ABSTRACT:
Disclosed is a multi-layered PCB of mobile communication terminals that may improve ESD protection of LCD through efficiently protecting LCD signal lines such as data lines and control lines from ESD.According to the present invention, the efficient arrangement of GND regions around the LCD signal lines improve ESD features of sub-LCD and main-LCD and reduce defects by ESD, so that reliability of mobile communication terminals may be improved and the mobile communication terminals may stably operate against unexpected situation. Accordingly, it is possible to improve quality of mobile communication terminals and to reduce manufacturing cost due to efficient PCB arrangement.
