Detailed Description
For the purposes of promoting an understanding of the principles and advantages of the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same.
It should be noted that unless otherwise defined, technical or scientific terms used in the embodiments of the present disclosure should be given the ordinary meaning as understood by one of ordinary skill in the art to which the present disclosure pertains. The terms "first," "second," and the like, as used in embodiments of the present disclosure, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed. The Tx layer is sometimes referred to as Tx electrode and the Rx layer is also referred to as Rx electrode.
An integrated touch function (TP) design is often adopted in an OLED (Organic Light-Emitting Diode) display panel, that is, a touch layer (TP) is integrated in the display panel, for example, the touch layer is disposed on an encapsulation layer. In the case of the touch layer design, it includes Tx and Rx electrodes, and the Tx and Rx electrodes are separately designed, i.e., the Tx and Rx electrodes are not in the same layer. If the millimeter wave antenna array (also referred to as millimeter wave antenna) is integrated under the structure, an ITO (Indium tin oxide) film layer exists under the position where the radiation unit of the antenna is located (projection to the package layer side), and a light emitting unit is located under the ITO film layer. When the OLED display panel is turned on, light emitted from the light emitting unit passes through the ITO film layer (sometimes also referred to as an ITO layer), the Tx layer/Rx layer, and even the radiation unit of the millimeter wave antenna array, thus affecting the optical display effect of the display panel. In addition, it is difficult for the radiating element to form a desired shape for achieving a predetermined radiation characteristic under this structure, resulting in inefficiency of the antenna.
To this end, the applicant has proposed an improved display panel provided with a touch layer on which an antenna (antenna array) is provided, the antenna comprising at least one radiating element, the structural improvement of the touch layer improving the radiation efficiency of the antenna. The touch layer comprises two electrode layers (Tx electrode/layer and Rx electrode/layer) and a substrate (such as a transparent substrate and a flexible transparent substrate), wherein the two electrode layers are configured on two opposite sides of the substrate, one side adopts a metal layer, and the other side adopts an ITO film layer. Preferably, the thickness of the metal layer is not more than 500nm, so that the electrical conduction is satisfied and the light-emitting efficiency (namely, the conductivity and the light-emitting performance are both ensured) at the same time. Preferably, the thickness of the ITO film layer is 20-50 nm. The metal layer is etched to form a part of the metal layer to serve as a radiating unit (namely, a redundant electrode of metal with good electric conduction performance is utilized, and the radiating unit is not required to be additionally arranged), the radiating unit is combined into an antenna (the antenna is a millimeter wave antenna), the ITO film layer below the radiating unit is designed to avoid, the orthographic projection of the radiating unit to the transparent substrate side is not contacted with the ITO film layer (and has a certain gap), namely, the ITO on the lower side of the radiating unit is removed.
