Description

Technical Field

[0001] This disclosure relates to the field of display panel technology, and more specifically, to a display panel and a display device. Background Technology

[0002] Display panels are an indispensable component of electronic devices such as mobile phones and computers, and include liquid crystal display panels and organic electroluminescent display panels. Currently, people have increasingly higher requirements for display effects, but the brightness of existing display panels, especially the front brightness, still needs to be improved. In current technologies, meeting brightness requirements would result in higher power consumption; at the same time, color shift may occur at small and medium viewing angles (e.g., ±30°).

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0019] In one exemplary embodiment of this disclosure, the light-emitting devices in the nth and (n+2)th columns include second and third light-emitting devices alternately distributed along the column direction; the light-emitting devices in the (n+1)th and (n+3)th columns are the first light-emitting devices. The light-emitting devices in the (n+1)th and (n+2)th columns overlap with the first type of light-transmitting portion; In the nth column of light-emitting devices, only one of the second light-emitting device and the third light-emitting device overlaps with the first type of light-transmitting portion.

[0020] In one exemplary embodiment of this disclosure, the light-transmitting portion further includes a plurality of third-type light-transmitting portions, the number of the third-type light-transmitting portions being less than the number of the light-emitting devices, and one of the third-type light-transmitting portions overlapping one of the light-emitting devices; The third type of light-transmitting portion extends toward and adjacent to a light-emitting device that overlaps with it; The first light-emitting device and the third light-emitting device overlap with the first type of light-transmitting portion; The second light-emitting device overlaps with the third type of light-transmitting part.

[0021] In one exemplary embodiment of this disclosure, the light-transmitting portion further includes a plurality of third-type light-transmitting portions, the number of the third-type light-transmitting portions being less than the number of the light-emitting devices, and one of the third-type light-transmitting portions overlapping one of the light-emitting devices; The third type of light-transmitting portion extends toward and adjacent to a light-emitting device that overlaps with it; The first light-emitting device and the second light-emitting device overlap with the first type of light-transmitting portion; The third light-emitting device overlaps with the third type of light-transmitting part.

[0022] In one exemplary embodiment of this disclosure, the extension directions of two adjacent third-type light-transmitting portions are different.

[0023] In one exemplary embodiment of this disclosure, the maximum distance between the boundary of the third type of light-transmitting portion and the boundary of the orthogonal projection of the light-emitting device toward it on the driving back plate is not less than 3 μm.

[0024] In one exemplary embodiment of this disclosure, the first light-emitting device is green, the second light-emitting device is red, and the third light-emitting device emits blue light; the orthographic projection of the third light-emitting device on the driving backplate is greater than the orthographic projection of the second light-emitting device on the driving backplate.

[0027] According to one aspect of this disclosure, a display device is provided, comprising the display panel described in any of the preceding claims.

[0028] The present invention discloses a display panel and display device in which at least part of the light emitted by the light-emitting device can enter the light-transmitting part. Since the refractive index of the light-transmitting part is greater than that of the partition part, some of the light can undergo total internal reflection or refraction at the interface where the side wall of the light-transmitting part and the partition part meet, thereby reducing the divergence angle and achieving light focusing. This can improve the front brightness without increasing power consumption; in other words, power consumption can be reduced while keeping the front brightness unchanged.

[0029] Meanwhile, since the light-emitting devices that overlap with the first type of light-transmitting part and those that do not overlap with the first type of light-transmitting part have different light-focusing effects, the light-focusing effects of at least two different colored light-emitting devices are different. Thus, the proportion of different colors in color mixing can be adjusted by different light-focusing effects to improve color deviation.

[0030] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0069] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0070] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0071] In this document, the row direction X and column direction Y are simply two intersecting directions; for example, the row direction X and column direction Y are perpendicular to each other. Although the row direction X is horizontal and the column direction Y is vertical in the accompanying drawings of this disclosure, it is not limited to this. If the display panel is rotated, the actual orientation of the row direction X and column direction Y may change.

[0072] In this article, "overlapping" of A and B means that the orthographic projections of A and B on the driving backplane or substrate have overlapping areas, while "non-overlapping" of A and B means that the orthographic projections of A and B do not have overlapping areas.

[0073] This disclosure provides a display panel, such as... Figure 1As shown, the display panel includes a display area AA and a peripheral area WA located outside the display area AA. The peripheral area WA can be a continuous annular area surrounding the display area AA, or it can be a discontinuous area surrounding the display area AA. The display area AA can emit light to display images, while the peripheral area WA does not emit light.

[0074] like Figure 3 and Figure 6 As shown, the display panel may include a driving backplate BP and multiple light-emitting devices (LDs) disposed on one side of the driving backplate BP, wherein: The driving backplane BP has a driving circuit that drives the light-emitting device LD to emit light in order to display an image. In some embodiments of this disclosure, the driving backplane BP may include a substrate SU and a circuit layer TL located on one side of the substrate SU, wherein the substrate SU may be a flat plate structure.

[0075] The circuit layer TL includes the aforementioned driving circuitry. For example, the driving circuitry may include pixel circuitry located in the display area AA and peripheral circuitry located in the peripheral area WA. The pixel circuitry can be a 7T1C, 8T1C, or similar structure, as long as it can drive the light-emitting diodes (LDs) to emit light. No special limitations are placed on its structure here. Here, nTmC indicates that one pixel circuit includes n thin-film transistors (represented by the letter "T") and m capacitors (represented by the letter "C"). The number of pixel circuits can be the same as the number of light-emitting diodes (LDs), and they are connected one-to-one with each LD. Of course, multiple LDs can be connected to the same pixel circuit; no special limitations are placed here.

[0076] The peripheral circuit is connected to the pixel circuit and is used to input driving signals to the pixel circuit in order to control the light-emitting device (LD) to emit light. The peripheral circuit may include a gate driving circuit and a light-emitting control circuit, and of course, it may also include other circuits. The specific structure of the peripheral circuit is not specifically limited here.

[0077] The aforementioned circuit layer TL may include multiple thin-film transistors (TFTs) and capacitors. The TFTs may be top-gate or bottom-gate type TFTs, and each TFT may include an overlapping active layer and a gate. The active layers of each TFT are disposed on the same semiconductor layer; alternatively, they may be disposed on multiple semiconductor layers, with the active layers of different TFTs distributed on different semiconductor layers. The material of the semiconductor layer may be polycrystalline silicon or metal oxide, without special limitation.

[0078] Taking a top-gate thin-film transistor as an example, the circuit layer TL may include a semiconductor layer, a first gate insulating layer, a first gate layer, a second gate insulating layer, a second gate layer, an interlayer dielectric layer, a first source / drain layer, a passivation layer, a first planarization layer, a second source / drain layer, and a second planarization layer stacked sequentially along the direction away from the substrate SU. The active layer of the thin-film transistor is located on the semiconductor layer, the gate is located on the gate layer, and the two plates of the capacitor are located on the first gate layer and the second gate layer. The first source / drain layer and the second source / drain layer are used to realize the connection between at least some of the thin-film transistors and between the thin-film transistors and the capacitor, and are used to transmit driving signals. The type of driving signal and the specific pattern of each film layer depend on the specific configuration of the driving circuit and are not specifically limited here.

[0079] The light-emitting device (LD) is located within the display area AA. It can be an OLED (organic light-emitting diode) using organic light-emitting materials, or a Mini LED (sub-millimeter light-emitting diode with a size of 100μm-200μm), Micro LED (micro light-emitting diode with a size of no more than 100μm), or LED (light-emitting diode with a size of more than 200μm) using inorganic light-emitting materials. No special restrictions are imposed here, as long as it can emit light.

[0080] like Figure 3 and Figure 6 As shown, taking an OLED as an example, the light-emitting device (LD) may include a first electrode (ANO), an emissive layer (EL), and a second electrode (CAT) stacked sequentially along the direction away from the driving backplane (BP). By applying an electrical signal to the first electrode (ANO) and the second electrode (CAT), the emissive layer (EL) can be excited to emit light. The light-emitting principle of OLED will not be detailed here. The first electrode (ANO) can serve as the anode, and the second electrode (CAT) can serve as the cathode; both are made of conductive materials such as metals and metal oxides. The emissive layer (EL) may include a hole injection layer, a hole transport layer, an emissive material layer, an electron transport layer, and an electron injection layer stacked sequentially along the direction away from the driving backplane (BP). Of course, other structures can also be used, as long as they can cooperate with the first electrode (ANO) and the second electrode (CAT) to emit light.

[0081] like Figure 3 and Figure 6 As shown, the display panel may further include a pixel definition layer (PDL) separating light-emitting devices (LDs), which may be disposed on the same surface as the driving backplane (BP) as the light-emitting devices (LDs). For example, the pixel definition layer (PDL) may be disposed on the surface of the second planarization layer away from the substrate (SU) along with the first electrode (ANO). Simultaneously, the thickness of the pixel definition layer (PDL) is greater than the thickness of the first electrode (ANO), and it covers a portion of each first electrode (ANO), and has pixel openings (PH) exposing each first electrode (ANO), with one pixel opening (PH) exposing one first electrode (ANO).

[0082] like Figure 3and Figure 6 As shown, each light-emitting device (LD) is defined by a pixel definition layer (PDL). The range of the pixel opening (PH) is the range of the LD; that is, the shape and size of the orthographic projection of the pixel opening (PH) onto the driving backplane (BP) are the same as the shape and size of the orthographic projection of the LD onto the driving backplane (BP). Simultaneously, the shape of the pixel opening (PH) is the shape of its orthographic projection onto the driving backplane (BP) and the substrate (SU), etc. This shape can be a rectangle or other polygon, or a circle, etc. In this paper, the definition of the shape and size of the LD is based on the shape and size of the pixel opening (PH). For example, the size of the LD is the size of its pixel opening (PH).

[0083] like Figures 2-11 As shown, the above-mentioned light-emitting device LD includes at least three light-emitting device LDs with different light-emitting colors. Each light-emitting device LD can be divided into multiple light-emitting units. One light-emitting unit includes at least three light-emitting device LDs with different colors, and the light-emitting colors of the at least three light-emitting device LDs in the same light-emitting unit are different.

[0084] like Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments of this disclosure, each light-emitting device (LD) includes a first light-emitting device LD1, a second light-emitting device LD2, and a third light-emitting device LD3 with different light-emitting colors. For example, the first light-emitting device LD1 is green and is used to emit green light; the second light-emitting device LD2 is red and is used to emit red light; and the third light-emitting device LD3 is blue and is used to emit blue light.

[0085] It should be noted that in the top view of this article, in order to facilitate the representation of the position of the light-transmitting part 11 and the light-emitting device LD, the light-emitting device LD is simplified by using pixel openings that define the range of the light-emitting device LD, and the first electrode ANO, the light-emitting layer EL and the second electrode CAT are not shown.

[0086] There are multiple light-emitting devices (LDs) of each color, but the number of LDs of different colors may not be the same. For example, the same light-emitting unit includes a first light-emitting device LD1, a second light-emitting device LD2, and a third light-emitting device LD3.

[0087] like Figure 2As shown, in some embodiments of this disclosure, since the lifespan of the light-emitting layer EL of light-emitting devices LDs of different emitting colors varies, the degree of luminous efficiency decay differs as the luminous duration increases. Therefore, the size of the light-emitting devices LDs can be different, and a larger size can be used to compensate for the lack of luminous efficiency. For example, under the same luminous duration, in terms of the degree of luminous efficiency decay, materials emitting blue and red light are smaller than materials emitting green light, and further, materials emitting red light are smaller than materials emitting green light. Therefore, the size of the second light-emitting device LD2 and the third light-emitting device LD3 can be larger than the size of the first light-emitting device LD1; the size of the third light-emitting device LD3 is larger than the size of the second light-emitting device LD2, thereby improving the uniformity of the brightness of the three.

[0088] like Figure 2 As shown, in some embodiments of this disclosure, the outline of the orthographic projection of the light-emitting device (LD) on the driving backplane (BP) is formed by multiple sides and arc edges, with adjacent sides connected by an arc edge. For example, the outline of the orthographic projection of each light-emitting device (LD) on the driving backplane (BP) has four sides and four arc edges, and the four sides are distributed along a rectangular trajectory. The lengths of two opposite sides in the first light-emitting device (LD1) are greater than the lengths of the other two opposite sides. The lengths of the four sides of the second light-emitting device (LD2) can be equal. The length of one arc edge in the third light-emitting device (LD3) is greater than the lengths of the other arc edges. One diagonal of the rectangular trajectory where the four sides of the second light-emitting device (LD2) and the third light-emitting device (LD3) are located extends along the column direction Y, and the other diagonal can extend along the row direction X. The diagonal of the rectangular trajectory where the four sides of the first light-emitting device (LD1) are located intersects the row direction X and the column direction Y.

[0089] like Figure 2 As shown, in some embodiments of this disclosure, the light-emitting devices LDs can be arranged in multiple rows and columns. The light-emitting devices in the i-th column include second light-emitting devices LD2 and third light-emitting devices LD3, which are alternately distributed along the column direction Y. The light-emitting devices in the (i+1)-th column are first light-emitting devices LD1, meaning that the second light-emitting devices LD2 and third light-emitting devices LD3 are not in the same column as the first light-emitting device LD1. Similarly, the light-emitting devices in the j-th row include second light-emitting devices LD2 and third light-emitting devices LD3, which are alternately distributed along the row direction X. The light-emitting devices in the (j+1)-th row are first light-emitting devices LD1, meaning that the second light-emitting devices LD2 and third light-emitting devices LD3 are not in the same row as the first light-emitting device LD1. Both i and j are positive integers not less than 2. Furthermore, each second light-emitting device LD2 can be surrounded by at least two first light-emitting devices LD1, and each third light-emitting device LD3 can be surrounded by at least two first light-emitting devices LD1. The portion of the first light-emitting devices LD1 surrounding an adjacent second light-emitting device LD2 can be reused to surround an adjacent third light-emitting device LD3.

[0090] like Figure 6 As shown, to prevent corrosion from external moisture, the display panel may also include a TFE encapsulation layer, which can cover each light-emitting device (LD). For example, the TFE encapsulation layer can be a thin-film encapsulation method, which may include a first inorganic layer, an organic layer, and a second inorganic layer, wherein: The first inorganic layer can cover each light-emitting device (LD). The organic layer can be disposed on the surface of the first inorganic layer away from the driving backplane (BP), and the boundary of the organic layer can be defined inside the boundary of the first inorganic layer by a barrier dam located in the peripheral area (WA). The second inorganic layer can cover the organic layer and the first inorganic layer not covered by the organic layer, and can block the intrusion of water and oxygen.

[0091] like Figure 6 As shown, the display panel also includes a dimming layer 1, which can be disposed on the side of the light-emitting device (LD) away from the driving backplane (BP). For example, the dimming layer 1 can be disposed on the side of the encapsulation layer (TFE) away from the driving backplane (BP). Simultaneously, the dimming layer 1 includes multiple light-transmitting portions 11 and separating portions 12 that separate the light-transmitting portions 11. Both the light-transmitting portions 11 and the separating portions 12 are light-transmitting structures; for example, both the light-transmitting portions 11 and the separating portions 12 are made of light-transmitting organic materials such as optical adhesives. The refractive index of the light-transmitting portions 11 is greater than that of the separating portions 12 (for light of the same wavelength). Alternatively, the separating portions 12 can be considered as a mesh structure with multiple light-transmitting holes, with one light-transmitting portion 11 filling each light-transmitting hole.

[0092] like Figure 6 As shown, the light-transmitting part 11 can overlap with the light-emitting device LD, so that at least part of the light emitted by the light-emitting device LD can enter the light-transmitting part 11, and refraction and total internal reflection occur at the interface where the light-transmitting part 11 and the separating part contact. Through refraction and total internal reflection, at least part of the light can be focused, thereby improving the brightness at small and medium viewing angles, that is, the brightness of the front of the display panel, without increasing power consumption; that is, reducing power consumption without reducing the brightness of the front.

[0093] The inventors discovered that because the sizes of light-emitting diodes (LDs) of different colors vary, the contribution rates of different colors of light in the mixed white light are different. For example, R (red light):G (green light):B (blue light) = 0.25:0.2:0.5; and in L-Decay@30° (brightness decay at a 30° viewing angle), the contribution ratio of each color is R:G:B = 0.25:0.71:0.07. It can be seen that the effects of different colored LDs are not the same. Specifically, the green light-emitting LD has a greater impact on L-Decay; this can easily cause color shift problems such as a pinkish or bluish tint. To address this, the inventors propose that by designing the dimming layer 1, different degrees of light focusing can be applied to light-emitting devices (LDs) of different colors, thereby reducing color shift while achieving the aforementioned functions of increasing brightness and reducing power consumption. For example, some LDs can have a light-transmitting portion 11, while others can be without it; or, all LDs can have a light-transmitting portion 11, but with different degrees of light focusing in each portion. Of course, the two solutions mentioned above can also be combined. A detailed explanation follows: The present disclosure discloses two concepts for achieving light focusing in the light-transmitting portion 11; among which: like Figure 6 As shown, based on the first concept, the sidewall of the light-transmitting part 11 (the outer peripheral surface of the light-transmitting part 11) expands in a direction away from the driving back plate BP, so that the outline of the light-transmitting part 11 along the cross section perpendicular to the driving back plate BP can be an inverted trapezoid (the end closer to the driving back plate BP is the small end); part of the light emitted by the light-emitting device LD can undergo total internal reflection at the interface where the light-transmitting part 11 and the partition part 12 contact, thereby achieving light focusing.

[0094] like Figure 6 and Figure 7 As shown, under the first concept, a first light-transmitting layer 101 can be formed first, and then patterned using processes such as photolithography to obtain multiple light-transmitting holes 121. The area outside the light-transmitting holes 121 is a partition. The sidewalls of the light-transmitting holes 121 can expand in a direction away from the driving backplate BP. Then, a second light-transmitting layer 102 is used to cover the first light-transmitting layer 101 and fill the light-transmitting holes 121. The portion of the second light-transmitting layer 102 filled within the light-transmitting holes 121 is the light-transmitting portion 11. The refractive index of the first light-transmitting layer 101 is less than that of the second light-transmitting layer 102.

[0095] like Figure 16As shown, based on the second concept, in some embodiments, the sidewall of the light-transmitting part 11 (the outer peripheral surface of the light-transmitting part 11) can shrink in a direction away from the driving back plate BP, so that the outline of the light-transmitting part 11 along the cross section perpendicular to the driving back plate BP can be a trapezoid (the end closer to the driving back plate BP is the large end); part of the light emitted by the light-emitting device LD can be refracted at the interface where the light-transmitting part 11 and the partition part 12 are in contact. When entering the low-refractive-index medium (partition part 12) from the high-refractive-index medium (light-transmitting part 11), the angle of refraction is greater than the angle of incidence, thus achieving light focusing.

[0096] like Figure 16 and Figure 17 As shown, under the second concept, in some embodiments, a first light-transmitting layer 101 can be formed first, and then patterned using processes such as photolithography to obtain multiple light-transmitting portions 11; the sidewalls of the light-transmitting portions 11 can shrink in a direction away from the driving backplate BP; then, a second light-transmitting layer 102 is used to cover the first light-transmitting layer 101, filling the area outside the light-transmitting portions 11 to obtain the partition portion 12. The refractive index of the first light-transmitting layer 101 is greater than that of the second light-transmitting layer 102.

[0097] Of course, the side wall of the light-transmitting part 11 (the outer peripheral surface of the light-transmitting part 11) can also be perpendicular to the driving back plate BP. Some of the light emitted by the light-emitting device LD can undergo total internal reflection and refraction at the interface where the light-transmitting part 11 and the partition part 12 meet, thereby achieving light concentration.

[0098] like Figures 3-6 , Figures 13-16 As shown, due to the limited distance between the dimming layer 1 and the light-emitting device LD, in order to ensure that some of the light emitted by the light-emitting device LD can reach the interface where the light-transmitting part 11 and the separating part 12 meet, and to prevent light with a wide viewing angle from escaping from the separating part 12 without passing through this interface, the range of the light-emitting device LD can be made no larger than the range of the light-transmitting part 11 that overlaps with it. That is, the orthographic projection of the light-emitting device LD on the driving backplate BP is located within the orthographic projection of the light-transmitting part 11 that overlaps with it on the driving backplate BP. However, if the range of the light-transmitting part 11 is too large, the light may also bypass the aforementioned interface and be emitted directly from the light-transmitting part 11. In other words, if the light-transmitting part 11 is too small or too large, it may affect the light-gathering effect. Therefore, to achieve light gathering, the distance D between the boundary of the orthographic projection of the light-emitting device LD on the driving backplate BP and the boundary of the orthographic projection of the light-transmitting part 11 that overlaps with it on the driving backplate BP can be within a specified range. This specified range can be no less than 1 μm and no more than 2.5 μm, for example, 2 μm.

[0099] like Figure 3 , Figure 4 , Figure 23 , Figure 24 , Figure 33 and Figure 34As shown, based on the above relationship between the light-transmitting portion 11 and the light-emitting device LD, the light-transmitting portion 11 can be divided into three categories: the first type of light-transmitting portion 111, the second type of light-transmitting portion 112, and the third type of light-transmitting portion 113, wherein: like Figure 3 and Figure 6 As shown, the first type of light-transmitting part 111 overlaps with only one light-emitting device LD, and the orthographic projection of the light-emitting device LD on the driving back plate BP is located within the orthographic projection of the light-transmitting part 11 overlapping with it on the driving back plate BP. The outer peripheral surface of the first type of light-transmitting part 111 can refract or totally reflect the light emitted by the light-emitting device LD.

[0100] like Figure 23 and Figure 26 As shown, the second type of light-transmitting portion 112 overlaps with multiple light-emitting devices (LDs) simultaneously, and the orthographic projections of the multiple light-emitting devices (LDs) on the driving backplate BP are located within the orthographic projections of the overlapping light-transmitting portion 11 on the driving backplate BP; simultaneously, the distance between a portion of the boundary of the orthographic projection of the light-emitting device (LD) on the driving backplate BP and a portion of the boundary of the orthographic projection of the light-transmitting portion 11 on the driving backplate BP is within the aforementioned specified range, which can achieve the aforementioned light-focusing effect, while the distance in other areas is greater than the specified range, which weakens or eliminates the light-focusing effect; for example, the orthographic projections of the light-emitting device (LD) and the overlapping light-transmitting portion 11 on the driving backplate BP are both surrounded by multiple sides, and only Some sides are parallel and the spacing is within a specified range, while the spacing of other sides is not parallel and is greater than the specified range. Therefore, only the area corresponding to the side with the spacing within the specified range can achieve a light-focusing effect, while the light-focusing effect of the area corresponding to other sides is weak or non-existent. In addition, among the light-emitting devices LDs overlapping with the second type of light-transmitting part 112, there may be some light-emitting devices LDs whose side of the orthographic projection on the driving back plate BP is more than the specified range from any side of the light-transmitting part 11, so that the light-transmitting part 11 does not achieve a light-focusing effect on the light-emitting device LD. Thus, a light-transmitting part 11 can achieve different light-focusing effects on different light-emitting devices LDs.

[0101] like Figures 33-36As shown, the third type of light-transmitting portion 113 overlaps only with a light-emitting device LD, but the third type of light-transmitting portion 113 extends towards a light-emitting device LD adjacent to the overlapping light-emitting device LD, so that a part of the third type of light-transmitting portion 113 does not overlap with the light-emitting device LD. Moreover, through the aforementioned extension, the distance between the boundary of the third type of light-transmitting portion 113 and the boundary of the light-emitting device LD can be increased locally, making the distance greater than the specified range mentioned above. For example, the orthographic projection of the light-emitting device LD on the driving backplate BP is located within the orthographic projection of the third type of light-transmitting portion 113 on the driving backplate BP, and the distance between the boundary of the third type of light-transmitting portion 113 and the boundary of the light-emitting device LD is greater than the specified range mentioned above, for example, greater than 2.5 μm. That is, the maximum distance between the boundaries of the orthographic projections of the third type of light-transmitting portion 113 and the overlapping light-emitting device LD on the driving backplate BP is greater than 2.5 μm. Thus, the light-gathering effect is weakened or not generated in the non-overlapping area, thereby achieving local light gathering through the third type of light-transmitting portion 113. At the same time, the distance L between the boundary of the third type of light-transmitting part 113 and the boundary of the light-emitting device LD it faces is not less than 3μm, thereby increasing the light-transmitting part 11 while avoiding overlap with the light-emitting device LD it faces due to process errors.

[0102] In some embodiments of this disclosure, the orthographic projection of the light-emitting device LD on the driving backplate BP is located within the orthographic projection of a third type of light-transmitting portion 113 on the driving backplate BP, and the two have the same shape; the boundary of the orthographic projection of the third type of light-transmitting portion 113 on the driving backplate BP includes multiple sides, and the outline of the orthographic projection of the light-emitting device LD on the driving backplate BP includes multiple sides. The sides of the third type of light-transmitting portion 113 and the sides of the light-emitting device LD are arranged parallel to each other in a one-to-one correspondence. The spacing between a set of parallel sides is not less than 3 μm, while the spacing D of other parallel sides is not greater than 2.5 μm.

[0103] like Figures 3-22 As shown, in the first embodiment of this disclosure, the number of light-transmitting portions 11 is less than the number of light-emitting devices LD, and all light-transmitting portions 11 are first-type light-transmitting portions 111, so that only a portion of the light-emitting devices LD overlap with the light-transmitting portions 11 (first-type light-transmitting portions 111), while the other portion of the light-emitting devices LD do not have light-transmitting portions 11 overlapping with them; correspondingly, the light emitted by the light-emitting devices LD overlapping with the first-type light-transmitting portions 111 at a certain angle is totally reflected, and light can be focused in the circumferential direction, while the light emitted by the light-emitting devices LD that do not overlap with the light-transmitting portions 11 will not be focused by the first-type light-transmitting portions 111; at the same time, the colors of at least one light-emitting device LD overlapping with the first-type light-transmitting portions 111 and at least one light-emitting device LD that does not overlap with the first-type light-transmitting portions 111 can be different, so that within a certain viewing angle, the brightness of some colors of light is enhanced, while other colors are not enhanced, and the color mixing ratio can be adjusted in this way to improve color deviation.

[0104] like Figures 3-6 As shown, in the first embodiment of the first type, the aforementioned first concept is adopted, and the sidewall of the light-transmitting portion 11 expands in a direction away from the driving backplate BP. The nth column light-emitting device LD includes second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the column direction Y; the (n+1)th column light-emitting devices are all first light-emitting devices LD1. At the same time, the nth row light-emitting device LD includes second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the row direction X; the (n+1)th row light-emitting device LD is all first light-emitting device LD1.

[0105] The light-emitting devices LD in the nth column all overlap with the first type of light-transmitting part 111, while the light-emitting devices LD in the (n+1)th column do not overlap with the light-transmitting part 11. That is to say, the number of light-transmitting parts 11 can be equal to the sum of the number of second light-emitting devices LD2 and third light-emitting devices LD3, and all of them are first type of light-transmitting parts 111. Each first type of light-transmitting part 111 overlaps with each second light-emitting device LD2 and third light-emitting device LD3 in a one-to-one correspondence, playing a light-concentrating role, while the first light-emitting device LD1 has no light-transmitting part 11 to concentrate light.

[0106] The first light-emitting device LD1 emits green light, the second light-emitting device LD2 emits red light, and the third light-emitting device LD3 emits blue light. Since the luminous efficiency of the first light-emitting device LD1 is higher than that of the second and third light-emitting devices LD2 and LD3, focusing light on the second and third light-emitting devices LD2 and LD3 is beneficial to reducing the power consumption of the second and third light-emitting devices LD2 and LD3, thereby reducing the power consumption after color mixing. It can also balance the color shift caused by the higher proportion of the first light-emitting device LD1 in the brightness.

[0107] like Figures 8-12 As shown, in the second embodiment of the first type, the aforementioned second concept is adopted, and the sidewall of the light-transmitting portion 11 contracts in a direction away from the driving back plate BP. The nth column of light-emitting devices LD includes second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the column direction Y; the (n+1)th column of light-emitting devices LD is a first light-emitting device LD1. The nth column of light-emitting devices LD overlaps with the first type of light-transmitting portion 11. Each second light-emitting device LD2 and third light-emitting device LD3 may be provided with a first type of light-transmitting portion 111, while each first light-emitting device LD1 is not provided with a light-transmitting portion 11. The number and arrangement of the light-transmitting portions 11 can be the same as in the first embodiment described above, and will not be detailed here.

[0108] like Figures 13-17As shown, in the third embodiment of the first type, the second concept described above is adopted, and the sidewall of the light-transmitting portion 11 contracts in a direction away from the driving back plate BP. The nth column light-emitting device LD includes second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the column direction Y; the (n+2)th column light-emitting devices include second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the column direction Y; the (n+1)th column light-emitting devices are all first light-emitting devices LD1. At the same time, the nth row light-emitting device LD includes second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the row direction X; the (n+1)th row light-emitting device LD is all first light-emitting device LD1.

[0109] The light-emitting devices (LDs) in columns n and n+1 overlap with the first type of light-transmitting portion 111. That is, all first light-emitting devices LD1 and the second and third light-emitting devices LD2 and LD3 in column n overlap with the first type of light-transmitting portion 111. However, in column n+2, only the second light-emitting device LD2 overlaps with the first type of light-transmitting portion 111, while the third light-emitting device LD3 does not overlap. The first type of light-transmitting portion 111 can focus the light on the first light-emitting devices LD1, LD2, and some of the third light-emitting devices LD3, while some of the third light-emitting devices LD3 do not have this light-concentrating effect. The first light-emitting device LD1 emits green light, the second light-emitting device LD2 emits red light, and the third light-emitting device LD3 emits blue light. This reduces power consumption while balancing the bluish tint caused by the higher proportion of brightness in the third light-emitting device LD3.

[0110] like Figures 18-22 As shown, in the fourth embodiment of the first type, the second concept described above is adopted, and the sidewall of the light-transmitting portion 11 contracts in a direction away from the driving back plate BP. The nth column light-emitting device LD includes second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the column direction Y; the (n+2)th column light-emitting device includes second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the column direction Y; the (n+1)th and (n+3)th columns light-emitting devices are all first light-emitting devices LD1. At the same time, the nth row light-emitting device LD includes second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the row direction X; the (n+1)th row light-emitting device LD is all first light-emitting device LD1.

[0111] The light-emitting devices (LDs) in columns n+1 and n+2 overlap with the first type of light-transmitting portion 111. That is, the first light-emitting device LD1 in column n+1 and the second and third light-emitting devices LD2 and LD3 in column n+2 all overlap with the first type of light-transmitting portion 111. However, in column n, only the third light-emitting device LD3 overlaps with the first type of light-transmitting portion 111, while the second light-emitting device LD2 does not overlap with the light-transmitting portion 111. The first light-emitting device LD1 in column n+3 also does not overlap with the light-transmitting portion 111. If the column containing the first light-emitting device LD1 is defined as the first column, and the column containing the second and third light-emitting devices LD2 and LD3 is defined as the second column, then the first column with the first type of light-transmitting portion 111 and the first column without the light-transmitting portion 111 are alternately distributed along the row direction X. The second column with the first type of light-transmitting portion 111 partially and the second column with the first type of light-transmitting portion 111 completely are also alternately distributed along the row direction X.

[0112] The first type of light-transmitting part 111 can focus light on a portion of the first light-emitting device LD1, a portion of the second light-emitting device LD2, and all of the third light-emitting device LD3, while the portion of the first light-emitting device LD1 and the portion of the third light-emitting device LD3 do not have the light-transmitting part 11 to focus light. The first light-emitting device LD1 emits green light, the second light-emitting device LD2 emits red light, and the third light-emitting device LD3 emits blue light; this can reduce power consumption and balance the problem of pinkish color caused by the higher proportion of brightness in the second light-emitting device LD2.

[0113] like Figures 23-32 As shown, in the second embodiment of this disclosure, the light-transmitting portion 11 includes a first type of light-transmitting portion 111 and a second type of light-transmitting portion 112. A portion of the light emitted by the light-emitting device LD overlapping with the first type of light-transmitting portion 111 is totally internally reflected, achieving circumferential focusing. However, among the light-emitting devices LD overlapping with the second type of light-transmitting portion 112, only a portion of the light emitted by some of the light-emitting devices LD is focused by the second type of light-transmitting portion 112. Simultaneously, at least two light-emitting devices LD overlapping the same second type of light-transmitting portion 112 can be made to have different colors, so that within a certain viewing angle, the brightness of some colors of light is enhanced, while other colors are not enhanced. This method can adjust the color mixing ratio, thereby improving color shift.

[0114] like Figures 23-27As shown, in the second type of first embodiment, the aforementioned first concept is adopted, and the sidewall of the light-transmitting portion 11 expands in a direction away from the driving backplate BP. The first light-emitting device LD1 overlaps with the second type of light-transmitting portion 112; a portion of the second light-emitting device LD2 and a portion of the third light-emitting device LD3 overlap with the first type of light-transmitting portion 111, and a portion of the second light-emitting device LD2 and a portion of the third light-emitting device LD3 overlap with the second type of light-transmitting portion 112. The light-focusing effect of the second light-emitting device LD2 and the third light-emitting device LD3 overlapping with the first type of light-transmitting portion 111 is stronger than that of the light-emitting device LD overlapping with the second type of light-transmitting portion 112. Under the premise of reducing power consumption, color shift can be improved by different light-focusing effects.

[0115] Furthermore, the light-emitting devices LD in the nth column include second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the column direction Y; the light-emitting devices LD in the (n+2)th column include second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the column direction Y; the light-emitting devices in the (n+1)th and (n+3)th columns are all first light-emitting devices LD1. Meanwhile, the light-emitting devices LD in the nth row include second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the row direction X; the light-emitting devices LD in the (n+1)th row are all first light-emitting devices LD1.

[0116] like Figure 23 and Figure 24 As shown, the second type of light-transmitting portion 112 is a strip-shaped structure extending along the column direction Y; the nth column light-emitting device LD overlaps with the first type of light-transmitting portion 111; the (n+1), (n+2), and (n+3)th column light-emitting devices LD overlap with the same second type of light-transmitting portion 112. The first type of light-transmitting portion 111 can focus light on the second light-emitting device LD2 and the third light-emitting device LD3 in the nth column, while the (n+2)th column light-emitting device LD is located between the (n+1)th and (n+3)th column light-emitting devices LD. The boundary of the second type of light-transmitting portion 112 distributed along the row direction X is close to the first light-emitting device LD1 in the (n+1)th and (n+3)th columns, which can focus light locally, but does not focus light on the second light-emitting device LD2 and the third light-emitting device LD3 in the (n+2)th column. This results in some colors of light being enhanced in brightness within a certain viewing angle, while other colors are not enhanced. Furthermore, the enhancement effect on the light-emitting device LD in the nth column is greater than the enhancement effect on the light-emitting devices LD in the (n+1)th and (n+3)th columns, thereby adjusting the color mixing ratio and improving color deviation.

[0117] For example, the first light-emitting device LD1 emits green light, the second light-emitting device LD2 emits red light, and the third light-emitting device LD3 emits blue light. It has been verified that in a unit formed by 4×4 light-emitting devices LD, 50% of the third light-emitting devices LD3 have a focusing effect within a viewing angle of 45° and -45°, and another 50% of the third light-emitting devices LD3 have a focusing effect within a viewing angle of 135° and -135°. Compared with the scheme of setting a first type of light-transmitting part 111 for each light-emitting device LD, it can not only reduce power consumption, but also have a 50% benefit in L-decay, thus balancing power consumption and L-decay.

[0118] Furthermore, the light-emitting devices (LDs) in the (n+1)th column and the (n+2)th column alternate in the column direction Y, meaning that any LD in the (n+1)th column is not in the same row as any LD in the (n+2)th column. Similarly, the light-emitting devices in the (n+3)th column and the (n+2)th column alternate in the column direction Y, meaning that any LD in the (n+3)th column is not in the same row as any LD in the (n+2)th column. Of course, any LD in the (n+1)th column and any LD in the (n+3)th column are in the same row.

[0119] like Figure 23 and Figure 24 As shown, the orthographic projection of the light-emitting device LD on the driving backplate BP is located within the orthographic projection of the light-transmitting portion 11 overlapping with it on the driving backplate BP; the second type of light-transmitting portion 112 is recessed inward in the region corresponding to the second light-emitting device LD2 and the third light-emitting device LD3 overlapping with it, forming a serrated profile with multiple edges connected sequentially along the column direction Y. For example, the orthographic projection of the light-emitting device LD on the driving backplate BP includes multiple circumferentially distributed side edges. The two side edges of the first light-emitting device LD1 are arranged parallel to the two edges of the aforementioned second type of light-transmitting portion 112, and the spacing is within the specified range mentioned above. Therefore, light can be focused at the position corresponding to the side edge, while other side edges do not focus light. That is, the second type of light-transmitting portion 112 can locally focus light on the first light-emitting device LD1.

[0120] like Figures 28-32As shown, in the second embodiment of the second type, the first concept described above is adopted, and the sidewall of the light-transmitting portion 11 expands in a direction away from the driving backplate BP. A portion of the first light-emitting device LD1 overlaps with the first type of light-transmitting portion 111, and a portion of the first light-emitting device LD1 overlaps with the second type of light-transmitting portion 112; the second light-emitting device LD2 and a portion of the third light-emitting device LD3 both overlap with the second type of light-transmitting portion 112. The light-focusing effect of the second light-emitting device LD2 and the third light-emitting device LD3 overlapping with the first type of light-transmitting portion 111 is stronger than that of the light-emitting device LD overlapping with the second type of light-transmitting portion 112. While reducing power consumption, color shift can be improved through different light-focusing effects.

[0121] Furthermore, the light-emitting devices in the nth and (n+2)th columns are all first light-emitting devices LD1. The light-emitting devices LD in the (n+1)th column include second light-emitting devices LD2 and third light-emitting devices LD3, which are alternately distributed along the column direction Y. The light-emitting devices LD in the (n+3)th column also include second light-emitting devices LD2 and third light-emitting devices LD3, which are alternately distributed along the column direction Y. Meanwhile, the light-emitting devices LD in the nth row include second light-emitting devices LD2 and third light-emitting devices LD3, which are alternately distributed along the row direction X. All the light-emitting devices LD in the (n+1)th row are first light-emitting devices LD1.

[0122] like Figure 28 and Figure 29 As shown, the second type of light-transmitting portion 112 is a strip-shaped structure extending along the column direction Y; the light-emitting device LD in the nth column overlaps with the first type of light-transmitting portion 111; the light-emitting devices LD in the (n+1), (n+2), and (n+3)th columns overlap with the same second type of light-transmitting portion 112. The first type of light-transmitting portion 111 can focus the light on the first light-emitting device LD1 in the nth column, while the light-emitting device LD in the (n+2)th column is located between the light-emitting devices LD in the (n+1)th and (n+3)th columns. The boundary of the second type of light-transmitting portion 112 distributed along the row direction X is close to the second light-emitting device LD2 and the third light-emitting device LD3 in the (n+1)th and (n+3)th columns, which can focus the light locally, but does not focus the light on the first light-emitting device LD1 in the (n+2)th column. This design enhances the brightness of certain localized areas of the first light-emitting device (LD1), the second light-emitting device (LD2), and the third light-emitting device (LD3) within a specific viewing angle, while other areas of these devices remain unenhanced. This allows for adjustment of the color mixing ratio and improvement of color shift. For example, if the first light-emitting device (LD1) emits green light, the second light-emitting device (LD2) emits red light, and the third light-emitting device (LD3) emits blue light, localized focusing on the red and blue light, while defocusing some of the first light-emitting devices (LD1), can improve the pink and bluish color shift issues at specific viewing angles. Simultaneously, the ability to focus some of the first light-emitting devices (LD1) helps reduce power consumption.

[0123] Furthermore, the light-emitting devices (LDs) in the (n+1)th column and the (n+2)th column alternate in the column direction Y, meaning that any LD in the (n+1)th column is not in the same row as any LD in the (n+2)th column. Similarly, the light-emitting devices in the (n+3)th column and the (n+2)th column alternate in the column direction Y, meaning that any LD in the (n+3)th column is not in the same row as any LD in the (n+2)th column. Of course, any LD in the (n+1)th column and any LD in the (n+3)th column are in the same row.

[0124] like Figure 28 and Figure 29 As shown, the orthographic projection of the light-emitting device LD on the driving back plate BP is located within the orthographic projection of the light-transmitting portion 11 overlapping with it on the driving back plate BP; the second type of light-transmitting portion 112 is recessed inward in the area corresponding to the first light-emitting device LD1 overlapping with it, forming a serrated profile with multiple edges connected sequentially along the column direction Y; for example, the orthographic projection of the light-emitting device LD on the driving back plate BP includes multiple circumferentially distributed side edges, and the second light-emitting device LD2 and the third light-emitting device LD3 each have two side edges that are parallel to the two edges of the aforementioned second type of light-transmitting portion 112, and the spacing is within the specified range mentioned above, so light can be focused at the position corresponding to the side edge, while other side edges do not focus light, that is, the second type of light-transmitting portion 112 can locally focus light on the second light-emitting device LD2 and the third light-emitting device LD3.

[0125] like Figures 33-37 As shown, in the third embodiment, the number of third-type light-transmitting portions 113 is less than the number of light-emitting devices (LDs), and one third-type light-transmitting portion 113 overlaps with only one light-emitting device (LD), while other light-emitting devices (LDs) overlap with the first-type light-transmitting portions 111; the color of at least one light-emitting device (LD) overlapping with the first-type light-transmitting portion 111 is different from the color of at least one light-emitting device (LD) overlapping with the third-type light-transmitting portion 113; thus, within a certain viewing angle, the brightness of some colors of light is enhanced, while other colors are not enhanced. The color mixing ratio can be adjusted in this way to improve color deviation.

[0126] like Figures 33-37As shown, in the first embodiment of the third type, the dimming layer 1 can adopt the scheme of the second concept described above, and the sidewall of the light-transmitting part 11 shrinks away from the driving back plate BP. The nth column light-emitting device LD includes second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the column direction Y; the (n+2)th column light-emitting devices include second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the column direction Y. At the same time, the nth row light-emitting device LD includes second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the row direction X; the (n+1)th row light-emitting device LD consists entirely of first light-emitting devices LD1.

[0127] The first light-emitting device LD1 and the second light-emitting device LD2 overlap with the first type of light-transmitting part 111; the third light-emitting device LD3 overlaps with the third type of light-transmitting part 113.

[0128] The light-gathering effect of the first light-emitting device LD1 and the second light-emitting device LD2, which overlap with the first type of light-transmitting part 111, is stronger than that of the third light-emitting device LD3, which overlaps with the third type of light-transmitting part 113. If the first light-emitting device LD1 emits green light, the second light-emitting device LD2 emits red light, and the third light-emitting device LD3 emits blue light, the color shift problem of bluish tint at a certain viewing angle can be improved by different light-gathering effects while reducing power consumption.

[0129] In the second embodiment of the third type, the dimming layer 1 can adopt the scheme described in the second concept above, where the sidewall of the light-transmitting portion 11 tapers away from the driving backplate BP. The nth column light-emitting device LD includes second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the column direction Y; the (n+2)th column light-emitting devices include second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the column direction Y. Meanwhile, the nth row light-emitting device LD includes second light-emitting devices LD2 and third light-emitting devices LD3 alternately distributed along the row direction X; the (n+1)th row light-emitting device LD consists entirely of first light-emitting devices LD1.

[0130] The first light-emitting device LD1 and the third light-emitting device LD3 overlap with the first type of light-transmitting part 111; the second light-emitting device LD2 overlaps with the third type of light-transmitting part 113.

[0131] The light-gathering effect of the first light-emitting device LD1 and the third light-emitting device LD3, which overlap with the first type of light-transmitting part 111, is stronger than that of the second light-emitting device LD2, which overlaps with the third type of light-transmitting part 113. If the first light-emitting device LD1 emits green light, the second light-emitting device LD2 emits red light, and the third light-emitting device LD3 emits blue light, then the color shift problem of pink emission at a certain viewing angle can be improved by different light-gathering effects while reducing power consumption.

[0132] Furthermore, in some embodiments of this disclosure, the extension directions of two adjacent third-type light-transmitting portions 113 in the row direction X and column direction Y are different, which can prevent the formation of patterns that affect the uniformity of the image due to the consistent direction of local light focusing.

[0133] This disclosure also provides a display device, which may include the display panel of any of the above embodiments. The display panel is the same as the display panel described in any of the above embodiments, and its specific structure and beneficial effects can be referred to the embodiments of the display panel described above, and will not be repeated here.
