摘要： A computer device, for instance a palmtop personal organizer, has a dual-orientation display device with both portrait and landscape modes of viewing the display. The keyboard is automatically disabled when the portrait mode is selected by a user. The display has two digitized regions separated by a workspace, which is preferably also digitized to provide input commands to a processor unit when touched. The display further includes indicia, such as icons or symbols shown on the display, which may be selected to activate a computer program, function or command. These icons are slanted and permanently fixed to the display, so they may be readily understood when viewed from either the portrait or landscape modes. A method is also provided of displaying indicia for viewing from two orthogonal directions. The invention further includes a way to use an analog touch-sensitive panel, having opposing resistive layers, to trigger an interrupt line used for returning the palmtop from a sleep mode. In addition, screen image rotation is accomplished by alternately configuring sets of LCD select lines either as column lines or row lines.

摘要翻译： 计算机设备，例如掌上个人管理器，具有双向显示设备，具有观看显示器的纵向和横向模式。 当用户选择肖像模式时，键盘会自动禁用。 显示器具有由工作空间分开的两个数字化区域，其优选地也被数字化以在触摸时向处理器单元提供输入命令。 显示器还包括标记，诸如显示器上显示的图标或符号，其可被选择以激活计算机程序，功能或命令。 这些图标倾斜并永久固定在显示屏上，因此当从纵向或横向模式观看时，它们可以很容易地被理解。 还提供了一种显示从两个正交方向观看的标记的方法。 本发明还包括一种使用具有相对的电阻层的模拟触敏面板来触发用于从睡眠模式返回掌上电脑的中断线的方法。 此外，屏幕图像旋转通过以列线或行线交替地配置LCD选择线组来实现。
