Abstract: A door opening/closing device includes: a motor; and a control unit that is configured to control a rotation rate of the motor by pulse-width modulation (PWM) control. The door opening/closing device opens and closes a door of a vehicle with power of the motor. The control unit is configured to perform the PWM control on the motor at a PWM frequency set so as to deviate from a resonance point of an installation body on which the motor is installed.

Abstract: In an opening control device in a vehicle door, in order to stop the door at a desired position, a control unit stops power supply to a motor, and a short circuit is made in an electric circuit between a first terminal and a second terminal of the motor. In the electric circuit, there is formed a regenerative brake circuit in which regenerative braking can be applied to rotation of the motor. When the door is positioned within a fully-open-position-adjacent range that is adjacent to a fully-open position of the door, regenerative braking is applied to normal rotation of the motor for opening the door and is not applied to reverse rotation of the motor for closing the door.

Abstract: A display apparatus, that can prevent thermal destruction and burning with a simple structure, has been disclosed. In the apparatus it is judged that there is possibility of a pattern, whose area with high brightness is small, being displayed frequently, when a state in which the total light emission pulse number remains large occurs with high frequency, and if such a state is detected, the total light emission pulse number (sustain frequency) is reduced to prevent the thermal destruction and burning.

The driving method includes one specific subfield is arranged to be turned ON early in the one field and always turned ON at luminance level higher than input luminance level “0”, and the specific subfield has a least luminance weight and does not have resetting.

Abstract: A plasma display device has a plasma display panel (PDP), a first driver circuit, and a first flexible cable. The PDP has a first plate on which a plurality of first and second electrodes extending in a first direction are provided and a second plate facing the first plate via a discharge space. Here, the first driver circuit is a circuit which applies a voltage to the first electrodes. Further, the first flexible cable has one end coupled to the first electrodes in a circumference part of the plasma display panel, and has the other end coupled to the first driver circuit inside a circumference of the plasma display panel without folding back the first flexible cable. Consequently, disconnection between the PDP and the driver circuit can be prevented, and reliability of the PDP device can be improved.

Abstract: In the PDP device, for example, two types of SF lighting patterns (A and B modes) are equally divided and arranged in spatially different regions in a field. For example, the patterns are arranged in a zigzag manner in units of pixels. At all lighting steps, existence of an absence of light-on SF which becomes a cause of false contour is permitted only in one mode. Accordingly, a generation rate of absence of light-on SF per field when the modes are combined is low, and the level of false contour can be reduced. Further, the spatial arrangement of each mode is optionally changed among the fields.

Abstract: A display apparatus driving method for a field time division type display apparatus displays grayscale by combining a plurality of subfields into which one field has been divided. Each subfield includes a resetting, an addressing, and a sustaining. At least one extra subfield is additionally provided which does not have a resetting, and which stays always ON with a luminance level higher than a prescribed input luminance level.

Abstract: According to the present invention, a plasma display apparatus, which represents the luminance of one frame in accordance with a combination of plural sub-frames having luminance levels corresponding to a plurality of weighted values, additionally includes a sub-frame having a luminance level lower than the minimum gray scale level of luminance which can be represented by the number of bits in the input video data. Such plasma display apparatus turns on a desired combination of the sub-frames so as to increase the resolution of the luminance without increasing the conventional number of gray scale levels included in the input video data. In a preferred embodiment, especially when the added smaller luminance sub-frame is included in a combination of sub-frames for a low luminance area, the resolution of the gray scale of the low luminance area can be increased, and the representation of gray scale can be enhanced in a low luminance area to which the sight of a person is more sensitive.

Abstract: In an image signal processing unit in a PDP device, a noise reducer unit is provided at a former stage of an error diffusion processing unit. The noise reducer unit has an LPF to input display data and an edge determining unit and a level determining unit to the LPF. Switching between an output which has passed through the LPF and an output which has not passed through the LPF is performed in a data selecting unit according to a pixel region in display data based upon respective determination results, and the selected signal is outputted as output display data. Noise contained in the input display data is reduced by the noise reducer unit while maintaining the fineness of an image. Accordingly, a technology capable of eliminating or reducing noise in display data while maintaining fineness of a display image is provided for digital display.
