The electronic equipment can comprise a display device and a camera, and a lens of the camera is arranged towards the display device. Therefore, the camera can acquire the external light signal penetrating through the display device for imaging. It can be understood that the conventional display device has low light transmittance, and thus the camera head has poor imaging effect through the conventional display device. In view of this, the embodiment of the application can set the display device in a partition manner, for example, the light transmittance of the area of the display device corresponding to the camera is set to be greater than that of other areas of the display device, so that the imaging effect of the camera can be improved.

Fig. 1 shows an example in which the electronic apparatus is a mobile phone, wherein the electronic apparatus 10 comprises a display device 20. The display device 20 includes a first display region 220 and a second display region 240, and the light transmittance of the second display region 240 is greater than that of the first display region 220. For example, the light transmittance of the second display region 240 may be greater than 60%, for example, 80%; the light transmittance of the first display region 220 is less than 20%, for example, 10%. 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 is also 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 ambient light signal transmitted through the second display area 240 of the display device 20 and form an image according to the acquired ambient light signal. Therefore, a channel for imaging by the camera 60 does not need to be separately arranged on the display device 20, so that the display area of the display device 20 is complete, and the screen occupation ratio of the display device 20 is improved. The camera 60 may be a front camera of the electronic device, and the camera 60 may be configured to obtain images such as a self-photograph of the user through the second display area 240 of the display apparatus 20.

The display device 20 will be described in detail below for a more complete understanding of the display device according to the embodiment of the present application.

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 partial 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.

Referring to fig. 3 and fig. 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, and the second display area 240 includes a plurality of second pixels 246. It is understood that the size of the second pixels 246 may be larger than the size of the first pixels 226, such that the distribution density of the second pixels 246 is smaller than the distribution density of the first pixels 226. Wherein, the pitch between two adjacent second pixels 246 is positively correlated with the size of the second pixels 246. That is, the larger the size of the second pixel 246, the larger the separation distance between two adjacent second pixels 246. Therefore, the distribution density of the second pixels 246 of the second display area 240 is less than the distribution density of the first pixels 226 of the first display area 220. That is, the number of the second pixels 246 is small in the same area, so that the light transmittance of the second display region 240 can be increased compared to that of the first display region 220.

It is understood that the size of the second pixels 246 may be four times the size of the first pixels 226, such that the area of each second pixel 246 in the second display area 240 is the same as the area of four first pixels 226 in the first display area 220, and the arrangement of the second pixels 246 in the second display area 240 may be the same as the arrangement of the first pixels 226 in the first display area 220, thereby facilitating the pixel layout of the first display area 220 and the second display area 240.

It is understood that two or more second pixels 246 may be connected in parallel to form a pixel set 242 in the second display region 240, so that each pixel set 242 may share one driving signal line to reduce the number and total area of the driving signal lines. Considering that the driving signal lines may be non-light-transmissive metal traces, reducing the number of the driving signal lines may improve the light transmittance of the second display region 240, and improve the imaging effect of the camera 60. The driving signal lines may also be transparent ITO (Indium Tin Oxides), and although the light transmittance of the ITO traces is very high, a portion of the ITO traces is reduced, and the light transmittance of the second display region 240 may also be improved to improve the imaging effect of the camera 60.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a driving circuit corresponding to a pixel of the display device in fig. 4. The display device 20 further includes a plurality of first driving units 228 and a plurality of second driving units 248.

Wherein the plurality of first driving units 228 are disposed in the first display area 220, and particularly, may be disposed on a non-display side of the first display area 220. It is understood that the non-display side of the first display area 220 is a side of the first display area 220 where no information is displayed, that is, a side of the first display area 220 facing the inside of the electronic device 10. Each of the first driving units 228 is electrically connected to one or more of the first pixels 226 to drive the one or more first pixels 226. The first driving unit 228 drives the first pixel 226 electrically connected to the first driving unit 228 in an active driving manner. That is, the first display area 220 is an Active Matrix Organic Light Emitting Diode (AMOLED) display area.

The plurality of second driving units 248 are disposed in the second display area 240, and particularly, may be disposed on a non-display side of the second display area 240. It is understood that the non-display side of the second display area 240 is a side of the second display area 240 where no information is displayed, that is, a side of the second display area 240 facing the inside of the electronic device 10. Each of the second driving units 248 is electrically connected to one or more of the second pixels 246 to drive the one or more of the second pixels 246. The second driving unit 248 drives the second pixel 246 electrically connected to the second driving unit 248 by an active driving method. That is, the second display area 240 is an Active Matrix Organic Light Emitting Diode (AMOLED) display area.

Referring to fig. 6, fig. 6 is a schematic diagram of a first structure of a pixel and a first driving unit in a first display area in a display device according to an embodiment of the present disclosure. Each of the first driving units 228 is electrically connected to one of the first pixels 226 to drive the one of the first pixels 226. That is, each of the first driving units 228 is used to drive one of the first pixels 226.

It can be understood that, in general, one first pixel 226 may be driven by each first driving unit 228, so as to improve the control accuracy when controlling the display of the first display area 220.

Referring to fig. 7, fig. 7 is a schematic diagram of a second structure of a pixel and a first driving unit in a first display area in a display device according to an embodiment of the present disclosure. Wherein the number of the first driving units 228 is smaller than the number of the first pixels 226. Each first driving unit 228 is electrically connected to at least two first pixels 226 to drive the at least two first pixels 226. Also, the at least two first pixels 226 electrically connected to the same first driving unit 228 are connected in parallel. That is, each of the first driving units 228 is used to drive at least two first pixels 226, so that the number of the first driving units 228 can be reduced. For example, as shown in fig. 7, each of the first driving units 228 may be electrically connected to 3 first pixels 226 to drive the 3 first pixels 226. The 3 first pixels 226 electrically connected to the same first driving unit 228 may be connected in parallel.

Referring to fig. 8, fig. 8 is a schematic diagram of a first structure of a pixel and a second driving unit in a second display area in a display device according to an embodiment of the present disclosure. Each of the second driving units 248 is electrically connected to one of the second pixels 246 to drive the one of the second pixels 246. That is, each of the second driving units 248 is used to drive one of the second pixels 246.

It can be understood that, in general, one second pixel 246 can be driven by each second driving unit 248, thereby improving the control accuracy when controlling the display of the second display area 240.

Referring to fig. 9, fig. 9 is a schematic diagram of a second structure of a pixel and a second driving unit in a second display area in a display device according to an embodiment of the present disclosure. Wherein the number of the second driving units 248 is smaller than the number of the second pixels 246. Each second driving unit 248 is electrically connected to at least two second pixels 246 to drive the at least two second pixels 246. Also, the at least two second pixels 246 electrically connected to the same second driving unit 248 are connected in parallel. That is, each of the second driving units 248 is used to drive at least two second pixels 246, so as to reduce the number of the second driving units 248, thereby facilitating to improve the light transmittance of the second display region 240. For example, as shown in fig. 9, each second driving unit 248 may be electrically connected to 3 second pixels 246 to drive the 3 second pixels 246. The 3 second pixels 246 electrically connected to the same second driving unit 248 may be connected in parallel.

Here, it is understood that each second driving unit 248 may be disposed opposite to one second pixel 246, and the second driving units 248 may be disposed opposite to sides or corners of the second pixels 246. That is, the orthographic projection of each of the second driving units 248 on the second pixel 246 opposite to the second driving unit 248 is located at the side or the corner of the second pixel 246.

As can be appreciated, since the second driving unit 248 includes opaque electronic devices, such as Thin Film Transistors (TFTs), when the second driving unit 248 is disposed opposite to the side edges or the corners of the second pixels 246, the influence of the second driving unit 248 on the light transmittance of the second display area 240 can be reduced, so that the light transmittance of the second display area 240 can be improved, and the imaging effect of the camera head when acquiring the external light signals transmitted through the second display area 240 for imaging can be improved.

Referring to fig. 10, fig. 10 is a schematic view illustrating a first structure of a pixel in a second display area of a display device according to an embodiment of the present disclosure. The plurality of second pixels 246 of the second display region 240 may be divided into a plurality of pixel units 244, and each pixel unit 244 includes at least three second pixels 246 of different colors. Each of the pixel units 244 can display a mixed color, so that each pixel unit 244 can display a desired color according to the requirement. For example, the pixel unit 244 may include R, G, B second pixels 246 of three colors, so that various colors of red, green, blue, white, pink, cyan, etc. may be displayed as desired. Wherein the same-color second pixels 246 of at least two of the pixel units 244 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 (R) second pixels 246 are connected in parallel to form a pixel set 242, 4 green (G) second pixels 246 are connected in parallel to form a pixel set 242, 4 blue (B) second pixels 246 are connected in parallel to form a pixel set 242, and the 4 pixel units 244 form a display unit. It should be noted that one pixel unit 244 may further include a second pixel 246 with 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 connection line as the material thereof or connected in parallel by the connection line of other material. The second pixels 246 in parallel may also be connected in parallel in other ways. Specifically, the second display area 240 may include a plurality of metal anodes, each of which is disposed opposite to and electrically connected to one of the second pixels 246. Wherein the parallel connection of the plurality of second pixels 246 may be achieved by a parallel connection of the metal anodes. That is, in the second display area 240, at least two second pixels 246 electrically connected to the same second driving unit 248 may be connected in parallel through one metal anode, so that one second driving unit 248 simultaneously drives at least two second pixels 246 connected in parallel.

It is understood that in the second display area 240, each of the second driving units 248 may be configured to drive at least two second pixels 246 of one pixel unit 244, and each of the second driving units 248 may also be configured to drive at least two second pixels 246 of one pixel set 242. The number of the second driving units 248 may be one fourth of the number of the second pixels 246, that is, the number of the second pixels 246 is four times of the number of the second driving units 248. Each of the second driving units 248 is electrically connected to four of the second pixels 246 to drive the four of the second pixels 246. For example, each of the second driving units 248 may be electrically connected to four second pixels 246 of one of the pixel sets 242 to drive the four parallel-connected second pixels 246 of one of the pixel sets 242.

It is understood that the four second pixels 246 electrically connected to the same second driving unit 248 may be pixels of the same color, that is, the four second pixels 246 driven by each second driving unit 248 may be pixels of the same color. For example, the four second pixels 246 driven by one second driving unit 248 may all be blue (B) pixels.

Of course, the four second pixels 246 electrically connected to the same second driving unit 248 may also include pixels with different colors, that is, the four second pixels 246 driven by each second driving unit 248 may include pixels with different colors, for example, pixels with at least three different colors. For example, the four second pixels 246 driven by one second driving unit 248 may include R, G, B, R color pixels, or may include R, G, B, W color pixels, or may also include R, G, B, Y color pixels, and so on.

The second display region 240 includes a gate line (not shown) and a data line, and the gate line, the data line and a plurality of second driving units cooperate 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 240 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 arrangement modes have different parallel connection modes, specifically as shown in fig. 10 and fig. 11, where fig. 11 is a second structural schematic diagram of a pixel in a second display region in the display device provided in the embodiment of the present application.

When a plurality of the second pixels 246 of the same color are arrayed in parallel, the second pixels 246 have different parallel connection modes. Referring to fig. 12 and 13, fig. 12 is a third schematic structural diagram of a pixel in a second display area in a display device according to an embodiment of the present disclosure, and fig. 13 is a fourth schematic structural diagram of a pixel in a second display area in a display device according to an embodiment of the present disclosure.

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, taking fig. 12 and 13 as an example for explanation, fig. 12 shows a schematic diagram of the second pixels 246 of the second display area in a standard RGB arrangement, and fig. 13 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.

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. 14, fig. 14 is a schematic diagram illustrating a fifth structure of a 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 the driving signal lines 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.

In addition to the second pixels 246 of the same color of different pixel units 244 being connected in parallel and forming the pixel set 242, a second pixel 246 of one pixel unit 244 and a second pixel 246 of a different color of at least one other pixel unit 244 may be connected in parallel and form the pixel set 242. For example, the R pixel of one pixel unit 244 and the G pixel, B pixel of another pixel unit 244 are connected in parallel to form a pixel set 242. For another example, the R pixel of one pixel unit 244 and the G pixel of another pixel unit 244 and the B pixel of yet another pixel unit 244 are connected in parallel to form a pixel set 242.

In addition, the pixel set 242 may be formed by connecting at least two second pixels 246 of different colors in the same pixel unit 244 in parallel. As shown in fig. 15, fig. 15 is a sixth schematic structural diagram of a pixel in a second display area in a display device according to an embodiment of the present application. Wherein R pixels, B pixels, and G pixels in one pixel set 244 are connected in parallel to form a pixel set 242. Note that, only the second pixels 246 of two colors may be connected in parallel, and the second pixels 246 of the other color may be driven individually.

It can be understood that, in the display device provided in the embodiment of the present application, the first driving unit 228 and the second driving unit 248 may be set to be one of 7T1C, 5T1C, 2T1C and 1T as needed. Where T refers to a Thin Film Transistor (TFT) and C refers to a capacitor. It should be noted that, the greater the number of TFTs included in each driving unit, the more accurate the driving of the pixel display can be controlled; accordingly, the smaller the number of TFTs included in each driving unit, the lower the control accuracy when driving the pixel display. On the other hand, however, since the TFT is opaque or the light transmittance of the TFT is understood to be low, the greater the number of TFTs included in each driving unit, the lower the light transmittance of the pixel disposed opposite to the driving unit; accordingly, the smaller the number of TFTs included in each driving unit, the higher the light transmittance of the pixel disposed opposite to the driving unit.

For example, in order to improve the light transmittance of the second display region 240, the second driving unit 248 disposed in the second display region 240 may be a more simplified driving circuit than the first driving unit 228 of the first display region 220. That is, each of the second driving units 248 includes a smaller number of Thin Film Transistors (TFTs) than any of the first driving units 228. Therefore, the number of TFTs in the second driving unit 248 that do not transmit light is smaller, so that the light transmittance of the second display region 240 is higher, that is, the light transmittance of the second display region 240 can be increased. For example, the second driving unit is a 7T1C driving circuit, and the first driving unit may be a 5T1C or 2T1C driving circuit.

Referring to fig. 16 and 17, fig. 16 is a circuit schematic diagram of a second driving unit in the display device according to the embodiment of the present disclosure, and fig. 17 is a circuit schematic diagram of a first driving unit in the display device according to the embodiment of the present disclosure.

In fig. 16, the second driving unit 248 is a 1T driving circuit, that is, the second driving unit 248 includes 1 TFT. Here, VDATA is a data line, SEL is a gate line, T1 is a TFT, and OLED2 is a second pixel. The figure shows the way that 3 second pixels are connected in parallel, and it is understood that other numbers of second pixels, such as 2, 4, 9, 16 second pixels, etc., can be connected in parallel as required.

In fig. 17, the first driving unit 228 is a driving circuit of 2T1C, that is, the first driving unit 228 includes 2 TFTs and 1 capacitor. Here, VDATA is a data line, SEL is a gate line, VDD is a power supply line, T1 and T2 are both TFTs, Cs is a capacitor, and OLED1 is a first pixel. The figure shows the way that 3 first pixels are connected in parallel, and it is understood that other numbers of first pixels, such as 2, 4, 9, 16 first pixels, etc., can be connected in parallel as required.

It should be noted that, although fig. 16 shows that the second driving unit 248 includes 1 TFT, and fig. 17 shows that the first driving unit 228 includes 2 TFTs, other configurations may be adopted in practical applications.

For example, when the number of TFTs included in each of the second driving units 248 is 1, the number of TFTs included in each of the first driving units 228 is 2, 5, or 7. That is, the second driving unit 248 is a driving circuit of 1T, and the first driving unit 228 may be a driving circuit of 2T1C or 5T1C or 7T 1C.

For another example, when the number of TFTs included in each of the second driving units is 2, the number of TFTs included in each of the first driving units is 5 or 7. That is, the second driving unit 248 is a driving circuit of 2T1C, and the first driving unit 228 may be a driving circuit of 5T1C or 7T 1C.

For another example, when the number of TFTs included in each of the second driving units is 5, the number of TFTs included in each of the first driving units is 7. That is, the second driving unit 248 is a driving circuit of 5T1C, and the first driving unit 228 is a driving circuit of 7T 1C.
