  • Patent number: 11953738
    Abstract: The present invention discloses a display including a display panel and a light redirecting film disposed on the viewing side of the display panel. The light redirecting film comprises a light redistribution layer, and a light guide layer disposed on the light redistribution layer. The light redistribution layer includes a plurality of strip-shaped micro prisms extending along a first direction and arranged at intervals and a plurality of diffraction gratings arranged at the bottom of the intervals between the adjacent strip-shaped micro prisms, wherein each of the strip-shaped micro prisms has at least one inclined light-guide surface, and the bottom of each interval has at least one set of diffraction gratings, and the light guide layer is in contact with the strip-shaped micro prisms and the diffraction gratings.

  • Patent number: 9558698
    Abstract: A driving method for driving a display apparatus including a plurality of pixels, a plurality of data lines and a data driver. The data driver includes a first latch outputting a first sample data signal to a second latch, the second latch, a first charge sharing line and a second charge sharing line. The method includes performing a first charge sharing when a polarity of one of the pixels changes so as to output a first calibrated data signal to the data line electrically coupled to the pixel, and executing a second charge sharing when the most significant bit of the first sample data signal is different from the most significant bit of the second sample data signal so as to output a second adjusted data signal to the data line.

  • Patent number: 9344267
    Abstract: A data receiver includes a serial-data processing module, a null-frequency detecting unit, a data checking unit, a status control unit and a timeout checking unit. The serial-data processing module receives serial data, generates an operation clock, parallel data and required data, and determines whether the operation clock is correct for accordingly generating a first result. The null-frequency detecting unit receives the operation clock and determines whether the operation clock is locked or null for accordingly generating a second result. The data checking unit is enabled according to the first result and determines whether checking data of the required data is correct for accordingly generating a third result. The status control unit outputs a frequency-locked signal and changes the signal state of the frequency-locked signal according to the first to third results. The enabled timeout checking unit resets the serial-data processing module according to the signal state of the frequency-locked signal.
