Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Display devices with cameras are widely used in mobile phones, computers, and other devices. Fig. 1 is a diagram illustrating a display device having a camera according to a related art. As can be seen from fig. 1, the area of the peripheral region where the camera is located is large, so that the increase of the area of the display region of the display device is limited, that is, the increase of the proportion of the display region on the display side is limited, and therefore, the embodiment of the present invention provides another arrangement manner of the camera.
Fig. 2 is a schematic structural diagram of a first display device according to an embodiment of the present invention, and as shown in fig. 2, the display device 0 may include: camera 01, display panel 02 and control circuitry (not shown in fig. 2). A mounting hole (not shown in fig. 2) penetrating through the display panel 02 is provided in the display area a of the display panel 02, and the camera 01 is located in the mounting hole. The plurality of gate lines (not shown in fig. 2) and the plurality of data lines (not shown in fig. 2) in the display panel include: the control circuit is electrically connected with each line segment obtained by division and used for inputting signals to each line segment.
In summary, in the display device provided in the embodiments of the present invention, the camera is disposed in the display area of the display panel, and the control circuit can input a signal to each line segment divided by the mounting hole in the display panel, so that the portion of the display panel except for the mounting hole can normally display an image. Therefore, it is not necessary to provide a camera in the peripheral region of the display device, and the area of the peripheral region can be appropriately reduced to increase the occupation ratio of the display region on the display side. In addition, the camera is arranged in the display area of the display panel, so that the arrangement mode of the camera is enriched.
It should be noted that the camera located in the mounting hole may be used to collect an image on the display side of the display panel, and at this time, the camera may function as a front camera. Optionally, the camera may also be used to collect an image of the non-display side of the display panel, and the camera may play a role of a rear camera at this time, which is not limited in the embodiment of the present invention.
Alternatively, the display area a may include: a central area, and an edge area surrounding the central area, where the mounting hole may be located. Therefore, when the camera in the mounting hole is used for shooting or taking pictures, the mounting hole does not influence the normal display of the image in the central area, and meanwhile, the convenience of operation of a user is improved.
Fig. 3 is a schematic structural diagram of a second display device according to an embodiment of the present invention, as shown in fig. 3, based on fig. 2, a display panel (not shown in fig. 3) may include: a substrate 021, and a plurality of gate lines (e.g., gate line G1, gate line G2, etc.) and a plurality of data lines (e.g., data line D1, data line D2, etc.) disposed on the substrate 021, for example, in fig. 3, x gate lines and y data lines are included in the display panel.
Optionally, the plurality of gate lines are parallel to each other, the plurality of data lines are parallel to each other, and each of the plurality of gate lines and the plurality of data lines passing through the mounting hole B is divided into two line segments by the mounting hole B, that is, each of the plurality of gate lines and the plurality of data lines includes a line passing through the mounting hole. Illustratively, as shown in fig. 3, the gate line G2, the data line D2, and the data line G3 all pass through the mounting hole B, and the mounting hole B divides the gate line G2 into a segment G21 and a segment G22, the mounting hole B divides the data line D2 into a segment D21 and a segment D22, and the mounting hole B divides the data line D3 into a segment D31 and a segment D32. The control circuit may be electrically connected to each of the line segments (e.g., line segment G21, line segment G22, line segment D21, line segment D22, line segment D31, and line segment D32) obtained by the division. The control circuit may be configured to input a signal to each of the line segments in the gate line passing through the mounting hole and to input a signal to each of the line segments in the data line passing through the mounting hole.
Alternatively, the control circuit may be electrically connected to lines (e.g., the gate line G1, the gate line G3, the data line D1, etc. in fig. 3) of the plurality of gate lines and the plurality of data lines that do not pass through the mounting holes. The control circuit may sequentially turn on a plurality of gate lines and input a signal to a portion of each data line crossing the gate line when each gate line is turned on. When the control circuit conducts the grid line which does not pass through the mounting hole, the control circuit can be realized by directly inputting a signal to the grid line; when the control circuit conducts the grid line passing through the mounting hole, the control circuit can be realized by inputting signals to each line segment obtained by dividing the grid line by the mounting hole. When each gate line is turned on, the control circuit may directly input a signal to a data line that does not pass through the mounting hole, and may input a signal to a line segment that crosses the gate line among a plurality of line segments divided by the mounting hole in the data line. In this way, even if the data lines or the gate lines are divided by the mounting holes B, the control circuit can still control the pixels (not shown in fig. 3) at the crossing positions of the gate lines and the data lines in the display panel through the gate lines and the data lines.
For example, when the control circuit turns on the gate line G1, since the gate line G1 does not pass through the mounting hole B, the control circuit may input a signal directly to the gate line G1; when the gate line G2 is turned on, the gate line G2 passes through the mounting hole B and is divided into a segment G21 and a segment G22 by the mounting hole B, and therefore the control circuit needs to input signals to both the segment G21 and the segment G22. When the gate line G1 is turned on, since the data line D1 does not pass through the mounting hole B, the data line D2 passes through the mounting hole B, and is divided into the segment D21 and the segment D22 by the mounting hole B, the control circuit can directly input a signal to the data line D1 to control the pixel at the intersection of the gate line G1 and the data line D1, and also needs to output a signal to the segment D21, which intersects the gate line G1, of the segment D21 and the segment D22 to control the pixel at the intersection of the gate line G1 and the data line D2.
Optionally, fig. 4 is a schematic structural diagram of a third display device provided in the embodiment of the present invention, as shown in fig. 4, on the basis of fig. 3, the display device 0 may further include: the auxiliary circuit 03 and the display panel may further include: n of the first switches 022, n ≧ 1, and n ═ 2 is exemplified in fig. 4. The plurality of data lines include n data lines passing through the mounting hole B, and each of the n data lines is divided into a first line segment L1 and a second line segment L2 by the mounting hole B (it should be noted that the line segments D21 and D31 in fig. 3 are equivalent to the first line segment, and the line segments D22 and D32 in fig. 3 are equivalent to the second line segment).
With continued reference to fig. 4, the n data lines may be divided into n first line segments L1 and n second line segments L2 by the mounting holes B. The n first line segments L1 in the display device 0 correspond to the n first switches 022 one-to-one, each first line segment L1 is connected to one target data line that does not pass through the mounting hole B through its corresponding first switch 022, and the target data lines connected by any two first line segments L1 are different. As shown in fig. 4, the first line segment L1 in the data line D2 is connected to the data line D1 through a first switch 022, and the first line segment L1 in the data line D3 is connected to the data line D4 through another first switch 022.
Optionally, the n target data lines connected by the n data lines may be: and the data lines are arranged on the part of the plurality of data lines close to the n data lines. In this case, the wire required to electrically connect the first line segment and the target data line is short, and the waste of material is small. Or, the n target data lines connected by the n data lines may also be: the data lines of the plurality of data lines are away from the n data lines, which is not limited in the embodiment of the present invention.
The control circuit is connected with the second line segment L2, each of the gate lines passing through the mounting hole B, and the target data line, and since the first line segment L1 is connected with the target data line, the control circuit can be electrically connected to the first line segment L1 through the target data line. The auxiliary circuit 03 is electrically connected to the n first switches 022, and the auxiliary circuit 03 may be configured to: when the gate line crossing the n first segments L1 is turned on, any one of the first switches 022 is controlled to be turned on after turned off. The control circuit is used for inputting signals to the first line segment connected with each target data line through the target data line when the first switch connected with the target data line is closed. The control circuit may be further configured to input a signal to the target data line when the first switch 002 is turned on, and the signal transmitted on the target data line can only be stored in the target data line and cannot be transmitted to the first segment L1. Thus, the purpose that the control circuit respectively inputs signals to the target data line and the first line segment connected with the target data line can be achieved. The control circuit may further input a signal to each of the n second segments when the gate line crossing the n second segments is turned on.
It should be noted that there may be multiple realizations of the control circuit in the embodiment of the present invention, and one of the realizations will be taken as an example for the embodiment of the present invention. For example, fig. 5 is a schematic structural diagram of a fourth display device according to an embodiment of the present invention, and as shown in fig. 5, on the basis of the display device shown in fig. 4, the control circuit 04 may include: a grid line control unit (not shown in fig. 5), km second switches 041, k switch control units 042, and m signal sources 043, where k is greater than or equal to 2 (fig. 5 takes k as an example equal to 3), and m is greater than or equal to 1. For example, the switch control unit 042 may include a Multiplexer (MUX).
The grid line control unit is electrically connected to the grid lines which do not pass through the mounting holes and each line segment obtained by dividing the plurality of grid lines, and the grid line control unit can be used for sequentially conducting the plurality of grid lines.
The display panel may include pixels of k colors (e.g., red, green, and blue pixels, respectively, when k is 3). The second line segment L2 in the display panel and the data line that does not pass through the mounting hole B may be both referred to as a connection line, that is, the connection line may include: the second line segment L2 or the data line that does not pass through the mounting hole B. The display panel may include k sets of connecting lines, each set of connecting lines including m connecting lines, the m sets of connecting lines including km connecting lines. The km connecting lines may be connected to the km second switches 041 one by one. Each set of connection lines may be electrically connected to a pixel of one color, and each switch control unit 043 is electrically connected to the second switch 041 connected to one set of connection lines. Each signal source 043 is connected to one of the connection lines in each group (i.e., each signal source 043 is connected to k connection lines in common), and the connection lines to which any two signal sources 043 are connected are different. m signal sources 043 may be used to output signals when each gate line is turned on; the k switch control units 042 may be configured to control the second switch 041 electrically connected to the switch control unit to be closed at different stages when each gate line is turned on, so as to input the signals output by the m signal sources 044 to different connection lines at different stages.
For example, fig. 6 is a timing chart provided by an embodiment of the present invention, and the timing chart can be used in the display device 0 shown in fig. 5. Referring to fig. 5 and 6, the gate line control unit may control a plurality of gate lines to be sequentially turned on, and a period of time for which each gate line is turned on may include three stages, for example, a period of time for which the gate line G1 is turned on in fig. 6 may be divided into a first stage J1, a second stage J2 and a third stage J3.
In the first phase J1, the first switch control unit 0421 outputs a high level, and the second switch control unit 0422 and the third switch control unit 0423 both output a low level, at which time the second switch 041 electrically connected to the first switch control unit 0421 is closed and the second switch 041 electrically connected to the second switch control unit 0422 and the third switch control unit 0423 is opened. The signals from the m signal sources 044 can be input to the first set of connection lines in the first phase J1, while no signal is input to either the second set of connection lines or the third set of connection lines.
In the second phase J2, the second switch control unit 0422 outputs a high level, and the first switch control unit 0421 and the third switch control unit 0423 both output a low level, at which time the second switch 041 electrically connected to the second switch control unit 0422 is closed and the second switch 041 electrically connected to the first switch control unit 0421 and the third switch control unit 0423 is opened. The signals from the m signal sources 044 can be input into the second set of connection lines in the second stage J2, while no signal is input into either the first set of connection lines or the third set of connection lines.
In the third phase J3, the third switch control unit 0423 outputs a high level, and the first switch control unit 0421 and the second switch control unit 0422 both output a low level, at which time the second switch 041 electrically connected to the third switch control unit 0423 is closed and the second switch 041 electrically connected to the first switch control unit 0421 and the second switch control unit 0422 is opened. The signals from the m signal sources 044 can be input into the third set of connection lines in the third stage J3, while no signal is input into either the first set of connection lines or the second set of connection lines.
Thus, under the control of the three switch control units, the signals output by the m signal sources are respectively input to different groups of connection lines in different stages (the first stage J1, the second stage J2 and the third stage J3). It should be noted that, in the embodiment of the present invention, the switch is closed under the action of the high level and opened under the action of the low level, alternatively, the switch is closed under the action of the low level and opened under the action of the high level, which is not limited in the embodiment of the present invention.
Further, each of the first, second, and third stages J1, J2, J3 may in turn include: a closing phase P1 and an opening phase P2 arranged in succession. The embodiment of the present invention exemplifies the closing phase P1 and the opening phase P2 in each of the first phase J1, the second phase J2 and the third phase J3, taking the closing phase P1 and the opening phase P2 in the first phase J1 as an example.
Illustratively, during the closing phase P1 of the first phase J1, the auxiliary circuit 03 outputs a high level to control the first switch 022 to close. At this time, if a signal from the signal source is transmitted to the target data line T, the signal transmitted to the target data line T can be input to the first line segment L1 connected to the target data line T through the first switch.
During the on phase P2 of the first phase J1, the auxiliary circuit 03 outputs a low level to control the first switch 022 to be turned on. At this time, if a signal from the signal source is transmitted on the target data line T, the signal cannot be input to the first line segment L1 connected to the target data line T through the first switch, and the signal transmitted on the target data line T can be stored only in the target data line T.
That is, for a signal source connected to a target data line, in a closing phase, a second switch between the signal source and the target data line connected to the signal source is closed, a first switch between the target data line and a first line segment connected to the target data line is closed, the signal source, the target data line and the first line segment are conducted, and at this time, a signal output by the signal source can be input to the first line segment through the target data line. In the starting stage, the second switch between the signal source and the target data line connected with the signal source is closed, the first switch between the target data line and the first line segment connected with the target data line is opened, the signal source is conducted with the target data line, and the target data line is disconnected with the first line segment. That is, the signal source may output a signal that needs to be input to the first line segment in the close phase, and output a signal that needs to be input to the target data line in the open phase.
It should be noted that, in the embodiment of the present invention, the signal source outputs different signals in the closed phase and the open phase as an example, optionally, the signals output by the signal source in the open phase and the closed phase may also be the same, and the embodiment of the present invention does not limit this.
It should be noted that in fig. 6, during the time period when each gate line is turned on, the plurality of switch control units may start to operate sequentially immediately after the gate line is turned on. When each switch control unit works, the switch control unit needs to conduct the second switch connected with the switch control unit, and after the previous switch control unit in the switch control units stops working, the next switch control unit works immediately. During the time period in which each switch control unit is operated, the auxiliary circuit may be operated immediately after the switch control unit starts operating. When the auxiliary circuit works, the first switch which needs to be controlled to be electrically connected with the auxiliary circuit is firstly switched on, and then the first switch is controlled to be switched off until the switch control unit stops working. In a time period when the first switch is turned on, the signal source connected to the target data line may immediately output a signal that needs to be input to the first line segment to which the target data line is connected after the first switch is turned on, and in a time period when the first switch is turned off, the signal source may also immediately output a signal that needs to be input to the target data line.
Optionally, as shown in fig. 7, in the time period when each gate line is turned on, the plurality of switch control units may further start to operate sequentially after a time delay after the gate line is turned on, and after the previous switch control unit stops operating, the next switch control unit may start to operate after a time delay. During the time period in which each switch control unit is operated, the auxiliary circuit may be started after a delay after the switch control unit is started to operate. In a time period in which the first switch is turned on, the signal source connected to the target data line may delay a period of time to output the signal that needs to be input to the first line segment connected to the target data line after the first switch is turned on, and in a time period in which the first switch is turned off, the signal source may delay a period of time to output the signal that needs to be input to the target data line.
Optionally, fig. 8 is a schematic structural diagram of a fifth display device according to an embodiment of the present invention, as shown in fig. 8, on the basis of fig. 2, the display panel may include: a substrate 021, and a plurality of gate lines (e.g., gate line G1 to gate line Gx) and a plurality of data lines (e.g., data line D1 to data line Dy) disposed on the substrate 021.
The plurality of gate lines are parallel to each other, and each of the plurality of gate lines (e.g., gate line G3 and gate line G4) passing through the mounting hole B is divided into two line segments (not shown in fig. 8) by the mounting hole B, that is, the plurality of gate lines include lines divided by the mounting hole. The plurality of data lines may include: at least one first data line (e.g., data lines D5 through D14 in fig. 8) near the mounting hole B, and a plurality of second data lines (e.g., data lines other than the data lines D5 through D14 in fig. 8, e.g., data lines D1, D2, D16, D17, etc.) far from the mounting hole B and parallel to each other. A portion of the first data line near the mounting hole B bypasses the mounting hole B from the periphery of the mounting hole B, and a portion of the first data line far from the mounting hole B may be parallel to the second data line. That is, the data line near the mounting hole B among the plurality of data lines bypasses the mounting hole B from the periphery of the mounting hole.

As shown in fig. 10, the control method of the display apparatus may include:
In summary, in the display device controlled by the control method provided by the embodiment of the invention, the camera is disposed in the display area of the display panel, and the control circuit can input a signal to each line segment divided by the mounting hole in the display panel, so that the portion of the display panel except for the mounting hole can normally display an image. Therefore, it is not necessary to provide a camera in the peripheral region of the display device, and the area of the peripheral region can be appropriately reduced to increase the occupation ratio of the display region on the display side. In addition, the camera is arranged in the display area of the display panel, so that the arrangement mode of the camera is enriched.
It should be noted that, since the mounting hole penetrates through the display panel, the mounting hole may divide at least one gate line and/or at least one data line in the display panel. When the plurality of gate lines and the plurality of data lines each include a line passing through the mounting hole, step 101 may include: the control circuit inputs signals to each line segment in the grid line passing through the mounting hole; and a control circuit inputting a signal to each line segment in the data line passing through the mounting hole.
Furthermore, a plurality of gate lines on the display panel need to be sequentially turned on, and when each gate line is turned on, signals need to be input to the portions of the plurality of data lines, which intersect with the gate line. Illustratively, conducting the gate line through the mounting hole may be achieved by a control circuit. Optionally, the control circuit may be electrically connected to a gate line that does not pass through the mounting hole, and the gate line may be turned on by the control circuit. Further, for example, when a certain gate line is turned on, if a data line crossing the gate line passes through the mounting hole, inputting a signal to a portion of the data line crossing the gate line may be performed by the control circuit. Optionally, the control circuit may be electrically connected to each data line that does not pass through the mounting hole, and when a certain gate line is turned on, inputting a signal to a portion of the data line that crosses the gate line may also be implemented by the control circuit.
As shown in fig. 3, 8 and 9, the control circuit may be connected to each of the undivided lines in the display panel to realize electrical connection to each of the undivided lines. The control circuit may also be connected to each of the segmented lines to make electrical connection to each of the segmented lines. When the control circuit conducts the grid line which does not pass through the mounting hole, the control circuit can be realized by directly inputting a signal to the grid line; when the control circuit conducts the grid line passing through the mounting hole, the control circuit can be realized by inputting signals to each line segment obtained by dividing the grid line by the mounting hole. When each grid line is conducted, the control circuit can be realized by directly inputting signals to the data lines when inputting signals to the data lines which do not pass through the mounting holes; the control circuit may input a signal to a line segment crossing the gate line among line segments obtained by dividing the data line by the mounting hole when inputting a signal to the data line passing through the mounting hole.
As another example, as shown in fig. 4, two line segments obtained by dividing each data line in fig. 3 may be respectively referred to as a first line segment and a second line segment, wherein each first line segment is connected to one target data line through one first switch, and the auxiliary circuit is connected to each first switch. The control circuit may be connected to the second line segment, each of the gate lines passing through the mounting hole, and the target data line, and optionally, may be electrically connected to each of the display panels not passing through the mounting hole. The control circuit can be electrically connected to the first line segment through the target data line and the first switch.
Optionally, the control method of the display device may further include: when the auxiliary circuit is conducted with the grid lines crossed with the n first line sections, each first switch is controlled to be closed first and then opened. The control circuit inputs a signal to each line segment in the data line passing through the mounting hole, and may include: when the first switch connected with each target data line is closed, the control circuit can input signals to the first line section connected with the target data line through each target data line; the control circuit may input a signal to each of the n second segments when the gate line crossing the n second segments is turned on. Optionally, the control method of the display device may further include: the control circuit may input a signal to each target data line when the first switch connected to the target data line is turned on.
Furthermore, the control circuit in the embodiment of the present invention may have a plurality of realizable manners, and one of the realizable manners will be taken as an example for the embodiment of the present invention. For example, as shown in fig. 5, when any one of the gate lines is turned on and signals are input to a portion of the plurality of data lines that intersects the gate line, the k switch control units in the control circuit may control the second switches electrically connected to the switch control units to be closed at different stages when the gate line is turned on, so as to input signals output by the m signal sources to different connection lines (the connection lines are target data lines or second line segments) at different stages. When a signal is input to a connection line connected to the first switch, the auxiliary circuit can input the signal to the connection line or a first line segment connected to the connection line by opening and closing the first switch. For a specific control manner of the control circuit, reference may be made to the above explanation of the timing diagram shown in fig. 6 or fig. 7, and details of the embodiment of the present invention are not repeated herein.
In summary, in the display device controlled by the control method provided by the embodiment of the invention, the camera is disposed in the display area of the display panel, and the control circuit can input a signal to each line segment divided by the mounting hole in the display panel, so that the portion of the display panel except for the mounting hole can normally display an image. Therefore, it is not necessary to provide a camera in the peripheral region of the display device, and the area of the peripheral region can be appropriately reduced to increase the occupation ratio of the display region on the display side. In addition, the camera is arranged in the display area of the display panel, so that the arrangement mode of the camera is enriched.
