Abstract
An electronically controlled appliance capable of automatically adjusting a contrast level of a data display module is disclosed. The device includes an appliance, an intelligent control electrically connected to the appliance and adapted for controlling the appliance, a data display module capable of contrast adjustment and electrically connected to the intelligent control, a data storage medium electrically connected to the intelligent control storing software instructions for monitoring the amount of time the appliance is in an active state and instructions for compensating for the temperature change associated with the amount of time by adjusting the contrast level of the data display module.
Claims7
An electronically controlled cooking appliance comprising:
- an intelligent control electrically connected to the cooking appliance and adapted for controlling the cooking appliance;
- a data display module capable of contrast adjustment electrically connected to the intelligent control;
- and
- a data storage medium electrically connected to the intelligent control for storing software instructions for monitoring the amount of time the cooking appliance is in an active state and instructions for compensating for the temperature change associated with the amount of time and adjusting accordingly the contrast level of the data display module.
A method for automatically adjusting a contrast level of a data display module in a cooking appliance comprising:
- determining whether the cooking appliance is in an active state and if so, an amount of time the cooking appliance has been in the active state;
- estimating the temperature change in the data display module to be compensated for based upon the amount of time the cooking appliance has been in the active state;
- and
- adjusting the contrast level of the data display module to compensate for the temperature change in the data display module.
The method of claim % wherein the step of adjusting the contrast level includes compensating for user adjustment of the contrast level.
