A camera 60 is arranged in the electronic device 10, a lens of the camera 60 is arranged towards the second display area 240, and the camera 60 is used for acquiring an external light signal passing through the second display area 240 to form an image. It can also be understood that the camera 60 is disposed below the second display area 240 of the display device 20, and the camera 60 is configured to acquire an external light signal transmitted through the second display area 240 of the display device 20 and form an image according to the acquired external light signal.

The camera 60 may be a front camera of the electronic device, and the camera 60 may be configured to obtain images of a user, such as a self-photograph, through the second display area 240 of the display device 20.

In order to more fully understand the display device of the embodiments of the present application. The display device will be described in detail below.

Referring to fig. 2, fig. 2 is a first structural schematic diagram of a display device according to an embodiment of the present disclosure. The display device 20 in the embodiment of the present application may include a first display area 220 and a second display area 240 that are adjacent. The first display area 220 and the second display area 240 may be used to display text or images, and the first display area 220 and the second display area 240 may display the same image together, for example, the first display area 220 displays a part of a preset image, and the second display area 240 displays the rest of the preset image. The first display area 220 and the second display area 240 may also display different images, for example, the first display area 220 displays a preset image, and the second display area 240 displays a taskbar image. The first display area 220 and the second display area 240 can both display contents, the display area is complete, the screen occupation ratio of the display device 20 is high, the first display area 220 can surround the second display area 240, and the periphery of the second display area 240 can be adjacent to the first display area 220, that is, the second display area 240 is located in the middle of the first display area 220. The first display area 220 may also partially surround the second display area 240, and a part of the edge of the second display area 240 is adjacent to the first display area 220, for example, the second display area 240 is located at a corner of the display device 20 or located in the middle of the top end of the display device 20.

Wherein, the first display area 220 and the second display area 240 have different pixel physical structures. Referring to fig. 3 and 4, fig. 3 is a schematic view of a first partial structure of a display device according to an embodiment of the present disclosure, and fig. 4 is an enlarged view of a portion X of the display device in fig. 3. The first display area 220 includes a plurality of first pixels 226, the second display area 240 includes a plurality of second pixels 246, the size of the second pixels 246 is larger than that of the first pixels 226, the distance between the second pixels 246 and the size of the second pixels 246 are positively correlated, that is, the larger the size of the second pixels 246 is, the larger the distance between the second pixels 246 is, and therefore, the distribution density of the second pixels 246 in the second display area 240 is smaller than that of the first pixels 226 in the first display area 220.

The second display region 240 includes a plurality of pixel sets 242, each pixel set 242 includes at least two second pixels 246 connected in parallel, and the plurality of second pixels 246 connected in parallel in the second display region 240 may share one driving signal line, so as to reduce the number and total area of the driving signal lines. Considering that the driving signal lines can be non-light-transmitting metal wires, reducing the number of the driving signal lines can improve the light transmittance of the second display area 240, and improve the imaging effect of the camera. The driving signal lines can also be transparent ITO wiring, although the light transmittance of the ITO wiring is very high, partial ITO wiring is reduced, the light transmittance of the second display area 240 can be improved, the light transmittance of the second display area 240 can be larger than that of the first display area 220, and the camera can acquire external optical signal imaging penetrating through the second display area 240.

The first display area 220 and the second display area 240 have different pixel physical structures, and the corresponding driving units are arranged differently. Referring to fig. 5 and fig. 6 in combination with fig. 3 and fig. 4, fig. 5 is a schematic structural diagram of a driving circuit corresponding to a pixel of the display device in fig. 4, and fig. 6 is a schematic structural diagram of a pixel set and a first driving unit of the display device in fig. 4. The first display region 220 includes a plurality of first pixels 226 and a plurality of third driving units 228, and one third driving unit 228 drives one first pixel 226. For example, the first display region 220 includes M first pixels 226 and M third driving units 228.

The display device 20 further includes a plurality of first driving units 248, each first driving unit 248 is electrically connected to one of the pixel sets 242, and each first driving unit 248 is used for driving all the second pixels 246 of the one of the pixel sets 242 electrically connected thereto. The plurality of second pixels 246 of the second display area 240 share one first driving unit 248, and thus the total number of first driving units 248 for driving the second display area 240 can be reduced. For example, the second display region 240 includes N pixel sets 242, each pixel set 242 includes 4 second pixels 246, one pixel set 242 corresponds to one first driving unit 248, and the second display region 240 includes 4N second pixels 246 and N first driving units 248. The ratio of the first driving unit 248 and the second pixel 246 disposed in the second display area 240 is smaller than that of the first display area 220, the distribution density of the second pixel 246 is smaller than that of the first pixel 226, the distribution density of the first driving unit 248 in the second display area 240 is smaller than that of the third driving unit 228 in the first display area 220, and the first driving unit 248 and the third driving unit 228 both include opaque elements (such as thin film transistors TFT), i.e., the number of the opaque elements included in the second display area 240 is smaller than that of the first display area 220, so that the light transmittance of the second display area 240 can be larger than that of the first display area 220.

In order to further improve the light transmittance of the second display region, the first driving unit may be disposed in a region other than the second display region. Specifically, please refer to fig. 7, fig. 7 is a schematic diagram of a second partial structure of a display device according to an embodiment of the present disclosure. The display device further comprises a third display area 260. The third display area 260 connects the first display area 220 and the second display area 240, and it can also be understood that the third display area 260 is located between the first display area 220 and the second display area 240. Specifically, the second display area 240 is not directly connected to the first display area 220, but is connected through the third display area 260. The second display area 240 and the first display area 220 may also be partially directly connected and partially connected through the third display area 260. It should be noted that, different from the above-mentioned embodiment, in this embodiment, the second display area 240 is an area corresponding to a circular broken line in the figure, and the third display area 260 is an area between the second display area 240 and the first display area 220.

The plurality of second pixels of the second display region 240 and the plurality of third pixels of the third display region 260 may have the same physical structure, i.e., the same pixel size and the same pixel arrangement.

With reference to fig. 8 to 10, fig. 8 is a schematic structural diagram of a third portion of the display device according to the embodiment of the present application, fig. 9 is an enlarged schematic diagram of a portion Y of the display device in fig. 8, and fig. 10 is a schematic structural diagram of a third pixel and a driving unit in a third display area of the display device according to the embodiment of the present application. The plurality of first driving units 248 driving the second pixels 246 of the second display region 240 may be disposed in the third display region 260 in addition to the second display region 240. The camera does not need to acquire an external optical signal through the third display area 260, the plurality of first driving units 248 are arranged in the third display area 260, the first driving units 248 are not arranged in the second display area 240, the first driving units 248 which are not light-tight can not be arranged in the second display area 240, the light transmittance of the second display area 240 can be far greater than that of the first display area 220 and the third display area 260, and meanwhile, other problems caused by the first driving units 248 are reduced, for example, the diffraction problem caused by the first driving units 248 which are periodically arranged to image the camera, and the stray light problem caused by the reflection and refraction of the first driving units 248 to image the camera.

In addition, a plurality of first driving units 248 driving the second pixels 246 of the second display area 240 may also be disposed in the first display area 220. The first display region 220 has a large area, and a plurality of first driving units 248 may be disposed in the first display region 220.

It is understood that the plurality of first driving units 248 may also be disposed in two or three regions among the second display area 240, the third display area 260, and the first display area 220 as needed. Illustratively, the plurality of first driving units 248 are partially disposed in the second display area 240 and partially disposed in the third display area 260; or the plurality of first driving units 248 are partially disposed in the third display area 260 and partially disposed in the first display area 220; or the plurality of first driving units 248 are partially disposed in the second display area 240 and partially disposed in the first display area 220, or the plurality of first driving units 248 are partially disposed in the second display area 240, partially disposed in the third display area 260 and partially disposed in the first display area 220. For example, in order to facilitate the arrangement of the first driving unit 248, the connection of the first driving unit 248 with the second pixel 246 of the second display region 240 is simplified, a portion of the first driving unit 248 is disposed at the periphery of the second display region 240, and a portion of the first driving unit 248 is disposed in the third display region 260. For another example, in order to reduce the area of the third display region 260 and improve the overall display effect of the display device 20, a portion of the first driving unit 248 is disposed in the third display region 260, and a portion of the first driving unit 248 is disposed in the first display region 220.

The third display region 260 also includes a second driving unit that drives third pixels of the third display region 260. The third display area 260 further includes a plurality of second driving units 268, and one second driving unit 268 is electrically connected to one third pixel 266 of the third display area 260 and drives the third pixel 266 to emit light or not. When the third display area 260 is provided with the third pixels 266 and the second driving unit 268, the second driving unit 268 is disposed corresponding to the electrically connected third pixels 266, for example, the second driving unit 268 is disposed below the electrically connected third pixels 266 and at least partially opposite to the electrically connected third pixels 266.

It should be noted that, the larger the distribution density of the first pixels 226 in the first display area 220 of the display device 20 is, the more the first pixels 226 are in a unit area, the higher the resolution is, and the better the display effect is provided, and considering the production process of the display device 20, the sizes of the first pixels 226 in the first display area 220 and the third driving unit 228 for driving the first pixels 226 correspond to each other. The plurality of third driving units 228 further require a plurality of control lines to be connected to a driving chip of the display device 20, the driving chip controls each of the third driving units 228 through the plurality of control lines, the plurality of control lines are arranged among the plurality of third driving units 228, and the first pixels 226 have a space therebetween, the space being arranged corresponding to the control lines. The control line has a certain line width, which is needed to meet the impedance requirements and the product technology. For example, the pixel density of the first display region 220 may reach 400ppi or more, the sizes of the first pixel 226 and the third driving unit 228 of the first display region 220 are substantially equal, the third driving unit 228 is correspondingly disposed under the first pixel 226, and the plurality of control lines are disposed between the plurality of third driving units 228 and correspondingly disposed under the spacing space between the first pixels 226. The third driving unit 228 and the control lines connected thereto cover substantially the entire space and it is difficult to accommodate other components.

The size of the third pixels 266 of the third display area 260 is larger than the size of the first pixels 226 of the first display area 220, the spacing distance between the third pixels 266 is positively correlated with the size of the third pixels 266, if the second driving unit 268 and the third driving unit 228 are the same driving circuit, the size of the second driving unit 268 is equal to or slightly larger than the size of the third driving unit 228, the line width of the control line connected to the second driving unit 268 is substantially equal to the line width of the third driving unit 228, and the size of the second driving unit 268 of the third display area 260 is smaller than the size of the third pixels 266, so that one layer of the second driving unit 268 disposed in the third display area 260 has a receiving space which can be used for receiving the first driving unit 248 driving the second pixels 246 of the second display area 240. One third pixel 266 of the third display region 260 may be disposed corresponding to one second driving unit 268 and at least one first driving unit 248. Illustratively, the size of the third pixel 266 is 4 times that of the first pixel 226, and one third pixel 266 of the third display region 260 may be disposed corresponding to one second driving unit 268 and three first driving units 248. In another example, the size of the third pixel 266 is 2 times that of the first pixel 226, and one third pixel 266 of the third display region 260 may be disposed corresponding to one second driving unit 268 and one first driving unit 248. In another example, the size of the third pixels 266 is 1.5 times that of the first pixels 226, and one third pixel 266 of the third display region 260 may be disposed corresponding to one second driving unit 268 and one half of the first driving unit 248, that is, one first driving unit 248 is disposed corresponding to the third pixels 266 of two third display regions 260.

The first driving unit and the second driving unit disposed in the third display region may also adopt another arrangement. Specifically, referring to fig. 11, fig. 11 is a schematic diagram of a fourth partial structure of the display device according to the embodiment of the present application. The plurality of second driving units 268 driving the third pixels 266 of the third display area 260 may be collectively disposed, the plurality of second driving units 268 of the third display area 260 may be collectively disposed at a position distant from the third display area 260, and the plurality of second driving units 268 disposed at the third display area 260 may be collectively disposed between the plurality of first driving units 248 and the plurality of third driving units 228 of the first display area 220.

The first driving unit 248 is disposed under the third pixel of the third display region 260 adjacent to the second display region 240, and the second driving unit 268 is disposed under the third pixel of the third display region 260 far from the second display region 240. For example, the size of the third pixel is 4 times that of the first pixel, 4 first driving units 248 are correspondingly disposed under one third pixel of the third display area 260 adjacent to the second display area 240, and 4 second driving units 268 are correspondingly disposed under one third pixel of the third display area 260 far away from the second display area 240.

The plurality of second pixels of the second display region and the plurality of third pixels of the third display region may be disposed in a pixel unit. Specifically, referring to fig. 12, fig. 12 is a schematic view illustrating a first structure of a second pixel in a second display region in a display device according to an embodiment of the present disclosure. The plurality of second pixels 246 of the second display region may be divided into a plurality of pixel units 244, the second display region including the plurality of pixel units 244, each pixel unit 244 including at least three different color pixels. One pixel unit 244 of the second display region may display a mixed color, and one pixel unit 244 may display a desired color as needed. For example, one pixel unit 244 includes R, G, B three color second pixels 246, which can display various colors of red, green, blue, white, pink, cyan, etc., as desired. The same color second pixels 246 of at least two pixel units 244 in the second display region are connected in parallel to form a pixel set 242. For example, 4 pixel units 244 may form 3 pixel sets 242, specifically, 4 red second pixels 246 are connected in parallel to form one pixel set 242, 4 green second pixels 246 are connected in parallel to form one pixel set 242, 4 blue second pixels 246 are connected in parallel to form one pixel set 242, and the 4 pixel units 244 form one display unit. It should be noted that one pixel unit may further include a second pixel of multiple colors such as R, G, B, W or R, G, B, Y.

The parallel connection of the second pixels 246 may be formed by a direct connection of the second pixels 246. For example, the plurality of second pixels 246 are connected in parallel by the same material as the material thereof or connected in parallel by a connection line of other material. The second pixels 246 in parallel may also be connected in parallel in other ways. Specifically, the second display region further includes a plurality of metal anodes, one metal anode is disposed corresponding to and electrically connected to one second pixel 246, and the parallel connection of the metal anodes can be implemented through the parallel connection of the pixels. Of course, the plurality of second pixels 246 connected in parallel in one pixel set 242 may be a plurality of same-color second pixels 246. For example, the second pixels 246 of one set of pixels 242 are all red pixels or green pixels or blue pixels.

The second display region includes gate lines (not shown) and data lines, which cooperate with the first driving unit to drive each of the second pixels 246. The gate lines and the data lines may be disposed on different layers and staggered, for example, the gate lines are arranged in rows and the data lines are arranged in columns. The second pixels 246 of the second display region may be arranged in one of a standard RGB arrangement, a Pentile arrangement, or a Delta arrangement. Note that the data line is not in the same layer as the second pixel 246.

When the plurality of second pixels 246 of the same color connected in parallel are parallel to the data line and arranged in a row, a first driving signal line 2462 is disposed between two rows of the second pixels 246, the first driving signal line 2462 is parallel to the data line, and is electrically connected to the second pixels 246 through a second driving signal line 2464 perpendicular to the first driving signal line 2462. Different pixel arrangements have different parallel arrangements, as shown in particular in fig. 12 and 13.

When a plurality of the second pixels of the same color are arranged in parallel, the second pixels have different parallel connection modes. Specifically, referring to fig. 14 and fig. 15, fig. 14 is a third structural schematic diagram of a second pixel in a second display area in the display device provided in the embodiment of the present application, and fig. 15 is a fourth structural schematic diagram of the second pixel in the second display area in the display device provided in the embodiment of the present application. When the plurality of the second pixels 246 of the same color connected in parallel are arrayed, two adjacent second pixels 246 of the same color parallel to the data line direction are connected in parallel by a first driving signal line 2462, the first driving signal line 2462 is parallel to the data line, and adjacent second pixels 246 of the same color perpendicular to the data line direction are connected in parallel by a second driving signal line 2464, wherein the second driving signal lines 2464 connecting the second pixels 246 of different colors are arranged at intervals.

For convenience of understanding, fig. 14 and 15 are taken as an example for explanation, fig. 14 shows a schematic diagram of the second pixels 246 of the second display area in a standard RGB arrangement, and fig. 15 shows a schematic diagram of the second pixels 246 of the second display area in a Delta arrangement. The plurality of second pixels 246 are arranged in an array, R, G, B second pixels 246 of the same color are all arranged in an array, and a first driving signal line 2462 is arranged beside two adjacent pixels of the same color in a column and is connected in parallel through a second driving signal line 2464 perpendicular to the first driving signal line 2462. Specifically, a first driving signal line 2462 is provided next to the second pixels of the same color adjacent to the column and connected in parallel via a second driving signal line 2464 perpendicular thereto. Among the same-color second pixels adjacent in a row, the B second pixels directly connect the two first driving signal lines 2462 in parallel at one end, the R second pixels directly connect the two first driving signal lines 2462 in parallel at the other end, the G second pixels are connected in parallel through the third driving signal lines 2466, the third driving signal lines 2466 bypass the B second pixels and the R second pixels disposed between the two columns of the G second pixels, and the driving signal lines of the R second pixels are connected at intervals. It should be noted that the second pixels in the second display area may also be arranged in a similar parallel manner according to Pentile, and are not described herein again.

When the parallel connection of the plurality of second pixels with the same color is vertical to the data line, the second pixels have different parallel connection modes. Specifically, referring to fig. 16, fig. 16 is a schematic diagram illustrating a fifth structure of a second pixel in a second display area in a display device according to an embodiment of the present disclosure. The second pixels 246 of the second display region are arranged in a standard RGB arrangement or a Pentile arrangement. The plurality of second pixels 246 of the same color connected in parallel are perpendicular to the data line, a first driving signal line 2462 is disposed along a direction perpendicular to the data line, the first driving signal line 2462 is electrically connected to the second pixels 246 through a second driving signal line 2464 perpendicular to the first driving signal line 2462, wherein the second driving signals connected to the second pixels 246 of different colors are disposed at intervals. For convenience of understanding, as will be described in detail below by taking fig. 14 as an example, a first driving signal line 2462 is disposed at each of two sides of a plurality of same-color second pixels 246, a first driving signal line 2462 is disposed at the middle, a plurality of G second pixels 246 are electrically connected to the first driving signal line 2462 through a plurality of second driving signal lines 2464 perpendicular to the first driving signal line 2462, so as to implement parallel connection of a plurality of G communication pixels, a plurality of B second pixels 246 are implemented in parallel connection in a similar connection manner to the G second pixels 246, the first driving signal line 2462 electrically connected to the R second pixels 246 is disposed at an end portion, the second display region further includes a third driving signal line 2466 connecting the plurality of R second pixels 246 in parallel, and the third driving signal line 2466 connects the plurality of R second pixels 246 in parallel avoiding driving signals electrically connected to the G second pixels 246 and the B second pixels 246. Specifically, the third drive signal line 2466 bypasses the G second pixel 246 along a side opposite the second drive signal line 2464 connected to the G second pixel 246, and also bypasses the B second pixel 246 along a side opposite the second drive signal line 2464 connected to the B second pixel 246. It should be noted that the second pixels in the second display area may also be arranged in a similar parallel manner according to Pentile, and are not described herein again.

It is understood that the first driving unit driving the second pixel of the second display region in the embodiment of the present application may be one of 7T1C, 5T1C, or 2T1C as needed.

For example, in order to improve the light transmittance of the second display region, the first driving unit disposed in the second display region may be a simpler driving circuit than the third driving unit of the first display region, and the first driving unit may include a smaller number of thin film transistors than the third driving unit. The number of the light-tight thin film transistors in the first driving unit is less, the light-tight part in the second display area is less, and the light transmittance of the second display area is higher. For example, the third driving unit is a 7T1C driving circuit, and the first driving unit may be a 5T1C or 2T1C driving circuit.

In another example, in order to conveniently dispose the first driving unit in the third display area, the first driving unit for driving the second pixel of the second display area may be a driving circuit which is simpler than the third driving unit of the first display area, so as to reduce the space occupied by the first driving unit, reduce the area of the third display area, increase the proportion of the first display area in the display device, and improve the overall display effect of the display device. The second driving unit of the third display region may be the same as the first driving unit of the second display region, may be the same as the third driving unit of the first display region, or may be different from both the first driving unit and the third driving unit. For example, the third driving unit of the first display region may be 7T1C, the second driving unit of the third display region may be 5T1C, and the first driving unit of the second display region may be 2T 1C. Since the third driving unit of 7T1C includes a larger number of TFTs and occupies a larger space, although it has a good display effect, it is difficult to leave a larger gap space to accommodate the first driving unit. The second driving unit of 5T1C can have better display effect, and at the same time, the occupied space is reduced because of using less driving circuits of TFTs to accommodate the simplest first driving unit of the driving circuit.

Besides that the second pixels of the same color of different second pixel units are connected in parallel and form the pixel set, the second pixel in one second pixel unit and the second pixel of at least one other second pixel unit can be connected in parallel and form the pixel set. For example, the R pixel of one second pixel unit and the G and B pixels of another second pixel unit are connected in parallel to form a pixel set. For another example, the R pixel of one second pixel unit, the G pixel of another second pixel unit, and the B pixel of the third second pixel unit are connected in parallel to form a pixel set. The color mixing display can be performed according to the needs, for example, the second display area is displayed by a specific icon, and the second pixels in the second display area can be connected in parallel according to the specific icon.

In addition, the second pixel set can also be formed by connecting at least two second pixels with different colors in the same pixel unit in parallel. As shown in fig. 17, the R pixels, the B pixels, and the G pixels in the second pixel set 244 are connected in parallel to form a pixel set 242. The color mixing display can be performed according to the needs, for example, the second display area is displayed by a specific icon, and the second pixels in the second display area can be connected in parallel according to the specific icon. For example, the second display region displays a signal icon (4G, 5G, WIFI, etc.), an alarm clock icon, and the like. The second display area only needs to display white or black alarm clock icons and the like. Note that, in this case, only the second pixels of two colors may be connected in parallel, and the second pixels of the other color may be driven individually.

For convenience of understanding, the first driving circuit 2T1C will be described as an example. Referring to fig. 18, fig. 18 is a circuit schematic diagram illustrating a plurality of second pixels in a second display area of a display device according to an embodiment of the present disclosure connected in parallel. Where VDADA is the data line, SEL is understood to be the gate line, VDD is the supply line, and OLED is the second pixel. The figure shows an embodiment in which 3 second pixels are connected in parallel, and it is understood that other numbers of second pixels, such as 2, 4, 9, 16, etc., may be connected in parallel as needed.

The first driving unit may be disposed in a non-display region outside the display region, in addition to the display region of the display device. Referring to fig. 19 in detail, fig. 19 is a schematic view of a fifth partial structure of a display device according to an embodiment of the present application. The display device 20 may further include a non-display area 280, and the first driving unit 248 driving the second pixels 246 of the second display area 240 may be further disposed in the non-display area 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 in the case of the full-screen display device 20, the edge of the display device 20 still has a non-display area, and the non-display area 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 second display area 240 is small, the number of the second pixels 246 in the second display area 240 is small, and the plurality of second pixels 246 of the second display area 240 are connected in parallel, and the number of the first driving units 248 for driving the second pixels 246 of the second display area 240 is small, the first driving units 248 can be disposed at the black edge position, so that the light transmittance of the second display area 240 is improved, and the first display area 220 or the third display area 260 is not affected. A plurality of first driving units 248 need to be disposed corresponding to the second pixels 246 of the second display area 240, and the plurality of first driving units 248 may be all disposed at black edge positions. In order to better accommodate all the first driving units 248 for the black edge position, simpler first driving units 248 may be used, for example, the first driving units 248 may use 2T1C, 5T1C, etc. driving circuits, the number of Thin Film Transistors (TFTs) in each first driving unit 248 may be smaller, and the space required by a single first driving unit 248 may be smaller. The distribution density of the second pixels 246 in the second display area 240 can be set lower, so that the total number of the first driving units 248 in the second display area 240 is smaller. It should be noted that the plurality of first driving units 248 may also be partially disposed in the non-display area 280, and partially disposed in the second display area 240 or the third display area 260.

It should be noted that, in the embodiment of the present application, the first display area may be an active matrix driving (AMOLED) display area, and the second display area may be an active matrix driving (AMOLED) display area or a passive matrix driving (PMOLED) display area. The area of the second display area is far smaller than that of the first display area, the first display area can be used as a main display area of the display device, and the second display area can be used as an auxiliary display area of the display device. The PMOLED has a lower display effect than the AMOLED, but the second display area may be located at the edge of the display device, and the importance of the displayed content is low, so the PMOLED may be used in the second display area. The second display area driven in a passive mode only needs one Thin Film Transistor (TFT) for driving, the number of the light-tight thin film transistors is very small, and the light transmittance of the second display area can be greatly improved. Of course, in order to make the display effect of the second display region close to that of the first display region, the second display region may also be active matrix driving (AMOLED). The third display area may select an active driving (AMOLED) display area or a passive driving (PMOLED) display area as desired. Since the physical structures of the pixels of the third display region and the second display region are the same, the third display region and the second display region may be the same driving manner. If the area of the third display area is larger, the third display area and the first display area may be both active matrix driving (AMOLED) display areas for better display effect.

The shape and size of the second display area can be set according to the camera, and the transition area between the second display area and the third display area and the transition area between the second display area and the first display area needs special treatment. Referring to fig. 20 to 22, fig. 20 is a schematic view of a sixth partial structure of a display device according to an embodiment of the present application, fig. 21 is an enlarged schematic view of a portion Z1 of the display device in fig. 20, and fig. 22 is an enlarged schematic view of a portion Z2 of the display device in fig. 20. The pixel set of the second display region 240 includes a plurality of second pixels 246, and the plurality of second pixels 246 within the pixel set may be arranged in an array. For example, the second pixels 246 within the set of pixels are arranged in 3 rows of 3 second pixels 246 each. The plurality of second pixels 246 in the second display area 240 may be all divided into different pixel sets, but the size and shape of the second display area 240 need to be set according to the camera, a part of the second pixels 246 of the second display area 240 adjacent to the third display area 260 or the first display area 220 may not be in the pixel set of the complete array arrangement, and if the part of the second pixels 246 is not displayed, the transition between the second display area 240 and the third display area 260 or the first display area 220 is not uniform. Therefore, in order to make the transition between the second display area 240 and the third display area 260 or the first display area 220 uniform, the portion of the second pixels 246 also needs to be electrically connected to the first driving unit, i.e., the portion of the second pixels 246 is also driven to display. In particular, the second display area 240 may include a plurality of regular first pixel sets 2422 and at least one irregular second pixel set 2424. The plurality of second pixels 246 in the first pixel set 2422 are arranged in a regular shape, such as 3 rows and 3 columns, 2 rows and 2 columns, 2 rows and 3 columns, 3 rows and 2 columns, 4 rows and 4 columns, and so on. The second pixel set 2424 comprises a smaller number of second pixels 246 than the first pixel set 2422, and it can be understood that the plurality of second pixels 246 of the second display area 240 first divide the plurality of first pixel sets 2422, the rest is not enough to divide the first pixel sets 2422, and the rest of the second pixels 246 are adjacent to the edge of the second display area 240. The remaining second pixels 246 are still divided according to the original division rule, and beyond the abandoning of the second display area 240, only the remaining portions are connected in parallel to form a second pixel set 2424. The second set of pixels 2424 is a set of second pixels 246 that are not in the first set of pixels 2422 at the edge of the second display area 240. For example, the first pixel set 2422 is arranged in 3 rows and 3 columns, the edge of the second display area 240 has one second pixel 246 at the i-th column, i +1 column and i +2 column of the k-th row at the k-th row, k +1 row and k +2 row, one second pixel 246 at the i-th column and i +1 column of the k +1 row and one second pixel 246 at the i-column of the k +2 row, the 6 second pixels 246 are connected in parallel to form an irregular second pixel set 2424, and the number of the second pixels 246 in each row is different. It should be noted that the number and arrangement of the second pixels 246 in the second pixel set 2424 depends on the second display region edge, and the number and arrangement of the second pixels 246 included in different second pixel sets 2424 may be different. The second pixel set 2424 may include only 1 second pixel 246 or may include a plurality of second pixels 246.

Since the second pixels 246 of the second display area 240 are physically identical to the third pixels 266 of the third display area 260, a smooth transition may be formed by the irregular transition of the second set of pixels 2424. Especially, when the edge of the second display area 240 is arc-shaped, the sharp feeling of the straight line transition and the destructive feeling of the saw-toothed display can be avoided. And a corresponding display smoothing algorithm can be set for the second pixel set 2424, and the second pixel 246 of the second pixel set 2424 is subjected to display smoothing transition processing, so that smooth transition is realized. In addition, an algorithm corresponding to a portion adjacent to the second pixel 246 may be provided in the third display region 260 and/or the first display region 220, and a smooth transition may be performed on a portion of the third display region 260 and/or the first display region 220 adjacent to the second display region 240.

It should be noted that the third display area 260 may be disposed around the second display area 240, and the second display area 240 is not adjacent to the first display area 220, so that only the transition problem between the second display area 240 and the third display area 260 needs to be considered.

The second display area 240 may also have other shapes as shown in fig. 23. The second display area 240 may also be a rounded rectangle, the light-transmitting display area may also be a regular shape such as a square, a rectangle, a diamond, a positive polygon, and the like, and the second display area 240 may also be an irregular shape. The third display area 260 may completely surround the second display area 240 or may partially surround the second display area 240.

To facilitate understanding of the display device of the embodiments of the present application. The stacked structure of the first display region of the display device will be described below. Specifically, referring to fig. 24, fig. 24 is a schematic diagram illustrating a stacked structure of a first display region in a display device according to an embodiment of the present disclosure. The first display region of the display device includes a substrate 291, a driver circuit layer 292, an anode layer 293, a light-emitting layer 294, and a common electrode layer 295, which are sequentially stacked.

The substrate 291 may serve as a platform for supporting the display device, and the substrate 291 may be made of glass, plastic, resin or other materials. For example, Polyimide (PI) may be used as the material of the substrate 291.

The driving circuit layer 292 is disposed on the substrate 291, the driving circuit layer 292 includes third driving units 228 for driving the first pixels 226 in the first display area 220, and each of the third driving units 228 includes at least one thin film transistor.

The anode layer 293 is disposed on the driving circuit layer 292 or the substrate 291, the anode layer 293 includes a first anode layer 2932, a first insulating layer 2934, and a second anode layer 2936, the first insulating layer 2934 is disposed between the first anode layer 2932 and the second anode layer 2936 to separate and insulate the first anode layer 2932 from the second anode layer 2936, the first anode layer 2932 includes a first signal line (gate line) in a first direction, the second anode layer 2936 includes a second signal line (data line) in a second direction, the first direction and the second direction may be vertically disposed, the first signal line and the second signal line are electrically connected to the third driving unit 228, respectively, and the driving chip of the display device controls the third driving unit 228 through the first signal line and the second signal line. The first signal line may be located at the same layer as the gate electrode in the second driving unit 268, and the second signal line may be located at the same layer as the drain electrode in the second driving unit 268. The anode layer 293 may further include a metal anode layer 2938, the metal anode layer 2938 is adjacent to the light emitting layer 294, a metal anode of the metal anode layer 2938 is directly adjacent to and electrically connected to the first pixel 226 of the light emitting layer 294, a second insulating layer 2939 is provided between the metal anode layer 2938 and the source electrode of the third driving unit 228, and the pixel electrode may be electrically connected to the source electrode of the third driving unit 228 through the pixel via 2937.

The light emitting layer 294 is disposed on the anode layer 293, the light emitting layer 294 includes a pixel defining layer 2942, the pixel defining layer 2942 has a plurality of pixel holes, each of the pixel holes has a first pixel 226 disposed therein, and the first pixel 226 includes an organic light emitting material.

The common electrode layer 295 is disposed over the light emitting layer 294, and the anode layer 293 and the common electrode layer 295 are disposed on both sides of the first pixel 226 and drive the first pixel 226 in common.

A planarization layer 296 may be further disposed on the common electrode layer 295, the first pixel 226 is disposed behind the pixel hole, the first pixel 226 does not fill the pixel hole, a groove may be formed after the common electrode layer 295 is disposed on the first pixel 226, and the planarization layer 296 may fill the groove and cover the entire light emitting layer 294 to protect the light emitting layer 294, etc.

A touch layer 297 may also be disposed on the planarization layer 296, and the touch layer 297 may be used to detect a user touch operation.

A polarizer (not shown) may be further disposed on the touch layer 297, and the polarizer may be used to prevent internal light from transmitting out and prevent a user from seeing internal components such as a driving unit.

It should be noted that in other embodiments, some of the structures may be added or subtracted as desired. For example, at least one of the touch layer 297 and the polarizer may be reduced. For another example, a protective layer may be added between the planarization layer 296 and the touch layer 297, and the same material as the substrate 291 may be used for the protective layer.

The second display area 240 may have a structure similar to that of the first display area 220, and reference may be made to the above embodiments, which are not described herein again. Referring to fig. 3 and fig. 4, in the second display area 240, the structures except the driving circuit layer are made of transparent materials to improve the light transmittance of the second display area. For example, the substrate, the pixel defining layer, the common electrode layer, the planarization layer, and the touch layer of the second display area 240 may be made of a light-transmitting material, and the signal lines in the anode layer may be made of a light-transmitting material such as nano-silver. The TFT of the driving circuit layer cannot be made of a light-transmitting material, and the driving circuit layer may be made of a light-transmitting material except for the TFT. It is understood that the scheme of increasing the second 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. It should be noted that the substrate, the pixel defining layer, the common electrode layer, the planarization layer, and the touch layer of the second display area 240 may be made of the same light-transmitting material as that of the first display area 220, and for example, the substrate may be made of a light-transmitting material such as glass or resin. The driving circuit layer of the second display area 240 may be provided with a first driving unit having a circuit that is simplified than that of the third driving unit 228. For example, the third driving unit 228 employs a 7T1C circuit, the first driving unit employs a 2T1C circuit, because the TFTs are opaque, the number of TFTs of the first driving unit is smaller, the area of the first driving unit that is opaque is naturally smaller, and the second display area 240 has a higher light transmittance than the first display area 220.

Referring to fig. 8 and 9, the second display area 240 may have a different structure from the first display area 220. Specifically, the second display region 240 is mainly different from the first display region 220 in a driving circuit layer and/or a light emitting layer. In each layer structure in the second display area 240, except for the driving circuit layer, a transparent material is used to improve the light transmittance of the second display area 240. The driving circuit layer of the second display area 240 may not be provided with the first driving unit. The first driving unit is disposed on the driving circuit layer of the first display area 220 or the third display area 260, or disposed on the edge of the display device 20, where the edge is a non-display area, which can also be understood as a black edge of the display device 20, so as to implement a structure that the second display area 240 does not have a light-tight property. The circuit of the first driving unit driving the second pixel of the second display region 240 may be reduced as compared to the circuit of the third driving unit 228. For example, the third driving unit 228 employs a 7T1C circuit, the first driving unit employs a 2T1C circuit, because the TFTs are opaque, the number of TFTs of the first driving unit is smaller, the area of the first driving unit that is opaque is naturally smaller, and the second display area 240 has a higher light transmittance than the first display area 220.

The light emitting layer of the second display region 240 includes second pixels, and the light emitting layer of the second display region 240 has a similar structure to the light emitting layer 294 of the first display region 220, but the distribution density of the second pixels may be smaller than that of the first pixels 226, the distribution density of the second pixels is smaller, and the light transmittance of the first display region 220 is naturally greater. The lower distribution density of the second pixels 246 can be achieved by increasing the interval between the second pixels 246, increasing the size of the second pixels 246, or both increasing the interval between the second pixels 246 and increasing the size of the second pixels 246.

The size and distribution density of the second pixels of the light emitting layer of the second display region 240 are the same as those of the second pixels of the third display region 260. However, at least two second pixels in the second display area 240 are connected in parallel and driven by one first driving unit, so that the number of first driving units required for the second display area 240 can be reduced. The parallel connection of the plurality of second pixels may be implemented by a parallel connection of metal anodes of the anode layer.

The polarizer corresponding to the second display area 240 may have a first polarizing portion, which may be a through hole or a transparent material. For example, a through hole is formed corresponding to the second display area 240, and then the through hole is filled with a transparent material to form the first polarizer. For another example, a through hole is formed corresponding to the second display area 240, and then the through hole is filled with a high-transmittance low-polarization material to form a first polarization part, so that the first polarization part can achieve both the function of high transmittance and the function of preventing light from being reflected, and a user can see the internal structure.

It should be noted that the physical structures of the pixels in the third display area 260 and the second display area 240 are the same, and the size of the third pixel in the third display area 260 and the size of the second pixel in the second display area 240 are the same, and the arrangement manner is the same, so the third display area 260 may adopt a structure similar to that of the second display area 240. The main difference is at least one of the driving circuit layer, the anode layer and the light emitting layer. The plurality of second pixels of the second display region 240 are connected in parallel, which may be implemented by connecting the second pixels in the light emitting layer in parallel, or by connecting the metal anodes in the anode layer in parallel. The first driving unit 248 driving the second pixels of the second display region 240 may be disposed at the driving circuit layer of the third display region 260.

In some embodiments, the driving circuit layer of the third display area includes a first driving layer and a second driving layer, which are stacked, the first driving circuit is disposed on the first driving circuit layer, the second driving circuit is disposed on the second driving circuit layer, the second driving unit layer is provided with a plurality of via holes, and the plurality of first driving units are electrically connected to the pixel set in the second display area through signal lines passing through the plurality of via holes, and are configured to drive the second pixel in the pixel set to display.

The embodiment of the present application further provides a display device, and the display device of the present application is mainly different from the display device in the above embodiments in the pixels of the second display area and the third display area. Specifically, referring to fig. 25, fig. 25 is a schematic view of an eighth partial structure of a display device according to an embodiment of the present application. The display device 20 of the present embodiment includes a first display area 220, a second display area 240, and a third display area 260. The third display area 260 connects the first display area 220 and the second display area 240. The second display area 240 may be disposed between the first display area 220 and the second display area 240. The second display area 240 and the first display area 220 may not be directly connected but connected through the third display area 260; the second display area 240 may also be directly adjacent to the first display area 220, that is, a part of the edge of the second display area 240 is adjacent to the third display area 260, or a part of the edge is adjacent to the first display area 220.

The first display region 220 includes a plurality of first pixels 226, the second display region 240 includes a plurality of second pixels 246, and the third display region 260 includes a plurality of third pixels 266. The second pixels 246 of the second display area 240 and the first pixels 226 of the first display area 220 have the same physical structure, and it can also be understood that the second pixels 246 of the second display area 240 and the first pixels 226 have the same size and the same arrangement. The third pixels 266 of the third display region 260 are larger in size than the second pixels 246 of the second display region 240. The second display region 240 includes a plurality of pixel sets 242, and each pixel set 242 includes at least two second pixels 246 connected in parallel to each other.
