ABSTRACT:
A portable computer having a lid portion pivotally mounted to a body which includes an array of keys. A display section of the lid is aligned, for ease of viewing by an operator, with a subarray of the keys used to display ASCII characters on the display section. For a QWERTY arrangement of keys, a center line of the display section may be aligned, for example, with a line bisecting a row of keys which includes the A through L keys, midway between the F and J keys. The display section and subarray of keys are not aligned with center lines of the lid and body respectively, so that there is more space on one side of the lid adjacent to the display section available for mounting control hardware. The side with more space is used for mounting such hardware as rheostats for adjusting the brightness and contrast of an image on the display section, a back-light arrangement for the display section, an inverter for driving the back-light arrangement, and operation-related indicators.
