It should be noted that the partial cross-sectional view of the display panel shown in fig. 2 refers to a cross-sectional view perpendicular to the plane of the display panel 100, and similar parts in the following embodiments are not repeated.

Alternatively, the base substrate 110 may be a flexible base substrate or a rigid base substrate. The flexible substrate may be a polyimide resin, a metal film, or the like, and the rigid substrate may be a glass substrate.

Optionally, the array layer 120 is located on one side of the substrate base plate 110. Specifically, the array layer 120 includes devices such as a driving circuit, for example, a thin film transistor, a capacitor, a trace, and the like, for electrically connecting the light emitting elements 130 and driving the light emitting elements to emit light. The embodiment of the invention takes a top gate as an example to describe the array layer 120 in detail.

Optionally, as shown in fig. 2, the array layer 120 includes a buffer layer 121, an active layer 122, a gate insulating layer 123, a gate layer 124, an interlayer dielectric layer 125, a source/drain electrode 126, a passivation layer 127, and a conductive layer 128 electrically connected to the light emitting element 130, which are sequentially stacked along a direction away from the substrate 110. In detail, the active layer 122 is disposed on the buffer layer 121, and the material of the active layer 122 may be Indium Gallium Zinc Oxide (IGZO), which may make the thin film transistor in a transparent and flexible state; the gate insulating layer 123 is positioned on the active layer 122; the gate layer 124 is disposed on the gate insulating layer 123; the interlayer dielectric layer 125 covers the gate layer 124, the interlayer dielectric layer 125 may be a single-layer structure or a multi-layer stacked structure, in this embodiment, the interlayer dielectric layer 125 is a double-layer structure, such as a silicon nitride/silicon oxide stacked layer; the source and drain electrodes 126 are disposed on the interlayer dielectric layer 125, and the source and drain electrodes 126 are connected to the active layer 122 through via holes; the passivation layer 127 covers the source and drain electrodes 126 and the interlayer dielectric layer 125 to realize film planarization, and the passivation layer 127 can be made of silicon nitride or silicon oxide; optionally, the light emitting element 130 is a micro light emitting diode, and the conductive layer 128 is a sensing electrode. It should be noted that the phrase "one layer is located on" another layer in this paragraph means that one layer is located on the side of the other layer away from the substrate 110. In some embodiments of the present invention, as shown in fig. 3, fig. 3 is a partial cross-sectional view of another display panel according to the embodiments of the present invention. The display panel 100 further includes spacers 140 positioned between the adjacent light emitting elements 130. Alternatively, as shown in fig. 3, the spacer 140 has a thickness gradually decreasing in a direction in which the second base 160 points to the substrate base 110, and the thickness refers to a width in a direction in which the first light emitting element 131 points to the second light emitting element 132.

In some embodiments of the present invention, as shown in fig. 3, the second substrate 160 may also be a color filter substrate. The second substrate 160 further includes a black matrix layer 161 and a color-resisting layer 162, the black matrix layer 161 is located at an end of the spacer 140 away from the substrate 110, and the color-resisting units of the color-resisting layer 162 are located between the black matrix units of the black matrix layer 161. The black matrix is generally made of a material having a high light-shielding property, and serves to prevent light rays emitted from adjacent pixels from crosstalk with each other, thereby improving contrast between the pixels; the material of the color resistance layer 162 may be at least one or more of pigment, light-curable resin, alkali-soluble resin, and photoinitiator of corresponding color. Optionally, the material of the first color resist layer 150 may be at least one or more of pigments, light-curable resins, alkali-soluble resins, and photoinitiators of corresponding colors, and the purpose of the mixture is to achieve a light filtering function, and the color resist has high or low transmittance and good color saturation, depending on the size of the pigment dispersion particles and the concentration of the added additives, and has heat resistance, light resistance, and chemical resistance.

In some embodiments of the present invention, as shown in fig. 2, the height of the first color resist layer 150 is consistent with the height of the light emitting element 130 along the direction perpendicular to the plane of the substrate base plate 110. It should be noted that the first color resist layer 150 is located between the first substrate 160 and the array layer 120, and the light emitting element 130 is also located between the first substrate 160 and the array layer 120, and the same height refers to the same starting point and ending point on the same reference line, the reference line refers to one end of the array layer 120 far away from the substrate base plate 110, if the light emitting element 130 is a micro light emitting diode, the light emitting element 130 is located on one side of the sensing electrode 128 far away from the substrate base plate 110, and then the starting point of the light emitting element 130 is the side of the sensing electrode 128 close to the array layer 120. With such an arrangement, the light emitted from the side of the light emitting element 130 can be blocked by the color resistor as much as possible.

The embodiment of the invention reduces the light crosstalk of at least one side of the light-emitting element to the adjacent light-emitting element by arranging the color resistance between the adjacent light-emitting elements, and also reduces the height of the spacer or does not need the spacer, thereby simplifying the process. Meanwhile, because the side light of most of the light-emitting elements is filtered by the color resistors, the spacer on the side of the color resistor away from the substrate does not need to be very thick, and only the buffer effect when the array substrate and the color film substrate are covered is needed to be played, so that the light-emitting elements are protected from being impacted, the aperture opening ratio of pixels is greatly reserved, the light extraction efficiency is improved, and the power consumption of the display panel is reduced.

Referring to fig. 4, fig. 4 is a partial cross-sectional view of another display panel according to an embodiment of the invention. The same parts as those in the above embodiments are not repeated, and the difference between the embodiments of the present invention is that the first color resist layer 150 at least includes a first color resist unit 151 and a second color resist unit 152, the first color resist unit 151 and the second color resist unit 152 have different colors, and the first color resist unit 151 and the second color resist unit 152 are sequentially disposed along the direction of the first light emitting element 131 pointing to the second light emitting element 132. The first color resistance unit 151 and the second color resistance unit 152 have different colors. Optionally, the first color resistance unit 151 and the first light emitting element 131 have the same color, and the second color resistance unit 152 and the second light emitting element 132 have the same color, so that the first light L1 (solid line in fig. 4) emitted from the first light emitting element 131 is blocked by the second color resistance unit 152 having a different color from the first color resistance unit 151 after passing through the first color resistance unit 151, and cannot enter the adjacent light emitting unit; compared with the spacer 140 only disposed between the adjacent light emitting elements 130, because the thickness of the spacer 140 near the array layer 120 is small, it is difficult to block the crosstalk of the light reflected by the metal in the array layer 120 to the adjacent light emitting units, and in the embodiment, after the second light L2 (the dotted line in fig. 4) exits from the first light emitting element 131, the second color blocking unit 152, which is reflected by the metal in the array layer 120 to a color different from that of the first color blocking unit 151, is blocked, so that the crosstalk of the light of the adjacent light emitting elements is further reduced.

In the embodiment of the invention, the color resistances with different colors are arranged between the adjacent light-emitting elements, so that the interference of the light emitted from the bottom surface of the light-emitting element on the adjacent light-emitting units after being reflected by the metal of the array layer is reduced while the light crosstalk of the adjacent light-emitting units caused by the poor blocking performance of the spacer is reduced, the height of the spacer is further reduced, the cost of the process is reduced, and the preparation of the spacer is simpler.

Referring to fig. 5, fig. 5 is a partial cross-sectional view of another display panel according to an embodiment of the invention. The first color resist layer 150 has only one color, and the first color resist layer 150 is different from the first light emitting element 131 and the second light emitting element 132.

In the embodiment of the invention, the color resistors with different colors from the adjacent light-emitting elements are arranged between the adjacent light-emitting elements, so that the light crosstalk between the adjacent light-emitting units can be reduced only by arranging one color resistor, and the process is simpler and more convenient.

Referring to fig. 6, fig. 6 is a partial cross-sectional view of another display panel according to an embodiment of the invention. The display panel 100 further includes main color resist layers 170 disposed at intervals on a side of the light emitting element 130 away from the substrate 110, the main color resist layers 170 and the light emitting elements 130 are disposed in a one-to-one correspondence to form the light emitting units 200, in at least one of the light emitting units 200, the main color resist layers 170 and the light emitting elements 130 have the same color, the main color resist layers 170 cover top surfaces of the light emitting elements 130, and the top surfaces of the light emitting elements 130 are surfaces away from the substrate 110.

The main color resistance layer 170 is arranged on the side of the light emitting element 130 far away from the substrate base plate 110, the light emitted from the top of the light emitting element 130 is directly filtered by the main color resistance layer 170, and the light is emitted in a purer state, so that the process of manufacturing a color film layer on the second base plate 160 is omitted, the main color resistance layer 170 is manufactured by using materials such as light-cured resin, alkali soluble resin and the like, the materials such as light-cured resin, alkali soluble resin and the like have certain compressive strength, when the array base plate (comprising the array layer 120 and the substrate base plate 110) and the second base plate 160 are covered, the main color resistance layer 170 can play a compressive role, the impact on the light emitting element 130 is reduced, and therefore, no spacer is required to be arranged between adjacent light emitting units in the embodiment of the invention.

In the embodiment of the invention, the top surface of the light-emitting element is coated with the color resistor, the main color resistor layer can filter crosstalk light without manufacturing an additional color film layer to filter light, and the color resistor material has certain buffering capacity and can replace a spacer to play a buffering role when the array substrate and another substrate arranged opposite to the array substrate are covered, so that the arrangement of the spacer between the light-emitting units is omitted, and the cost is further saved.

Referring to fig. 7, fig. 7 is a partial cross-sectional view of another display panel according to an embodiment of the invention. The display panel 100 further includes main color resists 170 spaced apart from each other on a side of the light emitting elements 130 away from the substrate 110, the main color resists 170 and the light emitting elements 130 are disposed in a one-to-one correspondence to form the light emitting units 200, in at least one of the light emitting units 200, the main color resist 170 has the same color as the light emitting elements 130, the main color resist 170 covers top and side surfaces of the light emitting elements 130, the top surface of the light emitting element 130 is a surface away from the substrate 110, the side surface of the light emitting element 130 is a surface facing an adjacent light emitting unit 200, and the first color resist 150 includes a side surface portion of the light emitting element 130 covered by the main color resist 170.

The main color resist layer 170 covers the top surface of the light emitting element 130, the light emitting element 130 is emitted after passing through the main color resist layer 170 of the same color, the emitted light is purer, a color film layer is not required to be continuously manufactured on the second substrate 160 for filtering, important materials of the main color resist layer 170, such as light-cured resin, alkali soluble resin and the like, have certain compressive strength, when the array substrate (including the array layer 120 and the substrate 110) and the second substrate 160 are covered, the main color resist layer 170 can play a compressive role, the top surface and the side surface of the light emitting element 130 are wrapped, the light emitting element 130 is protected from impact, and no spacer is required to be arranged between adjacent light emitting units in the embodiment of the invention. Meanwhile, the main color resist layer 170 covers the side surface of the light emitting element 130, so that light on the side surface of the first light emitting element 131 can pass through the first main color resist layer 171 having the same color as the first light emitting element 131, but cannot pass through the adjacent second main color resist layer 172 having a different color, and thus light emission of the second light emitting element 132 cannot be interfered, and crosstalk of light is reduced.

In the embodiment of the invention, the top surface and the side surface of the light-emitting element are coated with the color resistors, the main color resistor layer can filter crosstalk light without additionally manufacturing a color film layer to filter light, and the color resistor material has certain compressive strength to coat the light-emitting element, so that the light-emitting element can be protected when the display panel falls or is impacted, the arrangement of the spacers between the light-emitting units is saved, the cost is further saved, more space for placing the light-emitting element is saved due to no limitation of the spacers, and enough space is reserved for manufacturing the main color resistor layer on the side surface of the light-emitting element, so that the light is more difficult to interfere with the adjacent light-emitting element. And because the adjacent main color resistance layers on the first light-emitting element and the second light-emitting element have different colors, the light of the first light-emitting element cannot penetrate through the main color resistance layer coated on the side surface of the second light-emitting element, and therefore the crosstalk of the light is also reduced.

Referring to fig. 8, fig. 8 is a partial cross-sectional view of another display panel according to an embodiment of the invention. The first color resist layer 150 further includes a third color resist unit 153, and the third color resist unit 153 has different colors from the main color resist layers 170 of the two adjacent light emitting units 200.

The main color resist layer 170 covers the top and side surfaces of the light emitting device 130, and the color resist 155 on the side surface is relatively thin, so that part of the light may still penetrate the color resist 155 on the side surface, and the bottom light of the first light emitting device 131 may also directly enter the adjacent second light emitting device 132 after being reflected by the metal in the array layer 120.

Optionally, the third color-resisting unit 153 is located between the first light emitting element 131 and the second light emitting element 132, and a side away from the array layer 120 contacts with a side of the light emitting element 130 close to the array layer 120, so that the third color-resisting unit 153 plays a role of buffering when the light emitting element 130 is transferred.

Optionally, the third color-resisting unit 153 contacts the adjacent light emitting element 130.

Optionally, the height of the third color-resisting unit 153 is blocked to the side of the light-emitting element 130 away from the array layer 120, that is, in the direction perpendicular to the plane of the substrate 110, the side of the third color-resisting unit 153 away from the substrate 110 is flush with the side of the light-emitting element 130 away from the substrate 110.

In the embodiment of the invention, by arranging the monochromatic color resistors (the third color resistor units 153) with different colors from the light-emitting units between the adjacent light-emitting units, light can be blocked by the third color resistor units after penetrating through the color resistors on the side surfaces of the light-emitting elements, so that the possibility that the light enters the adjacent light-emitting elements through the color resistors on the side surfaces is further reduced; secondly, the third color-resisting unit also blocks the bottom light of the light-emitting element reflected by the metal of the array layer from entering the adjacent light-emitting element.

Referring to fig. 9, fig. 9 is a partial cross-sectional view of another display panel according to an embodiment of the invention. The first color resist layer 150 further includes a first color resist unit 151 and a second color resist unit 152, the first color resist unit 151 and the second color resist unit 152 have different colors, and the first color resist unit 151 and the second color resist unit 152 are sequentially disposed along a direction perpendicular to the plane of the substrate 110.

In the embodiment of the present invention, since the two color resistors with different colors are sequentially disposed in the direction perpendicular to the plane of the substrate 110, the external light L3 is blocked by the overlapped color resistors and is difficult to continue to enter the display panel 100.

Referring to fig. 10, fig. 10 is a partial cross-sectional view of another display panel according to an embodiment of the invention. At least a portion of the first color resist layer 150 is integrally formed with at least a portion of the primary color resist layer 170.

Specifically, the first color resist layer 150 further includes a first color resist unit 151 and a second color resist unit 152, the first color resist unit 151 and the second color resist unit 152 are respectively formed by extending the main color resist layer 170 of the corresponding adjacent light emitting units 200, and the first color resist unit 151 and the second color resist unit 152 are sequentially disposed along a direction perpendicular to the plane of the substrate 110.

Optionally, the first color resistance unit 151 is formed by extending a first main color resistance layer 171 covering the first light emitting element 131, and the second color resistance unit 152 is formed by extending a second main color resistance layer 172 covering the second light emitting element 132, that is, the first color resistance unit 151 and the first main color resistance layer 171 are integrally formed by using the same material and the same process, and the second color resistance unit 152 and the second main color resistance layer 172 are integrally formed by using the same material and the same process, so that steps and cost of the process are reduced.

Optionally, if the light emitting element 130 is a micro light emitting diode, the main color resistance layer 170 may extend to a partial region of one side of the sensing electrode 128 far from the substrate base plate 110, so that the micro light emitting diode can play a role in buffering when being transferred to the display panel 100, and the pins of the micro light emitting diode are not easily damaged.

Optionally, the side color resists of the main color resist layer 170 extend to the array layer 120 along a direction perpendicular to the substrate base plate 110 without a gap from the array layer 120, so as to prevent the second light L2 emitted from the bottom of the light emitting element 130 from entering the adjacent light emitting unit 200 through the gap after being reflected by the metal in the array layer 120.

Optionally, there is no gap between the first color resistance unit 151 and the second color resistance unit 152.

In the embodiment of the invention, the first color resist layer and the main color resist layer are integrally formed, that is, in the process, the color resist units in the first color resist layer are all extended from the main color resist layer, so that the process and the cost of the process are reduced, and meanwhile, even though light emitted from the bottom of the light-emitting element is reflected by metal in the array layer, the light cannot enter the adjacent light-emitting unit through a gap between the first color resist layer and the substrate, so that the possibility of light crosstalk is reduced.

Referring to fig. 11 and 12, fig. 11 is a partial cross-sectional view of another display panel according to an embodiment of the invention, and fig. 12 is a partial cross-sectional view of another display panel according to an embodiment of the invention. The first color resist layer 150 further includes a third color resist unit 153, the third color resist unit 153 is located at one side far away from the substrate base plate 110 and is sequentially disposed along a direction perpendicular to the plane of the substrate base plate 110 with the first color resist unit 151 and the second color resist unit 152, and the third color resist unit 153 and the main color resist layers 170 in the two adjacent light emitting units 200 are different in color.

Optionally, on a plane parallel to the plane of the substrate base plate 110, an edge of the third color-resisting unit 153 away from the substrate base plate 110 is flush with an edge of the adjacent light-emitting element 130 away from the substrate base plate 110.

The first color resist layer 150 includes a first color resist unit 151 and a second color resist unit 152 sequentially disposed along a plane perpendicular to the substrate 110, and a third color resist unit 153 sequentially disposed on a side away from the substrate 110 and with the two color resist units, wherein the first color resist layer 150 is disposed between the adjacent light emitting elements 130, so that the side light of the light emitting elements 130 received by one end of the first color resist layer 150 away from the substrate 110 is the most, and if the light is filled with the color resist having the same color as the light emitting elements 130, the light may still penetrate through the color resist and enter the adjacent light emitting elements, and therefore, the above problem may be solved as much as possible by using the third color resist units 153 having different colors from the main color resist layer 170 in the two adjacent light emitting elements 200.

In the embodiment of the invention, the first color resistance layer formed by sequentially overlapping the three color resistances with different colors can prevent external light from entering the display panel through the gap between the adjacent light-emitting elements and reduce the crosstalk of the side light and the bottom light of the light-emitting elements to the adjacent light-emitting elements.

Further, referring to fig. 10 or fig. 11, the first main color resist layer 172 extends to the array layer 120 except between the adjacent first light emitting element 131 and the second light emitting element 132, and the first main color resist layer 172 completely covers the second light emitting element 132 between the array layer 120 and the second substrate 160.

Referring to fig. 13, fig. 13 is a partial cross-sectional view of another display panel according to an embodiment of the invention. The first color resistance layer 150 includes a first color resistance unit 151, a second color resistance unit 152, and a third color resistance unit 153, the second color resistance unit 152 covers the top surface and the side surface of the first color resistance unit 151, the third color resistance unit 153 covers the top surface and the side surface of the second color resistance unit 152, the top surface of the first color resistance unit 151 and the top surface of the second color resistance unit 152 are both surfaces far away from the substrate 110, and the side surface of the first color resistance unit 151 and the side surface of the second color resistance unit 152 are both surfaces facing the adjacent light emitting elements 130.

Optionally, the third color-resisting unit 153 is different from the adjacent light emitting elements 130.

In the prior art, the spacer 140 is usually prepared by using the second substrate 160 as a substrate, so that under the etching effect of the spacer 140 in the process, after the two substrates are aligned and attached, the spacer often has an inverted trapezoid shape in which a portion close to the second substrate 160 is thick and a portion close to the array layer 120 is thin, which means that light emitted by the light emitting element 130 on the array layer 120 easily penetrates through the thin portion of the spacer 140 and enters an adjacent light emitting element, so it is important to increase the thickness of the barrier layer on the side of the light emitting element 130, but the thickness of the spacer 140 is thick, which is not favorable for the pixel aperture ratio.

In the embodiment of the invention, the second color resistance unit is used for coating the first color resistance unit, and the third color resistance unit is used for coating the second color resistance unit, so that on one hand, the light blocking layer on the side surface of the light-emitting element is thicker, light hardly penetrates through the blocking layer, on the other hand, the pixel aperture ratio is also kept, the light extraction efficiency is improved, and the power consumption of the panel is reduced.
