Abstract: A pixel cell includes a second photodiode laterally surrounding a first photodiode in semiconductor material. The first and second photodiodes are adapted to photogenerate image charge in response to incident light. A floating diffusion is disposed in the semiconductor material proximate to an outer perimeter of the second photodiode. A first transfer gate is disposed proximate to the semiconductor material over a first channel region between the first and second photodiodes. The first transfer gate is coupled to transfer the image charge from the first photodiode to the second photodiode. A second transfer gate is disposed proximate to the semiconductor material over a second channel region between the second photodiode and the floating diffusion. The second transfer gate is coupled to transfer the image charge from the second photodiode to the floating diffusion.

Abstract: A novel head mounted display includes a display/image sensor. In a particular embodiment the display/image sensor is formed on a single silicon die, which includes display pixels and light sensor pixels. The display pixels and light sensor pixels are each arranged in rows and columns, and the arrays of light sensor pixels and display pixels are interlaced. The center of each light sensor pixel is located between adjacent rows and adjacent columns of display pixels.
