    摘要: There is provided a display device capable of displaying an image that barely changes with low power consumption on the basis of video data included in a transmitted command, and there is also provided a method for driving the same. A display timing controller (31) determines every frame period whether or not an externally transmitted command includes updated video data. As a result, when it is determined that no updated video data is included, screen refreshing is paused by not reading video data stored in frame memory (36). Moreover, when it is determined that updated video data is included, the screen refreshing is performed by reading video data stored in the frame memory (36).

    摘要: Provided is a liquid crystal display device with reduced power consumption employing a CS drive method.A CS driver (500) consists of a CS shift register (510) and a CS output portion (520). The CS shift register (510) outputs control signals (COUT(1) to COUT(m)) in accordance with a CS clock signal CCK. The CS output portion (520) outputs auxiliary capacitance signals (CSS(1) to CSS(m)) in accordance with the control signals (COUT(1) to COUT(m)), respectively. An idle period (T2) is set following a scanning period (T1). During the idle period (T2), the CS driver (500) is driven in accordance with the CS clock signal (CCK) at an idle-period CS frequency (fcck2). The idle-period CS frequency (fcck2) is lower than a scanning-period CS frequency (fcck1).
