for which no group orbital can be constructed owing to the locations of the decorated vertices of the orbit in the Cartesian coordinate system.
