The specification may use the word "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments as per the application.
Fig. 1 is a schematic top view of a display screen of a display device according to an embodiment of the present application, and fig. 2 is a side sectional view of the display screen of fig. 1, and as shown in fig. 1 and 2, the embodiment of the present application provides a display device, including a display screen 100, where the display screen 100 includes a first display area 101 and a second display area 102, and the first display area 101 is used to transmit light when a camera works;
the display parameters of the first display area 101 and the display parameters of the second display area 102 are different, so that the display effects of the first display area 101 and the second display area 102 in the first state are the same.
The first display area 101 is not only used for transmitting light when the camera is in operation, but also can be used for normal display when the camera is not in operation. Namely, the first display area 101 can simultaneously meet the effects of light transmission and display, and when the camera is not started, the display screen 100 works normally, and the screen of the first display area 101 is displayed normally as the screen of other areas; when the camera is started, the first display area 101 has better light transmittance, so that light can penetrate through the first display area 101 and enter the camera below the first display area 101, and the image acquisition effect and quality are ensured.
In this embodiment, the first display area 101 has a first state and a second state, where the first state is a state that the first display area 101 and the second display area 102 jointly display, and the second state is a state that the first display area 101 cooperates with the camera to perform shooting, and the first state and the second state can be switched mutually.
In the first state, the display effects of the first display area 101 and the second display area 102 need to be the same, for example, the display brightness is the same, or there is no color difference between the first display area 101 and the second display area 102 to ensure the display effect of the display screen 100. Accordingly, the first display area 101 and the second display area 102 can achieve the same display effect by adjusting the display parameters of the first display area 101 and the second display area 102, respectively.
In this embodiment, by adjusting the voltage of the cathode applied to the first display area 101 and the voltage of the cathode applied to the second display area 102, respectively, different voltages can be provided to the cathodes of the two display areas separately, so that the two display areas achieve the same display effect. For example, when the voltage of the cathode required for the first display area 101 is high, the high voltage may be separately provided for the first display area 101 without adjusting the voltage of the second display area 102, and the overall power consumption of the display device at the time of voltage adjustment may be reduced.
Along a direction perpendicular to the display panel 100 (a normal direction of the display panel 100), the display panel 100 may include a pixel layer 10 (a light emitting layer) and an anode and a cathode provided on both side surfaces of the pixel layer 10, respectively. In operation of the display 100, positive and negative supply voltages are applied to the anode and cathode, respectively, so that holes and electrons move from the anode having a positive voltage and from the cathode having a negative voltage to the pixel layer 10, respectively. The holes and electrons recombine in the pixel layer to generate excitons that transition from an excited state to a ground state to radiate energy, causing the pixel layer 10 to emit light of the corresponding color. The positive anode voltage ELVDD is transmitted to the anode of the pixel layer 10 through the power signal line, and the negative cathode voltage ELVSS is transmitted to the cathode of the pixel layer 10 through the power signal line, and an electric field may be formed between the anode and the cathode, thereby commonly driving the pixel layer 10 to emit light.
The display 100 may be a display employing self-luminous technology, for example. For example, the display 100 may be an Organic Light-Emitting Diode (OLED) display, and an Organic Light-Emitting layer in the OLED display may be used as the pixel layer 10.
According to the display device provided by the embodiment of the invention, the display parameters of the first display area 101 and the second display area 102 can be respectively adjusted, so that the first display area 101 and the second display area 102 achieve the same display effect in the first state, the processing burden of the display device can not be increased, and the overall power consumption of the display device can be reduced.
In this embodiment, the second display area 102 at least partially surrounds the first display area 101, that is, the first display area 101 and the second display area 102 may be joined in a seamless manner, so after the display parameters of different display areas are adjusted to make the display of different display areas match to achieve the same display effect, no interruption or discontinuity of display occurs visually, thereby achieving a better overall screen display effect.
Fig. 1 is a schematic diagram of a structure of the display screen 100 in which the second display region 102 entirely surrounds the first display region 101. In fact, fig. 3 is a schematic top view of another display screen provided in the embodiment of the present application, as shown in fig. 3, the first display area 101 may be further moved in a direction approaching to an edge of the display screen 100, so that a part of the edge of the first display area 101 contacts with a part of the edge of the display screen 100, and a structure in which the second display area 102 partially surrounds the first display area 101 as shown in fig. 3 is formed. The structure of the display 100 will be described below with the second display area 102 entirely surrounding the first display area 101, unless otherwise specified. The second display area 102 partially surrounds the first display area 101 in a similar manner, and will not be described herein.
It will be appreciated that in the second state, the display parameters of the first display area 101 and the display parameters of the second display area 102 may be the same or different. For example, in the second state, neither the first display region 101 nor the second display region may be displayed, and at this time, the display parameters of the first display region 101 and the display parameters of the second display region 102 are the same, and the display effects are also the same. In the second state, the first display area 101 may not be displayed, and the second display area 102 may be displayed normally, that is, the display screen 100 may take a photograph with the first display area 101 while displaying, and at this time, the display parameters of the first display area are different, and the display effect is also different. In other embodiments, in the second state, the first display area 101 may be displayed with a lower brightness so that light passes through, the second display area 102 may be displayed with a higher brightness, and the display effects of the first display area 101 and the second display area 102 are different, where the display parameters of the first display area 101 and the second display area 102, such as the voltage provided to the cathode of the first display area 101 and the voltage provided to the cathode of the second display area 102, may be the same.
Further, the display 100 further includes:
a first cathode 1011, the first cathode 1011 providing a voltage to the first display area 101;
a second cathode 1021, the second cathode 1021 providing a voltage for the second display area 102;
the voltage value of the first cathode 1011 corresponding to the first display area 101 is different from the voltage value of the second cathode 1021 corresponding to the second display area 102.
By respectively arranging the first cathode 1011 and the second cathode 1021 which are electrically connected with the first display area 101 and the second display area 102, the different display areas can obtain corresponding cathode voltages according to the display effects thereof, the cathode voltages of the display screen 100 do not need to be adjusted integrally, and the overall power consumption of the display screen 100 is reduced while the display effects of the display screen 100 are ensured.
In some embodiments, when the first display area 101 and the second display area 102 are both in the first state, the voltage value of the first cathode 1011 corresponding to the first display area 101 is greater than the voltage value of the second cathode 1021 corresponding to the second display area 102;
the first state is a state in which the first display area 101 and the second display area 102 are displayed together.
Since the first display area 101 needs to transmit light, the pixel distribution density of the first display area 101 is smaller than that of the second display area 102, that is, the brightness of the first display area 101 is smaller than that of the second display area 102 at the same voltage. When the first display area 101 and the second display area 102 are both in the first state, the voltage value of the first cathode 1011 corresponding to the first display area 101 is greater than the voltage value of the second cathode 1021 corresponding to the second display area 102, so that the display of the first display area 101 and the display of the second display area 102 are mutually matched, the same display effect is achieved, and the display screen 100 looks more natural.
As shown in fig. 1 and 2, the display device further includes:
a first driving circuit 201 electrically connected to the first cathode 1011 for providing a first cathode voltage to the first cathode 1011 corresponding to the first display area 101;
the second driving circuit 202 is electrically connected to the second cathode 1021, and provides a second cathode voltage for the second cathode 1021 corresponding to the second display area 102.
The first driving circuit 201 and the second driving circuit 202 are respectively connected to the driving chip 200, the driving chip 200 provides a first cathode voltage to the first cathode 1011 through the first driving circuit 201, and the driving chip 200 provides a second cathode voltage to the second cathode 1021 through the second driving circuit 202.
The first cathode voltage of the first cathode 1011 (the first display area 101) and the second cathode voltage of the second cathode 1021 (the second display area 102) are respectively adjusted by different driving circuits, so that the display of the first display area 101 is matched with the display of the second display area 102, the same display effect is achieved, the cathode voltage of the display screen 100 is not required to be integrally adjusted, and the overall power consumption of the display screen 100 can be effectively reduced. In addition, since the proportion of the first display area 101 relative to the display screen 100 is smaller, when the cathode voltage is adjusted, the cathode voltage can be provided for the smaller first display area 101 alone, and the cathode voltage of other areas (such as the second display area 102) is not required to be adjusted, so that the power consumption of the display screen 100 can be further reduced.
In some embodiments, as shown in fig. 4 and 5, the display screen 100 may include a plurality of first display regions 101. In the case that the first display area 101 is plural, plural cameras are correspondingly disposed below the screen of the first display area 101, so as to ensure that each camera can receive external light from above the display screen 100.
When the display screen 100 includes a plurality of first display regions 101, the voltage value of the first cathode 1011 corresponding to each first display region 101 may be the same, so that the display effect of each first display region 101 is the same.
As shown in fig. 4, the first cathode 1011 corresponding to each first display area 101 is connected to the same first driving circuit 201, or, as shown in fig. 5, the first cathode 1011 corresponding to each first display area 101 is connected to the corresponding first driving circuit 201, respectively.
When the voltage values of the first cathodes 1011 corresponding to each first display area 101 are the same, different first cathodes 1011 are connected to the same first driving circuit 201, so that the same cathode voltage can be provided for each first display area 101 when a plurality of first display areas 101 are simultaneously displayed, the display consistency of each first display area 101 is improved, the control is convenient, the circuits are fewer, and the circuit arrangement space of the display device can be reduced; when the voltage values of the first cathodes 1011 corresponding to each first display area 101 are the same, different first cathodes 1011 may be connected through different first driving circuits 201, so that the voltages of each first cathode 1011 may be controlled to make the display effects of the first display areas 101 the same, and simultaneously, the voltages of each first cathode 1011 may be accurately controlled through different first driving circuits 201 to improve the display control accuracy of the display device.
In some embodiments, as shown in fig. 5, when the display screen 100 includes a plurality of first display regions 101, the voltage value of the first cathode 1011 corresponding to each first display region 101 may be different, and at this time, the first cathode 1011 corresponding to each first display region 101 is connected to the corresponding first driving circuit 201.
Specifically, the light transmittance or the pixel distribution density of the plurality of first display regions 101 may be different, and thus, the voltage value provided to the corresponding first cathode 1011 of each first display region 101 may be different, and at this time, the voltage of the different first cathode 1011 is controlled by the different first driving circuit 201, and the corresponding voltage may be provided to the different first display regions 101 according to the display effect requirement, so as to ensure the same display effect.
In this embodiment, as shown in fig. 2, in a direction perpendicular to the display screen 100, the first cathode 1011 and the second cathode 1021 are arranged in the same layer to form a cathode layer 20. The first cathode 1011 and the second cathode 1021 arranged on the same layer can work together with the anode arranged on the other side of the pixel layer 10 to drive the pixel layer 10 to emit light; meanwhile, a first pixel of the first display area 101 is connected to the first cathode 1011, a second pixel of the second display area 102 is connected to the second cathode 1021, and the light emitting display of the first pixel and the second pixel is controlled by controlling the voltages of the first cathode 1011 and the second cathode 1021.
The thicknesses of the first cathode 1011 and the second cathode 1021 disposed in the same layer may be the same or different, and are not particularly limited in this application.
As shown in fig. 2, the display screen 100 may further include a substrate 30, the pixel layer 10 is formed on the substrate 30, and the cathode layer 20 is formed on the first surface of the pixel layer 10 and electrically connected to the pixel layer 10.

The first cathode unit is an independent electrode unit which is arranged in the same layer and has the same shape, and the second cathode unit is an independent electrode unit which is arranged in the same layer and has the same shape. The shapes of the first cathode unit and the second cathode unit may be the same or different, and the present application is not particularly limited.
The first cathode 1011 and the second cathode 1021 may be respectively formed as a monolithic structure, and the first cathode 1011 and the second cathode 1021 may be respectively vapor-deposited on the first surface of the pixel layer 10 to form the cathode layer 20; the first cathode 1011 and the second cathode 1021 may be formed integrally by vapor deposition on the first surface of the pixel layer 10.
The pixel layer 10 includes a plurality of pixel units corresponding to the primary colors one by one, wherein each pixel unit is filled with a luminescent material of the corresponding primary color, so that light incident into the pixel layer 10 is reflected. The pixel unit may be formed by vapor-depositing organic light emitting materials of different colors of red, green, and blue on an upper surface thereof, and may include, for example, a first pixel unit 11 emitting red light, a second pixel unit 12 emitting green light, and a third pixel unit 13 emitting blue light.
The first pixel of the first display area 101 and the second pixel of the second display area 102 may each include a plurality of pixel units, and the plurality of pixel units may be arranged in an array or may be arranged arbitrarily.
Alternatively, the substrate 30 may be a flexible substrate, which may be formed of an insulating material having flexibility, for example, a polymer material such as Polyimide (PI), polycarbonate (PC), polyethersulfone (PES), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), or the like.
The display screen 100 further includes an anode layer 40, where the anode layer 40 is formed on a second surface of the pixel layer 10 and is electrically connected to the pixel layer 10, and the second surface of the pixel layer 10 is disposed opposite to the first surface, that is, the anode layer 40 is located between the pixel layer 10 and the substrate 30, the pixel layer 10 is located between the anode layer 40 and the cathode layer 20, and the pixel layer 10 is electrically connected to the anode layer 40 and the cathode layer 20 respectively.
As shown in fig. 2, the anode layer 40 may include a plurality of anodes 41 disposed on the substrate 30 at intervals, and the plurality of anodes 41 are in one-to-one correspondence with the plurality of pixel units, so that each pixel unit has a corresponding anode voltage, thereby realizing independent control of the anode voltages of the respective pixel units.
The display 100 further includes an encapsulation layer (not shown) covering the cathode layer 20 to protect the display 100.
In this embodiment, the anode and the cathode of the first display area 101 are made of transparent materials, that is, the light transmittance of the first display area 101 can be improved by optimizing the materials of the first display area 101, so that the light more fully passes through the first display area 101 to collect images.
