In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application.

[0046] See also Figure 1 The present invention provides a display panel comprising a substrate 1, a light-emitting layer 2, an isolation plate 3, an encapsulation layer 4, and a viewing angle switching assembly 5. The substrate 1 is used to support components disposed thereon. The substrate 1 is not specifically limited in type in this embodiment and may be a glass substrate, for example. The light-emitting layer 2 is disposed on the substrate 1, the isolation plate 3 surrounds the light-emitting layer 2, and the encapsulation layer 4 is disposed on a side of the isolation plate 3 away from the substrate 1. The substrate 1, isolation plate 3, and encapsulation layer 4 cooperate to form a closed accommodating cavity. The display panel comprises multiple isolation plates 3, correspondingly forming multiple accommodating cavities.

[0047] The viewing angle switching component 5 is disposed in the accommodating cavity and corresponds to the accommodating cavity one by one. Since the viewing angle switching component 5 is disposed in the accommodating cavity and contains charged particles 52, the substrate 1, the isolation plate 3 and the packaging layer 4 are all insulating components.

[0048] The viewing angle switching component 5 includes a side wall electrode 51 arranged on the side wall of the isolation plate 3 and a charged particle 52 arranged in the accommodating cavity. The outer surface of the charged particle 52 includes a light absorption area, and the light absorption area faces the accommodating cavity. The light emitted by the light-emitting layer 2 is irradiated on the light absorption area of ​​the charged particle 52 and is absorbed by the charged particle 52. No light is reflected out. The charged particle 52 can be an ink particle, etc.

[0049] The charged particles carry a charge of a first polarity. When the privacy protection mode is selected, the electrical properties of the sidewall electrodes 51 are controlled to be opposite to those of the charged particles 52, that is, the sidewall electrodes are configured to carry a charge of a second polarity. The first polarity and the second polarity are different. In the privacy protection mode, the charged particles 52 are adsorbed onto the sidewall electrodes 51, with the light absorption area facing the accommodation cavity. Therefore, if Figure 1 As shown, light incident on the sidewalls of the isolation plate 3 is absorbed by the light absorption region of the charged particles 52. When the user views the display axially, the light incident on the central region of the cavity is received by the human eye, allowing the user to see the display normally. When an observer views the display off-axis, the light incident on the sidewalls is blocked and absorbed by the light absorption region of the charged particles 52, preventing the light from passing through. Therefore, the observer cannot observe the displayed image, thus reducing the viewing angle of the display panel and achieving a privacy protection effect. It should be noted that the electrical properties of the charged particles 52 shown in the figure are merely illustrative and should not be construed as being limited to this.

[0050] When the non-peeping mode is selected, the electrical properties of the sidewall electrodes 51 are controlled to be the same as those of the charged particles 52, and the charged particles 52 are not adsorbed onto the sidewall electrodes 51. Figure 2 As shown, light striking the sidewalls of the isolation plate 3 is reflected. When the user is viewing the display axially, the light entering the central region of the cavity is received by the eye, allowing the user to see the display normally. When the observer is viewing the display off-axis, the light striking the sidewalls is reflected by the sidewall electrodes 51 and ultimately emitted randomly, allowing the observer to see the display without affecting the original viewing angle of the display panel.

[0051] If it is necessary to explain, the sidewall electrodes 51 can be set on the sidewalls of the isolation plates 3 in the corresponding direction based on the viewing angle direction that needs to be restricted, or the electrical properties of the sidewall electrodes 51 can be controlled. For example, if the viewing angles on all sides of the display panel need to be restricted, sidewall electrodes 51 are set on the inner side of the isolation plates 3 in each direction, and the electrical properties of each sidewall electrode 51 are controlled at the same time. In addition, if it is only necessary to limit the user's viewing angle in the left and right directions, the inner sidewalls of the two relatively arranged isolation plates 3 are selected to set the sidewall electrodes 51 and then control them, or sidewall electrodes 51 are set on the inner side of the isolation plates 3 in each direction, but when controlling the sidewall electrodes 51, only the sidewall electrodes 51 in the corresponding direction are connected, and the sidewall electrodes 51 set in other directions are not connected or are set oppositely.

[0052] The charge polarity of the sidewall electrode 51 can be adjusted by adjusting the voltage value input to the sidewall electrode 51. In the non-peeping mode, the sidewall electrode 51 receives a first voltage value and is configured to have a charge of a first polarity. In the anti-peeping mode, the sidewall electrode 51 receives a second voltage value and is configured to have a charge of a second polarity.

[0053] In this embodiment, sidewall electrodes 51 and charged particles 52 are added to the sidewalls of the isolation plate 3. By controlling the electrical properties of the sidewall electrodes 51 to adsorb the charged particles 52, switching between the sharing and anti-peeping modes is achieved without significantly increasing the thickness of the display panel.

[0054] In one embodiment, the viewing angle switching component 5 further includes charged reflective particles (not shown in the figure) provided in the accommodating cavity. The charged reflective particles and the charged particles 52 are different particles. The electrical properties of the charged particles 52 are different from those of the charged reflective particles, that is, the charged particles carry a charge of a second polarity. When the anti-peeping mode is selected, the electrical properties of the control sidewall electrode 51 are opposite to those of the charged particles 52, and the charged particles 52 are adsorbed onto the sidewall electrode 51. When the non-anti-peeping mode is selected, the electrical properties of the control sidewall electrode 51 are the same as those of the charged particles 52, and the charged reflective particles are adsorbed onto the sidewall electrode 51. The light incident on the sidewall is repeatedly reflected by the charged reflective particles adsorbed on the sidewall electrode 51 and finally emitted randomly. Compared with light reflected only by the sidewall electrode 51, the viewing angle of the display panel is larger.

[0055] In one embodiment, Figure 3 and Figure 4 As shown, in addition to setting two types of particles, charged particles 52 and charged reflective particles, charged particles 52 can be set to include both a light-absorbing area and a reflective area, wherein the light-absorbing area absorbs light and the reflective area reflects light. A light-absorbing layer and a reflective layer can be coated on the charged particles 52 to form corresponding light-absorbing areas and reflective areas, respectively. The electrical properties of the light-absorbing area are different from those of the reflective area. In any mode, the charged particles 52 are adsorbed on the sidewall electrodes 51. The difference is that, for example, Figure 3 As shown, when the anti-peeping mode is selected, the electrical properties of the sidewall electrode 51 are controlled to be the same as those of the light-absorbing area and opposite to those of the reflective area. Then, the charged particles 52 are adsorbed onto the sidewall electrode 51, and one side of the reflective area is close to the sidewall electrode 51, while the other side of the light-absorbing area is far away from the sidewall electrode 51. Then, light enters the light-absorbing area and no light is reflected out, thereby achieving an anti-peeping effect. On the contrary, if Figure 4 As shown, when the non-peeping mode is selected, the electrical properties of the sidewall electrode 51 are controlled to be opposite to those of the light-absorbing area and the same as those of the reflective area, so that the charged particles 52 are adsorbed onto the sidewall electrode 51, one side of the light-absorbing area is close to the sidewall electrode 51, and one side of the reflective area is far away from the sidewall electrode 51, then the light enters the light-absorbing area and is reflected multiple times, thereby achieving the effect of expanding the viewing angle.

[0056] In one embodiment, when the outer surface of the charged particle 52 includes both a light absorption area and a reflection area, in order to ensure that no light enters the reflection area and is reflected out in the anti-peeping mode, the area of ​​the light absorption area is set to be greater than or equal to the area of ​​the reflection area.

[0057] In one embodiment, Figure 5 As shown, the display panel also includes a light-emitting unit 21 disposed within each receiving cavity. The light-emitting unit 21 is disposed on the substrate 1 and corresponds to each pixel, illuminating the corresponding pixel. A viewing angle switching component 5 is disposed between the light-emitting unit 21 and the encapsulation layer 4. Light emitted by the light-emitting unit 21 enters the corresponding receiving cavity, and the corresponding viewing angle switching component 5 is used to switch the anti-peeping mode.

[0058] In one embodiment, Figure 5 As shown, the light-emitting unit 21 includes an anode layer 211, a light-emitting film layer 212, a cathode layer 213, and a cathode insulating layer 214, which are stacked in sequence. The anode layer 211 is provided on the substrate 1. The viewing angle switching component 5 is provided between the cathode insulating layer 214 and the encapsulation layer 4. The cathode insulating layer 214 is used to isolate the charged particles in the cathode layer 213 and the viewing angle switching component 5. The light emitted by the light-emitting film layer 212 is controlled by the anode and cathode. The light emitted by the light-emitting film layer 212 is emitted into the corresponding receiving cavity, and then the corresponding viewing angle switching component 5 is used to switch the anti-peeping mode.

[0059] In one embodiment, in order to further isolate the electrical coupling influence between the anode layers 211 of adjacent light-emitting units 21, the display panel also includes an anode insulation layer 6 arranged between the anode layers 211 of each light-emitting unit 21, and the isolation plate 3 is arranged between the anode insulation layer 6 and the encapsulation layer 4.

[0060] Among them, in order to achieve the isolation effect, such as Figure 5 As shown, the thickness of the anode insulating layer 6 is greater than that of the anode layer 211 , and the thickness direction is the stacking direction of the film layers in the light emitting unit 21 .

[0061] In one embodiment, in order to achieve a good encapsulation and sealing effect, an adhesive layer is provided between the substrate 1 and the isolation plate 3, and between the isolation plate 3 and the encapsulation layer 4 for bonding, fixing and sealing. The adhesive layer can be OCA (Optical Clear Adhesive) or the like.

[0062] In one embodiment, in order to facilitate the movement of the charged particles 52 , a dispersion medium is provided in the accommodation chamber. The dispersion medium is a commonly used dispersion medium in the field of electrophoresis (not shown in the figure), which will not be described in detail in this embodiment.

[0063] In one embodiment, in order to avoid holes on the sidewall that do not adsorb the charged particles 52, the two ends of the sidewall electrode 51 are respectively abutted between the packaging layer 4 and the substrate 1, or, as shown in FIG. Figure 5 As shown, both ends of the sidewall electrode 51 are respectively abutted between the packaging layer 4 and the cathode insulating layer 214 .

[0064] In this embodiment, sidewall electrodes 51 and charged particles 52 are added to the accommodating cavity formed by the substrate 1, the isolation plate 3 and the encapsulation layer 4. The charged particles 52 are adsorbed by controlling the electrical properties of the sidewall electrodes 51 to achieve an anti-peeping mode without significantly increasing the thickness of the display panel.
