摘要:
An object of the invention is to provide a display device that allows its useful life to be prolonged without letting the user of the device conscious of changes in the display state of the display device, and the power consumption to be prevented from increasing, and the usable time without charging to be prevented from being shortened even when a light emitting display device is used. The display device is driven by a power source chargeable by connection with an external power source and includes a display portion (4), a display control portion (31) that switches between an inverted display state and a non-inverted display state of said display portion (4), and a power source detection portion (5) that detects a connection with said external power source. The display control portion switches between the inverted display state and non-inverted display state of said display portion (4) when said power source detection portion (5) detects a connection with said external power source.

L'invention concerne un dispositif de radiocommunication comprenant au moins une source lumineuse (11, 213) pour indiquer au moins deux états distincts du dispositif, et dont la luminosité varie selon des rythmes différents selon les états. Dans au moins un premier des états, la source lumineuse est contrôlée par un signal numérique (30, 70) sensiblement périodique alimentant des moyens d'intégration (200, 201, 202, 54, 601, 602, 603, 604, 80, 82) qui lui sont connectés.

A system and method of ambient light detection with digitized output. A light sensitive device is coupled to electronic circuitry for receiving an output of the light sensitive device corresponding to a level of ambient light. The electronic circuitry compares the output to a threshold level. The threshold level corresponds to a desired level of light. The electronic circuitry for provides an output signal indicative of said desired level of light.

For a portable telephone set having a display portion for displaying various information associated with call origination and reception, a gyro for detecting inclination of a main body is provided. When substantially horizontal position of the main body for dialing is detected by the gyro, power supply for the display portion is initiated. On the other hand, when the vertical position of the main body for speaking is detected by the gyro, power supply for the display portion is shut off.

A display device includes a display panel having display pixels arranged in a matrix, and a display area capable of displaying in color. A display mode of the display panel is switched to either a full-screen display mode in which an image is displayed in the entire display area or a partial display mode in which an image is only partially displayed in the display area. The display area of the display panel is set while dividing the display area into a partial display area in which an image is displayed and a background display area in which an image is not displayed in the partial display mode. An image is displayed in the partial display area. A display color of the background display area is set.

A portable communication apparatus includes a main housing having at least a display section and an operation section and a movable housing that is engaged with the main housing slidably in a longitudinal direction between a retracted state and an extended state. The main housing and the movable housing are urged in an extension direction and are releasably locked in the retracted state. A portion of the display section is covered and protected by the movable housing when retracted. An optical aperture for optical function is provided in the main housing and its optical function is made operable when extended.

An energy-conserving mobile station and a means for reducing the energy consumption of a mobile station and to reduce burn-in on the display element, where a part of the liquid crystal display element (LCD) of a mobile station is switched off, when the whole display element is not needed and a limited amount of information is displayed on the switched-on part of the display element (A1). An arrangement according to the present invention can be implemented by e.g. driving the control circuit (DC) of the liquid crystal display that supports the partition of the display element to switch of certain rows of the display element in energy conservation mode and switching them on to be used, when information is desired to be displayed on all of the display element.

An electroluminescent display device having a configuration hardly generating variations in the current value due to a deteriorated EL element is to be provided. A capacitance element is disposed between the gate and the source of a driving TFT, video signals are inputted to the gate electrode, and then the gate is put in a floating state. At this time, when the gate-source voltage of the driving TFT exceeds its threshold, the driving TFT is turned on. Suppose an EL element is deteriorated and the anode potential rises, that is, the source potential of the driving TFT rises, the potential of the gate electrode of the driving TFT, being in a floating state by coupling with the capacitance element, is to rise by the same amount. Accordingly, even when the anode potential rises due to the deteriorated EL element, the rise is added to the gate electrode potential as it is, and the gate-source voltage of the driving TFT is allowed to be constant.
