  • Publication number: 20260111082
    Abstract: Disclosed herein is a touch panel including sensor signal lines with improved resistance uniformity and visibility and a display device including the same. The touch panel includes: a plurality of sensor signal lines each connected to a corresponding one of the touch sensors to transmit a touch signal or a control signal, wherein the sensor signal lines are formed of a transparent conductive material, and at least one of the sensor signal lines includes a plurality of micro-patterns formed by removing the transparent conductive material in a predetermined shape. The touch panel according to the present invention can minimize a difference in resistance between the sensor signal lines, despite differences in length between the sensor signal lines, while improving visibility of the sensor signal lines.

  • Patent number: 12578819
    Abstract: The present invention relates to a touch panel having a resistive compensation pattern. According to an embodiment of the invention, the touch panel includes: a plurality of touch electrodes arranged in a matrix of multiple rows and multiple columns; a plurality of sensor signal lines each connected to a corresponding one of the touch electrodes; and a touch drive integrated circuit (IC) configured to analyze a touch signal of the touch electrode transmitted through the sensor signal line to determine whether the touch electrode is touched, wherein a dummy signal line is constituted in at least one of the sensor signal lines to match resistance of the sensor signal lines belonging to the same row within an allowable tolerance. The present invention also includes embodiments different from the above embodiment.
