[0002] Today, Internet technology is booming, and Internet applications are inseparable from modern people's lives. For example, people use electronic devices to connect to the Internet to receive news information, contact relatives and friends, and record their lives. In order to meet users' demand for portable electronic devices, the way to connect to the Internet has evolved from fixed network cables to wireless Internet access. Whether it is a laptop, personal digital assistant or smart phone, it is equipped with wireless Internet access.

[0003] Generally speaking, portable electronic devices are equipped with antennas to send and receive signals, and can access the Internet wirelessly. For example, manufacturers will install multiple antennas on both sides of a laptop screen. In addition to being able to use the antennas to send and receive signals for wireless Internet access, the antennas will also prevent interference with the electronic components inside the laptop host. In order to increase the bandwidth of the antenna's signal transmission and reception, manufacturers will add additional antennas to match the required bandwidth. However, the space on both sides of the current laptop screen is already equipped with antennas and is not enough to install additional antennas. If additional antennas are to be installed to match a wider frequency band, additional designs must be made to the laptop casing, such as additional assembly components, which will increase the manufacturing cost of the laptop. Therefore, how to balance the requirements of antenna signal bandwidth and reduce the cost of installing additional antennas on laptops is one of the problems that R&D personnel should solve.

[0047] See also Figures 1 to 3 . Figure 1 FIG. 4 is a schematic three-dimensional diagram of a display device according to an embodiment of the present invention. Figure 2 for Figure 1 A partially enlarged three-dimensional schematic diagram of a display device. Figure 3 for Figure 1 A plan view of a display device.

[0048] The display device 10 of this embodiment includes a housing 20, a display screen 30 and a lens module 40. The housing 20 includes a bottom plate 21, two side plates 22 and a top plate 23. The two opposite sides of the two side plates 22 are respectively connected to the bottom plate 21 and the top plate 23, and the bottom plate 21, the two side plates 22 and the top plate 23 surround a receiving space S. The display screen 30 is located in the receiving space S. The lens module 40 is located in the receiving space S and is disposed between the display screen 30 and the top plate 23. In other words, the lens module 40 is disposed in the space on the top of the display screen 30.

[0049] The lens module 40 includes a flexible circuit board 41, a lens 42, and an antenna assembly 43. The flexible circuit board 41 includes a flexible substrate 411 and a ground structure 412. The ground structure 412 is disposed on the flexible substrate 411. The lens 42 is disposed on the flexible substrate 411. The antenna assembly 43 is disposed on the flexible substrate 411 and is electrically connected to the ground structure 412. The antenna assembly 43 is disposed between the lens 42 and the top plate 23. In other words, by integrating the antenna assembly 43 into the flexible circuit board 41 of the lens module 40, the antenna assembly 43 is disposed in the space at the top of the lens 42.

[0050] The antenna assembly 43 includes a first antenna unit 431, a second antenna unit 432, and a third antenna unit 433. The second antenna unit 432 and the third antenna unit 433 are symmetrically located on opposite sides of the first antenna unit 431. The first antenna unit 431 includes a connecting portion 4311 and an extending portion 4312. One side of the connecting portion 4311 is electrically connected to the ground structure 412. The other side of the connecting portion 4311 is connected to the middle section of the extending portion 4312, and the connecting portion 4311 is perpendicular to the extending portion 4312, so that the first antenna unit 431 is T-shaped and can match the 1.7 GHz frequency band.

[0051] The second antenna unit 432 and the third antenna unit 433 each include a straight line portion 4321, 4331, a first protruding portion 4322, 4332, and a second protruding portion 4323, 4333. The first protruding portions 4322, 4332 protrude and are perpendicular to the straight line portions 4321, 4331, respectively, and the second protruding portions 4323, 4333 protrude and are perpendicular to the straight line portions 4321, 4331, respectively, and the second protruding portion 4323 is closer to the connecting portion 4311 than the first protruding portion 4322, so that the second antenna unit 432 and the third antenna unit 433 are in an inverted F shape and can match the frequency band of 3 GHz to 5 GHz. In addition, since the lengths L1 and L2 of the first protrusions 4322 and 4332 and the lengths L3 and L4 of the second protrusions 4323 and 4333 are smaller than the length L5 of the connecting portion 4311 , at least part of the straight portion 4321 of the second antenna unit 432 and the third antenna unit 433 is located between the extending portion 4312 and the lens 42 .

[0052] In this embodiment, since the space on the two opposite sides of the display screen 30 is insufficient to additionally set up the antenna assembly 43, the antenna assembly 43 can be integrated into the flexible circuit board 41 of the lens module 40, so that the space on the top of the lens 42 can be used to additionally set up the antenna assembly 43 to match the bandwidth required by the user. In this way, in addition to meeting the user's demand for the antenna signal bandwidth, the existing space on the top of the lens 42 can also be used to set up the antenna assembly 43 without additional assembly components, thereby reducing the cost of additionally installing the antenna assembly 43 on the display screen 30.

[0053] In this embodiment, the display device 10 may further include two cables 50. The two cables 50 are electrically connected to the second protrusion 4323 of the second antenna unit 432 and the second protrusion 4323 of the third antenna unit 433, respectively, so that a power supply device (not shown) of the display device 10 can provide power to the second antenna unit 432 and the third antenna unit 433 through the two cables 50.

[0054] According to the display device and lens module of the above-mentioned embodiment, since the antenna component is integrated into the flexible circuit board of the lens module, the antenna component can be set between the lens and the top plate, that is, the space on the top of the lens is used to additionally set the antenna component to match the bandwidth required by the user. Therefore, in addition to meeting the user's demand for the antenna signal bandwidth, the existing space on the top of the lens can also be used to set the antenna component without the need for additional assembly components, thereby reducing the cost of additionally installing the antenna component on the display device.

[0055] Although the present invention is disclosed as above with the aforementioned embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the patent protection scope of the present invention shall be determined by the claims attached to this specification.
