The display device 20 may have 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 have an irregular shape, which is not limited in the embodiments of the present application.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a display device in the electronic apparatus shown in fig. 1. The display device 20 may include a first display area 240 and a second display area 220, both the first display area 240 and the second display area 220 may display a screen, and the first display area 240 and the second display area 220 may display the same screen or different screens.

The first display area 240 and the second display area 220 may be adjacent to each other, such as 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, i.e., the first display area 240 is located at an end surface position or an end surface connection position of the display device 20. It is understood that the end surface connection position of the display device 20 is a position where both end surfaces of the display device 20 are connected to each other, and may include a portion of both end surfaces connected to each other. It should be noted that there may be one or a plurality of first display regions 240, and when there are a plurality of first display regions 240, the plurality of first display regions 240 may be located on the same end surface of the display device 20, may be located on a plurality of end surfaces of the display device 20, or may be located at a plurality of end surface connection positions of the display device 20. Or a part of the plurality of first display regions 240 is located at the end surface connection position of the display device 20 and a part is located at the end surface position of the display device 20.

Such as the light transmittance of the first display region 240 may be set to be greater than the light transmittance of the second display region 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 functional devices of the electronic device 100, such as the camera 60 and sensors, can be arranged at the position of the first display area 240, so as to improve the quality of signal transmission realized by the camera 60 and sensors through the first display area 240.

The light guide column can transmit light signals emitted by functional devices such as the camera 60 and the sensor to the first display area 240, and transmit the light transmitted from the first display area 240 to the outside of the electronic device 10. The light guide column can also transmit an external light signal of the light-transmitting first display area 240 to the camera 60, the sensor and other functional devices. The light guide column can be of a cylindrical structure or a multi-section structure. When the light guide column is in a multi-section structure, the light guide column can be provided with at least one light guide surface to reflect light signals.

In order to set the light transmittance of the first display region 240 to be greater than the light transmittance of the second display region 220, the embodiment of the present application may set a driving unit such as a Thin Film Transistor (TFT) that drives the first display region 240 in the display device 20 outside the first display region 240. For example, in the driving layer structure for driving the second display area 220 in the display device 20, for example, 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 dual-layer driving layer structure is disposed in the display device 20, and a driving unit such as a TFT for driving the first display region 240 is disposed in the driving layer structure corresponding to the second display region 220 by using a via hole.

Referring to FIG. 3, FIG. 3 is a cross-sectional view of the display device shown in FIG. 2 taken along the direction P2-P2. The display device 20 may include an upper substrate 250, a display layer 210, a driving layer 230, and a lower substrate 270, which are sequentially stacked. The display device 20 may drive the display layer 210 through the driving layer 230 to display a screen. Here, the upper substrate 250 and the lower substrate 270 may be made of a transparent material, such as transparent glass. The lower substrate 270 may be defined as a first substrate, and the upper substrate 250 may serve as a second substrate.

Referring to fig. 4, fig. 4 is a partial schematic view of the display device shown in fig. 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 second display portion 214 located in the first display area 240

A plurality of first pixels of the first display area 240. The plurality of second pixels and the plurality of first pixels may be arranged in an array. The arrangement of the first pixels 242 of the first display area 240 may be one of a standard RGB arrangement, a Pentile arrangement, or a Delta arrangement, and the arrangement of the second pixels 222 of the second display area 220 may be one of a standard RGB arrangement, a Pentile arrangement, or a Delta arrangement. It should be noted that the first pixels 242 in the first display area 240 may also adopt other arrangement manners, and the second pixels 222 in the second display area 220 may also adopt other arrangement manners.

It is to 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,

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

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

Wherein the driving layer 230 may include a plurality of driving units, each of which may drive at least one pixel. Wherein the driving layer 230 includes 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 one first pixel and may drive one first pixel. Each second driving unit is electrically connected with one second pixel and can drive one second pixel. The driving layer 230 may include a second driving part 232 positioned at the second display area 220 and a first driving part 234 positioned at the first display area 240, a plurality of second driving units may be disposed in the second driving part 232, and a plurality of first driving units may be disposed in the first driving part 234.

Among them, the driving unit may adopt one of driving circuits such as 2T1C, 5T1C, 7T1C, etc. For example, the first driving unit may adopt one of 2T1C, 5T1C, 7T1C, and the second driving unit adopts one of 2T1C, 5T1C, 7T 1C. Where T denotes a thin film transistor, and C denotes a capacitance. In order to improve the light transmittance of the first display region 240, the first driving unit disposed in the first display region 240 may be a simpler driving circuit than the main driving unit of the second display region 220, for example, the first driving unit may include a smaller number of thin film transistors than the second driving unit. For example, the first drive unit may employ one of 2T1C, 5T1C, and the second drive unit may employ 7T 1C. The number of the opaque tfts in the first driving unit is less, and the number of the opaque portions in the first display area 240 is less, so that the light transmittance of the first display area 240 can be improved.

The physical structures of the second pixels 242 of the second display region 220 and the first pixels 222 of the first display region 240 may be the same, or the second display region 220 and the first display region 240 may have the same pixel physical structure. Such as the size of the second pixels 222 being the same as the size of the first pixels 242 and the arrangement of the second pixels 222 being the same as the arrangement of the first pixels 242. Can be formed in the same process. It should be noted that the physical structures of the second pixels 222 of the second display area 220 and the first pixels 242 of the first display area 240 may also be different. Such as the size of the second pixels is larger than that of the first pixels, and the arrangement density of the second pixels is larger than that of the first pixels. It should be noted that fig. 4 only shows a part of the pixels of the display device 20, and the area formed by the arrangement of the first pixels 242 shown in fig. 4 is substantially the same as the area formed by the arrangement of the second pixels 222.

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

Referring to fig. 5, fig. 5 is another partial schematic view of the display device shown in fig. 2. Fig. 5 illustrates the plurality of second driving units 224 of the second display area 220 and the plurality of first driving units 246 of the first display area 240. One of the second driving units 224 may be electrically connected to one of the second pixels 222, and one of the second driving units 224 may drive one of the second pixels 222. Each of the first pixel sets 244 may be electrically connected to a first driving unit 246, and a first driving unit 246 may drive one of the first pixel sets 244, i.e., one first driving unit 246 may drive all the first pixels 242 in one of the first pixel sets 244. Compared with the case that one driving unit drives one pixel, the number of the first driving units can be reduced. The embodiment of the present application may dispose the first driving unit 246 at the first display area 240, such as at the first driving part 234. Since the driving of the plurality of 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 fig. 5 only shows a part of the second driving unit 224 and a part of the first driving unit 246 of the display device 20, and the area formed by the arrangement of the first driving unit 246 shown in fig. 5 is substantially the same as the area formed by the arrangement of the second driving unit 224.

The embodiment of the present application can use a first pixel set 244 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 same-color first pixels 242 or sixteen same-color first pixels 242. For another example, the first pixel set 244 as a first display unit includes a plurality of first pixels 242 with different colors. The plurality of second pixels 222 of the second display area 220 may form a second display unit, or a second pixel unit, such as the second pixel unit of the second display area 220 including 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 one white pixel or one yellow pixel.

The embodiment of the present application can also use a plurality of first pixel sets 244 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. The one first pixel set 244 as in the first display unit may include four same-color first pixels 242 or sixteen same-color first pixels 242. For example, a first display unit includes three first pixel sets 244, one first pixel set 244 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.

Referring to fig. 6, fig. 6 is a first layout diagram of a first display unit in a first display area of the display device shown in fig. 2. One first display unit 216a of the first display region 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 244 c. The first set of pixels 244a may include four red pixels 242(R), the first set of pixels 244B may include four green pixels 242(G), and the first set of pixels 244c may include four blue pixels 242 (B). It should be noted that the arrangement of the plurality of first pixel sets in one first display unit is not limited to this.

Referring to fig. 7, fig. 7 is a second arrangement diagram of a first display unit in a first display area of the display device shown in fig. 2. One first display unit 216b of the first display region 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 244 f. First set of pixels 244d can include four red pixels 242, first set of pixels 244e can include four green pixels 242, and first set of pixels 244f can include four blue pixels 242.

Referring to fig. 8, fig. 8 is a third schematic layout diagram of a first display unit in a first display area of the display device shown in fig. 2. One first display unit 216c of the first display region 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 244 j. First set of pixels 244h can include four red pixels 242, first set of pixels 244i can include four green pixels 242, and first set of pixels 244j can include four blue pixels 242.

Referring to fig. 9, fig. 9 is a fourth arrangement diagram of a first display unit in a first display area of the display device shown in fig. 2. One first display unit 216d of the first display region 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 244 n. First set of pixels 244k can include four red pixels 242, first set of pixels 244m can include four green pixels 242, and first set of pixels 244n can include four blue pixels 242.

It is to be understood that when one first display unit of the first display region 240 includes four first pixel sets 244, each first pixel set 244 of the four first pixel sets 244 includes first pixels 242 of the same color, such as one first pixel set 244 including a plurality of red pixels, a second first pixel set 244 including a plurality of green pixels, a third first pixel set 244 including a plurality of blue pixels, a fourth first pixel set 244 including a plurality of white pixels, or a fourth first pixel set 244 including a plurality of yellow pixels.

Fig. 6 to 9 only show several arrangements of one first display unit in the first display area 240 of the display device 20, and other arrangements of one first display unit in the first display area 240 of the embodiment of the present application are also possible.

It should be noted that, in some aspects, in order to improve the light transmittance of the first display region, the size of the first pixels in the first display region may be set to be larger than the second pixels in the second display region, and the arrangement of the first pixels in the first display region may be further sparse than the arrangement of the second pixels in the second display region. Thus, the first pixels of the first display area and the second pixels of the second display area have different pixel physical structures. In an actual process, since the first pixels in the first display region and the second pixels in the second display region have different physical pixel structures, different masks (or called masks) are used to form the pixel structures through a series of processes such as exposure, development, cleaning, and the like. For example, a first pixel of a first display area is formed by a first set of processes using a first type of mask, and a second pixel of a second display area is formed by a second set of processes using a second type of mask. Not only needs extra light shield and tool, but also increases the process, increases the processing cost and complexity, and reduces the yield of the formed pixels.

In order to save tools and process procedures, the first pixels of the first display area and the second pixels of the second display area may be formed under the condition of the same process, the same photomask and the like, so that the physical structures of the first pixels of the first display area and the second pixels of the second display area are the same. However, if the physical structures of the first pixels of the first display area and the second pixels of the second display area are the same, and the driving manners of the first pixels of the first display area and the second pixels of the second display area are the same, the first display area may be disposed with too many wires and the first driving unit, and the light transmittance of the first display area may be affected by the too many wires.

Based on the related scheme, in order to solve the problems of the process and the process cost and reduce the arrangement of the signal lines in the first display area, so as to facilitate the arrangement of the lines in the first display area and improve the light transmittance of the first display area, in the embodiment of the present application, at least two pixels in the first display area are connected in parallel to form a first pixel group. A plurality of first pixels can be connected to same signal line after the parallel connection, compare each first pixel and all connect a signal line and can save the number of signal line greatly, the signal line of being convenient for arrange, can also improve the luminousness of first display area simultaneously.

Therefore, in the embodiment of the application, at least two first pixels in the first display area are connected in parallel to form one first pixel group, so that on the premise of not changing the physical structure of the pixels of the whole display device, the number of signal lines arranged at the position of the first display area can be greatly reduced by changing the wiring at the position of the display layer of the first display area, and further, the light transmittance of the first display area is improved.

In order to further improve the light transmittance of the first display region 240, a portion of all the first driving units for driving the first display region 240 may be disposed in the first display region 240, and another portion may be disposed in other positions, such as the second display region 220, such as a portion of the first driving units disposed in the first driving part 234 and another portion disposed in the second driving part 232.

Of course, the embodiment of the present application may also dispose all the first driving units for driving the first display area 240 at other positions, such as disposing all the first driving units in the second display area 220.

It should be noted that if the first driving unit 246 for driving the first pixel 242 in the first display area 240 is disposed in the second display area 220, such as the second driving portion 232, the wiring needs to be arranged. Considering that the wiring occupies a space at a connection position of the first display area 240 and the second display area 220, if there are too many lines and the space may not be sufficiently arranged, it is necessary to increase the thickness to arrange more lines. In order to ensure that the connection positions of the first display area 240 and the second display area 220 can be wired in a sufficient space without increasing the thickness of the wiring positions, 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, the number of signal lines can be greatly reduced, the occupation of the space by the signal lines can be reduced, and the first driving unit 246 for driving the first pixels 242 in the first display area 240 can be arranged in the second display area 220.

However, it is considered that the second display area 220 is a main display portion of the display device 20. If the first driving units 246 for driving the first display area 240 are all disposed in the second display area 220, the disposition of the second driving portions 232 disposed in the second display area 240 and the wiring process of the second driving portions 232 may be affected, which may affect the quality and effect of the display image of the second display area 220. To this end, in the embodiment of the present application, in order to reduce the influence of the first driving unit 246 on the second display area 220, a third display area may be disposed between the second display area 220 and the first display area 240, and a transition may be formed to dispose the first driving unit in the third display area to reduce the influence of the first driving unit 246 on the second display area 220.

Referring to fig. 10, fig. 10 is another schematic structural diagram of a display device according to an embodiment of the present disclosure. 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 connect 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 from the first display area 240 without being directly connected. In the embodiment of the present application, the third display area 260 may also connect the second display area 220 and a portion of the first display area 240, and the second display area 220 and another portion of the first display area 240 may also be directly connected. The size of the third display region 260 may be much smaller than the size of the second display region 220, and the first display region 240 and the third display region 260 may together form an auxiliary display region of the display device 20, where the first display region 240 and the third display region 260 may be defined as an auxiliary display region, or an auxiliary display region.

Referring to fig. 11, fig. 11 is a cross-sectional view of the display device shown in fig. 10 taken along the direction P6-P6. The display layer 210 may also include a third display portion 216 located in a third display area 260. The third display portion 216 may have a plurality of third pixels arranged, and the arrangement of the third pixels may be one of a standard RGB arrangement, a Pentile arrangement, and a Delta arrangement, but the third pixels may have another arrangement. The driving layer 230 may further include a third driving portion 236, and the third driving portion 236 may include a plurality of driving units, such as the third driving portion 236 includes a plurality of third driving units, one third driving unit may be electrically connected to one third pixel, and one third driving unit may drive one third pixel. The third driving unit may employ one of 2T1C, 5T1C, 7T 1C. For example, the third driving unit employs 5T1C, the third display area 260 may employ 5T1C, the first display area 240 may employ 2T1C, and the second display area 220 may employ 7T1C in the embodiment of the present application. Therefore, the quality of the display image of the second display area 220 can be higher than that of the display image of the third display area 260, and the quality of the display image of the third display area 260 is higher than that of the display image of the first display area 240, so that transition can be presented between the first display area 240 and the second display area 220.

Of course, the driving manner of the first display area 240, the second display area 220, and the third display area 260 is not limited thereto. For example, the first display area 240 and the third display area 260 each employ 5T1C, and the second display area 220 employs 7T 1C.

Referring to fig. 12, fig. 12 is a first partial schematic view of the display device shown in fig. 10. The arrangement of the third pixels 262 of the third display region 260 may be the same as the arrangement of the second pixels 224 of the second display region 220, and may also be the same as the arrangement of the first pixels 242 of the first display region 240. For example, the second display region 220, the third display region 260 and the first display region 240 have the same physical structure of pixels, and the pixels of the second display region 220, the third display region 260 and the first display region 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. Fig. 11 only shows a part of the pixels of the display device 20, and the size of 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 shown in fig. 11 are substantially the same.

The embodiment of the present application may dispose all the first driving units for driving the first display area 240 in the third display area 260, such as disposing the first driving units in the third display part 236. The driving layer structure of the first display area 240 may be made without a first driving unit, such as the first driving portion 234 of the first display area 240 without a thin film transistor, and the light transmittance of the first display area 240 may be greatly improved. Meanwhile, other problems caused by the arrangement of the first driving unit in the first display area 240, such as diffraction problem caused by the imaging of the first driving unit arranged periodically to the camera 60 and stray light problem caused by the imaging of the first driving unit to the camera 60 by reflection and refraction, can be avoided.

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 occupy the space of the third driving portion 236. The application of the first driving unit disposed in the third driving portion 236 may also occupy the space of the third driving portion 236, and the wiring may also occupy the space of the third driving portion 236. To ensure that the first driving unit can be disposed in the third driving portion 236, the wiring of the third driving portion 236 can be made thinner to reduce the occupation of space by a single signal line to accommodate the arrangement of more signal lines.

Of course, in the embodiment of the present application, the first driving unit may be disposed in the third driving portion 236 without changing the thickness of the wiring in the third driving portion 236, and the wiring may be satisfied. The number of the third driving units of the third display region 260 is reduced.

With continued reference to fig. 12, a plurality of third pixel sets 264 may be disposed in the third display area 260, and 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 set of pixels 264 may also include at least two third pixels 262 of different colors, such as red and green pixels. The plurality of third pixels 262 in one third pixel set 264 may be connected together by a plurality of signal lines. The number of the third pixels 262 in one third pixel set 264 may be greater than the number of the first pixels 242 in one first pixel set 244, for example, one third pixel set 264 includes four third pixels 262, and one first pixel set 244 includes sixteen first pixels 242. Of course, the same number of third pixels 262 in a third set of pixels 264 as the number of first pixels 242 in a first set of pixels 244 is also possible.

The embodiment of the present application may use a third pixel set 264 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 and 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 with different colors.

The embodiment of the present application may further use a plurality of third pixel sets 264 as a third display unit, for example, three third pixel sets 264 may be used as a third display unit, and for example, four third pixel sets 264 may be used as a third display unit. The third pixel set 264 as one of the third display units may 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 third pixel set 264 of the three third pixel sets 264 includes four red pixels, another third pixel set 264 includes four green pixels, and the third pixel set 264 includes four blue pixels. The number of the third display units including the third pixel sets 264 and the arrangement of the third pixels 262 in the third display units can refer to the structure of the first display unit shown in fig. 6 to 9, and are not repeated herein.

It is to be understood that when one third display unit of the third display region 260 includes four third pixel sets 264, each third pixel set 264 of the four third pixel sets 264 includes the same color of the third pixel 262, such as one third pixel set 264 includes a plurality of red pixels, a second third pixel set 264 includes a plurality of green pixels, a third pixel set 264 includes a plurality of blue pixels, a fourth third pixel set 264 includes a plurality of white pixels, or a fourth third pixel set 264 includes a plurality of yellow pixels.

Referring to fig. 13, fig. 13 is a second partial schematic view of the display device shown in fig. 10. Fig. 13 illustrates the plurality of second driving units 224 of the second display area 220, the plurality of third driving units 266 of the third display area 260, and the plurality of first pixel units 246. The second driving unit 224 can refer to the content shown in fig. 5, and is not described herein again. Wherein 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 disposed within the third driving part 236.

The plurality of third driving units 266 are used for driving the third display area 260, each of the third driving units 266 may be electrically connected to one of the third pixel sets 264, and one of the third driving units 266 may drive one of the third pixel sets 264, that is, one of the third driving units 266 may drive all of the third pixels 262 in one of the third pixel sets 264. Compared with one driving unit driving one pixel, the embodiment of the present application can reduce the number of the third driving units, thereby reducing the occupation of the third driving unit on the space of the third driving portion 236, and the first driving unit 246 can be provided. Such as a third pixel set 264 comprising four parallel connected third pixels 262, a third driving unit 266 may occupy the space corresponding to one third pixel 262, or slightly smaller than the space corresponding to the third pixel 262. Accordingly, one third pixel set 264 may leave a space corresponding to at least three third pixels 262, and a plurality of first pixel units 264, such as three first driving units 246, may be disposed in the vacant space. The three third pixels 262 that are left vacant may be disposed in one-to-one correspondence with the three first driving units 246.

Therefore, in the embodiment of the present application, at least two third pixels 262 in the third display area 260 may be connected in parallel to form a third pixel set 264, the driving of the plurality of third pixels 262 may be implemented by one third driving unit 266, and the first driving unit 246 may be disposed in the third driving portion 236 with a sufficient space. Therefore, the opaque thin film transistor in the first display area 240 can be set to the third display area 260 which does not need to transmit light such as a camera to collect signals, the size of the third display area 260 can be set to be small, and the third display area 240 is connected with the second display area 220, and under the condition that the display picture of the second display area 220 is not greatly influenced, the quality of the display picture of the third display area 260 is poor and the display effect of the whole display device 20 is not greatly influenced.

In addition, the number of the third pixels 262 connected in parallel to each other in the third display region 260 may be smaller than the number of the first pixels 242 connected in parallel to each other in the first display region 240, and the display transition between the first display region 240 and the second display region 220 may be made smoother.

It should be noted that the position where the first driving unit is disposed in the embodiment of the present application is not limited to the third display area 260. For example, a part of the first driving units is disposed in the third display area 260, another part of the first driving units is disposed in the first display area 240, another part of the first driving units is disposed in the third display area 260, another part of the first driving units is disposed in the second display area 220, and the first driving units are divided into three parts and disposed in the first display area 240, the third display area 260, and the second display area 220, respectively.

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

Referring to fig. 14, fig. 14 is a third partial schematic view of the display device shown in fig. 10. The display device 20 may further include a non-display region 280, and the first driving unit 246 driving the first display region 240 may be disposed in the non-display region 280. The display device 20 may be a full-screen, that is, the front surface of the display device 20 is substantially a display area, and the front surface of the display device 20 is substantially equal to the display surface of the electronic apparatus when viewed from the front surface of the electronic apparatus. However, even if the display device 20 is a full-screen display device, the edge of the display device 20 still has the non-display area 280, and the non-display area 280 can be understood as a black edge of the display device 20, and the width of the black edge can be very narrow, for example, the width of the black edge is less than 1 mm or 0.5 mm. Because the area of the first display area 240 is small, the number of first pixels in the first display area 240 is relatively small, and a plurality of first pixels of 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, the first driving units 246 can be set to a black edge position, the light transmittance of the first display area 240 can be improved, and the second display area 220 or the third display area 260 cannot be affected. A plurality of first driving units 246 need to be disposed corresponding to the first pixels of the first display area 240, and the first driving units 246 may be all disposed at black edge positions.

In order to better accommodate all of the first driver units 246 at the black edge position, simpler first driver units 246 may be used, for example, the first driver units 246 may employ 2T1C, 5T1C, etc. driver circuits, and the number of thin film transistors in each first driver unit 246 may be smaller, and the space required for a single first driver unit 246 may be smaller. The first pixel distribution density in the first display area 240 may also be set lower, and the total number of the first driving units 246 used to drive the first display area 240 is smaller. It should be noted that the plurality of first driving units 246 may also be partially disposed in the non-display area 280 and partially disposed in other positions, such as the first display area 240 or the third display area 260.

It should be noted that, in the embodiment of the present application, a manner of increasing the light transmittance of the first display area 240 is not limited to this, and other manners may also be adopted. For example, the wiring of the display device 20 in the first display region 240 may be provided in a transparent structure to increase the light transmittance of the first display region 240. It is also possible, for example, to leave no polarizing structure at the location of the first display area 240. For example, the driving unit for driving the first display area 240 may be driven passively, so that the number of wirings and components in the driving unit may be reduced greatly. It is understood that a scheme of increasing the first display region 240 by increasing the light transmittance of the material and changing the arrangement of the wires is within the scope of the present application.

The second display area 220 in the embodiment of the present application may be an active matrix driving (AMOLED) display area, and the first display area 240 may be an active matrix driving (AMOLED) display area or a passive matrix driving (PMOLED) display area. In the embodiment of the present application, the first display area 240 may be 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 by the first display area 240 is lower than that of the second display area 220. Therefore, the embodiment of the present application may ensure that the main display area of the display device 20 has a high display effect by using the AMOLED for the second display area 220. Meanwhile, the first display area 240 adopts the PMOLED, the passively driven first display area 240 only needs one thin film transistor for driving, the number of the opaque thin film transistors is small, and the light transmittance of the first display area 240 can be greatly improved. Moreover, the area displayed by the first display area 240 may be much smaller than the area displayed by the second display area 220, for example, if the quality of the image displayed by the first display area 240 is reduced, the entire display of the display device 20 will not be greatly affected. 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 is close to that of the second display area 220.

In the embodiment of the present application, the third display area 260 can select an active driving display area or a passive driving display area as required. Since the physical structures of the third pixels 262 of the third display region 260 and the first pixels 242 of the first display region 240 are the same, the third display region 260 and the first display region 240 may be the same driving manner, such as the third display region 260 and the first display region 240 may be passive driving display regions. If the area of the third display area 260 is larger, or in order to improve the display quality of the third display area 260, the same driving display area may be used for the third display area 260 and the second display area 220, such as both active driving display areas.

Among them, the size and shape of the first pixel 242 in the first display region 240 may be set as desired. For example, the first pixel 242 may be rectangular or may be circular-like. The first pixel 242 having a circular-like shape may have a circular shape, an elliptical shape, a rounded rectangle, or the like. The circular-like first pixels 242 can improve the diffraction problem of the first display area 240 because the edge is an arc transition.

The embodiment of the present application may dispose the functional devices of the electronic apparatus 10, such as the camera 60, the sensor, etc., 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 disposed 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 acquire the external light signal transmitted 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 may be disposed at an interval, and of course, the lens of the camera 60 may 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 be an arc structure.

To reduce the space of the electronic device 10 occupied by the camera 60, the lens of the camera 60 may be close to or abut the lower substrate 270 of the display device 20. The lower substrate 270 of the display device 20 is mainly used for carrying other layer structures of the display device 20, and does not need a special function per se.

Referring to fig. 15, fig. 15 is a schematic view of a first structure of an electronic device according to an embodiment of the present disclosure, in which a display device and a camera are combined. 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 may be disposed on the lower substrate 270 opposite to the camera 60, and the camera 60 may be at least partially disposed in the first mounting hole 272. The first mounting hole 272 may be a blind hole, that is, the thickness of the portion of the lower substrate 270 relative to the camera 60 is smaller than that of the other portions, and the lower substrate 270 is also a complete substrate, which does not affect the function of bearing other layer structures of the display device 20 and can also leave a space to accommodate the camera 60. The mounting manner of the first mounting hole 272 and the camera 60 may be set according to the size of the first mounting hole 272 and the size of the camera 60. Illustratively, if the space of the first mounting hole 272 is insufficient to mount the entire camera head 60, the lens portion of the camera head 60 may be disposed within the first mounting hole 272. If the camera head is small enough, the entire camera head 60 may be disposed within the first mounting hole 272.

It should be noted that the camera may be replaced by other functional components of the electronic device 10, such as a sensor, that is, at least a portion of the sensor of the electronic device 10 may be disposed in the first mounting hole 272.

Referring to fig. 16, fig. 16 is a schematic view of a second structure of the electronic device according to the embodiment of the present disclosure, in which the display device and the camera are combined. Since the driving layer 230 of the first display area 240 may not be provided with the first driving unit, the camera 60 may be mounted into the driving layer. Specifically, the first mounting hole 272 formed in the lower substrate 270 is a through hole, the driving layer of the first display area 240 has a second mounting hole 238 opposite to the camera 60, the first mounting hole 272 and the second mounting hole 238 are communicated, and the camera 60 may be at least partially located in the second mounting hole 238. For example, the lens of the camera head 60 is positioned within 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 formed after a portion of the stacked 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 disposed on the lower substrate 270, the first mounting hole 272 and the second mounting hole 238 are formed by a laser or the like corresponding to the lens position of the camera 60.

It should be noted that the camera may be replaced with other functional components of the electronic device 10, such as a sensor, that is, at least a portion of the sensor of the electronic device 10 may be disposed in the first mounting hole 272 and the second mounting hole 238.

It can be understood that the camera 60 corresponding to the first display area 240 may be a front camera of the electronic device, the front camera is generally a camera whose lens cannot move, the lower substrate and the driving layer of the display device 20 may be provided with a first mounting hole and a second mounting hole, and then the camera 60 corresponding to the first display area 240 may be a camera whose lens can move, and the lens of the camera 60 can move to implement functions such as auto focus. It should be noted that the camera 60 may also be a rear camera, that is, the electronic device 10 may be provided with two opposite display devices 20.

One camera 60 may be disposed below the first display area 240, or a plurality of cameras 60 may be disposed. The plurality of cameras 60 can be the cameras 60 that cooperate with each other, such as two the same cameras, a common camera and a blurring camera or black and white camera, and other functional devices, such as proximity sensor, light sensor, distance measuring sensor, fingerprint identification sensor, etc., can also be set up in addition to setting up the camera below the first display area 240.

The light transmittance of the first display area 240 can be improved by using a multi-layer driving layer, such as two driving layers of the display device, and the first driving unit for driving the first display area is disposed on one of the driving layers and is far away from the first display area. And arranging a second driving unit for driving the second display area on the other layer of driving layer and far away from the first display area. Therefore, the driving unit corresponding to the first display area can be arranged at a position far away from the first display area, and the light transmittance of the first display area can be greatly improved. The scheme for improving the light transmittance of the first display region by two driving layers is described in detail below with reference to the accompanying drawings.

Referring to FIG. 17, FIG. 17 is a cross-sectional view of the display device shown in FIG. 2 taken along the direction P4-P4. The display device 20 may include an upper substrate 250, a display layer 210, a second driving layer 230, a first driving layer 290, and a lower substrate 270, which are sequentially stacked. The display device 20 may drive the display layer 210 through the first driving layer 290 and the second driving layer 230 to realize display of a screen. The display layer 210 shown in fig. 17 may refer to the display layer 210 shown in fig. 3, the upper substrate 250 shown in fig. 17 may refer to the upper substrate 250 shown in fig. 3, and the lower substrate 270 shown in fig. 17 may refer to the lower substrate 270 shown in fig. 3, which is not described herein again.

Wherein the second driving layer 230 shown in fig. 17 may include a second light-transmitting portion 234 and a second driving portion 232. Wherein the second driving part 232 may be provided with a plurality of second driving units, and the second driving units provided in the second driving part 232 may drive the second pixels in the second display region 220. The second driving part 232 may be disposed in the second display region 220, or the second driving part 232 may be disposed corresponding to the second display part 212, such as the second driving part 232 is disposed to be stacked with the second display part 212. 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 a driving unit, but also be provided with a circuit.

Wherein at least a portion of the second light-transmitting portion 234 may be disposed in the first display region 240. Such as the second light transmitting portion 234 is disposed in the first display region 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 is stacked with the first display portion 214. The second light-transmitting portion 234 may not be provided with a driving unit to increase the light transmittance of the second light-transmitting portion 234, and thus, the light transmittance of the first display region 240 may be increased. 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 the first display portion 214 in a direction perpendicular to the display device 20, or a projection of the second light-transmitting portion 234 on the display layer 210 overlaps a projection of the first display portion 214 on the display layer 210. Of course, it is also possible that the size of the first display portion 214 is slightly smaller than the size of the second light-transmissive 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-transmissive 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, so that a portion of the second driving layer 230 corresponding to the first display portion 214 is ensured to have no driving unit, and the light transmittance of the first display area 240 can be ensured to be improved.

Note that a part of second light transmitting portion 234 may be provided to correspond to second display portion 212, and a part of second driving layer 230 provided to correspond to first display portion 214 may be provided without a driving unit.

Referring to fig. 17, the second driving layer 230 is provided with a plurality of vias 2322, and the plurality of vias 2322 penetrate through the second driving layer 230 in the thickness direction of the second driving layer 230. One or more signal lines may be disposed within each via 2322. The via hole 2322 may be disposed at the second driving portion 232 without being disposed at the position of the second transparent portion 234, so that the second transparent portion 234 may be ensured to have no driving circuit, and the number of the bus lines of the second transparent portion 234 may be reduced or no wiring may be disposed at the position of the second transparent portion 234.

Wherein the first driving layer 290 shown in fig. 17 may include a first driving portion 292 and a first light-transmitting portion 294. Wherein the first driving part 292 may be provided with a plurality of first driving units, and the first driving unit provided in the first driving part 292 may drive the first pixel in the first display area 240. The first driving part 292 may be disposed in the second display area 220, or the first driving part 292 may be disposed corresponding to the second display part 212, such as three of the first driving part 292, the second driving part 232 and the second display part 212 stacked in sequence. The first driving portion 292 and the first light transmitting portion 294 define the position of the first driving layer 290, and the first driving portion 292 may be provided with not only a driving unit but also a wiring.

Wherein at least a portion of the first light-transmitting portion 294 may be disposed at the first display region 240. For example, the first transparent portion 294 is disposed in the first display area 240, or the first transparent portion 294 may be disposed corresponding to the first display portion 214, such as the first transparent portion 294, the second transparent 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 light transmittance of the first light-transmitting portion 294, and thus, the light transmittance of the first display region 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 the first display portion 214 in a direction perpendicular to the display layer 210, or a projection of the first light-transmitting portion 294 on the display layer 210 overlaps a projection of the first display portion 214 on the display layer 210. Of course, it is also possible that the size of the first display portion 214 is slightly smaller than the size of the first light-transmissive 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-transmissive 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, so that a portion of the first driving layer 290, which corresponds to the first display portion 214, is ensured to have no driving unit, and the light transmittance of the first display area 240 can be ensured to be improved.

Note that a part of the first light transmission portion 294 may be provided to correspond to the second display portion 212, and it is sufficient that no driving means is provided in a portion where the first driving layer 290 is provided to correspond to the first display portion 214.

In the embodiment of the present invention, the second transparent portion 234 is located between the first transparent portion 294 and the first display portion 214, and the first transparent portion 294, the second transparent portion 234, and the first display portion 214 may be provided in the same size and overlap each other. Of course, the dimensional relationship among the first transparent portion 294, the second transparent portion 234, and the first display portion 214 is not limited thereto, and the dimensions of the first transparent portion 294, the second transparent portion 234, and the first display portion 214 are sequentially reduced. For another example, the size of the first light transmission portion 294 is smaller than the size of the second light transmission portion 234 and the first display portion 214, and the size of the second light transmission portion 234 is the same as the size of the first display portion 214. For example, the size of the first light transmission portion 294 is the same as the size of the second light transmission portion 234, and the size of the first light transmission portion 294 and the second light transmission portion 234 is smaller than the size of the first display portion 214.

In the embodiment of the application, a signal line may penetrate into the via hole 2322, and the signal line may electrically connect the first pixel of the first display region 240 with the first driving unit of the first driving layer 290, for example, the signal line may 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 may drive the first pixel. For the first pixel, reference may be made to the first pixel 242, and the first driving unit may drive the first driving unit 246, which is not described herein again.

One end of the signal line may be electrically connected to the first pixel of the first display region 240, the signal line may be electrically connected to the first pixel and arranged to the second display region 220, the second display region 220 passes through the via 2322, and the other end of the signal line may be electrically connected to the first driving unit of the second display region 240. Such as one end of a signal line electrically connected to the first pixel of the first display portion 214, the signal line may be routed from the second transparent portion 234 to the second driving portion 232, penetrate through the via 2322 at the position of the second driving portion 232, and penetrate through the via 2322 to the first driving portion 292 to electrically connect to the first driving unit of the first driving portion 292. Thereby realizing that the first driving unit is not disposed in the first display region 214 and driving of the first pixels in the first display region 214 is realized. It should be noted that, in the actual wiring process, the arrangement of the first pixels may be more sparse than that of the second pixels, or the size of the first pixels is larger than that of the second pixels, or a plurality of first pixels are connected in parallel, so that the number of signal lines may be greatly reduced, and the signal lines may be arranged in the second light-transmitting portion 234 and pass through the via-hole 2322.

Therefore, in the display device 20 shown in fig. 17 of the present application, the driving units can be arranged at the positions of the second display areas 220 by arranging two driving layers, and the driving units are not arranged at the positions of the first display areas 240, so that the light transmittance of the first display areas 240 can be improved.

Here, the plurality of via-holes 2322 may be all disposed at the second driving part 232 and may be disposed around the second light-transmitting part 234, such as the plurality of via-holes 2322 are disposed around the second light-transmitting part 234 at equal intervals. In the embodiment of the present application, the plurality of via holes 2322 are disposed around the second transparent portion 234, and compared with the case that the plurality of via holes 2322 are disposed at a certain position in a concentrated manner, the via holes 2322 can be distributed and arranged, so that not only is the arrangement of lines easily achieved, but also the length of signal lines can be reduced. It should be noted that the internal space of the display device 20 is limited, and the arrangement of the plurality of vias at the same position may additionally occupy the space of the second driving layer 230, which affects the arrangement of the internal traces of the second driving layer 230. In the present application, the plurality of vias 2322 are arranged at intervals, so that the influence of the vias 2322 on the internal routing arrangement of the second driving layer 230 can be reduced, and the implementation is easier.

It can be understood that, if the via 2322 is disposed on the second driving portion 232, the second driving portion 232 is disposed with a plurality of second driving units, the plurality of second driving units occupy a space of the second driving portion 232, and a free space of the second driving portion 232 is limited. Therefore, the present embodiment may dispose the via-hole 2322 between the adjacent second driving units. Such as one, two, or three vias 2322 disposed between adjacent four second driving units. It is to be noted that the via 2322 may be provided between the thin film transistors of the second driving units.

In order to further improve the light transmittance of the first display region 240, the size of the first pixels in the first display region 240 may be set larger than the size of the second pixels in the second display region 220, such as four times, sixteen times, etc., the size of the first pixels. Therefore, the number of the first pixels in the first display portion 214 can be reduced, the number of the routing lines and the number of the first driving units of the first display portion 214 can be reduced, the first pixels of the first display portion 214 can be connected with the signal lines more easily, the signal lines pass through the via-holes 2322 to be connected with the first driving units, the number of the routing lines in the first display portion 214 can be reduced, and the light transmittance of the first display region 240 can be further improved.

It should be noted that the arrangement and size of the first pixels of the first display region 214 and the arrangement and size of the second pixels of the second display region 212 may be the same, that is, the first display region 214 and the second display region 212 may have the same physical pixel structure. If the first display area 214 and the second display area 212 may have the same pixel physical structure, the first pixel of the first display area 214 and the second pixel of the second display area 212 may specifically refer to fig. 4 to 9 and the corresponding contents thereof, and are not described herein again. For example, sixteen first pixels in the first display region 214 are connected in parallel to form a first pixel set, one first pixel set may be electrically connected to one first driving unit, sixteen first pixels in the first pixel set may have the same color, three first pixel sets may form one display unit of the first display region 214, a first pixel in the first pixel set may be a red pixel, a first pixel in the first pixel set may be a green pixel, and a first pixel in the first pixel set may be a blue pixel. Accordingly, the number of the first driving units, and thus the number of the vias 2322, may be reduced, and the number of wirings in the first display region 240, or in the first display portion 214, may also be reduced. Not only is it easier to connect the first pixel of the first display portion 214 with the signal line, which passes through the via 2322 to be connected with the first driving unit, but also the wiring within the first display portion 214 can be reduced, and the light transmittance of the first display region 240 can be further improved.

Therefore, in the embodiment of the present invention, when the display device 20 is combined with the camera 60 or the optical device such as the sensor, the transmission of the optical signal in the first display area 240 of the light-transmissive display device 20 by the device such as the camera 60 or the sensor is more easily realized.

It is understood that since neither the first light transmitting portion 294 nor the second light transmitting portion 234 is provided with a driving unit, functional devices of the electronic apparatus 10 may be provided at the first light transmitting portion 294 and the second light transmitting portion 234.

Referring to fig. 18, fig. 18 is a schematic view of a third structure of a display device and a camera according to an embodiment of the present disclosure.

The mounting hole 2342 of the second light-transmitting portion may also be referred to as a second mounting hole, and the size of the second mounting hole may be set according to the requirement of a functional device 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 may be defined as a third mounting hole.

It should be noted that when mounting the camera 60 and other functional devices, the camera 60 generally comprises a lens and a base, 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 for housing the lens of the camera 60 is smaller than the space for housing the camera base. Thus, the embodiment of the present application may 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 is understood that the embodiment of the present application may further 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 part 214 parallel to the display surface of the display device 20. Or 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.

It should be noted that the projection of the second installation hole 2342 on the display layer 210 covers the first display area 240, and the first display area 240 is spatially located in the second installation hole 2342 so as to facilitate the transmission of signals by a functional device such as the camera 60.

For example, the first, second, and third mounting

Such as the first mounting hole 2942, the second mounting hole 2342, and the third mounting hole 272, have the same diameter. The embodiment of the present application may further set an area of the second mounting hole 2342 parallel to the display surface of the display device 20 to be equal to an area of the first display portion 214 parallel to the display surface of the display device 20.

The first mounting hole 2942 communicates with the third mounting hole 272. The first mounting hole 2942 may be referenced to the first mounting hole 2942 shown in FIG. 18. It should be noted that, when the first mounting hole 2942 is a blind hole, the opening of the first mounting hole 2942 is far away from the second driving layer 230, so as to ensure that the first mounting hole 2942 and the third mounting hole 272 are communicated with each other. In the embodiment of the present application, a part or all of the functional devices such as the camera 60 and/or the sensor may be installed in the first light-transmitting hole 2942 and the third installation hole 272.
