Abstract

An electronic device includes at least one gamma correction unit including a first gamma correction unit. In one embodiment, the first gamma correction unit includes at least one tap that is configured to allow the gamma function for the first gamma correction unit to be changed after the electronic device has been fabricated. In another embodiment, a process for using the electronic device operating the array during a first time period using a first gamma function for the first gamma correction unit. The process also includes changing the first gamma function to a second gamma function. The process further includes operating the array during a second time period using the second gamma function for the first gamma correction unit. A data processing system readable medium has code that includes instructions for carrying out the process.
