Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
At present, terminals using an AMOLED display panel are becoming more popular, and meanwhile, for the needs of video telephony and the like, a camera is also installed on the front surface of the display panel in the terminal equipment, or a corresponding optical sensor is installed for the needs of detection. Cameras, optical sensors, or other optical components often need to capture external optics through a lens.
In some related art, as shown in fig. 1, the terminal 10 has a display panel 11, and further includes a camera 12 disposed on the same side as the display panel 11. The camera 12 is required to be arranged, so that the display panel 11 cannot extend to the uppermost end of the side face of the terminal 10, a part of space is left at the upper end and cannot be used for displaying, the screen occupation ratio is low, and the user requirement cannot be met.
In other related art, as shown in fig. 2, another terminal 20 has a display panel 21, and further includes a camera 22 disposed on the same side as the display panel 21. Compared with the design in the former scheme, the area of the display panel 21 in the terminal 20 is further enlarged, the screen occupation ratio is improved, but a space is required to be reserved at the position of the camera 22 for setting holes and the like, and the display cannot be carried out.
In some related arts, as shown in fig. 3, another terminal 30 has a display panel 31, and further includes an optical component 32 such as a camera or an optical sensor disposed below the display panel 31, compared with the first two designs, the terminal 30 employs the optical component 32 under the screen, and external incident light can partially penetrate through the display panel 31 and enter the optical component 32. The mode can improve the screen occupation ratio to the maximum extent. But also affects the lighting effect. Meanwhile, as shown in fig. 4, in the AMOLED display panel, a light emitting structure 40 is included, and the light emitting structure 40 generally includes a first electrode 41, a light emitting material 42, and a second electrode 43. In order to improve the brightness of the display panel 31, a light reflecting layer may be disposed in the second electrode 43 to reflect light emitted from the light emitting material 42. When the optical assembly 32 is disposed under the screen, as shown in fig. 5, the second electrodes 43 are disposed at intervals, so that external incident light can enter the optical assembly 32 through the second electrodes 43, when the incident light enters the optical assembly 32, part of the light is reflected on the lens surface of the optical assembly 32, and the reflected light is projected to the back of the second electrodes 43 and reflected to the optical assembly 32 again through the reflective layer, thereby generating an optical path difference, causing a decrease in quality of an image captured by the camera, or causing a false judgment of the optical sensor.
In order to solve the above technical problem, the present disclosure provides a display panel 50, which can improve the image quality collected by a camera disposed under a screen, and reduce the influence of the display panel on the lighting of the camera. As shown in fig. 11, the display panel 50 may be applied to the terminal 80, the terminal 80 may include the display panel 50 and an optical assembly 60 located below the display panel 50, and the optical assembly 60 may be a camera or an optical sensor or other devices that receive light. Wherein display panel 50 can have the printing opacity display area 500 that corresponds with optical component 60, optical component 60 sets up in printing opacity display area below, outside light passes display panel 50 through printing opacity display area 500 and gets into optical component 60, display panel 50's printing opacity display area 500 can be different with non-printing opacity display area's setting, with the penetration rate that improves incident light, even make more light can enter into optical component 60, make optical component 60's daylighting effect better, the reliability is improved, make the imaging quality of camera higher or improve optical sensor's rate of accuracy.
As shown in fig. 6 and 7, the display panel 50 may include a light emitting structure 51, a thin film transistor layer 52 disposed below the light emitting structure, and a substrate 53 disposed below the thin film transistor layer 52. The display panel 50 using the AMOLED, a circuit of the thin film transistor layer 52, such as a driving circuit, is fabricated on the substrate 53, and then the light emitting structure 51 is fabricated on the circuit of the thin film transistor layer 52. In the embodiments of the present disclosure, the upper direction generally refers to a direction toward the outer side of the display screen, and also refers to a direction from the inner side of the terminal toward the outer side of the terminal. The light emitting structure 51 may include a first electrode 511, a light emitting material layer 512, and a second electrode 513. The first electrode 511 is located at the top and may be made of a transparent material, so that light can pass through the first electrode, thereby ensuring that light of a display screen can be emitted from the lower side to the upper side, and external light required to be collected by the optical assembly 60 under the screen can be ensured to enter the display screen. The light emitting material layer 512 is disposed under the first electrode 511, and can emit light of a corresponding color according to a control signal, and the light is emitted from the first electrode 511 to form a display image. The second electrode 513 is disposed under the light emitting material layer 512, and has a polarity opposite to that of the first electrode 511. In some embodiments, the second electrode 513 can be an anode and the first electrode 511 can be a cathode. The anode removes electrons by current to form electron holes, and the cathode emits electrons by current, which pass through the light-emitting material layer 512 to excite the light-emitting material layer 512 to emit light.
In the embodiment of the disclosure, the second electrode 513 has a gap for light to pass through at least in the light-transmitting display region, and the second electrode 513 includes a light-reflecting layer 5132 and an anti-reflection layer 5133 disposed on a side of the light-reflecting layer 5132 close to the optical element, where the anti-reflection layer 5133 is used for absorbing light reflected by the optical element 60. The anti-reflection layer 5133 may be provided in other regions, and the anti-reflection layer 5133 may be provided only in the light-transmissive display region to save cost. In order to ensure the display quality of the display panel 50, a light reflecting layer 5132 is required, and the light reflecting layer 5132 may be formed of Ag (silver). The light reflecting layer 5132 cannot make the incident light from above continue to be sent downward, so in order to ensure that the incident light from the outside can smoothly pass through and enter the lens of the optical element 60, the second electrode 513 forms a gap for the light to pass through at least in the light-transmitting display area 500. Since the lens of the optical assembly 60 is made of a transparent material, light may also be partially reflected when entering the lens surface, and as mentioned above, if the reflected light is reflected back to the lens through the reflective layer 5132, the image quality of the camera may be degraded or the inspection reliability of the optical sensor may be reduced due to the optical path difference. In the embodiment of the disclosure, an anti-reflection layer 5133 is further disposed below the reflective layer 5132, and the anti-reflection layer 5133 can prevent light from being reflected and absorb light, so that the influence caused by external light being reflected by the lens of the optical assembly 60 and then reflected again by the reflective layer 5132 to the lens can be avoided.
In some embodiments, the anti-reflection layer 5133 may be a black material, which absorbs light by its black property to avoid light reflection. For example, the black layer may be formed by an ink screen printing technique, or may be a black organic material. In some embodiments, the Black material of the anti-reflection layer 5133 may be formed by a Black Matrix (Black Matrix) material, which may be made of one or more of the following materials to absorb light: the material may be Cr (chromium), CrOx (chromium oxide), or Black Resin.
In the embodiment of the present disclosure, as shown in fig. 8 and 9, the second electrode 513 may further include a first transparent electrode layer 5134 disposed below the light reflection layer 5132. The first transparent electrode layer 5134 may be a transparent conductive film formed of ITO (Indium Tin Oxide). In an embodiment, as shown in fig. 8, the anti-reflection layer 5133 may be disposed between the light-reflecting layer 5132 and the first transparent electrode layer 5134, and the anti-reflection layer 5133 may be formed on the lower surface of the light-reflecting layer 5132 or on the upper surface of the first transparent electrode layer 5134, so as to be disposed between the light-reflecting layer 5132 and the first transparent electrode layer 5134 and prevent the light reflected by the lens from being reflected again therebelow. In another embodiment, as shown in fig. 9, an anti-reflection layer 5133 can also be disposed on the lower surface of the first transparent electrode layer 5134, which is more convenient to manufacture and can prevent the light reflected by the lens from being reflected again.
In other embodiments of the present disclosure, as shown in fig. 10, the second electrode 513 may also include a light-shielding electrode layer 5135 disposed below the light-reflecting layer 5132, where the light-shielding electrode layer 5135 is made of a non-transparent and anti-reflective material, and the light-shielding electrode layer 5135 serves as an anti-reflective layer. In this embodiment, compared with the original structure, an extra layer is not needed to be arranged for shading, but the electrode layer below is made of an opaque material which does not reflect light, so that light reflected by the lens below is prevented from being reflected again, and meanwhile, the whole thickness of the display panel 50 is not required to be increased.
As shown in fig. 8, 9, and 10, the second electrode 513 further includes: a second transparent electrode layer 5131, wherein the second transparent electrode layer 5131 is disposed above the light reflecting layer 5132. In this embodiment, the second electrode 513 further includes a second transparent electrode layer 5131 disposed above the reflective layer 5132, and the second transparent electrode layer 5131 is made of a transparent material, so that light emitted from the light emitting material layer 512 can pass through the second transparent electrode layer 5131, and thus, the display brightness can be improved by reflection of the reflective layer 5132. In some embodiments, the second transparent electrode layer 5131 may also be a transparent conductive film formed of ITO, and the second transparent electrode layer 5131, the light reflection layer 5132, and the first transparent electrode layer 5134 may form an anode structure of ITO/Ag/ITO.
The display panel 50 of any of the above embodiments is provided with the anti-reflection layer below the reflection layer, so that the light reflected by the lens of the optical assembly 60 is prevented from entering the lens again through reflection of the reflection layer, which causes influence of optical path difference on an image, the imaging quality of the camera under the screen is improved, and the sensing quality of the optical sensor under the screen can also be improved. To the terminal of full face screen, when can improving the screen and account for, guarantee positive optical assembly and set up the adverse effect that also can avoid light collection under the screen, guarantee light collection's reliability.
In some embodiments, a plurality of driving circuits may be formed on the thin film transistor layer 52 for driving the light emitting devices in the light emitting material layer 512 to emit light, wherein the driving circuits corresponding to some or all of the light emitting devices in the light transmissive display region 500 are disposed outside the light transmissive display region 500. Because the driving circuit is generally opaque material, can hinder the light propagation, be the main factor who influences the light transmissivity of thin film transistor layer 52, in this embodiment, through the whole or partial region of setting outside the printing opacity display region 500 of the driving circuit with printing opacity display region 500 light emitting device for the driving circuit quantity in the printing opacity display region 500 reduces, thereby the light transmissivity has been improved, make during external light can be more the optical assembly 60 who enters into printing opacity display region below, the daylighting efficiency of optical assembly 60 has been improved. The image shot by the camera can be clearer, and the sensing of the optical sensor can be more accurate.
Based on the same concept, the present disclosure also provides a display screen, as shown in fig. 7, the display screen of the present disclosure includes the display panel 50 according to any of the foregoing embodiments, and an optical assembly 60 disposed below the display panel 50, and the optical assembly 60 corresponds to the light-transmissive display area of the display panel 50.
The display screen of the present disclosure may emit light through the light emitting material layer 512, and the emitted light may be diffused to the outside of the display screen to form a display image. External light can enter the optical assembly 60 below the light-transmitting display area of the display panel 50 through the display panel 50, so that the optical assembly 60 can collect external light, for example, a camera can form a picture or a video or a preview image, or for example, an optical sensor under a screen performs sensing. There may be a plurality of optical assemblies 60 disposed below the display panel 50, for example, a camera and an optical sensor are disposed at the same time, and correspondingly, a plurality of light-transmitting display areas of the display panel 50 may also be disposed correspondingly. Since the anti-reflection layer is disposed below the reflective layer 5132 in the second electrode 513 of the display panel 50, the light reflected by the lens is prevented from entering the lens again through reflection of the reflective layer, which results in an influence of optical path difference on light collection.
