摘要： A polarity of a POL outputted from a polarity inversion control section (9) is always identical between a scanning period and a pause period immediately subsequent to the scanning period, and is reversed every time switching from a pause period to a scanning period is carried out. This makes it possible to both carry out pause driving and prevent image sticking on a display panel.
摘要翻译：从极性反转控制部（9）输出的POL的极性在扫描期间和扫描期间之后的暂停期间总是相同的，并且每当从暂停期间切换到扫描期间时，反转。这使得可以进行暂停驱动并防止图像粘在显示面板上。

摘要： A sum of the number of frames constituting a scanning period and the number of frames constituting a pause period is an even number. A polarity of a POL signal in each frame in each of the scanning period and the pause period is reversed every frame. Further, the polarity of the POL signal is reversed at a timing when switching from the scanning period to the pause period is carried out, and is maintained at a timing when switching from the pause period to the scanning period is carried out. Alternatively, the polarity of the POL signal is maintained at a timing when switching from the scanning period to the pause period is carried out, and is reversed at a timing when switching from the pause period to the scanning period is carried out.

摘要： A display device; a method for driving the display device; and electronic equipment, each enabling a detection device to perform detection with a frequency higher than a refresh frequency of the display device and with improved accuracy are provided. The display device has a screen including pixels and repeatedly alternates between a scanning frame during which the pixels are scanned to be sequentially brought into a selected state and a pause frame during which the pixels are not scanned, and includes a detection instructing circuit configured to output detection operation control signals corresponding to touch panel detection periods to the detection device in at least one pause frame. The detection instruction signal instructs the detection device to detect at least one of detection targets which are input by touching or approaching the screen and a radio wave coming from outside the display device.

摘要： A memory access section 16 writes, in a memory (10), a received image signal, in a case where a current frame is one that is located right before a frame in a scanning signal. On the other hand, the memory access section 16 does not write, in the memory (10), a received image signal, in a case where the current frame is one that is located right before a frame in a pause period. This allows a further reduction in electric power used to write, in the memory (10), an image signal received from outside.
摘要翻译：在当前帧是位于扫描信号中的帧正前方的帧的情况下，存储器访问部分16在存储器（10）中写入接收到的图像信号。另一方面，在当前帧是位于暂停期间的帧之前的位置的情况下，存储器访问部分16不在存储器（10）中写入接收到的图像信号。这允许在存储器（10）中进一步减少用于写入从外部接收的图像信号的电力。
