Description

FIELD

Certain embodiments of the disclosure relate to character displays. More specifically, certain embodiments of the disclosure relate to a method and system for direct character display control.

BACKGROUND

A display device may display characters such as digits (digital numbers) and/or letters. A display device may be, for example, an electronic clock, a mobile phone, a smart phone, a tablet or other type of similar device. Digital displays, such as those used by electronic clock devices, often use indirect methods for modifying display data. For example, an alarm clock device may use a single button to cycle through hours and another button to cycle through minutes. Another example is the use of a knob control to update the displayed digits. In such an instance, however, the control may still be very slow.

Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with the present disclosure as set forth in the remainder of the present application with reference to the drawings.
