The technical solution of the present application is explained below by a plurality of examples. In the following examples, an electronic component is taken as an example of a camera.
Fig. 1 is a schematic view of a display substrate according to a first embodiment of the present disclosure. As shown in fig. 1, the display substrate provided in this embodiment includes: a first display area 10, a second display area 12, and a first non-display area 14; wherein the second display area 12 is located between the first display area 10 and the first non-display area 14. However, this is not limited in this application. For example, the second display area may be located in the middle of the first display area, i.e., the periphery of the second display area is surrounded by the first display area; or the two opposite sides of the second display area are the first display areas.
In the present embodiment, the second display region 12 is located at a lower side of the first display region 10, and the first non-display region 14 is located at a lower side of the second display region 12. The first non-display area 14 may include: a PAD area. The PAD area is a pressure bonding area, and is an area for connecting a signal line of the display area with an external control circuit (e.g., a flexible circuit board (COF)) after a cutting and polishing process.
In this embodiment, the second display area 12 corresponds to a position where the off-screen camera is located. As shown in fig. 1, the projection of the camera onto the display substrate is located in the off-screen camera area 120, and the off-screen camera area 120 is located within the second display region 12. As shown in fig. 1, the area of the second display region 12 is larger than the area of the off-screen camera area 120. However, this is not limited in this application. For example, the area of the second display region may be the same as the area of the off-screen camera area, i.e. the off-screen camera area may completely coincide with the second display region. In this embodiment, the shape of the under-screen camera area 120 may be the same as or different from the shape of the projection of the camera on the display substrate, for example, when the projection of the camera on the display substrate is circular, the under-screen camera area may be a circular area or a rectangular area as long as it is larger than the projection of the camera.
In an exemplary embodiment, the under-screen camera area 120 may be a trace avoiding area (corresponding to the aforementioned first trace avoiding area). In other words, traces that pass through the off-screen camera area 120 may be migrated, for example, traces within the off-screen camera area 120 may be migrated into the second display area 12 outside of the off-screen camera area 120. The routing arrangement mode after migration is not limited in the application.
In an exemplary embodiment, the traces and electrodes in the off-screen camera area 120 may be made of transparent materials, so as to improve the transmittance of the off-screen camera area 120.
As shown in fig. 1, the display substrate provided in this embodiment further includes second non-display regions 11, where the second non-display regions 11 are located at two opposite sides of the first display region 10 and adjacent to the first non-display region 14. The second non-display region 11 is an edge wiring region on both left and right sides of the first display region 10.
In this embodiment, a plurality of light emitting units are arranged on the display substrate, and each light emitting unit includes a light emitting structure and a pixel driving circuit, and one pixel driving circuit is used for driving one light emitting structure to operate. A plurality of light emitting units (sub-pixels) may form one pixel. For example, one pixel may include three light emitting units (e.g., a red sub-pixel, a green sub-pixel, and a blue sub-pixel). In one example, the light emitting structure may include an anode, a hole transport layer, a light emitting function layer, an electron transport layer, and a cathode, which are sequentially stacked; each pixel driving circuit may include a plurality of thin film transistors and capacitors, and the individual sub-pixels individually control light emitting display by their corresponding pixel driving circuits.
In this embodiment, any one of the pixel driving circuits may be electrically connected to the scanning line driving circuit through a scanning signal line and electrically connected to the data line driving circuit through a data signal line. The scan line driving circuit may supply a scan signal to the pixel driving circuit through the scan signal line, and the data line driving circuit may supply a data signal to the pixel driving circuit through the data signal line. However, this is not limited in this application. In other implementations, the scan line driver circuit may supply a scan signal, a reset signal, and the like to the pixel driver circuit.
Fig. 2 is a circuit layout example of a display substrate according to a first embodiment of the present application. Fig. 3 is a circuit arrangement example diagram of the first non-display region in fig. 2. As shown in fig. 2, in the present example, a plurality of light emitting units 20 are regularly arranged within the first display region 10, wherein the light emitting units 20 include a first light emitting structure and a first pixel driving circuit for driving the first light emitting structure to operate.

As shown in fig. 2, a plurality of second light emitting structures 220 are regularly arranged within the second display region 12. A second light emitting structure 220 is driven by a second pixel driving circuit to emit light. The second pixel driving circuit for driving the second light emitting structure 220 to operate is located in the first non-display region 14. The plurality of second light emitting structures 220 in the second display region 12 are arranged in n-k rows × m columns in a matrix.
As shown in fig. 2, in the second display region 12, m columns of data signal lines 212 and connecting traces 213 for electrically connecting the second light emitting structure 220 and the second pixel driving circuit are disposed along the column direction (i.e., Y direction). In this example, the first light emitting structures in the first display region 10 and the second light emitting structures in the second display region 12 have the same number of columns, and there are no first light emitting structures and no second light emitting structures arranged in the same row. In this way, the scanning signal lines may not be disposed in the second display region 12, and the scanning signal lines and the second pixel driving circuit may be disposed in the first non-display region together, so as to simplify the wiring in the second display region 12 and improve the transmittance of the second display region.
In order to facilitate distinction of rows (Row) of the scanning signal line, the light-emitting structure, and the pixel driving circuit, the rows may be referred to as a 1 st Row, a 2 nd Row, … …, a k-1 st Row, … …, and an nth Row in order from the top in fig. 2, and similarly, in order to facilitate distinction of columns (columns) of the data signal line, the light-emitting structure, and the pixel driving circuit, the columns may be referred to as a 1 st Column, a 2 nd Column, … …, an h th Column, … …, and an m th Column in order from the left in fig. 2.
As shown in fig. 2, the second non-display region 11 located on both left and right sides of the first display region 10 is provided therein with a scanning line driving circuit 21 for supplying a scanning signal to the first pixel driving circuit in the first display region 10. The scanning signal lines 211 in the first display region 10 extend in the X direction and electrically connect the first pixel driving circuit and the scanning line driving circuit 21. The first pixel driving circuits disposed in the same row in the first display region 10 are electrically connected to the same scanning signal line 211.
As shown in fig. 2, a data line driving circuit for supplying a data signal to the first pixel driving circuit in the first display region 10 is located in the first non-display region 14. The data signal lines 212 in the first display region 10 extend in the Y direction and electrically connect the first pixel driving circuit and the data line driving circuit. The first pixel driving circuits disposed in the same column in the first display region 10 are electrically connected to the same data signal line 212.
As shown in fig. 3, the control unit 24 located at the first non-display area 14 includes: a plurality of second pixel driving circuits 221 regularly arranged, a scanning line driving circuit 242 for supplying a scanning signal to the second pixel driving circuits 221, a data line driving circuit 241, and a control circuit (not shown). The control circuit is electrically connected to the data line driving circuit 241 and the scanning line driving circuits 242 and 21, respectively. The control circuit is configured to supply control signals to the scanning line driving circuits 21 and 242 and the data line driving circuit 241 to control the operations of the scanning line driving circuits 21 and 242 and the data line driving circuit 241. In addition, the control circuit may supply gradation data specifying a gradation (luminance) to be displayed in each pixel driving circuit to the data line driving circuit 241.
As shown in fig. 3, in the first non-display area 14, n-k rows of scanning signal lines 211 are provided in a row direction (i.e., X direction), and m columns of data signal lines 212 are provided in a column direction (i.e., Y direction). The data signal lines 212 and the scan signal lines 211 are electrically insulated from each other. The second pixel driving circuits 221 in the first non-display region 14 are arranged so as to correspond to intersections of the scanning signal lines 211 in the k-1 row and the data signal lines 212 in the m columns, respectively, that is, the second pixel driving circuits in the first non-display region 14 are arranged in a matrix of n-k rows × m columns. The second pixel driving circuits 221 disposed in the first non-display region 14 are electrically connected to the second light emitting structures 220 in the second display region 12 in a one-to-one correspondence manner through the connecting wires 213. In this description, the second light emitting structures 220 in the second display region 12 and the second pixel driving circuits 221 in the first non-display region 14 are both a matrix array of n-k rows × m columns, and the driving signal provided by the second pixel driving circuit 221 in the ith row and the jth column to the second light emitting structure 220 in the ith row and the jth column is denoted as D (i _ j).
As shown in fig. 3, the second pixel driving circuit 221 for driving the second light emitting structure 220 to operate is electrically connected to the scanning line driving circuit 242 through the scanning signal line 211 and electrically connected to the data line driving circuit 241 through the data signal line 212. The scanning signal lines 211 in the first non-display region 14 extend in the X direction and are electrically connected to the scanning driving circuit 242. The second pixel driving circuits 221 disposed in the same row in the first non-display region 14 are electrically connected to the same scanning signal line 211.
As shown in fig. 2 and 3, the data signal lines 212 in the first display region 10 and the first non-display region 14 extend in the Y direction and are electrically connected to the data line driving circuit 241. The pixel driving circuits disposed in the same column in the first display region 10 and the first non-display region 14 are electrically connected to the same data signal line 212. The data signal line 211 may simultaneously supply data signals to the first pixel driving circuit located in the first display region 10 and the second pixel driving circuit located in the first non-display region 14 on the column. The circuit arrangement provided by this example can achieve the same circuit control and picture display effects as when the second pixel driving circuit is located in the second display region without adding or changing other circuit structures.
In this embodiment, the scanning line driving circuits 21 and 242 may be used to sequentially select the 1 st to n th rows in each frame. For example, the scan line driver circuit 21 may supply the scan signals PS (1), PS (2), and … … PS (k-1) to the circuits of the scan signal lines of the 1 st, 2 nd, … … th, and k-1 th rows, respectively, and the scan line driver circuit 242 may supply the scan signals PS (k), PS (k +1), and … … PS (n) to the circuits of the scan signal lines of the k th, k +1, … … th, and n th rows, respectively. In this description, a frame is a period necessary for displaying an image corresponding to 1 shot (screen) on a display device, and a vertical scanning frequency is 60Hz, and a period corresponding to 16.67 milliseconds corresponding to 1 cycle of the vertical scanning frequency.
In this embodiment, the data line driver circuit 241 may supply a data signal of a potential corresponding to the gradation data of the pixel driver circuit to the pixel driver circuits in the row selected by the scan line driver circuit via the data signal line. In this description, for convenience, data signals supplied to the data signal lines of the 1 st, 2 nd, … … th, and m th columns are referred to as DS (1), DS (2), … …, and DS (m), respectively.
In this embodiment, since the pixel driving circuit is not disposed in the second display region, the transmittance of the second display region can be improved, so that the imaging quality of the camera positioned under the second display region is improved. Moreover, the second light-emitting structure in the second display area is connected with the second pixel driving circuit in the first non-display area through the connecting wires, so that the second display area can have the same display effect as the first display area.
