Display Area Specifications

The Web browser renders text and icon content in the Application Area, between the top of the top Application Line and the bottom of the bottom Application Line. Image content may extend across Application Lines. WBMP or JPEG images can appear in the softkey label area. Figure 14 depicts how the Web browser renders content. Figure 15 shows the height and width of the Application Area.

Displays on 9xxx telephones are framed by a 1-pixel-wide black border, making the usable area inside 2 pixels smaller in the horizontal (H) and vertical (V) dimensions, as specified in Figure 15:

Figure 16 is a schematic of the usable area divided by function. Not all telephone models are required to support all of the functional areas:

Figure 16:  Display Area Breakdown

The Top Area is subdivided vertically into a Top Line, a Title Line, and a Prompt Line. Each top area line extends across the entire width of the usable area.

The Top Line of four grayscale phones displays as black text on a light gray background. The Title Line of four grayscale phones displays white text on a black background. The Prompt Line of four grayscale phones displays black text on a white background.

The Application Area displays application content, softkey labels, and a Scroll Bar, if needed. The entire Application Area background for the four grayscale phones is always a single color, which is dark gray by default.

Text and icon content always display on Application Lines. Application lines are 23-pixel-high horizontal areas, to align with any Line Buttons or LEDs located to the right of the display. There is a 5 pixel vertical gap of above the first Application Line and below the last Application Line for the 9620 and 9630. There is also a relatively large horizontal gap between the left side of the Application Lines and the left-side border pixel, where the Scroll Bar can be displayed. A smaller horizontal gap exists between the right side of the Application Lines and the right-side border pixel. Text and icons may not be displayed in gap areas around the Application Lines, although images, for example, in the Web browser, may extend across Application Lines. Text displayed directly on the Application Area background is black unless specified otherwise by the Web application.

A Scroll Bar displays vertically to the left of the Application Lines only if the display content does not fit the viewable area. When displayed, the Scroll Bar extends from the top Application Line to the bottom Application Line, inclusive, with the same gaps above and below. Small gaps remain on either side to separate the Scroll Bar from the left-side border pixel and from any other content displayed in the Application Area.

Figure 17 specifies the use of pixels horizontally across the usable display area containing Application Lines.

Figure 17: 

A single row of Softkey Labels is displayed below the Application Lines and the Scroll Bar (if present). Softkey Labels are 20 pixels high, and there is a gap below the labels to separate them from the bottom border pixel. By default, Softkey Labels are black with white text.

Figure 18 specifies the use of pixels horizontally across the usable display area that contains Softkey Labels.

Figure 19 specifies the vertical use of pixels in the Application Area and Scroll Bar.

Softkey Labels are positioned above the associated softkeys buttons.

The background of a given area refers to all pixels in that area that are not being used to present text glyphs, icons, or other objects.

The Title Line is the second line in the Top Area. The Title Line is comprised of the current application Title, a subtitle if the application provides one, and choice or Web paging indicators. The Title is left justified on the Title Line. The Title is followed by a minimum of two spaces, followed by the subtitle. The subtitle is centered in the remaining area to the right of the title and to the left of the choice indicators. If an icon such as the Page History Indicator exists, that icon is right justified.

If the Title Line text exceeds the pixels allocated for that line, any characters that follow the last whole character that fits are truncated.

The Prompt Line is the 3rd line in the Top Area. The current application uses the Prompt Line to provide context-specific prompts, hints, explanations, help, or similar information. Application specific help messages are managed by each application. All Prompt Line text is left justified.

If text on the Prompt Line exceeds the pixels allocated for that line, any characters that follow the last whole character are truncated.

All browser text is in the Prima Sans Bold font, 14 pixel.

On average, the character counts for display lines are:

• Top line- Lower case, 312 pixels = 36 characters
• Title line - Mixed case, 312 pixels = 35 characters
• Prompt line - Upper case, 312 pixels = 30 characters
• Each Application line - Numbers, 292 pixels = 30 digits/characters
• Softkeys -as follows:
• 8 characters with 1 uppercase and 7 lowercase characters, or
• 7 characters with 2 uppercase characters, 5 lowercase characters, and 1 space, or
• 7 characters with 1 uppercase character, 6 lowercase characters, or
• 8 characters with 7 alpha characters, 1 digit, and 1 space.

Display line character counts are based on:

• approximately 8.5 pixels per character for lowercase,
• approximately 9 pixels per character for mixed case,
• approximately 10.4 pixels per character for uppercase,
• Approximately 9.6 characters per digit for numeric, and
• 5 pixels per space for spaces.
