Abstract: In some examples, a lighting apparatus includes a light guiding component having a reflective material disposed on at least one surface. The reflective material may be shaped to have desired light reflecting and/or diffusing properties to provide a more uniform light distribution, such as for lighting an electronic display or other surface. In some cases, the reflective material may be a white tape having a reflective light-diffusing surface. The light reflecting material may be cut or otherwise shaped to provide the desired light reflecting and/or diffusing properties. As one example, the amount of the reflective material located over a central axis of light emitted by a light source may be greater than the amount reflective material located between light sources. This disclosure also describes techniques for assembling electronic devices in a component stack to provide enhanced display lighting uniformity.

CPC classification number: G02B6/0073 , G02B6/0065
Abstract: Technologies are described herein for photobleaching a display. A display may be photobleached by exposing the display to light emitted by an external lamp and/or may be photobleached using one or more display lights of the electronic device during a burn-in period. In some examples, the light emitted by the lamp is filtered to remove wavelengths below a certain wavelength. The light that is received by the display from the lamp may include wavelengths between about 310 nm and 700 nm. These wavelengths correspond to visible light and near-visible light. The display may be exposed to the light for some duration or until some dose of light is received by the display. In other configurations, a burn-in period is performed for about eighteen hours.

Abstract: Systems, methods, and devices are disclosed for front-lit displays having uniform brightness. In one embodiment, an example display may include an electrophoretic display, a light guide configured to direct light from one or more light emitting diodes, and a cover lens assembly. The cover lens assembly may include a cover glass layer, an anti-glare film coupled to the cover glass layer, and a hot melt adhesive disposed about lateral edge surfaces of the cover glass layer and the anti-glare film, such that the hot melt adhesive forms a perimeter of the cover lens assembly.

Abstract: A multifunctional device layer may include a lightguide substrate having an optically patterned surface and an opposing non-patterned surface. The non-patterned surface of the lightguide substrate is coated with a first material having a first refractive index and the patterned surface is coated with a second material having a second refractive index. The first refractive index may be lower than the second refractive index and each may be lower than a refractive index of the lightguide substrate. A touch sensor may be formed on the coated non-patterned surface of the lightguide substrate, the coated patterned surface, or on an interstitial layer deposited on the coated non-patterned surface or the coated patterned surface. An anti-glare/anti-reflective coating potentially having ultraviolet (UV) absorption properties may be applied to the touch sensor.

Abstract: An electronic device with a flexible display subassembly is provided. The display stack may use two layers of adhesives having different elastic properties to improve mechanical impact resistance, with a first adhesive layer made of a viscoelastic material and a second adhesive layer having a low modulus of elasticity. The display stack may also include a hot melt protective sheet (HMPS) covering the display subassembly. The HMPS may be wrapped around the two side edges of a rigid substrate to attach directly to the substrate, thereby aiding in the adhesion of the display stack to the substrate. The display stack may also includes a patterned back protective sheet in which the protective backing layer is removed along the curved portions of the display stack.
