Touch sensor integrated display device

The invention relates to a touch sensor integrated display device.

In recent years, various flat panel display devices have been developed to meet the demand for displaying various types of multimedia. The development of flat panel display devices has been directed to achieving high screens, low manufacturing costs, and high quality such as high quality display moving images, high resolution, high brightness, high contrast, and wide color reproduction range. And various input devices such as a keyboard, a mouse, a trackball, a joystick, and a digitizer have been used to allow the user to respond to various display devices.

However, because the user needs to learn how to use each type of input device, the user may feel unsatisfied in use. And these input devices have problems occupying physical space. Therefore, there is an increasing demand for input devices that are capable of reducing operational errors and that are convenient and concise. In response to this increase in demand, a touch sensor has been proposed which allows a user to input desired information by directly touching the screen or approaching the screen by using his/her hand or pen while viewing the display device.

The touch sensor can have a simple configuration that can reduce operational errors. The user can also perform an input action without using a separate input device, and by viewing the content displayed on the screen, the touch device can be used to quickly and easily operate the display device. Therefore, such touch sensors have been applied to various display devices.

According to its structure, the touch sensor can be divided into an add-on touch sensor, an on-cell touch sensor, and an integrated (or inline (in) -cell) type touch sensor. The add-on touch sensor can be configured such that the display device and the touch panel including the touch sensor are separately manufactured, and then the touch panel can be adhered to the upper substrate of the display device. The on-cell touch sensor can be configured such that the touch sensor can be directly mounted on the surface of the upper glass substrate of the display device. Configurable integrated touch sensor enables touch sensor to be mounted in the display device Thereby, a thin profile of the display device is achieved and the durability of the display device is improved.

The in-cell touch sensor has the advantages of thin profile and improved durability because the common electrode of the display device is also used as the touch electrode of the touch sensor. Integrated touch sensors have become a focus of interest in the display industry due to these advantages over add-on and on-cell touch sensors.

The integrated touch sensor can be classified into a light type touch sensor and a capacitive touch sensor according to the method of sensing the touch position. The capacitive touch sensor can be further divided into a self-capacitance touch sensor and a mutual capacitance touch sensor.

The self-capacitive touch sensor may have a plurality of individual patterns in the touch area of the touch sensing panel, and measure a change in capacitance in each individual pattern, thereby detecting whether the touch operation is performed. On the other hand, the mutual-capacitive touch sensor may have an X-axis electrode string (eg, a drive electrode string) and a Y-axis electrode string that form a matrix with each other in the touch electrode region of the touch-sensing panel (eg, a sensing electrode string), applying a driving pulse to the X-axis electrode string, and sensing a voltage generated on the sensing node defined by the X-axis electrode string and the Y-axis electrode string crossing through the Y-axis electrode string Change to detect whether a touch operation is performed.

However, in the mutual capacitance touch sensor, the mutual capacitance between the X-axis electrode string and the Y-axis electrode string is very small, but is disposed in the display device by the gate line and the data line generated on the X-axis electrode string. The parasitic capacitance in the string of Y-axis electrodes is very large. Therefore, accurate recognition of the touch position is difficult.

In addition, the mutual capacitance touch sensor has a complicated routing line structure because the touch driving routing line is connected to the touch driving electrode string (for example, the X-axis electrode string), and because the touch sensing routing line is connected to the A touch sensing electrode string (for example, a Y-axis electrode string) of a multi-touch operation.

For these reasons, self-capacitive touch sensors having a simple structure with routing lines and high touch sensitivity have been widely used.

Hereinafter, a liquid crystal display (hereinafter referred to as a "touch sensor integrated display device") incorporating a self-capacitive touch sensor according to the prior art will be described with reference to FIG.

1 is a plan view of a touch sensor integrated display device according to the prior art.

As shown in FIG. 1 , the touch sensor integrated display device includes an active area AA in which a touch/common electrode is disposed and displays data, and a frame area BA disposed outside the active area AA. The bezel area BA has various routing lines including driving and sensing touch electrodes. An integrated circuit (IC) 10 for driving a source driver.

The active area AA includes a plurality of touch/common electrodes Tx11-Tx14, Tx21-Tx24, Tx31-Tx34, Tx41-Tx44, and Tx51-Tx54, and a plurality of touch routing lines TW11-TW14, TW21-TW24, TW31-TW34 , TW41-TW44, and TW51-TW54, the touch routing lines TW11-TW14, TW21-TW24, TW31-TW34, TW41-TW44, and TW51-TW54 are respectively connected to the plurality of touch/common electrodes Tx11-Tx14 , Tx21-Tx24, Tx31-Tx34, Tx41-Tx44, and Tx51-Tx54. The plurality of touch/common electrodes Tx11-Tx14, Tx21-Tx24, Tx31-Tx34, Tx41-Tx44, and Tx51-Tx54 are distributed in a first direction (for example, an x-axis direction) and a second direction (for example, intersecting each other). , y-axis direction). The plurality of touch/common electrodes Tx11-Tx14, Tx21-Tx24, Tx31-Tx34, Tx41-Tx44, and Tx51-Tx54 are disposed in parallel with each other along the second direction.

The plurality of touch electrodes Tx11-Tx14, Tx21-Tx24, Tx31-Tx34, Tx41-Tx44, and Tx51-Tx54 are formed by dividing a common electrode of the display device. The plurality of touch/common electrodes Tx11-Tx14, Tx21-Tx24, Tx31-Tx34, Tx41-Tx44 and Tx51 can function as a common electrode when displaying the display mode of the image data, and when detecting the touch mode of the touch position The role is the touch electrode.

The integrated circuit 10 in the bezel area BA supplies image data to the data line in synchronization with a gate line (not shown) that drives the display, and applies a common voltage to the touch/common electrodes Tx11-Tx14 in the display mode. , Tx21-Tx24, Tx31-Tx34, Tx41-Tx44 and Tx51. In addition, in the touch mode, the integrated circuit 10 applies a touch driving voltage to the touch/common electrodes Tx11-Tx14, Tx21-Tx24, Tx31-Tx34, Tx41-Tx44 and Tx51-Tx54, and is executed by The change of the touch/common electrode is scanned before and after the touch to detect the touch position.

The touch sensor integrated display device includes various lines, for example, routing lines TW11-TW14, TW21-TW24, TW31-TW34, TW 41-TW44, and TW51-TW54, and extends from the active area AA and is connected to the integrated circuit. 10 data line (not shown).

The routing lines TW11-TW14, TW 21-TW24, TW31-TW34, TW41-TW44 and TW51-TW54 are connected to the touch/common electrodes Tx11-Tx14, Tx21-Tx24, Tx31-Tx34 on a one-to-one basis. , Tx41-Tx44 and Tx51-TX54. As a result, as the size of the touch sensor integrated display device increases, the number of routing lines also increases because each routing line is connected to each touch/common electrode.

For example, when a touch sensor integrated display device having a size of 15.6 inches is constructed together with a touch/common electrode of 4.3 mm x 4.3 mm pitch size, 80 touch electrodes are disposed on the x-axis direction The upper and 45 common electrodes are placed in the y-axis direction, resulting in a total number of 3600 touch/common electrodes. In this case, 3600 touch/common electrodes are connected to the integrated circuit 10 through 3600 routing lines. These routing lines must be set to overlap the data lines to reduce the aperture ratio.

Therefore, when the routing lines are only disposed in one direction, the size of the touch/common electrodes should be amplified, or there may be some cases where the touch/common electrodes are not connected to the routing lines, thereby reducing the touch. Control sensitivity.

Accordingly, the present invention is directed to a touch sensor integrated display device and a method of fabricating the same, which substantially obviate the problems due to limitations and disadvantages of the related art.
