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.
