Abstract
The invention relates to methods and apparatus for forming images on a display utilizing a control matrix to control the movement of MEMs-based light modulators.
Claims40
A display apparatus comprising:
- a transparent substrate,
- an array of pixels including a plurality of MEMS light modulators each corresponding to a pixel in the array, and
- a control matrix formed on the transparent substrate and having, for each pixel in the array, a set of switches connecting an energy source to a MEMS light modulator of the respective pixel, the set of switches comprising a first switch and a second switch directly connected in series.
The display apparatus of claim.4, comprising a cascode interconnect for supplying the second voltage to the gate of the second transistor.
A display apparatus comprising:
- a transparent substrate,
- an array of pixels including a plurality of MEMS light modulators each corresponding to a pixel in the array, and
- a control matrix formed on the transparent substrate and having, for each pixel in the array, a first switch and a second switch directly connected in series and through which current flows from a MEMS light modulator of the respective pixel to a current drain interconnect.
A display apparatus, comprising:
- a transparent substrate,
- an array of pixels including a plurality of light modulators each corresponding to a pixel in the array, and
- a control matrix formed on the transparent substrate and having, for each pixel in the array,
- a charging cascode connecting an energy source to a light modulator of the respective pixel, and
- a discharging cascode through which current flows from the light modulator of the respective pixel to a current drain interconnect, wherein the charging and discharging cascodes are connected to a common interconnect.
