From a visual-interface-enabled voice-network-operative telephone device, a user navigates an Internet based address-book, and upon finding a desired record in the address-book, the user will cause a server associated with the address-book to initiate a call or a message to a device associated with the electronic address stored in the record (e.g. telephone number, VOIP address, email address, etc.). This is done by the server (A) receiving access to an internet accessible address-book; (B) accepting a dial-up connection from a user, wherein the dial-up is from a visual-interface-enabled voice-network-operative telephone device; (C) receiving navigation commands from the device; (D) sending at least one portion of a record in the address-book to the device; and optionally thereafter accepting a communications command from the device relating to an electronic address sent by the server to the device to establish a voice connection with the address or to send a message to the address.

A reproduction device has at least one screen for displaying information, with at least four sound reproduction devices respectively at the corners of the screen, which are separately driven depending on the local screen position of a user-relevant item of information such that direction information relating to the screen information is conveyed to the user by the resulting acoustic signal that is produced by the combined, individual driving, which is perceivable by the user.

A liquid crystal display of a large screen size, a slim thickness and light weight is disclosed. The liquid crystal display includes a light supply unit group having at least two light guiding plates arranged in parallel and at least one lamp unit coupled to one side of the light guiding plate. A light control element is mounted on an upper surface of the light supply unit group, and uniformly controls luminance between the light guiding plate and the lamp unit. A reflective plate is disposed on a rear surface of the light supply unit group and has a shape corresponding to the rear surface of the light supply unit group. A back light assembly includes a receiving container that receives the light supply unit group, the light control element, and the reflective plate.

In a light-emitting device where reflective electrodes are regularly arranged, occurrence of interference fringes due to reflection of light reflected by the reflective electrode is inhibited. A surface of the reflective electrode of a light-emitting element is provided with a plurality of depressions. The shapes of the plurality of depressions are different from each other and do not have rotational symmetry. Irregularity of the surface shape of the reflective electrode is increased, which inhibits interference of light reflected by the reflective electrode. To form the plurality of depressions in the surface of the reflective electrode, for example, a surface of an insulating layer that is a base of the reflective electrode is made uneven. Reflecting the surface shape of the insulating layer, the reflective electrode has an uneven surface.

A variable-sized screen includes a support, at least one scrolling device and a flexible display. The support has a fixing frame and a movable frame, which are retractably connected. The scrolling device and the flexible display are assembled on the support. The flexible display is wrapped around the support, and the size of the flexible display is variable due to displacement of the support. When the support changes size through a retracted movement of the movable frame and the fixing frame, the flexible display also changes size correspondingly and the size of the screen becomes variable. Therefore, the dimensions of the screen and electronic products are not limited, and the display device has the advantages of a big screen yet is still portable and convenient for a user.

An information display apparatus which has a liquid crystal display which uses chiral nematic liquid crystal with a memory effect and can be driven by a matrix driving method. The screen of the display is divided along a scanning line into a still picture display area and a motion picture display area. The information display apparatus may have a first display and a second display on one screen. The first display is a reflective type liquid crystal display with a memory effect, which has an advantage of saving energy, and is used exclusively to display a still picture. The second display is a liquid crystal display which requires only a short time for writing. Information to be written in a short time, such as inputted information, is displayed on the second display.

There is provided an information processing apparatus including a display part to display video content on a screen, a rotation angle detection part to detect a rotation angle of the screen, a display formation determination part to determine a display formation of video content at any rotation angle of the screen or during transition of the rotation, and an image processing part to perform an image processing in accordance with the display formation determined by the display formation determination part such that the video content is conformed to the screen which is tilted by the rotation angle detected by the rotation angle detection part.

To provide a display device with higher image quality and reliability or a large-sized display device with a large screen at low cost with high productivity. A function layer (such as a coloring layer or a pixel electrode layer) used in the display device is formed by discharging a liquid function-layer-forming material to an opening formed with a layer including a first organic compound which has a C—N bond or a C—O bond in the main chain as a base and a layer including a second organic compound as a partition. The fluorine density exhibiting liquid repellency to the liquid function-layer-forming material, which is attached to a surface of the layers including organic compounds, is controlled, whereby a liquid repellent region and a lyophilic region can be selectively formed.

A line inverse driving method is performed by outputting voltages for gradation display in mutually reverse polarities with respect to pixels adjacent in a data signal line direction. A separation switch is provided between an output stage of a data driver and a data signal line to separate them. In a blanking period, the data signal line is cut off, and in the selection-scanning period of a scanning signal line to be scanned first, the scanning signal line to be scanned next is also subjected to the selection-scanning. With this structure, respective charges in adjacent pixel capacitors are neutralized, and it is therefore possible to reduce a power consumption. Further, since a short-circuit can be performed at short distance, the problem of dull waveform can be suppressed, thereby realizing an image display device suited for a large screen.

A method of wireless transmission of an email having a content in a language unsupported in a mobile communication system by Multimedia Messaging Service (MMS) to a recipient using a mobile phone. An email server receives the email and extracts from the email text information indicative of the recipient and relating to content. A conversion server, connected to the email server, converts the content information from text into an image and composes a MMS message including the image. A MMS message transmitter, connected to the conversion server, transmits the MMS message to the mobile phone. Multi-language (supported and unsupported languages) wireless email transmission is thus made possible.
