    Abstract: A pixel circuit, an organic electroluminescent display panel and a display device. The pixel circuit comprises: a drive transistor, a drive control module, at least two split light emitting control modules and light emitting devices connected with output terminals of the split light emitting control modules in one-to-one correspondence respectively. Since the plurality of split light emitting control modules can split the driving total current signal outputted by the drive transistor based on the corresponding split control signal, the driving split current signal outputted to the corresponding light emitting device can be less than the driving total current signal. Thus, the driving current of the light emitting device under the same brightness can be reduced, thereby being capable of realizing adjustment of various gray scale display of the high current efficiency light emitting device.

  • Patent number: 9697795
    Abstract: The present disclosure discloses a video processing device and method, the device comprising a dual matrix selecting module and a dual channel color data processing module. Due to the use of the dual channel color data processing module, two groups, i.e. an odd group and an even group, of pixel data can be processed simultaneously within one clock period. Since two dithering matrices are used when two adjacent frames of images are displayed, the structure is simple, and the processing speed is high. The present disclosure uses the algorithm period of two frame cycle for dithering in time and uses the dithering matrix of 2*2 for dithering in space, so as to achieve the effect of dithering 8 bit video data using 6 bit display data. Moreover, due to the use of two dithering matrices, the display performance of the display can be improved, two groups, i.e. an odd group and an even group, of pixel data are processed simultaneously within one clock, which reduces the working frequency of the circuit.

  • Patent number: 9697801
    Abstract: The present invention relates to a digital display plotter for plotting images on a digital display device 18. A cursive imagery generator 12 generates imagery inputs at a plurality of respective update phases during a refresh period of the display device. A control 20 for the display device activates selected pixels of the digital display device in response to respective said imagery inputs, activation being controlled subsequent to each update phase during a refresh period. An input store 14, 16 associates each cursively generated imagery input with an update phase that the imagery input was generated during a refresh period. The control 20 is responsive to the input store and configured to deactivate the selected pixels activated in response to each imagery input dependent on the associated update phase of each imagery input.

  • Patent number: 9697802
    Abstract: A display control circuit of a display performs generation of overdrive processed data and detection of a proper direction of overdriving from current frame uncompressed compressed data obtained by performing compression processing and uncompression processing on compressed data corresponding to image data of a current frame, and previous frame uncompressed compressed data obtained by performing the compression processing and the uncompression processing on image data of a previous frame, and generates post-correction overdrive processed data by correcting the overdrive processed data according to the detected proper direction. The display control circuit transmits post-correction compressed data obtained by compressing the post-correction overdrive processed data to a driver as transfer compressed data.

  • Patent number: 9697804
    Abstract: A system and computer program product for displaying data in a graphical overlay. The system overlays a first lens, including a first dataset, on a first region of the graphical overlay while a second lens, including a second dataset, overlaps the first lens. The first and second datasets are simultaneously displayed, and a correlation between the datasets is determined. Separation of the first and second lenses preserves a circumscribed region within each lens. The first dataset corresponds to first orientation position of the first lens. Rotation of the first lens to a second orientation position reconfigures the first dataset to provide a modified first dataset which corresponds to the second position. A rotational position may also be associated with points in time, a first position corresponding to a first point in time and the first dataset representing the first dataset at the first point in time.

  • Patent number: 9697807
    Abstract: An instant access guitar system allowing easy access to cavities in the body portion of the electric guitar. The cavities are covered by plates, a pick guard, flexible laminates or other suitable cover materials. The covers are held in place by (1) cut-outs in the guitar body and (2) magnets that magnetically attach to magnetic material mounted in the guitar body. The appearance of the guitar may be changed by changing the pick guard and the decorative laminate on the headstock. The sound of the guitar may be changed by having unique pickups and wiring releases pre-built in multiple configurations on multiple pick guards as modules to change in and out of the guitar at will with no tools or solder.

  • Patent number: 9697812
    Abstract: When a processor accepts an input of plural notes to be assigned for tone generation, according to a predetermined note determining rule called “assignment type”, the processor selects one or more notes to be sounded in each of plural parts from the accepted notes. The processor controls a display unit to display, for each of the plural parts, the accepted plural notes to be assigned for tone generation. At this time, non-selected one or more notes in respective parts are displayed in one style, and the selected one or more notes in the respective parts are displayed in another style different from the one style. Alternatively, the plural notes to be assigned for tone generation are displayed in one style, and, for each of the plural parts, the selected one or more notes are displayed in another style different from the one style.

  • Patent number: 9697813
    Abstract: A system is described that permits identified musical phrases or themes to be synchronized and linked into changing real-world events. The achieved synchronization includes a seamless musical transition—achieved using a timing offset, such as relative advancement of an significant musical “onset”, that is inserted to align with a pre-existing but identified music signature, beat or timebase—between potentially disparate pre-identified musical phrases having different emotive themes defined by their respective time signatures, intensities, keys, musical rhythms and/or musical phrasing. The system operates to augment an overall sensory experience of a user in the real world by dynamically changing, re-ordering or repeating and then playing audio themes within the context of what is occurring in the surrounding physical environment, e.g. during different phases of a cardio workout in a step class the music rate and intensity increase during sprint periods and decrease during recovery periods.
