ELECTRONIC DEVICE HAVING BEZELESS TOUCH SCREEN AND DISPLAY BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an electronic device having a bezelless touch screen and a display, and more particularly to a bezelless touch screen having a wider display area and being easy to assemble and disassemble, and an electronic device equipped with a display.

2. Description of the Related Art Generally, a touch screen panel is a device for inputting a command of a user by touching a character or a figure displayed on a screen of a display unit with a finger or other contact means of a person, and is attached and used on a display unit. The touch screen panel converts a contact position that is touched by a human finger or the like into an electrical signal, and the electrical signal is used as an input signal.

The touch screen panel includes a plurality of sensor pads formed on a substrate and a plurality of signal wirings connected to the sensor pads. The touch signal input to the sensor pad is transmitted to a driving device for driving the touch screen through a plurality of signal lines and can be used as an input signal.

FIG. 1 is a plan view showing a conventional mobile electronic device, FIG. 2 is a cross-sectional view illustrating an example of connection of components of a conventional mobile electronic device, and FIG. 3 is a schematic view of a conventional capacitive touch device Fig. 8 is an exploded view showing an example of a screen panel. Fig.

1 to 3, a mobile electronic device 10 according to the related art includes a main board 20, a display unit 30, a touch screen panel 40, A cover glass 50, and a housing 60.

The main board 20 is provided with electronic parts required for driving the mobile electronic device 10. The main body 20 includes a main board 20, a display unit 30, a touch screen panel 40, The glass 50 is engaged and fixed.

The touch screen panel 40 includes a first sensor pattern layer 42, a first insulating layer 43, a second sensor pattern layer 44, and a second sensor pattern layer 43 formed on the transparent substrate 41 and the transparent substrate 41, 2 insulating film layer 45 and a metal wiring 46.

The first sensor pattern layer 42 may be laterally connected to the transparent substrate 41 and connected to the metal wiring 46 on a row-by-row basis.

The second sensor pattern layer 44 may be connected to the first insulating layer 43 along the longitudinal direction and alternately arranged with the first sensor pattern layer 42 so as not to overlap the first sensor pattern layer 42 . Further, the second sensor pattern layer 44 is connected to the metal wiring 46 on a thermal unit basis.

The metal wiring 46 is formed on the outer surface of the touch screen panel 40 and transmits an electrical signal corresponding to the touch contact position. That is, when a finger or contact means of a human touches the touch screen panel 40, a drive circuit (not shown) is connected to the first sensor pattern layer 42, the second sensor pattern layer 44, A change in capacitance according to the contact position is transmitted. Then, the contact position is determined as the change in capacitance transferred is converted into an electrical signal.

Since the metal wiring 46 covers the image of the display unit 30, the metal wiring 46 is arranged outside the display unit 30 by making the touch screen panel 40 larger than the display unit 30 Respectively.

The bezel for preventing the metal wiring from being exposed to the outside when the touch screen panel 40 is mounted on a mobile electronic device is called a ' A 'region. The bezel is generally formed by applying a colored ink, for example, a black ink, in order to cover the wiring. Therefore, in a conventional mobile electronic device, it is difficult to realize a display area without a bezel exposed to the outside or a narrow display area. In consideration of the metal wiring of the display unit 30, the bezel area A has to be larger. However, such a bezel not only causes a problem of reducing the size of the display area displayed in the mobile electronic device of the same size, but also reduces the aesthetic sensitivity of the display portion of the mobile electronic device 10 as a whole.

On the other hand, even if disposition of the metal wiring of the touch screen panel 40 is neglected, the bezel has to be formed broadly due to the bonding portion between the touch screen panel 40 and the housing 60. That is, the touch screen panel 40 is coupled to the upper surface of the step portion 61 formed at the lower portion of the housing 60 by thermally welding using a tape type or epoxy. In such a tape type or heat fusion type method, the bonding force is determined depending on the area of the bonding site. In order for the touch screen panel 40 and the housing 60 to have the required level of bonding strength, a bonding area of an area similar to or larger than the bezel area was required. Further, since the touch screen panel 40 and the housing 60, which are coupled by the tape method or the heat welding method, can not be separated after bonding, defects may occur in the assembling process, It is not easy to replace and repair the parts at the time of repair, which causes a problem of increase in replacement cost and labor cost.

Meanwhile, in recent years, a display unit and a touch screen panel are mechanically inserted into a housing in consideration of mold-type integration. However, a bezel region for covering a metal wiring region existing in a touch screen panel or a display unit There is a problem.
