Abstract:
An information processing device including a display unit and an input unit is driven by a first step of inputting an input signal from the input unit, a second step of starting to move an image displayed on the display unit, a third step of lowering luminance of the image, a fourth step of checking whether the image reaches a position of predetermined coordinates, a fifth step of increasing the luminance of the image in the case where the image reaches the position of the predetermined coordinates, and a sixth step of stopping moving the image so as to perform eye-friendly display with the display unit.
Abstract:
A method for driving an information processing device which is adaptable to a wider variety of input methods is provided. The coordinates of an operating body at a starting point in the XYZ space and the coordinates of the operating body at an ending point in the XYZ space after a certain period of time are obtained, and the Z coordinate at the ending point and the movement distance on the X-Y plane in the certain period of time are calculated. Then, a signal is output only in the case where both the distance from an operating surface to the operating body in the vertical direction and the movement distance in the horizontal direction exceed the respective threshold values. In this manner, input operation can be performed by a three-dimensional motion, which includes movement of the operating body in the vertical direction as well as in the horizontal direction.
Abstract:
A light emitting device comprises a pair of electrodes and a mixed layer provided between the pair of electrodes. The mixed layer contains an organic compound which contains no nitrogen atoms, i.e., an organic compound which dose not have an arylamine skeleton, and a metal oxide. As the organic compound, an aromatic hydrocarbon having an anthracene skeleton is preferably used. As such an aromatic hydrocarbon, t-BuDNA, DPAnth, DPPA, DNA, DMNA, t-BuDBA, and the like are listed. As the metal oxide, molybdenum oxide, vanadium oxide, ruthenium oxide, rhenium oxide, and the like are preferably used. Further, the mixed layer preferably shows absorbance per 1 μm of 1 or less or does not show a distinct absorption peak in a spectrum of 450 to 650 nm when an absorption spectrum is measured.
