In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be described in further detail in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

In the description of this application, it should be understood that the terms "center", "horizontal", "upper", "lower", "left", "right", "vertical", "horizontal", "top", " The "orientation", "inner", "outer" and other indicated orientations or positional relationships are based on the orientations or positional relationships shown in the drawings, only for the convenience of describing the application and simplifying the description, rather than indicating or implying the indicated devices or The element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present application. In addition, it should be noted that when an element is referred to as being “disposed on another element”, it may be directly connected to another element or there may be a centering element at the same time. When an element is considered to be “connected” to another element, it can be directly connected to another element or there can be a center element at the same time. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present.

As mentioned in the background art, traditional electronic devices such as mobile phones, tablet computers, etc., because of the need to integrate such as front camera, earpiece and infrared sensor elements, etc., can be set in the slotted area by notching the display (Notch) Cameras, earpieces, infrared sensor elements, etc. However, the slotted area is not used to display pictures, such as the "bang screen" in the prior art, or the method of making holes on the screen. For electronic devices that realize the camera function, external light can pass through the openings on the screen Enter the photosensitive element located at the bottom of the screen. However, these electronic devices are not full screens in the true sense, and cannot be displayed in various areas of the entire screen, for example, the screen cannot be displayed in the camera area.

In response to the above problems, technicians have developed a display screen that implements a full-screen display of electronic devices by providing a transparent display panel in the slotted area. Since the slotted area is usually set in the middle area of the display screen, the signal line on the left side of the slotted area cannot be connected to the signal line on the right side of the slotted area, so that the display panel in the non-slotted area cannot display .

To solve the above technical problems, an embodiment of the present application provides a display screen. FIG. 1 is a schematic structural diagram of a display screen in an embodiment. Referring to FIG. 1, the display screen 100 includes a display area 10 and a frame area 20. The display area 10 is used to display a screen. The frame area 20 is located around the display area 10, and the frame area 20 is provided with a frame, a driving circuit, and the like. In this embodiment, the display area 10 has an adjacent first display area AA1 and second display area AA2. At least part of the second display area AA2 is connected to the first display area AA1. The shape of the second display area AA2 may be a circle, an ellipse, a rectangle, or other irregular graphics. As shown in FIG. 1, in an embodiment, the second display area AA2 may be disposed at the top middle area of the display area 10, and the second display area AA2 is rectangular, so that there is three-face contact with the first display area AA1. It can be understood that the second display area AA2 may also be disposed in the left middle area of the display area 10 or the right middle area. Both the first display area AA1 and the second display area AA2 are used to display dynamic or static pictures.

With continued reference to FIG. 1, in one embodiment, the display screen 100 includes a first display panel 110 and a second display panel 120. The first display panel 110 is disposed in the first display area AA1. The second display panel 120 is disposed in the second display area AA2. The first display panel 110 and the second display panel 120 may be manufactured separately, or may be manufactured simultaneously to form an integrated screen.

The first display panel 110 includes a signal bus 130 and a signal connection line 140. The signal bus 130 is disposed on the bezel area 20 and located at the edge of the first display panel 110. In some embodiments, the signal connection line 140 is disposed on the second display panel 120 or at the junction of the second display panel 120 and the first display panel 110. In the embodiment shown in FIG. 1, the signal connection line 140 is located at the junction of the second display panel 120 and the first display panel 110, so that the second signal line 114 does not need to pass through the second display panel 120. It will affect the display of the second display panel 120. The first display panel 110 is also provided with a number of first signal lines 112 and a number of second signal lines 114. The first signal line 112 and the second signal line 114 have the same extending direction, and are both used to transmit the same kind of signal to a row / column of pixels. In FIG. 1, the two-dot chain line indicates the first signal line 112, and the dotted line indicates the second signal line 114. The thick solid line indicates the signal bus 130 and the signal connection line 140. In this embodiment, both ends of the first signal line 112 are connected to the signal bus 130, and only one end of the second signal line 114 is connected to the signal bus 130, that is, the second signal line 114 is located on the first display panel 110 The area opposite the slotted area, that is, the second display panel 120. The signal connection line 140 is connected to the end of the second signal line 114 that is not connected to the signal bus 130, and the signal connection line 140 is also connected to two first signals near the junction of the first display panel 110 and the second display panel 120 The

lines

112a and 112b are connected.

In the above display screen, the signal connection line 140 can be connected to the second signal line 114, and both ends of the signal connection line 140 are connected to a first signal line 112. Since both ends of the first signal line 112 are connected to the signal bus 130, the signal in the signal bus 130 can be transmitted to the second signal line 114 through the signal connection line 140 through the first signal line 112 , So that the second signal line 114 can be driven normally to ensure the normal display of the display screen.

In one embodiment, the signal bus 130 is an initialization signal bus, and both the first signal line 112 and the second signal line 114 are initialization signal lines (reference lines). At this time, the display circuit in the first display area AA1 has a compensation circuit, so it is necessary to provide an initialization signal for initialization through the initialization signal line. In this embodiment, since the signal connection line 140 is connected to the first signal line 112 and the second signal line 114, the signal transmitted therein is also an initialization signal. At this time, the signal bus 130 is used to provide an initialization signal to the first signal line 112 and the second signal line 114 to initialize the capacitance of the target pixel circuit and the anode of the OLED device. The initialization signals in the signal bus 130, the first signal line 112, the second signal line 114, and the signal connection line 140 are all at the same potential. Usually the initialization signal line must be wired at both ends, otherwise display problems will occur. In the conventional display screen, due to the presence of the second display panel 120, the signal bus 130 is interrupted, so that the initialization signal lines in the interrupted area cannot be routed at both ends, and a display abnormality problem occurs. The display screen in this embodiment can solve this problem well.

In some embodiments, the signal connection line 140 may be disposed on the second display panel 120 and penetrate the second display panel 120. When the signal connection line 140 penetrates the second display panel 120, the signal connection line 140 is disposed on the second display panel 120 The non-light-emitting part of will not affect the normal display of the second display area AA2, ensuring the normal display of the display screen. Furthermore, in an embodiment, the signal connection line 140 should avoid the area where the camera 930 in the second display panel 120 is located, so as not to affect the operation of the camera.

As shown in FIG. 2, in an embodiment, the second display area AA2 includes a first sub-display area AA22 and a second sub-display area AA24, and the second display panel 120 includes a correspondingly arranged first sub-display panel 1201 and second Sub display panel 1202. A photosensitive device may be provided under the second sub-display panel 1202. The signal connection line 140 is provided in the first sub-display panel 1201. In this embodiment, the number of the second sub-display areas AA24 is two, and they are all surrounded by the first sub-display area AA22. In other embodiments, the number of the second sub-display area AA24 may also be set to one. The number of the second sub-display area AA24 can be determined according to the position setting of the photosensitive device in the display terminal. For example, when the front camera of the display terminal uses a dual camera, two second sub-display areas AA24 may be provided, and each second sub-display area AA24 corresponds to one camera.

In another embodiment, the signal connection line 140 may also be disposed in the second sub-display panel 1202. At this time, the signal connection line 140 is a transparent metal oxide, so that it does not affect the transparency of the second display panel 120.

In the embodiment shown in FIG. 1, the signal connection line 140 is disposed at the junction of the second display panel 120 and the first display panel 110 and is also located in the non-light emitting portion, so as not to affect the first display area AA1 and the first The normal display of AA2 in the second display area. The signal connection line 140 may be metal or transparent metal oxide. For example, when the signal connection line 140 is a transparent metal oxide, indium tin oxide (ITO), indium zinc oxide (IZO), silver-doped indium tin oxide (Ag + ITO), and silver-doped indium zinc oxide can be used (Ag + IZO) at least one of them. By setting the signal connection line 140 as a transparent metal oxide, it can be ensured that when the second display panel 120 is a transparent display panel, it will not affect the transparency of the display panel.

In some embodiments, the diameter of the signal bus 130 and the signal connection line 140 is larger than the diameter of the first signal line 112 and greater than the diameter of the second signal line 114, that is, the width of the signal bus 130 and the signal connection line 140 The cross-section is larger than the cross-sectional areas of the first signal line 112 and the second signal line 114, so as to meet the usage requirements.

In some embodiments, the two

first signal lines

112a and 112b connected to the signal connection line 140 are disposed at the junction of the first display area AA1 and the second display area AA2. At this time, the two

first signal lines

112a and 112b and the signal connection line 140 may form an isolation structure surrounding the second display area AA2, thereby avoiding interference between the first display area AA1 and the second display area AA2, and ensuring display The normal display of the screen.

In some embodiments, the first display panel 110 and the second display panel 120 may be separately manufactured and then spliced, or may be simultaneously manufactured to form an integrated screen. At this time, the first display panel 110 and the second display panel 120 share one substrate.

In an embodiment, the second display panel 120 may be a transparent or transflective display panel. The transparency of the second display panel 120 can be achieved by using various layers of materials with good light transmittance. For example, the light transmittance of the film layers of each structure is greater than 90%, so that the light transmittance of the entire display panel can be more than 70%. Further, the light transmittance of the film layers of each structure is greater than 95%, which further improves the light transmittance of the display panel, and even makes the light transmittance of the entire display panel above 80%. Specifically, the conductive trace can be set to at least one of ITO, IZO, Ag + ITO, or Ag + IZO. The insulating layer material is preferably SiO ₂ , SiN _x, and Al ₂ O _{3. The} pixel definition layer is highly transparent. material.

It can be understood that the transparency of the second display panel 120 may also be implemented by other technical means. The transparent or transflective display panel can display the picture normally when it is in the working state, and when the display panel is in the state of other functional requirements, external light can be irradiated through the display panel to the photosensitive placed under the display panel Devices, etc.

By setting the second display panel 120 as a transparent or transflective display panel, a photosensitive device such as a camera can be disposed under the second display panel 120. It can be understood that the second display area AA2 can display images normally when the photosensitive device is not working, and when the photosensitive device is working, the second display area AA2 changes with the change of the display content of the overall display, such as showing that it is shooting The external image or the second display area AA2 may also be in a non-display state, thereby further ensuring that the photosensitive device can collect light through the second display panel 120 of the second display area AA2. In other embodiments, the light transmittances of the first display area AA1 and the second display area AA2 may also be the same, that is, the light transmittances of the first display panel 110 and the second display panel 120 may be the same, so that the entire display The screen has good light transmission uniformity, ensuring that the display screen has a good display effect.

In one embodiment, the first display panel 110 is an AMOLED display panel, and the second display panel 120 is a PMOLED display panel. Specifically, please refer to FIG. 3, the PMOLED display panel includes a substrate and a plurality of first electrodes 123 disposed on the substrate. The shape of the first electrodes 123 is a plurality of arcs that are connected to each other. In this embodiment, a plurality of first electrodes 123 extend in parallel in the same direction, and adjacent first electrodes 123 have a pitch. In the extending direction of the first electrode 123, the width of the first electrode 123 continuously changes or intermittently changes, and the pitch continuously changes or intermittently changes. As can be seen from FIG. 3, the extending direction of the first electrode 123 is its longitudinal direction. The first electrode may be an anode electrode or a cathode electrode, or the first electrode may include both an anode electrode and a cathode electrode. By setting the first electrode as a connected arc electrode, when the external light passes through the first electrode, the position of the generated diffraction fringe is different between the different width positions of the first electrode and the different distances between adjacent first electrodes . The diffraction effects at different positions cancel each other, which can effectively reduce the diffraction effect, thereby ensuring that when the camera is disposed below the second display panel 120, the graphics obtained by the photograph have high definition.

In an embodiment, the sub-pixel shape of the second display panel 120 is one of a circle, an ellipse, a dumbbell, and a gourd. That is, a pixel opening is provided in the pixel definition layer of the second display panel 120. Each pixel opening corresponds to a light emitting structure. The shape of each pixel opening is one of a circle, an ellipse, a dumbbell, and a gourd. For details, refer to FIG. 4. By setting each sub-pixel to one of a circle, an ellipse, a dumbbell, and a gourd, the diffraction effect can also be weakened. In addition, the circular, elliptical, dumbbell or gourd shape can maximize the area of each sub-pixel to further increase the light transmittance.

In one embodiment, the first display panel 110 is an AMOLED display panel, and the second display panel 120 is an AMOLED-like display panel. The AMOLED-like display panel means that its pixel circuit includes only one switching device (ie, driving TFT) without a capacitor structure. The other structure of the AMOLED-like display panel is the same as the AMOLED display panel. The second display panel 120 is an AMOLED-like display panel as an example for description.

FIG. 5 is a schematic structural diagram of a second display panel in another embodiment, where the second display panel is an AMOLED-like display panel. This type of AMOLED display panel includes a substrate 810 and a plurality of pixel circuits 820 (that is, TFT arrays) disposed on the substrate 810. A first electrode layer is provided on the pixel circuit 820. The first electrode layer includes a plurality of first electrodes 830. The first electrode 830 corresponds to the pixel circuit 820 in one-to-one correspondence. The first electrode 830 here is an anode. The AMOLED-like display panel further includes a pixel definition layer 840, which is disposed on the first electrode 830. The pixel definition layer 840 has a plurality of pixel openings 870, and a light emitting structure 850 is disposed in the pixel openings 870 to provide sub-pixels (not shown), and the sub-pixels correspond to the first electrodes 830 in one-to-one correspondence. A second electrode 860 is provided above the light emitting structure 850. The second electrode 860 is a cathode, and the cathode is a surface electrode, that is, an entire surface electrode formed of an entire surface electrode material. The pixel circuit 820 is provided with a scanning signal line, a data signal line, and a TFT switching device. Both the scanning signal line and the data signal line are connected to the TFT switching device. The scan signal line controls the turning on and off of the TFT switching device. When the pixel is turned on, the data signal line provides a driving current to the first electrode 830 to control the sub-pixel to emit light.

In this embodiment, the first signal line 112 is disposed below the pixel definition layer 840 and below the pixel circuit, so that the two are spatially offset from each other, reducing crosstalk between each other. In other embodiments, the first signal line 112 is disposed below the pixel definition layer 840, and is completed in the same process step as the conductive layer in the pixel definition layer 840, so there is no need to add additional processes during preparation Increase the complexity of preparation. In another embodiment, the first signal line 112 is disposed under the pixel definition layer 840 and between the pixel circuit 820 and the first electrode 830.

In one embodiment, the substrate 810 may be a rigid substrate, such as a transparent substrate such as a glass substrate, a quartz substrate, or a plastic substrate; the substrate 810 may also be a flexible substrate, such as a PI film, etc., to improve the transparency of the device. The light emitting structure 850 may be an OLED (Organic Light-Emitting Diode, organic light emitting diode).

FIG. 6 is a schematic diagram of the circuit principle of the pixel circuit 820 in an embodiment. Unlike the pixel circuit of a conventional AMOLED display panel, the pixel circuit 820 only includes a switching device, and does not include storage capacitors and other elements, thereby forming a capacitor-less structure. In this embodiment, the pixel circuit 820 includes a switching device. The switching devices correspond to the first electrodes 830 in one-to-one correspondence, that is, one sub-pixel corresponds to one switching device. The switching device includes a first terminal 2a, a second terminal 2b, and a control terminal 2c. For details, see the subsequent detailed introduction. The scan signal line is connected to the control terminal 2c of the switching device, the data signal line is connected to the first terminal 2a of the switching device, and the first electrode 830 is connected to the second terminal 2b of the switching device. As shown in Figure 8. In the above pixel circuit 820, the first end 2a of the switching device is connected through the data signal line, and the control terminal 2c of the switching device is connected to the scanning signal line, which can reduce the number of switching devices in the pixel circuit 820 to one, greatly reducing the load of the scanning signal line Current and load current of the data signal line.

The scanning signal line in the above display panel controls the opening and closing of the pixel circuit 820, and only needs to provide the switching voltage required by the switching device in the pixel circuit 820, and does not need to input the current of the light emitting structure (OLED), which greatly reduces the load of the scanning signal line The current makes the scanning signal line can be made of transparent materials such as ITO. In addition, when the pixel circuit 820 is turned on, the data signal line provides a driving current to the anode to control the sub-pixel to emit light. The data signal line only needs to supply the driving current of one sub-pixel at a time, and the load of the data signal line is also small. Therefore, the data signal line can also use transparent materials such as ITO, thereby improving the light transmittance of the display screen. The surface electrodes (cathode) are shared by multiple sub-pixels, and the current of a row of sub-pixels is provided by the entire surface of the cathode at each moment. It does not require negative photoresist to separate the cathode.

In an embodiment, the first electrode 830 may be one of a circle, an ellipse, a dumbbell, and a gourd. For details, refer to FIG. 4. By setting the first electrode 830 to be circular, elliptical, dumbbell-shaped, or gourd-shaped, the diffraction effect can also be weakened. In an embodiment, the shape of the pixel opening in the pixel definition layer 840 is one of a circle, an ellipse, a dumbbell, and a gourd, as shown in FIG. 4, so that the diffraction effect can also be weakened. In an embodiment, the signal lines such as the scan signal line and the data signal line may use the connected arc-shaped traces shown in FIG. 4 to achieve the effect of improving diffraction.

In an embodiment, in order to improve the light transmittance, no polarizing plate may be provided in the second display area AA2, that is, no polarizing plate is provided in the second display panel 120. Moreover, since the second display panel 120 in the second display area AA2 can effectively improve the diffraction phenomenon caused by the external light transmitting through the second display area AA2, the quality of the image captured by the camera 930 on the display terminal can be effectively improved to avoid the diffraction As a result, the captured image is distorted, and at the same time, the accuracy and sensitivity of the light sensor in sensing external light can also be improved.
