Abstract:
A portable radio terminal comprising:a radio transmitting and receiving means for transmitting and receiving a radio data; a memory means for storing a display data; a control means receiving data received by said radio transmitting and receiving means, to generate a display data and to write said display data into said memory means; a liquid crystal display means for visually displaying said display data; and a display control means reading out said display data from said memory means for controlling said liquid crystal display means to cause said liquid crystal display means to visually display said display data, said display control means outputting a liquid crystal alternating signal to said liquid crystal display means at each time an image displayed in said liquid crystal display means is changed from one frame to a next frame, thereby to invert an angle of a liquid crystal in said liquid crystal display means, wherein when a radio data receiving period overlaps the timing of outputting said liquid crystal alternating signal, said display control means defers the outputting of said liquid crystal alternating signal until said radio data receiving period ends, whereby the angle of the liquid crystal in said liquid crystal display means is not inverted until said radio data receiving period ends.
