  • Patent number: 7405712
    Abstract: Aspects of the invention can provide a method for driving an electro-optical device, an electro-optical device and electronic equipment that can solve the insufficient supply of the data current and current fluctuation. In the driving method, a data current can be applied to a plurality of pixels provided to a display panel unit with same value through the data line regardless of grayscale data. Upon supply of the data current, in the pixel, a transistor selected in reproduction can be turned on such that a drive current corresponding to the data current output from a driving transistor is supplied to an organic EL element, thereby emitting light. A light-off signal can be supplied to the pixel at predetermined timing such that the organic EL element emits light only in the light-emitting period computed based on the grayscale data.

  • Patent number: 7375714
    Abstract: Aspects of the invention are intended to stabilize the initial state of an active matrix so as to reduce unnecessary power consumption and stabilize the operation. The driving device can include a selection device that is coupled to any of a plurality of row direction lines and any of a plurality of column direction lines, and by which a selected state and a non-selected state of the row direction lines or the column direction lines are switched to each other. The driving device can also include a device that switches to the non-selected state that switches the selection device coupled to the row direction lines or the selection device coupled to the column direction lines to a non-selected state. Selection by the selection device can be implemented after the selection device is switched to a non-selected state by the device that switches to the non-selected state.

  • Patent number: 7341894
    Abstract: In a semiconductor device made by forming functional elements on a first substrate, transferring the element chip onto a second substrate, and connecting first pads on the element chip to second pads on the second substrate, the area or the width of the first is increased. The first pads can be securely connected to the second pads even when misalignment occurs during the separating and transferring processes. Only the first pads are formed on a surface of the element chip at the second-substrate-side. The functional elements are formed to be farther from the second substrate than the first pads. Alternatively, only the first pads are formed on a surface of the element chip remote from the second substrate, and the functional elements are formed to be closer to the second substrate than the first pads. Alternatively, the first pads are formed on both the surface of the element chip at the second-substrate-side and the surface of the element chip remote from the second substrate.

  • Publication number: 20080005388
    Abstract: A method that enables an image forming device of efficient memory sharing between processes and a kernel in a simple multiple-process-configuration. The image forming device has a real address space including a DMA buffer area and a shared memory area, a virtual address spaces, and job page assurance (JPA) programs. The virtual address spaces of the executing processes are mapped onto the real address space. The DMA buffer area can be accessed by the kernel. The shared memory area stores a job list and a job management list. The processes in the virtual address spaces include identical JPA libraries. Each of the JPA libraries requests the kernel to allocate of one page non-compressed data memory size for the job in the DMA buffer area, and upon completion of the job output, requests the kernel to release the allocated area and alters the contents in the job management list accordingly.

  • Publication number: 20070263252
    Abstract: A method that enables a multiple-port print device to perform efficient job management for each job even if the multiple-port print device is provided with parallel-processing-enabled multiple interfaces. The multiple-port print device includes a job boundary detection unit, a spool buffer, and a job management unit. By reading print job data stored in the buffer memory units from the multiple communication interfaces, and detecting the job start and end marks added to the print job data, the print job data is identified by each job boundary. The job management unit stores the print job data identified by the job boundary into the spool buffer as a spool file to spool-process the data between the spool buffer and the image processing unit.
