Fabric enclosure backlighting techniques are described. In one or more implementations, one or more translucent portions are formed within a plurality of layers of a fabric enclosure assembly. In one approach, regions within one or multiple layers are laser etched to form the translucent portions within the fabric enclosure assembly. A light source is then arranged to selectively transmit light through the layers via the translucent portions to provide backlight for one or more elements integrated with fabric enclosure assembly. The one or more elements may include representations of input keys and/or graphics associated with the fabric enclosure assembly. The backlight may be used to view the one or more elements in low light and/or provide backlight effects such as borders, side lighting, labels, and so forth.

1. An apparatus comprising: a light source;a flexible outer cover of the apparatus comprising an assembly having flexible layers including at least an outer skin, a backer layer, and one or more middle layers disposed between the outer skin and the backer layer;a sensor substrate beneath the flexible outer cover having one or more conductors disposed thereon;one or more flexible translucent portions formed in the flexible layers to enable transmission of light from the light source through the flexible layers to provide backlight for elements integrated with the assembly, a flexibility of the flexible layers is reduced for one or more locations relative to the flexibility of the flexible layers at other locations, andthe other locations having greater flexibility cause a stronger signal to be generated via the one or more conductors when contact is created at the other locations having the greater flexibility than a signal generated via the one or more conductors when contact is created at the one or more locations having the reduced flexibility; anda pressure sensitive sensor stack configured to be contacted responsive to pressure applied at locations of one or more of the elements integrated with the assembly that represent underlying input keys to initiate communication of corresponding inputs to a computing device that is communicatively coupled to the apparatus, the pressure sensitive stack comprising force sensitive ink having a conductivity that varies directly in relation to an amount of the pressure applied. 2. The apparatus as described in claim 1, further comprising a connection portion configured to connect the apparatus as an accessory device to the computing device. 3. The apparatus as described in claim 1, wherein the one or more flexible translucent portions are formed by laser etching into one or more of the flexible layers. 4. The apparatus as described in claim 1, wherein the one or more flexible translucent portions include at least one region etched into a top surface of the outer skin that is exposed in the assembly. 5. The apparatus as described in claim 1, wherein the one or more flexible translucent portions include regions formed in multiple different layers of the flexible layers. 6. The apparatus as described in claim 1, wherein the one or more flexible translucent portions include at least one region etched into one of the middle layers. 7.

An apparatus comprising: a light source;a flexible outer cover of the apparatus comprising an assembly having flexible layers including at least an outer skin, a backer layer, and one or more middle layers disposed between the outer skin and the backer layer;a sensor substrate beneath the flexible outer cover having one or more conductors disposed thereon;one or more flexible translucent portions formed in the flexible layers to enable transmission of light from the light source through the flexible layers to provide backlight for elements integrated with the assembly, a flexibility of the flexible layers is reduced for one or more locations relative to the flexibility of the flexible layers at other locations, and the other locations having greater flexibility cause a stronger signal to be generated via the one or more conductors when contact is created at the other locations having the greater flexibility than a signal generated via the one or more conductors when contact is created at the one or more locations having the reduced flexibility; anda pressure sensitive sensor stack configured to be contacted responsive to pressure applied at locations of one or more of the elements integrated with the assembly that represent underlying input keys to initiate communication of corresponding inputs to a computing device that is communicatively coupled to the apparatus, the pressure sensitive stack comprising force sensitive ink having a resistance that decreases directly in relation to an amount of the pressure applied. 16. The apparatus as described in claim 15, further comprising a connection portion configured to connect the apparatus as an accessory device to the computing device. 17. The apparatus as described in claim 15, wherein the one or more flexible translucent portions are formed by laser etching into one or more of the flexible layers. 18. The apparatus as described in claim 15, wherein the one or more flexible translucent portions include at least one region etched into a top surface of the outer skin that is exposed in the assembly. 19. The apparatus as described in claim 15, wherein the one or more flexible translucent portions include regions formed in multiple different layers of the flexible layers. 20. The apparatus as described in claim 15, wherein the one or more flexible translucent portions include at least one region etched into one of the middle layers.
