Abstract
Systems, methods, and computer-readable media are disclosed for dual-color frontlit displays with near uniform color mixing. In one embodiment, an example device may include a light emitting diode (LED) array that includes a first LED that emits light having a first color and a second LED that emits light having a second color, and a light guide that includes a surface having a first portion adjacent to the first LED and a second portion adjacent to the second LED. The first portion may include a first number of binary element surface features formed on the surface, and the second portion may include a second number of binary element surface features formed on the surface. The first number of binary element surface features may be substantially parallel to a first direction of light emitted from the first LED, and the second number of binary element surface features may be substantially parallel to a second direction of light emitted from the second LED, wherein the second direction is substantially perpendicular to the first direction.
