20110273435 | DISPLAY DEVICE AND METHOD OF DRIVING THE SAME - When a light-emitting element emits light for a long time, characteristics thereof change and current flowing therethrough is reduced even in the same voltage is applied. In particular, in a case of a display device with light-emitting element, there is a problem such that burn-in is generated in a display screen. A burn-in correction period in which characteristics of a light-emitting element in each pixel are detected is provided in addition to a normal driving period in which an image is displayed. The light-emitting element can emit light which compensates the changes in the characteristics, by correcting video signals inputted to each pixel in the normal driving period according to the characteristics of the light-emitting elements obtained in the burn-in correction period. | 11-10-2011 |

20090021501 | Light Emitting Device and Method for Driving Thereof - An object of the present invention is to provide a display device consuming lower amounts of power. The display device determines whether or not video signals corresponding to all of pixels in one row of a plurality of pixels are equal to one another. In a case where the video signals corresponding to at least two pixels among the video signals corresponding to all of the pixels in one row of the plurality of pixels, are different from each other, video signals input to an image signal input line are sequentially output to a plurality of source signal lines in synchronization with a sampling pulse output from a shift register. On the other hand, when the video signals corresponding to all of the pixels in one row of the plurality of pixels are equal to one another, input of a start pulse to the source driver is stopped, and the video signals input to the image signal input line are simultaneously output to the plurality of source signal line. | 01-22-2009 |
20140118653 | SEMICONDUCTOR DEVICE AND DRIVING METHOD THEREOF - There has been a problem that power consumption is increased if a potential of a signal line changes every time a video signal is applied to a driving transistor from the signal line, since the parasitic capacitance of the signal line stores and releases electric charges. In a configuration of a display portion provided with a gate signal line for selecting an input of a video signal to a pixel and a source signal line for inputting a video signal to the pixel, a switch is connected in series with the source signal line, the switch being controlled to be in on state when the pixel is not selected by the gate signal line, and in off state when the pixel is selected by the gate signal line. Accordingly, the parasitic capacitance of the source signal line which stores and releases electric charges affects only pixels between an output side of a source driver up to and including the pixel selected to be written with a video signal. Consequently, power consumed by the charging and discharging of the source signal line can be reduced, and thus low power consumption can be achieved. | 05-01-2014 |

In a period during which the gate signal line is not selected, one of the first and second gate driver circuits outputs the non-selection signal to the gate signal line, and the other gate driver circuit outputs neither the selection signal nor the non-selection signal to the gate signal line. | 11-26-2015 |
