[0034] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0035] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0036] Figure 1 This is a schematic diagram of the structure of a display panel provided in an embodiment of the present invention, such as... Figure 1 As shown, the display panel includes multiple pixel units 10, each pixel unit 10 including a shared pixel 11 and a privacy pixel 12; the shared pixel 11 includes at least a first color shared pixel 111 and at least one second color shared pixel 112; the privacy pixel 12 includes at least one second color privacy pixel 122; the first color shared pixel 111 is located in the central region of the pixel unit 10, and the second color shared pixel 112 and the second color privacy pixel 122 are symmetrical about the first color shared pixel 111; in the sharing mode, the first color shared pixel 111 and the second color shared pixel 112 emit light, while the second color privacy pixel 122 does not emit light; in the privacy mode, the first color shared pixel 111 and the second color privacy pixel 122 emit light, while the second color shared pixel 112 does not emit light.

[0037] The display panel includes multiple pixel units 10, which are used to achieve the display effect of the display panel. The multiple pixel units 10 can be arranged in an array or in a virtual quadrilateral arrangement, etc. The specific arrangement method can be selected according to the actual design requirements, and the embodiments of the present invention do not impose specific limitations. Figure 1The image shows pixel units 10 arranged in an array. Pixel units 10 share a pixel 11 and a privacy pixel 12. The shared pixel 11 is a pixel with a normal display viewing angle. The privacy pixel 12 can be a pixel with a specific display viewing angle, or it can be a pixel with a normal display viewing angle but surrounded by an optical layer to suppress its emitted light in a specific direction, so that the emitted light of the privacy pixel 12 has a specific display viewing angle. The shared pixel 11 includes at least a first color shared pixel 111 and at least one second color shared pixel 112. The first color shared pixel 111 and the second color shared pixel 112 are different colors. For example, the first color shared pixel 111 can be a blue shared pixel, and the second color shared pixel 112 can be a red shared pixel or a green shared pixel. The privacy pixel 12 includes at least one second-color privacy pixel 122. The number of second-color shared pixels 112 and the number of second-color privacy pixels 122 in the same pixel unit 10 can be selected according to actual design requirements. To ensure the display effect in both sharing mode and privacy mode, the number of second-color shared pixels 112 and the number of second-color privacy pixels 122 in the same pixel unit 10 can be the same, ensuring that the PPI does not decrease when the display panel switches display modes. In this application, we take a pixel unit 10 including two second-color shared pixels 112 and two second-color privacy pixels 122 as an example. The first-color shared pixel 111 is located in the central area of ​​the pixel unit 10, which can ensure stable light output of the first-color shared pixel 111 in both sharing mode and privacy mode. The second-color shared pixel 112 and the second-color privacy pixel 122 are symmetrical about the first-color shared pixel 111. The symmetrical arrangement of the shared pixels 11 and privacy pixels 12 of the same color ensures the display uniformity of the display panel in different display modes, ensures the display effect, and also reduces the manufacturing difficulty and complexity. In shared mode, the first color-sharing pixel 111 in the central area and the second color-sharing pixels 112 surrounding it emit light, while the second color privacy pixel 122 does not emit light. This allows for the emission of light from both the front and wide viewing angles, ensuring normal display performance. In privacy mode, the first color-sharing pixel 111 in the central area and the second color privacy pixel 122 surrounding it emit light, while the second color-sharing pixel 112 does not emit light. This allows for the emission of light from the front viewing angle, while blocking light from wide viewing angles. This makes it difficult to see the displayed content when observing the display panel from the side at wide viewing angles, thus achieving privacy protection and preventing information leakage.

[0038] This invention provides an embodiment of the invention that sets a first color-sharing pixel, at least one second color-sharing pixel, and at least one second color privacy pixel in the same pixel unit. The first color-sharing pixel is set to be in an luminous state in both sharing mode and privacy mode. By adjusting the second color-sharing pixel and the second color privacy pixel to be turned on at different times, the display panel can freely switch between sharing mode and privacy mode to meet the display needs in different scenarios and ensure the display effect without changing the PPI of the display panel.

[0039] Based on the above embodiments, the second color sharing pixel 112 and the second color privacy pixel 122 can have different settings. The following describes two feasible settings in detail.

[0040] As one possible implementation method, please refer to [reference]. Figure 1 At least one of the second color sharing pixel 112 and the second color privacy pixel 122 is located at the top corner of the pixel unit 10. For example, by setting the second color sharing pixel 112 and the second color privacy pixel 122 at the top corner of the pixel unit 10, the second color sharing pixel 112, the second color privacy pixel 122, and the first color sharing pixel 111 are located on the same straight line, which can effectively reduce light crosstalk in sharing mode and privacy mode, and ensure the sharing effect and privacy effect.

[0041] As another possible implementation method Figure 2 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figure 2 As shown, at least one of the second color-sharing pixel 112 and the second color privacy pixel 122 has a first spacing 'a' with any edge of pixel unit 10. Figure 2 As shown, a first spacing a exists between the second color sharing pixel 112 and any edge of the pixel unit 10; and a first spacing a exists between the second color privacy pixel 122 and any edge of the pixel unit 10. This can prevent the second color sharing pixel 112 from causing optical crosstalk to the adjacent pixel unit 10 when it emits light, and prevent the second color privacy pixel 122 from causing optical crosstalk to the adjacent pixel unit 10 when it emits light, thus ensuring the display effect.

[0042] Optional, continue to refer to Figure 1 and Figure 2 The shared pixel 11 also includes at least one third color shared pixel 113; the privacy pixel 12 includes at least one third color privacy pixel 123; the third color shared pixel 113 and the third color privacy pixel 123 are centrally symmetrical about the first color shared pixel 111.

[0043] The shared pixel 11 may also include at least one third-color shared pixel 113, and the privacy pixel 12 includes at least one third-color privacy pixel 123. The shared pixel 11 and privacy pixel 12 of the same color are symmetrically arranged to ensure the uniformity of the display panel in different display modes, ensure the display effect, and reduce the manufacturing difficulty and complexity.

[0044] Furthermore, the third color-shared pixel 113 has a different color from the second color-shared pixel 112. When the second color-shared pixel 112 is a green shared pixel, the third color-shared pixel 113 is a red shared pixel; when the second color-shared pixel 112 is a red shared pixel, the third color-shared pixel 113 is a green shared pixel. In this application, an example is given where the second color-shared pixel 112 is a green shared pixel and the third color-shared pixel 113 is a red shared pixel.

[0045] Figure 3 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figure 3 As shown, a second spacing b exists between the third color sharing pixel 113 and any edge of the pixel unit 10; and a second spacing b exists between the third color privacy pixel 123 and any edge of the pixel unit 10. This can prevent the third color sharing pixel 113 from causing optical crosstalk to the adjacent pixel unit 10 when it emits light, and prevent the third color privacy pixel 123 from causing optical crosstalk to the adjacent pixel unit 10 when it emits light, thus ensuring the display effect.

[0046] Figure 4 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figure 4 As shown, a first spacing 'a' exists between the second color-sharing pixel 112 and any edge of the pixel unit 10; and a first spacing 'a' exists between the second color privacy pixel 122 and any edge of the pixel unit 10. A second spacing 'b' exists between the third color-sharing pixel 113 and any edge of the pixel unit 10; and a second spacing 'b' exists between the third color privacy pixel 123 and any edge of the pixel unit 10. In the sharing mode, the second color-sharing pixel 112 and the third color-sharing pixel 113 can avoid optical crosstalk to adjacent pixel units 10 when they emit light; in the privacy mode, the second color privacy pixel 122 and the third color privacy pixel 123 can avoid optical crosstalk to adjacent pixel units 10 when they emit light, thus ensuring the display effect.

[0047] Optional, continue to refer to Figure 2The first spacing is 'a', where 0μm < a < 15μm. By appropriately setting the value of the first spacing 'a' between the first color-sharing pixel 111 and any edge of the pixel unit 10, and the value of the first spacing 'a' between the first color privacy pixel 12 and any edge of the pixel unit 10, the risk of optical crosstalk can be effectively reduced, ensuring the display effect of the display panel in different display modes.

[0048] Similarly, continue to refer to Figure 3 The second pitch is b, where 0μm < b < 15μm. Appropriately setting the value of the second pitch b effectively reduces the risk of optical crosstalk and ensures the display effect of the display panel in different display modes. Furthermore, the values ​​of the first pitch a and the second pitch b can be the same or different, depending on the actual design requirements to guarantee the display panel's display effect.

[0049] Optional, Figure 5 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 6 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 7 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 8 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 9 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 10 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, there are at least some adjacent pixel units 10 where second color shared pixels 112 are adjacent and there are at least some adjacent pixel units 10 where second color privacy pixels 122 are adjacent; and / or, there are at least some adjacent pixel units 10 where the second color shared pixels 112 in one pixel unit 10 are adjacent to the second color privacy pixels 122 in another adjacent pixel unit 10.

[0050] Among them, such as Figure 5 As shown, along the row direction, some adjacent pixel units 10 have second color-sharing pixels 112 arranged adjacently, and some adjacent pixel units 10 also have second color privacy pixels 122 arranged adjacently. Or as... Figure 6As shown, along the column direction, some adjacent pixel units 10 have second color-sharing pixels 112 arranged adjacently, and some adjacent pixel units 10 also have second color privacy pixels 122 arranged adjacently. Both of these methods can avoid the risk of light crosstalk between adjacent pixel units 10 when the second color-sharing pixels 112 or the second color privacy pixels 122 are lit simultaneously, thus ensuring the display effect of the display panel in different display modes.

[0051] like Figure 7 As shown, along the row direction, the second color-sharing pixel 112 in one pixel unit 10 is arranged adjacent to the second color privacy pixel 122 in another adjacent pixel unit 10, or, as... Figure 8 As shown, along the column direction, in adjacent pixel units 10, the second color-sharing pixel 112 in one pixel unit 10 is arranged adjacent to the second color privacy pixel 122 in another adjacent pixel unit 10. This ensures the display uniformity of pixel units 10 in both sharing mode and privacy mode. Furthermore, as... Figure 9 As shown, a first distance 'a' can be set between the second color-sharing pixel 112 in a pixel unit 10 and any edge of the pixel unit 10, and between the second color-sharing pixel 112 in an adjacent pixel unit 10 and any edge of the pixel unit 10. This can prevent optical crosstalk between the second color-sharing pixel 112 and the second color privacy pixel 122 when the second color-sharing pixel 112 is emitting light, and also prevent optical crosstalk between the second color privacy pixel 122 and the second color-sharing pixel 112 when the second color privacy pixel 122 is emitting light. Similarly, a second distance 'b' can be set between the third color-sharing pixel 113 in a pixel unit 10 and any edge of the pixel unit 10, and between the third color-sharing pixel 113 in an adjacent pixel unit 10. This can prevent optical crosstalk between the third color-sharing pixel 113 and the third color privacy pixel 123 when the third color privacy pixel 123 is emitting light, and also prevent optical crosstalk between the third color-sharing pixel 113 and the third color privacy pixel 123 when the third color privacy pixel 123 is emitting light.

[0052] like Figure 10 As shown, along the row direction, some adjacent pixel units 10 have second color shared pixels 112 arranged adjacently, and some adjacent pixel units 10 have second color privacy pixels 122 arranged adjacently; and along the row direction, some adjacent pixel units 10 have second color shared pixels 112 arranged adjacently with the second color privacy pixels 122 of another adjacent pixel unit 10, so as to ensure the display effect of the display panel in different display modes.

[0053] Optional, Figure 11 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 12This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figure 11 and Figure 12 As shown, the centers of adjacent second color-sharing pixels 112 are located on the circumference of the same virtual circle, and the centers of adjacent second color privacy pixels 122 are located on the circumference of the same virtual circle; or, the centers of adjacent second color-sharing pixels 112 and the centers of adjacent second color privacy pixels 122 are located on the circumference of the same virtual circle.

[0054] Among them, such as Figure 11 As shown, a repeating unit consisting of four pixel units 10 has four adjacent second-color shared pixels 112 whose centers are located on the circumference of the same virtual circle, and adjacent second-color privacy pixels 122 whose centers are located on the circumference of the same virtual circle. Figure 12 As shown, a repeating unit consisting of four pixel units 10 has its center of the adjacent second color shared pixel 112 and the center of the second color privacy pixel 122 located on the circumference of the same virtual circle. During the fabrication of the second color shared pixels 112 and / or the second color privacy pixels 122 located on the circumference of the same virtual circle, the same mask can be used for vapor deposition, effectively reducing the number of masks and lowering the fabrication cost.

[0055] Optional, Figure 13 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figure 13 As shown, the display panel also includes a light-shielding layer 13, which includes at least a first opening 131 and a second opening 132; a pixel definition layer 14, which includes a first pixel opening 141 and a second pixel opening 142, a shared pixel 11 located within the first pixel opening 141, and a privacy pixel 12 located within the second pixel opening 142; along the thickness direction Z of the display panel, the first opening 131 overlaps with the first pixel opening 141, and the second opening 132 overlaps with the second pixel opening 142; along a plane parallel to the display panel, the width W1 of the first opening 131 is greater than the width W2 of the second opening 132.

[0056] The display panel also includes a light-shielding layer 13 and a pixel definition layer 14. The light-shielding layer 13 effectively isolates light emitted from adjacent pixel units 10, avoiding optical crosstalk. The pixel definition layer 14 has pixel openings, the shape and size of which determine the light-emitting area and shape of the sub-pixels, thereby controlling the aperture ratio. The pixel definition layer 14 has a first pixel opening 141 and a second pixel opening 142. A shared pixel 11 is formed in the first pixel opening 141, and a privacy pixel 12 is formed in the second pixel opening 142. The light-shielding layer 13 also has a first opening 131 that overlaps with the orthographic projection of the first pixel opening 141 and a second opening 132 that overlaps with the orthographic projection of the second pixel opening 142. These openings are parallel to the plane of the display panel. The width W1 of the first opening 131 is greater than the width W2 of the second opening 132. When the first opening 131 is larger, the frontal and wide-angle light emitted from the shared pixel 11 can exit through the first opening 131, reducing the obstruction of the light-shielding layer 13 and ensuring the display effect in the shared mode. When the second opening 132 is smaller, the wide-angle light emitted from the privacy pixel 12 will be blocked by the shielding layer and will not be emitted, thus ensuring the privacy effect and preventing information leakage.

[0057] Optional, continue to refer to Figure 13 Along the thickness direction Z of the display panel, the projection of the second pixel opening 142 is located within the projection range of the second opening 132, and the minimum distance between the edge of the second opening 132 and the edge of the second pixel opening 142 on the same side is D, where 0μm≤D≤2μm.

[0058] Wherein, along the plane parallel to the display panel, the width W2 of the second opening 132 is greater than the width of the second pixel opening 142, so that along the thickness direction Z of the display panel, the projection of the second pixel opening 142 is located within the projection range of the second opening 132. By reasonably controlling the minimum distance D between the edge of the second opening 132 and the edge of the second pixel opening 142 on the same side, it is ensured that the normal emission of the frontal angle light emitted from the second pixel opening 142 in the privacy mode and the large angle light emitted from the second pixel opening 142 are blocked by the light-shielding layer 13, thereby improving the privacy reliability of the display panel.

[0059] Optional, Figure 14 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figure 1 , Figure 2 and Figure 14 As shown, the line connecting the second color shared pixel 112 and the second color privacy pixel 122 intersects the line connecting the third color shared pixel 113 and the third color privacy pixel 123.

[0060] Among them, the second color-shared pixel 112 and the second color privacy pixel 122 are centrally symmetrical about the first color-shared pixel 111, and the third color-shared pixel 113 and the third color privacy pixel 123 are centrally symmetrical about the first color-shared pixel 111. For example... Figure 2 As shown, the line connecting the second color-shared pixel 112 and the second color privacy pixel 122 intersects the line connecting the third color-shared pixel 113 and the third color privacy pixel 123, with the included angle being either obtuse or acute. Figure 1 and Figure 14 As shown, the line connecting the second color-shared pixel 112 and the second color privacy pixel 122 is perpendicular to the line connecting the third color-shared pixel 113 and the third color privacy pixel 123. The above methods can all ensure that there is a certain spacing between adjacent pixels in adjacent pixel units 10, avoiding optical crosstalk and guaranteeing the display effect of the display panel in different display modes.

[0061] Optional, such as Figure 1 As shown, the light-emitting area of ​​the second color-shared pixel 112 is S21, the light-emitting area of ​​the second color privacy pixel 122 is S22, the light-emitting area of ​​the third color-shared pixel 113 is S31, and the light-emitting area of ​​the third color privacy pixel 123 is S32, where S21=S22 and S31=S32.

[0062] Among them, the light-emitting area S21 of the second color shared pixel 112 and the light-emitting area S22 of the second color privacy pixel 122 can be the same, and the light-emitting area S31 of the third color shared pixel 113 and the light-emitting area S32 of the third color privacy pixel 123 can be the same. When switching between the sharing mode and the privacy mode, the display effect of the display panel is guaranteed and obvious brightness flicker is avoided.

[0063] Optional, Figure 15 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figure 15 As shown, the light-emitting area of ​​the first color-shared pixel 111 is S11, the light-emitting area of ​​the second color-shared pixel 112 is S21, and the light-emitting area of ​​the third color-shared pixel 113 is S31, where S11 > S21, S11 > S31, and S21 ≥ S31.

[0064] Specifically, when the first color-sharing pixel 111 is a blue-sharing pixel, the second color-sharing pixel 112 is a green-sharing pixel, and the third color-sharing pixel 113 is a red-emitting pixel, the emitting area S11 of the first color-sharing pixel 111 can be set to be greater than the emitting area S21 of the second color-sharing pixel 112, and the emitting area S21 of the second color-sharing pixel 112 can be set to be greater than the emitting area S31 of the third color-sharing pixel 113, thereby ensuring the color display effect of the display panel and improving the overall lifespan of the display panel.

[0065] Optional, Figure 16 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. Figure 17 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figure 16 and Figure 17 As shown, the display panel also includes multiple driving circuits 15; adjacent second color shared pixels 112 share the same driving circuit 15; or, adjacent second color privacy pixels 122 share the same driving circuit 15.

[0066] Among them, such as Figure 16 As shown, when the second color-sharing pixels 112 in adjacent pixel units 10 are arranged adjacently, the adjacent second color-sharing pixels 112 share the same driving circuit 15. Figure 17 As shown, when the second-color privacy pixels 122 in adjacent pixel units 10 are arranged adjacently, the adjacent second-color privacy pixels 122 share the same driving circuit 15. Similarly, adjacent third-color privacy pixels 113 can also share the same driving circuit 15; or, adjacent third-color privacy pixels 123 can share the same driving circuit 15. The above methods can effectively reduce the number of driving circuits 15, improve the layout space of driving circuits 15, thereby reducing the electrical risks such as capacitance, image retention, and crosstalk between adjacent driving circuits 15.

[0067] Optional, Figure 18 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figure 18 As shown, the display panel also includes multiple driving circuits 15, including a first driving circuit 151, a second driving circuit 152, and a third driving circuit 153; the first driving circuit 151 is electrically connected to the first color-sharing pixel 111; the second driving circuit 152 is electrically connected to the second color-sharing pixel 112; and the third driving circuit 153 is electrically connected to the second color privacy pixel 122.

[0068] The display panel can be equipped with driving circuits 15 for the first color sharing pixel 111, the second color sharing pixel 112, and the second color privacy pixel 122, respectively. The driving circuit 15 includes a first driving circuit 151, a second driving circuit 152, and a third driving circuit 153. The first driving circuit 151 is electrically connected to the first color sharing pixel 111; the second driving circuit 152 is electrically connected to the second color sharing pixel 112; and the third driving circuit 153 is electrically connected to the second color privacy pixel 122, thereby improving control precision and ensuring the switching accuracy between the sharing mode and the privacy mode, as well as the display effect under different display modes.

[0069] Optional, Figure 19 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, such as... Figure 19 As shown, the second driving circuit 152 is electrically connected to the third color-shared pixel 113; the third driving circuit 153 is electrically connected to the third color privacy pixel 123.

[0070] Specifically, the second color-sharing pixel 112 and the third color-sharing pixel 113 need to be lit simultaneously in the sharing mode. In this mode, the second color-sharing pixel 112 and the third color-sharing pixel 113 can be electrically connected to the same driving circuit 15. Similarly, the second color privacy pixel 122 and the third color privacy pixel 123 need to be lit simultaneously in the privacy mode. In this mode, the second color privacy pixel 122 and the third color privacy pixel 123 can be electrically connected to the same driving circuit 15. This method reduces the number of driving circuits 15, improves the layout space of the driving circuits 15, and thus reduces electrical risks such as capacitance between adjacent driving circuits 15, image retention, and crosstalk.

[0071] Optional, continue to refer to Figure 13 The display panel also includes a color filter layer 16, which includes at least a third color filter layer 163. When the third color privacy pixel 123 and the third color shared pixel 113 are arranged adjacent to each other, the third color filter layer 163 covers at least the third color privacy pixel 123 and the third color shared pixel 113 along the thickness direction Z of the display panel.

[0072] The display panel also includes a color filter layer 16, which can improve the light purity of the emitted light. When the third color privacy pixel 123 and the third color shared pixel 113 are arranged adjacently, the third color filter layer 163 with the same color corresponding to the third color privacy pixel 123 and the third color shared pixel 113 can be prepared using the same process, so that along the thickness direction Z of the display panel, the third color filter layer 163 at least covers the third color privacy pixel 123 and the third color shared pixel 113, reducing the manufacturing difficulty and ensuring the light emission effect of the third color privacy pixel 123 and the third color shared pixel 113.

[0073] Optional, continue to refer to Figure 13 The color filter layer 16 also includes a first color filter layer 161 and a second color filter layer 162; the first color filter layer 161 and the second color filter layer are stacked on the surface of the third color filter layer 163 away from the third color privacy pixel 123; along the thickness direction Z of the display panel, the first color filter layer 161 and the second color filter layer 162 do not overlap with the third color privacy pixel 123, and do not overlap with the third color shared pixel 113.

[0074] The color filter layer 16 further includes a first color filter layer 161 and a second color filter layer 162. The first color filter layer 161 and the second color filter layer 162 are stacked on the third color filter layer 163. Along the thickness direction Z of the display panel, the first color filter layer 161 and the second color filter layer 162 do not overlap with the third color privacy pixel 123, and the first color filter layer 161 and the second color filter layer 162 do not overlap with the third color shared pixel 113. This can provide a light-blocking effect in the area where the third color privacy pixel 123 and the third color shared pixel 113 are located. The third color light at a large angle can be blocked by the first color filter layer 161 and the second color filter layer 162, avoiding the risk of light crosstalk and ensuring the display effect of the display panel in different display modes.
