Definitions
- touch panel devices have their disadvantages by type, and therefore, they can not be used without problems for all applications.
- the electromagnetic method uses a magnet of Faraday's law and an electromotive force generation principle, and calculates coordinates by determining the amount of current flowing through the coil for each position. Since the AC signal must be applied to the coil, there is a disadvantage that a special dedicated pen is required.
- the digital method applies an AC signal along the X-axis and the Y-axis of the grid shape to which the sensor electrode 20 is connected, and at this time, changes the amount of change of the microcurrent transmitted through the finger to Y. Measurements are made on the axis and the X axis, respectively, to recognize the position at the point where the most change occurs as the finger contact position.
- the large digital method does not have at least two or three electrode signals as shown in FIG. 7, and thus a Gaussian function cannot be applied.
- 7 is a view showing a coupling (coupling) characteristics of the capacitance according to the conventional digital system implemented in large format.
- FIG. 2 is a view showing a digital electrode structure according to the prior art.
- FIGS. 10 and 11 are cross-sectional views schematically illustrating the capacitive touch panel of the high sensitivity digital method according to the present invention, respectively.
- the other end is electrically connected to an external terminal portion electrically connected to each of the two pairs of position sensing main sensor electrodes, And a plurality of machine direction is connected to the bridge electrode is characterized by including a sub-electrode for position detection formed in the other direction.
- first and second position sensing main sensor electrodes 501 and 502 are formed in plural, and each of them is electrically connected to the bridge electrode 600.
- the shielding electrode 900 is disposed to remove noise from an electronic system, such as a display device thereunder. However, when the influence of the noise from the electronic system is small, this may be omitted.
