摘要： A light assembly can have an array of light sources forming rows and columns, where the array comprises a plurality of chips, and each chip comprises a subarray of light sources forming the rows and columns. A boundary between chips in the array can be configured to extend diagonally across rows and columns of the array such that, for each column across which the boundary extends, the first row of the plurality rows may not have a light source disposed in the respective column, but a second row of the plurality of rows has a light source disposed in the respective column.

摘要： Techniques related to eye tracking using reverse-biased light-emitting diode (LED) devices are disclosed. In some embodiments, a viewing apparatus comprises a reverse-biased LED device that is positioned within a field-of-view of an eye. The reverse-biased LED device receives light reflected from the eye and generates signal based on the received light. The generated signal is used to determine a position of the eye.
