摘要:
A liquid crystal display wherein display is performed based on the fact that an a.c. voltage is applied to a liquid crystal layer when a switching element establishes a connection between a display electrode and a common electrode, and the a.c. voltage is not applied to the liquid crystal layer when the switching element releases the connection between the display electrode and the common electrode. A state of the switching element changes from connection between the display electrode and the common electrode to release of the connection under a condition that respective voltages of an opposite electrode, the display electrode, and the common electrode are made substantially the same, the condition being produced by stopping an a.c. voltage applied to the opposite electrode.

An emissive display using an organic electroluminescent device is provided, in which the pixel circuit is simplified, the aperture ratio is increased, high resolution is achieved, and the power consumption is reduced. In the configuration, among the two sets of inverter circuits, one set of inverter circuit is formed by a circuit connecting an organic electoluminescent device and a transistor in series, and a transistor of a memory circuit is omitted. Also, in the mutual connection of the two sets of inverters, display data is inputted to a line connected to the gate of the transistor connected in series with the organic electoluminescent device, and owing to this connection, the write load is reduced, and the high resolution is achieved by enabling to write at high speed.

The present invention provides a system for performing procedures to request repair, without troubling the driver, when a car breaks down, as well as various onboard peripheral apparatuses and cellular phone used for this system. This system comprises an onboard peripheral apparatus having a failure detector, an onboard main controller for managing car information, a cellular phone which can make wireless connection to the onboard main controller, and a response center for receiving requests for car repairs and maintenance and making arrangements therefor. When a failure is detected, repair request is transmitted to the response center through wireless communication together with the user ID of the driver. Based on this request, the response center acquires remedy information from a car manufacturer and makes arrangements for repair and provides this remedy information to a repair shop.

An image display for displaying image data on an image display part constructed by a display pixel array is disclosed. In an image display in which image data input means for inputting image data so that the display pixel array has two neighboring areas having different frame rates (>0) is provided or image data is displayed on an image display part constructed by a display pixel array, there is provided image data input means which can input at least one moving image data and at least one still image data into the image display part at different frame rates (>0). A high precision image display can be realized hardly changing a display pixel rewriting speed.

A liquid crystal active matrix display device includes a first substrate having a thin film transistor formed thereon. A light-screening film 1 is located on the first substrate in a manner to be overlapped with an ITO. The display device includes a second substrate having a color filter and a light-screening film 2 formed thereon. The second substrate is opposed to the first substrate. The light-screening film 2 extends from the uncontrollable area by a certain value depending on a voltage from the external, resulting in improving a numerical aperture.
