Fabricating the color film layer (19) requires only two masking processes for the first color filter layer (191) and the second color filter layer (192). Compared with four masking processes, the number of masking processes required for fabricating the color film layer (19) is reduced, which can reduce the manufacturing cost of the display panel. Further provided is a display apparatus comprising the above display panel.

Detailed Implementation

[0061] 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.

[0062] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0063] 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.

[0064] To reduce ambient light reflection and improve contrast, a color filter layer 19 is placed on the side of the light-emitting layer 16 away from the driving backplate 10 instead of a polarizer, making the panel thinner and increasing light transmittance, thereby reducing power consumption. As shown in Figure 1, a light-shielding layer 195 is usually formed when making the color filter layer 19. A light-emitting opening 1951 is set on the light-shielding layer 195, and three different color filter units 197 are set in the light-emitting opening 1951. The light-shielding opening requires a mask process, and each of the three color filter units 197 requires a mask process. Making the color filter layer 19 requires a total of four mask processes, which is costly.

[0065] As shown in Figure 2, in order to save on the masking process, a neutral filter layer 196 is formed on the side of the light-shielding layer 195 away from the driving backplate 10. The neutral filter layer 196 covers the side of the light-shielding layer 195 away from the driving backplate 10 and fills the light-emitting opening 1951 provided on the light-shielding layer 195. The neutral filter layer 196 can transmit three different colors of light: red, green and blue.

[0066] Based on this, the present disclosure provides a display panel. As shown in Figures 3 to 26, the display panel includes a driving backplate 10, a light-emitting layer 16, and a color filter layer 19. The light-emitting layer 16 is disposed on one side of the driving backplate 10 and includes at least three different colored light-emitting devices 160. The color filter layer 19 includes a first filter layer 191 and a second filter layer 192. The orthographic projection of the first filter layer 191 on the driving backplate 10 at least partially overlaps with the orthographic projection of one colored light-emitting device 160 on the driving backplate 10. The orthographic projection of the second filter layer 192 on the driving backplate 10 at least partially overlaps with the orthographic projection of the other colored light-emitting devices 160 on the driving backplate 10. The overlapping area 10 of the first filter layer 191 and the second filter layer 192 in a direction perpendicular to the driving backplate 10 forms a light-shielding area 1901. The first filter layer 191 transmits the emitted light of one colored light-emitting device 160, and the second filter layer 192 transmits the emitted light of the other colored light-emitting devices 160.

[0067] The color filter layer 19 includes a first filter layer 191 and a second filter layer 192. The first filter layer 191 transmits light emitted from the light-emitting device 160 of one color, while the second filter layer 192 transmits light emitted from the light-emitting device 160 of other colors. The first filter layer 191 and the second filter layer 192 overlap in a direction perpendicular to the driving backplate 10 to form a light-shielding area 1901. Manufacturing the color filter layer 19 requires only two masking processes: the first filter layer 191 and the second filter layer 192. Compared to four masking processes, this reduces the masking steps required for manufacturing the color filter layer 19, thus lowering the manufacturing cost of the display panel.

[0068] The display panel involved in this invention will be described in detail below with reference to specific embodiments.

[0069] As shown in Figure 3, a display panel may generally include a substrate 11 and a driving circuit layer 13. The driving circuit layer 13 is disposed on one side of the substrate 11. The display panel may also include a buffer layer 12, which is disposed between the substrate 11 and the driving circuit layer 13.

[0070] The substrate 11 can be an inorganic material or an organic material. For example, in one embodiment of the present invention, the substrate 11 can be made of glass materials such as soda-lime glass, quartz glass, or sapphire glass, or it can be made of metal materials such as stainless steel, aluminum, or nickel.

[0071] In another embodiment of the present invention, the substrate 11 may also be a flexible substrate 11, for example, the material of the substrate 11 may be polyimide (PI). The substrate 11 may also be a composite of multiple materials. For example, in one embodiment of the present invention, the substrate 11 may include a bottom film, a pressure-sensitive adhesive layer, a first polyimide layer and a second polyimide layer stacked sequentially.

[0072] The driving circuit layer 13 is provided with a driving circuit for driving the light-emitting device 160. The driving circuit is located in the display area, and any driving circuit may include a transistor, which may be a thin-film transistor (TFT). The TFT may be selected from top-gate TFTs, bottom-gate TFTs, or dual-gate TFTs. Taking a top-gate TFT as an example, the driving circuit layer 13 may include a first active layer 131, a first gate insulating layer 1321, a first gate 1331 layer, a second gate insulating layer 1322, a second gate 1332 layer, and a first source / drain metal layer, sequentially disposed along a direction away from the substrate 11, wherein:

[0073] The first active layer 131 is disposed on one side of the substrate 11. The material of the first active layer 131 can be amorphous silicon semiconductor material, low-temperature polycrystalline silicon semiconductor material, metal oxide semiconductor material, organic semiconductor material, or other types of semiconductor material. Therefore, the thin film transistor can be an N-type thin film transistor or a P-type thin film transistor. The first active layer 131 may include a channel region and two doped regions of different doping types located on both sides of the channel region.

[0074] The first gate insulating layer 1321 is disposed on the side of the active layer 131 away from the substrate 11. The first gate insulating layer 1321 can cover the active layer 131 and the substrate 11. The first gate 1331 layer can include the first gate 1331. The first gate 1331 is disposed on the side of the first gate insulating layer 1321 away from the substrate 11 and is directly opposite to the active layer 131. That is, the projection of the first gate 1331 on the substrate 11 is located within the projection range of the active layer 131 on the substrate 11. For example, the projection of the first gate 1331 on the substrate 11 coincides with the projection of the channel region of the active layer 131 on the substrate 11. The second gate insulating layer 1322 is disposed on the side of the first gate 1331 away from the substrate 11. The second gate insulating layer 1322 can cover the first gate 1331 and the first gate insulating layer 1321. The second gate 1332 layer can include the second gate 1332, which is disposed on the side of the second gate insulating layer 1322 away from the substrate 11 and is directly opposite the active layer 131. The materials of the first gate insulating layer 1321 and the second gate insulating layer 1322 are both insulating materials such as silicon oxide.

[0075] The thin-film transistor may further include an interlayer dielectric layer 134, which is disposed on the side of the second gate 1332 away from the substrate 11, and may cover the second gate 1332 and the second gate insulating layer 1322. A first source / drain metal layer is disposed on the surface of the interlayer dielectric layer 134 away from the substrate 11, and may include a first source 135 and a drain 136, which are connected to the first active layer 131. For example, the first source 135 and the drain 136 are respectively connected to two doped regions of the corresponding first active layer 131 through vias. A protective layer 137 may also be provided on the side of the first source 135 away from the substrate 11, and the protective layer 137 covers the first source 135 and the drain 136. The driving circuit layer 13 may also include a planarization layer group 139, which includes a first planarization layer 1391. The first planarization layer 1391 is disposed on the side of the protective layer 137 away from the substrate 11, and the first planarization layer 1391 covers the protective layer 137.

[0076] The driving circuit layer 13 may further include a second source / drain metal layer, which is disposed on the side of the first planarization layer 1391 away from the substrate 11. The second source / drain metal layer may include a second source 138, which is connected to the first source 135. The planarization layer group 139 may further include a second planarization layer 1392, which is disposed on the side of the second source 138 away from the substrate 11. The second planarization layer 1392 covers the second source 138 and the first planarization layer 1391.

[0077] As shown in Figures 3 and 4, the display panel may further include a pixel defining layer 15 and a light-emitting layer 16. The pixel defining layer 15 is disposed on the side of the first planarization layer 1391 or the second planarization layer 1392 away from the array substrate. The pixel defining layer 15 includes a plurality of pixel defining portions 152, and a pixel opening 151 is formed between two adjacent pixel defining portions 152. The light-emitting layer 16 may include a plurality of light-emitting devices 160, which are respectively disposed in different pixel openings 151. Each light-emitting device 160 may include a pixel electrode 161, a light-emitting unit 162, and a common electrode 163. The pixel electrode 161 is located on the surface of the first planarization layer 1391 or the second planarization layer 1392 away from the substrate 11. The light-emitting unit 162 is disposed on the surface of the pixel electrode 161 away from the substrate 11, and the common electrode 163 is disposed on the surface of the light-emitting unit 162 away from the substrate 11. The light-emitting unit 162 can be driven to emit light through the pixel electrode 161 and the common electrode 163 to display an image.

[0078] Pixel electrode 161 is connected to either the first source 135 or the second source 138. A pixel defining layer 15 is provided on the side of pixel electrode 161 away from the substrate 11. When the thin-film transistor includes only the first source 135, pixel electrode 161 is connected to the first source 135, and pixel defining layer 15 covers pixel electrode 161 and the first planarization layer 1391. When the thin-film transistor also includes the second source 138, pixel electrode 161 is connected to the second source 138, and pixel defining layer 15 covers pixel electrode 161 and the second planarization layer 1392.

[0079] The common electrode 163 can serve as a cathode, and the pixel electrode 161 can serve as an anode. Light emission from the light-emitting unit 162 can be driven by applying a signal to the pixel electrode 161; the specific light emission principle will not be detailed here. The light-emitting unit 162 may contain an electroluminescent organic light-emitting material and can be formed using processes such as vapor deposition. For example, the light-emitting unit 162 may include a hole injection layer, a hole transport layer, a light generation layer, an electron transport layer, and an electron injection layer sequentially stacked on the pixel electrode 161.

[0080] Depending on the color of the emitted light, the light-emitting device 160 may include a first light-emitting device 1601, a second light-emitting device 1602, and a third light-emitting device 1603, each with a different color. In this embodiment, the first light-emitting device 1601 is red, the second light-emitting device 1602 is green, and the third light-emitting device 1603 is blue. In other embodiments, the first light-emitting device 1601 may also be green or blue, the second light-emitting device 1602 may also be blue or red, and the third light-emitting device 1603 may be red or green. These combinations can be made as needed and are not listed here.

[0081] Furthermore, the display panel of the present invention may also include an encapsulation layer 17, which is disposed on the side of the light-emitting layer 16 away from the substrate 11, thereby covering the light-emitting layer 16 and preventing water and oxygen corrosion. The encapsulation layer 17 may be a single-layer or multi-layer structure, and the material of the encapsulation layer 17 may include organic or inorganic materials, without special limitation. In this embodiment, the encapsulation layer 17 may include a first inorganic encapsulation layer 171, an organic encapsulation layer 172, and a second inorganic encapsulation layer 173. The first inorganic encapsulation layer 171 is disposed on the side of the light-emitting layer 16 away from the substrate 11, the organic encapsulation layer 172 is disposed on the side of the first inorganic encapsulation layer 171 away from the substrate 11, and the second inorganic encapsulation layer 173 is disposed on the side of the organic encapsulation layer 172 away from the substrate 11.

[0082] The display panel also includes a touch control layer 18, which can be a mutual capacitive touch control layer. The touch control layer 18 includes a first touch control layer 181 and a second touch control layer 182. The first touch control layer 181 is a metal mesh layer (MM), and the second touch control layer 182 is a bridge metal layer (BM). The metal mesh is located in the display area and can be divided into touch-driving (Tx) metal mesh and touch-sensing (Rx) metal mesh according to the horizontal and vertical directions. One of the touch-sensing (Rx) metal mesh and the touch-driving (Tx) metal mesh is interconnected, while the other is connected through the bridge metal layer.

[0083] A first tactile control layer 181 is disposed on the side of the substrate 11 away from the encapsulation layer 17, and a second tactile control layer 182 is disposed between the first tactile control layer 181 and the encapsulation layer 17. The tactile control layer 18 may further include a touch blocking layer 183 and a touch isolating layer 184, with the touch blocking layer 183 disposed between the encapsulation layer 17 and the second tactile control layer 182, and the touch isolating layer 184 disposed between the first tactile control layer 181 and the second tactile control layer 182. The tactile control layer 18 may further include a touch protection layer 185, disposed on the side of the first tactile control layer 181 away from the substrate 11.

[0084] The first touch control layer 181 may include a plurality of first touch units 1811, which are spaced apart. The orthographic projection of the first touch unit 1811 on the substrate 11 is located between the orthographic projections of two adjacent light-emitting devices 160 on the substrate 11. The second touch control layer 182 may include a plurality of second touch units 1821, whose orthographic projections on the substrate 11 overlap with the orthographic projections of the first touch units 1811 on the substrate 11.

[0085] As shown in Figures 5 to 7, the display panel further includes a color filter layer 19, which is disposed on the side of the touch protection layer 185 away from the driving backplate 10. The color filter layer 19 may include a first filter layer 191 and a second filter layer 192. The orthographic projection of the first filter layer 191 on the driving backplate 10 at least partially overlaps with the orthographic projection of the first light-emitting device 1601 on the driving backplate 10. The orthographic projection of the second filter layer 192 on the driving backplate 10 at least partially overlaps with the orthographic projections of the second light-emitting device 1602 and the third light-emitting device 1603 on the driving backplate 10. The overlapping of the orthographic projections of the first filter layer 191 and the second filter layer 192 on the driving backplate 10 forms a light-shielding area 1901.

[0086] The first filter layer 191 has a first light-transmitting opening 1911, and the second filter layer 192 has a second light-transmitting opening 1921. The first filter layer 191 is at least partially located within the second light-transmitting opening 1921. In this embodiment, the first filter layer 191 may block the second light-transmitting opening 1921. The orthographic projection of a light-emitting device 160 of one color on the driving back plate 10 is located within the orthographic projection of the second light-transmitting opening 1921 on the driving back plate 10. The orthographic projections of light-emitting devices 160 of other colors on the driving back plate 10 at least partially overlap with the orthographic projection of the first light-transmitting opening 1911 on the driving back plate 10. In this embodiment, the orthographic projections of light-emitting devices 160 of other colors on the driving back plate 10 may be located within the orthographic projection of the first light-transmitting opening 1911 on the driving back plate 10.

[0087] Multiple first filter sections 1912 and multiple second filter sections 1915 are formed as a whole, making the first filter layer 191 a mesh structure. A light-shielding area 1901 is disposed between adjacent first light-transmitting openings 1911, adjacent second light-transmitting openings 1921, and between adjacent first light-transmitting openings 1911 and second light-transmitting openings 1921. The orthographic projection of the first touch unit 1811 on the driving backplate 10 is located within the light-shielding area 1901. The orthographic projection of the light-shielding area 1901 on the driving backplate 10 at least partially overlaps with the orthographic projection of the pixel definition section 152 on the driving backplate 10. In this embodiment, the orthographic projection of the light-shielding area 1901 on the driving backplate 10 may be located within the orthographic projection of the pixel definition section 152 on the driving backplate 10.

[0088] As shown in Figures 4 to 7, the first light-emitting device 1601 and the third light-emitting device 1603 are arranged in a first pixel row along the row direction, and the second light-emitting device 1602 is arranged in a second pixel row along the row direction. The first pixel row and the second pixel row are alternately arranged along the column direction. The first light-emitting device 1601 is arranged in one column, the second light-emitting device 1602 is arranged in one column, and the third light-emitting device 1603 is arranged in one column. The second light-emitting device 1602 can be located in an odd-numbered column, and the first light-emitting device 1601 and the third light-emitting device 1603 can be located in an even-numbered column. The first light-emitting device 1601 and the third light-emitting device 1603 are alternately arranged in even-numbered columns.

[0089] As shown in Figures 8 to 11, compared to Figures 4 to 7, a photosensitive opening 198 can be set between two adjacent pixel openings 151. The photosensitive opening 198 does not have a first filter layer 191 or a second filter layer 192, which can ensure that ambient light enters the photosensitive device through the photosensitive opening 198, so that the brightness of the display panel can be adjusted according to the ambient light.

[0090] In other embodiments, the first light-emitting device 1601, the second light-emitting device 1602, and the third light-emitting device 1603 can also adopt an RGB arrangement: red, green, and blue pixels are arranged horizontally, and each pixel consists of a red, a green, and a blue highlight. This is the most common pixel arrangement. The first light-emitting device 1601, the second light-emitting device 1602, and the third light-emitting device 1603 can also adopt a Pentile arrangement: this arrangement is a subpixel arrangement that uses red, green, and blue subpixels, but adjacent pixels share green subpixels. The first light-emitting device 1601, the second light-emitting device 1602, and the third light-emitting device 1603 can also adopt a diamond arrangement, where each pixel still uses RG or BG, so the RGB pixel ratio is the same as in Pentile. This pixel arranges BG and GR in a diamond shape, hence the name diamond arrangement.

[0091] As shown in Figure 12, the first filter layer 191 includes a plurality of first filter portions 1912 and second filter portions 1915. The second filter layer 192 is disposed on the side of the touch protection layer 185 away from the driving backplate 10. The second filter layer 192 has a second light-transmitting opening 1921. The first filter portions 1912 fill the second light-transmitting opening 1921. The second filter portions 1915 and at least a portion of the first filter portions 1912 are disposed on the side of the second filter layer 192 away from the driving backplate 10. The portions of the second filter portions 1915 and the first filter portions 1912 that overlap on the second filter layer 192 form a light-shielding area 1901, which is opaque. A first light-transmitting opening 1911 is formed between the first filter portions 1912 and the second filter portions 1915, and between two adjacent second filter portions 1915.

[0092] As shown in Figure 13, the difference from Figure 12 is that the first filter layer 191 includes multiple first filter portions 1912 and second filter portions 1915. A first light-transmitting opening 1911 is formed between the first filter portions 1912 and the second filter portions 1915, and between two adjacent second filter portions 1915. The second filter layer 192 is disposed on the side of the first filter layer 191 away from the drive backplate 10. The second filter layer 192 covers the outer portions of the first filter portions 1912 and the second filter portions 1915. The second filter layer 192 has a second light-transmitting opening 1921 exposing the first filter portions 1912. The second filter layer 192 overlaps with the portions of the second filter portions 1915 and the first filter portions 1912 that do not expose the second light-transmitting opening 1921 to form a light-shielding area 1901. It can be understood that Figures 12 and 13 are due to the different manufacturing sequences of the first filter layer 191 and the second filter layer 192.

[0093] As shown in Figures 3-13, the first filter layer 191 can be a red filter layer, which transmits light in the red band. The second filter layer 192 has high transmittance in the blue and green bands. Correspondingly, the first light-emitting device 1601 can emit red light through the second light-transmitting opening 1921, and the second light-emitting device 1602 and the third light-emitting device 1603 can emit green and blue light through the first light-transmitting opening 1911.

[0094] The first filter layer 191 can also be a blue filter layer, which transmits light in the blue band. The second filter layer 192 has high transmittance in the red and green bands. Correspondingly, the third light-emitting device 1603 can emit blue light through the second light-transmitting opening 1921, and the first light-emitting device 1601 and the second light-emitting device 1602 can emit red and green light through the first light-transmitting opening 1911.

[0095] The first filter layer 191 can also be a green filter layer, which transmits light in the green band. The second filter layer 192 has high transmittance in the blue and red bands. Correspondingly, the second light-emitting device 1602 can emit green light through the second light-transmitting opening 1921, and the first light-emitting device 1601 and the third light-emitting device 1603 can emit red and blue light through the first light-transmitting opening 1911.

[0096] As shown in Figures 14 and 15, the orthographic projection of the first light-emitting device 1601 on the driving backplate 10 lies within the orthographic projection of the second light-transmitting opening 1921 on the driving backplate 10. The second light-transmitting opening 1921 contains only the first filter element 1912. The first filter layer 191 transmits the emitted light from the first light-emitting device 1601, thus red light can pass through the second light-transmitting opening 1921. The orthographic projections of the second light-emitting device 1602 and the third light-emitting device 1603 on the driving backplate 10 lie within the orthographic projection of the first light-transmitting opening 1911 on the driving backplate 10. The first light-transmitting opening 1911 contains only the second filter layer 192. The second filter layer 192 transmits the emitted light from the second light-emitting device 1602 and the third light-emitting device 1603, thus green and blue light can pass through the first light-transmitting opening 1911.

[0097] Figure 16 shows the transmittance spectrum curves of the second filter layer 192 when green and blue light pass through it. The second filter layer 192 has a first transmittance peak in the green light band (520-560 nm), where the transmittance is greater than 45%. In the red light band (600 nm-780 nm), the transmittance is less than 15%. The second filter layer 192 has a second transmittance peak in the blue light band (440-480 nm), where the transmittance is greater than 45%. The second filter layer 192 also exhibits a transmittance trough in the 500-520 nm range, where the transmittance is less than 40%.

[0098] As shown in Figures 3 to 14, the color filter layer 19 includes a color filter protective layer 193. The color filter protective layer 193 can be disposed on the side of the first filter layer 191 away from the driving backplate 10. The color filter protective layer 193 fills into the first light-transmitting opening 1911 and contacts the second filter layer 192 exposed in the first light-transmitting opening 1911. As shown in Figure 15, the color filter protective layer 193 can also be disposed on the side of the second filter layer 192 away from the driving backplate 10. The color filter protective layer 193 fills into the second light-transmitting opening 1921 and contacts the first filter layer 191 exposed in the second light-transmitting opening 1921.

[0099] As shown in Figures 17 and 18, the difference from Figures 14 and 15 is that the orthographic projection of the first filter layer 191 on the driving backplate 10 is the first orthographic projection, and the orthographic projection of the second filter layer 192 on the driving backplate 10 is the second orthographic projection. The first orthographic projection covers the orthographic projection of the second light-emitting device 1602 on the driving backplate 10, and the second orthographic projection covers the orthographic projections of the first light-emitting device 1601 and the third light-emitting device 1603 on the driving backplate 10. Specifically, the orthographic projection of the second light-emitting device 1602 on the driving backplate 10 is located within the orthographic projection of the second light-transmitting opening 1921 on the driving backplate 10, and the orthographic projections of the first light-emitting device 1601 and the third light-emitting device 1603 on the driving backplate 10 are located within the orthographic projection of the first light-transmitting opening 1911 on the driving backplate 10.

[0100] The first filter layer 191 transmits the emitted light from the second light-emitting device 1602, and the second filter layer 192 transmits the emitted light from the first light-emitting device 1601 and the third light-emitting device 1603. Therefore, green light can pass through the second light-transmitting opening 1921, and red and blue light can pass through the first light-transmitting opening 1911.

[0101] Figure 19 shows the transmission spectrum curves of the second filter layer 192 when red and blue light pass through it. The transmittance of the second filter layer 192 in the green light band (490nm-600nm) is less than 15%. The second filter layer 192 has a first transmittance peak in the red light band (580nm-780nm), and the transmittance of the second filter layer 192 at the first transmittance peak is greater than 45%. The second filter layer 192 has a second transmittance peak in the blue light band (440-480nm), and the transmittance of the second filter layer 192 at the second transmittance peak is greater than 45%.

[0102] As shown in Figures 20 and 21, the difference from Figures 14 and 15 is that the first orthographic projection covers the orthographic projection of the third light-emitting device 1603 on the driving backplate 10, and the second orthographic projection covers the orthographic projections of the first light-emitting device 1601 and the second light-emitting device 1602 on the driving backplate 10. Specifically, the orthographic projection of the third light-emitting device 1603 on the driving backplate 10 is located within the orthographic projection of the second light-transmitting opening 1921 on the driving backplate 10, and the orthographic projections of the first light-emitting device 1601 and the second light-emitting device 1602 on the driving backplate 10 are located within the orthographic projection of the first light-transmitting opening 1911 on the driving backplate 10.

[0103] The first filter layer 191 transmits the emitted light from the third light-emitting device 1603, and the second filter layer 192 transmits the emitted light from the first light-emitting device 1601 and the second light-emitting device 1602. Therefore, blue light can pass through the second light-transmitting opening 1921, and red and green light can pass through the first light-transmitting opening 1911.

[0104] Figure 22 shows the transmittance spectrum curves of the second filter layer 192 when red and green light pass through it. The second filter layer 192 has a first transmittance peak in the green light band (520-560 nm), with a transmittance greater than 45% at this peak. It also has a second transmittance peak in the red light band (580 nm-780 nm), with a transmittance greater than 45% at this peak. In the blue light band (380-490 nm), the transmittance of the second filter layer 192 is less than 15%. Finally, the second filter layer 192 has a transmittance trough in the 570-590 nm range, with a transmittance less than 20% at this trough.

[0105] As shown in Figure 23, when the first filter layer 191 transmits the emitted light from the third light-emitting device 1603, and the second filter layer 192 transmits the emitted light from the first light-emitting device 1601 and the second light-emitting device 1602, the transmittance of the light-shielding area 1901 for different wavelengths of light is less than or equal to 20%. Similarly, when the first filter layer 191 transmits the emitted light from the second light-emitting device 1602, and the second filter layer 192 transmits the emitted light from both the first and third light-emitting devices 1601 and 1603, the transmittance of the light-shielding area 1901 for different wavelengths of light is less than or equal to 20%.

[0106] The reflectivity and hue of the display panel can be adjusted by adjusting the thickness of the first filter layer 191 and the second filter layer 192. For example, when the thickness of the first filter layer 191 is fixed, the reflectivity and hue of the display panel can be adjusted by adjusting the thickness of the second filter layer 192. The following explanation uses the example of light emitted through the second light-emitting device 1602 via the first filter layer 191 and light emitted through the first light-emitting device 1601 and the third light-emitting device 1603 via the second filter layer 192.

[0107] When the thickness of the second filter layer 192 is 3 μm and the thickness of the first filter layer 191 varies between 2 and 3 μm, the reflectivity can vary between 6.9% and 7.5%; the hue coordinate a* can vary between -0.8 and 3.2, and the hue coordinate b* can vary between -4.8 and -2.7.

[0108] The reflectivity and hue of the display panel can also be adjusted by changing the aperture ratio of the light-transmitting openings corresponding to the first light-emitting device 1601, the second light-emitting device 1602, and the third light-emitting device 1603. When the aperture ratios of the first light-emitting device 1601, the second light-emitting device 1602, and the third light-emitting device 1603 remain constant, adjusting the aperture ratio of the light-transmitting openings corresponding to the first light-emitting device 1601, the second light-emitting device 1602, and the third light-emitting device 1603 can change the reflectivity between 0.5% and 15%, the hue coordinate a* can change between -10 and 10, and the hue coordinate b* can change between -10 and 10.

[0109] It should be noted that the first filter layer 191 transmits green light and the second filter layer 192 transmits red and blue light, as shown in Figures 20 and 21. Alternatively, the first filter layer 191 can transmit red light and the second filter layer 192 can transmit green and blue light, as shown in Figures 20 and 21. Or, the first filter layer 191 can transmit blue light and the second filter layer 192 can transmit red and green light.

[0110] In the above embodiments, the color filter layer 19 only requires the fabrication of a first filter layer 191 and a second filter layer 192, eliminating the need for a light-shielding layer 195 and one filter layer, thus saving two masking processes. Simultaneously, the display panel provided in this application embodiment has lower reflectivity, smaller hue deviation, a wider color gamut, and lower power consumption. Therefore, the display panel provided in this application embodiment saves on masking processes while avoiding hue deviation and ensuring a large color gamut.

[0111] As shown in Figure 24, the touch protection layer 185 has a first groove 1851 on the side away from the driving back plate 10. The orthographic projection of the first groove 1851 on the driving back plate 10 is located in the light-shielding area 1901, that is, the orthographic projection of the first groove 1851 on the color filter layer 19 is located between adjacent first light-transmitting openings 1911 and between adjacent first light-transmitting openings 1911 and second light-transmitting openings 1921. The orthographic projection of the first groove 1851 on the driving back plate 10 at least partially overlaps with the orthographic projection of the pixel definition part 152 on the driving back plate 10. In this embodiment, the orthographic projection of the first groove 1851 on the driving back plate 10 may be located within the orthographic projection of the pixel definition part 152 on the driving back plate 10.

[0112] The first filter section 1912 includes a first overlapping filter section 1913 and a first non-overlapping filter section 1914. The orthographic projection of the first non-overlapping filter section 1914 on the driving back plate 10 covers the orthographic projection of the second light-emitting device 1602 on the driving back plate 10. The orthographic projection of the first non-overlapping filter section 1914 on the driving back plate 10 can also cover the orthographic projection of the first light-emitting device 1601 or the third light-emitting device 1603 on the driving back plate 10. The first overlapping filter section 1913 and the second filter section 1915 are disposed in the first groove 1851. The side of the first overlapping filter section 1913 and the second filter section 1915 away from the driving back plate 10 can be lower than the side of the touch protection layer 185 away from the driving back plate 10, or flush with the side of the touch protection layer 185 away from the driving back plate 10, or higher than the side of the touch protection layer 185 away from the driving back plate 10.

[0113] The side of the first overlapping filter portion 1913 and the second filter portion 1915 away from the driving back plate 10 is lower than the side of the first non-overlapping filter portion 1914 away from the driving back plate 10. The second filter layer 192 is disposed on the side of the touch protection layer 185, the first overlapping filter portion 1913 and the second filter portion 1915 away from the driving back plate 10. The side of the second filter layer 192 away from the driving back plate 10 is flush with the side of the first non-overlapping filter portion 1914 away from the driving back plate 10.

[0114] It should be noted that "aligned" here refers to being basically aligned, allowing for a certain margin of error. There is a height difference of ±1 μm between the side of the second filter layer 192 away from the driving backplate 10 and the side of the first non-overlapping filter 1914 away from the driving backplate 10. That is, the side of the second filter layer 192 away from the driving backplate 10 is 1 μm lower than the side of the first non-overlapping filter 1914 away from the driving backplate 10, or alternatively, the side of the second filter layer 192 away from the driving backplate 10 is 1 μm higher than the side of the first non-overlapping filter 1914 away from the driving backplate 10.

[0115] As shown in Figure 25, the difference from Figure 24 is that the second filter layer 192 includes a second overlapping filter portion 1923 and a second non-overlapping filter portion 1922. The orthographic projection of the second non-overlapping filter portion 1922 on the driving back plate 10 is the orthographic projection of the second light-emitting device 1602 on the driving back plate 10. The orthographic projection of the second non-overlapping filter portion 1922 on the driving back plate 10 can also cover the orthographic projection of the first light-emitting device 1601 or the third light-emitting device 1603 on the driving back plate 10. The second overlapping filter portion 1923 is disposed in the first groove 1851. The side of the second overlapping filter portion 1923 away from the driving back plate 10 can be lower than the side of the touch protection layer 185 away from the driving back plate 10, or flush with the side of the touch protection layer 185 away from the driving back plate 10, or higher than the side of the touch protection layer 185 away from the driving back plate 10.

[0116] The side of the second overlapping filter portion 1923 away from the driving back plate 10 is lower than the side of the second non-overlapping filter portion 1922 away from the driving back plate 10. The first filter layer 191 is disposed on the side of the touch protection layer 185 and the side of the second overlapping filter portion 1923 away from the driving back plate 10. The side of the first filter layer 191 away from the driving back plate 10 is flush with the side of the second non-overlapping filter portion 1922 away from the driving back plate 10.

[0117] By using a half-tone mask (HTM) to etch the touch protection layer 185, when the second filter layer 192 is located on the side of the first filter layer 191 away from the driving backplate 10, the portion of the first filter 1912 located in the light-shielding area 1901 and the second filter 1915 are disposed within the first groove 1851. When the first filter layer 191 is located on the side of the second filter layer 192 away from the driving backplate 10, the portion of the second filter layer 192 located in the light-shielding area 1901 is disposed within the first groove 1851. This allows the side of the first filter layer 191 away from the driving backplate 10 and the side of the second filter layer 192 away from the driving backplate 10 to be on the same plane, eliminating the need for the color filter protection layer 193, saving another masking process, and reducing the manufacturing cost of the display panel.

[0118] As shown in Figure 26, the second filter layer 192 can be directly disposed on the side of the first touch unit 1811 away from the driving backplate 10 to protect the first touch control layer 181. The advantage of this display panel is that it eliminates the need for a separate touch protection layer 185, reducing the thickness of the display panel. Compared to the display panels in Figures 3 to 25, it saves another masking process, lowering the manufacturing cost of the display panel. It should be noted that the structure in Figure 26 where the touch protection layer 185 is removed and the second filter layer 192 protects the first touch control layer 181 is applicable to all embodiments in Figures 3 to 25, and will not be described in detail here.

[0119] As shown in Figures 27 and 28, the color filter layer 19 can be disposed between the touch layer group and the encapsulation layer group 17. As shown in Figure 27, the second filter layer 192 can be disposed on the side of the second inorganic encapsulation layer 173 away from the driving backplate 10, the first filter layer 191 can be disposed on the side of the second filter layer 192 away from the driving backplate 10, the color filter protective layer 193 can be disposed on the side of the first filter layer 191 away from the driving backplate 10, and the touch control layer 18 can be disposed on the side of the color filter protective layer 193 away from the driving backplate 10. As shown in Figure 28, the first filter layer 191 can also be disposed on the side of the second inorganic encapsulation layer 173 away from the driving backplate 10, the second filter layer 192 can be disposed on the side of the first filter layer 191 away from the driving backplate 10, the color filter protective layer 193 can be disposed on the side of the second filter layer 192 away from the driving backplate 10, and the touch control layer 18 can be disposed on the side of the color filter protective layer 193 away from the driving backplate 10. The advantage of the display panels in Figures 27 and 28 is that the touch blocking layer 183 can be omitted, the thickness of the display panel can be reduced, and compared with the display panels in Figures 3 to 25, another mask process is saved, reducing the manufacturing cost of the display panel.

[0120] The structural and positional relationships of the first filter layer 191 and the second filter layer 192 in Figures 3 to 25 can be applied to Figures 27 and 28. The structural and positional relationships of the first filter layer 191 and the second filter layer 192 in Figures 27 and 28 can be referenced from Figures 3 to 25.

[0121] As shown in Figure 29, the color filter layer 19 is disposed between the first inorganic encapsulation layer 171 and the second inorganic encapsulation layer 173. Multiple recesses 1711 are formed on the side of the first inorganic encapsulation layer 171 away from the driving backplate 10. The orthographic projection of the recesses 1711 on the driving backplate 10 overlaps with the orthographic projection of the light-emitting device 160 on the driving backplate 10. A first filter layer 191 is disposed on the side of the first inorganic encapsulation layer 171 away from the driving backplate 10, and the first filter layer 191 fills the second light-emitting device 160. The first light-emitting device 1601 and the third light-emitting device 1603 have corresponding recesses 1711. The second filter layer 192 is disposed on the side of the first filter layer 191 away from the driving backplate 10. The second filter layer 192 fills the recesses 1711 corresponding to the first light-emitting device 1601 and the third light-emitting device 1603. That is, the recesses 1711 corresponding to the second light-emitting device 1602 correspond to the second light-transmitting opening 1921, and the recesses 1711 corresponding to the first light-emitting device 1601 and the third light-emitting device 1603 correspond to the first light-transmitting opening 1911. The organic encapsulation layer 172 is disposed on the side of the first filter layer 191 away from the driving backplate 10. The organic encapsulation layer 172 fills the first light-transmitting opening 1911 and contacts the second filter layer 192 exposed in the first light-transmitting opening 1911.

[0122] As shown in Figure 30, the difference from Figure 29 is that a plurality of recesses 1711 are formed on the side of the first inorganic encapsulation layer 171 away from the driving backplate 10. The orthographic projection of the recesses 1711 on the driving backplate 10 overlaps with the orthographic projection of the light-emitting device 160 on the driving backplate 10. The second filter layer 192 is disposed on the side of the first inorganic encapsulation layer 171 away from the driving backplate 10 and fills the recesses 1711 corresponding to the light-emitting devices 160 of other colors. The first filter layer 191 is disposed on the side of the second filter layer 192 away from the driving backplate 10 and fills the recesses 1711 corresponding to the light-emitting devices 160 of one color. The organic encapsulation layer 172 is disposed on the side of the first filter layer 191 away from the driving backplate 10 and fills the second light-transmitting opening 1921, contacting the first filter layer 191 exposed in the second light-transmitting opening 1921.

[0123] In this embodiment, compared to the display panels in Figures 3 to 25, omitting the color filter protective layer 193 can still reduce the thickness of the display panel, further saving a masking process and reducing the manufacturing cost of the display panel. Additionally, the color filter layer 19 can play a certain filling role, thus reducing the thickness of the organic encapsulation layer 172. It is understood that this embodiment can further reduce the thickness of the display panel.

[0124] The structure and positional relationship between the first filter layer 191 and the second filter layer 192 in Figures 3 to 25 can be applied to Figures 29 and 30. The structure and positional relationship between the first filter layer 191 and the second filter layer 192 in Figures 29 and 30 can be referenced from Figures 3 to 25.

[0125] It should be noted that Figures 24 to 30 can also be adjusted so that: the first filter layer 191 transmits red light emitted by the first light-emitting device 1601 through the first light-transmitting opening 1911, and the second filter layer 192 transmits green and blue light emitted by the second light-emitting device 1602 and the third light-emitting device 1603 through the second light-transmitting opening 1921. Alternatively, the first filter layer 191 transmits blue light emitted by the third light-emitting device 1603 through the first light-transmitting opening 1911, and the second filter layer 192 transmits red and green light emitted by the first light-emitting device 1601 and the second light-emitting device 1602 through the second light-transmitting opening 1921.

[0126] It should be noted that in the above embodiments, when the second filter layer 192 transmits green and blue light, the color of the second filter layer 192 is cyan; when the second filter layer 192 transmits red and blue light, the color of the second filter layer 192 is purple; and when the second filter layer 192 transmits red and green light, the color of the second filter layer 192 is yellow.

[0127] It should be noted that the superposition is not limited to the first filter layer 191 and the second filter layer 192. Other color filter layers can also be superimposed. For example, when the first filter layer 191 transmits green light emitted by the second light-emitting device 1602, another filter layer can be provided that transmits red light emitted by the first light-emitting device 1601 or blue light emitted by the third light-emitting device 1603. The orthographic projection of this other filter layer on the drive backplate 10 overlaps with the orthographic projections of the first overlapping filter portion 1913 and the second filter portion 1915 on the drive backplate 10. To ensure the light-shielding effect of the light-shielding area 1901, the other filter layer can be replaced with a light-shielding layer 195, which is opaque. The other filter layer or light-shielding layer 195 can be located on the upper surface of a layer of the first filter layer 191 and the second filter layer 192 that is away from the drive backplate 10, or it can be located between the first filter layer 191 and the second filter layer 192.

[0128] The present invention also provides a display panel. As shown in Figure 31, the display panel may include a driving backplate 10, a light-emitting layer 16, and a color filter layer 19. The light-emitting layer 16 is disposed on one side of the driving backplate 10 and includes at least three different colored light-emitting devices 160. The color filter layer 19 includes a light-shielding layer 195, a first light-filtering layer 191, and a second light-filtering layer 192. The orthographic projection of the first light-filtering layer 191 on the driving backplate 10 at least partially overlaps with the orthographic projection of one colored light-emitting device 160 on the driving backplate 10. The orthographic projection of the second light-filtering layer 192 on the driving backplate 10 at least partially overlaps with the orthographic projection of the other colored light-emitting devices 160 on the driving backplate 10. The light-shielding layer 195 and the second light-filtering layer 192 overlap in a direction perpendicular to the driving backplate 10 to form a light-shielding area 1901. The first light-filtering layer 191 transmits the emitted light of one colored light-emitting device 160, and the second light-filtering layer 192 transmits the emitted light of the other colored light-emitting devices 160.

[0129] The color filter layer 19 includes a first light filter layer 191, a second light filter layer 192, and a light-shielding layer 195. The first light filter layer 191 transmits light emitted from the light-emitting device 160 of one color, while the second light filter layer 192 transmits light emitted from the light-emitting device 160 of other colors. The light-shielding layer 195 and the second light filter layer 192 overlap in a direction perpendicular to the driving backplate 10 to form a light-shielding area 1901. Manufacturing the color filter layer 19 requires only three masking processes: the first light filter layer 191, the second light filter layer 192, and the light-shielding layer 195. Compared to a four-mask process, this reduces the number of masking processes required to manufacture the color filter layer 19, thus lowering the manufacturing cost of the display panel.

[0130] The light-shielding layer 195 is disposed on the side of the second filter layer 192 away from the driving back plate 10 or on the side close to the driving back plate 10. That is, the light-shielding layer 195 can be disposed between the second filter layer 192 and the touch protection layer 185, or the light-shielding layer 195 can be disposed between the second filter layer 192 and the color filter protection layer 193.

[0131] Alternatively, light-emitting openings 1951 can be provided on the light-shielding layer 195, and the area between the light-emitting openings 1951 is the light-shielding area 1901. The area where the light-shielding layer 195 is retained is the light-shielding area 1901. The second filter layer 192 is only formed in the light-emitting openings 1951 corresponding to the first light-emitting device 1601 and the light-emitting openings 1951 corresponding to the third light-emitting device 1603. Compared with the four-mask process, the color filter layer 19 of this display panel can also save one mask process.

[0132] This invention also provides a display device, which may include the display panel described in any of the above embodiments of this invention. The specific structure and beneficial effects of the display panel have already been described in detail above, and therefore will not be repeated here.

[0133] It should be noted that, in addition to the display panel, the display device also includes other necessary components and parts, such as the casing, circuit board, power cord, etc. Those skilled in the art can make corresponding additions according to the specific usage requirements of the display device, which will not be elaborated here.

[0134] Display devices can also be emerging wearable devices, such as virtual reality and augmented reality devices, or traditional electronic devices, such as mobile phones, computers, televisions, and video recorders. These will not be listed exhaustively here.

This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
