Abstract
Provided are a system and method for reducing failures due to hinge memory. The method, in one embodiment, includes providing a torsional element having an amount of hinge memory, wherein the hinge memory is at least partially created using an average operational temperature. The method, in this embodiment, further includes subjecting the torsional element having the hinge memory to a temperature equal to or greater than the average operational temperature while the torsional element is in a parked state for an amount of time to reduce the amount of the hinge memory.
Claims22
A method for reducing hinge memory in a device, comprising:
- providing a torsional element having an amount of hinge memory, wherein the hinge memory is at least partially created using an average operational temperature;
- and
- subjecting the torsional element having the hinge memory to a temperature equal to or greater than the average operational temperature while the torsional element is in a parked state for an amount of time to reduce the amount of the hinge memory.
A method for operating a digital micromirror device based display system, comprising:
- initiating a power up cycle of a digital micromirror device including an array of micromirrors;
- moving states of individual ones of the array of micromirrors between ON and OFF in a presence of a light source to display an image, wherein the moving occurs over an average operational temperature and at least partially creates an amount of hinge memory in the individual ones of the array of micromirrors;
- initiating a power down cycle of the digital micromirror device including the array of micromirrors;
- and
- subjecting the array of micromirrors having the amount of hinge memory to a temperature equal to or greater than the average operational temperature while the individual ones of the array of micromirrors are in a parked state for an amount of time to reduce the amount of hinge memory.
A display system, comprising:
- a light source;
- an array of micromirrors optically coupled to the light source;
- control electronics configured to receive image data, and control the light source and a modulation of the array based upon the image data to produce one or more images on a display plane;
- and
- a controller associated with the array, the controller configured to maintain a temperature of the array at or increase a temperature of the array above an average operational temperature thereof while individual ones of the array of micromirrors are in a parked state for an amount of time to reduce an amount of hinge memory in the individual ones.
