US Patent 9829710 Display with stacked emission and control logic layers

The disclosure relates generally to a display panel, which in at least some situations includes multiple separate stacked layers or components that are combined together, such as to have one emission layer component with numerous pixels that emit light, and to have at least one control logic layer component that includes integrated circuits or other logic to control the emission of light by the pixels in the emission layer. The different layers may be separate silicon chips or wafers that are connected in a stacked structure via a flip chip technique, with the emission layer using AMOLED or other OLED pixels. The display panels may be designed and/or configured for use in head mounted displays (e.g., with a fully immersive virtual reality system). The disclosure also relates generally to techniques for manufacturing, testing and/or otherwise using such a display panel in various manners.
