    摘要: A polarity inversion control section (9) supplies a polarity designation signal, which designates a polarity of a data signal, to a data line drive circuit (5) while reversing a polarity of the polarity designation signal every frame. Even in a case where a pause driving control section (8) receives a designation signal that designates a sum of the number of frames constituting a scanning period and the number of frames constituting a pause period to be an even number, the pause driving control section (8) maintains the sum of the number of frames constituting a scanning period and the number of frames constituting a pause period to be an odd number.

    摘要: An object of the present invention is to provide a display device which includes a power supply circuit capable of supplying a current necessary for driving a large or high-definition display panel for example, and also is suitable in low power consumption configurations implemented by intermittent driving for example.A DC-DC converter (600) generates a supply voltage VPW1, etc. for supplying to a drive circuit (500), by converting a voltage level through an operation of a switching element which changes an electric current passing through an inductor. A mode control signal Cm is generated in a power supply control section (220) of the display control circuit (200), and is supplied to the DC-DC converter (600), whereby the DC-DC converter (600) is operated in a PFM control mode during a period when a load condition is light such as during a non-refreshing period in an intermittent driving, whereas the mode is changed to a PWM control mode in the other periods.

    摘要: A timing controller (7) controls a display module (2) which carries out a scanning process to display a picture based on a picture signal. The timing controller (7) is configured such that when a display signal reception section (20) no longer receives the picture signal, an operation determination section (21) determines the scanning process should be paused, and a timing generation section (22) instructs drive circuits (4, 5) to pause the scanning process in a display panel (2a).

    摘要: In one embodiment of the present application, a display controller is capable of changing a refresh rate, indicative of how often a screen displayed on a display device having a plurality of pixels is switched, between a low refresh rate of 40 Hz and a normal refresh rate of 60 Hz and generates (i) a dot clock (reference clock) serving as a timing signal indicative of a timing of operation in the display device, (ii) video data indicative of an image to be displayed on the screen, (iii) Hsync for defining a horizontal period of a display on the screen, and (vi) Vsync for defining a vertical period of the display on the screen, so as to supply the dot clock, the video data, Hsync, and Vsync to the display device, wherein the display controller includes a dot clock generation circuit for generating the reference clock whose frequency is constant without depending on a change of the refresh rate. This makes it possible to provide the display controller which can suppress occurrence of noise also in switching the refresh rate and which does not allow any screen derangement which is caused by the noise.
