Problems solved by technology

Alphanumeric products are also known which are equipped with means by which the speed of message movement can be pre-selected by the user; however there is the disadvantage that the speed of movement in such products remains unresponsive to the content of the message

Embodiment Construction

[0015] figure 1 Display device 10 is shown comprised of display 12 electronically coupled to processor 22 , counter 14 , random access memory (RAM) 16 , read only memory (ROM) 18 , and oscillator 20 . Display 12 is adapted to display alphanumeric characters, each alphanumeric character preferably being formed from a preselected element of a matrix having C columns and R rows of elements. The display preferably contains W (W greater than C) column elements and at least R rows. The display 12 is preferably a liquid crystal display (LCD) element, but could also be a light emitting diode (LED) element. Such display devices are well known to those skilled in the art, so details will not be described here. The display is preferably a single line display capable of displaying approximately 12 to 20 alphanumeric characters for use in portable communication devices such as pagers. The number of characters that can be displayed on the visible portion of the display depends on the wid...

Abstract

A visual display device (10) coupled to a processor (22), a memory (16, 18) and a counter (14) produces procession of displayed alphanumeric characters until a consecutive sequence of at least four muneric or punctuation characters is displayed, at which time the procession stops prior to any character of the at least four consecutive numeric or punctuation characters processes off a viewable portion of a visual display (12). The procession remains stopped until a user of the visual display device intervenes to cause resumption of procession. The visual display device gradually slows the rate of procession when words of at least five consecutive alphanumeric characters are displayed, and gradually increases the rate of procession when words of at least five consecutive alphanumeric characters are no longer displayed. A selective call receiver (11) includes a receiver (23) and the visual display device (10) to display received wireless messages.

Description

technical field [0001] The present application relates generally to displays on portable communication devices, and in particular to controlling the movement of a sequence of alphanumeric characters on a display device. Background technique [0002] Portable communication devices, such as pagers, have relatively small displays in an attempt to keep the size of the portable device small. Typically, a pager can receive a message containing a much greater number of alphanumeric characters than the maximum number of alphanumeric characters that can be simultaneously displayed on a display device. As a result, only a portion of a long message can be displayed simultaneously, and the long message must then be moved along the display, or scrolled, for example, from right to left. Movement of textual material across relatively small display devices creates several disadvantages, one of which is that parts of the text become invisible after a short time on display; moreover, these p...
