Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present application in virtually any appropriately detailed structure.
The specification may use the phrases "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 in accordance with the application.
Fig. 1 is a schematic top view of a display screen of a display device provided in an embodiment of the present application, and fig. 2 is a side cross-sectional view of the display screen in fig. 1, as shown in fig. 1 and 2, an embodiment of the present application provides a display device, which includes a display screen 100, the display screen 100 includes a first display area 101 and a second display area 102, the first display area 101 is used for transmitting light when a camera is in operation;
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 effect of the first display area 101 and the second display area 102 in the first state is the same.
The first display region 101 is used not only for transmitting light when the camera is in operation but also for normal display when the camera is not in operation. That is, the first display area 101 can simultaneously satisfy the effects of light transmission and display, when the camera is not started, the display screen 100 normally works, and the screen of the first display area 101 is normally displayed as the screens 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 to enter the camera below the first display area 101, and the image acquisition effect and quality are ensured.
In this embodiment of the application, the first display area 101 has a first state and a second state, where the first state is a state in which the first display area 101 and the second display area 102 are displayed together, the second state is a state in which the first display area 101 and the camera cooperate to perform shooting, and the first state and the second state can be switched to each other.
In the first state, the display effect of the first display area 101 and the second display area 102 needs 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, so as to ensure the display effect of the display screen 100. Therefore, 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 applied to the cathode of the first display area 101 and the voltage applied to the cathode of the second display area 102, different voltages can be separately provided for the cathodes of the two display areas, so that the two display areas achieve the same display effect. For example, when the voltage of the cathode electrode required for the first display region 101 is high, the first display region 101 may be supplied with the high voltage alone without adjusting the voltage of the second display region 102, and the overall power consumption of the display device at the time of voltage adjustment may be reduced.
In a direction perpendicular to the display screen 100 (a normal direction of the display screen 100), the display screen 100 may include a pixel layer 10 (light emitting layer) and an anode and a cathode respectively provided on both side surfaces of the pixel layer 10. In operation of the display panel 100, positive and negative power supply voltages are applied to the anode and the 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 are recombined in the pixel layer to generate excitons that radiate energy from transition from an excited state to a ground state, causing the pixel layer 10 to emit light of a corresponding color. In which the anode positive voltage ELVDD is transmitted to the anode of the pixel layer 10 through the power supply signal line, the cathode negative voltage ELVSS is transmitted to the cathode of the pixel layer 10 through the power supply 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.
Illustratively, the display screen 100 may be a display screen employing self-luminous technology. For example, the display panel 100 may be an Organic Light-Emitting Diode (OLED) display panel, and an Organic Light-Emitting layer in the OLED display panel may serve as the pixel layer 10.
The display device provided by the embodiment of the application can enable the first display area 101 and the second display area 102 to achieve the same display effect in the first state by respectively adjusting the display parameters of the first display area 101 and the second display area 102, the processing burden of the display device cannot be increased, and the overall power consumption of the display device can be reduced.
In the embodiment of the present application, 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 can be seamlessly connected, so that after the display parameters of different display areas are adjusted to enable the displays of different display areas to be matched to achieve the same display effect, no display interruption or discontinuity occurs visually, and thus a better full-screen display effect can be achieved.
Fig. 1 is a schematic diagram of a structure of a display screen 100 in which a second display region 102 entirely surrounds a first display region 101. Actually, fig. 3 is a schematic top view of another display screen provided in this embodiment of the application, and as shown in fig. 3, the first display area 101 may be moved to a direction close to the 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 shown in fig. 3 is formed in which the second display area 102 partially surrounds the first display area 101. Hereinafter, the structure of the display screen 100 will be described with the second display region 102 surrounding the first display region 101 as a whole unless otherwise specified. The second display area 102 partially surrounds the first display area 101, and is not described in detail herein.
It is understood 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, both the first display region 101 and the second display region may not be displayed, and in this case, 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 effect is 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 perform shooting using the first display area 101 while displaying, 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 region 101 may display at a lower brightness so as to transmit light, the second display region 102 may display at a higher brightness normally, and the display effect of the first display region 101 and the second display region 102 is different, in which case, the display parameters of the first display region 101 and the second display region 102, such as the voltage applied to the cathode of the first display region 101 and the voltage applied to the cathode of the second display region 102, may be the same.
Further, the display screen 100 further includes:
a first cathode 1011, the first cathode 1011 providing a voltage to the first display region 101;
a second cathode 1021, wherein the second cathode 1021 provides voltage for the second display region 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 electrically connected with the first display area 101 and the second display area 102, different display areas can obtain corresponding cathode voltages according to the display effects of the different display areas, the cathode voltage of the display screen 100 does not need to be integrally adjusted, and the overall power consumption of the display screen 100 is reduced while the display effect of the display screen 100 is 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 region 101 and the second display region 102 are displayed together.
Since the first display region 101 needs to transmit light, the pixel distribution density of the first display region 101 is less than that of the second display region 102, i.e. the luminance of the first display region 101 is less than that of the second display region 102 under 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 displays of the first display area 101 and the second display area 102 can be matched with each other, 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 region 101;
the second driving circuit 202 is electrically connected to the second cathode 1021, and provides a second cathode voltage to the second cathode 1021 corresponding to the second display region 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 display of the first display area 101 can be matched with the display of the second display area 102 by respectively adjusting the first cathode voltage of the first cathode 1011 (first display area 101) and the second cathode voltage of the second cathode 1021 (second display area 102) through different driving circuits, the same display effect is achieved, the cathode voltage of the display screen 100 does not need 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 region 101 to the display screen 100 is small, when the voltage of the cathode is adjusted, the voltage of the cathode may be provided for the small first display region 101 alone, and the voltage of the cathode in other regions (for example, the second display region 102) does not need 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. Under the condition that the first display area 101 is multiple, a plurality of cameras are correspondingly arranged below the screen of the first display area 101, so that each camera can receive external light from the upper side of the display screen 100.
When the display panel 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.

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 display simultaneously, the display consistency of each first display area 101 is improved, the control is convenient, the number of circuits is small, and the circuit arrangement space of the display device can be reduced; the voltage values of the first cathodes 1011 corresponding to each first display area 101 are the same, different first cathodes 1011 can be connected through different first driving circuits 201, the voltage of each first cathode 1011 is controlled respectively, so that the display effect of each first display area 101 is the same, meanwhile, the voltage of each first cathode 1011 can be accurately controlled through different first driving circuits 201 connected to the corresponding first cathodes 1011, and the display control accuracy of the display device is improved.

Specifically, the light transmittance or the pixel distribution density of the plurality of first display regions 101 may be different, and therefore, the voltage values provided to the corresponding first cathodes 1011 of each first display region 101 may be different, and at this time, the voltages of the different first cathodes 1011 are controlled by the different first driving circuits 201, and corresponding voltages may be provided to the different first display regions 101 according to the display effect requirement, so as to ensure the same display effect.
