First Claim
1. A computer, comprising:
- a display module disposed within a display housing;
a central processing unit operably connected to the display module through a data bus and disposed within a computer housing separate from the display housing;
a temperature sensor positioned in the display module and configured to detect a temperature of at least a portion of the display module; and
an electronic control device communicatively coupled to the temperature sensor through the data bus and operably coupled to the display module, wherein the electronic control device is configured to adjust a brightness of the display module responsive to the detected temperature to reduce heat within the display module when the detected temperature exceeds a predetermined value;
wherein the electronic control device is configured to reduce heat within the display module by disabling one or more heat producing components within the display module.

Abstract
A temperature sensing apparatus (10) and associated method (60) wherein a temperature sensor (22) or a plurality of temperature sensors (22) is placed in or in near proximity to a liquid crystal display module (12) of a computer system (11, 11a, 11b). The temperature sensor(s) (22) are placed on, or in near proximity to the liquid crystal display module (12) at positions determined according to the requirements of a particular application. Temperature of the liquid crystal display module (12) is communicated digitally to an associated computer (14) by, for example, a bus such as an inter-integrated circuit interface bus (26). When the temperature exceeds a predetermined limit, remedial action, such as increasing fan speed, reducing speed and or power consumption of other components, or the like, is taken to reduce the temperature.
