  • Patent number: 9837038
    Abstract: A display panel uses demultiplexers to reduce numbers of data lines, and divides the data lines into groups being coupled to the demultiplexers respectively. The demultiplexers are disposed along an edge of the display region and compliant to the outline of the display panel, so as to save the layout space. In addition, the layout of control lines of the demultiplexers can be configured to more effectively utilize the layout space in the layout region. Furthermore, the aforementioned layout helps reduce the length of the conductive lines, and improves the transmission of signals in the conductive lines.

  • Patent number: 9830871
    Abstract: A method for driving a display panel having a variable refresh rate is disclosed. The method comprises detecting a condition that results in a charge accumulation in the display panel using an accumulated difference in time duration between frames of positive polarity and frames of negative polarity received from an image source. The DC imbalance is a result of a frame pattern comprising alternating frames of differing polarities, wherein frames of positive polarity within the frame pattern are of a different time duration than frames of negative polarity, and wherein the frame pattern results in an accumulation of charge in pixels of the display panel. The method also comprises correcting for the charge accumulation by disrupting the frame pattern.

  • Patent number: 9823758
    Abstract: A computer system has a touch sensitive display screen within a housing and a touch sensor, which is coupled to a bus. A processor and a memory are coupled to the bus. The housing has a channel for receiving and storing a stylus. A sensor is disposed adjacent to the channel. The sensor interacts with the stylus through the Hall effect caused by a magnet within the stylus and is thus operable for detecting a presence or absence of the stylus without physical contact therewith. The memory has an application which, when executed on the processor, automatically performs one or more stylus related software functions upon a reported absence of the stylus from the channel. One of the software functions includes palm detection rejection with respect to data from the touch sensor. Another function includes display of a GUI displaying a listing of applications that are based on stylus data entry modes. Another function includes setting up OS modes designed for accurate operation of stylus data entry.
