Abstract

When an electronic product incorporates a display which might be used in low light conditions, it becomes desirable to provide a backlighting means to illuminate the display. One drawback with backlighting is that an extra button is often needed to turn on the device. An approach to eliminating the lamp button includes hury- ing the switching process in a software algorithm, which is c&en confusing and unappealing to the consumer. What is needed is backlighting which is automatically activated by product use.
