摘要： An image display apparatus includes an image display section in which a plurality of light emitting elements are arranged in a matrix at intersections of a plurality of scan lines and a plurality of data lines. A control circuit selects one of modes as an operation mode in response to a mode switching signal, and outputs a data signal and a scan control signal based on an image signal to be displayed and the selected mode. A row driving section is connected to the plurality of scan lines to sequentially drive the plurality of scan lines based on the scan control signal in a unit determined based on the operation mode. A column driving section is connected to the plurality of data lines to sequentially drive the plurality of data lines based on the data signal. In this way, an image corresponding to the image signal is displayed on the image display section.

摘要： A picture displaying apparatus that includes scanning lines to which scanning signals are inputted, data lines to which data signals are inputted, and a light emission element present at every intersection of scanning lines and data lines. The designated picture displaying device also consists of a display unit composed of light emission elements and a memory unit containing memory cells that store single units of display data. The units of display data are read from the memory unit in different orders and then written to the picture displaying unit such that the picture or content is different for each predetermined frame or frames. A plurality of display data corresponding to different display contents is generated without a calculating circuit when the screen saver function is activated.
