Patent Description:
Wireless communication technologies have recently been implemented in various manners, such as a wireless local area network (WLAN) represented by a wireless fidelity (Wi-Fi) technology, Bluetooth, near field communication (NFC), etc., as well as commercialized mobile communication network access. Mobile communication services have evolved from voice call based first-generation mobile communication services into fourth-generation mobile communication networks, thereby making utilization of the Internet and multimedia services on a mobile communication terminal possible. Next-generation mobile communication services, which will be commercialized in the future, are expected to be provided through an ultra-high frequency band of tens of gigahertz (GHz) or more. For example, the majority of mobile communication terminals that implement the long term evolution (LTE) technology by the 3GPP standard, which has been widely used as a representative of the fourth-generation (<NUM>) mobile communication all over the world, must basically support a band of <NUM> megahertz (MHz) to <NUM> and a band of <NUM> to <NUM>.

Further, with the activation of communication standards (such as WLAN, Bluetooth, etc.), electronic devices, for example, mobile communication terminals, have been equipped with antenna devices that operate in different frequency bands. For example, fourth-generation mobile communication services may operate in a frequency band of <NUM>, <NUM>, <NUM>, etc.; Wi-Fi may operate in a frequency band of <NUM> and <NUM> but with a slight difference depending on the standard implemented; and Bluetooth may operate in a frequency band of <NUM>.

Electronic devices require antenna devices in order to make wireless communication possible. The antenna devices are installed with a sufficient distance from other devices to prevent the antenna devices from interfering with the other devices when transmitting and receiving high frequency signals.

These antenna devices are required to have excellent radiation performance and a wide band width even within a small volume in order to conform to the design trend of electronic devices that is moving toward slimness and compactness. For example, as antenna areas where internal antenna devices may be embedded in electronic devices have become narrower, it is an important issue in antenna design to obtain excellent radiation performance without varying the sizes of the antenna devices.

Further conventional display devices are disclosed in <CIT>, <CIT>, <CIT>, <CIT> and <CIT>.

In cases where antenna devices are embedded in touch panels of electronic devices, the electronic devices may be made compact by reducing the spaces where the antenna devices are mounted in the electronic devices, but the touch functions of the touch panels and the radiation performance of the antenna devices may degrade.

Further, in the cases where antenna devices are embedded in display devices of electronic devices, the antenna devices may interfere with the movement of light within the display devices, thereby deteriorating the quality of the display devices.

The display device, according to the various embodiments of the present disclosure, has the conductors arranged between the pixels so that it is possible to prevent the conductors from interfering with light that travels through the pixels. Further, since the conductors are arranged between the pixels, it is possible to reduce a separate space for mounting an antenna radiator, which is constituted by conductors, in an electronic device, thereby making the electronic device compact. In addition, since the conductors are arranged between the pixels, it is possible to prevent a degradation in the touch function of the display device that has a touch panel.

The above and other aspects, features, and advantages of the present disclosure will be more apparent from the following detailed description, taken in conjunction with the accompanying drawings, in which:.

In contrast, it may be understood that when an element (e.g., a first element) is referred to as being "directly connected," or "directly coupled" to another element (e.g., a second element), there is no element (e.g., a third element) interposed therebetween.
