Description

Technical Field

[0001] The present application relates to the field of display, and in particular to a display panel and an electronic device having the display panel. Background Art

[0002] At present, with the development of science and technology, the functions of electronic devices such as mobile phones are becoming increasingly rich, and people are increasingly relying on electronic devices such as mobile phones in their daily lives. At present, due to various needs, people usually use electronic devices such as mobile phones in crowded places. However, when there are many people around, the content displayed by the electronic devices is often seen by people around, exposing privacy. At present, anti-peep films are launched on the market. By sticking anti-peep films on electronic devices such as mobile phones, people around can be prevented from peeping and achieve the purpose of protecting personal privacy. However, the anti-peep film is based on the principle of blinds polarization, blocking part of the light. For example, the transmittance is low, and it is only about 70% when looking directly at the screen, resulting in a decrease in display brightness under the same luminous brightness of the electronic device. In order to increase the display brightness, the display brightness of the mobile phone itself, that is, the luminous brightness, has to be increased, which leads to an increase in luminous power and deterioration in power consumption. Moreover, the clarity of the anti-peep film is poor, with obvious graininess, which makes the screen font blurred and affects the user's perception. In addition, the anti-peep film is thick, and the fingerprint of the electronic device is easy to fail, resulting in low fingerprint recognition efficiency. It often takes several attempts to successfully recognize, affecting the user's experience of using fingerprint recognition for unlocking and payment. Summary of the invention

[0003] The present application provides a display panel, a display screen and an electronic device to solve the above problems.

[0004] In a first aspect, a display panel is provided, comprising a display layer, the display layer comprising a plurality of pixel units distributed in rows and columns, the plurality of pixel units comprising a plurality of first-type pixel units and a plurality of second-type pixel units; wherein a light exit port of the first-type pixel unit is smaller than a light exit port of the second-type pixel unit, so that a display viewing angle range of the first-type pixel unit is smaller than a display viewing angle range of the second-type pixel unit.

[0005] In a second aspect, a display screen is provided, the display screen comprising a glass cover plate and a display panel. The display panel comprises a display layer, the display layer comprises a plurality of pixel units distributed in rows and columns, the plurality of pixel units comprises a plurality of first-type pixel units and a plurality of second-type pixel units; the light exit port of the first-type pixel unit is smaller than the light exit port of the second-type pixel unit, so that the display viewing angle range of the first-type pixel unit is smaller than the display viewing angle range of the second-type pixel unit.

[0006] In a third aspect, an electronic device is further provided, the electronic device comprising a display screen, the display screen comprising a glass cover plate and a display panel. The display panel comprises a display layer, the display layer comprises a plurality of pixel units distributed in rows and columns, the plurality of pixel units comprise a plurality of first-type pixel units and a plurality of second-type pixel units; the light exit port of the first-type pixel unit is smaller than the light exit port of the second-type pixel unit, so that the display viewing angle range of the first-type pixel unit is smaller than the display viewing angle range of the second-type pixel unit.

[0007] The display panel, display screen and electronic device of the present application include a plurality of first-type pixel units and a plurality of second-type pixel units, and the light outlet of the first-type pixel unit is smaller than the light outlet of the second-type pixel unit. Therefore, since the light outlet of the first-type pixel unit is smaller, the angle of light path divergence will be smaller, so that the display viewing angle range of the first-type pixel unit can be smaller than the display viewing angle range of the second-type pixel unit. Therefore, the display panel can only emit light through the first-type pixel unit with a smaller display viewing angle range when necessary, and since the display viewing angle range of the first-type pixel unit is smaller, a better anti-peeping effect can be achieved.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In the description of the embodiments of the present invention, it should be understood that the terms "upper", "lower", "thickness", "width", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than implying or indicating that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. The term "connection" in this application includes the meanings of physical structural connection, electrical connection, direct connection or indirect connection, and can be determined specifically according to the required connection situation. In the description of the embodiments of the present invention, the terms "first", "second", etc. are not specific, but are used to distinguish objects with the same name. If there is a description in the specification, the objects with the same name referred to by the terms "first", "second", etc. may be the same objects.

[0026] See also Figure 1 , is a cross-sectional schematic diagram illustrating a partial structure of a display panel 100 in an embodiment of the present application. Figure 1 As shown, the display panel 100 includes a display layer 1, and the display layer 1 includes a plurality of pixel units 11 distributed in rows and columns, and the plurality of pixel units 11 include a plurality of first-type pixel units 12 and a plurality of second-type pixel units 13. The light outlet K1 of the first-type pixel unit 12 is smaller than the light outlet K1 of the second-type pixel unit 13, so that the display viewing angle range of the first-type pixel unit 12 is smaller than the display viewing angle range of the second-type pixel unit 13.

[0027] Therefore, the display panel 100 of the present application includes a plurality of first-type pixel units 12 and a plurality of second-type pixel units 13, and the light outlet K1 of the first-type pixel unit 12 is smaller than the light outlet K1 of the second-type pixel unit 13. Therefore, since the light outlet K1 of the first-type pixel unit 12 is smaller, the angle of light path divergence will be smaller, so that the display viewing angle range of the first-type pixel unit 12 can be smaller than the display viewing angle range of the second-type pixel unit 13. Therefore, the display panel 100 can emit light only through the first-type pixel unit 12 with a smaller display viewing angle range when necessary, and since the display viewing angle range of the first-type pixel unit 12 is smaller, a better anti-peeping effect can be achieved.

[0028] In the present application, the display layer 1 includes a plurality of pixel units 11 distributed in rows and columns, and the plurality of pixel units 11 include a plurality of first-type pixel units 12 and a plurality of second-type pixel units 13, so that the plurality of first-type pixel units 12 and the plurality of second-type pixel units 13 are distributed in an array, that is, distributed in various regions of the display layer 1. Therefore, when the display panel 100 is required to emit light only through the first-type pixel units 12, within the display viewing angle range of the first-type pixel units 12, the user can normally view the display content of the display panel 100.

[0029] Among them, in the present application, the display viewing angle range of the first type of pixel unit 12 is smaller than the display viewing angle range of the second type of pixel unit 13, which may mean that the display viewing angle range of the first type of pixel unit 12 is a partial viewing angle range in the display viewing angle range of the second type of pixel unit 13.

[0030] In some embodiments, the light outlets K1 of the plurality of pixel units 11 are also openings of the pixel units 11. Figure 1 As shown, the angle between the display viewing angle within the display viewing angle range of each pixel unit 11 and the normal line L1 direction of the light outlet K1, wherein the display viewing angle within the display viewing angle range of each pixel unit 11 includes a 0° viewing angle.

[0031] That is, in some embodiments, the display viewing angle range of the pixel unit 11, that is, the first type of pixel unit 12 or the second type of pixel unit 13, is an angle range including 0° with the normal line L1 of the surface where the light outlet K1 of the pixel unit 11 is located, that is, a viewing angle range including the viewing angle in the direction of the normal line L1. Figure 1 As shown, the display viewing angle range of the first type pixel unit 12 includes viewing angles within an angle θ1 less than or equal to the normal line L1, and the display viewing angle range of the second type pixel unit 13 includes viewing angles within an angle θ0 less than or equal to the normal line L1.

[0032] Among them, the surface where the light outlet K1 of the pixel unit 11 is located is also the display surface or light outlet surface of the display layer 1. The normal line L1 direction of the light outlet K1 of the pixel unit 11 may also refer to the direction perpendicular to the display surface of the display layer 1 and toward one side of the display surface.

[0033] Among them, Figure 1 As shown in FIG. 1 , since the light outlet K1 of the first type pixel unit 12 is smaller than the light outlet K1 of the second type pixel unit 13, the light outlet surface is smaller, the light beam will be more concentrated, and the light divergence angle of the first type pixel unit 12 will be smaller than that of the second type pixel unit 13. Figure 1As shown, the angle θ1 is smaller than θ0, that is, the display viewing angle range of the first type of pixel unit 12 is smaller than the display viewing angle range of the second type of pixel unit 13 .

[0034] The display viewing angle range of the pixel unit 11 is the visible viewing angle range that can be viewed by the viewer, that is, the visible viewing angle range when the viewer looks directly at the display surface of the display panel 100. When the viewer is located in front of the display panel 100, the sight line direction is parallel to the normal line L1. At this time, the user's viewing angle and display viewing angle are 0°, and the content displayed by the display panel 100 can be clearly viewed by the user. When the user looks at the display panel 100 from the side, the user's viewing angle is the angle between the user's sight line at the position of the pixel unit 11 and the normal line L1. When the user's viewing angle is outside the display viewing angle range of the pixel unit 11, the user's eyes cannot receive the outgoing light emitted by the pixel unit 11, and cannot view the display content at the corresponding pixel unit 11. Therefore, by limiting the display viewing angle range of the first type of pixel unit 12 to a smaller range, and only controlling the first type of pixel unit 12 to emit light and display as needed, it can effectively ensure that the display content of the display panel 100 cannot be viewed from the side at an angle exceeding a certain range, and effectively achieve anti-peeping.

[0035] in, Figure 1 Specifically, it can be a cross-sectional schematic diagram taken along a certain target direction of the display panel 100, and the display viewing angle range of the first type of pixel unit 12 includes Figure 1 The viewing angle range on the left side of the normal line L1 and the viewing angle range on the right side shown in the figure form a roughly symmetrical viewing angle range centered on the normal line L1. Figure 1 As shown, the display viewing angle range of the first type of pixel unit 12 includes a viewing angle range of 0° to θ1. The 0° viewing angle coincides with the direction of the normal L1, and the display viewing angle range on one side of the target direction is 0°~θ1, and the display viewing angle range on the other side of the target direction is also 0°~θ1, that is, the display viewing angle ranges on both sides of the target direction are the same. In some embodiments, the display viewing angle range of the first type of pixel unit 12 on one side of the target direction may be different from the display viewing angle range on the other side of the target direction. In some embodiments, the display viewing angle range of the first type of pixel unit 12 includes a viewing angle range of 0° to θ0, wherein the display viewing angle range of the second type of pixel unit 13 on one side of the target direction may be the same as or different from the display viewing angle range on the other side of the target direction.

[0036] See also Figure 2, is a schematic plan view of the display layer 1 of the display panel 100 in some embodiments of the present application. In some embodiments, the plurality of pixel units 11 constitute a plurality of repeating units 10, that is, the plurality of first-type pixel units 12 and the plurality of second-type pixel units 13 constitute a plurality of repeating units 10. Figure 2 As shown, the multiple repeating units 10 are distributed in rows and columns, and each repeating unit 10 includes at least one first type pixel unit 12 and at least one second type pixel unit 13, and the at least one first type pixel unit 12 and at least one second type pixel unit 13 in each repeating unit 10 are arranged along the row direction.

[0037] That is, in some embodiments, the display layer 1 may include a plurality of repeating units 10, each repeating unit 10 includes at least one first-type pixel unit 12 and at least one second-type pixel unit 13, and the at least one first-type pixel unit 12 and at least one second-type pixel unit 13 in each repeating unit 10 are arranged along a row direction. Thus, in this way, it is convenient to manufacture and form the display layer 1.

[0038] In some embodiments, each first-type pixel unit 12 includes three first-type sub-pixel units 121, and each second-type pixel unit 13 includes three second-type sub-pixel units 131. Figure 2 As shown, the three first-type sub-pixel units 121 are arranged along the column direction, and the three second-type sub-pixel units 131 are also arranged along the column direction.

[0039] That is, in some embodiments, three first-type sub-pixel units 121 in the same first-type pixel unit 12 are arranged along the column direction, and three second-type sub-pixel units 131 in the same second-type pixel unit 13 are also arranged along the column direction.

[0040] Thus, through the above arrangement, Figure 2 As shown, in the same column of the display panel 100, all are the first type of sub-pixel units 121, or all are the second type of sub-pixel units 131. In the same row of the display panel 100, the first type of sub-pixel units 121 and the second type of sub-pixel units 131 are arranged in a mixed manner. Therefore, when only the first type of pixel unit 12 emits light for display, a good anti-peeping effect along the row direction can be achieved, and when at least the second type of sub-pixel unit 131 emits light for display, a good display effect can be achieved.

[0041] In some embodiments, Figure 2As shown, the three first-type sub-pixel units 121 include a first-type R pixel unit 121a, a first-type G pixel unit 121b, and a first-type B pixel unit 121c, and the three second-type sub-pixel units 131 include a second-type R pixel unit 131a, a second-type G pixel unit 131b, and a second-type B pixel unit 131c. In some embodiments, Figure 2 As shown, the first type R pixel unit 121a, the first type G pixel unit 121b and the first type B pixel unit 121c in each first type pixel unit 12 are arranged sequentially along the column direction, and the second type B pixel unit 131b, the second type R pixel unit 131a, and the second type G pixel unit 131c in each second type pixel unit 13 are arranged sequentially along the column direction.

[0042] That is, in some embodiments, the three sub-pixel units in each first-type pixel unit 12 are arranged along the column direction, and specifically the first-type R pixel unit 121a, the first-type G pixel unit 121b, and the first-type B pixel unit 121c are arranged in sequence along the column direction, and the three sub-pixel units in each second-type pixel unit 13 are also arranged along the column direction, and specifically the second-type B pixel unit 131b, the second-type R pixel unit 131a, and the second-type G pixel unit 131c are arranged in sequence along the column direction.

[0043] Therefore, this method is helpful to improve the display effect when the first type pixel unit 12 and the second type pixel unit 13 emit light and display at the same time.

[0044] in, Figure 2 In the example, each repeating unit 10 includes a first type pixel unit 12 and a second type pixel unit 13, and the first type pixel units and the second type pixel units in each repeating unit 10 are alternately arranged along the row direction. Figure 2 The pixel arrangement shown adopts 2 / 3SPR sub-pixel rendering technology to achieve a display effect of three pixels by two pixel units 11 in the row direction through the SPR algorithm, which can effectively improve the overall pixel aperture ratio.

[0045] Obviously, in some embodiments, each repeating unit 10 may also include other numbers of first-type pixel units 12 and second-type pixel units 13. For example, each repeating unit 10 may also include two first-type pixel units 12 and one second-type pixel unit 13, and along the row direction, the second-type pixel unit 13 in each repeating unit 10 is located between two first-type pixel units 12. For another example, each repeating unit 10 may also include one first-type pixel unit 12 and two second-type pixel units 13, and along the row direction, the first-type pixel unit 12 in each repeating unit 10 is located between two second-type pixel units 13, and so on.

[0046] in, Figure 2 The above example is only an example, and the first type of pixel unit 12 and the second type of pixel unit 13 and the sub-pixel units included therein may also have other arrangements, as long as it can be achieved that when only the first type of pixel unit 12 emits light for display, anti-peeping in certain directions can be achieved, and normal viewing within the display viewing angle range can be achieved. For example, in some embodiments, the at least one first type of pixel unit 12 and the at least one second type of pixel unit 13 in each repeating unit 10 are arranged along the column direction, and each first type of pixel unit 12 includes three first type of sub-pixel units 121, and each second type of pixel unit 13 includes three second type of sub-pixel units 131, and the three first type of sub-pixel units 121 are arranged along the row direction, and the three second type of sub-pixel units 131 are also arranged along the row direction.

[0047] See also Figure 3 , is another plan view schematically showing the display layer 1 of the display panel 100 in some embodiments of the present application.

[0048] In some embodiments, the plurality of pixel units 11 on the display layer 1 may not constitute a repeated unit, and the plurality of first-type pixel units 12 and second-type pixel units 13 may be arbitrarily arranged in rows and columns, as long as the first-type pixel units 12 and second-type pixel units 13 that meet the display requirements are distributed in each region of the display layer 1. That is, as long as it is satisfied that when only the first-type pixel unit 12 emits light for display, a complete and clear display content can be viewed within the display viewing angle range of the first-type pixel unit 12, and when at least the second-type pixel unit 13 emits light for display, a complete and clear display content can be viewed within the corresponding display viewing angle range.

[0049] For example, Figure 3 As shown, in each row of the display layer 1 , a plurality of first-type pixel units 12 and a plurality of second-type pixel units 13 are interspersed, and the arrangement of the plurality of first-type pixel units 12 and the plurality of second-type pixel units 13 in different rows may be different.

[0050] As mentioned above, the three first-type sub-pixel units 121 include a first-type R pixel unit 121a, a first-type G pixel unit 121b, and a first-type B pixel unit 121c, and the three second-type sub-pixel units 131 include a second-type R pixel unit 131a, a second-type G pixel unit 131b, and a second-type B pixel unit 131c. That is, each first-type pixel unit 12 includes a first-type R pixel unit 121a, a first-type G pixel unit 121b, and a first-type B pixel unit 121c, and each second-type pixel unit 13 includes a second-type R pixel unit 131a, a second-type G pixel unit 131b, and a second-type B pixel unit 131c. In some embodiments, the light exit port K1 of the first type pixel unit 12 is smaller than the light exit port K1 of the second type pixel unit 13, which may mean that the light exit port K1 of the first type R pixel unit 121a is smaller than the light exit port K1 of the second type R pixel unit 131a, the light exit port K1 of the first type G pixel unit 121b is smaller than the light exit port K1 of the second type G pixel unit 131b, and the light exit port K1 of the first type B pixel unit 121c is smaller than the light exit port K1 of the second type B pixel unit 131c.

[0051] That is, in some embodiments, the light exit port K1 of the first type of pixel unit 12 is smaller than the light exit port K1 of the second type of pixel unit 13, which may refer to the display viewing angle range in which the light exit port K1 of the first type of sub-pixel unit 121 of a certain color is smaller than the light exit port K1 of the second type of sub-pixel unit 131 of the corresponding color. In some embodiments, the light exit port K1 of the first type of pixel unit 12 is smaller than the light exit port K1 of the second type of pixel unit 13, which may refer to the light exit port K1 of all the first type of sub-pixel units 121 of the first type of pixel unit 12 is smaller than the light exit port K1 of any second type of sub-pixel unit 131 of the second type of pixel unit 13. In the present application, the display viewing angle range in which the light exit port K1 of the first type of sub-pixel unit 121 of a certain color is smaller than the light exit port K1 of the second type of sub-pixel unit 131 of the corresponding color is mainly described as an example.

[0052] In some embodiments, the size of the light exit K1 of the first-type R pixel unit 121a along at least the row direction is smaller than the size of the light exit K1 of the second-type R pixel unit 131a along the row direction, the size of the light exit K1 of the first-type G pixel unit 121b along at least the row direction is smaller than the size of the light exit K1 of the second-type G pixel unit 131b along the row direction, and the size of the light exit K1 of the first-type B pixel unit 121c along at least the row direction is smaller than the size of the light exit K1 of the second-type B pixel unit 131c along the row direction.

[0053] That is, in some embodiments, the light outlet K1 of the first type of pixel unit 12 is smaller than the light outlet K1 of the second type of pixel unit 13, and at least the size of the light outlet K1 of the first type of pixel unit 12 in the row direction may be smaller than the size of the light outlet K1 of the first type of pixel unit 12 in the row direction. Therefore, since at least the size of the light outlet K1 of the first type of pixel unit 12 in the row direction is smaller than the size of the light outlet K1 of the first type of pixel unit 12 in the row direction, the display viewing angle range of the first type of pixel unit 12 in at least the row direction is smaller than the display viewing angle range of the second type of pixel unit 13 in the row direction.

[0054] In some embodiments, the size of the light exit K1 of the first-type R pixel unit 121a along the column direction may be smaller than or equal to the size of the light exit K1 of the second-type R pixel unit 131a along the column direction, the size of the light exit K1 of the first-type G pixel unit 121b along the column direction may be smaller than or equal to the size of the light exit K1 of the second-type G pixel unit 131b along the row direction, and the size of the light exit K1 of the first-type B pixel unit 121c along the column direction may be smaller than or equal to the size of the light exit K1 of the second-type B pixel unit 131c along the row direction.

[0055] In some embodiments, Figure 1 Specifically, it can be a cross-sectional schematic diagram taken along the row direction of the display panel 100, and as mentioned above, Figure 1 FIG. 2 schematically shows two adjacent pixel units 13, the first type pixel unit 12 and the second type pixel unit 13. Figure 1 As shown, and as mentioned above, the display viewing angle range of the first type of pixel unit 12 includes Figure 1 and Figure 2 The viewing angles on the left and right of the normal line L1 shown in the figure form a roughly symmetrical viewing angle range centered on the normal line L1.

[0056] Among them, the row direction in this application refers to the arrangement direction of each row of pixel units 11 in the multiple row-column distributed pixel units 11, and the column direction in this application refers to the arrangement direction of each column of pixel units 11 in the multiple row-column distributed pixel units 11.

[0057] In some embodiments, when the display panel 100 is used in an electronic device such as a mobile phone, the row direction of the display panel 100 can be the normal holding state of the electronic device such as a mobile phone, such as the left and right direction when the user holds it with one hand and normally views the electronic device, and the column direction can be the normal holding state of the electronic device such as a mobile phone, such as the up and down direction when the user holds it with one hand and normally views the electronic device, that is, the direction perpendicular to the left and right direction.

[0058] In some embodiments, the row direction may also be the left-right direction of the display content when the display panel 100 displays the corresponding display content and the display content is displayed upright. That is, the row direction may not depend on the holding state of the electronic device, but may be the left-right direction of the display content / display screen when it is upright in any holding state.

[0059] Therefore, in some embodiments, the display viewing angle within the aforementioned display viewing angle range includes viewing angles along the row direction on both sides of the normal line L1. Since the light outlet K1 of the first type of pixel unit 12 is smaller in the row direction, the display viewing angle range of the first type of pixel unit 12 is smaller at least in the row direction, and peeping protection can be performed on the left and right sides, and the user can normally watch the display content of the display panel 100 within the display viewing angle range of the first type of pixel unit 12.

[0060] In some embodiments, the size of the light exit K1 of the first type R pixel unit 121a along the column direction is equal to the size of the light exit K1 of the second type R pixel unit along the row direction, the size of the light exit K1 of the first type G pixel unit along the column-row direction is equal to the size of the light exit K1 of the second type G pixel unit along the row direction, and the size of the light exit K1 of the first type B pixel unit along the column direction is equal to the size of the light exit K1 of the second type B pixel unit along the row direction.

[0061] That is, in some embodiments, the light exit K1 of the first type of pixel unit 12 is smaller than the light exit K1 of the second type of pixel unit 13, which may also mean that the size of the exit light K1 of the first type of sub-pixel unit 121 of the first type of pixel unit 12 in the row direction is smaller than the size of the exit light K1 of the second type of sub-pixel unit 131 of the second type of pixel unit 13 in the row direction, while the sizes of the two in the column direction may be the same.

[0062] Therefore, in some embodiments, the display viewing angle range of the first type of pixel unit 12 in the row direction is smaller, and the display viewing angle range of the aforementioned first type of pixel unit 12 is smaller than the display viewing angle range of the second type of pixel unit 13, and the display viewing angle range may at least include the display viewing angle range in the row direction.

[0063] In some embodiments, the size of the light exit port of the first type R pixel unit along the column direction may be smaller than the size of the light exit port of the second type R pixel unit along the row direction, the size of the light exit port of the first type G pixel unit along the column-row direction may be smaller than the size of the light exit port of the second type G pixel unit along the row direction, and the size of the light exit port of the first type B pixel unit along the column direction may be smaller than the size of the light exit port of the second type B pixel unit along the row direction.

[0064] Therefore, in some embodiments, the light exit K1 of the first type of pixel unit 12 is smaller than the light exit K1 of the second type of pixel unit 13, which may also mean that the sizes of the exit light K1 of the first type of sub-pixel unit 121 of the first type of pixel unit 12 in the row direction and the column direction are smaller than the sizes of the exit light K1 of the second type of sub-pixel unit 131 of the second type of pixel unit 13 in the row direction and the column direction.

[0065] Therefore, in some embodiments, the display viewing angle range of the first type of pixel unit 12 in the row direction and the column direction is smaller, and the display viewing angle range of the aforementioned first type of pixel unit 12 is smaller than the display viewing angle range of the second type of pixel unit 13, and the display viewing angle range may include the display viewing angle range in the row direction and the column direction.

[0066] Among them, when the display viewing angle range also includes the display viewing angle range in the column direction, that is, when the display viewing angle within the aforementioned display viewing angle range further includes the viewing angles along the column direction on both sides of the normal direction, the display viewing angle range of the first type of pixel unit 12 can be further limited in the column direction, and anti-peeping can be performed on the upper and lower sides, and the user can normally watch the display content of the display panel 100 within the display viewing angle ranges on the upper, lower and right sides.

[0067] In some embodiments, the size of the light outlet K1 of the second type pixel unit 13 along the row direction is 2 to 4 times the size of the light outlet K1 of the first type pixel unit 12 along the row direction.

[0068] That is, in some embodiments, the size of the light outlet K1 of the first sub-pixel unit 121 of the first type of pixel unit 12 in the row direction is smaller than the size of the light outlet K1 of the second sub-pixel unit 131 of the second type of pixel unit 13 in the row direction, that is, the size of the light outlet K1 of the second type of pixel unit 13 at least along the row direction is larger than the size of the light outlet K1 of the first type of pixel unit 12 along the row direction, and can be 2 to 4 times the size of the light outlet K1 of the first type of pixel unit 12 along the row direction. For example, it can be 2 times, 2.5 times, 3 times, 4 times, and so on.

[0069] In this application, "A" to "B" generally refers to a range greater than or equal to "A" and less than or equal to "B".

[0070] In some embodiments, when the sizes of the exit light K1 of the first type sub-pixel unit 121 of the first type pixel unit 12 in the row direction and the column direction are smaller than the sizes of the exit light K1 of the second type sub-pixel unit 131 of the second type pixel unit 13 in the row direction and the column direction, the size of the light exit K1 of the second type pixel unit 13 along the column direction may also be 2 to 4 times the size of the light exit K1 of the first type pixel unit 12 along the column direction.

[0071] In the present application, the size of the light outlet K1 of the second type pixel unit 13 may be the same as the size of the light outlet K1 of the current normal pixel unit, that is, the light outlet K1 of the second type R pixel unit 131a, the light outlet K1 of the second type G pixel unit 131b, and the light outlet K1 of the second type B pixel unit 131c may be the same as the size of the light outlets of the current normal R pixel unit, G pixel unit, and B pixel unit. Therefore, the light outlet K1 of the first type pixel unit 12 is smaller than the size of the light outlet K1 of the second type pixel unit 13, that is, smaller than the size of the light outlet K1 of the current normal pixel unit.

[0072] In some embodiments, the size of the light outlet K1 of the second type of pixel unit 13 may also be larger than the size of the light outlet K1 of the current normal pixel unit, while the light outlet K1 of the first type of pixel unit 12 is smaller than the size of the light outlet K1 of the second type of pixel unit 13, and smaller than the size of the light outlet K1 of the current normal pixel unit. For example, as mentioned above, the size of the light outlet K1 of the second type of pixel unit 13 along a certain direction may be 2 to 4 times the size of the first type of pixel unit 12 along the direction, and the difference is quite obvious. Therefore, one size of the light outlet K1 of the second type of pixel unit 13 may be larger than the size of the light outlet K1 of the normal pixel unit, and the other size of the light outlet K1 of the normal pixel unit may be smaller.

[0073] In some embodiments, the size of the light outlet K1 of the second type of pixel unit 13 along the row direction may be 1.5 to 2 times the size of the light outlet K1 of the current normal pixel unit, and the size of the light outlet K1 of the first type of pixel unit 12 along the row direction may be 1 / 2 times the size of the light outlet K1 of the current normal pixel unit, etc. Therefore, the size of the first type of pixel unit 12 at least in the row direction may be significantly smaller than the size of the light outlet K1 of the current normal pixel unit, thereby realizing anti-peeping in the row direction, that is, in the left and right directions. In some embodiments, the size of the light outlet K1 of the first type of pixel unit 12 and the second type of pixel unit 13 along the column direction may be 1.5 to 2 times the size of the light outlet K1 of the current normal pixel unit, that is, because in the column direction, if viewed by other people around, the display content is inverted, it is generally not easy to see clearly. Therefore, anti-peeping in the row direction, that is, anti-peeping in the left and right directions, can be mainly realized. By increasing the size of the light outlet K1 of the first type pixel unit 12 and the second type pixel unit 13 along the column direction, the display brightness can be effectively increased and the display effect can be improved when at least the second type pixel unit 13 is controlled to emit light in a normal display mode without privacy protection.

[0074] In the present application, as mentioned above, the size of the light exit port K1 of the pixel unit 11 specifically refers to the size of the light exit port K1 of the sub-pixel unit included in the pixel unit 11, that is, the size of the light exit port K1 of the first-type pixel unit 12 is specifically the size of the light exit port K1 of the first-type sub-pixel unit 121 included in the first-type pixel unit 12, and the size of the light exit port K1 of the second-type pixel unit 13 is specifically the size of the light exit port K1 of the second-type sub-pixel unit 131 included in the second-type pixel unit 13.

[0075] In some embodiments, the size of the light outlet K1 of the pixel unit 11 may refer to the size of the light outlet K1 of the pixel unit 11 along certain directions, that is, specifically refers to the size of the light outlet K1 of the sub-pixel unit included in the pixel unit 11 along certain directions. In some embodiments, the size of the light outlet K1 of the pixel unit 11 may also refer to the area of ​​the light outlet K1 of the pixel unit 11, that is, specifically refers to the area of ​​the light outlet K1 of the sub-pixel unit included in the pixel unit 11.

[0076] In some embodiments, the size of the exit light K1 of the first type of sub-pixel unit 121 of the first type of pixel unit 12 is less than or equal to 15 μm (micrometers) at least in the row direction. In some embodiments, the size of the exit light K1 of the first type of sub-pixel unit 121 of the first type of pixel unit 12 is less than 5 μm at least in the row direction.

[0077] See also Figure 4 , is a curve diagram showing the relationship between viewing angle and display brightness obtained by simulation test using the pixel unit 11 with light outlets K1 of different sizes as an example.

[0078] in, Figure 4 , respectively, curves S11, S12, and S13 showing the relationship between the display viewing angle and the display brightness in the simulation test when the light outlet K1 is 5 μm, 10 μm, and 15 μm. Figure 4 The viewing angle in the figure may be a viewing angle. As mentioned above, the viewing angle may be the angle between the line of sight and the normal line L1 of the pixel unit 11, which is also equivalent to the display viewing angle corresponding to the display panel 100.

[0079] from Figure 4 It can be seen that the smaller the light outlet K1 is, the greater the viewing angle is, the more the brightness decays, and when the decay reaches a certain level, it is equivalent to being invisible, indicating that the light emitted by the display panel 100 under the viewing angle / display angle is basically invisible. Therefore, the smaller the light outlet K1 is, the smaller the display angle range of the pixel unit, that is, the visible angle range, is, the smaller the anti-peeping effect is.

[0080] For example, Figure 4 The size of the light outlet K1 of the pixel unit 11 may be the size along the row direction, and the viewing angle may be the angle between the light outlet K1 and the normal line L1 when viewed from the row direction.

[0081] And from Figure 4 It can be seen that when the pixel unit 11 is 15 μm, the brightness at a temperature greater than 30° can be attenuated to 50%, and a certain anti-peeping effect can be achieved. Therefore, in some embodiments, the size of the exit light K1 of the first type of sub-pixel unit 121 of the first type of pixel unit 12 at least in the row direction is less than or equal to 15 μm (micrometer).

[0082] Please return to Figure 2 ,in, Figure 2 In the embodiment, it is illustrated by taking as an example that each repeating unit 10 includes a first type pixel unit 12 and a second type pixel unit 13, and the first type pixel units 12 and the second type pixel units 13 in each repeating unit 10 are alternately arranged along the row direction.

[0083] In some embodiments, as described above, each repeating unit 10 includes a first type pixel unit 12 and a second type pixel unit 13, and the first type pixel units 12 and the second type pixel units 13 in each repeating unit 10 are alternately arranged along the row direction. Obviously, in some embodiments, as described above, each repeating unit 10 may also include other numbers of first type pixel units 12 and second type pixel units 13.

[0084] See also Figure 5 , is a schematic diagram of the stacking of a partial structure of the display panel 100 in some embodiments of the present application.

[0085] like Figure 5 As shown, in some embodiments, the display panel 100 further includes a black matrix layer 3. The black matrix layer 3 is stacked on the light-emitting surface of the display layer 1, wherein the light-emitting surface is the surface provided with the light outlet K1, and the black matrix layer 3 is used to block part of the light-emitting path of the first-type pixel unit 12, thereby further limiting the display viewing angle range of the first-type pixel unit 12.

[0086] That is, in some embodiments, although the light outlet K1 of the first type of pixel unit 12 is small, the light divergence angle can be small, and therefore, the display viewing angle range of the first type of pixel unit 12 is small, and a better anti-peeping effect can be achieved. However, the brightness at some display viewing angles is not particularly low, so the anti-peeping effect is not particularly good. Therefore, the display panel 100 of the present application further limits the display viewing angle range of the first type of pixel unit 12 through the black matrix layer 3, and can effectively improve the anti-peeping effect.

[0087] In some embodiments, the black matrix layer 3 includes a plurality of black matrix frames 31, each black matrix frame 31 corresponds to a first type pixel unit 12, and the projection on the display layer 1 at least partially surrounds the corresponding first type pixel unit 12, and the black matrix frame 31 is used to block part of the light emitting path of the first type pixel unit 12, thereby further limiting the display viewing angle range of the first type pixel unit 12.

[0088] That is, in some embodiments, the black matrix layer 3 includes a plurality of black matrix frames 31, each black matrix frame 31 corresponds to a first-type pixel unit 12, and the projection on the display layer 1 at least partially surrounds the corresponding first-type pixel unit 12, and a portion of the light output path of the first-type pixel unit 12 is blocked, thereby further limiting the display viewing angle range of the first-type pixel unit 12, and can effectively improve the anti-peeping effect.

[0089] In some embodiments, the black matrix layer 3 may also be provided with a plurality of through holes, each of which is provided corresponding to each first-type pixel unit 12, and part of the light of the first-type pixel unit 12 is transmitted through the corresponding through hole. That is, in some embodiments, the black matrix layer 3 may also be a whole black shielding layer, and the black matrix layer 3 may be provided with a plurality of through holes, each of which is provided corresponding to each first-type pixel unit 12, and part of the light of the first-type pixel unit 12 is transmitted through the corresponding through hole. The area surrounding the through hole on the black matrix layer 3 may block part of the light exit path of the first-type pixel unit 12, and further limit the display viewing angle range of the first-type pixel unit 12. In some implementations, in the structure in which the black matrix layer 3 is provided with a plurality of through holes, it may also be understood to include the black matrix frame 31. In this case, the plurality of black matrix frames 31 may be frames formed by the area of ​​the black matrix layer 3 surrounding the through hole.

[0090] Among them, in this application, the black matrix layer 3 is mainly used to include multiple black matrix frames 31, and in some embodiments, the black matrix layer 3 may only include a black matrix frame 31 whose projection on the display layer 1 at least partially surrounds the corresponding first type pixel unit 12.

[0091] Among them, in the present application, the "A" layer is stacked on the "B" layer, including that the "A" layer is in direct contact with the "B" layer, and is directly stacked on the "B" layer, and also includes that a "C" layer is further arranged between the "A" layer and the "B" layer, and can be indirectly stacked on the "B" layer through the "C" layer. Among them, above or on a certain layer in the present application refers to the side of the layer facing the light emitting surface of the display panel 100. Among them, in the present application, the areas of the layers of the display panel 100 are roughly the same, that is, the projections of the layers of the display panel 100 along the stacking direction roughly overlap, so as to form a display panel 100 with a multi-layer structure.

[0092] In some embodiments, Figure 5 As shown, as mentioned above, when there is no black matrix frame 31, the display viewing angle range of the first type pixel unit 12 includes a viewing angle range of 0° to θ1, and the display viewing angle range of the second type pixel unit 13 includes a viewing angle range of 0° to θ0. Among them, the 0° viewing angle coincides with the direction of the normal line L1. Among them, as Figure 5As shown, when the black matrix layer 3 includes a plurality of black matrix frames 31, each black matrix frame 31 corresponds to a first type pixel unit 12, and the projection on the display layer 1 at least partially surrounds the corresponding first type pixel unit 12, the black matrix frame 31 is used to block part of the light emitting path of the first type pixel unit 12, and cover the preset viewing angle range of the first type pixel unit 12, so that the display viewing angle range of the first type pixel unit 12 is further limited to the viewing angle range of 0 to θ2, wherein θ2 is smaller than θ1.

[0093] The preset viewing angle interval is an interval ranging from a viewing angle greater than 0° to another viewing angle at least greater than θ1.

[0094] in, Figure 5 FIG. 3 shows a frame edge 310 of the black matrix frame 31. Figure 5 As shown, each frame edge 310 of the black matrix frame 31 includes a first end 31a close to the normal L1 of the first type pixel unit 12 and a second end 31b away from the normal L1, wherein the width of the frame edge 310 of the black matrix frame 31, that is, the distance between the first end 31a and the second end 31b of the frame edge 310 of the black matrix frame 31 satisfies so that the angle θ3 between the first end 31a and the line L11 between the light outlet K1 and the second end 31b and the line L12 between the light outlet K1 is the angle range covered by the preset viewing angle interval.

[0095] The width of the black matrix frame 31, that is, the distance between the first end 31a and the second end 31b of the frame edge 310 of the black matrix frame 31 is not limited, as long as it can cover the corresponding preset viewing angle range.

[0096] In some embodiments, Figure 5 As shown, after part of the light emitting path of the first type pixel unit 12 is blocked by the black matrix frame 31 and the preset viewing angle range of the first type pixel unit 12 is covered, the display viewing angle range of the first type pixel unit 12 is 0~θ2, and specifically is the angle range covered by the angle from the normal L1 to the line L11 connecting the first end 31a and the light outlet K1.

[0097] In some embodiments, the angle θ2 may be a value between 25° and 35°.

[0098] Among them, the aforementioned Figure 2 In the figure, the black matrix frame 31 is also illustrated, and an example is given in which the projection of the black matrix frame 31 on the display layer 1 completely surrounds the corresponding first-type pixel unit 12.

[0099] See also Figure 6 , is a plan view schematic diagram of the black matrix layer 3 of the display panel 100 in some embodiments of the present application.

[0100] in, Figure 6 , which is a schematic top view of the black matrix layer 3 viewed from the side away from the display layer 1. Figure 6 In the figure, the first type of pixel unit 12 and the second type of pixel unit 13 are also indicated in the form of dotted lines.

[0101] like Figure 6 As shown, in some embodiments, the black matrix frame 31 is provided only at the position corresponding to the first type of pixel unit 12 , that is, the projection of each black matrix frame 31 of the black matrix layer 3 on the display layer 1 only surrounds the corresponding first type of pixel unit 12 .

[0102] Among them, Figure 6 As shown, since there will be an arrangement structure in which the first type of pixel unit 12 is adjacent to the second type of pixel unit 13, although the projection of each black matrix frame 31 of the black matrix layer 3 on the display layer 1 only surrounds the corresponding first type of pixel unit 12, the projection of part of the frame edge 310 of the black matrix frame 31 on the display layer 1 will be located between the first type of pixel unit 12 and the second type of pixel unit 13, and will also be close to the second type of pixel unit 13 to a certain extent. Therefore, in the present application, the width of the frame edge 310 of the black matrix frame 31 can be smaller, and the black matrix frame 31 can be as close to the first type of pixel unit 12 as possible. Therefore, when the pixel unit 11 adjacent to the first type of pixel unit 12 is the second type of pixel unit 13, the second type of pixel unit 13 will be less blocked by the black matrix frame 31, which is conducive to improving the display viewing angle range of the second type of pixel unit 13. Due to the cooperation of the metal wiring 21 of the touch layer 2, even if the width of the frame edge 310 of the black matrix frame 31 becomes smaller, it can ensure that a wider viewing angle range is covered, thereby achieving an anti-peeping effect.

[0103] Therefore, if Figure 5 As shown, the outgoing light L3 of the second-type pixel unit 13 will be less blocked, and the display viewing angle range of the second-type pixel unit 13 will be larger. Therefore, when there is no need for privacy protection, at least the second-type pixel unit 13 can be controlled to emit light, that is, the second-type pixel unit 13 can be controlled to emit light, or the second-type pixel unit 13 and the first-type pixel unit 13 can be controlled to emit light at the same time, so as to meet a better display effect.

[0104] Please also read Figure 7 , is a further planar schematic diagram of the black matrix layer 3 of the display panel 100 in some embodiments of the present application.

[0105] In some embodiments, as described above, each first-type pixel unit 12 includes three first-type sub-pixel units 121. Figure 7 As shown, each black matrix frame 31 includes at least one black matrix sub-frame 311, each black matrix sub-frame 311 corresponds to one of the first-type sub-pixel units 121 in the corresponding first-type pixel unit 12, and the projection on the display layer 1 at least partially surrounds the corresponding first-type sub-pixel unit 121.

[0106] That is, in some embodiments, each pixel unit 11 may include three sub-pixel units, for example, the first-type pixel unit 12 includes three first-type sub-pixel units 121, and each black matrix frame 31 includes at least one black matrix sub-frame 311, each black matrix sub-frame 311 corresponds to one of the first-type sub-pixel units 121 in the corresponding first-type pixel unit 12, and the projection on the display layer 1 surrounds the corresponding first-type sub-pixel unit 121.

[0107] In some embodiments, Figure 7 As shown, each black matrix frame 31 includes three black matrix sub-frames 311, each black matrix sub-frame 311 corresponds to a first-type sub-pixel unit 121, and the projection on the display layer 1 surrounds the corresponding first-type sub-pixel unit 121, so that part of the light emitting path of each first-type sub-pixel unit 121 can be blocked.

[0108] Therefore, in some embodiments, each black matrix frame 31 also includes three black matrix sub-frames 311, each black matrix sub-frame 311 corresponds to a first-type sub-pixel unit 121, and the projection on the display layer 1 surrounds the corresponding first-type sub-pixel unit 121, so that the light output path of each first-type sub-pixel unit 121 can be blocked to a certain extent, and the display viewing angle range of each first-type sub-pixel unit 121 can be limited, thereby achieving the limitation of the display viewing angle range of the first-type pixel unit 12.

[0109] In some embodiments, each pixel unit 11 may include three sub-pixel units. For example, the first-type pixel unit 12 includes three first-type sub-pixel units 121, wherein the first-type sub-pixel unit 121 is the smallest pixel unit, and the three first-type sub-pixel units 121 correspond to the three primary colors of red, green, and blue. By controlling the light emission of different combinations of the three first-type sub-pixel units 121 and / or controlling the light emission brightness of the currently emitting first-type sub-pixel units 121, different colors can be mixed, so that the first-type pixel unit 12 can present the corresponding color, that is, emit light of the corresponding color.

[0110] In the present application, the pixel unit 12 may also be a light-emitting unit, and the three sub-pixel units, such as the first sub-pixel unit 121, may be three light-emitting elements for emitting light of different colors, such as three OLEDs (Organic Light-Emitting Diodes), etc. By controlling the light-emitting elements of different combinations in the pixel unit 12 to emit light and / or controlling the light-emitting brightness of the currently emitting light-emitting elements, different colors can be mixed, so that the pixel unit 11 can present the corresponding color, that is, emit light of the corresponding color.

[0111] See also Figure 8 , is another further plan schematic diagram of the black matrix layer 3 of the display panel 100 in some embodiments of the present application.

[0112] In some embodiments, as described above, Figure 8 As shown, the three first-type sub-pixel units 121 include a first-type R (Red) pixel unit 121a, a first-type G (Green) pixel unit 121b and a first-type B (Blue) pixel unit 121c, and at least the first-type G pixel unit 121b corresponds to a black matrix sub-frame 311.

[0113] That is, in some embodiments, at least one black matrix sub-frame 311 included in each black matrix frame 31 includes at least a black matrix sub-frame 311 corresponding to the first type G pixel unit 121b, and the projection on the display layer 1 surrounds the corresponding first type G pixel unit 121b.

[0114] Among them, for a display panel 100, generally speaking, the number of green sub-pixel units, that is, G pixel units, is the largest, and generally speaking, the size of the green sub-pixel units, that is, G pixel units, is also larger. Therefore, limiting the display viewing angle range of the first type of pixel unit 12 can also be at least limiting the first type of G pixel unit 121b. When the display viewing angle range of the first type of G pixel unit 121b is limited, when viewing from within the display viewing angle range, more positions cannot be viewed, resulting in missing or unclear display content, and the purpose of anti-peeping can also be achieved.

[0115] in, Figure 8 In the figure, it is illustrated by taking as an example that only the first-type G pixel unit 121b corresponds to a black matrix sub-frame 311, and each black matrix frame 31 only includes a black matrix sub-frame 311 corresponding to the first-type G pixel unit 121b.

[0116] In some embodiments, the first type G pixel unit 121b and the first type R pixel unit 121a may have a corresponding black matrix sub-frame 311, or the first type G pixel unit 121b and the first type B pixel unit 121c may have a corresponding black matrix sub-frame 311. Figure 7 As shown, the first type R pixel unit 121 a , the first type G pixel unit 121 b , and the first type B pixel unit 121 c all correspond to a black matrix sub-frame 311 .

[0117] In some embodiments, as discussed above, the size of the light outlet K1 of the first type of pixel unit 12 along at least the row direction is smaller than the size of the light outlet K of the second type of pixel unit 13 along the row direction, and the projection of each black matrix frame 31 on the display layer 1 is at least located on two opposite sides of the corresponding first type of pixel unit 12 along the row direction.

[0118] That is, in some embodiments, the size of the light outlet K1 of the first type of pixel unit 12 at least along the row direction is smaller than the size of the light outlet K of the second type of pixel unit 13 along the row direction, and the size of the light outlet K1 of the first type of pixel unit 12 along the column direction may be smaller than or equal to the size of the light outlet K of the second type of pixel unit 13 along the column direction. Thus, at least in the row direction, the black matrix frame 31 can be used to cover part of the viewing angle interval, and the display viewing angle range of the first type of pixel unit 12 in the row direction is further limited, thereby improving the left and right anti-peeping effect.

[0119] Obviously, in some embodiments, Figure 7 and Figure 8 As shown in the above figures, the projection of each black matrix sub-frame 311 on the display layer 1 completely surrounds the corresponding first-type pixel unit 12 .

[0120] That is, in some embodiments, in the column direction, part of the viewing angle interval can be covered by cooperating with the black matrix frame 31, and the display viewing angle range of the first type of pixel unit 12 in the column direction can be further limited to improve the top and bottom anti-peeping effect.

[0121] Please return to Figure 5In some embodiments, as mentioned above, the display viewing angle range of the first type of pixel unit 12 is a viewing angle range of 0 to θ2, and specifically, the angle range covered by the angle between the normal line L1 and the line L11 between the first end 31a and the light outlet K1. Generally speaking, the vertical distance between the black matrix frame 31 and the light outlet K1 of the first type of pixel unit 12, that is, the distance along the stacking direction of the black matrix layer 3 and the display layer 1 is fixed. Therefore, the angle θ2, that is, the display viewing angle range of the first type of pixel unit 12, is mainly affected by the black matrix-opening distance d1 between the projection of the first end 31a of the frame edge 310 of the black matrix frame 31 on the display layer 1 and the edge of the light outlet K1.

[0122] See also Fig. 9 , is a curve diagram showing the relationship between viewing angle and display brightness at different black matrix-opening distances obtained through simulation tests.

[0123] in, Fig. 9 Schematic diagram of the relationship between viewing angle and display brightness of the simulation test when the black matrix-opening distance d1 is 0.5μm, 1μm, 2μm, 3μm, 4μm and the normal distance L21, L22, L23, L24, L25, L26 are shown respectively.

[0124] in, Fig. 9 The viewing angle in the image may be a viewing angle. As mentioned above, the viewing angle may also be the angle between the line of sight and the normal line L1 of the pixel unit 11, which is also equivalent to the display viewing angle corresponding to when the display panel 100 emits light at a corresponding angle. Fig. 9 It can be seen that the smaller the black matrix-opening distance d1 is, the greater the viewing angle is, the more the brightness attenuates, and when the attenuation reaches a certain level, it is equivalent to being invisible, indicating that the light emitted by the display panel 100 at this viewing angle / display angle is basically invisible, that is, when the black matrix-opening distance d1 is smaller, the display angle range of the pixel unit 11, that is, the visible angle range, is smaller, and the anti-peeping effect is better.

[0125] For example, Fig. 9 The size of the light outlet K1 of the pixel unit 11 may be the size along the row direction, and the display viewing angle may be the angle between the light outlet K1 and the normal line L1 when viewed from the row direction.

[0126] In some embodiments, in the present application, a black matrix-opening distance d1 between a projection of a first end 31a of a frame edge 310 of the black matrix frame 31 on the display layer 1 and an edge of the light outlet K1 is between 0.5 μm and 3 μm.

[0127] Please return to Figure 5, among which, Figure 5 As shown, the display panel 100 further includes a touch layer 2. The touch layer 2 is stacked on the display layer 1 and located between the display layer 1 and the black matrix layer 3, and the black matrix layer 3 is stacked on the touch layer 2. The touch layer 2 includes a plurality of metal traces 21 distributed in a determinant, and the plurality of metal traces 21 distributed in a determinant cross to form a light-transmitting area Q1 for light from the pixel unit 11 to pass through.

[0128] That is, in some embodiments, the display panel 100 also includes a touch layer 2, which includes a plurality of metal traces 21 distributed in a matrix to realize a touch function and can form a light-transmitting area Q1 for light from the pixel unit 11 to pass through without affecting the luminous display of the pixel unit 11.

[0129] In the present application, a plurality of metal traces 21 distributed in a matrix on the touch layer 2 cross to form a light-transmitting area Q1 for light from the pixel unit 11 to pass through, and since the projection of the black matrix frame 31 on the display layer 1 surrounds the corresponding first type pixel unit 12, as shown in FIG. Figure 5 As shown, the black matrix frame 31 actually also surrounds and forms a light-transmitting area Q2 for the light of the first type of pixel unit 12 to further pass through. Therefore, for the first type of pixel unit 12, the outgoing light of the first type of pixel unit 12 with a smaller angle with the normal line L1 can pass through the light-transmitting area Q1 formed by the intersection of the multiple metal traces 21 distributed in a determinant on the touch layer 2 and the light-transmitting area Q2 formed by the black matrix frame 31. Among them, when there are multiple through holes distributed on the black matrix layer 3, and each through hole is set corresponding to each first type of pixel unit 12, the area corresponding to the through hole is also the light-transmitting area Q2.

[0130] See also Fig.10 , is a plan view of the touch layer 2 of the display panel 100 in some embodiments of the present application.

[0131] Among them, in some embodiments, as mentioned above Figure 2 As shown in the figure, each first-type pixel unit 12 includes three first-type sub-pixel units 121, and each second-type pixel unit 13 also includes three second-type sub-pixel units 131, wherein Fig.10 As shown, the plurality of metal wirings 21 distributed in columns include a plurality of first metal wirings 211 extending in the row direction and spaced apart from each other, and a plurality of second metal wirings 212 extending in the column direction and spaced apart from each other. The plurality of first metal wirings 211 and the plurality of second metal wirings 212 cross-enclose and form a plurality of light-transmitting areas Q1, wherein each light-transmitting area Q1 corresponds to a sub-pixel unit to allow the corresponding sub-pixel unit to emit light.

[0132] In some embodiments, the plurality of first metal traces 211 extending in the row direction and spaced apart from each other and the plurality of second metal traces 212 extending in the column direction and spaced apart from each other are located in different layers in the touch layer 2, and the plurality of first metal traces 211 and the plurality of second metal traces 212 cross and enclose to form a plurality of light-transmitting areas Q1, which means that the projection of the plurality of first metal traces 211 on the layer where the plurality of second metal traces 212 are located intersects with the plurality of second metal traces 212. Wherein, the touch layer 2 is a capacitive touch structure. Each intersection of the first metal trace 211 and the second metal trace 212 corresponds to a touch point, wherein, in response to pressing a certain position of the display panel 100, the distance between the first metal trace 211 and the second metal trace 212 at the corresponding position will change, so that a corresponding capacitance change is generated at the position, which can reflect that a touch has occurred at the current position, thereby realizing a touch function.

[0133] In some embodiments, since the size of the light exit port K1 of the first type of sub-pixel unit 121 is smaller than the size of the light exit port K1 of the second type of sub-pixel unit 131, the area of ​​the light-transmitting region Q1 corresponding to the first type of sub-pixel unit 121 is smaller than the area of ​​the light-transmitting region Q1 corresponding to the second type of sub-pixel unit 131.

[0134] Thus, in some embodiments, the area of ​​the light-transmitting region Q1 corresponding to the first-type sub-pixel unit 121 is smaller than the area of ​​the light-transmitting region Q1 corresponding to the second-type sub-pixel unit 131, so that the first-type sub-pixel unit 121 can be shielded from more light by the matrix-distributed metal wiring 21, thereby making the display viewing angle range of each first-type sub-pixel unit 121 in the first-type pixel unit 12 smaller than the display viewing angle range of each corresponding second-type sub-pixel unit 131 in the second-type pixel unit 13, thereby further ensuring that the display viewing angle range of the first-type pixel unit 12 is smaller than the display viewing angle range of the second-type pixel unit 13.

[0135] Among them, in the present application, the size of the light exit K1 of the first type of sub-pixel unit 121 / first pixel unit 12 is smaller than the size of the light exit K1 of the second type of sub-pixel unit 131 / second type of pixel unit 13, and is illustrated by taking the example that the size of the light exit K1 of the first type of sub-pixel unit 121 / first pixel unit 12 in the row direction is smaller than the size of the light exit K1 of the second type of sub-pixel unit 131 / second type of pixel unit 13 in the row direction, while the sizes of the two in the column direction are equal.

[0136] See also Fig.11 , is a schematic diagram of a stacking structure of more layers of the display panel 100 in some embodiments of the present application.

[0137] like Fig.11 As shown, the area outside the black matrix frame 31 in the black matrix layer 3 is provided with optical glue 32, and the black matrix layer 3 is fixedly connected to the touch layer 2 by bonding and fixing the optical glue 32. The optical glue 32 is a light-transmitting glue that allows light to pass through.

[0138] That is, in some embodiments, the black matrix layer 3 and the optical adhesive layer formed by the optical adhesive 32 are co-layered, so that the light shielding function of the black matrix and the bonding and fixing function of the optical adhesive can be realized at the same time.

[0139] The thickness of the black matrix frame 31 may be the same as the thickness of the black matrix layer 3, or may be less than the thickness of the black matrix layer 3. For example, the thickness of the black matrix frame 31 may be the same as the thickness of the black matrix layer 3, and an optical glue 32 of the same thickness is arranged in the area outside the black matrix frame 31 in the black matrix layer 3 to form a complete black matrix layer 3. For another example, the thickness of the black matrix frame 31 may be less than the thickness of the black matrix layer 3, and the optical glue 32 may be stacked with the black matrix frame 31 so that the thickness of the area where the black matrix frame 31 is located is the same as the thickness of the black matrix layer 3, and in addition, the optical glue 32 of the same thickness as the thickness of the black matrix layer 3 is filled in other areas to form a complete black matrix layer 3.

[0140] In some embodiments, Fig.11 As shown, the display panel 100 further includes an encapsulation layer 4, which is disposed between the display layer 1 and the touch layer 2. The encapsulation layer 4 is used to encapsulate the display layer 1 and to bond and fix the display layer 1 and the touch layer 2 together.

[0141] In some embodiments, Fig.11 As shown, the display panel 100 further includes a driving layer 5 , which is disposed on a side of the display layer 1 away from the touch layer 2 and is used to drive the pixel units 11 of the display layer 1 to emit light.

[0142] That is, in some embodiments, the display panel 100 may further include a driving layer 5 to drive the pixel units 11 of the display layer 1 to emit light.

[0143] In some embodiments, the driving layer 5 may include a TFT thin film transistor array, and the driving layer 5 is connected between the driving circuit and the pixel units 11 distributed in rows and columns, and is used to apply the driving voltage provided by the driving circuit to the corresponding pixel units 11 to drive the pixel units 11 to emit light and display.

[0144] Among them, as mentioned above, the sub-pixel unit included in the pixel unit 11 can be an OLED, the cathode of the OLED is grounded, and the anode is connected to the driving layer 5, and the driving layer 5 is used to control the driving voltage provided by the driving circuit to be applied to the anode of at least part of the sub-pixel units in the corresponding pixel unit 11, so that at least part of the sub-pixel units in the corresponding pixel unit 11 are powered on and emit light, so that the at least part of the sub-pixel units that emit light generate light of corresponding colors and are mixed into the color finally presented by the corresponding pixel unit 11, so that the pixel unit 11 displays the corresponding color.

[0145] In some embodiments, the driving layer 5 includes structural layers such as a planar layer and a buffer layer in terms of a stacking structure, which will not be described in detail here.

[0146] In some embodiments, the driving layer 5 is used to drive at least the second-type pixel unit 13 of the display layer 1 to emit light, or only drive the first-type pixel unit 12 to emit light.

[0147] That is, in some embodiments, the driving layer 5 can drive the second type of pixel unit 13 of the display layer 1 to emit light, or the second type of pixel unit 13 and the first type of pixel unit 12 of the display layer 1 can both emit light, so that, since the display viewing angle range of the second type of pixel unit 13 is large, it can be applied to scenes where anti-peeping is not required, and the display effect can be improved. Alternatively, the driving layer 5 can only drive the first type of pixel unit 12 of the display layer 1 to emit light, and since the display viewing angle range of the first type of pixel unit 12 is small, in scenes where anti-peeping is required, only the first type of pixel unit 12 of the display layer 1 can be driven to emit light, which can effectively achieve anti-peeping.

[0148] Among them, Fig.11 As shown, the display panel 100 further includes a polarizer layer 6 , and the polarizer layer 6 is stacked on a side of the black matrix layer 3 away from the touch layer 2 .

[0149] like Fig.11 As shown, the display panel 100 further includes a first optical adhesive layer 7 , which is disposed between the polarizer layer 6 and the black matrix layer 3 , and is used to bond and fix the polarizer layer 6 and the black matrix layer 3 .

[0150] Among them, Fig.11 As shown, the display panel 100 further includes a protective layer 8 , which is stacked on a side of the polarizer layer 6 away from the black matrix layer 3 and can serve as the outermost layer of the display panel 100 .

[0151] The side of the protective layer 8 facing away from the polarizer layer 6 is the light emitting side of the display panel 100 , that is, the display side.

[0152] In some embodiments, Figure 8 As shown, the display panel 100 further includes a second optical adhesive layer 23 , which is disposed between the touch layer 2 and the black matrix layer 3 , and is used to bond and fix the touch layer 2 and the black matrix layer 3 .

[0153] like Fig.11 As shown, the display panel 100 further includes a base layer 9 , which is disposed on a side of the driving layer 5 away from the display layer 1 , and is used as a base of the display panel 100 and supports other layers of the display panel 100 .

[0154] In some embodiments, Figure 2 The shapes of the sub-pixel units included in the pixel unit 11 in the figure, that is, the first type of sub-pixel unit 121 and the second type of sub-pixel unit 131, are the shapes of the light outlets K1 of the sub-pixel units included in the pixel unit 11.

[0155] The light outlet K1 of the sub-pixel unit included in the pixel unit 11 in the present application is an opening formed on the (Pixel Definition Layer, PDL pixel definition layer), that is, it can also be called the opening of the sub-pixel unit.

[0156] Among them, Figure 2 As shown in the figures, the openings of the first sub-pixel units 121 and the second sub-pixel units 131 are square. Obviously, the openings of the first sub-pixel units 121 and the second sub-pixel units 131 can also be other shapes such as circular, elliptical, polygonal or diamond.

[0157] Among them, the shape of the black matrix sub-frame 311 corresponding to the first-type sub-pixel unit 121 can be the same as the shape of the first-type sub-pixel unit 121, that is, when the openings of those first-type sub-pixel units 121 are square, the shape of the black matrix sub-frame 311 corresponding to the first-type sub-pixel unit 121 is also square, and when the openings of those first-type sub-pixel units 121 are circular, elliptical, polygonal or diamond-shaped, the shape of the black matrix sub-frame 311 corresponding to the first-type sub-pixel unit 121 is also circular, elliptical, polygonal or diamond-shaped.

[0158] The shape of the black matrix sub-frame 311 corresponding to the first-type sub-pixel unit 121 is the shape of the projection of the black matrix sub-frame 311 of the first-type sub-pixel unit 121 on the display layer 1 .

[0159] In some embodiments, when the opening of the first type of sub-pixel unit 121 and the shape of the black matrix sub-frame 311 corresponding to the first type of sub-pixel unit 121 are circular or the like, the aforementioned Figure 1-Figure 2 The screenshots in the figure may be screenshots in any direction, and the size of the light-transmitting area Q1 corresponding to the first type of sub-pixel unit 121 along any direction is smaller than the size of the light-transmitting area Q1 corresponding to the second type of sub-pixel unit 131 along the corresponding direction.

[0160] In some embodiments, an encapsulation layer formed by COE (color filter onencapsulation) technology may also be provided above the black matrix layer 3. Since the encapsulation layer formed by COE technology can achieve the effect of the polarizer layer 6, the polarizer layer 6 can be omitted at this time. In addition, since the COE encapsulation layer itself has a black matrix structure, it can accelerate the attenuation of a large viewing angle, which is beneficial to improving the anti-peeping effect. Among them, the black matrix structure in the COE encapsulation layer is located at a position corresponding to the first type of pixel unit 12, that is, the projection of the black matrix structure in the COE encapsulation layer on the display layer 1 can also surround the corresponding first type of pixel unit 12, and specifically can surround the first type of sub-pixel unit 121 in the corresponding first type of pixel unit 12.

[0161] In some embodiments, an MLA (microlens array) structure layer having material properties with different high and low refractive indices may also be provided above the black matrix layer 3, and the MLA structure layer may include multiple MLA structures, which can further enhance the anti-peeping effect and reduce power consumption by 12%. The multiple MLA structures included in the MLA structure layer are located at positions corresponding to the first type of pixel unit 12, that is, the projections of the multiple MLA structures included in the MLA structure layer on the display layer 1 may also surround the corresponding first type of pixel unit 12, and specifically surround the first type of sub-pixel unit 121 in the corresponding first type of pixel unit 12.

[0162] In some embodiments, an MLA (microlens array) structure and an encapsulation layer formed by COE technology may be stacked on top of the black matrix layer 3 at the same time. For example, the encapsulation layer formed by the COE technology and the MLA (microlens array) structure may be stacked in sequence on top of the black matrix layer 3, thereby better improving the anti-peeping effect.

[0163] See also Fig.12 , which is a partial top view illustrating a partial structure of the display panel 100 in some embodiments of the present application.

[0164] in, Fig.12The schematic diagram shows that the projections of a plurality of MLA structures S1 on the display layer 1 surround the first-type sub-pixel units 121 in the corresponding first-type pixel units 12 .

[0165] Among them, Fig.12 As shown, the shape of the first type of sub-pixel unit 121 is illustrated as a circle, the shape of the MLA structure S1 is illustrated as a square, and the hollow area formed by the MLA structure S1 is also a circle, which is consistent with the shape of the first type of sub-pixel unit 121 and surrounds the first type of sub-pixel unit 121.

[0166] As mentioned above, the MLA structure layer may include a plurality of MLA structures S1, which can further enhance the anti-peeping effect and reduce power consumption by 12%.

[0167] Therefore, the display panel 100 of the present application includes a plurality of first-type pixel units 12 and a plurality of second-type pixel units 13, and the light outlet K1 of the first-type pixel unit 12 is smaller than the light outlet K1 of the second-type pixel unit 13. Therefore, since the light outlet K1 of the first-type pixel unit 12 is smaller, the angle of light path divergence will be smaller, so that the display viewing angle range of the first-type pixel unit 12 can be smaller than the display viewing angle range of the second-type pixel unit 13. Therefore, the display panel 100 can emit light only through the first-type pixel unit 12 with a smaller display viewing angle range when necessary, and since the display viewing angle range of the first-type pixel unit 12 is smaller, a better anti-peeping effect can be achieved. In some embodiments, the display panel 100 also includes a black matrix layer 3, wherein the black matrix layer 3 is stacked on the light emitting surface of the display layer 1, wherein the light emitting surface is the surface on which the light outlet K1 is provided, wherein the black matrix layer 3 includes a plurality of black matrix frames 31, each black matrix frame 31 corresponds to a first type of pixel unit 12, and the projection on the display layer 1 at least partially surrounds the corresponding first type of pixel unit 12, and the black matrix frame 31 is used to block part of the light emitting path of the first type of pixel unit 12, thereby further limiting the display viewing angle range of the first type of pixel unit 12.

[0168] See also Fig.13 , is a schematic diagram of the stacking of the display screen 110 in some embodiments of the present application.

[0169] The display screen 110 includes the display panel 100 in any of the aforementioned embodiments, and further includes a glass cover plate 111 .

[0170] The glass cover plate 111 is stacked on the light emitting surface of the display panel 100 , that is, one side of the display surface, and serves as a protection plate for the display screen 110 .

[0171] See also Fig.14 , which is a plan view of an electronic device 200 in some embodiments of the present application.

[0172] The electronic device 200 includes the aforementioned display screen 110 , that is, also includes the display panel 100 in any of the aforementioned embodiments.

[0173] In some embodiments, the display screen 110 is a touch display screen, thereby realizing the functions of touch input and display output.

[0174] Among them, Fig.14 As shown, the electronic device 200 includes a top end D1, a bottom end D2 and two side ends D3.

[0175] In some embodiments, when the electronic device 200 is in normal use, the top D1 is generally located at the top, or at the end away from the user.

[0176] In some embodiments, the aforementioned row direction may refer to the direction from one side end D3 of the electronic device 200 to the other side end D3 when the display panel 100 is installed in the electronic device 200, and the aforementioned column direction may refer to the direction from the top end D1 to the bottom end D2 or the bottom end D2 to the top end D1 of the electronic device 200 when the display panel 100 is installed in the electronic device 200.

[0177] Among them, the directional terms such as "top" and "bottom" used in the embodiments of the present application to describe the electronic device 200 are mainly explained based on the orientation when the user holds the electronic device 200 and uses it. The position toward the top side of the electronic device 200 is the "top", and the position toward the bottom side of the electronic device 200 is the "bottom". It does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the orientation of the electronic device 200 in actual application scenarios. In some embodiments, the bottom end D2 of the electronic device 200 is the end where the headphone jack and the USB port are provided, and the top end D1 of the electronic device 200 is the other end opposite to the end where the headphone jack and the USB port are provided, and may also refer to the end where a camera, a receiver, etc. are provided.

[0178] In some embodiments, the display mode of the electronic device 200 includes a normal display mode and an anti-peeping display mode. In the normal display mode, at least the second-type pixel unit 13 of the display panel 100 emits light. In the anti-peeping display mode, only the first-type pixel unit 12 in the display panel 100 emits light.

[0179] As mentioned above, when only the first type of pixel unit 12 is used for light display, a better anti-peeping effect can be achieved due to the small display viewing angle range of the first type of pixel unit 12. In addition, in the present application, the black matrix frame 31 cooperates with the metal wiring 21 of the touch layer 2 to block part of the light output path of the first type of pixel unit 12, which can achieve a larger range of blocking and effectively improve the anti-peeping effect. In addition, in the present application, there is no need to add a new process. Only by adjusting the width of the metal wiring 21 of the touch layer 2 and the width of the frame edge 310 of the black matrix frame 31 of the black matrix layer 3, a better anti-peeping effect can be achieved, and the process is simple.

[0180] When at least the second-type pixel unit 13 of the display panel 100 emits light for display, that is, only the second-type pixel unit 13 emits light for display, or both the second-type pixel unit 13 and the first-type pixel unit 12 emit light for display, since the second-type pixel unit 13 has less viewing angle occlusion, normal display can be performed in a larger display viewing angle range.

[0181] The structure of the display panel 100 included in the electronic device 200 can be found in the above-mentioned introduction of the display panel 100 for more details, which will not be described again here.

[0182] See also Fig.15 , which is a structural block diagram of an electronic device 200 in some embodiments of the present application.

[0183] like Fig.15 As shown, the electronic device 200 includes the display panel 100 and a processor 101 .

[0184] The processor 101 may be used to control the display mode of the electronic device 200 to switch to the normal display mode or the anti-peeping display mode.

[0185] For example, the processor 101 may control the electronic device 200 to enter the anti-peeping display mode in response to the anti-peeping on operation, for example, the processor 101 may control the driving layer 5 of the display panel 100 to only conduct the electrical connection between the driving circuit and the first type of pixel unit 12, and only drive the first type of pixel unit 12 to emit light and display. The processor 101 may also control the electronic device 200 to enter the normal display mode in response to the anti-peeping off operation, for example, the processor 101 may control the driving layer 5 of the display panel 100 to conduct the electrical connection between the driving circuit and the second type of pixel unit 13, or conduct the connection between the driving circuit and all the pixel units 11, and drive the second type of pixel unit 13 to emit light and display, or drive all the pixel units 11, that is, all the first type of pixel units 12 and the second type of pixel units 13 to emit light and display.

[0186] In some embodiments, Fig.15 As shown, the electronic device 200 further includes an input unit 102 . The anti-peeping on operation and the anti-peeping off operation may be operations inputted through the input unit 102 .

[0187] In some embodiments, the anti-peeping on operation or the anti-peeping off operation may be an operation of entering a function menu option through the input unit 102 and selecting a “turn on detection” or “turn off detection” function option.

[0188] In some embodiments, the input unit 102 is the display panel 100, and the detection-on operation and the detection-off operation may be touch gesture operations with specific touch tracks input on the display panel 100. For example, the detection-on operation may be a touch gesture operation with a “√”-shaped track input on the touch screen, and the detection-off operation may be a touch gesture operation with a “×”-shaped track input on the touch screen, and so on.

[0189] In some embodiments, the input unit 102 may also include physical buttons, such as a power button and / or a volume button located on the side frame of the electronic device 200. The detection-on operation and the detection-off operation may be specific pressing operations performed on the physical buttons. For example, the detection-on operation and the detection-off operation may both be operations of pressing the volume button and the power button at the same time. When the detection function is currently in the on state, the operation of pressing the volume button and the power button at the same time is the detection-off operation, and when the detection function is currently in the off state, the operation of pressing the volume button and the power button at the same time is the detection-on operation, and when the detection function is currently in the off state, the operation of pressing the volume button and the power button at the same time is the detection-on operation, and so on.

[0190] The electronic device 200 also includes a memory, a battery, etc., which are irrelevant to the improvement of the present application and will not be described in detail.

[0191] The electronic device 200 of the present application may be a mobile phone, a tablet computer, a laptop computer or other electronic device.

[0192] The display panel 100, the display screen 110 and the electronic device 200 in the present application include a plurality of first-type pixel units 12 and a plurality of second-type pixel units 13, and the light outlet K1 of the first-type pixel unit 12 is smaller than the light outlet K1 of the second-type pixel unit 13. Therefore, since the light outlet K1 of the first-type pixel unit 12 is smaller, the angle of light path divergence will be smaller, so that the display viewing angle range of the first-type pixel unit 12 can be smaller than the display viewing angle range of the second-type pixel unit 13. Therefore, the display panel 100 can emit light and display only through the first-type pixel unit 12 with a smaller display viewing angle range when necessary, and since the display viewing angle range of the first-type pixel unit 12 is smaller, a better anti-peeping effect can be achieved. In some embodiments, the display panel 100 also includes a black matrix layer 3, wherein the black matrix layer 3 is stacked on the light emitting surface of the display layer 1, wherein the light emitting surface is a surface on which the light outlet K1 is provided, and wherein the black matrix layer 3 is used to block part of the light emitting path of the first type of pixel unit 12, thereby further limiting the display viewing angle range of the first type of pixel unit 12.

[0193] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0194] The above description is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application; in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
