Abstract
An electronic device with a display may be provided with an array of pixels each of which includes subpixels formed from organic light-emitting diodes. The electronic device may have support structures such as a head-mountable frame or other head-mountable support structure. Optical structures such as lenses may be provided through which the array of pixels is viewable by a user. The array of pixels and the lenses or other optical structures may be supported by the head-mounted support structure. Light spreading structures may overlap the array of pixels to enhance the fill factor of the pixels. The light spreading structures may be formed from a fiber bundle layer, an array of microlenses, or other optical structures that laterally spread light that has been emitted by the organic light-emitting diodes and thereby enhances the fill factor of the pixels.
