However, in the related art, due to the unreasonable setting of the installation position of the antenna on the electronic device, the development of the display panel towards a higher screen ratio is hindered. Based on the above problems, the embodiments of the present application provide a display panel and an electronic device, aiming to solve the above problems.

In a first aspect, an embodiment of the present application provides a display panel 100 . Referring to FIG. 1 , the display panel 100 includes a cover plate 110 , a display unit 120 and an antenna 130 . The display unit 120 is disposed on one side of the cover plate 110 , and the display unit 120 is provided with a non-display portion 121 for transmitting and/or receiving optical signals through the optical module 200 (see FIG. 2 ). The antenna 130 is disposed on the side of the cover plate 110 close to the display unit 120 and corresponds to the non-display portion 121 .

A display panel 100 according to the embodiment of the present application, in combination with the electronic device 1, further includes an optical module 200 for transmitting and/or receiving optical signals, and in order to enable the optical module 200 to work normally, the display unit 120 is provided with a The characteristic of the non-display part 121 corresponding to the optical module 200 is that the antenna 130 is set to correspond to the non-display part 121 , so that for the display unit 120 and the antenna 130 , the electronic device 1 only needs to reserve installation space for the display unit 120 In this way, the installation of the display unit 120 and the antenna 130 can be realized, so that the arrangement of the antenna 130 will not hinder the development of the display panel 100 towards a higher screen ratio.

The non-display portion 121 is a portion of the display unit 120 that does not display image and/or screen information when the display panel 100 operates. Referring to FIG. 2 , the display unit 120 further includes a display part 122 , and the display part 122 is a part of the display unit 120 for displaying images and/or screen information when the display panel 100 is working. The non-display part 121 and the display part 122 of the display unit 120 can be divided according to the size of the optical module 200; for example, the non-display part 121 can satisfy: the orthographic projection of the optical module 200 on the display unit 120 is located in the non-display part 121 , and the display part 122 may be other parts of the display unit 120 other than the display part 121 . Preferably, the non-display portion 121 may satisfy that the boundary line of the non-display portion 121 coincides with the boundary line of the orthographic projection of the optical module 200 on the display unit 120 .

The optical module 200 may be any device that transmits and/or receives optical signals transmitted through the non-display portion 121 . For example, the optical module 200 may be a camera module, an infrared sensor, or the like. In order to make the area of the non-display portion 121 as small as possible, the non-display portion 121 can also satisfy the requirement that the light entrance hole and/or the light exit hole of the optical module 200 are located in the non-display portion 121 in the orthographic projection of the display unit 120 . .

The non-display portion 121 of the display unit 120 is not provided with a display function layer, so that when the display panel 100 is operating, the non-display portion 121 does not display image and/or screen information. The non-display part 121 of the display unit 120 is not provided with a display function layer, which may be: the non-display part 121 is not filled with liquid crystal and has no metal layer (signal wiring layer, electrode layer, etc.). area. Of course, in order to ensure the quality of light emitted and/or received by the optical module 200, referring to FIG. 3 and FIG. 4, the non-display portion 121 may be provided with a through hole 123, and the through hole 123 is used for transmitting and/or transmitting through the optical module 200 and/or received optical signal. The boundary line of the through hole 123 may be located inside the boundary line of the non-display portion 121 , and the boundary line of the through hole 123 may also overlap with the boundary line of the non-display portion 121 .

The antenna 130 is disposed on the side of the cover plate 110 close to the display unit 120, the antenna 130 may be disposed between the cover plate 110 and the display unit 120, see FIG. 3; the antenna 130 may also be disposed on the display unit 120 away from the cover plate 110. side, see Figure 4. When the antenna 130 is disposed on the side of the display unit 120 away from the cover plate 110, there is preferably no conductive device between the antenna 130 and the cover plate 110, so as to avoid the conductive device from affecting the direction of the antenna 130 to the side of the cover plate 110 away from the display unit 120. Radiation performance. Of course, in order to ensure the radiation efficiency of the antenna 130 , the antenna 130 is preferably disposed between the cover plate 110 and the display unit 120 .

When the antenna 130 is disposed between the cover plate 110 and the display unit 120 , in order to ensure the radiation efficiency of the antenna 130 , referring to FIGS. 2 and 3 , the antenna 130 is preferably connected to the surface of the cover plate 110 adjacent to the display unit 120 . The implementation of the connection between the antenna 130 and the surface of the cover plate 110 adjacent to the display unit 120 may be as follows: the antenna 130 is directly formed on the surface of the cover plate 110 adjacent to the display unit 120 . The implementation of the connection between the antenna 130 and the surface of the cover plate 110 adjacent to the display unit 120 can also be as follows: the antenna 130 is formed on other transparent substrates 140, and the transparent substrate 140 is connected to the surface of the cover plate 110 adjacent to the display unit 120. See Figure 5. In order to simplify the setting of the antenna 130 and prevent the antenna 130 from occupying the internal space of the electronic device 1, the antenna 130 may be formed by a process such as printing.

The preparation material of the antenna 130 can be any conductive material. For example, the preparation material of the antenna 130 may include indium tin oxide or nano-silver. When the antenna 130 is made of an opaque conductive material, the influence of the antenna 130 on the operation of the optical module 200 can be reduced by adjusting the length and width of the antenna 130 . Besides, the preparation material of the antenna 130 may also be a light-transmitting conductive material.

The cover plate 110 can be made of any light-transmitting material. The light-transmitting material may be light-transmitting glass or the like. Transparent optical glue may be used for bonding between the cover plate 110 and the transparent substrate 140 , between the cover plate 110 and the display unit 120 or between the transparent substrate 140 and the display unit 120 . The transparent optical adhesive may be OCA (Optically Clear Adhesive) optical adhesive. The light transmittance of the OCA optical adhesive is as high as 90%, the light transmission effect is good, and the volume of the OCA optical adhesive after curing is small, which is convenient for realizing the thinning of the display panel 100 .

In order to realize the radiation of the antenna 130 , referring to FIG. 6 , the display panel 100 further includes a radio frequency transceiver 150 and an electrical connector 160 . The radio frequency transceiver 150 is disposed on the side of the display unit 120 away from the cover plate 110 . One end of the electrical connector 160 is electrically connected to the antenna 130 , and the other end of the electrical connector 160 is electrically connected to the radio frequency transceiver 150 . The electrical connector 160 includes a first portion 161 corresponding to the non-display portion 121 . The preparation material of the first part 161 can be any conductive material. When the preparation material of the first part 161 is an opaque conductive material, the influence of the first part 161 on the operation of the optical module 200 can be reduced by adjusting the length and width of the first part 161 . Certainly, in order to reduce the influence of the first part 161 on the operation of the optical module 200 , the preparation material of the first part 161 may be a light-transmitting conductive material.

The number of antennas 130 may be arbitrary. Certainly, in order to expand the radiation area of the antenna 130 and improve the radiation performance of the antenna 130 , referring to FIG. 7 , the number of the antennas 130 may be multiple. The plurality of antennas 130 may be randomly arranged. In order to equalize the distribution of the signals radiated by the antennas 130, referring to FIG. 7, the multiple antennas 130 may also be arranged in an array.

The antenna 130 may be any antenna. For example, the antenna 130 may be a millimeter-wave antenna, a microwave antenna, or the like. Since the size of the surface of the optical module 200 facing the cover plate 110 and the size of the non-display portion 121 are designed to be relatively small when the high screen ratio of the electronic device 1 is achieved, generally at the level of several millimeters, which is different from that of the millimeter wave. The wavelengths are close, therefore, to ensure the radiation performance of the antenna 130, the antenna 130 may be a millimeter-wave antenna.

Millimeter wave refers to electromagnetic waves with a wavelength range of 1 mm to 10 mm. Its wavelength range is in the area where microwaves and far-infrared waves overlap, so it has the characteristics of both microwave and far-infrared waves. Millimeter waves have a large number of applications in communications, radar, remote sensing, and site astronomy. On the electronic device 1, millimeter wave technology can realize gesture recognition; respiration monitoring; heart rate monitoring; gesture operation to start and stop music, switch music, adjust volume; or measure heart rate and respiration in the air. Millimeter wave technology is an effective means to realize human-computer interaction, and has excellent performances such as high precision, real-time performance and wide detection range.

Millimeter waves have a certain penetration ability to conductive materials (such as ITO, metal, etc.) below tens of nanometers, and the penetration rate of conductive materials higher than tens of nanometers is very low, and millimeter waves penetrate conductive materials. The ability of the material is poor, and the conductive film layers used in electronic devices such as the display unit 120, such as the TP sensor and the Array driver circuit, have a thickness of several microns, and the millimeter wave cannot penetrate well. For this reason, the millimeter wave The antenna is generally installed in an area other than the display unit 120 in the electronic device 1, which hinders the development of the display panel 100 towards a higher screen ratio. In the embodiment of the present application, by disposing the antenna 130 on the non-display portion 121 and on the surface of the cover plate 110 adjacent to the display unit 120 , it not only does not hinder the development of the display panel 100 to a higher screen ratio, but also because the cover plate 110 is on the surface of the display unit 120 . There is no conductive material, and the penetration of millimeter waves can also be ensured, so that the antenna 130 can exert better radiation performance.

In a second aspect, an embodiment of the present application provides an electronic device 10 . Referring to FIGS. 2 to 4 , the electronic device 10 includes a display panel 100 and an optical module 200 . The electronic device 10 may be any device having a display function and a function of transmitting and/or receiving optical signals. For example, the electronic device 10 may be a smart phone, a wearable device, a computer device, a television, a vehicle, a camera, a monitoring device, and the like.

The optical module 200 is located on the side of the display unit 120 away from the cover plate 110 , and the optical module 200 corresponds to the non-display portion 121 . The optical module 200 may be any device that transmits and/or receives optical signals transmitted through the non-display portion 121 . For example, the optical module 200 may be a camera module, an infrared sensor, or the like.

To avoid wear of the optical module 200 and/or the display panel 100 when the optical module 200 and the display panel 100 move relative to each other, a gap may be left between the optical module 200 and the display panel 100 .
