Abstract
A preferred embodiment relates to controlling the amount of backlight in an electronic display to account for the temperature in the backlight cavity. Another embodiment relates to a system for controlling the amount of backlight based on both the temperature in the backlight cavity and the amount of ambient light. The embodiments are especially useful in electronic displays which are subjected to cold or warm temperatures and displays which are placed in very bright environments. Exemplary embodiments allow the display to remain visible, while avoiding possible damage due to high levels of heat or cold.
