  • Patent number: 8952880
    Abstract: A display panel drive circuit includes a shift register constructed of unit circuits connected in stages. The unit circuits generate signal line selection signals, respectively, which signal line selection signals are made active for a respective certain period of time to form a respective pulse, and the pulses are outputted successively from respective unit circuits in order of ordinal number starting from a first stage until an end stage. In at least one embodiment, each of the unit circuits receive (i) clock signals generated based on a sync signal received from outside of the display panel drive circuit, (ii) a start pulse signal generated based on the sync signal, or a signal line selection signal generated in a stage different from its own stage, and (iii) a clear signal. The clear signal is made active in a case where anomalousness is included in the sync signal, and no pulse is outputted from the shift register until a subsequent vertical scanning period starts.

  • Patent number: 8648889
    Abstract: In one embodiment of the present invention, in an even-numbered signal line group, the arrangement sequence of the first and second signal lines is reversed between in a display area and in a non-display area, and the same goes for the arrangement sequence of the third and fourth signal lines. The ends of the first to sixteenth signal lines in the non-display area are connected to the first to sixteenth individual drivers, respectively. An odd-numbered individual driver and an even-numbered individual driver each output a corresponding one of drive signals of opposite polarity. Thus, the polarities of subpixels of the same color arranged in a first direction D1 (horizontal direction) differ between the subpixels connected to the odd-numbered signal line group and the subpixels connected to the even-numbered signal line group. That is, all of the subpixels having the same color arranged in the horizontal direction do not have the same polarity. This helps reduce a horizontal shadow.
