Detailed Implementation
[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0024] According to the first aspect of this application, Figures 1 to 9As shown, a display panel 1 is provided, including a substrate 10, a driving circuit layer 20, a light-emitting layer 30, and a light-shielding layer 40. The driving circuit layer 20 is disposed on one side of the substrate 10 and includes a plurality of light-transmitting patterns 20a. The light-emitting layer 30 is disposed on the side of the driving circuit layer 20 away from the substrate 10 and includes a plurality of light-emitting units 31, including privacy units 310 and non-privacy units 320. The light-shielding layer 40 is disposed on the side of the light-emitting layer 30 away from the substrate 10, exposing the light-emitting units 31. The light-shielding layer 40 includes a first light-shielding portion 41, a second light-shielding portion 42, and a third light-shielding portion 43. The second light-shielding portion 42 and the third light-shielding portion 43 are disposed in the same layer, and the first light-shielding portion 41 is located on the side of the third light-shielding portion 43 away from the substrate 10. The first light-shielding part 41 covers at least part of the third light-shielding part 43; the first light-shielding part 41 and the third light-shielding part 43 are located between two adjacent privacy units 310 along the first direction D1, and the second light-shielding part 42 is located between two adjacent non-privacy units 320 along the first direction D1. The distance s1 between the privacy unit 310 and the third light-shielding part 43 in the first direction D1 is less than the distance s2 between the non-privacy unit 320 and the second light-shielding part 42 in the first direction D1; wherein, in the second direction D2, the maximum distance s3 between the light-transmitting pattern 20a and the first light-shielding part 41 is greater than or equal to the maximum distance s5 between the light-transmitting pattern 20a and the third light-shielding part 43; the second direction D2 intersects the first direction D1, and both the second direction D2 and the first direction D1 are perpendicular to the thickness direction of the display panel 1.
[0025] like Figure 1 As shown, the display panel 1 includes a display area AA and a non-display area NA disposed around the periphery of the display area AA. The display area AA can be provided with multiple sub-pixels, which can include a first sub-pixel, a second sub-pixel, and a third sub-pixel of different emitting colors. The first, second, and third sub-pixels can be red, green, and blue sub-pixels respectively, thereby achieving color display. The display area AA is provided with a pixel driving circuit, which drives the sub-pixels for display. The non-display area NA can be provided with a gate driving circuit, etc., which provides driving signals to the sub-pixels.
[0026] In some embodiments, the substrate 10 can be a rigid material or a flexible material. The rigid material can be glass, quartz, or silicon. The flexible material can be one of polyimide (PI), polycarbonate (PC), polynorbornene (PNB), and polyethylene terephthalate (PET).
[0027] In some embodiments, the driving circuit layer 20 includes a plurality of thin-film transistors, capacitors, and signal lines arranged in an array; and the plurality of thin-film transistors, capacitors, and signal lines can be used to form a driving circuit for driving the display panel 1 to display, such as a gate driving circuit, a pixel driving circuit, etc.
[0028] The materials for thin-film transistors, capacitors, and signal lines can include metallic materials, such as any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or alloys thereof.
[0029] It should be noted that the display panel 1 also includes multiple insulating layers, which are disposed between two adjacent metal materials to achieve insulation between adjacent metal materials, etc.
[0030] like Figures 3A to 6 As shown, the driving circuit layer 20 includes multiple driving circuit patterns 23, and a light-transmitting pattern 20a is formed in the clearance area of the driving circuit patterns 23. The driving circuit layer 20 includes circuit structures such as thin-film transistors, capacitors, and signal lines, which form the driving circuit patterns 23. The light-transmitting pattern 20a refers to a pattern that allows light to pass through. When light shines on the driving circuit layer 20 along the thickness direction of the display panel 1, part of the light is blocked by the driving circuit patterns 23, while light can pass through the light-transmitting pattern 20a; that is, the area where light passes through forms the light-transmitting pattern 20a.
[0031] like Figure 6 As shown, no circuit structure is set in the light-transmitting pattern 20a. Therefore, the light-transmitting pattern 20a does not block light, meaning that light can pass through. In contrast, in areas where any of the following are set: thin-film transistors, capacitors, or signal lines, light is blocked by the metal material and cannot be allowed to pass through. The light-transmitting pattern 20a can increase the light transmittance of the display panel 1, allowing the sensor below the display panel 1 to receive ambient light, thereby realizing the sensing function.
[0032] In some embodiments, when the display panel 1 is an OLED panel, the light-emitting layer 30 may include a stacked anode, a light-emitting material layer, and a cathode. The anode provides holes, the cathode provides electrons, and the holes and electrons recombine in the light-emitting material layer to emit light.
[0033] In some embodiments, the display panel 1 further includes a pixel definition layer 50, which is provided with a plurality of pixel openings, and the light-emitting units 31 are provided corresponding to the pixel openings, with one pixel opening corresponding to one light-emitting unit 31.
[0034] like Figures 3A to 4As shown, the light-emitting layer 30 includes a plurality of light-emitting units 31. Each light-emitting unit 31 corresponds to a sub-pixel. The light-emitting units 31 may include red light-emitting units, green light-emitting units, and blue light-emitting units, thereby realizing color display.
[0035] Multiple light-emitting units 31 include a privacy unit 310 and a non-privacy unit 320. The privacy unit 310 can be used in a privacy display mode, and the non-privacy unit 320 can be used to implement a shared display mode. It should be noted that both the privacy unit 310 and the non-privacy unit 320 are light-emitting units 31, and the privacy unit 310 and the non-privacy unit 320 can be arranged in the same way. Through the spacing between the light-shielding layer 40 and the light-emitting unit 31 in the first direction D1, a portion of the light-emitting units 31 forms a privacy unit 310, while another portion forms a non-privacy unit 320.
[0036] One privacy unit 310 corresponds to one sub-pixel. Multiple privacy units 310 may include a first light-emitting unit 311, a second light-emitting unit 312, and a third light-emitting unit 313. Among them, the first light-emitting unit 311 can be a red light-emitting unit, the second light-emitting unit 312 can be a green light-emitting unit, and the third light-emitting unit 313 can be a blue light-emitting unit.
[0037] One non-spy unit 320 corresponds to one sub-pixel. Multiple non-spy units 320 may include a fourth light-emitting unit 321, a fifth light-emitting unit 322, and a sixth light-emitting unit 323. Among them, the fourth light-emitting unit 321 can be a red light-emitting unit, the fifth light-emitting unit 322 can be a green light-emitting unit, and the sixth light-emitting unit 323 can be a blue light-emitting unit.
[0038] like Figures 3A to 5 As shown, the light-shielding layer 40 is disposed on the side of the light-emitting layer 30 away from the substrate 10, and the light-shielding layer 40 is located on the light-emitting side of the light-emitting layer 30. The light-shielding layer 40 can block light. For example, the material of the light-shielding layer 40 can be a black material, such as black matrix, but it is not limited to this.
[0039] In some embodiments, the third light-shielding portion 43 and the second light-shielding portion 42 are disposed on the same layer. The third light-shielding portion 43 and the second light-shielding portion 42 may be formed using the same patterning process.
[0040] The first light-shielding portion 41 is located on the side of the third light-shielding portion 43 away from the substrate 10. Other film layers may be provided between the first light-shielding portion 41 and the third light-shielding portion 43. The first light-shielding portion 41 and the third light-shielding portion 43 at least partially overlap in the thickness direction of the display panel 1.
[0041] The distance s1 between the privacy unit 310 and the third light-shielding part 43 in the first direction D1 refers to the distance between the edges of the privacy unit 310 and the third light-shielding part 43 that are close to each other in the first direction D1. The distance s2 between the non-privacy unit 320 and the second light-shielding part 42 in the first direction D1 refers to the distance between the edges of the non-privacy unit 320 and the second light-shielding part 42 that are close to each other in the first direction D1.
[0042] Combination Figure 3B and Figure 4 Because the distance s1 between the privacy unit 310 and the third light-shielding part 43 in the first direction D1 is smaller than the distance s2 between the non-privacy unit 320 and the second light-shielding part 42 in the first direction D1, when the privacy unit 310 emits light, the distance s1 between the privacy unit 310 and the third light-shielding part 43 in the first direction D1 is smaller, and the third light-shielding part 43 can block the light from the privacy unit 310 at a wide viewing angle, thereby preventing others from observing the display screen from the side, thus realizing the privacy display mode. When the non-privacy unit 320 emits light, the distance s2 between the non-privacy unit 320 and the second light-shielding part 42 in the first direction D1 is larger, and it will not block the light from the non-privacy unit 320 at a wide viewing angle, thus allowing the display screen to be observed from a wide viewing angle, thereby realizing the shared display mode.
[0043] It should be understood that in privacy display mode, only privacy unit 310 can be illuminated. In shared display mode, both privacy unit 310 and non-privacy unit 320 can be illuminated simultaneously, or only non-privacy unit 320 can be illuminated.
[0044] The sensor can be used to automatically adjust the brightness of display panel 1 based on the ambient light level. For example... Figure 2 As shown, ambient light shines through the display panel 1 onto a sensor (not shown in the figure) located below the display panel 1 and is received by the sensor. Figure 2 Ambient light is indicated by an arrow. Field of View (FOV) represents the spatial angular range of light that the sensor can receive. FOV50 refers to the field of view corresponding to when the light intensity received by the sensor is 50% of the light intensity at the normal viewing angle (i.e., 0-degree viewing angle). For display products, especially mobile phones, the sensitivity of the sensor is controlled by FOV50 based on the requirement for automatic screen brightness adjustment. If the FOV50 angle is too small, the sensor sensitivity is low, resulting in poor adaptive dimming accuracy. If the FOV50 angle is too large, the sensor sensitivity is too high, causing the sensor to easily receive stray light from the outside world, which is also detrimental to the accuracy of the screen's adaptive dimming. Therefore, for display panel 1, FOV50 needs to be controlled within a suitable range; for example, FOV50 is usually controlled between 30 and 50 degrees.
[0045] In order to achieve the privacy display mode, the first light-shielding part 41 and the third light-shielding part 43 need to block the wide-angle light around the privacy unit 310. This will cause the light within a certain angle range around the light-transmitting pattern 20a to be blocked by the first light-shielding part 41 and the third light-shielding part 43, making it difficult for the sensor below the light-transmitting pattern 20a to receive the light, thus affecting the sensitivity of the sensor.
[0046] In response to this, such as Figure 3A and Figure 3B As shown in the embodiment of this application, in the second direction D2, the maximum distance s3 between the light-transmitting pattern 20a and the first light-shielding part 41 is greater than or equal to the maximum distance s5 between the light-transmitting pattern 20a and the third light-shielding part 43. Through this arrangement, the distance between the light-transmitting pattern 20a and the first light-shielding part 41 on one side can be increased, thereby reducing the obstruction of light near the light-transmitting pattern 20a by the first light-shielding part 41, and further reducing the influence of the light-shielding layer 40 on the light received by the sensor.
[0047] In some embodiments, such as Figures 7 to 9 As shown, in the second direction D2, the maximum distance s5 between the light-transmitting pattern 20a and the third light-blocking part 43 is less than the maximum distance s3 between the light-transmitting pattern 20a and the first light-blocking part 41. That is, the edge of the third light-blocking part 43 near the light-transmitting pattern 20a can extend beyond the edge of the first light-blocking part 41 near the light-transmitting pattern 20a.
[0048] Since the third light-shielding part 43 is closer to the light-emitting unit 31 in the thickness direction of the display panel 1 than the first light-shielding part 41, the third light-shielding part 43 has less impact on the light at the side viewing angle. Therefore, the third light-shielding part 43 can be closer to the light-transmitting pattern 20a than the first light-shielding part 41. In this way, the light at the side viewing angle of the light-transmitting pattern 20a can be reduced without excessively reducing it, while the privacy protection effect of the privacy unit 310 can be improved, resulting in less light leakage at a wide viewing angle.
[0049] In some embodiments, in the second direction D2, the maximum distance s5 between the light-transmitting pattern 20a and the third light-shielding portion 43 is equal to the maximum distance s3 between the light-transmitting pattern 20a and the first light-shielding portion 41. That is to say, the maximum distance between the first light-shielding portion 41 and the light-transmitting pattern 20a can be the same as the maximum distance between the third light-shielding portion 43 and the light-transmitting pattern 20a, thereby further reducing the obstruction of light from the side view of the light-transmitting pattern 20a by the third light-shielding portion 43.
[0050] In some embodiments, such as Figure 4 and Figure 5As shown, the display panel 1 also includes an encapsulation layer 60, which is disposed on the side of the light-emitting layer 30 away from the substrate 10. The encapsulation layer 60 can be formed by alternatingly stacked one or more organic encapsulation layers 62 and one or more inorganic encapsulation layers 61. For example, the organic encapsulation layer 62 can be a single layer or multiple layers formed of any one of polyethylene terephthalate, polyimide, polycarbonate, epoxy resin, polyethylene, and polyacrylate. The inorganic encapsulation layer 61 can be a single layer or multiple layers of metal oxide or metal nitride, such as silicon nitride, aluminum oxide, silicon oxide, etc.
[0051] In some embodiments, the display panel 1 further includes a touch electrode layer 70, which may be disposed between the encapsulation layer 60 and the light-shielding layer 40, and the touch electrode layer 70 may be used to implement touch functions.
[0052] In some embodiments, the display panel 1 further includes a first insulating layer 81 disposed on the touch electrode layer 70 near the substrate 10 and a second insulating layer 82 disposed on the touch electrode layer 70 away from the substrate 10.
[0053] In some embodiments, the display panel 1 further includes a third insulating layer 83 and a fourth insulating layer 84 disposed between the first light-shielding portion 41 and the second light-shielding portion 42.
[0054] In some embodiments, the display panel 1 further includes a fifth insulating layer 85 disposed on the first light-shielding portion 41 away from the substrate 10.
[0055] The first insulating layer 81, the second insulating layer 82, the third insulating layer 83, the fourth insulating layer 84, and the fifth insulating layer 85 can be inorganic or organic layers. For example, the inorganic layer can be a single or multiple layers of metal oxides or metal nitrides, such as silicon nitride, alumina, or silicon oxide. The organic layer can be a single or multiple layers formed from any one of polyethylene terephthalate, polyimide, polycarbonate, epoxy resin, polyethylene, and polyacrylate.
[0056] Optionally, such as Figure 3B As shown, the edge of the light-transmitting pattern 20a near the first light-blocking portion 41 is the first edge 21, and the edge of the light-transmitting pattern 20a near the second light-blocking portion 42 is the second edge 22; wherein, the extension direction of the outline of the first light-blocking portion 41 near the first edge 21 is at least partially the same as the extension direction of the first edge 21, and the extension direction of the outline of the second light-blocking portion 42 near the second edge 22 is at least partially the same as the extension direction of the second edge 22.
[0057] In some embodiments, the outline of the first edge 21 can be at least one of a straight line, a curve, etc. The outline of the second edge 22 can be at least one of a straight line, a curve, etc. That is to say, the outline of the first edge 21 and the outline of the second edge 22 can be a line segment, a polyline, a curve, or a combination of a straight line and a curve.
[0058] like Figure 3B As shown, a first light-blocking part 41 is provided on one side of the light-transmitting pattern 20a, and a second light-blocking part 42 is provided on the other side of the light-transmitting pattern 20a. The first light-blocking part 41 and the second light-blocking part 42 are arranged opposite to each other in the second direction D2.
[0059] like Figure 3B As shown, the extension direction of the outline of the first light-shielding portion 41 near the first edge 21 is at least partially the same as the extension direction of the first edge 21. This means that the outline of the first light-shielding portion 41 near the first edge 21 is at least partially and substantially the same as the outline of the first edge 21, i.e., at least partially and substantially parallel to the outline of the first edge 21. Through this arrangement, the distance between at least a portion of the first light-shielding portion 41 and the first edge 21 can be made similar, all greater than a certain fixed value, thereby reducing the obstruction of light near the first edge 21 by any position of the edge of the first light-shielding portion 41 and improving the sensitivity of the sensor.
[0060] The extension direction of the outline of the second light-shielding portion 42, which is close to the second edge 22, is at least partially the same as the extension direction of the second edge 22. That is, the outline of the second light-shielding portion 42 on the side close to the second edge 22 is at least partially and substantially the same as the outline of the second edge 22, meaning that the outline of the second light-shielding portion 42 on the side close to the second edge 22 is at least partially and substantially parallel to the outline of the second edge 22. Through this arrangement, the distance between at least a portion of the second light-shielding portion 42 and the second edge 22 can be similar, both exceeding a certain fixed value, thereby reducing the obstruction of light near the first edge 21 by any position of the edge of the second light-shielding portion 42 and improving the sensitivity of the sensor.
[0061] It should be understood that "approximately the same" refers to the sameness within the allowable range of process error.
[0062] In order to ensure that the first light-shielding part 41 does not affect the sensitivity of the sensor, the FOV50 of the sensor needs to be greater than or equal to 30 degrees.
[0063] In some embodiments, the maximum distance s3 between the light-transmitting pattern 20a and the first light-shielding portion 41 is greater than or equal to 6 micrometers. For example, s3 is 6 micrometers, 6.2 micrometers, 6.4 micrometers, 6.6 micrometers, 6.8 micrometers, 7 micrometers, 7.2 micrometers, 7.4 micrometers, 7.6 micrometers, 7.8 micrometers, 8 micrometers, etc.
[0064] In some embodiments, the maximum distance s4 between the light-transmitting pattern 20a and the second light-shielding portion 42 is also the distance between the second edge 22 and the second light-shielding portion 42 in the second direction D2. In the second direction D2, the distance between the second edge 22 and the second light-shielding portion 42 is greater than or equal to 6 micrometers. For example, the distance between the second edge 22 and the second light-shielding portion 42 is 6 micrometers, 6.2 micrometers, 6.4 micrometers, 6.6 micrometers, 6.8 micrometers, 7 micrometers, 7.2 micrometers, 7.4 micrometers, 7.6 micrometers, 7.8 micrometers, 8 micrometers, 8.2 micrometers, 8.4 micrometers, 8.6 micrometers, 8.8 micrometers, 9 micrometers, etc.
[0065] Optionally, such as Figure 3A and Figure 3B As shown, the privacy unit 310 and the non-privacy unit 320 are arranged alternately along the first direction D1, and the privacy unit 310 and the non-privacy unit 320 are arranged alternately along the second direction D2; wherein, the first light-blocking part 41 and the second light-blocking part 42 both extend along the second direction D2, and the maximum width w1 of the first light-blocking part 41 in the first direction D1 is greater than the maximum width w2 of the second light-blocking part 42 in the first direction D1.
[0066] The privacy screen unit 310 and the non-privacy screen unit 320 are arranged alternately along the first direction D1. That is to say, the privacy screen unit 310 and the non-privacy screen unit 320 are alternately arranged in the first direction D1. For example, a non-privacy screen unit 320 is provided between two adjacent privacy screen units 310 in the first direction D1, and a privacy screen unit 310 is provided between two adjacent non-privacy screen units 320 in the first direction D1.
[0067] The privacy screen unit 310 and the non-privacy screen unit 320 are arranged alternately along the second direction D2. That is to say, in the second direction D2, the privacy screen unit 310 and the non-privacy screen unit 320 are alternately arranged. For example, a non-privacy screen unit 320 is provided between two adjacent privacy screen units 310 in the second direction D2, and a privacy screen unit 310 is provided between two adjacent non-privacy screen units 320 in the second direction D2.
[0068] It should be noted that the alternation period can be set as needed, that is, at least one privacy screen unit 310 and at least one non-privacy screen unit 320 alternate. For example, the alternation period can be two, that is, one privacy screen unit 310 and one non-privacy screen unit 320 alternate. The alternation period can be greater than two, such as three, four, five, etc., that is, multiple privacy screen units 310 and multiple non-privacy screen units 320 alternate.
[0069] like Figure 3A and Figure 3BAs shown, the first light-shielding part 41 and the second light-shielding part 42 both extend along the second direction D2. That is to say, the long sides of the first light-shielding part 41 and the second light-shielding part 42 are both along the second direction D2, and the short sides of the first light-shielding part 41 and the second light-shielding part 42 are both along the first direction D1.
[0070] like Figure 3B As shown, the maximum width w1 of the first light-shielding part 41 in the first direction D1 is greater than the maximum width w2 of the second light-shielding part 42 in the first direction D1. With the above arrangement, the first light-shielding part 41 can be wider than the second light-shielding part 42, thereby blocking the light from the privacy unit 310 at a wide angle and achieving a privacy effect.
[0071] It should be noted that the first light-shielding part 41 may have an uneven width in the first direction D1, and the second light-shielding part 42 may have an uneven width in the first direction D1.
[0072] Optionally, such as Figure 3B As shown, the maximum width w3 of the light-transmitting pattern 20a in the first direction D1 is greater than the maximum width w2 of the second light-blocking part 42 in the first direction D1; the maximum width w3 of the light-transmitting pattern 20a in the first direction D1 is less than the maximum width w1 of the first light-blocking part 41 in the first direction D1.
[0073] In some embodiments, the maximum width w3 of the light-transmitting pattern 20a in the first direction D1 is greater than the maximum width w2 of the second light-blocking portion 42 in the first direction D1. This arrangement increases the maximum width w3 of the light-transmitting pattern 20a in the first direction D1, thereby allowing more light to pass through the light-transmitting pattern 20a.
[0074] In some embodiments, the light-transmitting pattern 20a may have an uneven width in the first direction D1.
[0075] In some embodiments, the maximum width w3 of the light-transmitting pattern 20a in the first direction D1 is smaller than the maximum width w1 of the first light-shielding part 41 in the first direction D1. This arrangement allows for a wider maximum width of the first light-shielding part 41, ensuring a privacy protection effect. This achieves a balance between privacy protection and light transmittance, ensuring privacy protection without affecting the sensor's sensitivity.
[0076] Optionally, such as Figure 3B As shown, in the direction close to the light-transmitting pattern 20a, the first light-blocking portion 41 extends beyond the adjacent privacy unit 310; in the direction close to the light-transmitting pattern 20a, the second light-blocking portion 42 extends beyond the adjacent non-privacy unit 320.
[0077] In some embodiments, such as Figure 3BAs shown, in the direction close to the light-transmitting pattern 20a, the first light-blocking portion 41 extends beyond the privacy unit 310. That is, for the first light-blocking portion 41 located above the light-transmitting pattern 20a, the lower end of the first light-blocking portion 41 extends beyond the lower edges of the adjacent privacy units 310 on both the left and right sides of the first light-blocking portion 41. For the first light-blocking portion 41 located below the light-transmitting pattern 20a, the upper end of the first light-blocking portion 41 extends beyond the upper edges of the adjacent privacy units 310 on both the left and right sides of the first light-blocking portion 41.
[0078] In some embodiments, such as Figure 3B As shown, in the direction near the light-transmitting pattern 20a, the second light-shielding portion 42 extends beyond the non-peeping unit 320. That is, for the second light-shielding portion 42 located above the light-transmitting pattern 20a, the lower end of the second light-shielding portion 42 extends beyond the lower edges of the adjacent non-peeping units 320 on both sides. For the second light-shielding portion 42 located below the light-transmitting pattern 20a, the upper end of the second light-shielding portion 42 extends beyond the upper edges of the adjacent non-peeping units 320 on both sides. With this arrangement, the risk of color shift in the light from the non-peeping unit 320 at a side view can be reduced, thereby improving white angular dependence (WAD). This is because if a certain color of light-emitting unit 31 in the non-peeping unit 320 is not blocked by the second light-shielding portion 42, the proportion of that color light will be higher at a side view, resulting in a color shift when viewed from the side.
[0079] Specifically, taking the non-peeping unit 320, which includes a red light-emitting unit, a green light-emitting unit, and a blue light-emitting unit, as an example, if the lower end of the second light-shielding part 42 does not extend beyond the lower edge of the red light-emitting unit and the lower edge of the blue light-emitting unit, but the second light-shielding part 42 extends beyond the green light-emitting unit, then from a side view, the green light emitted by the green light-emitting unit will be blocked by the second light-shielding part 42, while the red light emitted by the red light-emitting unit and the blue light emitted by the blue light-emitting unit will not be blocked by the second light-shielding part 42. This will result in a higher proportion of red and blue light from a side view, causing the white image to appear purplish from a side view, thus affecting the white angle dependence.
[0080] Optionally, such as Figure 3B , Figures 7 to 9 As shown, the extension direction of the outline of the first light-blocking portion 41, which is close to the light-transmitting pattern 20a, and the extension direction of the outline of the third light-blocking portion 43, which is close to the light-transmitting pattern 20a, are at least partially the same.
[0081] In some embodiments, such as Figure 7As shown, the extension direction of the outline of the first light-blocking portion 41, which is close to the light-transmitting pattern 20a, and the extension direction of the outline of the third light-blocking portion 43, which is also close to the light-transmitting pattern 20a, are partially the same. That is, the extension directions of the outlines of the edges of the first light-blocking portion 41 and the third light-blocking portion 43 near the light-transmitting pattern 20a are consistent. For example, when the outline of the edge of the first light-blocking portion 41 near the light-transmitting pattern 20a extends along the second direction D2, the outline of the edge of the third light-blocking portion 43 near the light-transmitting pattern 20a also extends along the second direction D2. When the outline of the edge of the first light-blocking portion 41 near the light-transmitting pattern 20a extends obliquely, the outline of the edge of the third light-blocking portion 43 near the light-transmitting pattern 20a also extends obliquely.
[0082] In some embodiments, such as Figure 3B As shown, the extension direction of the outline of the first light-blocking portion 41, which is close to the light-transmitting pattern 20a, and the extension direction of the outline of the third light-blocking portion 43, which is also close to the light-transmitting pattern 20a, are exactly the same. This means that the outlines of the first light-blocking portion 41 and the third light-blocking portion 43 near the light-transmitting pattern 20a coincide or are spaced at a fixed distance. In other words, the outline of the first light-blocking portion 41 near the light-transmitting pattern 20a can completely overlap with the outline of the third light-blocking portion 43 near the light-transmitting pattern 20a, or they can be offset by a certain distance.
[0083] In some embodiments, such as Figure 8 and Figure 9 As shown, the first edge 21 of the light-transmitting pattern 20a has a first portion extending along the second direction D2 and a second portion extending obliquely. Corresponding to the first edge 21, the partial outline of the edge of the first light-blocking portion 41 near the side of the light-transmitting pattern 20a can extend along the second direction D2, and the partial outline of the edge of the third light-blocking portion 43 near the side of the light-transmitting pattern 20a can maintain the same tilt angle as the second portion and extend obliquely.
[0084] Optionally, such as Figure 3B As shown, the edges of the first light-blocking portion 41 and the third light-blocking portion 43, which are close to the light-transmitting pattern 20a, coincide in the thickness direction of the display panel 1. This means that the edges of the first light-blocking portion 41 and the third light-transmitting portion near the light-transmitting pattern 20a completely overlap in the thickness direction of the display panel 1, i.e., the maximum distance between the edges of the first light-blocking portion 41 and the third light-transmitting portion near the light-transmitting pattern 20a in the second direction D2 is zero.
[0085] Optionally, such as Figures 7 to 9As shown, the edge of the third light-blocking portion 43, which is close to the light-transmitting pattern 20a, extends beyond the edge of the first light-blocking portion 41, which is close to the light-transmitting pattern 20a.
[0086] In some embodiments, such as Figures 7 to 9 As shown, in the second direction D2, the edge of the third light-shielding part 43 near the light-transmitting pattern 20a is at least partially located on the side of the first light-shielding part 41 near the light-transmitting pattern 20a.
[0087] In some embodiments, such as Figure 7 As shown, the edge of the third light-shielding portion 43 near the light-transmitting pattern 20a can be a straight line extending along the second direction D2, and the edge of the first light-shielding portion 41 near the light-transmitting pattern 20a can be a straight line extending along the second direction D2 and a straight line extending obliquely. In other words, the first light-shielding portion 41 can be provided with a chamfer, and at the chamfer, the third light-shielding portion 43 is not provided with a chamfer, so that the third light-shielding portion 43 extends beyond the first light-shielding portion 41.
[0088] In some embodiments, such as Figure 8 and Figure 9 As shown, the first light-shielding part 41 may be provided with a chamfer. At the chamfer, the chamfer shape of the third light-shielding part 43 is different from the chamfer shape of the first light-shielding part 41, so that the third light-shielding part 43 extends beyond the first light-shielding part 41.
[0089] Optionally, such as Figure 5 and Figure 9 As shown, the display panel 1 also includes a touch electrode layer 70 disposed between the light-emitting layer 30 and the light-shielding layer 40. The touch electrode layer 70 includes a first electrode line 71 extending along a first direction D1 and a second electrode line 72 extending along a second direction D2. The first electrode line 71 and the second electrode line 72 are intersected and connected to form a grid structure, wherein the extension direction of the outline of the first light-shielding portion 41 close to the light-transmitting pattern 20a and the extension direction of the outline of the grid structure close to the light-transmitting pattern 20a are at least partially the same.
[0090] In the second direction D2, the first electrode line 71 is disposed between two adjacent light-emitting units 31. A portion of the first electrode line 71 is disposed between two adjacent privacy units 310, a portion of the first electrode line 71 is disposed between two adjacent non-privacy units 320, and a portion of the first electrode line 71 is disposed between adjacent privacy units 310 and non-privacy units 320.
[0091] In the first direction D1, the second electrode line 72 is disposed between two adjacent light-emitting units 31. A portion of the second electrode line 72 is disposed between two adjacent privacy units 310, a portion of the second electrode line 72 is disposed between two adjacent non-privacy units 320, and a portion of the second electrode line 72 is disposed between adjacent privacy units 310 and non-privacy units 320.
[0092] In some embodiments, the outline of the first light-shielding portion 41 near the edge of the light-transmitting pattern 20a in the second direction D2 may be parallel to the outline of the lower edge of the first electrode line 71, and the outline of the first light-shielding portion 41 near the edge of the light-transmitting pattern 20a in the first direction D1 may be parallel to the outline of the right edge of the second electrode line 72.
[0093] Optionally, such as Figure 9 As shown, the first light-shielding part 41 is flush with the edge of the light-transmitting pattern 20a in the second direction D2, and the first electrode line 71 is flush with the edge of the light-transmitting pattern 20a; the first light-shielding part 41 is flush with the edge of the light-transmitting pattern 20a in the first direction D1, and the second electrode line 72 is flush with the edge of the light-transmitting pattern 20a.
[0094] In some embodiments, such as Figure 9 As shown, the edge of the first light-shielding part 41 near the light-transmitting pattern 20a in the second direction D2 can be flush with the lower edge of the first electrode line 71, and the edge of the first light-shielding part 41 near the light-transmitting pattern 20a in the first direction D1 can be flush with the right edge of the second electrode line 72, so that the first light-shielding part 41 at least blocks part of the first electrode line 71 and part of the second electrode line 72, reducing the reflection of ambient light by the touch electrode layer 70.
[0095] In some embodiments, such as Figure 9 As shown, the edge of the third light-shielding part 43 near the light-transmitting pattern 20a can extend beyond the lower edge of the first electrode and the right edge of the second electrode line 72, thereby reducing the risk of light leakage at a wide viewing angle.
[0096] In some embodiments, such as Figure 9 As shown, in the second direction D2, the second light-shielding part 42 can be connected to the third light-shielding part 43, thereby further reducing the risk of light leakage at a wide viewing angle.
[0097] In other embodiments, such as Figure 3B and Figure 7 As shown, in the second direction D2, the second light-shielding part 42 can be disconnected from the third light-shielding part 43, thereby reducing the obstruction of light near the light-transmitting pattern 20a by the second light-shielding part 42 and the third light-shielding part 43.
[0098] In other embodiments, such as Figure 8As shown, in the second direction D2, a portion of the second light-shielding part 42 can be connected to the third light-shielding part 43 to further reduce the risk of light leakage at a large viewing angle; another portion of the second light-shielding part 42 can be disconnected from the third light-shielding part 43 to reduce the obstruction of light near the light-transmitting pattern 20a by the second light-shielding part 42 and the third light-shielding part 43.
[0099] Optionally, such as Figure 3A and Figure 7 As shown, the light-shielding layer 40 also includes a fourth light-shielding part 44 and a fifth light-shielding part 45 located between the privacy unit 310 and the non-privacy unit 320 adjacent along the first direction D1. The fourth light-shielding part 44 is disposed in the same layer as the second light-shielding part 42, and the fifth light-shielding part 45 is disposed in the same layer as the first light-shielding part 41. The fifth light-shielding part 45 and the fourth light-shielding part 44 at least partially overlap. Among them, two fourth light-shielding parts 44 adjacent along the second direction D2 are connected and disposed, and two fifth light-shielding parts 45 adjacent along the second direction D2 are connected and disposed. The light-transmitting pattern 20a is located between two fourth light-shielding parts 44 adjacent along the first direction D1.
[0100] In some embodiments, such as Figure 3A and Figure 7 As shown, the fourth light-shielding part 44 is located between the privacy unit 310 and the non-privacy unit 320 adjacent to each other along the second direction D2. In other words, the left side of the fourth light-shielding part 44 is adjacent to the privacy unit 310, and the right side of the fourth light-shielding part 44 is adjacent to the non-privacy unit 320. The distance between the fourth light-shielding part 44 and the privacy unit 310 in the first direction D1 is smaller than the distance between the fourth light-shielding part 44 and the non-privacy unit 320 in the first direction D1, thereby enabling the privacy unit 310 to achieve a privacy display mode, and the non-privacy unit 320 to achieve a shared display mode.
[0101] In some embodiments, the maximum width of the fourth light-shielding portion 44 and the fifth light-shielding portion 45 in the first direction D1 may be the same.
[0102] In some embodiments, the fourth light-shielding portion 44 and the fifth light-shielding portion 45 may completely overlap or partially overlap.
[0103] In other embodiments, such as Figure 3A As shown, the maximum widths of the fourth light-shielding part 44 and the fifth light-shielding part 45 in the first direction D1 can be different, and the width of the fourth light-shielding part 44 in the first direction D1 can be greater than the width of the fifth light-shielding part 45 in the first direction D1.
[0104] In some embodiments, such as Figure 3A and Figure 7As shown, two adjacent fourth light-shielding parts 44 are connected along the second direction D2, which means that two adjacent fourth light-shielding parts 44 can be continuously arranged in the second direction D2.
[0105] In some embodiments, such as Figure 3A and Figure 7 As shown, two adjacent fifth light-shielding parts 45 are connected along the second direction D2, which means that two adjacent fifth light-shielding parts 45 can be continuously arranged in the second direction D2.
[0106] Optionally, the distance s6 between the light-transmitting pattern 20a and the fourth light-shielding part 44 in the first direction D1 is greater than the distance between the light-transmitting pattern 20a and the first light-shielding part 41 in the second direction D2. This means that the larger distance between the fourth light-shielding part 44 and the light-transmitting pattern 20a in the first direction D1 reduces the obstruction of light from the side viewpoint of the light-transmitting pattern 20a by the fourth light-shielding part 44 in the first direction D1. The smaller distance between the first light-shielding part 41 in the second direction D2 allows the first light-shielding part 41 to be as close as possible to the light-transmitting pattern 20a, thus ensuring the privacy protection effect of the privacy unit 310.
[0107] The distance between the light-transmitting pattern 20a and the first light-blocking part 41 in the second direction D2 is the maximum distance s3 between the light-transmitting pattern 20a and the first light-blocking part 41.
[0108] In some embodiments, such as Figure 3B As shown, the light-transmitting pattern 20a does not overlap with any of the light-emitting units 31 in the first direction D1, thereby preventing the light-transmitting pattern 20a from occupying the space of the first light-shielding part 41 or the second light-shielding part 42. In other words, if the light-transmitting pattern 20a is set to coincide with the light-emitting unit 31 in the first direction D1, the light-shielding layer 40 cannot be set at the light-transmitting pattern 20a, and thus cannot achieve the privacy protection effect.
[0109] like Figure 10 As shown, a comparison diagram of simulation results for the field of view angles of two embodiments of this application is presented. Embodiment 1 is... Figure 3A The embodiments in the example, embodiment 2 is Figure 7 The embodiments are shown in the figure. The difference between Embodiment 2 and Embodiment 1 is that the edges of the first light-shielding part 41 and the third light-shielding part 43 near the light-transmitting pattern 20a in Embodiment 1 completely overlap and are both provided with chamfers. The first light-shielding part 41 in Embodiment 2 is the same as the first light-shielding part 41 in Embodiment 1. The only difference between Embodiment 2 and Embodiment 1 is that the third light-shielding part 43 is not provided with chamfers.
[0110] like Figure 10As shown, the horizontal axis represents the field of view (FOV), and the vertical axis represents the percentage of light intensity. A vertical axis of 100% represents the direct viewing angle (0°). With the light intensity set to 100%, the FOV50 corresponds to a field of view of 30 to 50 degrees for the sensor. FOV50 refers to the field of view when the light intensity received by the sensor is 50% of the light intensity at 0 degrees. FOV50 corresponds to... Figure 10 Data when the vertical axis is 50%.
[0111] Based on the simulation results, such as Figure 11 As shown, the FOV50 corresponding to Example 1 has a V+ of 34.5 degrees and a V- of 31.2 degrees. The FOV50 corresponding to Example 2 has a V+ of 33.2 degrees and a V- of 30.7 degrees. In Example 1, the green light-emitting unit in the privacy unit 310 has a light leakage of 0.8% at a 60-degree side viewing angle and 1.2% at a 75-degree side viewing angle. In Example 2, the green light-emitting unit in the privacy unit 310 has a light leakage of 0.8% at a 60-degree side viewing angle and 0.7% at a 75-degree side viewing angle. This means that Example 2 has less light leakage at a 75-degree side viewing angle, resulting in a better improvement in light leakage control.
[0112] Therefore, Example 1 has a better improvement effect on FOV50 than Example 2, and Example 2 has a better improvement effect on light leakage at a large viewing angle than Example 1.
