发明名称 DISPLAY DEVICE AND ILLUMINATION CONTROL METHOD
摘要 <P>PROBLEM TO BE SOLVED: To provide a display device and illumination control method of providing more effective illumination. Ž<P>SOLUTION: The user turns on a power source (step 401). A control part outputs a power-on signal to turn on a TV broadcast receiver (step 402). A prescribed time after the output of the power-on signal is counted (step 403). When finishing counting, a PWM control part outputs a PWM control signal to an integration circuit located at the post stage (step 404). With delay of the PWM control signal output to the integration circuit, a switching element is gradually shifted to be turned on. A current flowing in the LED elements in an LED unit is slowly increased, accordingly, the LED elements slowly become brighter. The logo part is illuminated with the light from the LED elements, then, the logo part slowly becomes brighter (step 405). Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
