Title: TABLET HAVING FLEXIBLE AND TRANSPARENT SENSING AREA
Abstract:
The present invention relates to a tablet having a flexible and transparent sensing area, comprising: an insulating transparent base material having a first loop antenna and a plurality of comb-shaped first line antennas; and a scan substrate having, mounted thereon, a first MUX for selecting one of the ends of the plurality of first line antennas, an amplifier for outputting a potential difference between an output of the first MUX and the first loop antenna, and an MCU for generating a first selection signal and, on the basis of the potential difference from the amplifier, sensing the position of an electronic pen from one line antenna. The first loop antenna formed on the transparent base material is combined with a first conductive pattern formed on the scan substrate, thereby forming a closed loop. Each of the plurality of first line antennas is connected to each of a plurality of first extending patterns insulatively crossing the first conductive pattern on the scan substrate. The plurality of first extending patterns are connected to an input of the first MUX.
