    Abstract: An optical system, including a reflective polarizer, and a display and a mirror disposed on a same side of, and generally facing, the reflective polarizer. The reflective polarizer may transmit at least 80% of incident light having a first polarization state and may reflect at least 80% of incident light having a second polarization state, and the mirror may reflect at least 80% of the incident light for each of the first and second polarization states. The central locations of the display, reflective polarizer, and mirror may define a midplane which includes first, second, and third regions, such that the first region includes portions of the image rays that pass at least once across the region, the second region includes portions of the image rays that pass at least twice across the region, and the third region includes portions of the image rays that pass three times across the region. The first, second, and third regions may have respective areas A1, A2, and A3, such that A3/A2 is greater than or equal to about 0.20, or 0.22, or 0.24, or 0.26, or 0.28, or 0.30.

    Abstract: A composite article having a conductive layer on at least a portion of a flexible substrate. Electrical connectivity between various portions of the substrate can be obtained through this conductive layer. The conductive layer comprises a conductive surface, and there is a patterned layer on at least a portion of a first region of the conductive surface. The patterned layer comprises a conductive material having a surface roughness, and is in electrical contact with the conductive surface. An overcoat layer is present on at least a portion of the first region, such that the overcoat layer has a thickness less than the surface roughness, such that the conductive layer within the first region is covered by the overcoat layer, and such that at least a portion of the patterned layer substantially protrudes above the overcoat layer. The protruding portion permits electrical contact with the patterned layer, and via the conductive layer to other parts of the patterned layer and/or electrically conductive connectors to external electronic devices. Methods for forming the composite article are also disclosed. Methods of making such composite articles are also disclosed.

    Abstract: An optical system includes a display, a reflective polarizer, and a glare trap. The glare trap includes a plurality of slats having a length L and a width W, L/W ≥ 10. The slats form a plurality of elongated slots therebetween substantially filled with air. The reflective polarizer has an average optical reflectance of at least 40% for a first polarization state and an average optical transmittance of at least 40% for an orthogonal second polarization state. For each of the first and second polarization states, the glare trap has an average specular optical transmittance of between about 20% to about 80% and an average total optical reflectance of less than about 20%. For at least one wavelength in the visible wavelength range, an optical transmittance of the glare trap includes a first transmittance peak at a first peak angle with a corresponding FWHM of less than about 30 degrees.

    Abstract: An optical system includes a reflective polarizer (20), and a display (10), first mirror (30a), and second mirror (30b) disposed on a same side of the reflective polarizer (20). The reflective polarizer (20) transmits an image emitted by the display (10) after the image is reflected by the first and second mirrors (30a, 30b). A mid-plane defined by intersection points between an optical axis of the system and the display (10), reflective polarizer (20), and second mirror (30b) has one-pass through four-pass regions having respective areas, A1 through A4. The one-pass region includes portions of the emitted image rays (15) that pass at least one time across the one-pass region, the two-pass region includes portions of the image rays (15) that pass at least two times across the two-pass region, the three-pass region includes portions of the image rays (15) that pass at least three times across the three-pass region, and the four-pass region includes portions of the image rays (15) that pass four times across the four-pass region, such that the ratio A4/A3 is between approximately 0.15 and approximately 0.40.
