| 20090167967 | IMAGE WRITING/DISPLAY DEVICE AND IMAGE WRITING/DISPLAY METHOD - An image writing/display device has a voltage applying section, a pressure applying section, an initialization controlling section, and an image writing controlling section. In a state in which a display medium having a pair of electrodes and a display layer that is sandwiched between the pair of electrodes and whose reflectance is changed is positioned, the voltage applying section applies voltage to the pair of electrodes for changing the reflectance of the display layer. The pressure applying section applies pressure for changing the reflectance of the display layer. The initialization controlling section makes the display layer a uniform reflectance by applying pressure to the display layer with the pressure applying section. The image writing controlling section writes an image by applying data voltage from the voltage applying section to specific regions, that correspond to image data, of the display layer between the pair of electrodes. | 07-02-2009 |
| 20090231501 | METHOD FOR DRIVING LIQUID CRYSTAL DEVICE AND DRIVING APPARATUS FOR THE LIQUID CRYSTAL DEVICE - Sequentially performed are (1) an entire liquid crystal layer is initialized into a focal conic state, (2) an image is written onto the liquid crystal device by scanning with selecting exposure or non-exposure while applying a voltage that does not exceed a threshold value for a state change from the focal conic state to a homeotropic state during the non-exposure but exceeds the threshold value during the exposure and that causes the focal conic state and the homeotropic state to be bi-stable after the exposure, and (3) the application of the voltage is stopped to change a state of a portion, of which the state has changed to the homeotropic state, to the planer state. In (2), an electric field energy applied to an exposure portion of the liquid crystal layer is controlled to gradually increase from a start to an end of the series of scanning actions. | 09-17-2009 |
| 20090315820 | METHOD FOR APPLYING VOLTAGE TO PHOTO-ADDRESSABLE TYPE DISPLAY ELEMENT, POWER SUPPLY DEVICE AND DRIVING DEVICE FOR PHOTO-ADDRESSABLE TYPE DISPLAY ELEMENT - A method for applying a voltage to a photo-addressable type display element includes: switching between +V volt and −V volt by a switching circuit to synthesize a rectangular wave pulse of ±V volt; and applying the rectangular wave pulse of ±V volt to the photo-addressable type display element as a bias voltage. When the rectangular wave pulse is to be switched from one of +V volt and −V volt to the other, (i) the rectangular wave is grounded in the course of the switching from the one of +V volt and −V volt to the other, (ii) an output voltage of an output converter, which is not selected after the switching of the rectangular pulse, is changed to about 0 volt, and then, (iii) the rectangular wave pulse is changed to the other of +V volt and −V volt. | 12-24-2009 |
| 20100123840 | LIQUID CRYSTAL DISPLAY DEVICE - A liquid crystal display device, having: a liquid crystal display medium that has a liquid crystal layer disposed between a pair of electrodes disposed facing with each other and that displays an image by reflecting or transmitting outside light according to the orientation of the liquid crystal layer; and an electrostatic actuator disposed at a side opposite to a display surface of the liquid crystal display medium, in which the liquid crystal display device displays an image by changing the orientation of the liquid crystal layer by application of a voltage to a specific area of the liquid crystal display medium through the pair of electrodes according to image data after the orientation of the liquid crystal layer is changed to the planar state by applying a stress to the liquid crystal display medium by the electrostatic actuator. | 05-20-2010 |
