Problems solved by technology

[0005] However, if many users' portable telephone devices send requests for content information to the server at the same time, the standby time for connecting to the server will be longer, and thus it will take a long time to receive the requested content information from the server.
This situation can lead to such a problem that the portable telephone device cannot receive the content information within the given time of illuminating the display screen, and when the content information is received, the illumination has been turned off
This creates a situation where the user cannot read the content information even though the content information is displayed on the display

Abstract

When the backlight is turned on, if the control unit detects a key input related to a request instruction from the user according to the request instruction signal sent from the operation unit, the control unit outputs a turn-off instruction signal to the display lighting unit to turn off the backlight, and the detected The request command signal is output to the communication unit. The communication unit transmits the request instruction signal to the server via the base station. If the server responds to the request instruction signal and distributes the content information to the communication unit via the base station, and the communication unit outputs the content information within the waiting time, the control unit reproduces the content information, and outputs the reproduced content information to the display unit to display the content information on the display unit. on the display screen of the display unit, and output a lighting command signal to the display lighting unit to turn on the backlight.
