At present, display devices with all-metal back covers are popular among consumers because of the advantages of attractive appearance, high mechanical strength, good heat dissipation performance and the like. However, the display device with the all-metal back cover easily affects the signal transmission of the antenna, and the metal back cover easily shields the signal during the signal transmission of the antenna. In order to solve the signal shielding problem of the all-metal back cover, a slotting process is usually performed on a part of the metal back cover. However, the slitting process on the metal back cover may affect the appearance and local mechanical strength of the display device.
In view of the above, the embodiments of the present application provide a display panel and a display device, which can avoid the signal shielding problem of the metal back cover of the display device, and do not affect the appearance and mechanical strength of the display device.
In a first aspect of the embodiment of the present application, a display panel is provided, and fig. 1 is a schematic structural diagram of the display panel provided in the embodiment of the present application. As shown in fig. 1, the display panel includes: the antenna structure comprises a substrate layer 100, a display functional film layer 200 and an antenna structure 300, wherein the display functional film layer 200 is arranged on one side of the substrate layer 100; the antenna structure 300 is disposed on a side of the display function film layer 200 away from the substrate layer 100, and the antenna structure 300 includes metal grid lines. The display functional film layer 200 may be a pixel driving circuit layer, a color filter layer, and a liquid crystal layer of a liquid crystal display panel, and in an organic light emitting display panel, the display functional layer may also be an organic light emitting device layer, etc., which is not particularly limited in the embodiment of the present application. The side of the display functional film layer 200 is the display side of the display panel, and the antenna structure 300 is disposed on the display side of the display panel. The antenna structure 300 is disposed on the display side of the display panel, so that the antenna structure 300 can be prevented from being shielded by the signal of the metal back cover of the display device. The antenna structure 300 includes metal gridlines, and metal gridlines are the grid that has the fretwork, even adopt metal material, and metal gridlines possess certain light transmissivity, compare in the antenna structure of solid metal paster structure, antenna structure 300 that has metal gridlines has better light transmissivity, can avoid antenna structure 300 to influence the luminousness of realization panel, then antenna structure 300 sets up the display side at display panel and can not influence the display effect.
It should be noted that, in general, the metal back cover of the back display device with the antenna structure disposed on the display side of the display panel is mainly disposed on the back side of the display panel to provide strength support and housing protection, so that the antenna structure is located between the metal back cover and the display panel, and the metal back cover has a signal shielding effect due to the metal material of the metal back cover during the process of receiving or transmitting signals by the antenna structure, so that signal transmission of the antenna structure is greatly affected. To avoid signal shielding, a slot may be formed in the metal back cover plate to allow signals to be transmitted from the slot to the antenna structure, but the slot may affect the appearance and mechanical strength of the display device. Because the antenna structure is usually a metal material, the antenna structure is arranged on the display side of the display panel, and because the antenna structure is usually a solid metal patch and adopts a double-layer patch array, the light shielding effect is achieved, the light transmittance of the display panel can be influenced, and the display effect is influenced.
In view of the above problems, in the display panel provided by the embodiment of the application, the antenna structure 300 is disposed on the side of the display functional film layer 200 away from the substrate layer 100, i.e. the antenna structure 300 is disposed on the display side of the display panel, so that the problem that the antenna structure 300 is shielded by a signal of a metal back cover of the display device can be avoided. In addition, the antenna structure 300 includes metal grid lines, the metal grid lines are hollow grids, even if a metal material is adopted, the metal grid lines have certain light transmittance, compared with the antenna structure of a solid metal patch structure, the antenna structure 300 with the metal grid lines has better light transmittance, the effect that the antenna structure 300 affects the light transmittance of a panel can be avoided, and the antenna structure 300 is arranged on the display side of the display panel and cannot affect the display effect.
In some embodiments, the antenna structure includes at least two unit structures, the orthographic projections of different unit structures on the substrate layer are separated, which can be understood as that the orthographic projections of different unit structures on the substrate layer are not overlapped, that is, the unit structures are independent of each other, that is, the unit structures are also not connected, each unit structure is independently connected to a driving chip or a driving circuit of the antenna, and the independent unit structures can play a role in enhancing signal strength. The strength of the received and transmitted signals of a single unit structure is limited, and the strength of the received or transmitted signals can be improved by a plurality of unit structures. The unit structure comprises unit vibrators, and the unit vibrators are formed by metal grid lines. Under the condition of sending or receiving signals, the signals can cause excitation resonance of the unit vibrators, the excitation resonance of the unit vibrators can convert the signals into electromagnetic waves to be sent out, and the excitation resonance of the unit vibrators can convert the electromagnetic waves transmitted in the air into electric signals, so that the signals are received.
In some embodiments, the unit structure includes at least two unit vibrators, and the orthographic projection areas of the at least two unit vibrators of the same unit structure on the substrate layer are different. The area of the unit oscillator can determine the frequency band for receiving or transmitting signals, namely the resonance area of the unit oscillator can determine the frequency band of electromagnetic waves capable of inducing excitation resonance, and at least two unit oscillators with different areas are arranged in the same unit structure, so that the unit structure can cover a larger signal frequency band range, the antenna structure of the display panel can further cover a larger frequency band, and the application range is wider.

That is, the area of the first unit vibrator 310 is larger than the area of the second unit vibrator 320. Illustratively, the area ratio of the orthographic projections of the first unit cell 310 and the second unit cell 320 on the substrate layer 100 ranges from 1.3 to 1.4. The first unit vibrator 310 may cover a low frequency band, i.e., 24GHz to 27.5GHz, and the second unit vibrator 320 may cover a high frequency band, i.e., 26.5GHz to 29.5GHz.
The working frequency of the antenna structure of the display panel provided by the embodiment of the application is 24GHz to 29.5GHz, and N257 (26.5 GHz to 29.5 GHz) and N258 (24.25 GHz to 27.5 GHz) frequency bands are fully covered, and compared with the narrower working frequency band of the existing antenna structure, the antenna structure provided by the embodiment of the application has 5.5GHz ultra-wide working bandwidth. Meanwhile, the antenna has the in-band isolation characteristic of about 15dB, so that the anti-crosstalk performance in an antenna band is greatly improved, and the antenna also has the radiation gain characteristic of 1.11-3.07 dBi.

Referring to fig. 3, two ports P1 and P2 are led out from the middle position of the second connection line 332, and the lengths of the first outgoing lines 331 of the first unit vibrator 310 and the second unit vibrator 320 are the same, so that the signal transmission distances of the two ports P1 and P2 from each unit vibrator are the same, and the phase difference between the two unit vibrators is not required to be specially adjusted, the phase difference between the signals transmitted by the two ports P1 and P2 is the same, and the phase adjustment step can be omitted.

The display panel provided by the embodiment of the application is connected with the size patches which are arranged up and down in a series feed mode. By co-excitation of adjacent frequency bands, a relative bandwidth higher than 19.5% -10dB is achieved. By synthesizing two adjacent groups of excitation frequency bands, the broadband characteristic of a10 dB return loss reference (-10 dB relative bandwidth > 19.5%) of 24-29.5GHz is realized, and the main stream N257 and N258 frequency bands of the current 5G millimeter wave smart phone are fully covered. Meanwhile, the antenna provided by the application has a + -45 DEG dual polarization characteristic, and the signal receiving and transmitting strength of the on-screen integrated millimeter wave antenna is greatly improved.
In some embodiments, all the unit vibrators are arranged in the same layer.
