  • Patent number: 11587479
    Abstract: The present disclosure provides a display panel and a display device. The display panel includes a border region, an optical component region, and a main display region. The border region is provided with multiple load compensation units. At least one first data line is electrically connected to M load compensation units, so as to compensate for a load of the first data line, making the compensated load on the first data line and a load on the second data line are basically the same or tend to be the same. In this way, any display difference across different regions of the display panel due to a difference of the load on the first data line and the load on the second data line may be avoided, which in turn improves the display uniformity of the display panel and improves the display effect of the display panel.

  • Patent number: 11575049
    Abstract: One of the objects is to improve display quality by reduction in malfunctions of a circuit. In a driver circuit formed using a plurality of pulse output circuits having first to third transistors and first to fourth signal lines, a first clock signal is supplied to the first signal line; a preceding stage signal is supplied to the second signal line; a second clock signal is supplied to the third signal line; an output signal is output from the fourth signal line. Duty ratios of the first clock signal and the second clock signal are different from each other. A period during which the second clock signal is changed from an L-level signal to an H-level signal after the first clock signal is changed from an H-level signal to an L-level signal is longer than a period during which the preceding stage signal is changed from an L-level signal to an H-level signal.
