Abstract

The display device according to the present invention includes an inaction control circuit and a DCK-PLL circuit. The inaction control circuit stops driving of driving circuits, such as a signal line driving circuit, a scanning line driving circuit, analog circuit and the like, which are provided for driving an active matrix panel. The inaction control circuit stops the control circuits in a non-refresh period where all scanning lines become non-scanning state and provided between refresh periods for scanning a screen of the active matrix panel. The DCK-PLL circuit generates a clock signal which is used for taking a data signal into a data signal line in the active matrix panel. The inaction control circuit also stops driving of the DCK-PLL circuit in the non-refresh period, in addition to stopping driving of the driving circuits. On this account, since the DCK-PLL circuit consuming great power is stopped in the non-refresh period, the average power consumption of the refresh period and the non-refresh period can be greatly reduced.

Description

technical field [0001] The present invention relates to a display device and a driving method thereof. By applying a scanning signal to a pixel scanning signal line in each row, selecting each row of a screen of a display part in which pixels are arranged in a matrix, and scanning the above screen, data signal lines The data signal is supplied to the pixels of the selected row and displayed. Background technique [0002] usually for example Figure 10 As shown, the active matrix display device includes: an active matrix display screen 101 with pixels arranged in a matrix, a signal line driver circuit 102 for driving data signal lines (not shown) in the screen 101, and driving the The scanning line driving circuit 103 for scanning lines (not shown) in the screen 101, the frame memory 104 storing the digital image signal transmitted to the above-mentioned signal line driving circuit 102, and generating the digital image signal on the above-mentioned signal line driving circuit...

AI Technical Summary

Problems solved by technology

[0024] If the proportion of the above-mentioned non-renewal period is increased, although the average power consumption can be reduced, the power consumption during the non-renewal period can only be very close to 2mw, and the power consumption cannot be reduced any lower. The power consumed by the operating circuit cannot be reduced any more than the power consumed
