Description

Technical Field

[0002] OLED (Organic Light Emitting Diode) display panels have high clarity and wide viewing angle, which can generally reach 170 degrees, giving users a better visual experience. However, users sometimes also hope that the viewing angle of the display panel can be adjusted to a smaller size to effectively protect commercial secrets and personal privacy.

[0003] In order to achieve anti-peeping, the pixel units of some display panels include display pixels and anti-peeping pixels, and a shading structure is set above the anti-peeping pixels. In normal mode, the anti-peeping pixels are turned off and the display panel can display normally; in anti-peeping mode, the anti-peeping pixels are turned on, and the shading structure blocks the small-angle light of the anti-peeping pixels. The large-angle light of the anti-peeping pixels is not blocked, which can interfere with the display of the display pixels. In other words, in anti-peeping mode, the display image within the anti-peeping viewing angle is not disturbed, and the display image outside the anti-peeping viewing angle will be disturbed, thereby achieving large-angle anti-peeping.

[0031] Embodiment 1 See also Figures 1 to 3 As shown, in this embodiment, the display panel 10 includes a base substrate 100, a driving circuit layer 200, an anode 310, a pixel definition layer 320, a light emitting layer 330, a cathode layer 340, an encapsulation layer 400 and a light shielding unit 510. The driving circuit layer 200 is arranged on one side of the base substrate 100, and the base substrate 100 includes a glass substrate, a polyimide (Pi) substrate, etc. The driving circuit layer 200 includes a plurality of pixel driving circuits. A plurality of anodes 310 are formed on the side of the driving circuit layer 200 away from the base substrate 100, and each anode 310 can be connected to a pixel driving circuit.

[0032] The pixel definition layer 320 is formed on the side of the driving circuit layer 200 away from the base substrate 100, and the pixel definition layer 320 includes a plurality of pixel opening areas 322 and a pixel definition portion 321 surrounding the pixel opening area 322, that is, the pixel definition portion 321 defines the pixel opening area 322, the pixel definition portion 321 covers the edge area of ​​the anode 310, and the pixel opening area 322 exposes the central area of ​​the anode 310.

[0033] The light-emitting layer 330 is formed at least in the pixel opening area 322, and the light-emitting layer 330 is connected to the anode 310. The light-emitting layer 330 includes a plurality of display light-emitting parts 331 and a plurality of anti-peeping light-emitting parts 332, that is, the display light-emitting parts 331 and the anti-peeping light-emitting parts 332 are both arranged in the pixel opening area 322, each display light-emitting part 331 is connected to an anode 310, each anti-peeping light-emitting part 332 is connected to an anode 310, and the anodes 310 corresponding to the anti-peeping light-emitting parts 332 can be connected. In some embodiments, the light-emitting layer 330 also includes a non-light-emitting part on the pixel definition part 321 outside the pixel opening area 322, and the display light-emitting part 331 and the anti-peeping light-emitting part 332 are both connected to the non-light-emitting part, which can be determined according to the specific situation. The cathode layer 340 is formed on the side of the pixel definition layer 320 and the light-emitting layer 330 away from the base substrate 100.

[0034] The encapsulation layer 400 is formed on the side of the cathode layer 340 away from the base substrate 100, and the encapsulation layer 400 may include a first inorganic encapsulation layer 410, an organic encapsulation layer 420, and a second inorganic encapsulation layer 430 formed in sequence. The shading unit 510 is formed on the side of the encapsulation layer 400 away from the base substrate 100, and the shading unit 510 is arranged in a one-to-one correspondence with the anti-peeping light-emitting portion 332. At least part of the edge of the shading unit 510 is an arc edge, and the arc includes a circular arc or an elliptical arc. The shading unit 510 can be made of a metal material or a black organic material. The orthographic projection of the display light-emitting portion 331 on the base substrate 100 is spaced from the orthographic projection of the shading unit 510 on the base substrate 100, and the orthographic projection of the anti-peeping light-emitting portion 332 on the base substrate 100 is located within the orthographic projection of the shading unit 510 on the base substrate 100.

[0035] The display mode of the display panel 10 includes a normal mode and an anti-peeping mode. In the anti-peeping mode, both the display light emitting unit 331 and the anti-peeping light emitting unit 332 emit light, and the shading unit 510 blocks the small-angle light output of the anti-peeping light emitting unit 332. The large-angle light of the anti-peeping light emitting unit 332 is not blocked, which can interfere with the display of the display light emitting unit 331 to achieve large-angle anti-peeping; in the normal mode, the anti-peeping light emitting unit 332 does not emit light, the display light emitting unit 331 emits light normally, and the display panel 10 can display normally. That is to say, in the anti-peeping mode, the display image within the anti-peeping angle a (usually around 25°) is not disturbed, and the display image outside the anti-peeping angle a will be disturbed, thereby achieving large-angle anti-peeping.

[0036] In some technical solutions, when the display panel 10 displays an image in the anti-peeping mode, the user can also see part of the anti-peeping light-emitting portion 332 within the anti-peeping angle a, that is, the light of the anti-peeping light-emitting portion 332 that is not expected to appear within the anti-peeping angle a interferes with the light of the display light-emitting portion 331, affecting the display effect of the display panel 10 within the anti-peeping angle a. The anti-peeping angle a is determined by the shading angle of the shading unit 510. The larger the shading range of the shading unit 510, the larger the anti-peeping angle a. The applicant has found that the user can also see part of the anti-peeping light-emitting portion 332 within the anti-peeping angle a because part of the anti-peeping light continues to propagate by bypassing the shading unit 510 that serves as an obstacle.

[0037] In this embodiment, the display panel 10 includes a base substrate 100, a driving circuit layer 200, a pixel definition layer 320, a light-emitting layer 330, an encapsulation layer 400 and a shading unit 510. The driving circuit layer 200 is arranged on one side of the base substrate 100, a plurality of anodes 310 are formed on the side of the driving circuit layer 200 away from the base substrate 100, the pixel definition layer 320 is formed on the side of the driving circuit layer 200 away from the base substrate 100, the pixel definition layer 320 is formed on the side of the driving circuit layer 200 away from the base substrate 100, the pixel definition layer 320 includes a plurality of pixel opening areas 322 and a pixel definition portion 321 surrounding the pixel opening area 322, the light-emitting layer 330 is formed in the pixel opening area 322, the light-emitting layer 330 includes a plurality of display light-emitting portions 331 and a plurality of anti-peep light-emitting portions 332, the encapsulation layer 400 is formed on the side of the pixel definition layer 320 and the light-emitting layer 330 away from the base substrate 100, the shading unit 510 is formed on the side of the encapsulation layer 400 away from the base substrate 100, and at least part of the edge of the shading unit 510 is an arc edge. At least part of the edge of the shading unit 510 is an arc-shaped edge, which can reduce the intensity of the diffracted light, reduce or eliminate the unwanted anti-peeping light within the anti-peeping viewing angle in the anti-peeping mode, and improve the display effect of the display panel 10 within the anti-peeping viewing angle.

[0038] In some embodiments, the display panel 10 further includes a conductor portion 610 and an eave portion 620, wherein the conductor portion 610 is formed on the side of the pixel definition portion 321 away from the base substrate 100, and the eave portion 620 is formed on the side of the conductor portion 610 away from the base substrate 100. The eave portion 620 protrudes relative to the conductor portion 610, so that a recessed area is formed between the eave portion 620 and the pixel definition portion 321, and the recessed area is located on both sides of the conductor portion 610 opposite to the pixel opening area 322. The light emitting layer 330 and the cathode layer 340 are both formed by evaporation, the eave portion 620 is used to separate the light emitting layer 330, and the conductor portion 610 is used to connect the cathode layer 340.

[0039] It should be noted that the display panel 10 may include a conductor portion 610 and an eaves portion 620 for forming the structure of the light-emitting layer 330 and the cathode layer 340, but is not limited thereto. The light-emitting layer 330 may also be evaporated using a high-precision metal mask (Fine Metal Mask, FMM), and the cathode layer 340 entirely covers the pixel definition layer 320 and the light-emitting layer 330, depending on the specific situation.

[0040] As the resolution of the display panel 10 increases, a high-precision metal mask is used to evaporate the light-emitting layer 330. The production cost of the high-precision metal mask is high, and it is difficult to achieve high-precision mesh technology and evaporation alignment technology. The display panel 10 includes a conductor part 610 and an eaves part 620, which are used to form the structure of the light-emitting layer 330 and the cathode layer 340. A high-precision metal mask is not required, which is conducive to reducing process difficulty and process cost.

[0041] In some embodiments, the shading unit 510 includes a main body 511 and an auxiliary shading portion 512, and the auxiliary shading portion 512 is located on the side of the main body 511 away from the base substrate 100. The orthographic projection of the anti-peeping light emitting portion 332 on the base substrate 100 is located within the orthographic projection of the main body 511 on the base substrate 100, and the orthographic projection of the main body 511 on the base substrate 100 is located within the orthographic projection of the auxiliary shading portion 512 on the base substrate 100. The main body 511 is used to limit the light emitting angle of the anti-peeping light emitting portion 332 to form an anti-peeping angle a, and the auxiliary shading portion 512 is used to block the diffracted light within the anti-peeping angle a.

[0042] The auxiliary shading portion 512 blocks the diffracted light within the anti-peeping viewing angle a, further reducing or eliminating the undesired anti-peeping light within the anti-peeping viewing angle in the anti-peeping mode, and improving the display effect of the display panel 10 within the anti-peeping viewing angle.

[0043] In some embodiments, the orthographic projection of the shading unit 510 on the base substrate 100 is a circle, an ellipse or a rounded polygon, and the rounded polygon is, for example, a rounded rectangle, a rounded regular hexagon, a rounded regular octagon, and a rounded regular decagon, etc. The main body 511 and the auxiliary shading portion 512 have the same or substantially the same shape, and the orthographic projections of the main body 511 and the auxiliary shading portion 512 on the base substrate 100 are correspondingly a circle, an ellipse or a rounded polygon.

[0044] The orthographic projection of the shading unit 510 on the base substrate 100 is a circle, an ellipse or a rounded polygon, which can further reduce the intensity of the diffracted light and reduce or eliminate the undesired anti-peeping light within the anti-peeping angle in the anti-peeping mode.

[0045] In some embodiments, the orthographic projection of the anti-peeping light-emitting portion 332 on the base substrate 100 and the orthographic projection of the light-shielding unit 510 on the base substrate 100 have the same shape but different sizes.

[0046] The orthographic projection of the anti-peeping light emitting portion 332 on the base substrate 100 is the same as the orthographic projection of the light shielding unit 510 on the base substrate 100 , and the anti-peeping viewing angles a at different viewing angles are the same, which can improve the display effect of the display panel 10 .

[0047] In some embodiments, the plurality of display light-emitting portions 331 include a first light-emitting portion 3311, a second light-emitting portion 3312, and a third light-emitting portion 3313, the light-emitting efficiency of the first light-emitting portion 3311 is greater than the light-emitting efficiency of the second light-emitting portion 3312, and the light-emitting efficiency of the second light-emitting portion 3312 is greater than the light-emitting efficiency of the third light-emitting portion 3313. For example, the first light-emitting portion 3311 may emit green light, the second light-emitting portion 3312 may emit red light, and the third light-emitting portion 3313 may emit blue light. The display panel 10 includes a plurality of pixel units, and the pixel unit includes at least one first light-emitting portion 3311, at least one second light-emitting portion 3312, and at least one third light-emitting portion 3313.

[0048] The first light-emitting portion 3311 and the second light-emitting portion 3312 are arranged at intervals along the first direction. The first light-emitting portion 3311 and the second light-emitting portion 3312 are located on one side of the third light-emitting portion 3313 in the second direction, and the second direction is perpendicular to the first direction. The first direction is, for example, a row direction, and the second direction is, for example, a column direction. In the first direction, the first light-emitting portion 3311 and the second light-emitting portion 3312 are aligned with the third light-emitting portion 3313 as a whole. For example Figure 3 As shown, the distance between the left side of the first light-emitting portion 3311 and the left side of the third light-emitting portion 3313 is equal to the distance between the right side of the second light-emitting portion 3312 and the right side of the third light-emitting portion 3313. The anti-peeping light-emitting portion 332 corresponds to the pixel unit one by one and is arranged at the junction of adjacent display light-emitting portions 331. The extension line of the junction line of adjacent display light-emitting portions 331 passes through the anti-peeping light-emitting portion 332, and the adjacent side of the display light-emitting portion 331 adjacent to the anti-peeping light-emitting portion 332 is an arc side.

[0049] The anti-peeping light-emitting portion 332 is disposed at the junction of adjacent display light-emitting portions 331 , which can prevent the anti-peeping light-emitting portion 332 from occupying too large an area of ​​a display light-emitting portion 331 and affecting the display effect of the display panel 10 .

[0050] In addition, since the shape of the anti-peeping light emitting portion 332 is different from the shape of the pixel unit, the size of the anti-peeping light emitting portion 332 is also different from the size of the pixel unit. If the anti-peeping light emitting portion 332 is set outside the pixel unit, it will lead to waste of design space of the display panel 10, affecting the aperture ratio and pixel density of the display panel 10. In the present application, the anti-peeping light emitting portion 332 is set at the junction of adjacent display light emitting portions 331, that is, the anti-peeping light emitting portion 332 is correspondingly set in each pixel unit, which solves the arrangement problem of the anti-peeping light emitting portion 332 and the pixel unit, avoids waste of design space of the display panel 10, and improves the aperture ratio and pixel density of the display panel 10.

[0051] In some embodiments, the anti-peeping light emitting portion 332 is disposed at the junction of the first light emitting portion 3311, the second light emitting portion 3312, and the third light emitting portion 3313. Figure 4 shown.

[0052] The anti-peeping light emitting portion 332 is disposed at the junction of the three display light emitting portions 331 . The anti-peeping light emitting portion 332 does not occupy too much area of ​​each display light emitting portion 331 , thereby improving the display effect of the display panel 10 .

[0053] In some embodiments, the anti-peeping light emitting portion 332 is located at the junction of the first light emitting portion 3311 and the second light emitting portion 3312. Figure 3 The adjacent sides of the first light emitting portion 3311 and the anti-peeping light emitting portion 332 are arc-shaped sides, and the adjacent sides of the second light emitting portion 3312 and the anti-peeping light emitting portion 332 are arc-shaped sides.

[0054] The third light emitting unit 3313 has the lowest luminous efficiency and usually occupies the largest area. The anti-peeping light emitting unit 332 is arranged at the junction of the first light emitting unit 3311 and the second light emitting unit 3312, and does not occupy the design space of the third light emitting unit 3313 with the lowest luminous efficiency, which is conducive to improving the brightness and life of the third light emitting unit 3313.

[0055] It should be noted that the anti-peeping light-emitting portion 332 may be disposed at the junction of the first light-emitting portion 3311, the second light-emitting portion 3312 and the third light-emitting portion 3313 or at the junction of the first light-emitting portion 3311 and the second light-emitting portion 3312, but is not limited thereto. The anti-peeping light-emitting portion 332 may also be disposed at the junction of the second light-emitting portion 3312 and the third light-emitting portion 3313, such as Figure 5 As shown, it depends on the specific situation.

[0056] In some embodiments, the anti-peeping light-emitting portion 332 is made of the same material as the first light-emitting portion 3311 , and the light-emitting color of the anti-peeping light-emitting portion 332 is the same as the light-emitting color of the first light-emitting portion 3311 .

[0057] The first light-emitting portion 3311 has the highest luminous efficiency and the maximum brightness under the same data voltage. The luminous color of the anti-peeping light-emitting portion 332 is the same as that of the first light-emitting portion 3311. The anti-peeping light-emitting portion 332 occupies a smaller area and has the smallest impact on the resolution of the display panel 10.

[0058] It should be noted that the luminous color of the anti-peeping luminous unit 332 may be the same as the luminous color of the first luminous unit 3311, but is not limited thereto. The luminous color of the anti-peeping luminous unit 332 may also be the same as the luminous color of the second luminous unit 3312, depending on the specific situation. In some embodiments, the luminous color of the anti-peeping luminous unit 332 may also be the same as the luminous color of the third luminous unit 3313.

[0059] Since the anti-peeping light-emitting portion 332 does not emit light in the normal mode, when the ratio of the area occupied by the anti-peeping light-emitting portion 332 to the area occupied by the first light-emitting portion 3311 is large, the brightness difference between the first light-emitting portion 3311 and the anti-peeping light-emitting portion 332 is obvious, which has a great impact on the display effect of the display panel 10. The light color of the anti-peeping light-emitting portion 332 is the same as the light color of the second brightest display light-emitting portion 331 (i.e., the second light-emitting portion 3312), which can reduce the brightness difference between the anti-peeping light-emitting portion 332 and the second light-emitting portion 3312, and reduce the impact on the display effect of the display panel 10.

[0060] In some embodiments, the anti-peeping light-emitting portion 332 includes materials for making at least any two of the first light-emitting portion 3311, the second light-emitting portion 3312, and the third light-emitting portion 3313, and the anti-peeping light-emitting portion 332 is a stack of two or three organic light-emitting materials. For example, the anti-peeping light-emitting portion 332 includes materials for making the first light-emitting portion 3311 and materials for making the second light-emitting portion 3312, and the light-emitting color of the anti-peeping light-emitting portion 332 is yellow; the anti-peeping light-emitting portion 332 includes materials for making the first light-emitting portion 3311, materials for making the second light-emitting portion 3312, and materials for making the third light-emitting portion 3313, and the light-emitting color of the anti-peeping light-emitting portion 332 is white.

[0061] The anti-peeping light emitting portion 332 emits yellow or white light. The anti-peeping light emitting portion 332 has a greater brightness, and the anti-peeping light and the display light are more likely to form a visual contrast, thereby improving the anti-peeping effect.

[0062] In some embodiments, the display panel 10 further includes a color resist layer 520, which is formed on the side of the encapsulation layer 400 away from the base substrate 100, and the orthographic projection of the display light-emitting portion 331 on the base substrate 100 is located within the orthographic projection of the color resist layer 520 on the base substrate 100. The color resist layer 520 may include green color resist, red color resist and blue color resist arranged at intervals, the green color resist and the first light-emitting portion 3311 are arranged one-to-one, the red color resist and the second light-emitting portion 3312 are arranged one-to-one, and the blue color resist and the third light-emitting portion 3313 are arranged one-to-one. The display panel 10 further includes a black matrix, which is formed on the side of the encapsulation layer 400 away from the base substrate 100 and is located in the surrounding area of ​​the green color resist, the red color resist and the blue color resist. A light-emitting gap is formed between the light-shielding unit 510, the color resist layer 520 and the black matrix, and the light-emitting gap surrounds the light-shielding unit 510, and a transparent organic filling layer 530 may be arranged in the light-emitting gap.

[0063] In order to improve the contrast of the display panel 10 and achieve an integrated black effect, the display panel 10 usually uses a polarizer (POL), which can effectively reduce the reflection intensity of the external ambient light on the screen. However, the light transmittance of the polarizer is generally only about 44%. In order to achieve a higher light output brightness, more power consumption is required. In addition, the polarizer is thick and brittle, which is not conducive to the development of dynamic bending products.

[0064] The display panel 10 includes a color resist layer 520, which can block external light and filter the light emitted by the display light-emitting portion 331, thereby reducing the reflection intensity of the external ambient light on the screen. The polarizer of the display panel 10 can be eliminated, which not only greatly reduces the thickness of the display panel 10, but also can increase the light output rate from 44% to 80%, thereby greatly increasing the light output brightness, thereby reducing the power consumption of the display panel 10.

[0065] Embodiment 2 The main difference between the second embodiment and the first embodiment is that the positional relationship between the anti-peeping light emitting portion 332 and the pixel unit is different.

[0066] See also Figure 6 As shown, the plurality of display light-emitting portions 331 include a first light-emitting portion 3311, a second light-emitting portion 3312, and a third light-emitting portion 3313. The display panel 10 includes a plurality of pixel units, and the pixel unit includes at least one first light-emitting portion 3311, at least one second light-emitting portion 3312, and at least one third light-emitting portion 3313. The second light-emitting portion 3312, the first light-emitting portion 3311, and the third light-emitting portion 3313 are sequentially arranged at intervals along a first direction, and the first direction is, for example, a row direction, or vice versa.

[0067] The anti-peeping light-emitting portion 332 is disposed at the junction of at least some of the four adjacent pixel units. That is, the anti-peeping light-emitting portion 332 is disposed at the junction of some of the four adjacent pixel units, and the anti-peeping light-emitting portion 332 may not be disposed at the junction of some of the four adjacent pixel units. For example, 1, 2 or 3 anti-peeping light-emitting portions 332 are disposed corresponding to every 4 pixel units. In addition, the anti-peeping light-emitting portion 332 may also be disposed at the junction of every four adjacent pixel units, and the ratio of the pixel unit to the anti-peeping light-emitting portion 332 is approximately 1:1. The extension line of the boundary line of adjacent pixel units passes through the anti-peeping light-emitting portion 332, and the adjacent side of the display light-emitting portion 331 adjacent to the anti-peeping light-emitting portion 332 is an arc side.

[0068] The anti-peeping light emitting portion 332 is disposed at the junction of four adjacent pixel units. The anti-peeping light emitting portion 332 does not occupy too large an area of ​​each pixel unit and each display light emitting portion 331 , thereby improving the display effect of the display panel 10 .

[0069] In some embodiments, the luminous efficiency of the first light emitting unit 3311 is greater than that of the second light emitting unit 3312, and the luminous efficiency of the second light emitting unit 3312 is greater than that of the third light emitting unit 3313. For example, the first light emitting unit 3311 may emit green light, the second light emitting unit 3312 may emit red light, and the third light emitting unit 3313 may emit blue light. That is, the anti-peeping light emitting unit 332 is disposed between the two second brightest display light emitting units 331.

[0070] The anti-peeping light-emitting portion 332 is disposed between the two second-brightest display light-emitting portions 331 , which can reduce the brightness difference between the anti-peeping light-emitting portion 332 and the display light-emitting portion 331 , thereby reducing the impact on the display effect of the display panel 10 .
