The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Fig. 2 is a schematic structural diagram of a display panel according to an embodiment of the present invention, and as shown in fig. 2, the display panel 100 includes: a substrate base 10; a display function layer 20 located at one side of the substrate base plate 10; the display function layer 20 includes a plurality of pixels arranged in an array, each pixel including a plurality of sub-pixels having different emission colors; a light shielding layer 30 located on a side of the display function layer 20 facing away from the substrate 10; the light shielding layer 30 includes a plurality of opening portions 32 and a light shielding portion 31 surrounding each opening portion 32; the openings 32 cover the sub-pixels in a one-to-one correspondence in a direction perpendicular to the plane of the substrate 10.
Wherein the substrate 10 may be a flexible substrate or a rigid substrate; the flexible substrate can comprise PI or P flexible organic material layers, so that the substrate has the characteristic of being bendable and winding; the rigid substrate base may include a layer of hard inorganic material such as glass so that the substrate base has a sufficiently strong supporting ability.
The display function layer 20 is formed on one side of the substrate 10, and the display function layer 20 includes a plurality of pixels arranged in an array, each pixel includes a plurality of sub-pixels with different light emission colors, and each sub-pixel may include a light emitting element and a driving circuit, where the driving circuit is capable of driving the light emitting element to emit light. The driving circuit may include an active device and/or a passive device, where the active device includes a transistor, and the passive device includes a resistor, a capacitor, an inductor, and the like, and the specific structure of the driving circuit is not limited on the premise that the driving circuit can drive the light emitting element to perform display light emission.
In an exemplary embodiment, fig. 3 is a schematic view of a partial film structure of a display panel according to an embodiment of the present invention, and as shown in fig. 3, a transistor is used to represent a driving circuit S, where the display function layer 20 includes a semiconductor layer 24, a first metal layer 25, a second metal layer 26, an anode layer 27, a pixel defining layer 28, a cathode layer 29 and an encapsulation layer 201; the semiconductor layer 24 may include an active layer of a transistor, the first metal layer 25 includes a gate electrode of the transistor, etc., the second metal layer 26 includes a source electrode, a drain electrode of the transistor, etc., the anode layer 27 may include an anode of the light emitting element G, the cathode layer 29 includes a cathode of the light emitting element G, and the light emitting functional layer 210 of the light emitting element G may be disposed between the anode layer 27 and the cathode layer 29; the pixel defining layer 28 includes a pixel opening, and the light emitting functional layer 210 is located in the pixel opening, so that the pixel opening can define a light emitting area of the sub-pixel; the encapsulation layer 201 is at least located at one side of the cathode layer 29 facing away from the substrate 10, so that the encapsulation layer 201 can encapsulate each light emitting element G, and prevent water, mist or impurities in the outside air from entering the display panel, so as to protect the light emitting element G and ensure the service life of the display panel.
It should be noted that, in fig. 3, the structure of the display function layer of one sub-pixel is only illustrated by way of example, and when the display function layer provided in the embodiment of the present invention includes a plurality of sub-pixels, the description of the structure of the display function layer may be referred to in fig. 3, which is not repeated herein.
It will be appreciated that each pixel includes a plurality of sub-pixels with different emission colors, and the number and colors of the sub-pixels may be designed according to actual needs, which are not specifically limited herein. For example, the colors of the sub-pixels may include red, green, blue, yellow, white, and the like. For convenience of description, the embodiment of the present invention is exemplified by a pixel including a first sub-pixel, a second sub-pixel, and a third sub-pixel.
In addition, with continued reference to fig. 2, the display panel 100 further includes a light shielding layer 30 located on a side of the display function layer 20 facing away from the substrate 10; the light shielding layer 30 includes a plurality of opening portions 32 and a light shielding portion 31 surrounding each opening portion 32; the openings 32 cover the sub-pixels in a one-to-one correspondence in a direction perpendicular to the plane of the substrate 10.
The openings 32 are in one-to-one correspondence with the sub-pixels, so that the light emitted by each sub-pixel passes through the light shielding layer 30 and reaches the display surface of the display panel 100; since the light shielding part 31 surrounds the opening part 32 overlapped with each sub-pixel, the crosstalk between emergent rays of different sub-pixels is avoided, and the light emergent effect of the display panel is improved; the material of the light shielding portion 31 may include an acrylic resin doped with a black pigment (e.g., carbon), and is not particularly limited herein.
Optionally, with continued reference to fig. 2, the display panel 100 further includes a plurality of color resists 33 respectively located in the openings 32; in the color resist structure 33 and the sub-pixel which overlap in a direction perpendicular to the plane in which the substrate 10 is located, the emission color of the sub-pixel is the same as the light-transmitting color of the color resist structure 33. In this way, by disposing the color blocking structure 33 overlapping with the sub-pixel on the light emitting side of the sub-pixel, the light emitting color of the sub-pixel is the same as the light transmitting color of the color blocking structure 33, so that when the light emitted from the sub-pixel with the different light transmitting color from the color blocking structure 33 passes through the color blocking structure 33, the light with the different light transmitting color from the color blocking structure 33 can be blocked by the color blocking structure 33, and the light from the sub-pixel with the same light transmitting color as the color blocking structure 33 can be emitted to the light emitting side of the display panel 100 through the color blocking structure 33, so as to avoid the display crosstalk between the sub-pixels with different light emitting colors, enhance the color purity and contrast, and improve the light emitting effect. Meanwhile, the color resist structure 33 is disposed in the opening 32 of the light shielding layer 30, so that the color resist structure 33 is combined with the light shielding portion 31 to replace the polarizer, and compared with the polarizer, the combination mode makes the structure of the display panel 100 simple, and is beneficial to lightening and thinning of the display panel 100.
Accordingly, the light shielding portion 31 may cause a visual displacement of the viewer under a large viewing angle, and when the viewing angle is large to a certain extent, the light shielding portion 31 may shield the sub-pixels. As illustrated in fig. 2, the light shielding rate of each sub-pixel by the light shielding portion 31 at a positive viewing angle (for example, a viewing angle of 0 °) is smaller than the light shielding rate of each sub-pixel by the light shielding portion 31 at a non-positive viewing angle (for example, a viewing angle of 45 °). Because the light emitting areas of the sub-pixels are different, under a preset viewing angle, the light emitted by the sub-pixels with smaller light emitting areas has smaller shielding area or shielding amount, and can be perceived by human eyes, at this time, the shielding conditions of the light shielding portions on the sub-pixels with different light emitting areas under the preset viewing angle are different by adjusting the distance between the light shielding portions 31 and the sub-pixels, so that the light emitting light of the sub-pixels received under the preset viewing angle can be kept consistent, the color cast problem of the display panel is further improved, and the display effect of the display panel is improved.
Fig. 4 is a schematic top view of a display panel according to an embodiment of the invention, where, as shown in fig. 4, a plurality of sub-pixels at least includes a first sub-pixel 21, a second sub-pixel 22, and a third sub-pixel 23; at least part of the adjacent first sub-pixels 21 and second sub-pixels 22 are arranged along a first direction, and at least part of the adjacent second sub-pixels 22 and third sub-pixels 23 are arranged along a second direction; the light emitting areas of the first sub-pixel 21, the second sub-pixel 22, and the third sub-pixel 23 are different; in a direction perpendicular to a plane in which the substrate 10 is located, a light shielding portion overlapping a gap between the first sub-pixel 21 and the second sub-pixel 22 arranged and adjacent in the first direction is a first light shielding portion 311, and a light shielding portion overlapping a gap between the second sub-pixel 22 and the third sub-pixel 23 arranged and adjacent in the second direction is a second light shielding portion 312; the first sub-pixel 21 and the first light shielding portion 311 have a first pitch D1 in the first direction; the distance between the second sub-pixel 22 and the first light shielding portion 311 in the first direction is D2; the pitch of the second sub-pixel 22 and the second light shielding portion 312 in the second direction is a third pitch D3, and the pitch of the third sub-pixel 23 and the second light shielding portion 312 in the second direction is a fourth pitch D4; the width of the first light shielding portion 311 in the first direction is W1; the width of the second light shielding portion 312 in the second direction is W2; where d1 noteq D2, d3 noteq D4, w1=w2.
The colors of the first sub-pixel 21, the second sub-pixel 22 and the third sub-pixel 23 may be set according to actual needs, and the first sub-pixel 21 is taken as a red sub-pixel, the second sub-pixel 22 is taken as a green sub-pixel, and the third sub-pixel 23 is taken as a blue sub-pixel for illustration. The first direction and the second direction may be the same or different, and the following exemplary description will be given by taking the same example as the first direction and the second direction for convenience of description.
Specifically, the first sub-pixel 21, the second sub-pixel 22 and the third sub-pixel 23 respectively include light emitting elements of different colors, and materials of light emitting layers in the light emitting elements of different colors are different, so that the light emitting elements of different colors have different light emitting efficiencies, and when the sub-pixels have the same light emitting area, and the same driving signals such as the same driving current are applied to the light emitting elements of the sub-pixels, the light emitting brightness of the sub-pixel with higher light emitting efficiency is high; in order to enable all the sub-pixels to have the same luminous brightness under the same driving signals such as driving current, the luminous area of the sub-pixels with larger luminous efficiency can be reduced, the luminous area of the sub-pixels with smaller luminous efficiency is increased, and the sub-pixels with different luminous colors have different luminous areas; in addition, since the light emitted by the sub-pixels with larger light emitting area has larger luminous flux, the light emitted by the sub-pixels with smaller light emitting area has smaller luminous flux, when the shading part generates the same shading area or shading amount for the emitted light of each sub-pixel, the ratio of the part of light quantity of the sub-pixels with larger luminous flux to the part of light quantity of the sub-pixels with smaller luminous flux is smaller, and the ratio of the part of light quantity of the sub-pixels with smaller luminous flux to the part of light quantity of the sub-pixels with larger luminous flux is larger, so that the brightness of the light emitted by the sub-pixels with smaller luminous flux is obviously reduced under the preset angle, and the brightness of the light emitted by the sub-pixels with larger luminous flux is reduced, so that the color of a picture watched under the preset angle is different from the color of the picture watched under the front viewing angle, namely the color shift of the visual angle.
In order to balance the shielding effect of each shielding part on the light rays emitted by the sub-pixels with different light emitting areas under a preset viewing angle, the distances between the sub-pixels with different light emitting areas and the shielding part are different, namely, the first distance D1 between the first sub-pixel 21 and the first shielding part 311 in the first direction X is different from the second distance D2 between the second sub-pixel 22 and the first shielding part 311 in the first direction X, the third distance D3 between the second sub-pixel 22 and the second shielding part 312 in the second direction X is different from the fourth distance D4 between the third sub-pixel 23 and the second shielding part 312 in the second direction X, so that the shielding condition of the shielding part on the light rays emitted by the sub-pixels with different light emitting areas under the preset viewing angle is different, for example, the sub-pixels with small light flux can be provided with different distances between the sub-pixels with different light emitting areas and the first shielding part, the sub-pixels with smaller light emitting areas can be shielded by the second shielding part, the sub-pixels with smaller light emitting areas can be prevented from being received by the third sub-pixels with larger light flux, and the light rays can be prevented from being emitted by the second sub-pixels with larger light emitting areas; meanwhile, the widths of the first light shielding part 311 positioned between the first sub-pixel 21 and the second sub-pixel 22 and the second light shielding part 312 positioned between the second sub-pixel 22 and the third sub-pixel 23 are the same, so that the blocking capacity of the first light shielding part 311 and the second light shielding part 312 for light entering the display panel from the outside and reflected by the reflecting structure in the display panel is kept consistent, the widths of the light shielding parts at different positions are not required to be adjusted, the position of each light shielding part can be moved only in design to improve the visual character bias, the luminous flux of light reflected by the reflecting structure in the display panel is prevented from being influenced due to the increase of the width of the light shielding part, the light emitting rate of the display panel can be ensured, the display brightness of the display panel is improved, the display panel has higher display quantity without a larger driving signal, and the display power consumption is reduced.
It is to be understood that, on the premise that the first pitch D1 and the second pitch D2 are not equal, specific values may be set according to the light emitting area of the first sub-pixel 21, the light emitting area of the second sub-pixel 22, and the width W1 of the first light shielding portion 311, which are not particularly limited herein, and correspondingly, on the premise that the third pitch D3 and the fourth pitch D4 are not equal, specific values may be set according to the light emitting area of the second sub-pixel 22, the light emitting area of the third sub-pixel 23, and the width W2 of the second light shielding portion 312, which are not particularly limited herein.
Alternatively, referring to fig. 4, the light emitting area of the first sub-pixel 21 is smaller than the light emitting area of the second sub-pixel 22, D1> D2; and/or the light emitting area of the second sub-pixel 22 is smaller than the light emitting area of the third sub-pixel 23, D3> D4.
Specifically, when the distance between the sub-pixel and the light shielding part is larger, the size of the opening part overlapped with the sub-pixel is larger, so that the shielding area of the light shielding part for emitting light rays of the sub-pixel is smaller, and the transmittance of the light rays emitted by the sub-pixel in the light shielding layer 30 is larger, namely more light rays can be transmitted to the display surface of the display panel; in contrast, when the distance between the sub-pixel and the light shielding portion is smaller, the size of the opening portion overlapping the sub-pixel is smaller, so that the shielding area of the light emitted from the sub-pixel by the light shielding portion is larger, the transmittance of the light emitted from the sub-pixel in the light shielding layer 30 is smaller, that is, less light can be transmitted to the display surface of the display panel. In order to balance the shielding effect of the light shielding part on the emergent light of each sub-pixel, the distance between the sub-pixel with larger light emitting area and the light shielding part can be reduced, the distance between the sub-pixel with smaller light emitting area and the light shielding part is increased, the shielding area of the light shielding part on the sub-pixel with larger light emitting area is increased, the shielding area of the light shielding part on the sub-pixel with smaller light emitting area is reduced, namely when the light emitting area of the first sub-pixel 21 is smaller than the light emitting area of the second sub-pixel 22, and the light emitting area of the second sub-pixel 22 is smaller than the light emitting area of the third sub-pixel 23, the first distance D1 is larger than the second distance D2, and the third distance D3 is larger than the fourth distance D4, so that the ratio of the luminous flux of the first sub-pixel 21 shielded light to the luminous flux of the second sub-pixel 22 to the luminous flux of the emergent light is equal to or smaller than the ratio of the luminous flux of the second sub-pixel 22 to the luminous flux of the emergent light of the second sub-pixel, the ratio of the luminous flux of the second sub-pixel 22 to the luminous flux of the emergent light of the second sub-pixel is equal to the luminous flux of the third sub-pixel to the luminous flux of the emergent light under a preset viewing angle, and the preset viewing angle is kept equal to the luminous flux of the luminous flux to display panel is improved, and the problem is improved, and the display problem is better, under the display the problem is equal. Thus, the distance between each sub-pixel and the shading part is inversely related to the light emitting area of each sub-pixel, so that the light emitting brightness of different sub-pixels is consistent under a preset visual angle.
It is to be understood that the preset viewing angle may be any one of any non-positive viewing angles, for example, an upper left viewing angle of the display panel, an upper right viewing angle of the display panel, etc., and may be set according to actual needs, which is not specifically limited herein. On the premise that the first pitch D1 is larger than the second pitch D2 and the third pitch D3 is larger than the fourth pitch D4, specific values of the first pitch D1 and the second pitch D2 are related to light emitting areas of the first sub-pixel 21 and the second sub-pixel 22, specific values of the third pitch D3 and the fourth pitch D4 are related to light emitting areas of the second sub-pixel 22 and the third sub-pixel 23, and the arrangement can be performed according to actual needs without specific limitation.
Optionally, fig. 5 is a schematic top view of another display panel according to an embodiment of the present invention, as shown in fig. 5, at least part of the adjacent first sub-pixels 21 and third sub-pixels 23 in the display panel 100 are arranged along the third direction Y; the light shielding portion overlapping with the gap between the first sub-pixel 21 and the third sub-pixel 23 arranged and adjacent in the third direction Y in the direction perpendicular to the plane in which the substrate base plate 10 is located is a third light shielding portion 313; a pitch of the first sub-pixel 21 and the third light shielding portion 313 in the third direction Y is D5, and a pitch of the third sub-pixel 23 and the third light shielding portion 313 in the third direction Y is D6; the width of the third light shielding portion 313 in the third direction Y is W3; where w3=w1, d5+.d6.
Specifically, the first sub-pixel 21 and the third sub-pixel 23 have different light emitting areas, and because the luminous fluxes emitted by the sub-pixels with different light emitting areas are different, the emitted light brightness of the sub-pixels with different light emitting areas is different, and besides the color shift problem exists in the first direction and the second direction in the preset viewing angle, the color shift problem also exists in the third direction Y intersecting the first direction and the second direction, so that the shielding effect of each shielding part on the first sub-pixel 21 and the third sub-pixel 23 along the third direction Y is the same, the distance D5 between the first sub-pixel 21 and the third shielding part 313 in the third direction Y is different from the distance D6 between the third sub-pixel 23 and the third shielding part 313 in the third direction Y, and the shielding condition of the third shielding part 313 on the light of the first sub-pixel 21 and the third sub-pixel 23 with different light emitting areas is different in the preset viewing angle, so that the shielding condition of the light of the first sub-pixel 21 and the third sub-pixel 23 received in the preset viewing angle is balanced, the emitted light brightness can be kept consistent with the third sub-pixel 23, and the display brightness is improved, and the display effect is improved; meanwhile, by limiting the width W3 of the third light shielding portion 313 to be equal to the width W1 of the first light shielding portion 311, the blocking capability of the first light shielding portion 311 and the third light shielding portion 313 to light entering the display panel from the outside and reflected by the reflecting structure in the display panel is kept consistent, so that the width of the light shielding portions at different positions is not required to be adjusted, the position of each light shielding portion is only moved in design to improve the visual character bias, the luminous flux of light reflected by the reflecting structure in the display panel is prevented from being influenced by increasing the width of the light shielding portion, the light yield of the display panel is further ensured, the display brightness of the display panel is improved, the display panel has higher display quantity without larger driving signals, and the display power consumption is reduced.
The arrangement mode of each sub-pixel may be designed according to actual needs, for example, a part of the adjacent first sub-pixels 21 and third sub-pixels 23 are arranged along the third direction Y, and another part of the adjacent first sub-pixels 21 and third sub-pixels 23 are arranged along other directions different from the third direction Y; alternatively, all adjacent first sub-pixels 21 and third sub-pixels 23 are arranged along the third direction Y, which is not particularly limited in the embodiment of the present invention.
It is to be understood that, on the premise that the pitches D5 and D6 are not equal, specific values may be set according to the light emitting area of the first subpixel 21, the light emitting area of the third subpixel 23, and the width W3 of the third light shielding portion 313, which is not particularly limited herein.
Alternatively, the light emitting area of the first sub-pixel 21 is smaller than the light emitting area of the third sub-pixel 23; d5> D6.
Specifically, the light emitting area of the first sub-pixel 21 is smaller than the light emitting area of the third sub-pixel 23, so that the luminous flux of the light emitted from the first sub-pixel 21 is smaller than the luminous flux of the light emitted from the third sub-pixel 23. At this time, in order to balance the shielding effect of the third shielding portion 313 on the light emitted from the first sub-pixel 21 and the third sub-pixel 23, the space between the sub-pixel with a larger light emitting area and the shielding portion can be reduced, and the space between the sub-pixel with a smaller light emitting area and the shielding portion is increased, that is, the space D5 between the third sub-pixel 23 with a smaller light emitting area and the third shielding portion 313 is larger than the space D6 between the first sub-pixel 21 with a larger light emitting area and the third shielding portion 23, so that the shielding area of the third shielding portion 313 on the third sub-pixel 23 with a larger light emitting area is increased under a preset viewing angle, the shielding area of the third shielding portion 313 on the first sub-pixel 21 with a smaller light emitting area is reduced, and the ratio of the luminous flux of the first sub-pixel 21 with the light to the luminous flux of the light emitted from the third sub-pixel 23 can be equal to or smaller than the ratio of the luminous flux of the light emitted from the third sub-pixel 23 under the preset viewing angle, thereby enabling the received first sub-pixel 21 and the third sub-pixel 23 to maintain the consistent luminance display effect of the human eye under the preset viewing angle, and further improving the display luminance.
It is to be understood that, on the premise that the distance D5 is larger than the distance D6, specific values of the distance D5 and the distance D6 are related to the light emitting areas of the first sub-pixel 21 and the third sub-pixel 23, and may be set according to actual needs, which is not particularly limited herein.

Specifically, the first sub-pixel 21 and the second sub-pixel 22 have different light emitting areas, so that color shift problem is also caused by the different light emitting areas of the first sub-pixel 21 and the second sub-pixel 22 in the third direction Y under the preset viewing angle. In order to make the shielding effect of the fourth light shielding portion 314 on the first sub-pixel 21 and the second sub-pixel 22 along the third direction Y the same, the distance D7 between the first sub-pixel 21 and the fourth light shielding portion 314 in the third direction Y may be different from the distance D8 between the second sub-pixel 22 and the fourth light shielding portion 314 in the third direction Y, so that the shielding condition of the fourth light shielding portion 314 on the emergent light of the first sub-pixel 21 and the second sub-pixel 22 with different light emitting areas is different under the preset viewing angle, so as to balance the light emitted from each sub-pixel received under the preset viewing angle to keep consistent, thereby improving the color cast problem of the display panel and improving the display effect of the display panel; meanwhile, by limiting the width W4 of the fourth light shielding portion 314 to be equal to the width W1 of the first light shielding portion 311, the blocking capability of the first light shielding portion 311 and the fourth light shielding portion 314 to light entering the display panel from the outside and reflected by the reflecting structure in the display panel is kept consistent, so that the width of the light shielding portions at different positions is not required to be adjusted, the position of each light shielding portion is only moved in design to improve the visual character bias, the luminous flux of light reflected by the reflecting structure in the display panel is prevented from being influenced by increasing the width of the light shielding portion, the light yield of the display panel is further ensured, the display brightness of the display panel is improved, the display panel has higher display quantity without larger driving signals, and the display power consumption is reduced.
It is to be understood that, on the premise that the pitches D7 and D8 are not equal, specific values may be set according to the light emitting area of the first subpixel 21, the light emitting area of the second subpixel 22, and the width W4 of the fourth light shielding portion 314, which is not particularly limited herein.
Alternatively, the light emitting area of the first sub-pixel 21 is smaller than the light emitting area of the second sub-pixel 22; d7> D8.
