Abstract: A driver is provided for driving a plane fluorescent panel as a backlight source in a small liquid crystal television receiver. The panel is driven with a pulse signal controlled such that a first edge of the pulse signal which is a rise or fall edge of the pulse signal is within a front porch of a horizontal blanking period of a video signal and that a second edge of the pulse signal which is a fall or rise edge of the pulse signal is within the width of a horizontal synchronous pulse to thereby drive the fluorescent panel efficiently to provide a stabilized light emission and render it difficult for noise in the fluorescent panel to enter the display of the television receiver. A small liquid crystal television receiver with a plane fluorescent panel driven so is also provided.

Abstract: Each of a plurality of segment drivers for driving a liquid crystal display panel used in an electronic device includes a display data memory corresponding to a display image plane. The display memory is supplied with an X address and Y address from an address register so that the data write area thereof can be specified. A control device of the electronic device outputs address data and display data to a connection bus when data is stored into the display memory, and the segment driver writes transfer data into an addressed area when it is determined that the write-in process is effected for the segment driver itself by decoding address data by use of a decoder. When data stored in the display memory is displayed, the Y address is automatically incremented in synchronism with a common signal by an increment circuit, and data of one line specified by the Y address is simultaneously read out from an output port of the display memory, converted into a segment signal via a latch circuit and output.

Abstract: A temperature detection circuit and two RAMs are connected to a conversion circuit for converting image data into voltage designation signals and outputting the signals to a signal electrode driver. The temperature detection circuit detects the temperature of a liquid crystal display element as one of conditions which influence the behavior of liquid crystal molecules. One RAM is used to store a conversion table in which voltage designation signals for designating effective voltage to be applied to a liquid crystal layer are preset for image data for each predetermined temperature range of the liquid crystal display element. The other RAM is used to store input image data. In the conversion table, the number of different voltage designation signals in a high-temperature range is set to be smaller than that of different voltage designation signals in a normal temperature range.

Abstract: In a wristwatch type distress message sending device worn by the user, a positional information generator receives GPS signals sent by a plurality of GPS satellites and generates positional information on the latitude and longitude of the position of the user. When the user meets a disaster, a distress message signal generator generates a distress message signal containing the positional information generated by the positional information generator. A sender then sends out the distress message signal by radio.

Abstract: An electronic device maintains data utilizing a ferroelectric memory, not requiring a backup power source voltage. Data such as schedule data and telephone number data is stored in a ferroelectric RAM which switches between a dynamic mode and a nonvolatile mode. When a clock mode is designated by a "CLK" key, a memory control circuit causes the ferroelectric RAM to be switched to the nonvolatile mode to maintain the data stored therein. When a schedule mode or a telephone mode is designated by means of a "Sch" key or a "Tel" key, the ferroelectric RAM is switched to the nonvolatile mode to write/read data therein/therefrom. When it is detected that a battery voltage is lowered or the battery is removed from the electronic device, the ferroelectric RAM is switched to the nonvolatile mode to protect the stored data.

Abstract: An image display circuit supplies gray scale data according to a video signal to a liquid crystal panel to present a gray-scaled display and scans the liquid crystal panel N times during one field period of a video signal. The image display circuit includes a table ROM comparing a current video signal with a previous video signal of one frame before, and generates gray scale data for N times in accordance with the comparison result. Gray scale data greater than the gray scale of the current video signal is generated when the comparison result indicates that the gray scale of the current video signal is greater than that of the previous video signal, and gray scale data smaller than the gray scale of the current video signal is generated when the gray scale of the current video signal is found to be smaller than that of the previous video signal. Based on the generated gray scale data, the liquid crystal panel is driven with the proper gray scales.

Abstract: A cartridge detector detects information on the color of a label tape of a cartridge which is a printing medium on the basis of the shape of the cartridge. A controller determines the color of the label tape on the basis of detected information obtained from the cartridge detector. The controller controls a display through a display control unit and displays the background of a display screen in the same color as that of the label tape determined on the basis of the detected information obtained from the cartridge detector. A key-in unit inputs to the printer printing data (for example, character, illustration data, etc.) and their print color data. The controller controls the display through the display control unit to display in the print color specified by the key-in unit the printing data input from the key-in unit in the screen background having the same color as the label tape. The input printing data is printed on the label tape by a printing unit through the print control unit.
