US 11,143,806 B1 · Electronic devices having pixels with elevated fill factors

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.

Dependent claims

An electronic device with a display configured to display images viewable by a user, comprising:

a head-mounted support structure;
an array of pixels supported by the support structure, wherein the array of pixels is configured to produce light associated with the images;
a fiber bundle layer that overlaps the array of pixels;
and
an optical system supported by the head-mounted support structure through which the images are viewable, wherein the array of pixels is formed from a layer of thin-film circuitry containing thin-film transistors, a layer of patterned anodes on the layer of thin-film circuitry, organic emissive material on the anodes, a cathode layer, and an overcoat layer and wherein the overcoat layer is interposed between the fiber bundle layer and the cathode layer.
