Description

TECHNICAL FIELD [0001] The present invention relates to a touch sensor integrated type display device,

The present invention relates to a touch sensor integrated type display device, and more particularly, to a touch sensor integrated type display device capable of improving touch sensitivity while reducing the number of touch routing lines.

In recent years, there has been a demand for display devices that can be enlarged in size, cost is low, and display quality (video expression power, resolution, brightness, contrast ratio, color reproduction power, etc.) (Hereinafter simply referred to as "display device") has been developed. In these flat display devices, various input devices such as a keyboard, a mouse, a trackball, a joystick, and a digitizer are used to configure an interface between a user and a display device.

However, the use of the above-described input device has a drawback in that it is required to learn how to use it and occupies a space, thereby making it difficult to improve the completeness of the product. Accordingly, there is a growing demand for an input device for a display device that is convenient and simple and can reduce malfunctions. In response to such a request, a touch sensor has been proposed that allows a user to directly touch the screen with a hand or a pen or the like while looking at the display device, and to recognize information when the information is input.

The touch sensor is simple, has little malfunction, can be input without using a separate input device, and is also applicable to various display devices because of convenience that the user can quickly and easily operate the contents displayed on the screen have.

The touch sensor used in the above-described display device can be divided into an add-on type, an on-cell type, and an integrated type or an in-cell type according to its structure. In the top plate attaching type, the touch sensor module is attached to the upper plate of the display device after separately manufacturing the display device and the touch sensor module. The built-in top plate is a method of directly forming the touch sensor elements on the upper glass substrate surface of the display device. The built-in type incorporates touch sensor elements in the display device to achieve a thin display device and enhance durability.

Among them, the built-in touch sensor can commonly use a common electrode of a display device as a touch and a common electrode, so that a thickness thereof can be reduced, and a touch element is formed inside the display device, thereby enhancing durability.

Accordingly, the built-in touch sensor has been attracting attention because it can solve the disadvantages of the top mount type touch sensor and the top plate built-in touch sensor in that the durability can be improved and the thickness can be reduced. The built-in touch sensor is divided into an optical type and a capacitive type according to a method of sensing a touched portion, and the electrostatic type is subdivided into a self capacitance type and a mutual capacitance type. do.

The self-capacitance type touch sensor forms a plurality of independent patterns in the touch area of the touch sensing panel and measures the change of the capacitance of each independent pattern to determine whether or not the touch is detected. The mutual capacitance type touch sensor includes X-axis electrode lines (for example, driving electrode lines) and Y-axis electrode lines (for example, sensing electrode lines) in a touch and common electrode formation region of the touch sensing panel Axis, and a driving pulse is applied to the X-axis electrode lines. Then, a voltage change in the sensing nodes defined as the intersections of the X-axis electrode lines and the Y-axis electrode lines through the Y-axis electrode lines And determines whether or not the touch is detected.

However, mutual capacitance type touch sensor has a very small magnitude of mutual capacitance between X-axis electrode lines and Y-axis electrode line generated when a touch is recognized. On the other hand, the X- The parasitic capacitance formed in the electrode lines and the Y-axis electrode line is very large, which makes it difficult to accurately recognize the touch position by the parasitic capacitance.

In addition, since the mutual capacitance type touch sensor requires a plurality of touch driving lines for touch driving and a plurality of touch sensing lines for touch sensing on the common electrode for multitouch recognition, a very complicated wiring structure is required .

The self-capacitance type touch sensor has a wider wiring structure than the mutual capacitance type touch sensor and can be used to increase the touch accuracy.

Hereinafter, a conventional liquid crystal display device with a built-in self-capacitance type touch sensor (hereinafter simply referred to as a "touch sensor integrated type display device") will be described with reference to Fig. 1 is a plan view showing a conventional touch sensor integrated type display device.

Referring to FIG. 1, a touch sensor integrated type display device includes touch and common electrodes, and includes an active area AA for displaying data, various wirings disposed outside the active area AA, including routing wirings, And a bezel area BA on which the touch sensing IC 10 is formed.

The active area AA includes a plurality of touch and common electrodes Tx11 to Tx14 and Tx21 that are divided in a first direction (for example, an x-axis direction) and a second direction (for example, And the plurality of touch and common electrodes Tx11 to Tx14, Tx21 to Tx24, Tx31 to Tx34, Tx41 to Tx44, and Tx51 to T54 are respectively connected to the plurality of touch and common electrodes Tx11 to Tx24, Tx31 to Tx34, Tx41 to Tx44 and Tx51 to Tx54, (TW11 to TW14, TW21 to TW24, TW31 to TW34, TW41 to TW44, TW51 to TW54) arranged in parallel to each other in two directions.

The plurality of touch and common electrodes Tx11 to Tx14, Tx21 to Tx24, Tx31 to Tx34, Tx41 to Tx44 and Tx51 to T54 in the active area AA are formed by dividing the common electrode of the display device, The display mode operates as a common electrode while the touch mode for recognizing the touch position operates as a touch electrode.

The source driver and the touch driver IC 10 for a display device disposed in the bezel area BA are connected to data lines (not shown) in synchronization with the driving of the gate lines (not shown) And supplies a common voltage to the touch and common electrodes Tx11 to Tx14, Tx21 to Tx24, Tx31 to Tx34, Tx41 to Tx44, and Tx51 to T54. The source driving and touch driving IC 10 also supplies a touch driving voltage to the touch and common electrodes at the time of touch operation and scans a change in capacitance of the touch and the common electrode before and after the touch, The position of the electrode is determined.

The various wirings are connected to the touch and common electrodes Tx11 to Tx14, Tx21 to Tx24, Tx31 to Tx34, Tx41 to Tx44 and Tx51 to T54, extend from the active area AA, (Not shown), and routing wires (TW11 to TW14, TW21 to TW24, TW31 to TW34, TW41 to TW44, TW51 to TW54) and data wires (not shown) connected thereto.

Are arranged in one direction (y-axis direction in the example of FIG. 1) through the wirings and are individually connected to the source driving and touch-driving IC 10. In this case, the larger the size of the display device, the larger the number of routing wirings connected to each touch and common electrode, and the routing wirings must be arranged so as to overlap with the data lines in order to prevent the aperture ratio from decreasing.

Therefore, when the routing wiring is arranged in only one direction, the size of the touch and common electrode may be increased or the routing wiring may not be connected to some touch and common electrodes. This causes a problem of lowering the touch sensitivity.
