PURPOSE: An LED display board with a GPS clock is provided to display exact current time regardless of the change of temperature, moisture, and voltage by forming a structure receiving time information through a GPS satellite receiver. CONSTITUTION: An LED module(10) is formed by the arrangement of pixels made of one or more light-emitting devices. A GPS receiver(30) receives the GMT data from a GPS satellite. An operation part(50) computes data GMT data inputted from the GPS receiver. The operation part changes the GMT data into Korean Standard Time. The controller(60) turns on and off pixels of LED modules according to the Korean Standard Time data inputted from the operation part and performs the control operation displaying the current time. The controller displays the current time by controlling the LED module. |
