Description

Technical Field [0001] The present invention relates to a pressure sensing device using a touch screen panel,

The present invention relates to a pressure sensing device using a touch screen panel. More specifically, the present invention relates to a pressure sensing device using a touch screen panel, The present invention relates to a pressure sensing device using a touch screen panel that senses a pressure using a hole pattern formed in a region where the touch sensor layers 1 and 2 are overlapped with each other.

In general, a touch screen panel is a screen equipped with a special input device for receiving a position of a touch when the touch is performed by a hand, Refers to a screen that allows the user to directly input data on the screen so that the user can grasp the position of the hand or object and perform specific processing by the stored software.

Such a touch screen panel performs a function by adding a device called a touch sensor to a screen of a general monitor or a mobile device. The touch sensor uses a transparent electrode functioning as Tx and Rx to generate a plurality of rectangular lattices, and an electric field between Tx and Rx is formed in each lattice. The change of the electric field when it touches this grid with the fingertip or other object (stylus pen) causes the change of the capacitance, and by detecting this change, it has the function to grasp the contact position. Therefore, if a character or picture information displayed in advance on the screen equipped with the touch sensor is touched by hand, it is possible to grasp what the user has selected in accordance with the position of the contacted screen, So that the user can obtain desired information. Due to the characteristics of the touch screen panel, it is widely used in public places such as a subway, a department store, a bank, and the like, and is widely applied to terminals for sale in various shops. .

Recently, mobile devices such as smart phones, which are rapidly spreading, are implementing various functions by applying touch sensors. A touch sensor recognizes a touch by using a resistance film method or a capacitance method. Until 2008, the resistance film method has been widely used because it is inexpensive in terms of economy, but recently, it has been replaced with a capacitive type which has durability, sharpness and multi-touch capability in almost all devices.

The capacitive touch screen panel uses a capacitance in the body of a person to measure a change in resistance and current caused by a capacitance of a person using an AC voltage to recognize a touch, And a method of judging the presence or absence of touch by comparing the amount of charge. Such a capacitive touch screen panel has excellent durability as compared with a resistive film type using a film, so that it does not interfere with moisture or small damage. In addition, the accuracy of the touch is relatively high, and the optical characteristic is excellent and the screen is clear. In particular, the touch screen panel using the electrostatic capacity charging method is widely used in mobile smart devices because it can recognize multi points and can be manufactured in a small size.

However, the touch screen panel having the touch sensing function up to now does not support other functions other than the function of detecting the touch position which is the main object in the touch sensing method. Recently, various researches have been conducted to implement additional functions such as pressure sensing instead of simple touch position recognition. However, in order to implement pressure sensing in a touch screen panel, a separate pressure sensor must be separately provided on the touch screen panel The manufacturing cost is increased or the basic touch sensing function is deteriorated due to the change of the structure.

The present invention has been proposed in order to solve the above-mentioned problems of the previously proposed methods. The present invention relates to a touch screen panel in which a touch screen panel is bent due to a touch pressure applied on a touch screen panel, A TSP touch unit and a TSP sensor unit having a structure capable of sensing a pressure using a hole pattern formed in a region can be provided with a touch sensing function and a touch sensing function without having a separate pressure sensor on a touch screen panel configured for a touch sensing function. And to provide a pressure sensing device using the touch screen panel, which enables both sensing effects of the pressure sensing function to be realized and used.

In addition, the present invention can develop and construct a circuit including an IC chip in which functions of touch sensing and pressure sensing are realized without using a pressure sensor by combining a pressure sensor function with a curvature effect to a conventional touch sensor, It is another object of the present invention to provide a pressure sensing device using a touch screen panel, which can reduce the manufacturing cost by reducing the manufacturing cost of the touch screen panel and further improve the productivity by reducing the manufacturing cost of the touch screen panel.
