    Abstract: Three-dimensional display systems may include polarized displays that polarize light emitted from a first set of areas of the display with a first polarization for a first eye of the viewer and that polarizes light emitted from a second set of areas of the display with a second polarization for a second eye of the viewer. This may result in dark areas being perceived by a viewer when viewed through polarized 3D glasses. Systems and technologies according to this disclosure may include 3D glasses that have a lenses configured to redirect a portion of incoming light in a first axis to at least partially illuminate the dark areas.

    Abstract: Systems, methods, and computer-readable media are disclosed for high contrast frontlight structures for reflective displays and related devices. In one embodiment, an example display structure may include a diode, a reflective display, and a light guide coupled to the reflective display and configured to direct light from the diode, the light guide. The light guide may include a first layer having a first refractive index value, a second layer having a second refractive index value, a third layer having the first refractive index value, and a fourth layer having the second refractive index value, where the second refractive index value is greater than the first refractive index value.

    Abstract: A thin border display for an electronic device may comprise an optical assembly that includes a support frame and an electrophoretic display (EPD) structure attached to the support frame in a manner that allows for the display of the electronic device to exhibit a “thin border” or “borderless” look at a periphery of the electronic device. A portion of the EPD structure may at least partly curve around a curved portion of the support frame, the curved portion of the support frame being near the periphery of the support frame. In some embodiments, an electrode may be disposed at a periphery of the display to drive the margin of the display for achieving a thin border/borderless appearance. The EPD structure may include a backplane substrate that is either rigid or flexible.

    Abstract translation: 用于电子设备的薄边框显示器可以包括光学组件，其包括以允许电子设备的显示呈现“薄边框”的方式附接到支撑框架的支撑框架和电泳显示器（EPD）结构， 或“无边界”看电子设备的周边。 EPD结构的一部分可以至少部分地围绕支撑框架的弯曲部分弯曲，支撑框架的弯曲部分靠近支撑框架的周边。 在一些实施例中，电极可以设置在显示器的周边以驱动显示器的边缘以实现薄边框/无边界外观。 EPD结构可以包括刚性或柔性的背板基板。

    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.
