Detailed Description
The present disclosure will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments do not limit the disclosure, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the disclosure.
The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
In the following, some embodiments of the present disclosure will be described in detail with reference to the accompanying drawings, and features in the following examples and embodiments may be combined with each other without conflict.
As shown in fig. 1, a display panel 10 according to an embodiment of the present disclosure includes a substrate 1, a driving circuit layer 2 on the substrate 1, a first electrode layer 3 on the driving circuit layer 2, a light emitting layer 4 on the first electrode layer 3, and a second electrode layer 5 on the light emitting layer 4. The first electrode layer 3 is an anode layer, the second electrode layer 5 is a cathode layer, and both the first electrode layer 3 and the second electrode layer 5 are made of transparent materials. The arrangement is such that the display panel 10 can meet the requirement of normal display and can perform light transmission control according to the use requirement.
In the present disclosure, the transparent material may be any transparent conductive material. Preferably, at least one of silver, magnesium-silver alloy, indium tin oxide, indium zinc oxide, etc., for example, may be silver-doped indium tin oxide or silver-doped indium zinc oxide. Preferably, the transparent material for preparing the first electrode layer 3 and the second electrode layer 5 is silver-doped indium tin oxide or silver-doped indium zinc oxide, so as to reduce the resistance of the first electrode layer 3 and the second electrode layer 5 on the basis of ensuring high light transmittance of the display panel 10.
The substrate 1 may be a rigid substrate, such as a transparent substrate like a glass substrate, a quartz substrate, or a plastic substrate. The substrate 1 may also be a flexible transparent substrate, such as a Polyimide (PI) film, to improve the transparency of the device. The light emitting layer 4 includes a plurality of light emitting structure pieces, which are correspondingly disposed on the first electrode layer 3. The Light-Emitting layer 4 may be an OLED (Organic Light-Emitting Diode).
As shown in fig. 1 in conjunction with fig. 4, the driving circuit layer 2 includes driving traces 21 and driving control switch circuits (not shown). The driving trace 21 is located below the first electrode layer 3, and the driving trace 21 is used for connecting light-emitting pixels on the light-emitting layers 4. The driving control switch circuit is disposed at the periphery of the first electrode layer 3, i.e., the driving control switch circuit is located outside the display region (i.e., the transparent display region) of the display panel 10, thereby ensuring the light transmittance. In this embodiment, in order to make the display panel 10 satisfy the transparent effect, the driving control circuit is moved to the periphery of the display panel 10 except for the necessary driving traces 21 on the display panel 10, so as to prevent the opaque driving control switch circuit from affecting the light transmittance of the display panel 10.
In addition, the display panel 10 further includes a first pixel defining layer 6 disposed between the first electrode layer 3 and the second electrode layer 5. Specifically, the first pixel defining layer 6 is provided with a plurality of pixel openings, the light emitting layer 4 includes a plurality of light emitting structure blocks, the light emitting structure blocks include a plurality of light emitting pixels, and the plurality of light emitting structure blocks are disposed in the plurality of pixel openings in a one-to-one correspondence manner.
As shown in fig. 2, in an embodiment, the display panel 10 further includes an encapsulation layer 7 on the second electrode layer 5. Wherein, the packaging layer 7 is hard screen packaging or organic film packaging.
The display panel 10 of the present disclosure is manufactured by using transparent materials for the anode layer and the cathode layer, so that the display panel 10 can maintain the light transmittance of the display panel 10 while satisfying the display effect, and keep the PPI of the display panel 10 from decreasing, thereby reducing the negative visual effects of "granular feeling" and "black frame" of the existing display panel 10, and thus satisfying the requirement of imaging of the camera under the screen.
As shown in fig. 3 and 4, according to still another aspect of the embodiment of the present disclosure, there is also provided a display screen 100, the display screen 100 including: a non-transparent display area 101 and a transparent display area 102. The transparent display area 102 is made by the display panel 10 of the above embodiments. The transparent display area 102 can be disposed at any position of the display screen 100 according to the application requirement.
The non-transparent display region 101 of the present disclosure has no transparent effect, and the non-transparent display region 101 is formed by sequentially stacking a substrate 1, a driving circuit layer 2, a first electrode layer 3, a light emitting layer 4, and a second electrode layer 5. The non-transparent display area 101 and the transparent display area 102 have the same structure layer, except that: the first electrode layer 3 and the second electrode layer 5 of the transparent display area 102 are made of a transparent material.
The first electrode layer 3 is an anode layer, and the second electrode layer 5 is a cathode layer. When the display screen 100 is used to prepare an anode layer and a cathode layer, the non-transparent display area 101 and the transparent display area 102 need to be subjected to a film coating process in steps, taking the anode as an example: when preparing the anode layer, the non-transparent display area 101 is coated to complete the non-transparent anode coating, and the anode layer can be made of the anode material which is commonly used in the existing display screen; and then the corresponding transparent display area 102 is coated with a transparent material, thus completing the coating process of the anode in the display screen 100. The cathode layer may be coated in the same or similar manner as the anode layer, and will not be described herein again.
It should be noted that, in an alternative embodiment, the display screen 100 may also be provided with only the transparent display area 102, and the transparent display area 102 is made by the display panel 10 of the above embodiments.
The driving circuit layer 2 in the transparent display area 102 of the present disclosure includes driving traces 21 and driving control switch circuits. The driving trace 21 is located below the first electrode layer 3 in the display panel 10, and the driving control switch circuit is disposed in the non-transparent display region 101 and located at the periphery of the display panel 10.
In this disclosure, the driving circuit layer of the non-transparent display area 101 may also include a driving trace and a driving control switch circuit, and the driving trace and the driving control switch circuit of the non-transparent display area 101 are disposed below the first electrode layer of the non-transparent display area 101 and are matched with the corresponding light emitting layer to control the light emission of the light emitting layer. Since the non-transparent display region 101 does not need a transmissive display, the opaque drive control switch circuits in the transparent display region 102 are disposed in the non-transparent display region 101. Further, in order to reduce the lines between the driving control switch circuit and the driving traces 21 in the transparent display area 102 as much as possible, the driving control switch circuit is disposed in the non-transparent display area 101 at a portion adjacent to the transparent display area 102.
Alternatively, the drive control switch circuit may be disposed in a non-display area of the electronic device having the display screen.
As shown in fig. 5, according to still another aspect of the embodiments of the present disclosure, there is further provided an electronic device 200, where the electronic device 200 includes a device body 201, a camera 202 disposed on the device body 201, and the display screen 100 according to the above embodiments. The display screen 100 is assembled on the device body 201, and the camera 202 is correspondingly arranged in the transparent display area 102 of the display screen 100, so that the arrangement of the camera 202 under the screen is realized. The electronic device 200 of the present disclosure may be any device having a display screen, for example, a mobile communication terminal (such as a mobile phone), a PDA (Personal Digital Assistant), a mobile computer, a tablet computer, a wearable device, and the like.
The display screen 100 of the present disclosure includes the transparent display area 102, and the transparent display area 102 can also be controlled to be in a transparent state on the premise of ensuring normal display, so that the camera 202 can shoot through the transparent display area 102, and the shooting effect of the camera 202 is not affected. When shooting is not needed, the transparent display area 102 can normally display pictures; when the electronic device 200 is in the shooting state, the transparent display area 102 is not displayed, but is in a transparent state, so that the camera 202 can shoot conveniently, and thus, the full-screen display of the electronic device 200 is satisfied.
Preferably, the size of the transparent display area 102 is matched with that of the camera 202, so as to reduce the size of the transparent display area 102 as much as possible, so as to reduce the size of an area which is not displayed on the display screen 100 when the camera 202 performs shooting, thereby improving the visual perception of a user in the using process.
The display screen of the electronic equipment is provided with the transparent display area, the camera is arranged under the transparent display area, the transparent display area can meet the display requirement and can be controlled to be in a transparent state to be shot by the camera, and therefore the requirement of comprehensive screen design can be met. The anode layer and the cathode layer are made of transparent materials, so that the transparent display area can meet the display effect and simultaneously keep the light transmittance of the transparent display area, and imaging of the camera under the screen can be achieved.
