  • Patent number: 11195493
    Abstract: One or more embodiments are directed to compensating for a long horizontal blank (LHB) period. Using a first display data value, a compensation amount is determined from a mapping between display data and compensation amounts. The first display data value is for a display row after an LHB period in a display frame of a display panel. A second display data value is adjusted with the compensation amount to obtain revised display data value. The revised display data value is outputted for the display panel.

  • Patent number: 9588612
    Abstract: Provided is a display drive circuit which is connected to a display panel including a gate drive circuit that scans gate electrodes, a source driver that drives source electrodes of the display panel, and a gate control driver that supplies a clock signal to the gate drive circuit. The display drive circuit performs an intermittent operation which is alternately provided with a display period in which the source electrodes are driven and an interruption period during which the display panel is not updated. During a start of the display period following the interruption period, the gate control driver extends a pulse width of the clock signal which is supplied to the gate drive circuit, or preliminarily outputs the clock signal before the start of the display period.
