Liquid crystal display device with antenna

The present invention relates to a liquid crystal display device, and more particularly to a liquid crystal display device having an antenna.

An antenna is an indispensable component for transmitting wireless signals. Any electronic device that needs to transmit wireless signals (such as a smart phone or PDA) has an antenna.

The antenna of the prior art is disposed on the frame or other position of the screen of the electronic device, and the area of the frame is usually small, so the antenna always needs to be miniaturized, which will have the disadvantages of poor sensing and inductive action. .

For example, Taiwan Patent Publication No. M407498 discloses an antenna module and a touch module and an electronic device using the same. The antenna module includes a transparent substrate and an antenna assembly disposed on the transparent substrate. The antenna assembly includes a radiation portion. The feeding portion and the ground portion are located at corners of the transparent substrate, and the ground portion includes a first strip portion and a second strip portion that are integrally connected to each other. The antenna of Taiwan Patent Publication No. M407498 is disposed at the frame or other position of the screen of the electronic device, and thus has the disadvantage that the above-described induction is poor and the sensing action is not user-friendly.

For example, Taiwan Patent Publication No. I345333 discloses a modular antenna structure, comprising: a first antenna module for receiving a first transmission signal, at least one side of which includes a first opening; and a second The antenna module is configured to receive a second transmission signal, and at least one side thereof further includes a second opening; and a fixing component; the first antenna module and the second component are assembled The antenna module partially overlaps and overlaps the first opening and the second opening, and then the fixing component passes through the first opening and the second opening and is held on the screen of an electronic device. The antenna of Taiwan Patent Publication No. I345333 is disposed at the frame or other position of the screen of the electronic device, and thus has the disadvantage that the above-described induction is poor and the sensing action is not user-friendly.

For example, Taiwan Patent Publication No. M368256 discloses a notebook computer screen support structure in which an antenna is embedded, which embeds a plurality of antennas of different operating frequency bands in the front edge of the upper bracket, and installs most of the ground in the upper bracket. The circuit board is such that the feed end of each antenna is connected to the circuit board, and the antenna transceiver signal is transmitted to the motherboard by using a cable connected to the main board of the notebook computer on each circuit board. The antenna of Taiwan Patent Publication No. M368256 is disposed at the frame or other position of the screen of the electronic device, and thus has the disadvantage that the above-described induction is poor and the sensing action is not user-friendly.

In summary, the antennas of the prior art are disposed on the frame or other positions of the screen of the electronic device, and thus have the disadvantages of poor sensing and inductive sensing.

In order to improve the above disadvantages of the prior art, it is an object of the present invention to provide a liquid crystal display device having an antenna.

In order to achieve the above object of the present invention, the liquid crystal display device with antenna of the present invention comprises an antenna unit, a liquid crystal display backlight source unit and a liquid crystal display unit.

Furthermore, the liquid crystal display device with an antenna further comprises a absorbing material unit and a metal unit. The absorbing material unit is disposed under the antenna unit; the metal unit is disposed under the absorbing material unit. Wherein, the liquid crystal display unit comprises a lower side glass substrate, a liquid crystal unit and an upper side glass substrate. The lower side glass substrate is disposed on the liquid crystal display backlight source unit; the liquid crystal unit is disposed on the lower side glass substrate; and the upper side glass substrate is disposed on the liquid crystal unit.

The function of the liquid crystal display device with the antenna of the present invention is that the external portable electronic device can easily complete the transmission of the radio signal with the antenna unit by being close to the liquid crystal display unit, and the user motion is natural and smooth, and convenient. Unlike conventional antennas, which are placed on the border of the screen or other locations, there is a disadvantage that the sensing is not good and the sensing action is not user-friendly.
