In either of a source side and a drain side of an insular semiconductor thin film, a gate electrode is extended without a break along the contour of the insular semiconductor thin film to provide a branch closed circuit, thereby removing a current component path to server as a sub-channel in the edge of the insular semiconductor thin film, in order to eliminate current components due to the concentration of a gate electric field in silicon thin-film edges occurring in edges of an insular semiconductor thin film of top gate type thin-film transistors and a shift of threshold due to fixed charges in the periphery of the silicon thin-file edges.

Disclosed herewith is an information terminal provided with a function for displaying image data. An electromagnetic wave output from a main device provided outside the information terminal is received by an antenna and converted to a binary signal by a wave detection circuit. Using the signal obtained by this wave detection circuit, a power supply circuit generates a power for driving a processor, a memory, a display part, a data line driving signal, a data line driving signal, and a timing controller. The processor decodes the signal received by the wave detection circuit and stores the received information in the memory. The timing controller generates control signals of the data line driving circuit and the scanning line driving circuit, as well as image data so as to display images on the display part.

The voltage-current property of the specific pixel is measured to store the data on a single line in a line memory. The property data of adjacent pixels are compared. A failure determination unit detects whether or not the pixel to be compared is faulty. If it is determined as being faulty, the faulty pixel is removed from the pixel group to be compared. The burn-in determination unit performs the comparison using normal pixels only to provide the correct burn-in data. The calculation unit reflects the burn-in data in the image data from the host.
摘要:
An image display device for displaying a screen containing both moving image data, and image data stored in the internal memory with lower power consumption. The image display device contains a switch for controlling transfer to a display area for image data stored in the internal memory installed outside the display area, and a switch for controlling transfer to a display area for image data (such as moving image data) other than the image data stored in the internal memory. The image display device controls switching according to the display position of both image data types.

A data driver circuit which enables the square measure of the non-display areas of image display devices to be reduced is to be provided. The driver circuit has two DA converters which convert the digital signals, in accordance with more significant bits thereof, into analog voltages; a voltage divider which divides the output voltages of the two DA converters in accordance with less significant bits of the signals; and a shift register which generates trigger signals in synchronism with the digital signals. The voltage divider, arranged in the gap between the two DA converters, comprises memory elements arrayed in two-dimensional matrixes, and a plurality of resistive wirings. The memory elements store decoded signals generated by the decoders in synchronism with the trigger signals, and selectively supply, in accordance with the decoded signals stored by the memory elements, the divided voltages which derive from the two DA converters and are generated on the resistive wirings.
