[0015] In some embodiments, in the first display mode, the control component adjusts the first refractive index to be greater than the second refractive index, and the second refractive index to be greater than the third refractive index, so that the light in the second refractive layer is emitted from the first refractive layer;

[0016] In the second display mode, the control component adjusts the first refractive index to be smaller than the second refractive index, and the second refractive index to be smaller than the third refractive index, so that the light in the second refractive layer is emitted from the third refractive layer;

[0017] In the transparent display mode, the control component adjusts the second refractive index to be smaller than the first refractive index, and the second refractive index to be smaller than the third refractive index, so that the light in the second refractive layer is emitted from the first refractive layer and the third refractive layer.

[0025] Beneficial effects of the present application: Different from the prior art, the present application provides a pixel structure and a display panel. The pixel structure is applied to a display panel, and includes a plurality of sub-pixel units and a plurality of reflective layers, and the plurality of sub-pixel units and the plurality of reflective layers are arranged to form a ring. By stacking the first refractive layer, the second refractive layer and the third refractive layer inside the ring, a transparent area is formed in the area surrounded by the ring, so that the light of each sub-pixel unit can enter the transparent area, and at the same time, the light is mixed in the transparent area under the reflection of the reflective layer, and after the light is mixed, it is refracted by the three refractive layers and emitted from both sides of the transparent area, so that the pixel structure can achieve transparent display in the transparent area, and effectively improve the display transparency of the pixel structure while ensuring the display brightness.

At the same time, by making the pixel structure further include a control component for adjusting the refractive index of the second refractive layer (the second refractive index), by adjusting the refractive index of the second refractive layer, the light in the second refractive layer can be totally reflected in the second refractive layer without being emitted, so that the light of the sub-pixel unit can only be emitted from the area where the sub-pixel unit is located (pixel area), and cannot be emitted from the transparent area, so as to achieve non-transparent display; or, by adjusting the second refractive index, the light in the second refractive layer can be emitted from the first refractive layer and the third refractive layer respectively, that is, the light of the sub-pixel unit can be emitted from the transparent area, so as to achieve transparent display. That is, the pixel structure provided by the present application can adjust the refractive index of the second refractive layer in the transparent area by the control component, so as to control the light incident on the second refractive layer to be totally reflected in the second refractive layer or to be emitted from the first refractive layer and the third refractive layer respectively, so that the pixel structure can be freely switched between non-transparent display and transparent display by adjusting the second refractive index by the control component.

DETAILED DESCRIPTION

[0043] The scheme of the embodiment of the present application is described in detail below in conjunction with the drawings of the specification.

[0044] In the following description, for the purpose of explanation rather than limitation, specific details such as specific system structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

[0045] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Thus, the features defined as "first", "second", "third" can expressly or implicitly include at least one of the features. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In the embodiments of this application, all directional indications (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0047] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0048] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0049] See also Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the planar structure of a display panel provided in the first embodiment of the present application, Figure 2 1 is a schematic diagram of a planar structure of a pixel structure provided in the first embodiment of the present application. In this embodiment, a display panel 100 is provided, the display panel 100 includes a driving substrate 10 and a plurality of pixel structures 20 disposed on the driving substrate 10, and the plurality of pixel structures 20 are arranged according to a preset rule.

[0050] Among them, the driving substrate 10 includes a plurality of sub-pixel driving circuits, and the sub-pixel driving circuits are electrically connected to the sub-pixel units 21 in the corresponding pixel structure 20, and are used to drive the sub-pixel units 21 to emit light to achieve a display function. Specifically, each pixel structure 20 includes a plurality of sub-pixel units 21 and a plurality of reflective layers 22, and the plurality of sub-pixel units 21 and the plurality of reflective layers 22 are arranged to form a ring. The plurality of pixel structures 20 are spliced ​​on the driving substrate 10 according to a preset rule, and can be specifically arranged and designed according to the shape of the pixel structure 20. For example, in the present embodiment, the plurality of sub-pixel units 21 and the plurality of reflective layers 22 are arranged to form a polygonal ring, so that the sub-pixel structure 20 is a polygon, and the sides of the adjacent pixel structures 20 with the same side length can be brought close to each other for splicing, so that the pixel structure 20 is arranged more compactly, thereby improving the pixel density.

[0051] Specifically, on the side of each pixel structure 20 close to the adjacent pixel structure 20, the sub-pixel unit 21 is arranged adjacent to the reflective layer 22, so that the light of the sub-pixel unit 21 is reflected back to the corresponding pixel structure 20, thereby avoiding the crosstalk of light in the adjacent pixel structure 20, resulting in problems such as color deviation and affecting the display effect. It can be understood that in the pixel structure 20, the outer side of each sub-pixel unit 21, that is, the side away from the inner part of the ring, is set as the reflective layer 22 of the adjacent pixel structure 20, so that when the sub-pixel unit 21 emits light, the light can be reflected back to the corresponding pixel structure 20 through the reflective layer 22, thereby avoiding the problem of crosstalk caused by the light of the sub-pixel unit 21 being incident on the adjacent pixel structure 20.

[0052] In the embodiment of the present application, in the pixel structure 20, the plurality of sub-pixel units 21 may be respectively a red sub-pixel 211, a green sub-pixel 212, and a blue sub-pixel 213, so as to realize color display. In the present embodiment, the pixel structure 20 is a hexagon, and in three adjacent pixel structures 20, three sides connected to the common ends of the three pixels close to each other form a "Y" shape, and the sub-pixel units 21 located on the three sides have different colors, that is, the sub-pixel units 21 located on the three sides may be respectively a red sub-pixel 211, a green sub-pixel 212, and a blue sub-pixel 213, so that the three sub-pixel units 21 on the three sides can constitute another pixel structure 20, so as to further improve the pixel density and pixel resolution.

[0053] Of course, in other embodiments, the sub-pixel units 21 on the three sides may also be set as sub-pixel units 21 with the same luminous color, which is beneficial to the preparation of the sub-pixel units 21. For example, the sub-pixel unit 21 may be an organic light emitting diode (OLED), and in every three adjacent pixel structures 20, the three sides close to each other are set as sub-pixel units 21 with the same luminous color, which is more beneficial to the evaporation process of the organic light emitting layer 215 and reduces the difficulty of the evaporation process.

[0054] See also Figure 3 , Figure 3 yes Figure 1Schematic diagram of the cross-sectional structure of an embodiment of the pixel structure in the AA direction. In this embodiment, the pixel structure 20 also includes a refractive component 23 and a control component 24 arranged inside the ring. The refractive component 23 includes a first refractive layer 231, a second refractive layer 232 and a third refractive layer 233 which are sequentially stacked inside the ring to form a transparent area 202 in the area surrounded by the ring. In the direction parallel to the plane where the ring is located, that is, in the direction parallel to the driving substrate 10, the second refractive layer 232 is overlapped with the sub-pixel unit 21, and the first refractive layer 231 and the third refractive layer 233 are staggered with the sub-pixel unit 21, so that the light of the sub-pixel unit 21 is only incident on the second refractive layer 232. That is, in the direction perpendicular to the driving substrate 10, the first refractive layer 231, the second refractive layer 232 and the third refractive layer 233 are sequentially stacked inside the ring, and in the direction parallel to the driving substrate 10, the second refractive layer 232 is overlapped with the sub-pixel unit 21, so that the light of the sub-pixel unit 21 can be incident on the second refractive layer 232, and the first refractive layer 231 and the third refractive layer 233 are staggered from the sub-pixel unit 21, that is, the first refractive layer 231 and the third refractive layer 233 are at different heights from the sub-pixel unit 21 in the direction perpendicular to the driving substrate 10, so that the light of the sub-pixel unit 21 cannot be incident on the first refractive layer 231 and the second refractive layer 232. The first refractive layer 231 has a first refractive index n1, the second refractive layer 232 has a second refractive index n2, and the third refractive layer 233 has a third refractive index n3.

[0055] The material of the second refractive layer 232 is an optical material with a variable refractive index, such as an electro-optical material or a magneto-optical material. The refractive index of the electro-optical material can change significantly under the action of an external electric field. The electro-optical material can include lithium niobate crystals, potassium dihydrogen phosphate, and non-ferroelectric oxide photorefractive crystals. The non-ferroelectric oxide photorefractive crystals mainly include bismuth silicate, bismuth germanate, and bismuth titanate. The refractive index of the magneto-optical material can change under the action of a magnetic field. The magneto-optical material can include antimagnetic materials such as ultra-high lead glass and arsenic sulfide glass, and paramagnetic materials such as terbium oxide glass and europium selenide crystals. Alternatively, the material of the second refractive layer 232 can also be a thermo-optical material, and its refractive index can change with temperature. That is, the refractive index of the second refractive layer 232 can change under the action of an electric field or a magnetic field, or can change the refractive index by temperature control, which is specifically determined by the specific material of the second refractive layer 232.

[0056] The control component 24 is used to adjust the refractive index of the second refractive layer 232, so that the light of the sub-pixel unit 21 incident into the second refractive layer 232 is totally reflected in the second refractive layer 232 or is emitted from the first refractive layer 231 and the second refractive layer 232 respectively. That is, the refractive index of the second refractive layer 232 is adjusted by the control component 24, so that the second refractive index n2 satisfies the corresponding relationship with the first refractive index n1 and the third refractive index n3, so that the light of the sub-pixel unit 21 incident into the second refractive layer 232 is totally reflected in the second refractive layer 232 and cannot enter the first refractive layer 231 and the third refractive layer 233, or the light of the sub-pixel unit 21 can enter the first refractive layer 231 and the third refractive layer 233 if the second refractive layer 232 is set, and is emitted after being refracted by the first refractive layer 231 and the third refractive layer 233 respectively.

[0057] It can be understood that in this embodiment, the second refractive index n2 of the second refractive layer 232 can be adjusted by the control component 24 so that the second refractive index n2 has a first relationship with the first refractive index n1 and the third refractive index n3, so that the light of the sub-pixel unit 21 incident on the second refractive layer 232 is totally reflected in the second refractive layer 232 and does not exit the transparent area 202, so that the light of the sub-pixel unit 21 can only exit from the area (pixel area 201) where the sub-pixel unit 21 is located, so as to achieve non-transparent display. At the same time, the second refractive index n2 can also be adjusted by the control component 24 so that the second refractive index n2 has a second relationship with the first refractive index n1 and the third refractive index n3, so that the light in the second refractive layer 232 can enter the first refractive layer 231 and the second refractive layer 232, and exit after being refracted by the first refractive layer 231 and the third refractive layer 233, respectively, that is, the light of the sub-pixel unit 21 incident on the second refractive layer 232 can exit on both sides of the transparent area 202, so as to achieve transparent display. Therefore, the second refractive index n2 of the second refractive layer 232 can be adjusted by the control component 24, so as to realize free switching of the pixel structure 20 between transparent display and non-transparent display, thereby realizing free switching of the display panel 100 between transparent display and non-transparent display.

[0058] like Figure 3As shown, specifically, the control component 24 includes a first electrode group 241, the first electrode group 241 includes a first transparent electrode 2411 and a second transparent electrode 2412, the first transparent electrode 2411 is arranged between the first refractive layer 231 and the second refractive layer 232, the second transparent electrode 2412 is arranged between the second refractive layer 232 and the third refractive layer 233, and the first electrode group 241 is used to generate a corresponding electric field or magnetic field to adjust the second refractive index n2. That is, the second refractive layer 232 is sandwiched between the first transparent electrode 2411 and the second transparent electrode 2412, so that the second refractive layer 232 is in the electric field or magnetic field generated by the first transparent electrode 2411 and the second transparent electrode 2412, thereby changing the second refractive index n2 under the action of the electric field or magnetic field, so that the light incident on the second refractive layer 232 by the sub-pixel unit 21 is totally reflected in the second refractive layer 232 or emitted from the first refractive layer 231 and the second refractive layer 232, thereby realizing non-transparent display or transparent display, and the second refractive index n2 can be controlled by the first electrode group 241, and freely switched between non-transparent display and transparent display. Specifically, the non-transparent display of the pixel structure 20 is the pixel area display mode, and the transparent display is the transparent display mode.

[0059] See also Figure 4 , Figure 4 yes Figure 3 Schematic diagram of the state of the pixel structure provided in the pixel area display mode. In this embodiment, the refractive index of the first refractive layer 231 is the same as that of the third refractive layer 233, that is, the first refractive index n1 is the same as the third refractive index n3. When the pixel structure 20 is switched to the pixel area display mode, the first electrode group 241 adjusts the second refractive index n2 to be greater than the first refractive index n1, and the light incident on the second refractive layer 232 by the sub-pixel unit 21 is totally reflected in the second refractive layer 232, and the light cannot be emitted from the transparent area 202. Therefore, in the pixel area display mode, the light of the sub-pixel unit 21 is only emitted in the pixel area 201, that is, in this mode, the display area of ​​the display panel 100 is located in the pixel area 201.

[0060] It can be understood that under the condition that the light in the second refractive layer 232 is totally reflected in the second refractive layer 232 and does not enter the first refractive layer 231 and the third refractive layer 233, the relationship between the second refractive index n2 and the first refractive index n1 can be obtained according to the principle of refraction of light, thereby obtaining the range of the second refractive index n2. Therefore, according to the principle of refraction of light, when the second refractive index n2 is greater than the first refractive index n1, and the difference between the second refractive index n2 and the first refractive index n1 is not less than the threshold value, the light of the sub-pixel unit 21 that is incident on the second refractive layer 232 is totally reflected in the second refractive layer 232 and cannot enter the first refractive layer 231 and the third refractive layer 233. Therefore, the light cannot be emitted from the transparent area 202, so that the light of the sub-pixel unit 21 is emitted only in the pixel area 201, thereby realizing the image display of the pixel area 201.

[0061] In this embodiment, the corresponding driving voltage can be transmitted to the first transparent electrode 2411 and the second transparent electrode 2412 respectively, so that a corresponding driving electric field is generated between the first transparent electrode 2411 and the second transparent electrode 2412, so as to drive the second refractive index n2 of the second refractive layer 232 to be greater than the first refractive index n1, thereby controlling the pixel structure 20 to switch to the pixel area display mode.

[0062] See also Figure 5 , Figure 5 yes Figure 3 Schematic diagram of the state of the pixel structure provided in the embodiment in the transparent display mode. Similarly, the refractive index of the first refractive layer 231 is the same as that of the third refractive layer 233, that is, the first refractive index n1 is the same as the third refractive index n3. In the transparent display mode, the first electrode group 241 adjusts the second refractive index n2 to be smaller than the first refractive index n1, and the light incident on the second refractive layer 232 by the sub-pixel unit 21 is emitted from the first refractive layer 231 and the third refractive layer 233 respectively. Therefore, in the pixel area display mode, the light of the sub-pixel unit 21 can be emitted on both sides of the transparent area 202, that is, in this mode, the transparent area 202 is reused as the display area, thereby realizing transparent display. It should be noted that the two sides of the transparent area 202 involved here refer to the opposite sides of the transparent area 202 in the direction perpendicular to the drive substrate 10.

[0063] According to the principle of light refraction, when the second refractive index n2 is less than the first refractive index n1, the light from the sub-pixel unit 21 incident on the second refractive layer 232 can enter the first refractive layer 231 and the third refractive layer 233 to be refracted, and the light is emitted after being refracted by the first refractive layer 231 and the third refractive layer 233. Therefore, the light from the sub-pixel unit 21 incident on the second refractive layer 232 can be emitted from both sides of the transparent area 202, thereby realizing transparent display. It can be understood that in the pixel structure 20, the light from the red sub-pixel 211, the green sub-pixel 212, and the blue sub-pixel 213 is incident on the second refractive layer 232, and at the same time, the light is also reflected by the reflective layer 22, so that the three different colors of light are mixed in the second refractive layer 232, thereby displaying the corresponding colors.

[0064] In this embodiment, the corresponding driving voltage can be transmitted to the first transparent electrode 2411 and the second transparent electrode 2412 respectively, so that a corresponding driving electric field is generated between the first transparent electrode 2411 and the second transparent electrode 2412, so as to drive the second refractive index n2 of the second refractive layer 232 to be smaller than the first refractive index n1, thereby controlling the pixel structure 20 to switch to the transparent display mode.

[0065] In the embodiment of the present application, the sub-pixel unit 21 includes an anode electrode 214, a light-emitting layer 215, and a cathode electrode 216, which are sequentially stacked in a direction perpendicular to the plane where the ring is located. Among them, the cathode electrode 216 and / or the anode electrode 214 are transparent electrodes, or the anode electrode 214 and / or the cathode electrode 216 are reflective electrodes. That is, the cathode electrode 216 and the anode electrode 214 of the sub-pixel unit 21 can be a transparent electrode and a reflective electrode, respectively, or a reflective electrode and a transparent electrode, respectively, or both are transparent electrodes, or both are reflective electrodes, which can be specifically set according to display needs.

[0066] For example, in this embodiment, the anode electrode 214 is a reflective electrode and the cathode electrode 216 is a transparent electrode, so that when the pixel structure 20 is in the pixel area display mode, the light of the sub-pixel unit 21 is only emitted from the cathode electrode 216 area, so that the display panel 100 only displays the picture on the side where the cathode is located, and the other side does not emit light; in the transparent display mode, on the side where the cathode is located, the light of the sub-pixel unit 21 can be emitted from the pixel area 201 and the transparent area 202 in the area where the cathode is located, so that the brightness of the display panel 100 on the side where the cathode is located is greater than the brightness on the other side, so that the display panel 100 can achieve double-sided display, and can also adapt to an environment where one side is darker and the other side is brighter, and can also switch to a single-sided display mode, which can better protect privacy.

[0067] Alternatively, in another embodiment, the cathode electrode 216 and the anode electrode 214 are both transparent electrodes, so that when the pixel structure 20 is in the pixel area display mode, the light of the sub-pixel unit 21 can be emitted on both sides of the pixel area 201, so that the display panel 100 can achieve double-sided display. In this mode, the display area of ​​the display panel 100 is small and the brightness is low, which can be used in darker environments and scenes to improve the comfort of eye viewing; in the transparent display mode, the light of the sub-pixel unit 21 can be emitted on both sides of the pixel area 201 and the transparent area 202, that is, the display area includes the pixel area 201 and the transparent area 202, which increases the area of ​​the display area. At the same time, since the light in the second refractive layer 232 can be emitted in the transparent area 202, the display brightness is improved, so that the display panel 100 can also be used in brighter environments and scenes to improve the display effect; this setting method enables the display panel 100 to be applicable to more scenes.

[0068] See also Figure 6 , Figure 6 yes Figure 1 2 is a schematic cross-sectional structure diagram of another embodiment of the pixel structure in the AA direction. In this embodiment, the control component 24 includes a first electrode group 241, a second electrode group 242 and a third electrode group 243. The structure and function of the first electrode group 241 are similar to Figure 3 The first electrode group 241 in the embodiment has the same structure and function, and can achieve the same technical effect, and the specifics can refer to the above related introduction. The second electrode group 242 includes a third transparent electrode 2421 and a first transparent electrode 2411, and the third transparent electrode 2421 is arranged on the side of the first refractive layer 231 away from the second refractive layer 232, and the second electrode group 242 is used to generate a corresponding electric field or magnetic field to adjust the first refractive index n1 of the first refractive layer 231; that is, the first transparent electrode 2411 in the first electrode group 241 is also reused as one of the electrodes in the second electrode group 242. The third electrode group 243 includes a second transparent electrode 2412 and a fourth transparent electrode 2431, and the fourth transparent electrode 2431 is arranged on the side of the third refractive layer 233 away from the second refractive layer 232, and the third electrode group 243 is used to generate a corresponding electric field or magnetic field to adjust the third refractive index n3; that is, the second transparent electrode 2412 in the first electrode group 241 is also reused as one of the electrodes in the third electrode group 243.

[0069] It can be understood that the first refractive layer 231 is sandwiched between the first transparent electrode 2411 and the third transparent electrode 2421, so that the first refractive layer 231 can change the first refractive index n1 under the action of the electric field or magnetic field generated by the first transparent electrode 2411 and the third transparent electrode 2421. The second refractive layer 232 is sandwiched between the first transparent electrode 2411 and the second transparent electrode 2412, so that the second refractive layer 232 can change the second refractive index n2 under the action of the electric field or magnetic field generated by the first transparent electrode 2411 and the second transparent electrode 2412. The third refractive layer 233 is sandwiched between the second transparent electrode 2412 and the fourth transparent electrode 2431, so that the third refractive layer 233 can change the third refractive index n3 under the action of the electric field or magnetic field generated by the second transparent electrode 2412 and the fourth transparent electrode 2431. Through the above arrangement, the first refractive index n1, the second refractive index n2 and the third refractive index n3 can be adjusted respectively by the first electrode group 241, the second electrode group 242 and the third electrode group 243, so as to control the state of the light incident on the second refractive layer 232 from the sub-pixel unit 21: total reflection occurs in the second refractive layer 232, or is emitted from the first refractive layer 231, or is emitted from the second refractive layer 232, or is emitted from the first refractive layer 231 and the second refractive layer 232 respectively. Thus, the display panel 100 has more display modes to meet more different usage scenarios.

[0070] It should be noted that in the above embodiments, the control component 24 needs to be insulated from the anode electrode 214 and the cathode electrode 216 of the sub-pixel unit 21 to avoid signal crosstalk leading to abnormal light emission of the sub-pixel unit 21 and abnormal second refractive index n2, resulting in display mode switching failure or damage to the sub-pixel unit 21. Specifically, in the present embodiment, the control component 24 and the anode electrode 214 and the cathode electrode 216 of the sub-pixel unit 21 are respectively arranged in different film layers, so that the control component 24 and the anode electrode 214 and the cathode electrode 216 of the sub-pixel unit 21 are insulated from each other. This arrangement allows the second refractive layer 232 to be in direct contact with the light-emitting layer 215, and also allows the electrode of the control component 24 to completely cover the second refractive layer 232, so that all the light of the sub-pixel unit 21 can enter the second refractive layer 232, avoiding light leakage to the first refractive layer 231 and the third refractive layer 233, thereby affecting the display effect in the pixel area display mode.

[0071] Alternatively, in one embodiment, an insulating layer may be provided on one side of the sub-pixel unit 21 close to the inner part of the ring, that is, an insulating layer may be provided between the control component 24 and the sub-pixel unit 21, so as to insulate the sub-pixel unit 21 from the control component 24. Alternatively, in another embodiment, the end of the second refractive layer 232 close to the sub-pixel unit 21 is convex along two opposite sides of the direction perpendicular to the second refractive layer 232, so as to insulate the control component 24 from the anode electrode 214 and the cathode electrode 216.

[0072] See also Figure 7 , Figure 7 yes Figure 6 Schematic diagram of the state of the pixel structure 20 provided in the embodiment in the pixel area display mode. Specifically, in the pixel area display mode, the control component 24 adjusts the second refractive index n2 to be greater than the first refractive index n1 and greater than the third refractive index n3, so that the light of the sub-pixel unit 21 incident on the second refractive layer 232 is totally reflected in the second refractive layer 232 and does not emit from the transparent area 202. The light of the sub-pixel unit 21 is only emitted from the pixel area 201, so that the light emitting area is only located in the pixel area 201.

[0073] See also Figure 8 , Figure 8 yes Figure 6 Schematic diagram of the state of the pixel structure provided in the embodiment in the first display mode. In the first display mode, the control component 24 adjusts the first refractive index n1 to be greater than the second refractive index n2, and the second refractive index n2 to be greater than the third refractive index n3, so that the light incident on the second refractive layer 232 of the sub-pixel unit 21 can enter the first refractive layer 231, and is emitted after being refracted by the first refractive layer 231, and the third refractive index n3 of the third refractive layer 233 is less than the second refractive index n2 of the second refractive layer 232, so that the light cannot enter the third refractive layer 233. Therefore, in this display mode, the transparent area 202 is displayed only on one side of the first refractive layer 231. Through the setting of the anode electrode 214 and the cathode electrode 216, single-sided display or double-sided display can also be achieved. Specifically, the types (transparent electrode, reflective electrode) of the anode electrode 214 and the cathode electrode 216 can be set according to actual needs to meet different usage requirements.

[0074] Specifically, the correspondence between the driving voltages of the first transparent electrode 2411, the second transparent electrode 2412, the third transparent electrode 2421 and the fourth transparent electrode 2431 and the first refractive index n1, the second refractive index n2 and the third refractive index n3 can be obtained through testing, so that according to the correspondence, the first refractive index n1, the second refractive index n2 and the third refractive index n3 can be adjusted by controlling the driving voltages of the first transparent electrode 2411, the second transparent electrode 2412, the third transparent electrode 2421 and the fourth transparent electrode 2431 to switch different display modes of the display panel 100.

[0075] See also Fig. 9 , Fig. 9 yes Figure 6 Schematic diagram of the state of the pixel structure provided in the embodiment in the second display mode. In the second display mode, the control component 24 adjusts the first refractive index n1 to be smaller than the second refractive index n2, and the second refractive index n2 to be smaller than the third refractive index n3, so that the light incident on the second refractive layer 232 of the sub-pixel unit 21 can enter the third refractive layer 233, and is emitted after being refracted by the third refractive layer 233, and the first refractive index n1 of the first refractive layer 231 is smaller than the second refractive index n2 of the second refractive layer 232, so that the light cannot enter the first refractive layer 231. Therefore, in this display mode, the transparent area 202 is displayed only on one side of the third refractive layer 233. Through the setting of the anode electrode 214 and the cathode electrode 216, single-sided display or double-sided display can also be achieved. Specifically, the types (transparent electrode, reflective electrode) of the anode electrode 214 and the cathode electrode 216 can be set according to actual needs to meet different usage requirements.

[0076] See also Fig.10 , Fig.10 yes Figure 6 Schematic diagram of the state of the pixel structure provided in the embodiment in the transparent display mode. In the transparent display mode, the control component 24 adjusts the second refractive index n2 to be smaller than the first refractive index n1, and the second refractive index n2 is smaller than the third refractive index n3, so that the light in the second refractive layer 232 is emitted from the first refractive layer 231 and the third refractive layer 233. That is, in this display mode, the display area includes the pixel area 201 and the transparent area 202, which increases the area of ​​the display area. At the same time, since the light in the second refractive layer 232 can be emitted from the transparent area 202, the display brightness is improved, so that the display panel 100 can also be used in brighter environments and scenes to improve the display effect; this setting method enables the display panel 100 to be used in more scenes. In this display mode, the first refractive index n1 and the third refractive index n3 can also be adjusted by the second electrode group 242 and the third electrode group 243 respectively to adjust the viewing angle to meet the viewing angle requirements of different display surfaces.

[0077] In this embodiment, an insulating layer is further provided on the side of the sub-pixel unit 21 close to the inner part of the ring, so that the control component 24 and the anode electrode 214 and the cathode electrode 216 are insulated from each other, thereby avoiding a short circuit between the control component 24 and the electrodes of the sub-pixel unit 21, resulting in signal crosstalk and causing abnormalities in the sub-pixel unit 21 and the refractive index.

[0078] Please continue reading Figure 1In this embodiment, the shape of the pixel structure 20 is a polygon, and the sub-pixel unit 21 and the reflective layer 22 are arranged to form a polygonal ring. Each side of the polygonal ring includes a sub-pixel unit 21 or a reflective layer 22, and the red sub-pixel 211, the green sub-pixel 212 and the blue sub-pixel 213 are arranged adjacent to each other in sequence, and multiple reflective layers 22 are arranged adjacent to each other in sequence.

[0079] Specifically, each sub-pixel unit 21 constitutes one side of the polygonal ring, each reflective layer 22 constitutes one side of the polygonal ring, and the side where the red sub-pixel 211 is located, the side where the green sub-pixel 212 is located, and the side where the blue sub-pixel 213 is located are connected, and the sides where the multiple reflective layers 22 are located are connected. In this embodiment, taking the pixel structure 20 as a hexagon as an example, the red sub-pixel 211, the green sub-pixel 212, the blue sub-pixel 213 and the three reflective layers 22 are arranged to form a hexagonal ring, and a transparent area 202 is formed inside the ring, so that the opposite side of each sub-pixel unit 21 is the reflective layer 22, so as to improve the display brightness, and at the same time, by using the principle of light reflection, the light of the sub-pixel unit 21 can be mixed in the transparent area 202, thereby improving the light mixing effect.

[0080] In this embodiment, a plurality of pixel structures 20 are spliced ​​together to form a honeycomb structure, so as to improve the compactness and structural stability of the pixel structures 20 , and also improve the material utilization efficiency of the sub-pixel unit 21 .

[0081] Furthermore, in the pixel structure 20 , a black matrix BM is disposed between adjacent sub-pixel units 21 and between adjacent sub-pixel units 21 and the reflective layer 22 to isolate adjacent sub-pixel units 21 and avoid cross-color problems between adjacent sub-pixel units 21 .

[0082] See also Fig.11 , Fig.11 2 is a schematic diagram of a planar structure of a display panel provided in the second embodiment of the present application. Different from the first embodiment, in the present embodiment, in the pixel structure 20, the adjacent two sides of each sub-pixel unit 21 are reflective layers 22. That is, the sub-pixel units 21 and the reflective layers 22 are alternately arranged along the circumference of the polygon, so that the light of the sub-pixel unit 21 can be better mixed in the transparent area 202, improving the uniformity of the mixed light, thereby improving the display effect of the display panel 100.

[0083] See also Fig.12 , Fig.12is a schematic diagram of the planar structure of the display panel provided in the third embodiment of the present application. Different from the first and second embodiments, in this embodiment, the length of the side where the blue sub-pixel 213 of each pixel structure 20 is located is greater than the length of the side where the red sub-pixel 211 is located, and is greater than the length of the side where the green sub-pixel 212 is located. That is, in the direction parallel to the driving substrate 10, the extension length of the blue sub-pixel 213 is greater than the extension length of the red sub-pixel 211, and is also greater than the extension length of the green sub-pixel 212.

[0084] In this embodiment, the sub-pixel unit 21 is an OLED light-emitting device. Due to the different luminous efficiencies of organic light-emitting materials of different colors, red usually has the highest luminous efficiency, followed by green, and blue has the lowest luminous efficiency. In order to improve the luminous efficiency of the blue sub-pixel 213 and extend the service life of the blue sub-pixel 213, in this embodiment, the extension length of the blue sub-pixel 213 is made greater than the extension length of the red sub-pixel 211 and the extension length of the green sub-pixel 212, so that the luminous efficiency of the sub-pixel units 21 of different colors is more balanced, and the aging degree of the sub-pixel units 21 of different colors is also more balanced, so as to avoid the display panel 100 from having problems such as color deviation as the use time increases. Furthermore, the extension length of the reflective layer 22 on the opposite side of the blue sub-pixel 213 is the same as the extension length of the blue sub-pixel 213, so as to increase the reflection area, improve the reflection efficiency, and further improve the display brightness.

[0085] See also Fig.13 , Fig.13 : is a schematic diagram of the planar structure of the display panel provided in the fourth embodiment of the present application. Different from the above embodiments, in this embodiment, each side of the polygonal ring includes at least one sub-pixel unit 21 and at least one reflective layer 22, the sub-pixel units 21 and the reflective layer 22 are arranged alternately in sequence along the circumference of the ring, and the luminous color of the sub-pixel unit 21 on each side of the polygonal ring is different from the luminous color of the sub-pixel unit 21 on the adjacent side.

[0086] Through the above arrangement, the pixel structure 20 includes a plurality of sub-pixel units 21 of the same color, and the plurality of sub-pixel units 21 of the same color can be respectively distributed on at least two non-adjacent sides of the polygon, and each side is provided with a sub-pixel unit 21 and a reflective layer 22, so that the sub-pixel unit 21 and the reflective layer 22 are distributed more evenly, and the uniformity of light mixing is further improved. Taking the hexagonal pixel structure 20 as an example, in this embodiment, a plurality of sub-pixel units 21 of the same color are distributed on two opposite sides of the polygon, one side includes a sub-pixel unit 21 and two reflective layers 22, and the sub-pixel unit 21 is located between the two reflective layers 22, and the opposite side includes two sub-pixel units 21 and a reflective layer 22, and the reflective layer 22 is located between the two sub-pixels, so that the sub-pixel units 21 and the reflective layer 22 on the two opposite sides are staggered, so that the position directly opposite to each sub-pixel unit 21 is set as the reflective layer 22, thereby improving the reflection efficiency.

[0087] Furthermore, in the hexagonal pixel structure 20, the number of sub-pixel units 21 on two adjacent sides is different. For example, one sub-pixel unit 21 and two reflective layers 22 are arranged on one side, and two sub-pixel units 21 and one reflective layer 22 are arranged on the side adjacent to the hexagonal pixel structure 20. Such an arrangement makes the sub-pixel units 21 and the reflective layer 22 more evenly distributed on the polygonal pixel structure 20, thereby further improving the light mixing uniformity of the transparent area 202.

[0088] In this embodiment, the number of sub-pixel units 21 is increased through the above configuration, which can not only improve the light mixing uniformity, but also improve the display brightness of the pixel structure 20, thereby improving the display brightness and display effect of the display panel 100.

[0089] See also Fig.14 , Fig.14 1 is a schematic diagram of the structure of a display device provided in an embodiment of the present application. In this embodiment, a display device is provided, and the display device includes a display panel 100 as provided in the above embodiment. The pixel structure 20 of the display panel 100 is arranged as described above, and the same technical effect can be achieved, which can not only increase the area of ​​the transparent area 202, improve the transparency during transparent display, and enhance the transparent display effect, but also enable the display device to have multiple display modes, and can switch the corresponding display mode according to different usage scenarios, which can meet the display requirements of multiple scenarios.

[0090] Furthermore, the display device may also include a control module 200, which is electrically connected to the control component 24 in the display panel 100 to provide a corresponding driving voltage to the control component 24, thereby controlling the first refractive index n1 of the first refractive layer 231, the second refractive index n2 of the second refractive layer 232, and the third refractive index n3 of the third refractive layer 233 in the pixel structure 20, thereby controlling the display panel 100 to switch to a corresponding display mode.
