In addition, the drawings are only schematic illustrations of the present utility model and are not necessarily drawn to scale.

[0067] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of an icon to another component, these terms are used in this specification only for convenience, for example, according to the directions of the examples described in the drawings. It can be understood that if the device of the icon is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" another structure, it may mean that a structure is integrally formed on another structure, or that a structure is "directly" disposed on another structure, or that a structure is "indirectly" disposed on another structure through another structure.

[0068] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to mean an open inclusion and refer to the possibility of the existence of additional elements / components / etc. in addition to the recited elements / components / etc.; the terms "first", "second", "third", etc. are used only as labels and do not limit the quantity of their objects.

[0069] The FMLOC (Flexible multi-Layer On Cell) design is currently the mainstream in the field of OLED touch displays. The FMLOC design means that a metal electrode layer is fabricated on the encapsulation layer 17 of the display substrate, and the surface of the metal electrode layer reflects ambient light significantly. In order to improve the contrast of the display panel and reduce the reflected light, a polarizer is usually disposed on the light-emitting side of the light-emitting layer 16 so that the display panel appears black when it is not lit. However, the polarizer will cause attenuation of the light intensity of the display panel and increase the thickness of the display panel.

[0070] As Figure 1 shown, in order to improve the light extraction efficiency of the display panel at the normal viewing angle and reduce the thickness of the display panel, a first covering layer 191 is disposed on the side of the touch electrode layer away from the substrate 11. The first covering layer 191 includes a plurality of first covering portions 1911. The touch electrode layer includes a plurality of touch units. The first covering portion 1911 is disposed on the side of the first touch unit 1811 away from the substrate 11. The first covering portion 1911 covers the first touch unit 1811. A dimming opening 1912 is formed between the sides of the first covering portions 1911 that are close to each other. A light-shielding layer 192 is disposed on the side of the first covering layer 191 away from the substrate 11. The light-shielding layer 192 includes a plurality of light-shielding portions 1921. A light-transmitting opening 1922 is formed between the sides of the light-shielding portions 1921 that are close to each other. Different color filter units 193 are disposed in each dimming opening 1912. The filter units 193 cover the side surfaces of the first covering portions 1911 and extend to the side of the first covering portions 1911 away from the substrate 11.

[0071] Since the width and thickness of the first touch unit 1811 are small, the side surface of the first covering portion 1911 is an inclined surface. The refractive index of the filter unit 193 is greater than that of the first covering portion 1911. Therefore, the light rays emitted at an oblique viewing angle of the light-emitting unit 162 can undergo total internal reflection at the interface between the side surface of the first covering portion 1911 and the filter unit 193, deflecting the light rays emitted at an oblique viewing angle to be emitted in the direction of the normal viewing angle, improving the light extraction efficiency of the display panel at the normal viewing angle. Therefore, there is no need to provide a polarizer, reducing the thickness of the display panel and facilitating the thinning of the display panel.

[0072] As Figure 2As shown, the orthographic projection of the dimming opening 1912 on the driving backplane 10 is located within the orthographic projection of the light-transmitting opening 1922 on the driving backplane 10, and the center of the orthographic projection of the dimming opening 1912 on the driving backplane 10 coincides with the center of the orthographic projection of the light-transmitting opening 1922 on the driving backplane 10. As Figure 3 and Figure 4 shown, because the reflection light of the ambient light has frequencies close to those of the light-transmitting opening 1922 and the dimming opening 1912, in the case of poor matching, the light wave S1 of the ambient light reflection light in the light-transmitting opening 1922 and the light wave S2 of the dimming opening 1912 are superimposed. The waveforms of the two light waves are superimposed at the wave crests, and the interference results in brighter optical fringes. The wave crests and wave troughs of the two light waves are superimposed, and the interference results in darker optical fringes. Therefore, optical interference easily causes stripe defects with alternating light and dark.

[0073] Based on this, an embodiment of the present utility model provides a display panel. As Figures 5 to 22As shown, the display panel includes a driving backplane 10, a pixel defining layer 15, a plurality of pixel electrodes 161, a plurality of light-emitting units 162 of different colors, a common electrode 163, a first cover layer 191, a color filter layer, and a light-shielding layer 192.

The orthographic projection of the dimming opening 1912 on the driving backplane 10 is located within the orthographic projection of the light-transmitting opening 1922 on the driving backplane 10. The light-transmitting opening 1922 has a first portion 1926 and a second portion 1927.

The light-transmitting opening 1922 has a first portion 1926 and a second portion 1927. The distance between the first portion 1926 and the edge of the dimming opening 1912 is a first distance, and the distance between the second portion 1927 and the edge of the dimming opening 1912 is a second distance. The first distance is not equal to the second distance, causing the centroids of the light-transmitting opening 1922 and the dimming opening 1912 to be misaligned, which can change the frequency relationship of the reflected light of the ambient light between the light-transmitting opening 1922 and the dimming opening 1912, avoiding the possibility of interference between the light waves of the reflected light of the ambient light in the light-transmitting opening 1922 and the light waves of the dimming opening 1912, thereby eliminating the stripe defect of the display screen.

[0075] The following will specifically describe the display panel involved in the embodiment of the present utility model in conjunction with specific embodiments.

[0076] As Figure 5 shown, the display panel generally may include a substrate substrate 11 and a driving circuit layer 13. The driving circuit layer 13 is disposed on one side of the substrate substrate 11. The display panel may further include a buffer layer 12, and the buffer layer 12 is disposed between the substrate substrate 11 and the driving circuit layer 13.

[0077] The substrate substrate 11 may be a substrate substrate 11 made of inorganic materials or a substrate substrate 11 made of organic materials. For example, in an embodiment of the present utility model, the material of the substrate substrate 11 may be glass materials such as soda-lime glass, quartz glass, sapphire glass, or may be metal materials such as stainless steel, aluminum, nickel, etc.

[0078] In another embodiment of the present utility model, the substrate substrate 11 may also be a flexible substrate substrate 11. For example, the material of the substrate substrate 11 may be polyimide (PI). The substrate substrate 11 may also be a composite of multiple layers of materials. For example, in an embodiment of the present utility model, the substrate substrate 11 may include a bottom film layer (Bottom Film), a pressure-sensitive adhesive layer, a first polyimide layer, and a second polyimide layer that are sequentially stacked.

The material of the first active layer 131 may be an amorphous silicon semiconductor material, a low-temperature polycrystalline silicon semiconductor material, a metal oxide semiconductor material, an organic semiconductor material, or other types of semiconductor materials. Therefore, the thin-film transistor may 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.

[0081] The first gate insulating layer 1321 is disposed on the side of the active layer 131 away from the substrate 11.

The first gate electrode 1331 is disposed on the side of the first gate insulating layer 1321 away from the substrate 11 and is opposite to the active layer 131, that is, the projection of the first gate electrode 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 electrode 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 electrode 1331 away from the substrate 11.

The materials of the first gate insulating layer 1321 and the second gate insulating layer 1322 are both insulating materials such as silicon oxide.

[0082] The thin film transistor may further include an interlayer dielectric layer 134 disposed on a side of the second gate 1332 away from the substrate 11. The interlayer dielectric layer 134 may cover the second gate 1332 and the second gate insulating layer 1322. The first source-drain metal layer is disposed on a surface of the interlayer dielectric layer 134 away from the substrate 11, and the first source-drain metal layer may include a first source electrode 135 and a drain electrode 136. The first source electrode 135 and the drain electrode 136 are connected to the first active layer 131. For example, the first source electrode 135 and the drain electrode 136 are respectively connected to two doped regions of the corresponding first active layer 131 through vias. A protective layer 137 may be disposed on a side of the first source electrode 135 away from the substrate 11, and the protective layer 137 covers the first source electrode 135 and the drain electrode 136. The driving circuit layer 13 may further include a planarization layer group 139. The planarization layer group 139 includes a first planarization layer 1391 disposed on a side of the protective layer 137 away from the substrate 11, and the first planarization layer 1391 covers the protective layer 137.

[0083] The driving circuit layer 13 may further include a second source-drain metal layer disposed on a side of the first planarization layer 1391 away from the substrate 11. The second source-drain metal layer may include a second source electrode 138. The second source electrode 138 is connected to the first source electrode 135.

The light emitting layer 16 may include a plurality of light emitting units 162, and the plurality of light emitting units 162 are respectively disposed in different pixel openings 151. Each light emitting unit 162 may include a pixel electrode 161, a light emitting unit 162, and a common electrode 163. The pixel electrode 161 is located on a 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 a surface of the pixel electrode 161 away from the substrate 11. The common electrode 163 is disposed on a 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.

[0085] The pixel electrode 161 is connected to the first source electrode 135 or the second source electrode 138. A pixel defining layer 15 is provided on the side of the pixel electrode 161 away from the substrate 11. When the thin film transistor only includes the first source electrode 135, the pixel electrode 161 is connected to the first source electrode 135, and the pixel defining layer 15 covers the pixel electrode 161 and the first planarization layer 1391. When the thin film transistor further includes the second source electrode 138, the pixel electrode 161 is connected to the second source electrode 138, and the pixel defining layer 15 covers the pixel electrode 161 and the second planarization layer 1392.

[0086] The common electrode 163 can be used as the cathode, and the pixel electrode 161 can be used as the anode. The light-emitting unit 162 can be driven to emit light by applying a signal to the pixel electrode 161. The specific light-emitting principle will not be elaborated here. The light-emitting unit 162 can contain an electro-organic light-emitting material and can be formed by processes such as evaporation coating. For example, the light-emitting unit 162 can include a hole injection layer, a hole transport layer, a light generation layer, an electron transport layer, and an electron injection layer that are sequentially stacked on the pixel electrode 161. It should be noted that according to different emission colors, the light-emitting unit 162 can include a first light-emitting unit 1621, a second light-emitting unit 1622, and a third light-emitting unit 1623.

[0087] In addition, the display panel of the present utility model may further include a packaging layer 17. The packaging layer 17 is provided on the side of the light-emitting layer 16 away from the substrate 11, so as to wrap the light-emitting layer 16 and prevent water and oxygen from eroding. The packaging layer 17 can be a single-layer or multi-layer structure, and the material of the packaging layer 17 can include organic or inorganic materials, which are not specifically limited here. In this embodiment, the packaging layer 17 can include a first inorganic packaging layer 171, an organic packaging layer 172, and a second inorganic packaging layer 173.

Among them, 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 (Metal Mesh, MM), and the second touch control layer 182 is a bridge metal layer (Bridge Metal, BM). The metal mesh is located in the display area, and the metal mesh can be divided into a touch drive (Tx) metal mesh and a touch sensing (Rx) metal mesh in the horizontal and vertical directions. Among them, one of the touch sensing (Rx) metal mesh and the touch drive (Tx) metal mesh is connected to each other, and the other is connected through the bridge metal layer.

[0089] The first touch control layer 181 is disposed on the side of the substrate 11 away from the encapsulation layer 17, and the second touch control layer 182 is disposed between the first touch control layer 181 and the encapsulation layer 17. The touch control layer 18 may further include a touch blocking layer 183 and a touch isolation layer 184. The touch blocking layer 183 is disposed between the encapsulation layer 17 and the second touch control layer 182, and the touch isolation layer 184 is disposed between the first touch control layer 181 and the second touch control layer 182.

[0090] The first touch control layer 181 may include a plurality of first touch units 1811, and the plurality of first touch units 1811 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 units 162 on the substrate 11. The second touch control layer 182 may include a plurality of second touch units 1821, and the orthographic projection of the second touch unit 1821 on the substrate 11 overlaps with the orthographic projection of the first touch unit 1811 on the substrate 11.

[0091] As Figure 5 shown, the display panel may further include a light regulation layer 19. The light regulation layer 19 includes a first covering layer 191. The first covering layer 191 includes a plurality of first covering portions 1911. The first covering portions 1911 are disposed on the side of the first touch unit 1811 away from the substrate 11. The first covering portions 1911 cover the first touch units 1811. A dimming opening 1912 is formed between two adjacent first covering portions 1911. The slope angle of the side surface of the first covering portion 1911 is less than 90 degrees.

[0092] The light regulation layer 19 may further include a light shielding layer 192. The light shielding layer 192 includes a plurality of light shielding portions 1921. The light shielding portions 1921 are disposed on the side of the first covering portion 1911 away from the driving backplane 10. The orthographic projection of the light shielding portion 1921 on the substrate 11 covers the orthographic projection of the first touch unit 1811 on the substrate 11, that is, the orthographic projection of the first touch unit 1811 on the substrate 11 is located within the orthographic projection of the light shielding portion 1921 on the substrate 11, and the area of the orthographic projection of the first touch unit 1811 on the substrate 11 is smaller than the area of the orthographic projection of the light shielding portion 1921 on the substrate 11. A light transmission opening 1922 is formed between the sides of the light shielding portions 1921 that are close to each other. The orthographic projection of the dimming opening 1912 on the substrate 11 is located within the orthographic projection of the light transmission opening 1922 on the substrate 11.

[0093] The light control layer 19 may further include a filter layer. The filter layer includes filter units 193 of different colors. The filter units 193 are disposed in the dimming openings 1912 formed between two adjacent first covering portions 1911. The thickness of the filter units 193 is greater than that of the first covering portions 1911. The filter units 193 cover the side surfaces of the first covering portions 1911 and a partial area of the light shielding portion 1921 disposed on the side of the first covering portions 1911 away from the substrate 11. The non-overlapping portion of the first covering portions 1911 with the filter units 193 is the exposed area. The light shielding portion 1921 is disposed in the exposed area, and the distance between the light shielding portion 1921 and the filter units 193 is greater than 0. The display panel may further include a second covering layer 20. The second covering layer 20 covers the side of the filter units 193 and the light shielding portion 1921 away from the substrate 11, and the gap formed between the filter units 193 and the light shielding portion 1921.

[0094] The filter units 193 of different colors include a first filter unit 1931, a second filter unit 1932, and a third filter unit 1933. The orthographic projection of the first filter unit 1931 on the substrate 11 covers the orthographic projection of the first light-emitting unit 1621 on the substrate 11. The orthographic projection of the second filter unit 1932 on the substrate 11 covers the orthographic projection of the second light-emitting unit 1622 on the substrate 11. The orthographic projection of the third filter unit 1933 on the substrate 11 covers the orthographic projection of the third light-emitting unit 1623 on the substrate 11.

[0095] The first covering portions 1911 may be made of a low-refractive-index resin material with a refractive index of 1.45 - 1.5. The refractive index of the first filter unit 1931 is generally 1.65 - 1.85, and the refractive indices of the second filter unit 1932 and the third filter unit 1933 are generally 1.55 - 1.7. The refractive indices of the three-color filter units 193 are all higher than that of the first covering portions 1911. Therefore, the reflected light of the ambient light at an oblique viewing angle can undergo total internal reflection on the side surfaces of the first covering portions 1911, deflect and exit in the direction of the normal viewing angle, improving the light extraction efficiency at the normal viewing angle.

[0096] The display panel uses the first covering portions 1911 to insulate the first touch units 1811, which can reduce the thickness of the display panel. The outgoing light at an oblique viewing angle can undergo total internal reflection on the side surfaces of the first covering portions 1911, deflect and exit in the direction of the normal viewing angle, improving the light extraction efficiency at the normal viewing angle without production capacity loss. Secondly, the shape of the first covering portions 1911 is trapezoidal, and its side surfaces are conventional inclined surfaces, and the slope angle is easier to control.

[0097] The distance between the first part 1926 and the edge of the dimming opening 1912 is the first distance, and the distance between the second part 1927 and the edge of the dimming opening 1912 is the second distance. The first distance is not equal to the second distance. Dislocating the light-transmitting opening 1922 from the centroid of the dimming opening 1912 can change the frequency relationship of the reflected light of the ambient light between the light-transmitting opening 1922 and the dimming opening 1912, avoiding the possibility of interference between the light waves of the reflected light of the ambient light in the light-transmitting opening 1922 and the light waves of the dimming opening 1912, thereby eliminating the stripe defect of the display screen.

[0098] In this embodiment, the first part 1926 of the light-transmitting opening 1922 can protrude relative to the second part 1927, such that the first distance is greater than the second distance. As Figures 6 to 22 shown, the first part 1926 of the first light-transmitting opening 1923 protrudes relative to the second part 1927, the first part 1926 of the second light-transmitting opening 1924 protrudes relative to the second part 1927, and the first part 1926 of the third light-transmitting opening 1925 protrudes relative to the second part 1927. In other embodiments, the first part 1926 of the light-transmitting opening 1922 can also be concave relative to the second part 1927, such that the first distance is less than the second distance.

[0099] The shape of the dimming opening 1912 is similar to the shape of the pixel opening 151, and the center of the dimming opening 1912 coincides with the center of the pixel opening 151. It should be noted that being similar in shape means that the shape of the dimming opening 1912 is basically the same as the shape of the pixel opening 151, only the sizes are different. For example: when the dimming opening 1912 is circular, the shape of the light-transmitting opening 1922 is a circle surrounding the pixel opening 151; when the dimming opening 1912 is triangular, the shape of the light-transmitting opening 1922 is a triangle surrounding the pixel opening 151; when the dimming opening 1912 is oval, the shape of the light-transmitting opening 1922 is an oval surrounding the pixel opening 151.

[0100] The light-transmitting opening 1922 has a first part 1926 and a second part 1927, and the shape of the second part 1927 of the light-transmitting opening 1922 is similar to the shape of the dimming opening 1912 at the corresponding position. It should be noted that being similar in shape means that the shape of the light-transmitting opening 1922 is basically the same as the shape of the second part 1927 of the light-transmitting opening 1922, only the sizes are different. For example: when the dimming opening 1912 is circular, the shape of the second part 1927 of the light-transmitting opening 1922 is a circle with a notch; when the dimming opening 1912 is triangular, the shape of the second part 1927 of the light-transmitting opening 1922 is a triangle with a notch; when the dimming opening 1912 is oval, the shape of the second part 1927 of the light-transmitting opening 1922 is an oval with a notch.

The at least three light-transmitting openings 1922 include a first light-transmitting opening 1923, a second light-transmitting opening 1924, and a third light-transmitting opening 1925. The first covering layer 191 is provided with at least three light-dimming openings 1912. The light-dimming openings 1912 include a first light-dimming opening 1913, a second light-dimming opening 1914, and a third light-dimming opening 1915. The orthographic projection of the first light-dimming opening 1913 on the driving backplane 10 is located within the orthographic projection of the first light-transmitting opening 1923 on the substrate 11. The orthographic projection of the second light-dimming opening 1914 on the driving backplane 10 is located within the orthographic projection of the second light-transmitting opening 1924 on the substrate 11. The orthographic projection of the third light-dimming opening 1915 on the driving backplane 10 is located within the orthographic projection of the third light-transmitting opening 1925 on the substrate 11. The first light-filtering unit 1931 is disposed within the first light-dimming opening 1913 and the first light-transmitting opening 1923. The second light-filtering unit 1932 is disposed within the second light-dimming opening 1914 and the second light-transmitting opening 1924. The third light-filtering unit 1933 is disposed within the third light-dimming opening 1915 and the third light-transmitting opening 1925.

[0102] The light-shielding layer 192 is provided with m groups of light-transmitting openings 1922 extending along the first direction and arranged along the second direction, and n groups of light-transmitting openings 1922 extending along the second direction and arranged along the first direction. The mth group of light-transmitting openings 1922 is divided into two rows, and the two rows of light-transmitting openings 1922 are staggered. One row of light-transmitting openings 1922 is an alternately arranged first light-transmitting opening 1923 and third light-transmitting opening 1925, and the other row is the second light-transmitting opening 1924. The second light-transmitting opening 1924 is located between the first light-transmitting opening 1923 and the third light-transmitting opening 1925 along the first direction; the nth group of light-transmitting openings 1922 is divided into two columns, and the two columns of light-transmitting openings 1922 are staggered. One column of light-transmitting openings 1922 is an alternately arranged first light-transmitting opening 1923 and third light-transmitting opening 1925, and the other column is the second light-transmitting opening 1924. The second light-transmitting opening 1924 is located between the first light-transmitting opening 1923 and the third light-transmitting opening 1925 along the second direction.

[0103] The size of all the first light-transmitting openings 1923 in the first direction may be equal to the size in the second direction. The size of the second light-transmitting opening 1924 in the first direction may be equal to the size in the second direction. In the mth o group of light-transmitting openings 1922, the size of the third light-transmitting opening 1925 in the first direction is smaller than the size in the second direction. The third light-transmitting opening 1925 is symmetrically arranged with respect to the first direction, and the orientations of two adjacent third light-transmitting openings 1925 in the first direction are opposite. In the mth eThe third light-transmitting opening 1925 among the group of light-transmitting openings 1922 has a dimension in the first direction that is greater than its dimension in the second direction. The third light-transmitting openings 1925 are symmetrically arranged with respect to the second direction, and the adjacent two third light-transmitting openings 1925 have opposite orientations in the second direction.

[0104] It can be understood that the first light-emitting unit 1621 corresponds to the first light-filtering unit 1931, the first light-dimming opening 1913, and the first light-transmitting opening 1923; the second light-emitting unit 1622 corresponds to the second light-filtering unit 1932, the second light-dimming opening 1914, and the second light-transmitting opening 1924; and the third light-emitting unit 1623 corresponds to the third light-filtering unit 1933, the third light-dimming opening 1915, and the third light-transmitting opening 1925.

[0105] As Figures 6 to 8 shown, it can be that the protruding direction of the first part 1926 of the m o th group of light-transmitting openings 1922 is different from that of the first part 1926 of the m e th group of light-transmitting openings 1922, or it can be that the protruding direction of the first part 1926 of the n o th group of light-transmitting openings 1922 is different from that of the first part 1926 of the n e th group of light-transmitting openings 1922; m and n are positive integers, m o and n o are odd numbers, m e and n e are even numbers, and the first direction is perpendicular to the second direction.

[0106] As Figure 6 and Figure 7 shown, in the m o th group of light-transmitting openings 1922, the first part 1926 of the first light-transmitting opening 1923 protrudes positively in the second direction with respect to the second part 1927, the first part 1926 of the second light-transmitting opening 1924 protrudes positively in the second direction with respect to the second part 1927, and the first part 1926 of the third light-transmitting opening 1925 protrudes positively in the second direction with respect to the second part 1927; in the m eAmong the groups of light-transmitting openings 1922, the first part 1926 of the first light-transmitting opening 1923 protrudes in the reverse direction along the second direction with respect to the second part 1927, the first part 1926 of the second light-transmitting opening 1924 protrudes in the reverse direction along the second direction with respect to the second part 1927, and the first part 1926 of the third light-transmitting opening 1925 protrudes in the reverse direction along the second direction with respect to the second part 1927.

[0107] wherein Figure 6 the first part 1926 is a triangular protrusion protruding with respect to the second part 1927; Figure 7 the first part 1926 is an arc-shaped protrusion protruding with respect to the second part 1927, and the width of the line connecting the two ends of the first part is equal to the width of the light-transmitting opening. The arc-shaped protrusions of the mth o group are equivalent to stretching the light-transmitting opening 1922 upward, and the arc-shaped protrusions of the mth e group are equivalent to stretching the light-transmitting opening 1922 downward.
