Abstract: PROBLEM TO BE SOLVED: To efficiently transfer animation information and still picture information by disposing a receiving means which receives the animation information from a host and a communication means which requests the still picture information of the host and receives it, and displaying an image based upon the animation information or still picture information. SOLUTION: Animation data outputted from a host PC to a bus 10 are demodulated by a digital video reception part 1202, written to a frame buffer 1210 by a data control part 1209, and sent to a display part 13 through a digital video transmission part 1211 and displayed. A system control part 1212 controls a high-speed serial I/F control part 1206 to send a request to transfer still picture data to the host PC 11, which sends the still picture data to the request source. The high-speed serial I/F control part 1206 expands the received still picture data by a still picture expansion part 1208 into RGB bit map data, which are written to the frame buffer 1210, sent to the display part 13, and displayed.

Abstract: PURPOSE: To reduce power consumption and to prevent a sense of incompatibility from being given to a user by preventing contrast, etc., from being changed. CONSTITUTION: In a normal plotting mode, an MPU 10 allows prescribe information to display on a liquid crystal panel P by controlling an information signal electrode control part 2 and a scanning signal electrode control part 3 based on the picture information from a host system 6 and the signal from a thermister 20. Then, when the picture information are not changed for a fixed time, the MPU changes over the mode of this device to a static mode to lower the driving voltage to be impressed on information electrodes via the information signal electrode part 2 and lower the driving frequency of the driving voltage. Consequently, power consumption of the liquid crystal panel P is reduced. Moreover, since the driving voltage and the driving frequency in the static mode are set to specific conditions, the changing of contrast accompanied by the changing over of the mode is prevented. Thus, the user never feels a sense of incompatibility to be generated by the changing of contrast of a display screen.
