[0032] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application. The terms used in the implementation method section of the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0033] Figure 1 This is a schematic diagram of the structure of the first display panel provided in the embodiment of the present application. Figure 1As shown, the display panel may include a base substrate 1, a light emitting layer 2 and an encapsulation layer 3 stacked from bottom to top.

[0034] The substrate 1 includes a substrate 11 and a circuit layer 12 formed on the substrate 11. The substrate 11 may include a rigid substrate and a flexible substrate, wherein the rigid substrate may be made of materials such as glass, quartz, and organic polymer to reduce the manufacturing cost. The flexible substrate may be made of polyimide or polyethylene terephthalate to improve the flexibility of the display panel.

[0035] Considering that when the substrate 11 is a transparent substrate, the light generated by the light-emitting layer 2 may be emitted from the display device through the substrate 11, thereby causing light leakage. In some embodiments, the substrate 11 may be doped with light-shielding materials such as carbon black or black organic dyes to block light from emitting from the substrate 11.

[0036] It should be noted that if a conductive material is selected as the material of the substrate 11, in order to improve the reliability of the light-emitting layer 2, an insulating protective layer can be formed on the upper surface of the substrate 11. This can not only reduce the occurrence of short circuits, but also alleviate the lattice mismatch and thermal expansion coefficient mismatch between the subsequently formed film layer and the substrate 1, thereby improving the device performance and yield of the display panel.

[0037] The circuit layer 12 may include thin film transistors and metal wires arranged in an array. The thin film transistors may be connected to the metal wires to form a circuit layer of the display panel, which is used to drive the light-emitting layer 2 to emit light.

[0038] The light-emitting layer 2 may be an organic light-emitting diode (OLED) light-emitting layer. The light-emitting layer 2 may include a plurality of first pixel light-emitting structures 21 and a pixel definition structure 22 located between adjacent first pixel light-emitting structures 21. The first pixel light-emitting structure 21 may emit light under the driving action of the circuit layer 12. The pixel definition structure 22 may define a plurality of sub-pixel light-emitting areas to reduce light interference between adjacent sub-pixel light-emitting areas, thereby improving the color accuracy and detail performance of the displayed image.

[0039] Each pixel definition structure 22 may be provided with a groove 221, and the depth of the groove 221 may be set as required. A second pixel light emitting structure 2211 may be provided in the groove 221. Of course, in some embodiments, the number of the grooves 221 may also be multiple. Figure 1 For example, each pixel definition structure 22 is provided with a groove 221 , and the bottom of the groove 221 exposes the upper surface of the circuit layer 12 .

[0040] See also Figure 1, multiple first pixel light-emitting structures 21 are arranged at intervals, and the first pixel light-emitting structure 21 may include an anode layer 211, a light-emitting material layer 212, and a cathode layer 213 stacked along the light-emitting direction. Among them, the light-emitting material layer 212 may include an electron injection layer, an electron transport layer, an organic material layer, a hole transport layer, and a hole injection layer. The cathode layer 213 can generate electrons under the action of current, and the electrons are transmitted to the light-emitting material layer 212 through the electron injection layer and the electron transport layer. The anode layer 211 can generate holes under the action of current, and the holes are transmitted to the light-emitting material layer 212 through the hole injection layer and the hole transport layer. The holes and electrons can combine in the light-emitting material layer 212 to emit light.

[0041] It should be noted that the color of the light generated by the first pixel light-emitting structure 21 can be red, green or blue, and the light colors of adjacent first pixel structures can be different. The specific color can be selected according to actual needs by adjusting the material of the organic material layer, and the embodiments of the present application will not be repeated here.

[0042] The structure of the second pixel light emitting structure 2211 can refer to the first pixel light emitting structure 21, except that the light generated by the second pixel light emitting structure 2211 can be white light, or in some embodiments, light of other colors. For example, Figure 1 The light generated by the first pixel light-emitting structure 21 on the left side can be red light, the light generated by the first pixel light-emitting structure 21 on the right side can be green light, and the light color of the second pixel light-emitting structure 2211 can be blue light, so as to form a mixed color when anti-peeping is performed. The light color of the second pixel light-emitting structure 2211 can be selected according to actual needs, and this application does not make any special limitations here.

[0043] The first pixel light emitting structure 21 and the second pixel light emitting structure 2211 may be independent of each other through the pixel definition structure 22. Figure 1 The first pixel light emitting structure 21 and the second pixel light emitting structure 2211 may also be connected via a cathode material covering the pixel definition structure 22, so as to reduce the difficulty of preparation.

[0044] The encapsulation layer 3 can select one or more of inorganic encapsulation materials, organic encapsulation materials and inorganic-organic composite encapsulation materials. For example, inorganic-organic composite encapsulation materials can be selected. The inorganic-organic composite encapsulation materials can have the advantages of high water and oxygen barrier properties of inorganic encapsulation materials and good film-forming properties of organic encapsulation materials, and also have good light transmittance, thereby improving the reliability of the display panel.

[0045] An electrostrictive component 4 may be provided at a position in the encapsulation layer 3 corresponding to the pixel definition structure 22. When the display device is in a sharing mode with a wide viewing angle, the lower surface of the electrostrictive component 4 may cover the groove 221. In this way, on the one hand, the light of the second pixel light emitting structure 2211 may be blocked from interfering with adjacent sub-pixels. On the other hand, the electrostrictive component 4 may further reduce color mixing, improve the color accuracy of the display image, and thus improve the display quality.

[0046] See also Figure 1 , the electrostrictive component 4 may include a first electrode 41, an electrostrictive layer 42 and a second electrode 43. The controller (not shown) may be electrically connected to the first electrode 41 and the second electrode 43 respectively through wires, and may change the electric field between the first electrode 41 and the second electrode 43 by changing the voltage applied to the first electrode 41 and the second electrode 43. The controller may be located at any position of the display panel, and the embodiment of the present application does not impose any particular limitation on this. The first electrode 41 and the second electrode 43 may be embedded in the electrostrictive layer 42, so that the structure may be simplified. In some embodiments, the electrostrictive layer 42 may also be sandwiched between the first electrode 41 and the second electrode 43. The width of the first electrode 41 and the second electrode 43 is less than or equal to the width of the electrostrictive layer 42.

[0047] The electrostrictive layer 42 can shrink toward the light emitting direction under the driving action of the electric field, thereby changing the gap size between the lower surface of the electrostrictive component 4 and the notch of the groove 221 .

[0048] The electrostrictive layer 42 may include an electrostrictive material, and the internal molecules of the electrostrictive material may be polarized under the action of an external electric field, that is, the positive charge and the negative charge move in opposite directions, respectively, causing the electrostrictive material to shrink in the direction of the electric field until the elastic force and the electric attraction inside the electrostrictive material reach a balance. It should be noted that this deformation is reversible, which means that if the direction of the electric field changes, the deformation direction of the electrostrictive material will also change accordingly, that is, the electrostrictive material can return to its initial shape. The material of the electrostrictive layer 42 may include one or more of a dielectric elastomer, a liquid crystal elastomer, a ferroelectric polymer, an ionic polymer-metal composite material, a carbon nanotube, and an electrorheological body.

[0049] When preparing the encapsulation layer 3, the electrostrictive material layer can be formed by sputtering, and then etched into a specified shape by patterning processes such as exposure and development. After the electrostrictive layer 42 is formed, the encapsulation material is coated on the electrostrictive layer 42 to form the encapsulation layer 3.

[0050] The cross-sectional area of ​​the electrostrictive layer 42 may gradually increase along the light emitting direction. Figure 1 The longitudinal cross section of the electrostrictive layer 42 may be semicircular. Figure 2 A schematic diagram of the structure of a second display panel provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, compared to Figure 1 , Figure 2 The longitudinal section of the electrostrictive layer 42 is a triangle, and the portion of the electrostrictive layer 42 extending into the groove 221 can be selected according to actual needs. Of course, in actual products, the longitudinal section of the electrostrictive layer 42 can also be other shapes, such as a rectangle, a trapezoid or a special shape, etc., see Figure 3 .

[0051] Figure 4 for Figure 1 The display panel shown is a schematic diagram of a sharing mode, such as Figure 4 As shown, exemplarily, when the display device is in a sharing mode with a wide viewing angle, the second pixel light emitting structure 2211 may not emit light to reduce power consumption, or may emit light to reduce manufacturing costs. The controller may not output a voltage to the first electrode 41 and the second electrode 43, and the electrostrictive component 4 maintains its initial shape, so that the lower surface of the electrostrictive component 4 can be covered on the notch, thereby blocking the light emitted by the second pixel light emitting structure 2211 from emitting out of the groove 221, and the side view is visible. In some embodiments, the projection range of the groove 221 on the base substrate 1 can be located within the projection range of the electrostrictive layer 42 on the base substrate 1, so that the light blocking effect of the electrostrictive component 4 can be further improved.

[0052] Figure 5 for Figure 1 The schematic diagram of the display panel switching to the anti-peeping mode is shown in FIG. Figure 5 As shown, after the display device is switched from the sharing mode with a wide viewing angle to the anti-peeping mode with a narrow viewing angle, the controller can apply a driving electric field to the electrostrictive layer 42 through the first electrode 41 and the second electrode 43, and the electrostrictive layer 42 shrinks along the light emitting direction under the action of the driving electric field, so that the gap between the electrostrictive component 4 and the notch of the groove 221 can be increased, and the light emitted by the second pixel light emitting structure 2211 can be emitted from the groove 221. Taking the light emitted by the second pixel light emitting structure 2211 as white light as an example, the light emitted from the groove 221 and the light emitted by the adjacent first pixel light emitting structure 21 form a mixed color at a side viewing angle, thereby generating a color difference to interfere with the normal display of the picture, and then the person located at the side of the display panel can not clearly see the content displayed by the display panel, thereby achieving an anti-peeping effect.

[0053] akin, Figure 6 for Figure 2 The schematic diagram of the display panel switching to the anti-peeping mode is shown. Figure 7 for Figure 3The schematic diagram of the display panel switching to the anti-peeping mode shown in the figure, the description of the second display panel and the third display panel in the sharing mode and the anti-peeping mode can refer to the above related description. No further details will be given here.

[0054] It is understandable that the degree of contraction (related to the electric field strength) of the electrostrictive layer 42 is different, and the anti-peeping angle is also different, so that the anti-peeping range can be adjusted. When the display device is switched from the anti-peeping mode to the sharing mode, the controller changes the direction of the electric field applied to the electrostrictive layer 42 so that it can cover and stretch in the direction opposite to the light emitting direction, thereby covering the groove 221. Among them, the angle and amount of light emitted from the groove 221 are positively correlated with the size of the gap.

[0055] In a possible implementation, a light shielding layer 5 may be provided on the upper surface of the electrostrictive component 4, and the upper surface of the light shielding layer 5 may be flush with the encapsulation layer 3, thereby reducing the difficulty of preparation. The lower surface of the electrostrictive component 4 may be covered with a first reflective layer 6, so that in the anti-peep mode, the light entering the groove 221 of the adjacent first pixel light emitting structure 21 and / or the light generated by the second pixel light emitting structure 2211 ( Figure 5 The light is reflected by the first reflective layer 6 (indicated by the dotted arrow in the figure), and is emitted from the groove 221 through the gap, thereby improving the utilization rate of the light. The material of the first reflective layer 6 can be selected to be a flexible material so that it can always be attached to the lower surface of the electrostrictive component 4. Correspondingly, a second reflective layer 7 can also be provided on the pixel light-emitting structure provided in the groove 221 to further improve the utilization rate of the light. The second reflective layer 7 can be prepared from a transparent material in the prior art, and the embodiments of the present application will not be repeated here.

The technical solution provided by the present application can improve the flexibility of users' anti-peeping use.
