In a personal communications device having a touch sensitive display screen, text may be marked by a user to be used with different applications. In particular, to begin marking, a user has to maintain his touch at a location on the screen for a short predetermined period of time until the system detects that the position is held over the same character for a delayed period, at which time the system beeps to provide an indication that there has been a change of operation mode. The marking mode continues in operation until the user removes his contact from the touch screen. Thus, text over which the contact point passes after the initiation of the marking mode is marked, until the user removes his contact point from the touch screen. A second beep is sounded to alert the user of the termination of the marking mode, and the appearance of a menu of operations on the screen. The menu of operations echoes the marked text for user confirmation. The marked text may be used by the user in a number of applications, among which include a calling application whereby the marked text is used to place a call.

A display device having a display matrix including a pixel border of width x and located around the edge locations of the matrix for improved viewability. The pixels of the border are “dummy pixels” each containing a red, a green and a blue subpixel. Each subpixel has a color filter and is manufactured with a “dummy” transistor which operates to fix open the subpixels thereby allowing a predetermined amount of “white” color brightness through the dummy pixels. The pixel border is useful for increasing viewability of characters that are displayed along the edge of the LCD matrix area in which images are generated from a frame buffer memory.
摘要:
A flip-style user interface for controlling a display on a device such as a computer system, and a method thereof. Layers of flexible material are coupled along one edge in a stack that is coupled to the computer system. A user flips the layers (e.g., leaves) in a manner similar to the way pages in a book are flipped. The separation and/or bending of the leaves caused by the flipping is translated into changes in the display. For example, a different page in a document, calendar, or address book can be displayed as the user moves (separates or bends) the leaves of the user interface. Separation of the leaves can be detected by conducting pads positioned on the top and bottom surfaces of each leaf, such that a pad on the surface of one leaf is in electrical contact with a corresponding pad on the facing surface of the adjacent leaf. The pads are separated when the leaves are separated, breaking the electrical connection and allowing the separation to be detected. Bending of the leaves can be detected using a strain gauge, an accelerometer, an optical sensor, or other such instruments. The rate at which the leaves are moved, the order in which they are moved (e.g., front to back, or vice versa), and the amount of deflection imparted to the leaves can be used to control various aspects of the display.

A portable computer system (e.g., a palmtop or hand-held computer system) is implemented with an interface module containing circuitry needed to connect with and operate a device such as a display device. The interface module is coupled to the display device. Additionally, the interface module may be coupled to a printed circuit (PC) board of the portable computer system. As such, PC board can thus be designed and manufactured independently of the display device. Furthermore, design variations in the display device can be independently accommodated in the interface module. Thus, the combination of the interface module, the device, and/or the PC board can be universally implemented in different designs of portable computer systems, reducing development time and manufacturing costs.
