Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In the description of the present application, it is to be understood that the terms "center", "lateral", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner" and "outer" etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present application and simplifying the description, but do not indicate or imply that the referred device or element must have a particular orientation, be constructed in a particular orientation, and be operated, and thus should not be construed as limiting the present application. Further, when an element is referred to as being "formed on" another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present.
As described in the background art, since the conventional electronic devices such as mobile phones and tablet computers need to integrate the front camera, the headphone, the infrared sensing element, etc., the camera, the headphone, the infrared sensing element, etc. can be disposed in the slotted area by slotting (Notch) on the display screen. However, the slotted region is not used for displaying pictures, such as a bang screen in the prior art, or a hole is formed in the screen, and for an electronic device implementing a camera function, external light can enter the photosensitive element located below the screen through the hole in the screen. However, these electronic devices are not all full-screen in the true sense, and cannot display in each area of the whole screen, for example, the camera area cannot display the picture.
In view of the above problems, the technical staff have developed a display screen, which realizes the full-screen display of the electronic device by setting a transparent display panel in a slotted area. Since the slotted area is generally disposed in the middle area of the display screen, the signal lines on the left side of the slotted area cannot be connected with the signal lines on the right side of the slotted area. If the driving chip (IC) is located at the left side of the slotted region, the signal line corresponding to the right side of the slotted region is not connected with the driving IC, thereby causing display abnormality. Because the slotted area is provided with the transparent display panel, the drive ICs are arranged on two opposite sides of the slotted area, so that the signal lines on two sides can be correctly connected with the drive ICs, and the display screen can normally display. The two sides are respectively provided with the driving ICs, so that cost waste is caused, and the two driving ICs need to be synchronous, so that the controllability is poor. And because drive ICs are required to be placed on two sides, the frames on the two sides are large, and normal display of the full screen is not facilitated.
In order to solve the above technical problem, an embodiment of the present application provides a display screen, which can solve the above problem well. Fig. 1 is a schematic structural diagram of a display screen in an embodiment. Referring to fig. 1, the display screen has a first display area AA1 and a second display area AA 2. At least a partial area of second display area AA2 is completely enclosed by first display area AA 1. The shape of the second display area AA2 may be circular, oval, rectangular or other irregular figure. In one embodiment, second display area AA2 may be disposed in a top middle region of the display screen, and second display area AA2 is rectangular such that there is three-sided contact with first display area AA1, as shown in fig. 1. In another embodiment, second display area AA2 may also be disposed inside first display area AA1 such that four sides of second display area AA2 are connected to first display area AA 1. In fig. 1, the number of the first display area AA1 and the second display area AA2 is one, and in other embodiments, the number of the first display area AA1 and the second display area AA2 may be two or more. The first display area AA1 and the second display area AA2 are both used to display a dynamic or static picture.
In the present embodiment, the first driving signal line 114 in the first display area AA1 is blocked by the second display area AA 2. For example, the blocked first driving signal line 114 may be one of a data signal line and a scanning signal line, and may be determined according to the relative position relationship of the display regions and the arrangement of a driving circuit and the like. A plurality of signal connection lines 112 are disposed in the second display area AA 2. The number of the signal connection lines 112 is equal to the number of the first driving signal lines 112 blocked by the second display area AA 2. The signal connection line 112 passes through both sides of the second display area AA2 and connects the first driving signal line 114, which is blocked, to prevent display abnormality.
In this embodiment, the display panel further includes a timing control circuit (not shown). The time sequence control circuit is arranged in a frame area (or a non-display area) of the display screen. The time sequence control circuit is used for staggering the potential jumping point of the signal in the second driving signal line with the signal writing time of the first display area, so that the interference of the signal transmitted in the second driving signal line on the signal writing of the first display area is avoided, and the normal display of the display screen is ensured.
In an embodiment, the timing control circuit may control a potential transition point of a signal in the second driving signal line to be at least a predetermined time ahead or at least a predetermined time behind a signal writing point of the second display region. The preset time period may be set as required, for example, set to 5 microseconds, so as to ensure that the two do not interfere with each other. Specifically, the purpose of the staggering can be achieved by adjusting the signal timing of the second driving signal line or adjusting the signal timing in the first driving signal line. In this embodiment, the timing of the signals in the first driving signal line and the second driving signal line is adjusted at the same time, so that the potential transition point of the signal in the second driving signal line is at least advanced by a preset time or at least delayed by a preset time than the signal writing point of the second display region. For example, the pulse widths of the first driving signal line 114 and the second driving signal line may be adjusted so that the potential transition point of the signal in the second driving signal line is shifted by the signal writing time of the first display panel 110.
In an embodiment, the timing control circuit may control the potential transition point of the second driving signal in the second display area AA2 to stagger the signal writing time in the entire first display panel 110, thereby ensuring that the signal driving in the second display area AA2 does not interfere with the display in the first display area. In another embodiment, the timing control circuit may also control the potential transition point of the signal in the second driving signal line in the second display area AA2 to shift the signal writing time of the area where the first driving signal line 114 connected through the signal connection line 112 in the first display area AA1 is located, that is, to shift the area where the first driving signal line 114 is located. When the signal writing in the first display area AA1 is mainly determined by the data signal, the timing control circuit may also control the potential transition point of the signal in the second driving signal line in the second display area AA2 to miss the signal writing time in the area where the first data signal line connected through the signal connection line 112 in the first display area AA1 is located, thereby preventing the driving process of the second display area AA2 from interfering with the signal writing in the first display area AA 1. And ensuring normal display of the display screen.
In one embodiment, the second display area AA2 includes a first sub-display area AA22 and a second sub-display area AA24, as shown in fig. 2. A photosensitive device may be disposed under the second sub-display area AA 24. In the present embodiment, the number of the second sub-display areas AA24 is two, and each of the second sub-display areas AA24 is surrounded by the first sub-display area AA 22. In other embodiments, the number of the second sub-display area AA24 may be set to one. The number of the second sub-display areas AA24 may be determined according to the position setting of the light sensing device in the display terminal. For example, when the front camera of the display terminal adopts a dual camera, two second sub-display areas AA24 may be provided, and each second sub-display area AA24 corresponds to one camera. In this embodiment, the signal connection line 112 is disposed in the first sub-display area AA22, so that the area where the photosensitive device such as a camera is located can be avoided, and the operation of the photosensitive device such as a camera is not affected.
The display screen includes a first display panel 110 and a second display panel 120. The first display panel 110 is disposed in the first display area AA 1. The second display panel 120 is disposed in the second display area AA 2. The first display panel 110 and the second display panel 120 may be fabricated separately and then spliced, or fabricated at the same time to form an integrated screen. At this time, the first display panel 110 and the second display panel 120 share one substrate. The first display panel 110 is an AMOLED display panel; the second display panel 120 is a PMOLED display panel, an AMOLED display panel, or an AMOLED-like display panel. Fig. 3 is a cross-sectional view of the second display panel 120 in an embodiment. In the present embodiment, the first driving signal line 114 connected to the signal connection line 112 is a first data signal line, i.e., an AM data signal line. In the present embodiment, the second driving signal lines in the second display panel 120 include second scanning signal lines 122 and second data signal lines 124. Since the signal connection line 112 is connected to the first data signal line in the first display panel 110, when the first display panel 110 and the second display panel 120 are both in a display state, a parasitic capacitor C1 is formed between the second scan signal line 122 and the first driving signal line 114 in the second display panel 120, and a parasitic capacitor C2 is formed between the second data signal line 124 and the first driving signal line 114 in the second display panel 120.
In the present embodiment, the first display panel 110 is an AMOLED display panel, and the second display panel 120 is a PMOLED display panel. Specifically, the second display panel 120 includes a substrate, a first electrode layer, and a pixel defining layer. The first electrode layer is formed over the substrate. The pixel definition layer is formed on the first electrode layer. The signal connection line 112 is disposed below the pixel definition layer and avoids a region where a photosensitive device such as the camera head 930 is located. By disposing the signal connection line 112 below the pixel definition layer and avoiding the area where the camera is located, the interference of the signal connection line 112 to the light-emitting area and the normal operation of the camera can be avoided. It is understood that a corresponding insulating layer body is disposed between the signal connection line 112 and the first electrode layer to ensure that the two operate independently. The insulating layer body can be a newly added insulating layer or can directly utilize the existing layer body structure in the display panel.
In one embodiment, the signal connection line 112 is located between the first electrode layer and the substrate. That is, the signal connection line 112 is prepared before the first electrode layer. Also, the signal connection line 112 is disposed under the first electrode layer, so that an operational influence on the first electrode layer can be reduced. In this case, the first electrode layer is an anode layer. In another embodiment, the signal connection line 112 may also be disposed above the first electrode layer and below the pixel definition layer. When the signal connection line 112 is disposed above the first electrode layer, the first electrode layer is a cathode layer, so as to prevent the signal connection line 112 from interfering with its normal operation.
In an embodiment, the pixel definition layer of the first sub-display area AA22 may be made of an opaque material (e.g., a light-blocking or light-absorbing material), such as a black organic glue. Since the first sub-display area AA22 does not need to be provided with a camera, the requirement for light transmittance in this area is low. In this case, the signal connection line 112 is made of metal or transparent metal oxide. For example, when the signal connection line 112 employs a transparent metal oxide, Indium Tin Oxide (ITO), Indium Zinc Oxide (IZO), silver-doped indium tin oxide (Ag + ITO), silver-doped indium zinc oxide (Ag + IZO), or the like may be employed. The pixel definition layer 250 of the first sub-display area AA22 is made opaque to sacrifice a certain panel transmittance to ensure that the signal connection line 112 passing through the first sub-display area AA22 is invisible, thereby improving the visual effect of the display screen.
In an embodiment, the pixel defining layers of the second display area AA2 are all made of transparent materials. In this case, the signal connection line 112 is made of a transparent metal oxide material. By setting the pixel defining layer of the second display area AA2 to be a light-transmitting material, it is ensured that the display screen has a better light transmittance, and the normal operation of the photosensitive devices such as the camera 930 arranged below is ensured. When the signal connection line 112 is made of a transparent metal oxide, it is ensured that the transparency of the display panel is not affected when the second display panel 120 is a transparent display panel.
In one embodiment, the signal connection line 112 and the first electrode of the first electrode layer are disposed as wavy traces, as shown in fig. 4. Specifically, in the extending direction of the wavy routing wire, the width of the wavy routing wire changes continuously or discontinuously. The continuous width change means that the widths of any two adjacent positions on the wavy routing are different. The width discontinuous change means that the widths of two adjacent positions in a partial area on the signal trace are the same, and the widths of two adjacent positions in the partial area are different. By designing the first electrodes in the second display panel 120 and the signal connection lines 112 as wave-shaped traces, when external light passes through the signal traces, the positions of diffraction fringes generated at different positions of the signal traces are different. The diffraction fringes at different positions are mutually offset, so that the diffraction effect can be effectively weakened, and the photographed graph has higher definition when the camera is arranged below the second display panel 120.
In one embodiment, a pixel opening is formed in the pixel defining layer. Each pixel opening corresponds to a light emitting structure. The shape of each pixel opening can be circular, oval, dumbbell or gourd-shaped, and specifically refer to fig. 5. By arranging the sub-pixels to be circular, elliptical, dumbbell or gourd shaped, the diffraction effect can be also weakened. In addition, the area of each sub-pixel can be enlarged to the maximum extent by a round shape, an oval shape, a dumbbell shape or a gourd shape, and the light transmittance is further improved.
Generally, the voltages of the second data signal and the second scan signal in the PMOLED display panel are higher relative to the first data signal in the AMOLED display panel. Therefore, potential jumps of signals on the second data signal line and the second scan signal line of the PMOLED display panel may affect signal writing of the AMOLED display panel, thereby causing crosstalk. In this embodiment, the timing control circuit can control the potential transition points of the signals in the second driving signal lines in the second display panel 120, that is, the second scanning signals in the second scanning signal lines 122 and the second data signals in the second data signal lines 124, to respectively shift the signal writing time of the region where the first driving signal lines 114 are blocked.
Further, when the PMOLED display panel displays different gray-scale pictures, the pulse width of the first Data signal (Data) is changed, so that a plurality of pulse widths exist in the first Data signal of the PMOLED display panel, as shown in fig. 6. In fig. 6, the PM timing represents the timing of the PMOLED display panel, and the AM timing represents the timing of the AMOLED display panel. When the AMOLED display panel displays different gray-scale images, the AMOLED display panel is realized by changing the magnitude of the second data signal, which has only one pulse width, as shown in FIG. 6. The AM signal write timing in fig. 6 refers to the timing of the first data signal. Therefore, in this embodiment, the pulse widths of the first Data signal, the second Data signal and the second scan signal can be adjusted, and as a result of the adjustment, the potential transition points (i.e., the rising edge and the falling edge) of the Data signals with different pulse widths corresponding to each gray scale in the PMOLED display panel avoid the signal writing time (the low level in the timing sequence in fig. 6) of the AMOLED display panel. Meanwhile, since the cathode Scan signal (i.e., Scan cathode in fig. 6) in the PMOLED display panel also has many pulse widths, it needs to be adjusted so that both the rising edge and the falling edge avoid the signal writing time of the AMOLED display panel, as shown in fig. 6. The timing diagram of only the nth gray scale and the N +1 gray scale is shown in the PM timing sequence of FIG. 6. In the actual processing process, the potential transition points of the data signals corresponding to the 0-255 gray scales need to be kept away from the signal writing time of the region where the first driving signal line 114 is isolated. It is to be understood that fig. 6 is merely a timing diagram in one embodiment and is not to be construed as the only limitation of the present application.
In one embodiment, the first driving signal lines in the first display panel 110 include first scanning signal lines. The second driving signal lines in the second display panel 120 include second scanning signal lines. The first scanning signal line is used for transmitting a first scanning signal, and the second scanning signal line is used for transmitting a second scanning signal. The display screen further comprises a first scan driving circuit and a second scan driving circuit. The first scan driving circuit is used for providing a first scan signal to the first scan signal line. The second scanning driving circuit is used for providing a second scanning signal to the second scanning signal line. The time sequence control circuit is respectively connected with the first scanning driving circuit and the second scanning driving circuit. The time sequence control circuit is used for controlling the first scanning driving circuit and the second scanning driving circuit, so that the first scanning signal and the second scanning signal are synchronous, that is, the scanning processes of the first display area AA1 and the second display area AA2 are triggered by the trigger signal at the same time, thereby ensuring that the first display area AA1 and the second display area AA2 synchronously display corresponding contents, and realizing the integrated driving of the display screen. During scanning, the frequency of the first scanning signal and the frequency of the second scanning signal may be different, for example, the frequency of the first scanning signal is an integer multiple of the frequency of the second scanning signal, or the frequency of the second scanning signal is an integer multiple of the frequency of the first scanning signal, so that the scanning signals may be triggered at the same time, which is beneficial to synchronous display of pictures. In an embodiment, the first scan driving circuit and the second scan driving circuit may be implemented by different driving chips. In other embodiments, the first scan driver circuit and the second scan driver circuit may be integrated in the same driver chip. The first scanning driving chip, the second scanning driving chip and the time sequence control circuit are all arranged in a frame area (or a non-display area) of the display screen.
In one embodiment, the first display panel 110 is an AMOLED display panel, and the second display panel 120 is an AMOLED display panel or an AMOLED-like display panel. The AMOLED-like display panel is a structure in which the pixel circuit includes only one switching element (i.e., driving TFT) and has no capacitance. The other structures of the AMOLED-like display panel are the same as those of the AMOLED display panel. The second display panel 120 is described as an AMOLED-like display panel.
Fig. 7 is a cross-sectional view of an AMOLED-like display panel in an embodiment. Referring to fig. 7, the AMOLED display panel includes a substrate 810 and a pixel circuit 820 (i.e., a TFT array) disposed on the substrate 810. A first electrode layer is provided over the pixel circuit 820. The first electrode layer includes a plurality of first electrodes 830. The first electrodes 830 correspond to the pixel circuits 820 one to one. The first electrode 830 here is an anode. The AMOLED-like display panel further includes a pixel defining layer 840 disposed on the first electrode 830. The pixel defining layer 840 has a plurality of openings, and the light emitting structure layer 850 is disposed in the openings to form a plurality of sub-pixels, wherein the sub-pixels correspond to the first electrodes 830 one-to-one. A second electrode 860 is disposed above the light emitting structure layer 850, and the second electrode 860 is a cathode, which is a planar electrode, that is, a planar electrode formed of a planar electrode material. The pixel circuit 840 is provided with a scanning signal line, a data signal line, and a TFT switching element. The scanning signal line and the data signal line are connected to the TFT switching element. The scan signal line controls the switching on and off of the TFT switching elements, and the data signal line supplies a driving current to the first electrode 830 when the pixel is turned on, so as to control the sub-pixel to emit light.
In the present embodiment, the signal connection line 112 is disposed below the pixel definition layer 840 and below the pixel circuit, so that the two are spatially staggered from each other, thereby reducing crosstalk therebetween. In other embodiments, the signal connection line 112 is disposed under the pixel defining layer 840 and completed in the same process step as the conductive layer in the pixel defining layer 840, so that additional processes are not required during the manufacturing process, and the manufacturing complexity is not increased. In another embodiment, the signal connection line 112 is disposed under the pixel defining layer 840 and between the pixel circuit and the first electrode layer 830.
In one embodiment, the substrate 810 may be a rigid substrate, such as a transparent substrate like a glass substrate, a quartz substrate, or a plastic substrate; the substrate 810 may also be a flexible substrate, such as a PI film, to improve the transparency of the device. The optical structure layer 850 may be an OLED (Organic Light-Emitting Diode).
Fig. 8 is a circuit schematic of a pixel circuit 820 in an embodiment. Referring to fig. 8, unlike the pixel circuit of the conventional AMOLED display panel, the pixel circuit 820 includes only a switching device, and does not include a storage capacitor or the like, thereby forming a capacitor-less structure. In this embodiment, the pixel circuit 820 includes one switching device. The switching devices are disposed in one-to-one correspondence with the first electrodes 630, i.e., one sub-pixel corresponds to one switching device. The switching device comprises a first terminal 2a, a second terminal 2b and a control terminal 2c, as will be described in detail later. 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 fig. 8. In the pixel circuit 820, the data signal line is connected to the first end 2a of the switching element, and the scanning signal line is connected to the control end 2c of the switching element, so that the number of the switching elements in the pixel circuit 820 can be reduced to one, and the load current of the scanning signal line and the load current of the data signal line can be greatly reduced.
The scanning signal lines in the display panel control the pixel circuits 820 to be turned on and off, only the switching voltage required by the switching elements in the pixel circuits 820 is needed to be provided, the current of the light-emitting structures (OLED) is not needed to be input, the load current of the scanning signal lines is greatly reduced, and the scanning signal lines can be made of transparent materials such as ITO (indium tin oxide). When the pixel circuit 820 is turned on, the data signal line supplies a driving current to the anode to control the sub-pixels to emit light, and the data signal line only needs to supply the driving current of one sub-pixel at each moment, so that the load of the data signal line is small. Therefore, the data signal lines can also be made of transparent materials such as ITO and the like, so that the light transmittance of the display screen is improved. The multiple sub-pixels share the surface electrode (cathode), the current of the sub-pixels in one row at each moment is provided by the whole surface cathode, the requirement on the conductivity of the cathode is greatly reduced, the high-transparency electrode can be adopted, the transparency is improved, the integral consistency of the screen is improved, and the negative photoresist is not needed to separate the cathode.
In an embodiment, the first electrode 830 may be arranged in a circular shape, an oval shape, a dumbbell shape, or a gourd shape, and particularly, refer to fig. 5. By arranging the first electrode 830 in a circular, elliptical, dumbbell or gourd shape, the diffraction effect can be also weakened. In an embodiment, the shape of the pixel openings in the pixel defining layer 640 is circular, elliptical, dumbbell, or gourd-shaped, as in fig. 5, so that the diffraction effect can be weakened as well. In an embodiment, the signal lines such as the scan signal lines and the data signal lines can adopt the wavy trace shown in fig. 4, so as to achieve the effect of improving diffraction.
In this embodiment, the materials and arrangement of the pixel defining layer 840 and the signal connection lines 112 may be as those in the foregoing embodiments, which are not described herein.
In one 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 materials of each layer having good light transmittance. For example, each structural film layer is made of a material having a light transmittance of greater than 90%, so that the light transmittance of the entire display panel can be greater than 70%. Furthermore, each structural film layer is made of a material with the light transmittance of more than 95%, so that the light transmittance of the display panel is further improved, and even the light transmittance of the whole display panel is over 80%. Specifically, the conductive traces may be ITO, IZO, Ag + ITO, Ag + IZO, or the like, and the insulating layer material is preferably SiO2，SiNxAnd Al2O3And the pixel definition layer adopts a high-transparency material.
It is understood that the transparency of the second display panel 120 can also be achieved by other technical means. The transparent or semi-transparent and semi-reflective display panel can normally display pictures when in a working state, and when the display panel is in other functional requirement states, external light can penetrate through the display panel to irradiate a photosensitive device and the like arranged below the display panel.
By providing the second display panel 120 as a transparent or transflective display panel, a light sensing device such as a camera can be provided below the second display panel 120. It can be understood that when the photosensitive device does not operate, the second display area AA2 may normally perform dynamic or static image display, and when the photosensitive device operates, the second display area AA2 changes with changes in the display content of the entire display screen, such as displaying an external image being photographed, or the second display area AA2 may also be in a non-display state, so as to further ensure that the photosensitive device can perform light collection through the second display panel 120 of the second display area AA 2. In other embodiments, the light transmittances of the first display area AA1 and the second display area AA2 may 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 screen has a better light transmittance uniformity, and the display screen has a better display effect.
An embodiment of the application further provides a display terminal. Fig. 9 is a schematic structural diagram of a display terminal in an embodiment. The display terminal includes an apparatus body 910 and a display 920. The display 920 is disposed on the apparatus body 910 and is connected to the apparatus body 910. The display 920 may adopt the display in any of the foregoing embodiments to display static or dynamic pictures.
Fig. 10 is a schematic structural diagram of an apparatus body 910 in an embodiment. In this embodiment, the device body 910 may have a slotted region 912 and a non-slotted region 914. Photosensitive devices such as cameras 930 and light sensors may be disposed in the slotted region 912. At this time, the second display area AA2 of the display 920 is attached to the slotted area 914, so that the above-mentioned photosensitive devices such as the camera 930 and the optical sensor can collect external light through the second display area AA 2.
In an embodiment, since the second display panel 120 in the second display area AA2 can effectively improve the diffraction phenomenon generated by the external light transmitted through the second display area AA2, the quality of the image captured by the camera 930 on the display terminal can be effectively improved, the distortion of the captured image due to diffraction can be avoided, and the accuracy and sensitivity of the optical sensor for sensing the external light can be improved.
The display terminal can be a digital device such as a mobile phone, a tablet, a palm computer and an ipod.
