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. In general, the data signals of each display panel need to be provided by separate data signal lines, which increases the number of wires and the risk of crosstalk between the data signal lines in the display panel in the slotted area and the display panel in the non-slotted area, thereby causing the problem that the signals in the display panel cannot be written normally and display is abnormal.
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. The second display area AA2 may also be disposed in the left middle area or the right middle area of the first display area AA 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 display panel includes a first display panel 110, a second display panel 120, a first scan driving unit 132, a second scan driving unit (not shown), a data driving unit 140, and a control unit (not shown). The first display panel 110 is located in the first display area AA1, and the second display panel 120 is located 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 area AA1 has a plurality of first scanning signal lines 112 and a plurality of data signal lines 114 disposed therein. The data signal lines 114 and the first scanning signal lines 112 are arranged to intersect in their extending directions and define pixel units at the intersection positions. The number of the first scanning signal lines 112 and the data signal lines 114 may be set according to the pixel distribution of the first display panel. Only a part of the data signal lines 114 and a part of the first scan signal lines 112 are drawn in fig. 1. The second display area AA2 has a second scan signal line 122 disposed therein. In the present embodiment, a portion of the data signal lines 114 in the first display area AA1 extends into the second display area AA2, thereby defining pixel cells arranged to intersect the extending direction of each of the second scan signal lines 122. That is, the data signal line 114 serves as both the data signal line of the first display area AA1 and the second display area AA2, and may simultaneously supply data signals to the first display area AA1 and the second display area AA 2. The number of data signal lines may be reduced by sharing the data signal lines 114, thereby reducing the risk of crosstalk between the first and second display areas AA1 and AA 1.
The first scan driving circuit 130 is connected to each of the first scan signal lines 112. The first scan driving circuit 130 is used for providing a first scan signal to each of the first scan signal lines 112. The second scanning driving circuit is connected to each of the second scanning signal lines 122. The second scan driving circuit is used to provide a second scan signal to each scan signal line 122. The data driving circuit 140 is connected to each data signal line 114 to supply a data signal to each data signal line 114. In the embodiment, the second display area AA2 and the first display area AA1 share data signal lines, so when the data driving circuit 140 provides data signals to the first display area AA1, signals are also provided to the second display area AA 2. At this time, the display control of the first display area AA1 and the second display area AA2 needs to be implemented by a control circuit. Specifically, the control circuit is used to control the data driving circuit 140 to supply the data signals to the first display area AA1 and the second display area AA2, that is, to the data signal line 114. The control circuit is also used for controlling the second scan driving circuit to supply the second scan signal to the second scan signal line 122 when the first scan driving circuit 130 does not supply the first scan signal to the first scan signal line 112, so that the normal display of the display screen can be ensured under the condition of sharing the data signal lines.
In the present embodiment, the second display area AA2 is located at the top middle area of the first display area AA 1. The first scan driving circuit is disposed in a frame area of the first display area AA 1. The data driving circuit 140 is disposed on a surface of the first display area AA1 away from the second display area AA2, i.e., a bottom surface. It is to be understood that the above-described position arrangement is merely illustrative in one embodiment, and that other arrangements may be used. In one embodiment, the first scan driving circuits 130 include at least two scan driving circuits, which are respectively disposed on two sides of the first display panel 110 to synchronously drive the first display areas AA1 from two sides.
In one embodiment, the first scan driving circuit 130 includes a plurality of first scan driving units 132 and a plurality of idle scan driving units 134. Each first scan driving unit 132 and each idle scan driving unit 134 are arranged in cascade. After cascade connection, the output of the previous stage is used as the input of the next stage, thereby realizing the progressive scanning of the display scheme. Each of the first scan driving units 132 is connected to one of the first scan signal lines 112 to supply a first scan signal thereto. Therefore, the number of the first scan driving units 132 is the same as the number of the first scan signal lines 112. The number of the idle scan driving units 134 is the same as the number of the second scan signal lines 122. The idle scan driving unit 134 is not connected to the first scan signal line 112, and is not connected to other signal lines. Therefore, when the signal is transmitted to the idle scan driving unit 134, it does not output the scan signal to the outside, but only outputs the scan signal from the output terminal as the input signal of the next scan driving unit. Therefore, in the present embodiment, when the control circuit detects that no signal is output from the first scan driving unit 132, that is, the signal is transmitted to the idle scan driving unit 134, the control circuit controls the second scan driving unit to provide the second scan signal to the second scan signal line 122. At this time, since the idle scan driving unit 134 is not connected to the first scan signal line 112, the first data signal is not present in the first scan signal line 112, and the signal writing switch of the first display panel 110 is turned off, so that the normal display of both the first display panel 110 and the second display panel 120 can be ensured. In one embodiment, the first scan driving unit 132 and the idle scan driving unit 134 are both shift register units.
In an embodiment, the idle scan driving unit 134 is arranged at intervals among the plurality of first scan driving units 132, and may be disposed at equal intervals, for example. For example, after several first scan driving units 132 are provided, one empty scan driving unit 134 is provided. By disposing the idle scan driving units 134 between the first scan driving units 132 at intervals, it is equivalent to empty one or more rows of signal writing time during the driving of the two first scan driving units 132, and the signal writing time is used as the signal writing time of the second scan driving circuit, thereby ensuring the normal display of the display panel. FIG. 2 is a timing diagram of an embodiment. In this embodiment, the first display panel is an AMOLED (AM) display panel, and the second display panel is a PMOLED (PM). In fig. 2, the 1 st stage and the 2 nd stage … … n each represent the timing of a drive signal, and Data represents the timing of a Data signal. In an embodiment, the first scan driving unit 132 and the second scan driving unit are integrated on the substrate of the first display area AA1 by a gate-in-panel (GIP) technology, and are located in the border area. The borderless display can be better realized by the GIP technique.
In an embodiment, the control circuit is further configured to control the first scan driving circuit and the second scan driving circuit, so that the first scan signal and the second scan signal are synchronized, 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 display corresponding contents synchronously, and implementing 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 scan driving circuit, the second scan driving circuit, the data driving circuit and the control circuit are all disposed 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 a PMOLED display panel. 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%. In particular toThe conductive traces can be made of ITO, IZO, Ag + ITO or Ag + IZO, and the insulating layer is preferably made of 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.
In an embodiment, the conductive traces in the second display panel 120, such as the second scan signal lines and the data signal lines, extending to the second display area AA2 are wavy traces, as shown in fig. 3. 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 conductive trace are the same, and the widths of two adjacent positions in the partial area are different. The conductive traces in the second display panel 120 are designed as wave-shaped traces, so that when external light passes through the conductive traces, the positions of diffraction fringes generated at different positions of the conductive 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 an embodiment, the conductive traces in the first display panel 110 can also be designed as wavy traces, as shown in fig. 3.
In one embodiment, the sub-pixel shape of the second display panel 120 is a circle, an ellipse, a dumbbell, or a gourd-shaped. That is, the pixel defining layer in the second display area AA2 has a pixel opening formed therein. 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. 4. 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. An embodiment of the application further provides a display terminal. Fig. 5 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. 6 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.
