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.
To address the above issues, the skilled person has developed a display screen, which realizes the full-screen display of the electronic device by setting a transparent display panel in the slotted area. However, the display effect of the two regions may be different due to the difference between the driving modes and the device structures of the display panel in the slotted region and the display panel in the other display region, thereby affecting the display effect of the display screen. For example, when the slotted region adopts a pmaaoled display panel, and the other regions (i.e., the non-slotted region) are AMOLED display panels, the AMOLED pixel structure is generally a PenTile structure, such as an RGBG (red, green, blue, and green sub-pixels) side-by-side structure (as shown in fig. 1), and the full-color display is implemented by matching with an SPR (sub pixel Rendering) algorithm. The driving method of the PMOLED display panel is an RGB driving method and does not support the SPR algorithm. Generally, in order to meet the PMOLED driving requirement, the PMOLED display panel must have an RGB pixel structure, and thus a G position is sacrificed in the PMOLED region, which results in too large difference between the display effect of the PMOLED display panel and the display effect of the AMOLED display panel, poor display effect of the whole display screen, and influence on the visual appearance.
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. 2 is a schematic structural diagram of a display screen in an embodiment. Referring to fig. 2, 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. 2. In other embodiments, the second display area AA2 may be disposed on one side of the display screen, and the first display area AA1 may be disposed on the other side of the display screen. For example, the second display area AA2 and the first display area AA1 are sequentially distributed along the length direction of the display screen, or sequentially distributed along the width direction of the display screen. At this time, only one side of the first display area AA1 and the second display area AA2 is connected. In fig. 2, 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.
The pixel arrangement of the first display area AA1 has a first minimum repeating unit. The first minimal repeating unit is also a pixel unit. The first minimal repeating unit comprises a plurality of sub-pixels, and at least two sub-pixels have the same color. The pixel arrangement of the second display area AA2 has a second minimal repeating unit. The second minimal repeating unit has the same number of sub-pixels as the first minimal repeating unit. For example, when the first minimal repeating unit has four sub-pixels, the second minimal repeating unit also has four sub-pixels. The same-color sub-pixels in the second minimal repeating unit are electrically connected with each other and are driven synchronously.
The display panel has the first display area AA1 and the second display area AA2 for displaying a dynamic or static screen image, and can realize full-screen display. The first display area AA1 has a first minimal repeating unit, and the second display area AA2 has a second minimal repeating unit, so that the second display area can be normally driven by electrically connecting the same color sub-pixels in the second minimal repeating unit to each other, thereby realizing normal display of the display screen.
In one embodiment, the display screen includes a first display panel 110 and a second display panel 120. The first display panel 110 is disposed on the first display area AA1, and the second display panel 120 is disposed on 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. Specifically, the first display panel 110 is an AMOLED display panel, and the second display panel 120 is a PMOLED display panel. The pixel arrangement of the first display panel 110 has a first minimum repeating unit, and the pixel arrangement of the second display panel 120 has a second minimum repeating unit.
In one embodiment, the second minimal repeating unit and the first minimal repeating unit have the same area and the same number of sub-pixels, and the sub-pixels of the same color in the second minimal repeating unit are electrically connected with each other to form a sub-pixel unit. The area referred to herein refers to the area of the projection of the smallest repeating unit (i.e., pixel unit) on the substrate. The same color sub-pixels in the second minimum repeating unit are electrically connected with each other, so that the second display panel 120 can be driven by the existing driving mode and has the same pixel arrangement mode as the first display panel 110, the pixel density of the first display panel 110 is the same as that of the second display panel 120, the pixel density of the whole display screen at each position is consistent, and a better display effect is achieved. In this case, the same pixel arrangement means that the number and the position arrangement of the pixels in the minimum repeating unit are the same, but the sub-pixels at the same position are not required to have the same color. In another embodiment, the area of the second minimum repeating unit is greater than the area of the first minimum repeating unit, such that the PPI of the second display panel 120 is less than the PPI of the first display panel 110. For example, the area of each sub-pixel in the second minimal repeating unit is larger than the area of each sub-pixel in the first minimal repeating unit, so that the area of the second minimal repeating unit is larger than the area of the first minimal repeating unit. In other embodiments, the area of each sub-pixel in the second minimal repeating unit is equal to the area of the first minimal sub-pixel, but the pitch between each sub-pixel of the second minimal repeating unit is greater than the pitch of each sub-pixel in the first minimal sub-pixel.
In one embodiment, the same color sub-pixels in the second minimal repeating unit are connected by conductive lines to be driven as a sub-pixel unit, so that the existing RGB driving requirements can be satisfied. Specifically, the second display panel 120 includes a substrate, an anode formed on the substrate, a light emitting structure formed on the anode, and a cathode formed on the light emitting structure. The conductive line is used to connect the anodes, or the cathodes, of the same color subpixels in the second minimal repeating unit. In other embodiments, the conductive lines may also include an anode conductive line and a cathode conductive line. The anode conducting wire is connected with the anode of the same-color sub-pixel, and the cathode conducting wire is connected with the cathode of the same-color sub-pixel. When the conductive line is used to connect the anodes of the same color subpixels in the second minimal repeating unit, the conductive line is completed in the same process step as the anodes. When the conductive line is used to connect the cathodes of the same color subpixels in the second minimal repeating unit, the conductive line and the cathodes are completed in the same process step, thereby simplifying the manufacturing process. In one embodiment, the conductive line may be made of the same material as the anode and the cathode, for example, the conductive line may be a metal or a transparent metal oxide. For example, when the conductive line 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. When the conductive lines are made of transparent metal oxide, it is ensured that the second display panel 120 does not affect the transparency of the display panel when it is a transparent display panel.
In one embodiment, the first display panel 110 has a pixel structure as shown in fig. 1. At this time, the first minimal repeating unit has a structure as shown in fig. 3, and includes a red sub-pixel R, a green sub-pixel G, a blue sub-pixel B, and a green sub-pixel B, which are sequentially arranged. In one embodiment, the second minimal repeating unit of the second display panel 120 has a structure as shown in fig. 4. In the present embodiment, the second minimal repeating unit and the first minimal repeating unit have the same pixel structure. In this case, the same pixel structure means that the number of pixels in the minimum repeating unit and the position arrangement of each sub-pixel are the same, that is, the sub-pixels at the same position have the same color. At this time, the two green subpixels G in the second minimal repeating unit are physically connected by the conductive line 10, thereby matching the RGB driving method of the second display panel. Because the luminous efficiency of the green sub-pixel G is higher, the brightness of the whole display screen can be improved by arranging the two green sub-pixels G. In an embodiment, the positions of the red sub-pixel R and the blue sub-pixel B may be interchanged to form another sub-pixel arrangement rule.
In the present embodiment, the conductive line 10 is disposed at a first end of the anode or the cathode of the corresponding sub-pixel. The conductive line 10 also serves as a connection line to be connected to the drive circuit. At this time, two identical green sub-pixels G are separated by the blue sub-pixel B, and thus, the connection line 20 (for connection with the driving circuit) of the blue sub-pixel B is disposed at the second end. The second end is located at the opposite end of the electrode to the first end, thereby avoiding the possibility of overlapping the two and ensuring that both can be driven independently of each other.
Fig. 5 is a schematic structural diagram of a second minimal repeating unit in another embodiment. In this embodiment, the number of sub-pixels in the second minimal repeating unit is the same as the number and position arrangement of the sub-pixels in the first minimal repeating unit in fig. 3, but the specific arrangement rule of the sub-pixels is different. Specifically, in the present embodiment, two blue subpixels B are included in the second minimal repeating unit. In fig. 5, the second minimal repeating unit includes a red subpixel R, a blue subpixel B, a green subpixel G, and a blue subpixel B, which are sequentially arranged. By providing two blue subpixels B and connecting the two blue subpixels B, the driving manner of the second display panel can be matched. Moreover, because the luminous efficiency of the blue sub-pixel B is lower than that of the green sub-pixel G, and the luminance is quickly attenuated, the service life and the luminance of the blue sub-pixel can be prolonged by arranging the two blue sub-pixels B, so that the service life and the luminance of the whole display screen are prolonged. In another embodiment, the positions of the red and green sub-pixels R and G may be interchanged.
Fig. 6 is a schematic structural diagram of a second minimal repeating unit in yet another embodiment. In this embodiment, the number of sub-pixels in the second minimal repeating unit is the same as the number and position arrangement of the sub-pixels in the first minimal repeating unit in fig. 3, but the specific arrangement rule of the sub-pixels is different. Specifically, in the present embodiment, the second minimal repeating unit includes two red subpixels R. In fig. 5, the second minimal repeating unit includes a red subpixel R, a green subpixel G, a red subpixel R, and a blue subpixel B, which are sequentially arranged. By providing two red sub-pixels R and connecting the two red sub-pixels RB, the driving manner of the second display panel can be matched. In addition, because the light emitting efficiency of the two red sub-pixels R is between that of the green sub-pixel G and that of the blue sub-pixel B, and the luminance is attenuated quickly, the service life and the luminance of the red sub-pixels can be prolonged by arranging the two red sub-pixels R, and the service life and the luminance of the whole display screen are prolonged. In one embodiment, the positions of the blue sub-pixel B and the green sub-pixel G may be interchanged.
It is understood that in other embodiments, the first minimal repeating unit may adopt other pixel structures, and in this case, the number of the sub-pixels of at least another color in the second minimal repeating unit may be more than two. In one embodiment, the same color sub-pixels in the second minimal repeating unit may be spaced apart by other color sub-pixels to achieve a more uniform display effect.
In one embodiment, the second minimal repeating unit serves as a minimal light emitting unit of the second display panel 120. The display screen further comprises a driving circuit. In this embodiment, the sub-pixel having two or more sub-pixels of the same color in the minimum light emitting unit is referred to as a first sub-pixel. The driving circuit is further used for adjusting the lighting time or the driving current of the first sub-pixel, and can also adjust the lighting time and the driving current at the same time, so that the display brightness of the first sub-pixel is consistent with the display brightness of other sub-pixels, the brightness consistency of the whole display screen is ensured, and the display effect is good.
In one embodiment of the present invention, the substrate is,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 transparent functional 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 more than 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 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, at least one of the anode and the cathode of the second display panel 120 is a wave-shaped trace, as shown in fig. 7. 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. 7.
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. 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. Since the first display panel 110 and the second display panel 120 of the display 920 have the same pixel density (PPI), it is ensured that the display 920 has better display uniformity.
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.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
