In this event, the touch screen controller will issue an interrupt informing the host the pen is lifted. The host then checks whether there is still data left in FIFO memory to be read. | 2009-05-07 |

| 20090115788 | Mobile computer with auxiliary display on a secondary device - A system and method is disclosed for wirelessly communicating displayable information for display on an auxiliary display device. A primary display device comprising a first display and a first wireless modem generates displayable information. The availability of one or more auxiliary display devices and information is collected to determine which of the auxiliary display devices are supported by the primary display device. The power state of the primary display device is monitored. If it is operating in a full power state, a full auxiliary display output mode is maintained allowing all, or a subset, of the displayable information generated by the first display device to be displayed on supported auxiliary display devices. If it is operating in a low or off power state, a subset auxiliary display output mode is activated and a predetermined subset of the displayable information is displayed on the supported auxiliary display devices. | 2009-05-07 |
| 20090115789 | METHODS, SYSTEMS AND APPARATUS FOR MAXIMUM FRAME SIZE - Apparatus, methods, and systems are disclosed for capturing video frames. The system determines a maximum memory size available for video capture. The system initiates video capture and acquires a frame. The system then analyzes the incoming frame and determines if the frame is larger than the maximum memory size. If the frame is larger than the maximum memory size and if a quality parameter is greater than zero, the quality parameter is lowered. | 2009-05-07 |
| 20090115790 | DISPLAY CONTROL DEVICE AND MOBILE ELECTRONIC APPARATUS - A display control device and technique for controlling displays on a display unit, in which a plurality of display segments are two-dimensionally arranged (e.g. a dot matrix type display unit), is provided. The technique is effectively applicable to a write data latch circuit of a memory for storing display data in the display control device, such as, for example, a liquid crystal display control device, a mobile electronic apparatus, etc. A display drive control technique for controlling a moving picture display mode of a display device is also provided. The display drive control circuit controls a picture display mode of a display device for displaying still pictures and moving pictures to a liquid crystal display device, such as, for example, a dot matrix type display devices, an organic EL display device, etc. | 2009-05-07 |
| 20090115791 | LOADING AN INTERNAL FRAME BUFFER FROM AN EXTERNAL FRAME BUFFER - A system includes internal memory and external memory. A display controller reads a frame from the external memory. At least one of a processor and a graphics chip copies the frame from the external memory to the internal memory while the frame is read from the external memory by the display controller. After the frame is copied to the internal memory, the frame is stored in both the internal memory and the external memory. | 2009-05-07 |
