摘要： PROBLEM TO BE SOLVED: To make the luminance when an ordinary display is switched to a dimming display lower than heretofore in an organic EL display device. SOLUTION: In performing the ordinary display, a signal electrode driver passes a first constant current to a scanning electrode of a selected column from a signal electrode. At that time, the period of time during which the current is passed in order to display a pixel at the maximum gradation within a selected period is defined as T 1 [μs]. In performing the dimming display, the signal electrode driver passes a second constant current smaller in the current value than the first constant current. The period of time during which the current is passed in order to display the pixel at the maximum gradation within the selected period is defined as T 2 [μs] and the relation T 1 >T 2 is made to hold. When the luminance in the dimming display is made further lower, an FRC is combined as well. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a driving method of a phase modulation element having low speckle contrast of a displayed video, to provide a phase modulation element having simplified structure and to provide a projection display.
SOLUTION: The phase modulation element where transparent electrodes each comprising three or more stripe electrodes formed on a surface of a transparent substrate are opposed to each other so that longitudinal directions of the stripe electrodes are orthogonal to each other on the surfaces of the two transparent substrates, and a liquid crystal is held between the two transparent substrates, is given two or more patterns different at least in time so that phases of light transmitted through partitions adjacent to each other are made different using a driving method of a dot matrix system. Accordingly, speckle contrast can be suppressed. Simplification of electric wiring lines of the phase modulation element and miniaturization of a voltage controller can be achieved by sharing the electric wiring lines connected to the plurality of stripe electrodes and the voltage controller.
