20100128012 | DISPLAY DEVICE,IT'S DRIVING CIRCUIT, AND DRIVING METHOD - One embodiment of the present invention discloses a display device which can use a display element having a relatively large difference between a minimum gradation voltage and a maximum gradation voltage. A first selection period and a second selection period are included in a period (a scanning signal line selection period) in which each gate wiring is selected. In the first selection period, a first selection voltage for allowing every TFT included in a line, which is an object to be selected, to be in an ON state is applied to the gate wiring of the line which is the object to be selected. In a period between the first selection period and the second selection period, a non selection voltage is applied to the gate wiring which is the object to be selected and the voltage of an auxiliary capacity wiring corresponding to the gate wiring which is the object to be selected is changed. In the second selection period, a second selection voltage for allowing a part of the TFTs included in the line, which is the object to be selected, to be in an ON state is applied to the gate wiring which is the object to be selected. | 05-27-2010 |
20100309394 | DISPLAY DEVICE AND DRIVE METHOD FOR THE SAME - At least one embodiment of the present invention aims to provide a display device capable of compensating for a change of a liquid crystal capacitance value for an electro-optic element such as a liquid crystal in accordance with a change of an application voltage to the electro-optic element, without incorporating frame memory. It also aims to improve the response speed of a display device without frame memory. For each pixel formation portion, a frame period is divided into first and second periods. During a frame period in which a target voltage having one of the positive and negative polarities with respect to a potential (Com) of an opposing electrode is to be applied to a pixel electrode, during the first period, a TFT is brought into conductive state and a voltage corresponding to the target voltage is applied to a source line (Sj), thereby providing the pixel electrode with a voltage of the other polarity with respect to the potential (Com) of the opposing electrode, while during the second period, the TFT is brought into non-conductive state and the voltage on an auxiliary capacitance line (Ck) is caused to change from the other polarity to one polarity with respect to the potential of the opposing electrode. | 12-09-2010 |

20110273486 | FIELD SEQUENTIAL COLOR DISPLAY APPARATUS - A backlight unit includes a plurality of light sources whose light-emitting colors can be controlled independently. Each light source is associated with any one of a plurality of areas which are obtained by dividing a display screen. A color signal processing unit determines a chromaticity distribution of a video signal in an area, determines, in color space, a region containing all color coordinates in the area, and determines a light-emitting color of a corresponding light source for each field based on the determined region, and determines a transmittance of a liquid crystal element for each field based on the video signal in the area and the determined light-emitting color. By this, the difference between a color to be displayed and a color actually displayed is reduced area by area, reducing color breakup occurring in a field sequential color system. | 11-10-2011 |
20120188297 | DISPLAY DEVICE - A pixel circuit includes a first sub-dot unit including a thin film transistor and a liquid crystal element, and a second sub-dot unit including thin film transistors and liquid crystal elements. During a selection period, some thin film transistors are turned to an ON state, and in a subsequent voltage adjustment period, another transistor is turned to the ON state. The second sub-dot unit is configured such that when shifting to the voltage adjustment period, a voltage applied to the liquid crystal element changes according to changes in states of the thin film transistors, excluding a case in which a maximum gradation voltage has been applied to the source line during the selection period. With this, for a display device pixels including a plurality of sub-dots, it is possible to set the transmittances of all of the plurality of sub-dots to a level corresponding to the maximum gradation voltage. | 07-26-2012 |

20090231308 | Display Device and Driving Method Thereof - In one embodiment of the present invention, capacitors are provided in series between the source and gate of a transistor which is a driver TFT. A predetermined voltage is applied to contact of the capacitors in a first period so as to apply a data voltage to the gate of the transistor from a source line. In a second period, the transistor is threshold compensated. The contact of the capacitors is opened in the third period, thereby short-circuiting the capacitor to apply a voltage having been subjected to threshold compensation to a point between the gate and source of the transistor. This pixel circuit structure, in which the driver TFT driving an OLED or another current-driven-type display element is threshold compensated, contains a reduced number of elements per pixel to increases the number of display pixels. | 09-17-2009 |
