Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of display, and particularly relates to a display substrate and a display device. BACKGROUND

[0002] In a display device (such as a mobile phone) using under-screen imaging, an image acquisition unit (such as a camera) can be arranged on the back side of a display substrate (display panel) (i.e. the "back" of the display device). The area of the display substrate corresponding to the image acquisition unit is the acquisition area, and the acquisition area also has light-emitting devices (such as organic light-emitting diodes) of sub-pixels arranged therein for display.

[0003] The light-emitting devices themselves are generally opaque, so in order to ensure that the image acquisition unit can receive sufficient light for imaging, other structures (such as driving circuits for driving the light-emitting devices to emit light) that can block light in the acquisition area should be as few as possible to improve the transmittance of the acquisition area.

[0046] Glossary

[0047] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an overly literal or overly formal sense unless expressly so defined herein.

[0048] In the present application, the following technical terms should be understood as follows unless otherwise specified:

[0049] The multiple structures "are arranged in the same layer" means that the multiple structures are formed by the same material layer, so they are in the same layer in the stacking relationship, but it does not mean that the distance between them and the substrate is equal, nor does it mean that other layer structures between them and the substrate are completely the same.

[0050] In a first aspect, with reference to Figures 1 to 9 The embodiment of the present application provides a display substrate 9.

[0051] With reference to Figure 9 The display substrate 9 of the embodiment of the present application is used in a display device for under-screen imaging, that is, the back side is used to arrange an image acquisition unit 8 (such as a camera), and the image acquisition unit 8 acquires the image on the display side through the acquisition area 91 of the display substrate 9.

[0052] Among them, the back side and the display side are two opposite sides of the display substrate 9 (the display device), the back side corresponds to the "back" of the display device, and the display side corresponds to the "front" of the display device, that is, the face of the display device that the user watches.

[0053] The display substrate 9 of the embodiment of the present application comprises a display area 99, and the display area 99 has a plurality of sub-pixels 1 arranged in multiple rows and multiple columns along intersecting row directions 94 and column directions 95, respectively. Each sub-pixel 1 has a light emitting device 11; each sub-pixel 1 has a corresponding driving circuit 12; wherein,

[0054] The display substrate 9 comprises a collection area 91 located in the middle of the display area 99 along the first direction, and the collection area 91 comprises m rows and n columns of sub-pixels 1; m and n are each an integer greater than or equal to 2.

[0055] The collection area 91 is flanked by transition areas 92 along the row direction 94, and each transition area 92 comprises m rows and n / 2 columns of transition units 2; each transition unit 2 comprises: k sub-pixels 1, k local drive circuits 121 corresponding to the k sub-pixels 1 in the transition unit 2, and a transition drive circuit 122 corresponding to the sub-pixels 1 in the same row in the collection area 91; and each transition drive circuit 122 is connected to the light emitting device 11 in the corresponding sub-pixel 1 via a connection line 19.

[0056] It should be understood that the "number" of any structure (such as the sub-pixel 1, the transition unit 2, the drive circuit 12, etc.) is an integer, and therefore the selection of the numbers m, n, k, etc. in the embodiments of the present application should ensure that the corresponding structures are each an integer.

[0057] It should be understood that the "row direction 94" and the "column direction 95" above are two intersecting relative directions, and do not necessarily correspond to the shape or placement of the display substrate 9; for example, the "row direction 94" does not necessarily represent the "horizontal direction", and the "column direction 95" does not necessarily represent the "vertical direction".

[0058] Referring to Figure 1 , Figure 2 In the display substrate 9 of the embodiments of the present application, at least part of the area is a "display area 99" for displaying, and there can also be a frame area or the like outside the display area 99.

[0059] It should be understood that the display substrate 9 can be entirely the display area 99, so that the display substrate 9 can be used for a "full screen display device".

[0060] Referring to Figure 1 , in the display area 99 above, there are a plurality of sub-pixels 1 (or pixel units) arranged in an array along the row direction 94 and the column direction 95, and each sub-pixel 1 is provided with a light emitting device 11 (such as an organic light emitting diode) for emitting light, so that each sub-pixel 1 is the smallest "point" in the display substrate 9 that can independently display the required content.

[0061] Optionally, the row direction 94 and the column direction 95 are perpendicular to each other.

[0062] The row direction 94 and the column direction 95 above can be perpendicular to each other, so that the array of the sub-pixels 1 in the display area 99 is in the form of a "matrix".

[0063] In which, referring to Figure 3Each sub-pixel 1 also has a corresponding "driving circuit 12 (or pixel circuit)" to drive the light emitting device 11 in the sub-pixel 1 to emit light according to the required brightness.

[0064] Among them, the light emitting device 11 is necessarily located in its corresponding sub-pixel 1, and the driving circuit 12 is not necessarily located in its corresponding sub-pixel 1.

[0065] Among them, the above light emitting device 11 can be in the form of an organic light emitting diode (OLED), a micro light emitting diode (Micro LED), a nano light emitting diode (Mini LED), etc., which will not be described in detail here.

[0066] Among them, the form of the driving circuit 12 corresponds to the form of the light emitting device 11, such as it can be a driving circuit 12 including a storage capacitor (C) and a plurality of thin film transistors (T) (such as a 7T1C form of driving circuit).

[0067] Referring to Figure 1 , Figure 2 , in the display area 99 of the display substrate 9 of the embodiment of the present application, there is a collection area 91 located in the middle along the row direction 94, that is, there are an equal number of sub-pixels 1 outside the collection area 91 along both sides of the row direction 94.

[0068] The collection area 91 includes a plurality of rows and columns (m rows n columns) of sub-pixels 1 (a total of m*n), so it can also display.

[0069] Referring to Figure 9 , in the display device under the camera, the image collection unit 8 is arranged on the back side of the display substrate 9 and is located at a position corresponding to the collection area 91 to collect images through the collection area 91.

[0070] Referring to Figures 1 to 4 , each of the two sides of the above collection area 91 has one "transition area 92". Each transition area 92 has m rows of transition units 2 (or "pixel islands"), and each row has n / 2 transition units 2. Each transition unit 2 has a plurality (k) of sub-pixels 1 in the same row, and a plurality of driving circuits 12 (local driving circuits 121) corresponding to these sub-pixels 1. At the same time, each transition unit 2 also has a driving circuit 12 (transition driving circuit 122) corresponding to the sub-pixels 1 in the collection area 91, and the transition driving circuit 122 needs to be connected to the light emitting device 11 in the corresponding sub-pixel 1 through the connection line 19.

[0071] It should be understood that referring to Figure 1 , Figure 2In addition to the above collection area 91 and the two transition areas 92, the other part of the display area 99 can also be displayed, which is a "normal display area 93". In the normal display area 93, the light emitting device 11 and the driving circuit 12 corresponding to each sub-pixel 1 can be arranged in the sub-pixel 1.

[0072] It should be understood that the local driving circuit 121 in each transition unit 2 and the corresponding light emitting device 11, and the driving circuit 12 and the light emitting device 11 in the same sub-pixel 1 in the normal display area 93 are also electrically connected (such as through a lead or direct connection), which will not be described in detail here.

[0073] That is, the n driving circuits 12 corresponding to each row of n sub-pixels 1 of the collection area 91 are "averagely divided into" the n (n / 2 on each side) transition units 2 in the same row on both sides, so that each transition unit 2 has k sub-pixels 1, and k light emitting devices 11 and k driving circuits 12 (local driving circuits 121) corresponding to the k sub-pixels 1, and one driving circuit 12 (transition driving circuit 122) corresponding to one sub-pixel 1 in the same row in the collection area 91.

[0074] For example, assuming that the collection area 91 and the two transition areas 92 occupy N columns in the row direction 94, there are:

[0075] The total number of transition units 2 (also transition driving circuits 122) is: m*n;

[0076] The number of transition units 2 in each row in each transition area 92 is: n / 2;

[0077] The number of sub-pixels 1 (also light emitting devices 11 and local driving circuits 121) in each row in each transition area 92 is: (N-n) / 2;

[0078] The number k of sub-pixels 1 (also light emitting devices 11 and local driving circuits 121) in each transition unit 2 is: (N-n) / n;

[0079] The vertical number of driving circuits 12 (including local driving circuits 121 and transition driving circuits 122) in each transition unit 2 is: N / n.

[0080] And referring to Figure 1 Assuming that the size (height) of each sub-pixel 1 in the column direction 95 is a, and the size (width) in the row direction 94 is b, there are:

[0081] The size (height) of each transition unit 2 in the column direction 95 is: a;

[0082] The size (width) of each transition area 92 in the row direction 94 is: b*(N-n) / 2;

[0083] The size (width) of each transition unit 2 in the row direction 94 is b*(N-n) / n.

[0084] If all the drive circuits 12 (including the local drive circuit 121 and the transition drive circuit 122) in each transition unit 2 are arranged in a row along the row direction 94, the size (width) of each drive circuit 12 in the row direction 94 is b*(N-n) / N.

[0085] In general, in combination with the actual size of the sub-pixel 1, a is 40-60 μm, b is 40-60 μm, and the size of the image acquisition unit 8 is about 2.4 mm. Thus, at a PPI (pixels per square inch) of 400-600, the number of rows and columns of pixels in the acquisition area 91 is calculated to be 40-60. If a virtual pixel design is used, it is assumed that each pixel includes two sub-pixels 1 in the row direction 94, so that m is 40-60 and n is 80-120.

[0086] It can be seen that in the display substrate 9 of the embodiment of the present application, the acquisition area 91 has the light emitting device 11 but no drive circuit 12, so that the acquisition area 91 can realize display and has a high transmittance, and more light can be transmitted into the image acquisition unit 8 through the acquisition area 91, improving the image acquisition quality.

[0087] Furthermore, in the display substrate 9 of the embodiment of the present application, all the sub-pixels 1 (i.e. the light emitting device 11) are uniformly distributed, so that the display effect is good.

[0088] Meanwhile, the drive circuit 12 (the transition drive circuit 122) corresponding to each row of sub-pixels 1 in the acquisition area 91 is uniformly distributed in the same row of multiple transition units 2 in the transition area 92 on both sides; thus, on the one hand, all the transition drive circuits 122 can be connected to the corresponding light emitting device 11 through the connection line 19 extending substantially along the row direction 94, and the lead wires overlap less, facilitating connection; on the other hand, the transition drive circuits 122 are uniformly distributed as a whole, and have less influence on the local drive circuit 121, facilitating the design of the display structure.

[0089] Thus, the display substrate 9 of the embodiment of the present application can realize high transmittance of the acquisition area 91 at a high resolution (e.g. PPI of 400-600).

[0090] Optionally, all the sub-pixels 1 on both sides of the acquisition area 91 are in the transition area 92.

[0091] Reference Figure 1As a manner of the embodiment of the present application, both sides of the collection area 91 can be the transition area 92, i.e. the collection area 91 and the transition area 92 "occupy" the m rows of the display substrate 9, so that N is equal to the total column number of the sub-pixels 1.

[0092] Optionally, on the side of each transition area 92 away from the collection area 91 along the row direction 94, there are also t columns of sub-pixels 1; t is an integer greater than or equal to 1.

[0093] Referring to Figure 2 As another manner of the embodiment of the present application, the outside of the transition area 92 can have "not belong to" some transition areas 92 sub-pixels 1, i.e. N is less than the total column number of the sub-pixels 1.

[0094] Optionally, all transition driving circuits 122 in any row of transition units 2 in each transition area 92 correspond to all sub-pixels 1 in the same row located in the half area of the collection area 91 close to the transition area 92 along the row direction 94.

[0095] Referring to Figure 4 As a manner of the embodiment of the present application, all transition driving circuits 122 on one side (such as the left side) of the collection area 91 can correspond to the light emitting devices 11 in the sub-pixels 1 on the same half (such as the left half) of the collection area 91, thereby reducing the total length of the connection line 19 and the overlap of the lead lines.

[0096] Optionally, all driving circuits 12 in any row of transition units 2 in each transition area 92 are arranged in a row along the row direction 94.

[0097] Referring to Figure 3 To simplify the structure (such as facilitating the connection of the gate line and the driving circuit 12), all driving circuits 12 (including the local driving circuit 121 and the transition driving circuit 122) in each transition unit 2 in the same row of the same transition area 92 can be arranged in a row.

[0098] It should be understood that, referring to Figure 3 In the conventional display area 93 not belonging to the transition area 92, the driving circuits 12 corresponding to the sub-pixels 1 in the same row can also be arranged in a row.

[0099] Optionally, all light emitting devices 11 in any row of transition units 2 in each transition area 92 are located on the same side of all driving circuits 12 in the row of transition units 2 along the column direction 95.

[0100] Further, referring to Figure 3 When the driving circuits 12 in the same row in the transition area 92 are arranged in a row, the corresponding light emitting devices 11 can also be located on one side of the row of driving circuits 12 and arranged in a row.

[0101] It should be understood that, referring to Figure 3In the regular display area 93, which is not part of the transition area 92, the light-emitting devices 11 corresponding to the sub-pixels 1 in the same row can also be arranged in a row.

[0102] It should be understood that when all the drive circuits 12 in the transition unit 2 are arranged in a row, the relative positions of the transition drive circuits 122 in the row direction 94 are varied.

[0103] For example, you can refer to Figure 3 , Figure 4 In all transition units 2 of the transition zone 92 on one side, the transition drive circuits 122 are in the same relative position.

[0104] For example, you can also refer to Figure 7 In different transition units 2 of the transition region 92 on one side, the transition drive circuit 122 is in different relative positions, for example, in random relative positions.

[0105] As before, if the number of drive circuits 12 (including local drive circuit 121 and transition drive circuit 122) in each transition unit 2 is N / n, then:

[0106] The number of possible relative positions of the transition drive circuit 122 in each transition unit 2 is N / n;

[0107] In a total of m*n transition units 2, the total number of possible combinations of relative positions of the transition drive circuit 122 is: (N / n) m*n .

[0108] Of course, it should be understood that, from the perspective of structural simplification, the relative positions of the transition drive circuits 122 should not be too arbitrary; for example, in each column of transition units 2, the number of relative positions of the transition drive circuits 122 should not exceed 4.

[0109] Optionally, the display substrate 9 further includes multiple row leads, each row lead connecting multiple driving circuits 12 corresponding to multiple sub-pixels 1 in the same row; the row leads connected to the driving circuits 12 corresponding to the sub-pixels 1 in the row where the acquisition area 91 is located include:

[0110] Multiple first row leads 41 extending along the row direction 94, each first row lead 41 is connected to multiple drive circuits 12 in multiple transition units 2 in the same row located on the first side of the acquisition area 91, and is connected to the first drive signal terminal at the end away from the acquisition area 91;

[0111] Multiple second row leads 42 extending along the row direction 94, each second row lead 42 connecting multiple drive circuits 12 in multiple transition units 2 in the same row located on the second side of the acquisition area 91, and connecting a second drive signal terminal at the end away from the acquisition area 91; the first side and the second side are opposite sides along the row direction 94.

[0112] Obviously, each driving circuit 12 needs to obtain certain driving signals through leads in order to work. Among these leads, some correspond to the driving circuits 12 of multiple sub-pixels 1 in the same row, and are called "row leads (such as gate lines, control signal lines, etc.)"; while other leads correspond to the driving circuits 12 of multiple sub-pixels 1 in the same column, and are called "column leads (such as data lines, power signal lines, etc.)".

[0113] In the conventional display area 93, the ports of the same type of driving circuits 12 of a row of sub-pixels 1 can be connected to a row lead; and the ports of the same type of driving circuits 12 of a column of sub-pixels 1 in the conventional display area 93 can also be connected to a column lead, which will not be described in detail here.

[0114] The transition driving circuit 122 corresponding to sub-pixel 1 in the acquisition area 91 is located in the transition areas 92 on both sides of it. To connect these transition driving circuits 122 to the row leads, refer to... Figure 5 Multiple (e.g., all) drive circuits 12 (including local drive circuit 121 and transition drive circuit 122) in the same row in the two transition areas 92 located on both sides of the acquisition area 91 (first side and second side, such as left and right side) can be connected to the first row lead 41 and the second row lead 42 located on both sides of the acquisition area 91, respectively. The above row leads are connected to the corresponding drive signal terminals (first drive signal terminal and second drive signal terminal) on the side away from the acquisition area 91. Thus, these row leads can drive the drive circuits 12 corresponding to all sub-pixels 1 in the row of the acquisition area 91 without passing through the acquisition area 91, which can improve the transmittance of the acquisition area 91.

[0115] Among them, the drive signal terminal refers to the structure used to provide drive signals to the corresponding leads, such as the output terminal of the gate drive circuit (GOA) and the connector (such as the pad) used to connect to the driver IC, etc., which will not be described in detail here.

[0116] It should be understood, with reference Figure 5 In addition to the first row lead 41 and the second row lead 42 mentioned above, for each row (i.e., the row in which all sub-pixels 1 are not in the acquisition area 91) corresponding to the driving circuit 12, a third row lead 43 extending along the row direction 94 can also be used to power it. Both ends of the third row lead 43 can be connected to the corresponding driving signal terminals (or only one end can be connected).

[0117] It should be understood that it is also feasible to set the row leader of the row corresponding to the acquisition area 91 in other ways, such as passing through the acquisition area 91 or "bypassing" the acquisition area 91.

[0118] Optionally, the collection region 91 is located at one end of the display region 99 along the column direction 95.

[0119] Referring to Figure 1 , Figure 2 For the sake of simplifying the structure, the collection region 91 can be located at one end of the display region 99 along the column direction 95, such as at the “top” or “bottom”.

[0120] Optionally, all the transition drive circuits 122 in any column of transition units 2 are arranged in a row along the column direction 95.

[0121] Referring to Figures 4 to 6 In one transition region 92, all the transition drive circuits 122 in one column of transition units 2 can be arranged in a column, or in other words, the transition drive circuits 122 in the same column of transition units 2 are at the same relative position, so that these transition drive circuits 122 are connected to one data line.

[0122] Optionally, the collection region 91 is located at one end of the display region 99 along the column direction 95; the display substrate 9 further comprises a plurality of column leads, each column lead connecting a plurality of drive circuits 12 corresponding to a plurality of sub-pixels 1 in the same column; the column lead connected to the drive circuits 12 corresponding to the sub-pixels 1 in the column where the collection region 91 is located comprises a bent column lead 54: each bent column lead 54 comprises:

[0123] a first longitudinal portion 541 extending along the column direction 95, the first longitudinal portion 541 connecting a plurality of drive circuits 12 corresponding to a plurality of sub-pixels 1 located outside the collection region 91 in the same column;

[0124] a second longitudinal portion 542 extending along the column direction 95, the second longitudinal portion 542 connecting a plurality of transition drive circuits 122 corresponding to a plurality of sub-pixels 1 located in the collection region 91 in the same column;

[0125] a transverse portion 543 connecting the first longitudinal portion 541 and the second longitudinal portion 542.

[0126] The transition drive circuits 122 corresponding to the sub-pixels 1 in the collection region 91 are located in the transition regions 92 on both sides thereof, in order to connect these transition drive circuits 122 to the column leads, as one way of the embodiment of the present application, the bent column lead 54 can be provided. Figure 6

[0127] ​The second longitudinal portion 542 of each of the bent column lead 54 is connected with the transition driving circuit 122 corresponding to the sub-pixel 1 in the transition region 92. Meanwhile, the second longitudinal portion 542 of the bent column lead 54 is connected with the driving circuit 12 of the sub-pixel 1 in the transition region 92. Furthermore, the first longitudinal portion 541 and the second longitudinal portion 542 are connected through the transverse portion 543, so that each portion of the bent column lead 54 obtains the same signal.

[0128] It can be seen that all portions of the bent column lead 54 do not need to enter the collection region 91, so that the transmittance of the collection region 91 can be improved.

[0129] The transverse portion 543 can connect the first longitudinal portion 541 and the second longitudinal portion 542 in the normal display region 93 (for example, near the collection region 91) or in the frame region outside the display region 99, which will not be described in detail herein.

[0130] It should be understood that, referring to Figure 6 The above-mentioned mutually overlapped leads should be arranged in different layers and separated by an insulating layer to avoid mutual conduction, which will not be described in detail herein.

[0131] It should be understood that, referring to Figure 7 If the plurality of transition driving circuits 122 in the transition unit 2 in the transition region 92 are not arranged in a column along the column direction 95, the second longitudinal portion 542 of each of the bent column lead 54 can also have a plurality of second longitudinal portions 542.

[0132] It should be understood that, referring to Figure 6 In addition to the above-mentioned bent column lead 54, for the driving circuit 12 corresponding to the sub-pixel 1 in each column (that is, the column in which all the sub-pixels 1 are not in the collection region 91) (including the driving circuit 12 in the normal display region 93 and the local driving circuit 122 in the transition region 92), a third column lead 53 extending along the column direction 95 can also be used to supply power.

[0133] It can be seen that the total number of each column lead (including the bent column lead 54 and the third column lead 53) in the above-mentioned display substrate 9 is N (assuming that N is the total number of columns of the sub-pixel 1 in the display region 99).

[0134] Optionally, the acquisition area 91 is located at one end of the display area 99 along the column direction 95; the display substrate 9 also includes multiple column leads, each column lead connecting multiple driving circuits 12 corresponding to multiple sub-pixels 1 in the same column; the column leads connected to the driving circuits 12 corresponding to the sub-pixels 1 in the column where the acquisition area 91 is located include:

[0135] Multiple first column leads 51 extending along the column direction 95, each first column lead 51 connecting multiple driving circuits 12 corresponding to multiple sub-pixels 1 located outside the acquisition area 91 in the same column;

[0136] Multiple second column leads 52 extending along the column direction 95, each second column lead 52 connecting multiple transition drive circuits 122 corresponding to multiple sub-pixels 1 located in the acquisition area 91 in the same column.

[0137] As another embodiment of the present invention, it can also be referred to Figure 8 The second column of leads 52 supplies power to the multiple transition driving circuits 122 corresponding to multiple (e.g., all) sub-pixels 1 located in the same column within the acquisition area 91. That is, the second column of leads 52 "only" supplies power to the transition driving circuits 122. The first column of leads 51 supplies power to the multiple driving circuits 12 corresponding to multiple (e.g., all) sub-pixels 1 located outside the acquisition area 91 (located in the conventional display area 93) in the same column. That is, the first column of leads 51 "only" supplies power to the driving circuits 12 outside the acquisition area 91. Thus, these first column of leads 51 do not need to enter the acquisition area 91, which can improve the transmittance of the acquisition area 91.

[0138] It should be understood, with reference Figure 8 In addition to the first column lead 51 and the second column lead 52 mentioned above, for each column (i.e., the column in which all sub-pixels 1 are not in the acquisition area 91) that is unrelated to the acquisition area 91, the corresponding driving circuit 12 (including the driving circuit 12 in the conventional display area 93 and the local driving circuit 122 in the transition area 92) can be powered by a third column lead 53 extending along the column direction 95.

[0139] Therefore, it can be seen that in the above display substrate 9, the total number of each type of column lead (including the first column lead 51, the second column lead 52, and the third column lead 53) is N+n (assuming that N is the total number of columns of sub-pixel 1 in the display area 99).

[0140] Secondly, referring to Figure 9 This invention provides a display device, comprising:

[0141] Any of the above-mentioned display substrates 9;

[0142] An image acquisition unit 8 is provided on the back side of the display substrate 9. The image acquisition unit 8 is used to acquire images through the acquisition area 91 of the display substrate 9.

[0143] The display device of the embodiment of the present application comprises the display substrate 9 and the image acquisition unit 8 (such as a camera) above, the image acquisition unit 8 is arranged at the back side of the display substrate 9 and is at the position corresponding to the acquisition area 91 of the display substrate 9, so that the image of the display side of the display device can be acquired through the acquisition area 91.

[0144] The display device can be a display device using under-screen camera (so the image acquisition unit 8 is invisible at the display side), for example, a full-screen display device (i.e. a display device capable of displaying at all positions of the display side).

[0145] In the display device of the embodiment of the present application, the display substrate 9 can be combined with other substrates (such as a cell substrate) to form a display panel, so that the image acquisition unit 8 is also arranged at the back side of the display panel.

[0146] The display device of the embodiment of the present application can further comprise other structures, such as a driving chip, a power supply component, a support frame, etc., which will not be described in detail here.

[0147] Specifically, the display device of the embodiment of the present application can be any product or component with display function, such as electronic paper, mobile phone, tablet computer, television, display, notebook computer, digital photo frame, navigator, etc.
