Description
Technical Field
The present invention relates to display technologies, and in particular, to a display panel and a display device.
Background
With the development of display technology, full-screen or high-screen display screens become a research hotspot.
In order to make the display device have the front camera shooting function and the full-screen display function, the technology of the camera under the screen is developed. However, in this scheme, the display effect and the imaging quality of the display area at the position corresponding to the image pickup area are conflicting with each other, and if the display effect of this area is ensured, the area of the light transmission area is necessarily limited, which makes it difficult to meet the requirement of image pickup for light; if the area of the transmissive region is increased to ensure the image quality and the transmittance of the ambient light is increased, the brightness of the pixel structure in the region is inevitably reduced, which results in poor display effect in the region. Therefore, how to ensure the whole display effect of the display panel and ensure higher imaging quality is the problem to be solved urgently by the technology of the camera under the screen.

In a second aspect, based on the same inventive concept, an embodiment of the present invention further provides a display device, including the display panel provided in the above aspect.
In the display panel provided in the embodiment of the present invention, the first anode of the first light emitting device in the first display area has an electrostrictive structure, and the electrostrictive structure is in an original shape in a power-off state and is subjected to an expansion deformation in a power-on state, so that the electrostrictive structure has a first coverage area in a display (power-on) stage and a second coverage area in an imaging (power-off) stage in a thickness direction of the display panel, and the first coverage area is larger than the second coverage area. The electroluminescent expansion structure has larger coverage area in the display stage, so that most of light emitted from the organic light emitting layer to the non-display side can be reflected to the display side again, and the display effect of the first display area is ensured; because the electrostriction structure possesses less coverage area at the formation of image stage, therefore can guarantee the regional area of printing opacity in the first display area, can guarantee promptly that sufficient ambient light can pass through the module of making a video recording of printing opacity regional incidence to display panel below, guarantee the imaging quality.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures. The various implementation modes provided by the embodiment of the invention can be combined and implemented without contradiction.
Fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present invention, fig. 2 is a schematic structural diagram of the display panel in the first display area in fig. 1 at a display stage, and fig. 3 is a schematic structural diagram of the display panel in the first display area in fig. 1 at an imaging stage. Referring to fig. 1 to 3, the display panel 01 includes: a base substrate 100; a plurality of pixels including a first pixel including a first light emitting device 200; a display area including a first display area 10, the first light emitting device 200 being located in the first display area 10, the first light emitting device 200 including a first anode 210, the first anode 210 including an electro-expansive structure 211; a display stage (fig. 2) in which the electro-expansive structure 211 has a first coverage area in the thickness direction of the display panel; an imaging phase, in which the electro-expansive structure 211 has a second coverage area in the thickness direction of the display panel (fig. 3); the first coverage area is greater than the second coverage area.
The first display area 10 may be, for example, a display area corresponding to a setting area of the camera module, and the first light emitting device 200 in the first display area 10 is designed as follows, so that the first display area 10 has a good display effect in a display stage, and sufficient ambient light can be incident to the camera module below the display panel through the display panel in an imaging stage.
A light emitting device generally includes an anode, an organic light emitting layer, and a cathode. In this embodiment, the first anode 210 of the first light emitting device 200 in the first display region 10 includes an electro-expansive structure 211. The structure 211 is in its original shape in the de-energized state and undergoes an expansive deformation in the energized state. In this way, the first coverage area of the electro-expansion structure 211 in the display stage may be larger than the second coverage area of the electro-expansion structure 211 in the imaging stage by energizing the electro-expansion structure 211 in the display stage to provide the first coverage area in the thickness direction of the display panel and de-energizing the electro-expansion structure 211 in the imaging stage to provide the second coverage area in the thickness direction of the display panel. Optionally, the thickness direction of the display panel is a direction perpendicular to the plane of the substrate base plate 100; the first coverage area is the area of the vertical projection of the electro-expansion structure 211 on the substrate base plate 100 during the display phase; the second footprint is the area of the vertical projection of the electro-expansive structure 211 on the substrate base plate 100 during the imaging phase.
Fig. 2 shows a state of the electroluminescent structure 211 in a display stage, and it can be seen from fig. 2 that the electroluminescent structure 211 has a larger coverage area in the display stage due to the electrical expansion, so that most of light emitted from the organic light emitting layer 220 to the non-display side can be reflected to the display side again, thereby improving the light emitting efficiency and ensuring the display effect of the first display area 10. Fig. 3 shows the state of the electrostrictive structure 211 in the imaging phase, and as can be seen from fig. 3, the electrostrictive structure 211 is in the original state due to being in the power-off state, and has a smaller coverage area in the imaging phase, so that the area of the light-transmitting area in the first display area 10 can be ensured, that is, enough ambient light can be ensured to be incident to the camera module below the display panel through the light-transmitting area, the transmittance of the ambient light is increased, and the imaging quality is ensured.
As shown in fig. 3, optionally, in the imaging stage, since the coverage area of the electrostrictive structure 211 is small, an accommodating space is provided between the electrostrictive structure 211 and the pixel defining layer 300, the accommodating space may correspond to the light-transmitting area in the imaging stage, and the accommodating space may provide an accommodating space for deformation of the electrostrictive structure 211, so that the electrostrictive structure 211 expands into the accommodating space after being powered on, thereby increasing the coverage area. It should be noted that, a person skilled in the art may use any technical means to form the accommodating space, and the embodiment of the present invention does not limit this.
For example, fig. 2 and fig. 3 illustrate the thin film transistor 400 in the pixel driving circuit of the display panel for transmitting an electrical signal. As shown in fig. 2 and 3, alternatively, the output terminal of the thin film transistor 400 may be electrically connected to the electro-expansive structure 211. In the display phase (fig. 2), the tft 400 is turned on, and an electrical signal is transmitted to the electro-expansive structure 211 through the tft 400, so that the electro-expansive structure 211 is electrically expanded. Since the electroluminescent expansion structure 211 has a large coverage area, most of the light emitted from the organic light emitting layer 220 to the non-display side can be reflected to the display side again, thereby ensuring the display effect of the first display region 10. In the imaging phase (fig. 3), the thin film transistor 400 is turned off, the electroluminescent structure 211 maintains the original state, the first light emitting device 200 does not emit light, and the ambient light is incident to the camera module under the display panel through the light transmitting area.
It should be noted that in other embodiments, the power on/off control of the electrostrictive structure 211 can be realized in other manners, and the manner shown in fig. 2 and 3 is only one possible manner, but not a limitation, and will be described in detail later.
In the display panel provided in the embodiment of the present invention, the first anode of the first light emitting device in the first display area has an electrostrictive structure, and the electrostrictive structure is in an original shape in a power-off state and is subjected to an expansion deformation in a power-on state, so that the electrostrictive structure has a first coverage area in a display (power-on) stage and a second coverage area in an imaging (power-off) stage in a thickness direction of the display panel, and the first coverage area is larger than the second coverage area. The electroluminescent expansion structure has larger coverage area in the display stage, so that most of light emitted from the organic light emitting layer to the non-display side can be reflected to the display side again, and the display effect of the first display area is ensured; because the electrostriction structure possesses less coverage area at the formation of image stage, therefore can guarantee the regional area of printing opacity in the first display area, can guarantee promptly that sufficient ambient light can pass through the module of making a video recording of printing opacity regional incidence to display panel below, guarantee the imaging quality. Therefore, the technical scheme of the embodiment of the invention can solve the problem of conflict between the display effect and the imaging quality, so that the display device with the display panel can have excellent full-screen display effect and imaging quality.
Alternatively, the electro-expansive structure 211 is an electro-expansive colloidal crystal material including at least styrene and ferrocene derivatives. The material of the electrostrictive structure 211 may be selected by a person skilled in the art according to the requirement, and the embodiment of the present invention is not limited thereto.
Optionally, the electrostrictive structure 211 is doped with a metal oxide; the metal oxide includes alumina or titania.
By doping the metal oxide in the electroluminescent expansion structure 211, the light shielding capability of the electroluminescent expansion structure 211 can be further improved, more light emitted from the organic light emitting layer 220 is reflected to the display side, the light emitting efficiency is improved, and the display effect of the first display area 10 is improved.
Fig. 4 is a schematic structural diagram of another display panel located in the first display area according to an embodiment of the present invention, referring to fig. 4, optionally, the first anode 210 further includes an electrostrictive structure 212, and the electrostrictive structure 212 is connected to the electrostrictive structure 211 and is disposed on the same layer; the light transmittance of the electrostrictive structure 212 is greater than the light transmittance of the electrostrictive structure 211; in the display stage, the electrostrictive structure 212 has a third coverage area in the thickness direction of the display panel; in the imaging phase, the electrostrictive structure 212 has a fourth coverage area in the thickness direction of the display panel; the third coverage area is less than the fourth coverage area.
When the imaging phase is switched to the display phase, the electrostrictive structure 211 needs to have a certain expansion space, i.e., the accommodating space described above. However, the implementation difficulty of this scheme is relatively large from a process point of view, and the performance of the first light emitting device 200 may be degraded due to the partial region under the organic light emitting layer 220 being suspended. In order to reduce the process difficulty and ensure the performance of the first light emitting device 200, the embodiment further provides the electrostrictive structure 212 connected to the electrostrictive structure 211 and disposed on the same layer, and the electrostrictive structure 212 realizes the effects of transmitting light, providing an accommodating space for the electrostrictive structure 211, and the like.
For example, fig. 4 shows the structure of the display panel at the first display area 10 during the imaging stage, as shown in fig. 4, the electrostrictive structure 212 may be disposed between the electrostrictive structure 211 and the pixel defining layer 300, so that an electrical signal received by the electrostrictive structure 211 may be transmitted to the electrostrictive structure 212, and the electrostrictive structure 212 may deform accordingly according to the presence or absence of the electrical signal. In the display stage, the electrostrictive structure 212 is shrunk by electricity, and the original fourth coverage area is reduced to the third coverage area, so that a certain accommodating space can be provided for the deformation of the electrostrictive structure 211, the coverage area of the electrostrictive structure 211 is enlarged, and the display effect of the first display area 10 is ensured. In the imaging stage, the electrostrictive structure 212 is in an original state, and since the light transmittance of the electrostrictive structure 212 is greater than that of the electrostrictive structure 211, ambient light can penetrate through the area where the electrostrictive structure 212 is located and enter the camera module below the display panel, thereby realizing the camera function.
Optionally, the electrostrictive structure 212 includes at least one of an all organic composite, a dielectric electroactive polymer, an electrostrictive grafted elastomer, an electrostrictive film, an electroviscoelastic polymer, a ferroelectric polymer, and a liquid crystal elastomer. The material of the electrostrictive structure 212 may be selected by those skilled in the art according to the requirement, and the embodiment of the present invention is not limited thereto.
It should be noted that the electrostrictive structure 211 and the electrostrictive structure 212 may be disposed in a surrounding manner or in a juxtaposed manner, which is not limited in this embodiment of the present invention, as long as the electrostrictive structure 212 can provide an accommodating space for the electrostrictive structure 211 in at least one direction after being shrunk by receiving electricity. In addition, the embodiment of the present invention does not limit the manner in which the electrostrictive structure 212 receives the electrical signal, and those skilled in the art can set the method according to actual situations, and will be described as an example.
It should be further noted that, a person skilled in the art may reasonably set the second coverage area of the electroluminescent structure 211 and the fourth coverage area of the electroluminescent structure 212 according to the deformation capability of the electroluminescent structure 211 and the electroluminescent structure 212, the coverage area of the organic light-emitting layer 220 in the thickness direction of the display panel, and the like, so as to enable sufficient ambient light to pass through the display panel and ensure the image quality, and enable the first coverage area of the electroluminescent structure 211 after being electrically expanded to be sufficient to re-reflect most of the light emitted from the organic light-emitting layer 220 to the non-display side to the display side, and ensure the display effect of the first display area 10.
Fig. 5 is a schematic structural diagram of another display panel located in the first display area according to an embodiment of the present invention, referring to fig. 5, further optionally, the first anode 210 further includes a first fixed conductive structure 213; the first fixed conductive structure 213 is connected to the electro-expandable structure 211 and/or the electro-collapsible structure 212, and at least part of the first fixed conductive structure 213, the electro-expandable structure 211 and the electro-collapsible structure 212 are arranged in layers.
It is understood that the conductive performance of the electrostrictive structure 211 and the electrostrictive structure 212 is relatively poor compared to metal or other conductive materials, and therefore, only using the electrostrictive structure 211 and the electrostrictive structure 212 as the first anode 210 may decrease the mobility of electrons and holes, resulting in poor light emitting performance of the first light emitting device 200, which may affect the display effect. Therefore, in order to ensure the light emitting performance of the first light emitting device 200, the present embodiment adds the first fixed conductive structure 213 to the above embodiment, and at least a portion of the first fixed conductive structure 213 is disposed in the same layer as the electroluminescent expansion structure 211 and the electroluminescent contraction structure 212, so that the first fixed conductive structure 213 and the organic light emitting layer 220 can be fixedly and electrically connected, for example, electrically connected by a fixed contact, thereby improving the mobility of electrons and holes and ensuring the light emitting performance of the first light emitting device 200. For example, the first fixed conductive structure 213 may be a metal and/or a metal oxide, such as indium tin oxide, which is not limited in the embodiments of the present invention.
It should be noted that fig. 5 illustrates the first fixed conductive structure 213 connected to the expandable structure 211 and the expandable structure 211 connected to the collapsible structure 212, in other embodiments, the first fixed conductive structure 213 may also be connected to the collapsible structure 212, or both the expandable structure 211 and the collapsible structure 212, which is not limited in this embodiment of the present invention, as long as any one of the three structures is not independently disposed.
The structure of the first anode 210 and the manner in which the electro-expansive and electro- contractible structures 211 and 212 receive electrical signals will be described in further detail below on the basis of an alternative embodiment in which the first anode 210 includes the first fixed conductive structure 213, the electro-expansive structure 211, and the electro-contractible structure 212.
Specifically, the light emitting condition of the first light emitting device 200 is controlled by the output signal of the thin film transistor 400 in the pixel driving circuit, the output terminal of the thin film transistor 400 has an electrical signal in the display stage, and the output terminal of the thin film transistor 400 has no electrical signal in the imaging stage, so that the output signal of the thin film transistor 400 can be transmitted to the electro-expandable structure 211 and the electro-contractible structure 212 through the first fixed conductive structure 213, so that the electro-expandable structure 211 is electrically expanded in the display stage, the electro-contractible structure 212 is electrically contracted in the display stage, and both are maintained in the original state in the imaging stage. In addition, signal routing may also be specially provided, and the electrostrictive structure 211 and the electrostrictive structure 212 are electrically connected to the driving integrated circuit through the signal routing, so as to implement transmission of an electrical signal.
Here, first, the structure of the first anode 210 will be described in detail with respect to a mode of transmitting an electric signal through the thin film transistor 400 and the first fixed conductive structure 213.
As shown in fig. 5, the display panel further includes a pixel driving circuit; the pixel driving circuit includes a plurality of thin film transistors 400, and an output terminal of the thin film transistor 400 is electrically connected to the first fixed conductive structure 213. In this way, the output signal of the thin film transistor 400 can be transmitted to the first fixed conductive structure 213, so that the light emitting performance of the first light emitting device 200 can be ensured, and the states of the electrostrictive structure 211 and the electrostrictive structure 212 can be controlled.
It should be noted that fig. 5 illustrates the thin film transistor 400 as a bottom-gate structure, and in other embodiments, the thin film transistor 400 may also adopt a top-gate structure, which is shown in fig. 6 for a structural schematic diagram of a display panel located in the first display region according to an embodiment of the present invention. One skilled in the art can select either a top-gate thin film transistor or a bottom-gate thin film transistor, and the structure of the thin film transistor is not limited by the embodiment of the present invention.
Optionally, the first fixed conductive structure 213 is electrically connected to the electro-expandable structure 211 and/or the electro-collapsible structure 212.
Fig. 5 only illustrates the first fixed conductive structure 213 electrically connected to the electrostrictive structure 211, and in other embodiments, the first fixed conductive structure 213 may also be electrically connected to the electrostrictive structure 212, or both the electrostrictive structure 211 and the electrostrictive structure 212, which is not limited in this embodiment of the present invention, as long as it is ensured that an electrical signal can be transmitted to the electrostrictive structure 211 and the electrostrictive structure 212.
In particular, the first fixed conductive structure 213 may have different structures, and the electrostrictive structure 211 and the electrostrictive structure 212 may have different arrangements corresponding to the different structures of the first fixed conductive structure 213, as follows:
with continued reference to fig. 5, optionally, the first fixed conductive structure 213 includes a first sub-portion 2131, the electro-expansive structure 211, and the electro-contractible structure 212 being disposed in layers.
In this embodiment, the first fixed conductive structure 213 only includes the first sub-portion 2131 disposed in the same layer as the electro-expandable structure 211 and the electro-shrinkable structure 212, and signals are transmitted to the electro-expandable structure 211 and the electro-shrinkable structure 212 through the first sub-portion 2131.
To achieve the above purpose, optionally, the first sub-portion 2131 is electrically connected to the electro-expandable structure 211, and the electro-expandable structure 211 is electrically connected to the electro-shrinkable structure 212, or the first sub-portion 2131 is electrically connected to the electro-expandable structure 211 and the electro-shrinkable structure 212, respectively.
Fig. 7-12 are schematic structural diagrams of different first anodes provided by an embodiment of the invention, and exemplarily show several schematic top-view structural diagrams of the first anode 210 when the first fixed conductive structure 213 includes only the first sub-portion 2131.
Specifically, when the first fixed conductive structure only includes the first sub-portion 2131 and the first sub-portion 2131 is electrically connected to only the electrostrictive structure 211 or the electrostrictive structure 212, it is preferable that the first sub-portion 2131 be electrically connected to the electrostrictive structure 211 and the electrostrictive structure 211 be electrically connected to the electrostrictive structure 212, as shown in fig. 7 to 10. With such an arrangement, in the display stage, after the electric expansion structure 211 is powered on, the electric expansion structure 211 expands in a direction away from the first sub-portion 2131 (close to the electric contraction structure 212), so that the electric expansion structure 211 and the electric contraction structure 212 are always kept in contact, an electric signal can be transmitted to the electric contraction structure 212, the electric contraction structure is powered on, and an accommodating space is provided for the electric expansion structure 211. On the contrary, if the first sub-portion 2131 is electrically connected to the electrostrictive structure 212, in the displaying stage, since the electrostrictive structure 212 is electrically shrunk, a gap may occur between the electrostrictive structure 212 and the electrostrictive structure 211, which may cause a phenomenon that the electrostrictive structure 211 cannot expand due to failure to receive an electrical signal, and therefore, to avoid this phenomenon, it is preferable that the first sub-portion 2131 is electrically connected to the electrostrictive structure 211, and the electrostrictive structure 211 is electrically connected to the electrostrictive structure 212.
Illustratively, the first anode 210 may be configured such that the electrostrictive structure 212 is disposed around the electrostrictive structure 211, the electrostrictive structure 211 is disposed around the first section 2131 (fig. 7), the first section 2131 is disposed around the electrostrictive structure 211, the electrostrictive structure 211 is disposed around the electrostrictive structure 212 (fig. 8), and the first section 2131, the electrostrictive structure 211, and the electrostrictive structure 212 may be sequentially disposed side by side in any direction parallel to the plane of the substrate 100 (fig. 9 and 10). In particular, the edges of the electrostrictive structure 211 and the electrostrictive structure 212 are preferably arc-shaped (as shown in fig. 7 to 8), so that the diffraction problem during photographing can be reduced, and the imaging quality can be improved. In addition, since the first sub-portion 2131 (the first fixed conductive structure 213) is electrically connected to the thin film transistor 400 through the through hole, when the first sub-portion 2131 is located at the center, the process difficulty is high, and the first sub-portion 2131 may be disposed at the edge of the first anode 210 (as shown in fig. 8 to 10) to reduce the process difficulty. The setting can be selected by those skilled in the art according to the requirement, and the embodiment of the invention is not limited to this.

Any arrangement manner may be selected by a person skilled in the art as required, and the embodiment of the present invention is not limited thereto, as long as it is ensured that both the electrostrictive structure 211 and the electrostrictive structure 212 can receive an electrical signal, and the electrostrictive structure 212 can provide an accommodating space for the electrostrictive structure 211 in at least one direction after being shrunk by electricity.

In this embodiment, the first fixed conductive structure 213 includes a second sub-portion 2132 electrically connected to the first sub-portion 2131, in addition to the first sub-portion 2131. Since the difficulty of the process of electrically connecting the first sub-portion 2131 to the through hole is high, in this embodiment, the second sub-portion 2132 is disposed on the side of the first sub-portion 2131 close to the substrate 100, and the first sub-portion 2131 is electrically connected to the through hole through the second sub-portion 2132, so as to reduce the difficulty of the process. Among them, the second sub-portion 2132 may be electrically connected to the pixel driving circuit through a via hole or a contact at a place not overlapping with the first sub-portion (in the thickness direction of the display panel).
Specifically, the second sub-portion 2132 is in contact with and electrically connected to at least the first sub-portion 2131 to realize transmission of electrical signals. In other embodiments, optionally, the electro-expansive structure 211 is in contact with and electrically connected to the second section 2132; and/or, the electrostrictive structure 212 is in contact with and electrically connected to the second section 2132.
Fig. 14 is a schematic structural diagram of another display panel located in the first display area according to an embodiment of the present invention, and fig. 14 illustrates an example that the second sub-portion 2132 is in contact with and electrically connected to the first sub-portion 2131, the electro-expansive structure 211 and the electro-contractive structure 212 at the same time, so that an electrical signal can be transmitted to the electro-expansive structure 211 and the electro-contractive structure 212 through the second sub-portion 2132, and stability of transmission of the electrical signal can be ensured. In other embodiments, the second portion 2132 can also be electrically connected to the first portion 2131 and the electro-expandable structure 211, and the second portion 2132 can also be electrically connected to the first portion 2131 and the electro-shrinkable structure 212, for example, the second portion 2132 can be electrically connected to the electro-shrinkable structure 212 when the electro-shrinkable structure 212 is not electrically connected to the first portion 2131. In general, the present invention is not limited to the embodiment as long as the first part 2131 and/or the second part 2132 can transmit the electric signal to the electrostrictive structure 211 and the electrostrictive structure 212.
Taking the structure shown in fig. 14 as an example, since the second part 2132 is electrically connected to both the electrostrictive structure 211 and the electrostrictive structure 212, the first anode 210 may be arranged, for example, in the following manner in addition to the structures shown in fig. 7 to 10: first, the electrostrictive structure 211 is disposed around the electrostrictive structure 212, and the electrostrictive structure 212 is disposed around the first sub portion 2131; second, the first sub-portion 2131 is disposed around the electrostrictive structure 212, and the electrostrictive structure 212 is disposed around the electrostrictive structure 211; third, the first sub-portion 2131, the electrostrictive structure 212 and the electrostrictive structure 211 are arranged side by side in this order in any direction parallel to the plane of the substrate base 100. In general, when the second section 2132 is electrically connected to both the electro-expandable structure 211 and the electro-collapsible structure 212, either the electro-expandable structure 211 or the electro-collapsible structure 212 may be connected to the first section 2131 with less requirements for the positional relationship than if the first fixed conductive structure 213 included only the first section 2131.
Further, when the second section 2132 is in contact with and electrically connected to the electro-expansive structure 211 and/or the electro-contractible structure 212, at least a portion of the second section 2132 is required to be transparent in order to ensure that ambient light can pass through the display panel during the imaging phase. With continued reference to fig. 14, optionally, the second section 2132 includes a first transparent portion 2132-1 and a first non-transparent portion 2132-2, the first transparent portion 2132-1 does not overlap the first section 2131 and the first non-transparent portion 2132-2 overlaps the first section 2131 in a thickness direction of the display panel. In addition, optionally, the second partition 2132 is a transparent structure, which is shown in fig. 15 for illustrating a schematic structural diagram of another display panel located in the first display area according to an embodiment of the present invention.
The second section 2132 may be entirely transparent to allow ambient light to pass through the display panel. In addition, since the metal conductivity is better than that of the transparent conductive structure, in order to improve the conductivity of the electrical signal while ensuring the light transmittance, only the second sub-portion 2132 (i.e., the first transparent portion 2132-1) corresponding to the electrostrictive structure 211 and/or the electrostrictive structure 212 may be provided as a transparent structure such as indium tin oxide, and the second sub-portion 2132 (i.e., the first non-transparent portion 2132-2) corresponding to the first sub-portion 2131 may be provided as a non-transparent structure such as metal. The present invention is not limited to the above embodiments, and the present invention can be implemented by any method.
It should be noted that fig. 13-15 show different filling patterns between the first part 2131 and the second part 2132, but in other embodiments, the first part and the second part may be made of the same material, or may be completed in the same process, and the embodiment of the present invention is not limited thereto.
In the above embodiments, the first fixed conductive structure 213 may include only the first sub-portion 2131, or both the first sub-portion 2131 and the second sub-portion 2132, and with reference to fig. 15, optionally, the first fixed conductive structure 213 further includes a third sub-portion 2133, the third sub-portion 2133 is located on a side of the first sub-portion 2131 away from the substrate base plate 100, and the third sub-portion 2133 is electrically connected to the first sub-portion 2131; the electro-expansive structure 211 is in contact with and electrically connected to the third subsection 2133, and the electro-contractible structure 212 is in contact with and electrically connected to the third subsection 2133; the first pixel further includes an organic light emitting layer 220, and the organic light emitting layer 220 is located on a side of the third partition 2133 away from the substrate 100.
Fig. 15 is only an example of the first fixed conductive structure 213 including the first sub-portion 2131, the second sub-portion 2132, and the third sub-portion 2133, and other possible manners are not described herein again. It is understood that, during the switching between the imaging phase and the display phase, the electrostrictive structure 211 and the electrostrictive structure 212 may deform, and if the electrostrictive structure 211 and the electrostrictive structure 212 are in direct contact with the organic light emitting layer 220, abrasion may be caused to the organic light emitting layer 220, which may affect the light emitting performance of the first light emitting device 200. In this embodiment, by providing the third partition 2133, the organic light emitting layer 220 can be isolated from the electroluminescent expansion structure 211 and the electroluminescent contraction structure 212, so that the organic light emitting layer 220 is prevented from being damaged by friction, and the performance and the service life of the first light emitting device 200 are ensured.
Similarly to the arrangement of the second part 2132, at least a part of the third part 2133 is required to be transparent in order to ensure that the ambient light can pass through the display panel during the imaging period. With continued reference to fig. 15, optionally, third section 2133 is a transparent structure. Fig. 16 is a schematic structural diagram of another display panel located in the first display area according to an embodiment of the present invention, and referring to fig. 16, optionally, the third sub-portion 2133 includes a second transparent portion 2133-1 and a second non-transparent portion 2133-2, where in the thickness direction of the display panel, the second transparent portion 2133-1 does not overlap with the first sub-portion 2131, and the second non-transparent portion 2133-2 overlaps with the first sub-portion 2131.
The third partition 2133 may be entirely transparent to allow ambient light to pass through the display panel. In addition, since the metal conductivity is due to the conductivity of the transparent conductive structure, in order to improve the conductivity of the electrical signal while ensuring the light transmittance, only the third portion 2133 (the second transparent portion 2133-1) corresponding to the electrostrictive structure 211 and/or the electrostrictive structure 212 may be provided as a transparent structure such as indium tin oxide, and the third portion 2133 (the second non-transparent portion 2133-2) corresponding to the first portion 2131 may be provided as a non-transparent structure such as metal. The present invention is not limited to the above embodiments, and the present invention can be implemented by any method.
It should be noted that fig. 15-16 show that the first part 2131 and the third part 2133 may be made of different materials with different fillings, in other embodiments, the first part 2131 and the third part 2133 may be made of the same material, or may be completed in the same process, and the embodiment of the present invention is not limited thereto.
In summary, the above embodiments describe the structure of the first anode 210 in detail with respect to the way of transmitting electrical signals through the thin film transistor 400 and the first fixed conductive structure 213, and the following describes the way of electrically connecting the electrostrictive structure 211 and the electrostrictive structure 212 with the driving ic circuit through the signal traces to achieve the transmission of electrical signals.
For example, fig. 17 is a schematic structural diagram of another display panel located in the first display area according to an embodiment of the present invention, referring to fig. 17, and optionally, the display panel further includes signal traces 500, where the signal traces 500 are electrically connected to the electrostrictive structure 211 and the electrostrictive structure 212, respectively.
The electrostrictive structure 211 and the electrostrictive structure 212 can be electrically connected with the driving integrated circuit through the signal routing 500, so that the electrostrictive structure and the electrostrictive structure are correspondingly deformed according to the output signal of the driving integrated circuit. The signal routing 500 is specially arranged for the electric expansion structure 211 and the electric contraction structure 212 to transmit electric signals, so that the driving integrated circuit can independently control the light emitting state of the first light emitting device 200 and the deformation of the electric expansion structure 211 and the electric contraction structure 212, the transmission of data signals and the transmission of deformation signals are not affected with each other, the first light emitting device can normally emit light, and the electric expansion structure and the electric contraction structure can normally generate deformation.
Optionally, the signal trace 500 may be disposed on the same layer as the source and drain of the thin film transistor 400, or on the same layer as the gate of the thin film transistor 400, and fig. 17 illustrates an example in which the signal trace 500 is disposed on the same layer as the source and drain. The metal film layer can be prevented from being increased due to the arrangement, so that the thickness of the display panel is prevented from being increased.
It should be noted that, when the signal trace 500 is separately disposed, the first fixed conductive structure 213 may still adopt the structure provided in any of the above embodiments, and details thereof are not repeated herein. In order to ensure the independence of signal transmission, an insulation arrangement is required between the first fixed conductive structure 213 and the electrostrictive structure 211 and/or the electrostrictive structure 212, and for example, an insulation layer 501 (see fig. 17) may be provided between the first fixed conductive structure 213 and the electrostrictive structure 211 and/or the electrostrictive structure 212.
It should be further noted that in other embodiments, electrical signals may be transmitted to the electrostrictive structure 211 and the electrostrictive structure 212 through the thin film transistor 400 and the signal trace 500 at the same time, and in this case, no insulation is required between the first fixed conductive structure 213 and the electrostrictive structure 211 and the electrostrictive structure 212. So set up, can guarantee when first fixed conducting structure 213 transmission deformation signal breaks down, the deformation signal can be walked 500 through the signal and transmit to electrically-induced expansion structure 211 and electrically-induced contraction structure 212, perhaps when the signal is walked 500 transmission deformation signal and is broken down, the deformation signal can be passed through thin film transistor 400 and first fixed conducting structure 213 and transmit to electrically-induced expansion structure 211 and electrically-induced contraction structure 212, guarantee the steady transmission of deformation signal, thereby guarantee that first display area 10 can successfully carry out the switching in display phase and imaging phase. The method can be set by a person skilled in the art according to the needs, and the embodiment of the invention is not limited thereto.
In summary, the first fixed conductive structure 213 of the first anode 210 may include only the first part 2131, may include both the first part 2131 and the second part 2132, may include both the first part 2131 and the third part 2133, and may include both the first part 2131, the second part 2132 and the third part 2133. For the first fixed conductive structures 213 with different structures, the first, second and third sub-portions 2131, 2132 and 2133 may have various arrangements, respectively; the electrostrictive structure 211 and the electrostrictive structure 212 may also have various configurations. Regardless of the configuration of the first anode 210, the thin film transistor 400 and/or the signal trace 500 can be used to transmit electrical signals through the electrostrictive structure 211 and the electrostrictive structure 212 of the thin film transistor.

Therefore, the light emitted from the organic light emitting layer of the second light emitting device 600 to the non-display side can be reflected to the display side by the second fixed conductive structure 613, so that the light emitting efficiency is improved, and the display effect is improved. The first display area 10 realizes high light transmittance in the imaging stage and high light emitting efficiency in the display stage by arranging the electrostrictive structure 211 and the electrostrictive structure 212, so that the display device with the display panel has excellent full-screen display effect and imaging quality.
For example, the resolution of the first display area may be set to be smaller than the resolution of the second display area, so as to ensure that the area of the light-permeable area in the first display area is sufficient to meet the requirement of the camera on the light transmission amount. Further, a transition region may be provided between the first display region and the second display region, and the resolution of the transition region is made to be intermediate between the first display region and the second display region to ensure display uniformity. Furthermore, in the drawings in the embodiments of the present invention, the pixel driving circuit electrically connected to the first light emitting device is located in the first display area as an example, in other embodiments, optionally, the pixel driving circuit electrically connected to the first light emitting device may be further disposed at a position corresponding to the transition area, so as to improve the light transmittance of the first display area in the imaging stage and improve the imaging quality.
Optionally, the resolution of the first display area is equal to the resolution of the second display area.
Alternatively, a transition region may be provided between the first display region and the second display region, and the resolution of the transition region may be made equal to that of the first display region.
