Electronic device comprising a gamma correction unit, a process for using the electronic device, and a data processing system readable medium

A process for using an electronic device wherein the process comprises:

• operating a first array of radiation emitting components corresponding to a first gamma correction unit having a first and a second gamma function;
• operating the first array during a first time period, wherein the first gamma function for the first gamma correction unit is used during the first time period;
• operating a second array of radiation emitting components corresponding to a second gamma correction unit having a third and a fourth gamma function;
• operating the second array during the first time period, wherein the third gamma function for the second gamma correction unit is used during the first time period;
• wherein the first and second gamma correction units comprise a first tap, a second tap, a fifth tap and a sixth tap wherein:
• the first tap provides a first lowest value for a first output value for the first gamma correction unit;
• the second tap provides a first highest value for the first output value for the first gamma correction unit;
• the fifth tap provides a second lowest value for a second output value for the second gamma correction unit;
• the sixth tap provides a second highest value for a second output value for the second gamma correction unit;
• and
• the first gamma correction unit further comprises a third tap that provides a first intermediate value for the first output value for the first gamma correction unit, wherein:
• the first intermediate value is between the first lowest value and the first highest value;
• and
• the third tap is configured to allow the first intermediate value to be changed after the electronic device has been fabricated;
• changing the first gamma function to the second gamma function that is different from the first gamma function;
• changing the third gamma function to the fourth gamma function that is different from the third gamma function;
• operating the first and second arrays during a second time period, wherein the second gamma function for the first gamma correction unit is used during the second time period and the third gamma function for the second gamma correction unit is used during the second time period.

A data processing system readable medium having code for using an electronic device comprising an army of radiation-emitting components and a first and a second gamma correction unit, wherein the first and second gamma correction units comprise a first tap, a second tap, a fifth tap and a sixth tap wherein:

• the first tap provides a first lowest value for a first output value for the first gamma correction unit;
• the second tap provides a first highest value for the first output value for the first gamma correction unit;
• the fifth tap provides a second lowest value for a second output value for the second gamma correction unit;
• the sixth tap provides a second highest value for a second output value for the second gamma correction unit;
• and
• the first gamma correction unit further comprises a third tap that provides a first intermediate value for the first output value for the first gamma correction unit, wherein:
• the first intermediate value is between the first lowest value and the first highest value;
• and
• the third tap is configured to allow the first intermediate value to be changed after the electronic device has been fabricated;
• and, wherein the code is embodied within the data processing system readable medium, the code comprising:
• an instruction for operating the array during a first time period, wherein a first gamma function for the first gamma correction unit is used during the first time period;
• an instruction for changing the first gamma function to a second gamma function that is different from the first gamma function;
• and
• an instruction for operating the array during a second time period, wherein the second gamma function for the first gamma correction unit is used during the second time period.
