DUAL TYPE LIQUID CRYSTAL DISPLAY HAVING RFID(RADIO FREQUENCY IDENTIFICATION) FUNCTION

摘要

A dual type LCD(Liquid Crystal Display) having an RFID(Radio Frequency IDentification) function is provided to form an RFID antenna to a flexible PCB(Printed Circuit Board) within an LCD. A mold frame is formed between the first and second LCD panels and has a back light unit. A flexible PCB(120) is formed between the first and second LCD panels and connected with the first and second LCD panels electrically. An RFID antenna(300) is formed on the flexible PCB. The RFID antenna has a radio frequency identification function as a microstrip antenna. The second LCD panel is located at an opening(121) of the flexible PCB. A wire for transmitting signal and a pad for connecting with the first LCD panel electrically are formed on the flexible PCB. The micro strip antenna is wound as a spiral shape along the circumference of the opening by several times. Tow terminals of the micro strip antenna are connected with an RFID module of a portable terminal.
