Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a display device and an electronic device. Background Art

[0002] With the development of communication technology, electronic devices such as smart phones are becoming more and more popular. During the use of electronic devices, the electronic devices can use their display screens to display images. In order to achieve better display effects and user experience, the size of the display screen is getting larger and larger. However, when the display screen of an electronic device exceeds a certain size, it is difficult to hold. Therefore, it is becoming increasingly important to increase the screen-to-body ratio of the display screen.

[0003] In the related art, a camera is set on the back of the display device, and the display device is provided with a light-transmitting channel such as a notch or an opening corresponding to the camera. The camera is used to obtain an image of the external light signal passing through the light-transmitting channel, and the light-transmitting channel occupies the area of ​​the display surface of the display device. Summary of the invention

[0004] Embodiments of the present application provide a display device and an electronic device, which can increase the screen-to-body ratio of the electronic device.

[0005] An embodiment of the present application provides a display device, including a first display area and a second display area, and the display device further includes:

[0006] A display layer, the display layer comprising a plurality of first pixels arranged in the first display area and a plurality of second pixels arranged in the second display area;

[0007] a first driving layer, the first driving layer comprising a first driving unit disposed in the second display area, the first driving unit being used to drive the first pixel; and

[0008] a second driving layer, the second driving layer comprising a second driving unit arranged in the second display area, the second driving unit being used to drive the second pixel, the second driving layer being provided with a plurality of via holes penetrating the second driving layer in a thickness direction of the second driving layer, and at least a part of the plurality of via holes being located in the second display area, the via holes being used to pass a signal line through so as to electrically connect the first driving unit and the first pixel;

[0009] The display layer, the second driving layer and the first driving layer are stacked.

[0010] An embodiment of the present application further provides an electronic device, which includes a display device and a functional device. The display device is the display device described above, and the functional device is used to transmit an optical signal through the first display area.

[0011] In the embodiment of the present application, the first driving unit for driving the first pixel and the second driving unit for driving the second pixel are both arranged in the second display area, so that the first display area does not need to be provided with a driving unit, which can reduce the arrangement of the shading device and the wiring, thereby improving the light transmittance of the first display area. Therefore, the functional device can directly transmit the optical signal through the first display area, and the transmission of the optical signal can be achieved without opening a hole in the display device. While maintaining the integrity of the entire display area of ​​the display device, the screen-to-body ratio of the electronic device can also be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The embodiment of the present application provides an electronic device and a display device thereof. The electronic device may include a display device and a camera. The camera may be installed below the display device, that is, the camera may capture images through the display device. It is understandable that the transmittance of a conventional display device is low, and the effect of the camera capturing images through the display device is not good. To this end, the embodiment of the present application may set the display device to be partitioned, such as setting the transmittance of the camera portion of the display device to be greater than the transmittance of other positions of the display device, which can improve the effect of the camera capturing images. The technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application.

[0034] See also Figure 1 , Figure 1 A first structural diagram of an electronic device provided for an embodiment of the present application. The electronic device 10 may be a computing device such as a laptop computer, a computer monitor including an embedded computer, a tablet computer, a cellular phone, a media player, or other handheld or portable electronic devices, a smaller device (such as a wristwatch device, a hanging device, a headset or earpiece device, a device embedded in glasses or other devices worn on the user's head, or other wearable or miniature devices), a television, a computer display that does not include an embedded computer, a gaming device, a navigation device, an embedded system (such as a system in which an electronic device with a display is installed in an information kiosk or a car), a device that implements the functions of two or more of these devices, or other electronic devices. Figure 1 In the exemplary configuration of FIG. 1 , the electronic device 10 is a portable device such as a cellular phone, a media player, a tablet computer, or other portable computing device. Other configurations may be used for the electronic device 10 if desired. Figure 1 This is exemplary only.

[0035] It should be understood that the "plurality" mentioned herein refers to two or more than two.

[0036] Please continue reading Figure 1 The electronic device 10 includes a display device 20, and the display device 20 can display a picture. The display device 20 can be an organic light-emitting diode display device 20 (Organic Light-Emitting Diode, OLED). The display surface of the display device 20 can have a larger display area and a narrower non-display area, or the display device 20 has a narrower black border. Of course, the display surface of the display device 20 can also be a display area without a non-display area, that is, the display device 20 can be a full screen. A display device cover layer such as a transparent glass layer, a light-transmitting plastic, sapphire, or other transparent dielectric layer can be used to protect the display device 20.

[0037] The display device 20 may be in a regular shape, such as a rectangle, a rounded rectangle or a circle. Of course, in some other possible embodiments, the display device 20 may also be in an irregular shape, which is not limited in the present embodiment.

[0038] See also Figure 2 , Figure 2 for Figure 1The display device 20 may include a first display area 240 and a second display area 220, both of which may display images, and the first display area 240 and the second display area 220 may display the same image or different images.

[0039] The first display area 240 and the second display area 220 may be adjacent to each other, for example, the periphery of the first display area 240 is surrounded by the second display area 220. For another example, a portion of the first display area 240 is surrounded by the second display area 220, that is, the first display area 240 is located at the end face position or the end face connection position of the display device 20. It can be understood that the end face connection position of the display device 20 is the position where the two end faces of the display device 20 are connected to each other, which may include a portion of the two end faces connected to each other. It should be noted that the first display area 240 may be one or more. When there are more than one first display area 240, the multiple first display areas 240 may be located at the same end face of the display device 20, or at multiple end faces of the display device 20, or at multiple end face connection positions of the display device 20. Or a portion of the multiple first display areas 240 is located at the end face connection position of the display device 20, and a portion is located at the end face position of the display device 20.

[0040] In the embodiment of the present application, the display area of ​​the second display area 220 can be set to be larger than the display area of ​​the first display area 240. The second display area 220 can be used as the main display area of ​​the display device 20, and the first display area 240 can be used as the auxiliary display area, or the functional display area, of the display device 20. For example, the light transmittance of the first display area 240 can be set to be larger than the light transmittance of the second display area 220. Therefore, the light transmittance of the first display area 240 can be greatly improved in the non-display state of the first display area 240, and the functional devices of the electronic device 100, such as the camera 60, sensors and other devices, can be set in the first display area 240 to improve the quality of signal transmission of the camera 60, sensors and other devices through the first display area 240.

[0041] It should be noted that, in some embodiments, the display area of ​​the first display area 240 can be set to be the same as the display area of ​​the second display area 220, or the display area of ​​the first display area 240 can be set larger than the display area of ​​the second display area 220.

[0042] In the embodiment of the present application, a camera 60, a sensor and other functional devices can be set at a position corresponding to the first display area 240, such as below the first display area 240. When the first display area 240 is in a non-display state, the camera 60, the sensor and other functional devices can transmit signals to the first display area 240, such as collecting images. At the same time, the first display area 240 can also display images as required to achieve the integrity of the display device 20 and the integrity of the display area. Not only can the hidden design of the camera 60, the sensor and other functional devices be achieved, but also the screen ratio of the electronic device 10 can be increased.

[0043] It should be noted that the positions of the functional devices of the electronic device 10, such as the camera 60 and the sensor, are not limited to being below the first display area 240, and can also be set away from the first display area 240. A light guide column can be set between the functional devices, such as the camera 60 and the sensor, and the first display area 240 to achieve signal transmission. Among them, the light guide column can transmit the light signal emitted by the functional devices such as the camera 60 and the sensor to the first display area 240, and transmit it through the first display area 240 to the outside of the electronic device 10. The light guide column can also transmit the external light signal of the transparent first display area 240 to the functional devices such as the camera 60 and the sensor. The light guide column can be a cylindrical structure or a multi-segment structure. When the light guide column is a multi-segment structure, it can have at least one light guiding surface to achieve reflection of the light signal.

[0044] In order to set the transmittance of the first display area 240 to be greater than the transmittance of the second display area 220, the embodiment of the present application can set the driving unit such as a thin film transistor (TFT) driving the first display area 240 in the display device 20 outside the first display area 240. For example, it is set in the driving layer structure driving the second display area 220 in the display device 20, or at the side or periphery of the display device 20, or in the non-display area of ​​the display device 20. For another example, a double-layer driving layer structure is set in the display device 20, and the driving unit such as a TFT driving the first display area 240 is set in the driving layer structure corresponding to the second display area 220 by means of a via.

[0045] See also Figure 3 , Figure 3 for Figure 2 The display device 20 is a cross-sectional view along the P2-P2 direction. The display device 20 may include an upper substrate 250, a display layer 210, a driving layer 230 and a lower substrate 270 stacked in sequence. The display device 20 can drive the display layer 210 through the driving layer 230 to display the picture. Among them, the upper substrate 250 and the lower substrate 270 can both be made of transparent materials, such as transparent glass. Among them, the lower substrate 270 can be defined as a first substrate, and the upper substrate 250 can be used as a second substrate.

[0046] See also Figure 4 , Figure 4 for Figure 2 The display layer 210 may include a plurality of pixels, wherein the display layer 210 includes a second display portion 212 located in the second display area 220 and a first display portion 214 located in the first display area 240, that is, the display layer 210 may include a plurality of second pixels located in the second display area 220 and a first display portion 214 located in the first display area 240.

[0047] Multiple first pixels in the first display area 240. Multiple second pixels and multiple first pixels can be arranged in an array. The arrangement of the first pixels 242 in the first display area 240 can be one of the standard RGB arrangement, Pentile arrangement or Delta arrangement, and the arrangement of the second pixels 222 in the second display area 220 can be one of the standard RGB arrangement, Pentile arrangement or Delta arrangement. It should be noted that the first pixels 242 in the first display area 240 can also be arranged in other ways, and the second pixels 222 in the second display area 220 can also be arranged in other ways.

[0048] It can be understood that the first display portion 214 and the second display portion 212 are merely limitations on the location of the display layer 210.

[0049] The first display portion 214 may include pixels, and the second display portion 212 may also include pixels. The first display portion 214 and the second display portion 212 both have the same function as a display layer.

[0050] In order to further improve the light transmittance of the first display area 240, the embodiment of the present application can use a light-transmitting material for the first pixels of the first display area 240. Of course, in some other embodiments, the arrangement of the plurality of first pixels can be made more sparse than that of the second pixels, that is, the distribution density of the first pixels can be made smaller than that of the second pixels.

[0051] The driving layer 230 may include a plurality of driving units, each of which may drive at least one pixel. The driving layer 230 may include a plurality of first driving units for driving the first display area 240 and a plurality of second driving units for driving the second display area 220. Each first driving unit may be electrically connected to a first pixel and may drive a first pixel. Each second driving unit may be electrically connected to a second pixel and may drive a second pixel. The driving layer 230 may include a second driving unit 232 located in the second display area 220 and a first driving unit 234 located in the first display area 240, a plurality of second driving units may be arranged in the second driving unit 232, and a plurality of first driving units may be arranged in the first driving unit 234.

[0052] Among them, the driving unit can adopt one of the driving circuits such as 2T1C, 5T1C, 7T1C, etc. For example, the first driving unit can adopt one of 2T1C, 5T1C, 7T1C, and the second driving unit can adopt one of 2T1C, 5T1C, 7T1C. Among them, T represents a thin film transistor, and C represents a capacitor. In order to improve the transmittance of the first display area 240, the first driving unit arranged in the first display area 240 can be a driving circuit that is simpler than the main driving unit of the second display area 220, for example, the number of thin film transistors included in the first driving unit is less than the number of thin film transistors in the second driving unit. For example, the first driving unit can adopt one of 2T1C, 5T1C, and the second driving unit adopts 7T1C. The number of opaque thin film transistors in the first driving unit is smaller, and the opaque part in the first display area 240 is smaller, which can improve the transmittance of the first display area 240.

[0053] The physical structure of the second pixel 242 of the second display area 220 and the first pixel 222 of the first display area 240 can be set to be the same, or the second display area 220 and the first display area 240 can have the same pixel physical structure. For example, the size of the second pixel 222 is the same as the size of the first pixel 242, and the arrangement of the second pixel 222 is the same as the arrangement of the first pixel 242. They can be molded in the same process. It should be noted that the physical structure of the second pixel 222 of the second display area 220 and the first pixel 242 of the first display area 240 can also be set to be different. For example, the size of the second pixel is larger than the size of the first pixel, and the arrangement density of the second pixel is greater than the arrangement density of the first pixel. It should be noted that, Figure 4 Only some pixels of the display device 20 are shown, and Figure 4 The area formed by the arrangement of the first pixels 242 shown in FIG. 1 is substantially the same in size as the area formed by the arrangement of the second pixels 222 .

[0054] The first display area 240 may have a plurality of first pixel sets 244, each of which may include a plurality of first pixels 242 connected in parallel, or a plurality of first pixels 242 connected in parallel may form a first pixel set 244. One of the first pixel sets 244 may include at least two first pixels 242, and the colors of at least two first pixels 242 in a first pixel set 244 may be the same, such as red pixels. The colors of at least two first pixels 242 in a first pixel set 244 may also be different, such as red pixels and green pixels. The plurality of first pixels 242 in a first pixel set 244 may be connected together by a plurality of signal lines, and the signal lines may be made of light-transmitting materials.

[0055] See also Figure 5 , Figure 5 for Figure 2 Another partial schematic diagram of the display device is shown. Figure 5 A plurality of second driving units 224 of the second display area 220 and a plurality of first driving units 246 of the first display area 240 are shown. One of the second driving units 224 can be electrically connected to a second pixel 222, and one second driving unit 224 can drive one second pixel 222. Each of the first pixel sets 244 can be electrically connected to a first driving unit 246, and one first driving unit 246 can drive a first pixel set 244, that is, one first driving unit 246 can drive all first pixels 242 in a first pixel set 244. Compared with one driving unit driving one pixel, the embodiment of the present application can reduce the number of first driving units. The embodiment of the present application can set the first driving unit 246 in the first display area 240, such as in the first driving part 234. Since the driving of multiple first pixels 242 in the first display area 240 can be achieved by using fewer first driving units 246, the light transmittance of the first display area 240 can be improved. It should be noted that, Figure 5 Only part of the second driving unit 224 and part of the first driving unit 246 of the display device 20 are shown, and Figure 5 The area formed by the arrangement of the first driving units 246 shown in FIG. 1 is substantially the same in size as the area formed by the arrangement of the second driving units 224 .

[0056] In the embodiment of the present application, a first pixel set 244 may be used as a first display unit of the first display area 240, that is, the smallest unit of the display screen of the first display area 240. For example, the first pixel set 244 as a first display unit includes four first pixels 242 of the same color, or sixteen first pixels 242 of the same color. For another example, the first pixel set 244 as a first display unit includes a plurality of first pixels 242 of different colors. Among them, the plurality of second pixels 222 of the second display area 220 can form a second display unit, or a second pixel unit, such as the second pixel unit of the second display area 220 includes a red pixel, a green pixel and a blue pixel. Of course, the second pixel unit of the second display area 220 may also include other pixels, such as a white pixel or a yellow pixel.

[0057] In the embodiment of the present application, multiple first pixel sets 244 can also be used as a first display unit, for example, three first pixel sets 244 can be used as a first display unit, and for example, four first pixel sets 244 can be used as a light-transmitting display unit. A first pixel set 244 in a first display unit may include four first pixels 242 of the same color or sixteen first pixels 242 of the same color. For example, a first display unit includes three first pixel sets 244, one of the three first pixel sets 244 includes four red pixels, another first pixel set 244 includes four green pixels, and the third first pixel set 244 includes four blue pixels.

[0058] See also Figure 6 , Figure 6 for Figure 2 A schematic diagram of a first arrangement of a first display unit in a first display area in a display device is shown. A first display unit 216a in a first display area 240 may include three first pixel sets 244, which may be a first pixel set 244a, a first pixel set 244b, and a first pixel set 244c. The first pixel set 244a may include four red pixels 242 (R), the first pixel set 244b may include four green pixels 242 (G), and the first pixel set 244c may include four blue pixels 242 (B). It should be noted that the arrangement of multiple first pixel sets in a first display unit is not limited to this.

[0059] See also Figure 7 , Figure 7 for Figure 2 A schematic diagram of a second arrangement of a first display unit in a first display area of ​​a display device is shown. A first display unit 216b in a first display area 240 may include three first pixel sets 244, which may be a first pixel set 244d, a first pixel set 244e, and a first pixel set 244f. The first pixel set 244d may include four red pixels 242, the first pixel set 244e may include four green pixels 242, and the first pixel set 244f may include four blue pixels 242.

[0060] See also Figure 8 , Figure 8 for Figure 2A third arrangement schematic diagram of a first display unit in the first display area of ​​the display device is shown. A first display unit 216c in the first display area 240 may include three first pixel sets 244, which may be a first pixel set 244h, a first pixel set 244i, and a first pixel set 244j. The first pixel set 244h may include four red pixels 242, the first pixel set 244i may include four green pixels 242, and the first pixel set 244j may include four blue pixels 242.

[0061] See also Fig. 9 , Fig. 9 for Figure 2 A fourth arrangement schematic diagram of a first display unit in the first display area of ​​the display device is shown. A first display unit 216d in the first display area 240 may include three first pixel sets 244, which may be a first pixel set 244k, a first pixel set 244m, and a first pixel set 244n. The first pixel set 244k may include four red pixels 242, the first pixel set 244m may include four green pixels 242, and the first pixel set 244n may include four blue pixels 242.

[0062] It can be understood that when a first display unit of the first display area 240 includes four first pixel sets 244, the first pixels 242 included in each of the four first pixel sets 244 are the same color, such as one first pixel set 244 includes a plurality of red pixels, a second first pixel set 244 includes a plurality of green pixels, a third first pixel set 244 includes a plurality of blue pixels, a fourth first pixel set 244 includes a plurality of white pixels, or a fourth first pixel set 244 includes a plurality of yellow pixels.

[0063] in Figures 6 to 9 Only several arrangements of a first display unit in the first display area 240 of the display device 20 are shown. Other arrangements of a first display unit in the first display area 240 of the embodiment of the present application are also possible.

[0064] It should be noted that in some schemes, in order to improve the transmittance of the first display area, the size of the first pixel in the first display area can be set larger than the second pixel in the second display area, and the arrangement of the first pixel in the first display area can be made sparser than the arrangement of the second pixel in the second display area. Thus, the first pixel in the first display area and the second pixel in the second display area have different pixel physical structures. In the actual process, since the first pixel in the first display area and the second pixel in the second display area have different pixel physical structures, different masks (or masks) are required to form pixel structures through a series of processes such as exposure, development, and cleaning. For example, the first pixel in the first display area needs to be formed by a first group of processes using a first type of mask, and the second pixel in the second display area needs to be formed by a second group of processes using a second type of mask. Not only do additional masks and tools need to be required, but the process will also be increased, the processing cost and complexity will increase, and the pixel yield after molding will be reduced.

[0065] In order to save tools and process, the first pixel of the first display area and the second pixel of the second display area can be formed by the same process, the same mask and other tools, so that the first pixel of the first display area and the second pixel of the second display area have the same pixel physical structure. However, if the first pixel of the first display area and the second pixel of the second display area have the same pixel physical structure, and the first pixel of the first display area and the second pixel of the second display area are driven in the same way, too many wirings and first driving units will be arranged in the first display area, and too many wirings will affect the light transmittance of the first display area.

[0066] Based on the relevant scheme, in order to solve the process and process cost, and at the same time reduce the arrangement of signal lines in the first display area, so as to facilitate the arrangement of lines in the first display area and improve the transmittance of the first display area, the embodiment of the present application connects at least two pixels in the first display area in parallel to form a first pixel group. After being connected in parallel, multiple first pixels can be connected to the same signal line, which can greatly save the number of signal lines compared to each first pixel being connected to a signal line, facilitate the arrangement of signal lines, and at the same time improve the transmittance of the first display area.

[0067] Therefore, the embodiment of the present application can change the wiring at the display layer position of the first display area to greatly reduce the number of signal lines arranged at the first display area position without changing the physical structure of the pixels of the entire display device by connecting at least two first pixels in the first display area in parallel to form a first pixel group, thereby improving the transmittance of the first display area.

[0068] In order to further improve the transmittance of the first display area 240, a part of all the first driving units for driving the first display area 240 can be set in the first display area 240, and the other part can be set in other positions, such as the second display area 220, such as a part of the first driving units are set in the first driving part 234, and the other part is set in the second driving part 232.

[0069] Of course, in the embodiment of the present application, all the first driving units for driving the first display area 240 may also be arranged at other locations, such as all the first driving units are arranged in the second display area 220 .

[0070] It should be noted that if the first driving unit 246 used to drive the first pixel 242 in the first display area 240 is arranged in the second display area 220, such as the second driving unit 232, it is necessary to arrange the wiring. Considering that the wiring will occupy the space at the connection position of the first display area 240 and the second display area 220, if there are too many lines, there may not be enough space for arrangement, and the thickness needs to be increased to arrange more lines. In order not to increase the thickness of the wiring position additionally and to ensure that there is enough space for wiring at the connection position of the first display area 240 and the second display area 220, at least two first pixels 242 in the first display area 240 can be connected in parallel to form a first pixel set 244 and then connected to the same signal line, which can greatly reduce the number of signal lines and reduce the occupation of space by signal lines, and can realize that the first driving unit 246 used to drive the first pixel 242 in the first display area 240 is set in the second display area 220.

[0071] However, considering that the second display area 220 is the main display part of the display device 20. If all the first driving units 246 used to drive the first display area 240 are set in the second display area 220, it will affect the setting of the second driving part 232 located in the second display area 240, and will affect the wiring process of the second driving part 232, which may affect the quality and effect of the display image in the second display area 220. To this end, in order to reduce the impact of the first driving unit 246 on the second display area 220, the embodiment of the present application can set a third display area between the second display area 220 and the first display area 240, and a transition can be formed to arrange the first driving unit in the third display area, thereby reducing the impact of the first driving unit 246 on the second display area 220.

[0072] See also Fig.10 , Fig.10Another structural schematic diagram of the display device provided in the embodiment of the present application. The display device 20 may also include a third display area 260, which may also be referred to as a transition area. The third display area 260 may connect the second display area 220 and the first display area 240, and the third display area 260 may be connected between the second display area 220 and the first display area 240. The third display area 260 of the embodiment of the present application may separate the second display area 220 and the first display area 240 without being directly connected. The third display area 260 of the embodiment of the present application may also connect the second display area 220 and a part of the first display area 240, and the second display area 220 and another part of the first display area 240 may also be directly connected. The size of the third display area 260 may be much smaller than the size of the second display area 220, and the first display area 240 and the third display area 260 may jointly form an auxiliary display area of ​​the display device 20, where the first display area 240 and the third display area 260 may be defined as auxiliary display areas, or auxiliary display areas.

[0073] See also Fig.11 , Fig.11 for Fig.10 The display device shown is a cross-sectional view along the P6-P6 direction. The display layer 210 may also include a third display unit 216 located in the third display area 260. The third display unit 216 may be arranged with a plurality of third pixels, and the arrangement of the third pixels may be one of the standard RGB arrangement, the Pentile arrangement or the Delta arrangement. Of course, the third pixels may also be arranged in other ways. The driving layer 230 may also include a third driving unit 236, and the third driving unit 236 may be provided with a plurality of driving units, such as the third driving unit 236 is provided with a plurality of third driving units, a third driving unit may be electrically connected to a third pixel, and a third driving unit may drive a third pixel. The third driving unit may adopt one of 2T1C, 5T1C, and 7T1C. For example, the third driving unit adopts 5T1C, and the third display area 260 of the embodiment of the present application may adopt 5T1C, the first display area 240 may adopt 2T1C, and the second display area 220 may adopt 7T1C. Therefore, the quality of the image displayed in the second display area 220 can be higher than that in the third display area 260 , and the quality of the image displayed in the third display area 260 can be higher than that in the first display area 240 , so that a transition can be achieved between the first display area 240 and the second display area 220 .

[0074] Of course, the driving modes of the first display area 240, the second display area 220 and the third display area 260 are not limited thereto. For example, the first display area 240 and the third display area 260 both adopt 5T1C, and the second display area 220 adopts 7T1C.

[0075] See also Fig.12 , Fig.12 for Fig.10 A first partial schematic diagram of the display device shown. The arrangement of the third pixels 262 of the third display area 260 may be the same as the arrangement of the second pixels 224 of the second display area 220, and may also be the same as the arrangement of the first pixels 242 of the first display area 240. For example, the second display area 220, the third display area 260 and the first display area 240 have the same physical structure of pixels, and the pixels of the second display area 220, the third display area 260 and the first display area 240 may be formed in the same process. It should be noted that the arrangement of the third pixels 262 of the third display area 260 may also be different from the arrangement of the second pixels 224 of the second display area 220 or the first pixels 242 of the first display area 240. It should be noted that, Fig.11 Only some pixels of the display device 20 are shown, and Fig.11 The area formed by the arrangement of the first pixels 242, the area formed by the arrangement of the third pixels 262, and the area formed by the arrangement of the second pixels 222 are substantially the same in size.

[0076] In the embodiment of the present application, all the first driving units for driving the first display area 240 can be arranged in the third display area 260, such as arranging the first driving units in the third display part 236. The driving layer structure of the first display area 240 can be made without the first driving unit, such as the first driving part 234 of the first display area 240 without the thin film transistor, which can greatly improve the light transmittance of the first display area 240. At the same time, other problems caused by arranging the first driving unit in the first display area 240 can be avoided, such as the diffraction problem caused by the periodically arranged first driving units to the imaging of the camera 60, and the stray light problem caused by the reflection and refraction of the first driving unit to the imaging of the camera 60.

[0077] It should be noted that, since the third display area 260 is provided with a plurality of third driving units, the plurality of third driving units will occupy the space of the third driving part 236. In the present application, the first driving unit is provided in the third driving part 236, which will also occupy the space of the third driving part 236, and the wiring will also occupy the space of the third driving part 236. In order to ensure that the first driving unit can be provided in the third driving part 236, the wiring of the third driving part 236 can be provided thinner to reduce the space occupied by a single signal line to accommodate the arrangement of more signal lines.

[0078] Of course, in the embodiment of the present application, the first driving unit can be disposed in the third driving unit 236 without changing the thickness of the wiring in the third driving unit 236 and the wiring can be satisfied.

[0079] Please continue reading Fig.12, a plurality of third pixel sets 264 may be provided in the third display area 260, each of the third pixel sets 264 may include at least two third pixels 262 connected in parallel, which may include at least two third pixels 262 of the same color, such as red pixels. A third pixel set 264 may also include at least two third pixels 262 of different colors, such as red pixels and green pixels. A plurality of third pixels 262 in a third pixel set 264 may be connected together through a plurality of signal lines. The number of third pixels 262 in a third pixel set 264 may be greater than the number of first pixels 242 in a first pixel set 244, for example, a third pixel set 264 includes four third pixels 262, and a first pixel set 244 includes sixteen first pixels 242. Of course, the number of third pixels 262 in a third pixel set 264 may be the same as the number of first pixels 242 in a first pixel set 244.

[0080] In the embodiment of the present application, a third pixel set 264 can be used as a third display unit of the third display area 260. For example, the third pixel set 264 as a third display unit includes two third pixels 262 of the same color, or four third pixels 262 of the same color. For another example, the third pixel set 264 as a third display unit includes a plurality of third pixels 262 of different colors.

[0081] In the embodiment of the present application, multiple third pixel sets 264 can also be used as a third display unit, for example, three third pixel sets 264 can be used as a third display unit, and for example, four third pixel sets 264 can be used as a third display unit. A third pixel set 264 in the third display unit can include two third pixels 262 of the same color or four third pixels 262 of the same color. For example, a third display unit includes three third pixel sets 264, one of the three third pixel sets 264 includes four red pixels, another third pixel set 264 includes four green pixels, and the third third pixel set 264 includes four blue pixels. For the number of third pixel sets 264 included in the third display unit and the arrangement of the third pixels 262 in the third display unit, please refer to Figures 6 to 9 The structure of the first display unit shown is not repeated here.

[0082] It can be understood that when a third display unit of the third display area 260 includes four third pixel sets 264, the third pixels 262 included in each of the four third pixel sets 264 are the same color, such as one third pixel set 264 includes a plurality of red pixels, the second third pixel set 264 includes a plurality of green pixels, the third third pixel set 264 includes a plurality of blue pixels, the fourth third pixel set 264 includes a plurality of white pixels, or the fourth third pixel set 264 includes a plurality of yellow pixels.

[0083] See also Fig.13 , Fig.13 for Fig.10 A second partial schematic diagram of the display device is shown. Fig.13 2 shows a plurality of second driving units 224 of the second display area 220, a plurality of third driving units 266 of the third display area 260, and a plurality of first pixel units 246. The second driving unit 224 can refer to Figure 5 The contents shown are not repeated here. The plurality of third driving units 266 and the plurality of second display units 246 are located in the third display area 260 , such as being arranged in the third driving part 236 .

[0084] A plurality of third driving units 266 are used to drive the third display area 260. Each third driving unit 266 can be electrically connected to a third pixel set 264. A third driving unit 266 can drive a third pixel set 264, that is, a third driving unit 266 can drive all third pixels 262 in a third pixel set 264. Compared with one driving unit driving one pixel, the embodiment of the present application can reduce the number of third driving units, thereby reducing the occupation of the third driving unit 236 space, and the first driving unit 246 can be set. For example, a third pixel set 264 includes four third pixels 262 connected in parallel, and a third driving unit 266 can occupy a space corresponding to a third pixel 262, or a space slightly smaller than the space corresponding to the third pixel 262. Therefore, a third pixel set 264 can leave space corresponding to at least three third pixels 262, and a plurality of first pixel units 264 can be set in the free space, such as three first driving units 246. The three remaining third pixels 262 may be arranged in a one-to-one correspondence with the three first driving units 246 .

[0085] Therefore, in the embodiment of the present application, at least two third pixels 262 in the third display area 260 can be connected in parallel to form a third pixel set 264, a third driving unit 266 can be used to drive a plurality of third pixels 262, and sufficient space can be reserved in the third driving unit 236 to set the first driving unit 246. Thus, it is possible to set the light-proof thin film transistor in the first display area 240 to the third display area 260 that does not need to collect signals through light such as a camera, and the size of the third display area 260 can be set smaller, and the first display area 240 and the second display area 220 are connected. When the display image in the second display area 220 is not greatly affected, the deterioration of the quality of the display image in the third display area 260 will not have a great impact on the display effect of the entire display device 20.

[0086] In addition, the number of third pixels 262 connected in parallel in the third display area 260 may be smaller than the number of first pixels 242 connected in parallel in the first display area 240 , which may make the display transition between the first display area 240 and the second display area 220 smoother.

[0087] It should be noted that the location of the first drive unit in the embodiment of the present application is not limited to the third display area 260. For example, a part of the first drive unit is set in the third display area 260, and another part of the first drive unit is set in the first display area 240, or another part of the first drive unit is set in the third display area 260, and another part of the first drive unit is set in the second display area 220, or the first drive unit is divided into three parts and respectively set in the first display area 240, the third display area 260, and the second display area 220.

[0088] It should also be noted that the location of the first driving unit in the embodiment of the present application is not limited to the display area, and the first driving unit may also be disposed on the side or non-display area of ​​the display device 20 .

[0089] See also Fig.14 , Fig.14 for Fig.10The third partial schematic diagram of the display device shown. The display device 20 may also include a non-display area 280, and the first driving unit 246 that drives the first display area 240 may be arranged in the non-display area 280. The display device 20 may be a full screen, that is, the front of the display device 20 is basically the display area, and the front of the display device 20 is basically equivalent to the display surface of the electronic device when viewed from the front of the electronic device. However, even if it is a full-screen display device 20, there will still be a non-display area 280 at the edge of the display device 20. The non-display area 280 can be understood as a black border of the display device 20, and the width of the black border can be very narrow, such as a black border width of less than 1 mm or 0.5 mm. Because the first display area 240 is small in area, the number of first pixels in the first display area 240 is relatively small, and multiple first pixels in the first display area 240 can be connected in parallel, the number of first driving units 246 driving the first display area 240 is reduced, and the first driving unit 246 can be set to the black edge position, which can improve the light transmittance of the first display area 240 without affecting the second display area 220 or the third display area 260. Multiple first driving units 246 need to be set corresponding to the first pixels of the first display area 240, and all the first driving units 246 can be set at the black edge position.

[0090] In order to better accommodate all the first drive units 246 at the black border position, a simpler first drive unit 246 can be used. For example, the first drive unit 246 can use a 2T1C, 5T1C or other drive circuit, so that the number of thin film transistors in each first drive unit 246 is small, and a single first drive unit 246 requires less space. The first pixel distribution density in the first display area 240 can also be set lower, and the total number of first drive units 246 used to drive the first display area 240 is small. It should be noted that a portion of the multiple first drive units 246 can also be set in the non-display area 280, and a portion can be set in other positions, such as the first display area 240 or the third display area 260.

[0091] It should be noted that the manner in which the transmittance of the first display area 240 is increased in the embodiment of the present application is not limited thereto, and other manners may also be used. For example, the wiring of the display device 20 in the first display area 240 may be arranged as a transparent structure to increase the transmittance of the first display area 240. For another example, no polarizing structure may be arranged at the position of the first display area 240. For another example, the driving unit that drives the first display area 240 may be driven passively, which may greatly reduce the components in the wiring and driving unit. It is understandable that the schemes of increasing the transmittance of the material and changing the arrangement of the wiring to increase the transmittance of the first display area 240 are all within the scope of the present application.

[0092] The second display area 220 in the embodiment of the present application may be an active-type drive (AMOLED) display area, and the first display area 240 may be an active-type drive display area or a passive-type drive (PMOLED) display area. In the embodiment of the present application, the first display area 240 may be set smaller than the second display area 220, so that the display content of the first display area 240 is less than that of the second display area 220, and the importance of the content displayed in the first display area 240 is lower than that of the second display area 220. Therefore, in the embodiment of the present application, the second display area 220 adopts AMOLED to ensure that the main display area of ​​the display device 20 can have a higher display effect. At the same time, the first display area 240 adopts PMOLED, and the passively driven first display area 240 only needs one thin film transistor to drive, and the number of opaque thin film transistors is small, which can greatly improve the light transmittance of the first display area 240. Moreover, the area displayed by the first display area 240 can be much smaller than the area displayed by the second display area 220. If the quality of the display image of the first display area 240 is reduced, it will not have a significant impact on the entire display of the display device 20. It should be noted that the first display area 240 may also be actively driven, so that the display effect of the first display area 240 can be close to the display effect of the second display area 220 .

[0093] The third display area 260 of the embodiment of the present application can select an actively driven display area or a passively driven display area as needed. Because the third pixel 262 of the third display area 260 and the first pixel 242 of the first display area 240 have the same physical structure, the third display area 260 and the first display area 240 can be driven in the same manner, such as the third display area 260 and the first display area 240 can be passively driven display areas. If the area of ​​the third display area 260 is large, or in order to improve the display quality of the third display area 260, the third display area 260 and the second display area 220 can use the same driving display area, such as both can be actively driven display areas.

[0094] The size and shape of the first pixel 242 in the first display area 240 can be set as needed. For example, the first pixel 242 can be rectangular or quasi-circular. The quasi-circular first pixel 242 can be circular, elliptical, or rounded rectangular. The quasi-circular first pixel 242 can improve the diffraction problem of the first display area 240 because the edge is an arc transition.

[0095] In the embodiment of the present application, the functional components of the electronic device 10, such as the camera 60 and the sensor, can be arranged inside the display device 20. For example, the lens of the camera 60 faces the lower substrate 270 of the display device 20, and the camera 60 is arranged corresponding to the first display area 240, or the camera 60 is located below the lower substrate 270 at the position of the first display area 240. The camera 60 can obtain the external light signal passing through the first display area 240 for imaging. In the embodiment of the present application, the lens of the camera 60 and the lower substrate 270 can be arranged at intervals. Of course, the lens of the camera 60 can also share the lower substrate 270, for example, the position of the lower substrate 270 corresponding to the first display area 240 is set to an arc structure.

[0096] In order to reduce the space of the electronic device 10 occupied by the camera 60, the lens of the camera 60 can be close to or adjacent to the lower substrate 270 of the display device 20. The lower substrate 270 of the display device 20 is mainly used to support other layer structures of the display device 20 and does not need any special functions.

[0097] See also Fig.15 , Fig.15 The first structural diagram of the display device and the camera in the electronic device provided by the embodiment of the present application. In order to further reduce the occupation of the internal space of the electronic device 10 by the camera 60, a first mounting hole 272 can be set on the lower substrate 270 relative to the camera 60, and the camera 60 can be at least partially set in the first mounting hole 272. The first mounting hole 272 can be a blind hole, that is, the thickness of the part of the lower substrate 270 relative to the camera 60 is less than the thickness of the other parts. The lower substrate 270 is still a complete substrate, which does not affect its function of carrying other layer structures of the display device 20, and can vacate some space to accommodate the camera 60. The installation method of the first mounting hole 272 and the camera 60 can be set according to the size of the first mounting hole 272 and the size of the camera 60. For example, if the space of the first mounting hole 272 is not enough to install the entire camera 60, the lens part of the camera 60 can be set in the first mounting hole 272. If the camera is small enough, the entire camera 60 can be set in the first mounting hole 272.

[0098] It should be noted that the camera can be replaced by other functional components of the electronic device 10 such as a sensor, that is, at least a part of the sensor of the electronic device 10 can be set in the first mounting hole 272.

[0099] See also Fig.16 , Fig.16A second structural diagram of the display device and the camera in the electronic device provided in the embodiment of the present application. Because the driving layer 230 of the first display area 240 may not be provided with a first driving unit, the camera 60 may be installed in the driving layer. Specifically, the first mounting hole 272 opened on the lower substrate 270 is a through hole, and the driving layer of the first display area 240 has a second mounting hole 238 relative to the camera 60, the first mounting hole 272 and the second mounting hole 238 are connected, and the camera 60 may be at least partially located in the second mounting hole 238. For example, the lens of the camera 60 is located in the first mounting hole 272 and the second mounting hole 238. The second mounting hole 238 may be a through hole or a blind hole. The first mounting hole 272 and the second mounting hole 238 may be made after the partial stacking structure of the display device 20 is formed. For example, after the driving layer 230 and the display layer 210 of the display device 20 are arranged on the lower substrate 270, the first mounting hole 272 and the second mounting hole 238 are made corresponding to the lens position of the camera 60 by laser or the like.

[0100] It should be noted that the camera can be replaced with other functional components of the electronic device 10 such as a sensor, that is, at least a part of the sensor of the electronic device 10 can be set in the first mounting hole 272 and the second mounting hole 238.

[0101] It is understandable that the camera 60 relative to the first display area 240 can be used as the front camera of the electronic device. The front camera is generally a camera whose lens cannot be moved. The lower substrate and the driving layer of the display device 20 can be provided with a first mounting hole and a second mounting hole. Then the camera 60 relative to the first display area 240 can be a camera with a movable lens. The movable lens of the camera 60 is used to realize functions such as auto focus. It should be noted that the camera 60 can also be a rear camera, that is, the electronic device 10 can be provided with two opposite display devices 20.

[0102] One camera 60 or multiple cameras 60 may be disposed below the first display area 240. The multiple cameras 60 may be cameras 60 that cooperate with each other, such as two identical cameras, a normal camera and a blur camera or a black and white camera, etc. In addition to the camera, other functional devices may be disposed below the first display area 240, such as a proximity sensor, a light sensor, a distance sensor, a fingerprint recognition sensor, etc.

[0103] The method of improving the transmittance of the first display area 240 in the embodiment of the present application can also adopt a multi-layer drive layer method, such as setting two layers of drive layers in the display device, setting the first drive unit for driving the first display area in one of the drive layers, and away from the first display area. And the second drive unit for driving the second display area is set in another drive layer, and away from the first display area. In this way, the drive units corresponding to the first display area can be set at a position away from the first display area, which can greatly improve the transmittance of the first display area. The scheme of improving the transmittance of the first display area by using two layers of drive layers is described in detail below in conjunction with the accompanying drawings.

[0104] See also Fig.17 , Fig.17 for Figure 2 The display device 20 is a cross-sectional view along the P4-P4 direction. The display device 20 may include an upper substrate 250, a display layer 210, a second drive layer 230, a first drive layer 290, and a lower substrate 270 stacked in sequence. The display device 20 can drive the display layer 210 through the first drive layer 290 and the second drive layer 230 to display a picture. Fig.17 The display layer 210 shown can be referred to as Figure 3 The display layer 210 shown, Fig.17 The upper substrate 250 shown can be referred to as Figure 3 The upper substrate 250 shown, Fig.17 The lower substrate 270 shown can be referred to as Figure 3 The lower substrate 270 is shown and will not be described in detail here.

[0105] in Fig.17 The second driving layer 230 shown may include a second light-transmitting portion 234 and a second driving portion 232. The second driving portion 232 may be provided with a plurality of second driving units, and the second driving unit provided in the second driving portion 232 may drive the second pixel in the second display area 220. The second driving portion 232 may be provided in the second display area 220, or the second driving portion 232 may be provided corresponding to the second display portion 212, such as the second driving portion 232 and the second display portion 212 are provided in a stacked manner. It should be noted that the second light-transmitting portion 234 and the second driving portion 232 are limitations on the position of the second driving layer 230, and the second driving layer 230 may not only be provided with driving units, but also may be provided with circuits.

[0106] At least a portion of the second light-transmitting portion 234 may be disposed in the first display area 240. For example, the second light-transmitting portion 234 is disposed in the first display area 240, or the second light-transmitting portion 234 may be disposed corresponding to the first display portion 214, such as the second light-transmitting portion 234 and the first display portion 214 are stacked. The second light-transmitting portion 234 may not be provided with a driving unit to increase the transmittance of the second light-transmitting portion 234, thereby increasing the transmittance of the first display area 240. In some embodiments, the size of the second light-transmitting portion 234 is the same as the size of the first display portion 214, and the second light-transmitting portion 234 overlaps with the first display portion 214 in a direction perpendicular to the display device 20, or the projection of the second light-transmitting portion 234 on the display layer 210 overlaps with the projection of the first display portion 214 on the display layer 210. Of course, the size of the first display portion 214 may be slightly smaller than the size of the second light-transmitting portion 234, such as the projection of the first display portion 214 on the display layer 210 is located inside the projection of the second light-transmitting portion 234 on the display layer 210. In the embodiment of the present application, the size of the first display portion 214 is set to be smaller than or equal to the size of the second light-transmitting portion 234, which can ensure that the portion of the second driving layer 230 corresponding to the first display portion 214 has no driving unit, and can ensure that the light transmittance of the first display area 240 is improved.

[0107] It should be noted that a portion of the second light-transmissive portion 234 may be disposed corresponding to the second display portion 212 , as long as the portion of the second driving layer 230 disposed corresponding to the first display portion 214 has no driving unit.

[0108] Please continue reading Fig.17 The second driving layer 230 is provided with a plurality of via holes 2322, and the plurality of via holes 2322 penetrates the second driving layer 230 in the thickness direction of the second driving layer 230. One or more signal lines can be arranged in each via hole 2322. The via hole 2322 can be arranged in the second driving part 232, but not in the position of the second light-transmitting part 234, so as to ensure that the second light-transmitting part 234 has no driving circuit, and reduce the wiring of the second light-transmitting part 234, or do not wire at the position of the second light-transmitting part 234.

[0109] in Fig.17The first driving layer 290 shown may include a first driving part 292 and a first light-transmitting part 294. The first driving part 292 may be provided with a plurality of first driving units, and the first driving unit provided with the first driving part 292 may drive the first pixel in the first display area 240. The first driving part 292 may be provided in the second display area 220, or the first driving part 292 may be provided corresponding to the second display part 212, such as the first driving part 292, the second driving part 232 and the second display part 212 are provided in a stacked manner in sequence. It should be noted that the first driving part 292 and the first light-transmitting part 294 are limitations on the position of the first driving layer 290, and the first driving part 292 may not only be provided with driving units, but also may be provided with circuits.

[0110] At least a portion of the first light-transmitting portion 294 may be disposed in the first display area 240. For example, the first light-transmitting portion 294 is disposed in the first display area 240, or the first light-transmitting portion 294 may be disposed corresponding to the first display portion 214, such as the first light-transmitting portion 294, the second light-transmitting portion 234 and the first display portion 214 are stacked in sequence. The first light-transmitting portion 294 may not be provided with a driving unit to increase the transmittance of the first light-transmitting portion 294, and thus the transmittance of the first display area 240 may be increased. In some embodiments, the size of the first light-transmitting portion 294 is the same as the size of the first display portion 214, and the first light-transmitting portion 294 overlaps with the first display portion 214 in a direction perpendicular to the display layer 210, or the projection of the first light-transmitting portion 294 on the display layer 210 overlaps with the projection of the first display portion 214 on the display layer 210. Of course, the size of the first display portion 214 may be slightly smaller than the size of the first light-transmitting portion 294, such as the projection of the first display portion 214 on the display layer 210 is located inside the projection of the first light-transmitting portion 294 on the display layer 210. In the embodiment of the present application, the size of the first display portion 214 is set to be smaller than or equal to the size of the first light-transmitting portion 294, which can ensure that the portion of the first driving layer 290 corresponding to the first display portion 214 has no driving unit, and can ensure that the light transmittance of the first display area 240 is improved.

[0111] It should be noted that a portion of the first light-transmissive portion 294 may be disposed corresponding to the second display portion 212 , as long as the portion of the first driving layer 290 corresponding to the first display portion 214 has no driving unit.

[0112] It should also be noted that the second light-transmitting portion 234 of the embodiment of the present application is located between the first light-transmitting portion 294 and the first display portion 214, and the sizes of the first light-transmitting portion 294, the second light-transmitting portion 234 and the first display portion 214 can be set to be the same and overlap each other. Of course, the size relationship between the first light-transmitting portion 294, the second light-transmitting portion 234 and the first display portion 214 is not limited to this, such as the sizes of the first light-transmitting portion 294, the second light-transmitting portion 234 and the first display portion 214 are reduced in sequence. For another example, the size of the first light-transmitting portion 294 is smaller than the size of the second light-transmitting portion 234 and the first display portion 214, and the size of the second light-transmitting portion 234 is the same as the size of the first display portion 214. For another example, the size of the first light-transmitting portion 294 is the same as the size of the second light-transmitting portion 234, and the size of the first light-transmitting portion 294 and the second light-transmitting portion 234 is smaller than the size of the first display portion 214.

[0113] In the embodiment of the present application, a signal line can be inserted into the via hole 2322, and the signal line can electrically connect the first pixel of the first display area 240 with the first driving unit of the first driving layer 290. For example, the signal line can electrically connect the first pixel of the first display portion 214 with the first driving unit of the first driving portion 290, so that the first driving unit in the first driving portion 290 can drive the first pixel. The first pixel can refer to the above first pixel 242, and the first driving unit can drive the above first driving unit 246, which will not be repeated here.

[0114] Among them, one end of the signal line can be electrically connected to the first pixel of the first display area 240, and the signal line electrically connected to the first pixel can be arranged to the second display area 220, pass through the via 2322 in the second display area 220, and the other end of the signal line can be electrically connected to the first driving unit of the second display area 240. For example, one end of the signal line is electrically connected to the first pixel of the first display part 214, and the signal line can be arranged from the second light-transmissive part 234 to the second driving part 232, pass through the via 2322 at the position of the second driving part 232, and pass through the via 2322 to the first driving part 292 to be electrically connected to the first driving unit of the first driving part 292. In this way, the first driving unit is not arranged in the first display area 214, but the driving of the first pixel in the first display area 214 is realized. It should be noted that in the actual wiring process, the arrangement of the first pixels can be more sparse than that of the second pixels, or the size of the first pixels can be set larger than that of the second pixels, or multiple first pixels can be connected in parallel, so as to greatly reduce the number of signal lines to meet the arrangement of the signal lines in the second light-transmitting portion 234 and pass through the via 2322.

[0115] It can be seen from this that the embodiments of the present application Fig.17The display device 20 shown can arrange the driving units in the second display area 220 by providing two driving layers, and does not provide the driving units in the first display area 240 , so as to improve the light transmittance of the first display area 240 .

[0116] Among them, multiple vias 2322 can be all arranged in the second driving part 232, and can be arranged around the second light-transmitting part 234, such as multiple vias 2322 are arranged around the second light-transmitting part 234 at equal intervals. In the embodiment of the present application, multiple vias 2322 are arranged around the second light-transmitting part 234. Compared with concentrating multiple vias 2322 in a certain position, the vias 2322 can be dispersedly arranged, which not only makes it easy to arrange the lines, but also reduces the length of the signal line. It should be noted that the internal space of the display device 20 is limited. Arranging multiple vias in the same position will occupy additional space in the second driving layer 230, affecting the arrangement of the internal wiring of the second driving layer 230. The present application arranges multiple vias 2322 at intervals to reduce the influence of the vias 2322 on the internal wiring arrangement of the second driving layer 230, which is easier to implement.

[0117] It is understandable that if the via 2322 is provided in the second driving part 232, the second driving part 232 will be provided with a plurality of second driving units, and the plurality of second driving units will occupy the space of the second driving part 232, while the free space of the second driving part 232 is limited. Therefore, the embodiment of the present application may provide the via 2322 between a plurality of adjacent second driving units. For example, one, two or three vias 2322 are provided between four adjacent second driving units. It should be noted that it is also possible to provide the via 2322 between the thin film transistors of each second driving unit.

[0118] In order to further improve the light transmittance of the first display area 240, the size of the first pixel in the first display area 240 can be set to be larger than the size of the second pixel in the second display area 220, such as the size of the first pixel is four times or sixteen times the size of the second pixel. Thus, the number of first pixels in the first display portion 214 can be reduced, and the number of wirings and first driving units in the first display portion 214 can be reduced, which not only makes it easier to connect the first pixel of the first display portion 214 with the signal line, and the signal line passes through the via 2322 to connect with the first driving unit, but also reduces the wiring in the first display portion 214, and the light transmittance of the first display area 240 can be further improved.

[0119] It should be noted that the arrangement and size of the first pixels in the first display area 214 and the arrangement and size of the second pixels in the second display area 212 may be the same, that is, the first display area 214 and the second display area 212 may have the same pixel physical structure. If the first display area 214 and the second display area 212 may have the same pixel physical structure, the first pixels in the first display area 214 and the second pixels in the second display area 212 may be specifically referred to in Figures 4 to 9 The corresponding contents are not repeated here. For example, sixteen first pixels in the first display area 214 are connected in parallel to form a first pixel set, a first pixel set can be electrically connected to a first driving unit, the colors of the sixteen first pixels in a first pixel set can be the same, three first pixel sets can form a display unit of the first display area 214, the first pixel in a first pixel set can be a red pixel, the first pixel in a first pixel set can be a green pixel, and the first pixel in a first pixel set can be a blue pixel. In this way, the number of first driving units can be reduced, and the number of vias 2322 can be reduced, and the wiring in the first display area 240, or in other words, the wiring in the first display part 214 can be reduced. Not only is it easier to connect the first pixel of the first display part 214 to the signal line, the signal line passes through the via 2322 to connect to the first driving unit, but also the wiring in the first display part 214 can be reduced, and the light transmittance of the first display area 240 can be further improved.

[0120] Therefore, if the embodiment of the present application cooperates with the display device 20 and optical devices such as the camera 60 or the sensor, it is easier to realize the transmission of optical signals through the first display area 240 of the transparent display device 20 by the camera 60 or the sensor.

[0121] It can be understood that since neither the first light-transmitting portion 294 nor the second light-transmitting portion 234 is provided with a driving unit, functional components of the electronic device 10 can be provided in the first light-transmitting portion 294 and the second light-transmitting portion 234 .

[0122] See also Fig.18 , Fig.18 The third structural schematic diagram of the display device and the camera in the embodiment of the present application. In the embodiment of the present application, a mounting hole 272 can be opened on the lower substrate 270, and a mounting hole 2942 can be set on the first light-transmitting portion 294, and a mounting hole 2342 can be set on the second light-transmitting portion. The mounting hole 272 of the lower substrate 270, the mounting hole 2942 of the first light-transmitting portion 294, and the mounting hole 2342 of the second light-transmitting portion 2942 can be interconnected. In the embodiment of the present application, part or all of the functional devices such as the camera 60 and / or the sensor can be installed in the mounting hole 2942, the mounting hole 2342, and the mounting hole 272.

[0123] It can be understood that the mounting hole 2942 of the first light-transmitting portion 294 can also be referred to as a first mounting hole 2942, and its size can be set according to the requirements of functional devices such as the camera 60, for example, the first mounting hole 2942 is slightly smaller than the first light-transmitting portion 294. The mounting hole 2342 of the second light-transmitting portion can also be referred to as a second mounting hole, and its size can be set according to the requirements of functional devices such as the camera 60, for example, the second mounting hole 2342 is slightly smaller than the second light-transmitting portion 234. The mounting hole 272 of the lower substrate 270 can be defined as a third mounting hole.

[0124] It should be noted that when installing functional devices such as the camera 60, the camera 60 is generally composed of a lens and a base, and the volume of the lens is usually smaller than the base of the base, such as the cross section of the lens is smaller than the cross section of the base. Therefore, the space required to store the camera 60 lens is smaller than the space to store the camera base. Therefore, the embodiment of the present application can set the area of ​​the first mounting hole 2942 parallel to the display surface of the display device 20 to be larger than the area of ​​the second mounting hole 2342 parallel to the display surface of the display device 20, and set the area of ​​the third mounting hole 272 parallel to the display surface of the display device 20 to be larger than the first mounting hole 2942. It can be understood that the embodiment of the present application can also set the area of ​​the second mounting hole 2342 parallel to the display surface of the display device 20 to be larger than the area of ​​the first display portion 214 parallel to the display surface of the display device 20. In other words, the projection of the third mounting hole 272 on the display layer 210 covers the first mounting hole 2942, and the projection of the first mounting hole 2942 on the display layer 210 covers the projection of the second mounting hole 2342 on the display layer 210.

[0125] It should be noted that the projection of the second mounting hole 2342 on the display layer 210 covers the first display area 240 , and the first display area 240 is spatially located within the second mounting hole 2342 , so that functional devices such as the camera 60 can transmit signals.

[0126] For example, the first mounting hole 2942 , the second mounting hole 2342 and the third mounting hole 272 are all circular holes, the diameter of the third mounting hole 272 may be greater than the diameter of the first mounting hole 2942 , and the diameter of the first mounting hole 2942 may be greater than the diameter of the second mounting hole 2342 .

[0127] It is understandable that, in the embodiment of the present application, the first mounting hole 2942, the second mounting hole 2342 and the third mounting hole 272 may be set to be substantially equal. For example, the diameters of the first mounting hole 2942, the second mounting hole 2342 and the third mounting hole 272 may be the same. In the embodiment of the present application, the area of ​​the second mounting hole 2342 parallel to the display surface of the display device 20 may be set to be equal to the area of ​​the first display portion 214 parallel to the display surface of the display device 20.

[0128] See also Fig.19 , Fig.19 2 is a fourth structural diagram of the display device and the camera in the embodiment of the present application. In the embodiment of the present application, a third mounting hole 272 can be opened on the lower substrate 270, and a first mounting hole 2942 can be opened on the first light-transmitting portion 294. The first mounting hole 2942 is connected to the third mounting hole 272. The first mounting hole 2942 can refer to Fig.18 The first mounting hole 2942 shown. It should be noted that when the first mounting hole 2942 is a blind hole, the opening of the first mounting hole 2942 is away from the second driving layer 230 to ensure that the first mounting hole 2942 and the third mounting hole 272 are connected to each other. In the embodiment of the present application, part or all of the functional devices such as the camera 60 and / or the sensor can be installed in the first light-transmitting hole 2942 and the third mounting hole 272.

[0129] However, in the embodiment of the present application, it is also possible to open only the third mounting hole on the lower substrate 270. Fig. 20 , Fig. 20 The third mounting hole 272 provided in the lower substrate 270 can be arranged corresponding to the first light-transmitting portion 294 and the second light-transmitting portion 234, and part or all of the camera 60 and / or functional devices such as sensors can be installed in the third mounting hole 272.
