Description

Display panel and display device Technical Field The present application relates to the field of communications technologies, and in particular, to a display panel and a display device. Background The spectrum of 5G (fifth generation mobile communication) includes millimeter Wave (millimeter-Wave, i.e., mm-Wave) and non-millimeter Wave (non-mm-Wave) bands. The millimeter wave band has a higher channel capacity (CHANNEL CAPACITY) because of its wider bandwidth than the non-millimeter wave band, so that millimeter wave energy can be used for faster data transmission, thereby meeting the higher information rate requirements of users. However, millimeter wave antennas are often designed in an antenna array (consisting of more than two antenna units) due to their high propagation loss and high sensitivity to shielding, the number of antennas in 5G mobile phones is more than that of antennas before 4G and 4G, the screen duty ratio of the display panel is also higher and higher, and the placement of the antennas on the display panel becomes a major factor for restricting the communication performance of the display device. Disclosure of Invention The application mainly solves the technical problem of providing a display panel and a display device, wherein the second antenna is used for separating the first antennas, so that the isolation between the first antennas is increased. In order to solve the technical problems, the technical scheme includes that the display panel comprises a light-emitting layer, a plurality of first antennas and a second antenna, wherein the first antennas are positioned on one side of a light-emitting surface of the light-emitting layer and are mutually spaced, the second antennas are positioned on one side of the light-emitting surface of the light-emitting layer, and each second antenna comprises a separation part extending through a separation area between two adjacent first antennas. In order to solve the technical problems, the application adopts another technical scheme that the display device comprises the display panel. The display panel has the beneficial effects that the display panel comprises a light-emitting layer, a plurality of first antennas and a plurality of second antennas, which are different from the prior art. The first antennas are positioned on one side of the light emitting surface of the light emitting layer and are arranged at intervals, and the second antennas are positioned on one side of the light emitting surface of the light emitting layer and comprise isolation parts which extend through interval areas between two adjacent first antennas. By means of the mode, the first antennas are arranged on the display area formed by the light-emitting layers, so that the influence of the introduction of the first antennas on the screen duty ratio is reduced, the full screen is facilitated, and further, the second antennas are utilized to separate the first antennas, and the isolation degree between the first antennas is increased.
