Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display terminal. Background Art

[0002] A color filter layer can be set on the light-emitting surface of the display panel. For example, in POL Less technology, the color filter layer can replace the polarizer (POL) to reduce the display panel's reflection of ambient light. The use of POL Less technology can reduce the cost and power consumption of the display panel. However, the color filter layer includes color resistors of multiple colors. Due to the difference in the color ratio of the color resistors, the display surface will have hue deviation when the screen is off. For example, the display surface cannot display black, and may have reddish, bluish, or greenish tints. Summary of the Invention

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0037] In order to achieve the above object, according to the first aspect of the present application, Figures 1 to 4 As shown, a display panel 1 is provided, comprising a substrate 10, a light-emitting layer 20 and a color filter layer 30; the light-emitting layer 20 is arranged on one side of the substrate 10, and the light-emitting layer 20 includes a plurality of light-emitting units 21; the color filter layer 30 is arranged on a side of the light-emitting layer 20 away from the substrate 10, and the color filter layer 30 includes a plurality of color resists 31, and the color resists 31 include a first filter portion 311 arranged in alignment with the light-emitting unit 21 and a second filter portion 312 arranged between two adjacent light-emitting units 21.

[0038] The display panel 1 may be an OLED panel, a Mini-LED panel, a Micro-LED panel, etc.

[0039] like Figure 1 As shown, the display panel 1 includes a display area AA and a non-display area NA located outside the display area AA. The display area AA is used to display images and includes multiple light-emitting units 21. The non-display area NA is provided with a driving circuit, such as a gate driving circuit, which is used to drive the light-emitting units 21 in the display area AA to emit light.

[0040] The substrate 10 may be a rigid substrate or a flexible substrate. The rigid substrate may be made of glass or the like. The flexible substrate may be made of polyimide, polycarbonate, polyethersulfone, polyethylene terephthalate, polyethylene naphthalate, polyarylate, or glass fiber reinforced plastic.

[0041] In some embodiments, the display panel 1 is an OLED panel. The light-emitting unit 21 includes an anode, a light-emitting material layer, and a cathode, which are stacked in sequence. The cathode is located on the side of the light-emitting material layer away from the substrate 10. The anode is used to provide holes, and the cathode is used to provide electrons. The holes and electrons recombine in the light-emitting material layer to emit light.

[0042] In some embodiments, the anode may be a metal or metal oxide material, such as indium tin oxide, indium zinc oxide, silver, or the like.

[0043] In some embodiments, the cathode may be an alloy of one or more of silver, aluminum, magnesium, etc.

[0044] In some embodiments, the display panel 1 may also be a QD-OLED (Quantum dot and Organic Light Emitting Diodes) panel. A QD-OLED display panel 1 may utilize a blue organic light emitting device as a light source to excite photochromic quantum dots to produce light emitting units 21 of different colors, thereby achieving full-color display.

[0045] An array layer may be further provided on the substrate 10, and the array layer is provided between the substrate 10 and the light emitting layer 20. The array layer is provided with a driving circuit, which is electrically connected to the anode and cathode of the light emitting unit 21 and is used to provide a driving signal for the light emitting unit 21.

[0046] In some embodiments, as Figure 3 and Figure 4 As shown, the color filter layer 30 is disposed on the light emitting layer 20. The color filter layer 30 can be used to replace the polarizer to reduce the reflection of the display panel 1 to the ambient light.

[0047] In some other embodiments, the color filter layer 30 may also be used to filter colored light to improve the color purity of the display panel 1 .

[0048] Alternatively, as Figures 2 to 4 As shown, the color filter layer 30 includes a light shielding portion 32. The light shielding portion 32 is located in the area between two adjacent color filters 31, and the color filters 31 are adjacent to the light shielding portion 32.

[0049] The light shielding portion 32 can block light to avoid color crosstalk between two adjacent light emitting units 21. The light shielding portion 32 can be made of a material with light absorption capability, such as a black matrix, black ink, etc.

[0050] In some embodiments, the light shielding portion 32 can also be a stack of at least two color resists 31 of different colors. Since a color resist 31 of one color only allows light of a corresponding wavelength to pass through, a stack of two color resists 31 of different colors can block light of any color from passing through, thereby achieving a light shielding effect. This arrangement can simplify the manufacturing process of the light shielding portion 32.

[0051] The color filter 31 allows light of a corresponding wavelength to pass through, while blocking light of other wavelengths. The color filter 31 includes a first filter portion 311 positioned in alignment with the light emitting unit 21 and a second filter portion 312 positioned between two adjacent light emitting units 21 .

[0052] The alignment of the first filter 311 with the light-emitting unit 21 means that the orthographic projection of the first filter 311 on the light-emitting layer 20 overlaps with the light-emitting unit 21, and light emitted by the light-emitting unit 21 can pass through the first filter 311. The first filter 311 is used to achieve color display of the display panel 1.

[0053] Specifically, the first filter portion 311 may include a red filter portion, a green filter portion, and a blue filter portion. The red filter portion allows red light to pass through, the green filter portion allows green light to pass through, and the blue filter portion allows blue light to pass through.

[0054] Optionally, in some embodiments, the geometric center of the first filter portion 311 coincides with the geometric center of the light emitting unit 21. It should be noted that due to process errors, the geometric center of the first filter portion 311 may deviate from the geometric center of the light emitting unit 21 within the range allowed by the process errors.

[0055] Optionally, the shape of the first filter portion 311 may be the same as the shape of the corresponding light emitting unit 21 .

[0056] The second filter portion 312 is disposed between two adjacent light-emitting units 21. In other words, the second filter portion 312 is not aligned with the light-emitting units 21, and the orthographic projection of the second filter portion 312 on the light-emitting layer 20 is located between the two adjacent light-emitting units 21. The shape of the second filter portion 312 can be circular, square, rectangular, elliptical, etc., but is not limited thereto.

[0057] It should be noted that both the first filter portion 311 and the second filter portion 312 are color filters, and the color of the second filter portion 312 can be the same as or different from the color of the first filter portion 311 .

[0058] When the screen is off, the first filter 311 reflects ambient light. Different colored filters 311 reflect different colors of light. When the first filter 311 reflects too much light of a certain color, the display panel 1 will appear biased toward that color when the screen is off. For example, when the first filter 311 reflects too much red light, the display panel 1 will appear reddish. Similar results apply to blue or green.

[0059] Since the first filter section 311 needs to be aligned with the light-emitting unit 21, adjusting the first filter section 311 will affect the display effect of the display panel 1. Therefore, the present application sets a second filter section 312 in the color block 31. The second filter section 312 does not need to realize color display. The second filter section 312 can be used to adjust the hue of the display panel 1 when the screen is off. In other words, there is no light-emitting unit 21 aligned below the second filter section 312. Therefore, when the display panel 1 displays an image, the second filter section 312 will not emit light, and therefore will not affect the display of the display panel 1.

[0060] For example, when the display panel 1 is reddish in the off state, the second filter portion 312 may be a green filter portion, which may reflect green light. The superposition of green light and red light may adjust the display panel 1 from a reddish hue to one close to black.

[0061] When the display panel 1 is greenish in the off state, the second filter portion 312 may be a red filter portion. The second filter portion 312 may reflect red light. The superposition of red light and green light may adjust the hue of the display panel 1 from greenish to close to black.

[0062] When the display panel 1 has hue deviations of other colors in the off state, the color of the second filter portion 312 can be set accordingly to make the display panel 1 close to black in the off state.

[0063] Alternatively, as Figure 2 and Figure 3 As shown, the light-emitting unit 21 includes a first color unit 211, a second color unit 212 and a third color unit 213, and the first filter part 311 includes a first color color block 3111, a second color color block 3112 and a third color color block 3113; wherein, the first color color block 3111 is arranged in alignment with the first color unit 211, the second color color block 3112 is arranged in alignment with the second color unit 212, and the third color color block 3113 is arranged in alignment with the third color unit 213, and the second filter part 312 is arranged between two adjacent first filter parts 311 of different colors.

[0064] The light emitting unit 21 may include a first color unit 211, a second color unit 212, and a third color unit 213. The light emitting colors of the first color unit 211, the second color unit 212, and the third color unit 213 may be red, green, and blue, respectively.

[0065] Taking OLED as an example, the colors of the first color unit 211 , the second color unit 212 and the third color unit 213 may be determined by the light emitting material layer, and different light emitting material layers may emit light of different colors.

[0066] Since the first filter 311 is aligned with the light emitting unit 21, in order to prevent the first filter 311 from affecting the light emitted by the light emitting unit 21, the first filter 311 is configured to allow light emitted by the first color unit 211 to pass through. In other words, the color of the first filter 311 needs to correspond to the color of the light emitted by the first color unit 211.

[0067] The first color unit 211 emits the same color as the first color resist 3111 , the second color unit 212 emits the same color as the second color resist 3112 , and the third color unit 213 emits the same color as the third color resist 3113 .

[0068] Specifically, the first filter portion 311 includes a first color resist 3111, a second color resist 3112, and a third color resist 3113. The color of the first color resist 3111 corresponds to the color of the first color unit 211, the color of the second color resist 3112 corresponds to the color of the second color unit 212, and the color of the third color resist 3113 corresponds to the color of the third color unit 213. For example, when the first color unit 211 is a red light-emitting unit, the second color unit 212 is a green light-emitting unit, and the third color unit 213 is a blue light-emitting unit, the first color resist 3111 is a red light filter, the second color resist 3112 is a green filter, and the third color resist 3113 is a blue filter.

[0069] like Figure 2 and Figure 3 As shown, in order to prevent the second filter 312 from affecting the color display of the display panel 1, the second filter 312 can be arranged between two adjacent first filters 311 of different colors. Since light of a color different from that of the second filter 312 cannot pass through the second filter 312, this can prevent light from two adjacent light-emitting units 21 from passing through the second filter 312 when the display panel 1 is displaying and affecting the display effect.

[0070] Alternatively, as Figure 2As shown, the minimum spacing between the first filter portion 311 and the second filter portion 312, which are adjacent to the second filter portion 312 and have different colors, is a first spacing s1. The minimum spacing between the first filter portion 311 and the second filter portion 312, which are adjacent to the second filter portion 312 and have the same color, is a second spacing s2. The first spacing s1 is smaller than the second spacing s2.

[0071] Specifically, if Figure 2 As shown, the color of the second filter portion 312 is the same as the color of the second color filter 3112, and the minimum distance between the color of the second filter portion 312 and the second color filter 3112 is a second distance s2. The color of the second filter portion 312 is different from both the first color filter 3111 and the third color filter 3113. The smaller of the distance between the color of the second filter portion 312 and the first color filter 3111 or the distance between the second filter portion 312 and the third color filter 3113 is a first distance s1. The first distance s1 is smaller than the second distance s2, meaning that the second filter portion 312 is positioned close to the first color filter 3111 and the third color filter 3113, while being positioned away from the second color filter 3112. This prevents light from the light-emitting unit 21 aligned with the second color filter 3112 from being emitted from the second filter portion 312.

[0072] Through the above arrangement, the second filter portion 312 can be arranged close to the first filter portion 311 of a different color from itself, so that the second filter portion 312 can be as far away as possible from the first filter portion 311 of the same color as itself.

[0073] Alternatively, as Figure 2 As shown, the lines connecting the geometric centers of two first filter sections 311 and the second filter section 312 of different colors adjacent to the second filter section 312 are not collinear. The lines connecting the geometric centers of two first filter sections 311 and the second filter section 312 of the same color adjacent to the second filter section 312 are not collinear. This arrangement increases the spacing between the second filter section 312 and any of the surrounding first filter sections 311.

[0074] Alternatively, as Figure 3 As shown, the second filter portion 312 includes a first sub-portion 3121, the color of the first sub-portion 3121 is the same as at least one of the first color color resist 3111, the second color color resist 3112 and the third color color resist 3113, the total area of ​​the first sub-portion 3121 is a first area, the total area of ​​the first filter portion 311 with the same color as the first sub-portion 3121 is a second area, and the ratio of the first area to the second area is 0.1 to 0.5.

[0075] The color of the first sub-section 3121 can be the same as at least one of the first color resist 3111, the second color resist 3112, and the third color resist 3113. That is, each first sub-section 3121 has the same color, and the color of each first sub-section 3121 is one of the first color resist 3111, the second color resist 3112, and the third color resist 3113. Alternatively, the first sub-section 3121 can be two different colors, and both colors of the first sub-section 3121 are any two of the first color resist 3111, the second color resist 3112, and the third color resist 3113. Alternatively, the first sub-section 3121 can be three different colors, and the three colors of the first sub-section 3121 are the same as the three colors of the first color resist 3111, the second color resist 3112, and the third color resist 3113.

[0076] With the above configuration, the second filter portion 312 can be made of at least one of the first color resist 3111 , the second color resist 3112 , and the third color resist 3113 , thereby simplifying the manufacturing process of the material of the second filter portion 312 .

[0077] The ratio of the first area to the second area is 0.1 to 0.5. When the first area is too small, the hue cannot be adjusted; when the first area is too large, it will lead to over-adjustment and hue deviation of other colors.

[0078] Alternatively, as Figure 4 As shown, Figure 4 Examples and Figure 3 The difference of the embodiment is the second filter 312. Figure 4 The second filter portion 312 includes a second sub-portion 3122, the second sub-portion 3122 includes a colored color block 31, and the color of the second sub-portion 3122 is different from any of the first color block 3111, the second color block 3112, and the third color block 3113. The total area of ​​the second sub-portion 3122 is the third area, and the total area of ​​the first filter portion 311 having the same color as the second sub-portion 3122 is the fourth area. The ratio of the third area to the fourth area is 0.1 to 0.5.

[0079] The difference between the second subsection 3122 and the first subsection 3121 is the color. The color of the second subsection 3122 is different from any of the first color color resist 3111, the second color color resist 3112 and the third color color resist 3113. For example, the color of the second subsection 3122 can be other colors other than the three primary colors such as yellow and cyan. Among them, the three primary colors refer to red, green and blue. By setting the color of the second subsection 3122 to be different from any of the three primary colors, targeted adjustments can be made according to the color cast of the display panel 1 in the off-screen state. At this time, the display panel 1 can be close to black in the off-screen state by only using the second subsection 3122 of one color. Through the above setting, the process of the second subsection 3122 can be simplified.

[0080] The ratio of the third area to the fourth area is 0.1 to 0.5. If the third area is too small, the hue adjustment will not be effective; if the third area is too large, it will lead to over-adjustment and hue deviation of other colors.

[0081] Alternatively, as Figure 1 、 Figure 2 and Figure 5 As shown, the display panel 1 includes a display area AA, the display area AA includes a first sub-area AA1 and a second sub-area AA2 arranged outside the first sub-area AA1, the color resist 31 includes a third filter portion 313 arranged between two adjacent light-emitting units 21, the third filter portion 313 is arranged in the first sub-area AA1, the second filter portion 312 is arranged in the second sub-area AA2, and the third filter portion 313 is a transparent material.

[0082] The light-emitting units 21 of the display area AA can be arranged in an array. That is, both the first sub-area AA1 and the second sub-area AA2 are provided with light-emitting units 21. The light-emitting units 21 of the first sub-area AA1 and the light-emitting units 21 of the second sub-area AA2 can be arranged in the same arrangement, thereby achieving consistent display effects in the first sub-area AA1 and the second sub-area AA2.

[0083] like Figure 1 As shown, the first sub-area AA1 can be a light-transmitting aperture area, which corresponds to an optical sensor, etc. The optical sensor is disposed on the non-light-emitting side of the display panel 1 and receives light incident from the outside into the first sub-area AA1, thereby realizing the sensing function of the optical sensor. The optical sensor includes a camera, etc.

[0084] like Figure 1 、 Figure 5 and Figure 6As shown, to ensure that the transmittance of the first sub-area AA1 meets the photosensitivity requirements of the optical sensor, multiple third filters 313 can be provided on the light shielding portion 32 of the first sub-area AA1. The material of the third filters 313 is transparent. Because the transmittance of transparent materials is greater than that of the light shielding portion 32, the provision of the third filters 313 can increase the transmittance of the first sub-area AA1.

[0085] The third filter portion 313 may be made of an organic material or an inorganic material and may be formed by filling the opening of the light shielding portion 32 with an insulating layer located above the color filter layer 30. By using a transparent insulating layer to form the third filter portion 313, the manufacturing process of the third filter portion 313 can be simplified.

[0086] After the third filter portion 313 is provided in the first sub-area AA1, ambient light can be incident on the light-emitting layer 20 of the display panel 1 through the third filter portion 313 and reflected by the cathode of the light-emitting layer 20, causing the reflectivity of the display panel 1 to increase. When the second filter portion 312 is not provided in the second sub-area AA2, the transmittance of the first sub-area AA1 will be greater than the transmittance of the second sub-area AA2. Because the transmittance of the second sub-area AA2 is lower than that of the first sub-area AA1, less light in the second sub-area AA2 can be incident on the cathode of the light-emitting layer 20, and less light can be reflected by the cathode. Therefore, in the off-screen state, the intensity of the light reflected by the second sub-area AA2 is lower than the intensity of the light reflected by the first sub-area AA1. This results in inconsistent intensities of light reflected by the first sub-area AA1 and the second sub-area AA2 in the off-screen state, i.e., the first sub-area AA1 and the second sub-area AA2 are visually distinct, i.e., the first sub-area AA1 is easily observed, affecting the integrated black effect of the display area AA in the off-screen state.

[0087] In this application, if Figure 2 As shown, since the second sub-area AA2 is provided with a second filter 312, the second filter 312 allows the same-color light in the ambient light to pass through. The transmitted light is then reflected by the cathode of the light-emitting layer 20. Therefore, the second filter 312 can also increase the intensity of the light reflected from the second sub-area AA2 to a certain extent. This arrangement not only improves the hue deviation problem of the display panel 1 in the off state, but also reduces the difference in the intensity of the light reflected from the first sub-area AA1 and the second sub-area AA2. This improves the visibility of the first sub-area AA1 in the off state and enhances the integrated black effect of the display area AA in the off state.

[0088] Optionally, in some embodiments, the second sub-area AA2 may also be provided with a third filter portion 313 , thereby further reducing the difference in refractive index between the first sub-area AA1 and the second sub-area AA2 .

[0089] The number of the first sub-areas AA1 can be set as needed, and the number of the first sub-area AA1 is at least one.

[0090] Optionally, the area of ​​a third filter portion 313 is greater than or equal to the area of ​​a second filter portion 312. Through the above configuration, the transmittance of the first sub-area AA1 can be further improved to meet the photosensitivity requirements of the optical sensor.

[0091] Optionally, the color of the first color resist 3111 is red, the color of the second color resist 3112 is green, and the color of the third color resist 3113 is blue; wherein, the area of ​​a third color resist 3113 is larger than the area of ​​a first color resist 3111, and the area of ​​a first color resist 3111 is larger than the area of ​​a second color resist 3112.

[0092] Because the lifespans of the luminescent material layers of the light-emitting cells 21 of different colors are different, the areas of the light-emitting cells 21 of different colors are different to match the lifespans of the light-emitting cells 21 of different colors. For example, the area of ​​the blue light-emitting cell 21 can be larger than the area of ​​the red light-emitting cell 21, and the area of ​​the red light-emitting cell 21 can be larger than the area of ​​the green light-emitting cell 21. That is, the first color cell 211 is a red light-emitting cell 21, the second color cell 212 is a green light-emitting cell 21, and the third color cell 213 is a blue light-emitting cell 21.

[0093] Accordingly, if Figure 2 As shown, the area of ​​the first filter 311 aligned with each color of the light-emitting unit 21 is also different. The area of ​​a third color filter 3113 is larger than the area of ​​a first color filter 3111, and the area of ​​a first color filter 3111 is larger than the area of ​​a second color filter 3112, thereby matching the size of the first filter 311 with the size of the light-emitting unit 21. In other words, when the area of ​​the light-emitting unit 21 is larger, the area of ​​the first filter 311 aligned with the light-emitting unit 21 is also larger; when the area of ​​the light-emitting unit 21 is smaller, the area of ​​the first filter 311 aligned with the light-emitting unit 21 is also smaller.

[0094] It should be understood that since the area of ​​the light-emitting unit 21 is affected by factors such as the material lifespan of the light-emitting material layer, and the area of ​​the first filter portion 311 is limited by the area of ​​the light-emitting unit 21, the area of ​​the first filter portion 311 cannot be adjusted at will. Therefore, the hue deviation problem of the display panel 1 in the off-screen state cannot be improved by adjusting the area of ​​the first filter portion 311. However, the second filter portion 312 does not participate in the display of light, so its color and area are adjustable. By adjusting the color and area of ​​the second filter portion 312, the area ratio of the color filter in the color filter layer 30 of the display panel 1 can be made close to the area ratio required to render black in the off-screen state, thereby improving the hue deviation problem in the off-screen state.

[0095] Alternatively, as Figure 3 、 Figure 4 and Figure 6 As shown, the display panel 1 includes a touch layer 40, which is arranged between the light-emitting layer 20 and the color filter layer 30. The touch layer 40 includes a plurality of touch electrodes 41. The touch layer 40 includes a plurality of touch electrodes 41, and the orthographic projection of the touch electrode 41 on the color filter layer 30 is located between two adjacent color resists 31.

[0096] The touch layer 40 is used to implement the touch function of the display panel 1. The touch layer 40 can be a self-capacitive touch layer or a mutual-capacitive touch layer.

[0097] In some embodiments, the touch layer 40 includes a first metal layer and a second metal layer, a first insulating layer is disposed between the first metal layer and the second metal layer, and a second insulating layer is disposed between the second metal layer and the color filter layer 30. The first insulating layer and the second insulating layer can be made of an inorganic insulating material, such as silicon oxide, silicon nitride, or silicon oxynitride.

[0098] The touch electrodes 41 can be arranged on the first metal layer, and two adjacent touch electrodes 41 can be bridged by wiring on the second metal layer. The first metal layer and the second metal layer can be metal grid lines. The touch electrodes 41 with a metal grid structure have low resistance and high sensitivity.

[0099] like Figure 3 As shown, since the color resist 31 allows light of the same color to pass through, to prevent ambient light from passing through the color resist 31 and entering the touch electrode 41, causing light reflection from the touch electrode 41, the touch electrode 41 can be positioned between two adjacent color resists 31, that is, the touch electrode 41 and the color resist 31 are not aligned. For example, the touch electrode 41 can be positioned below the light shielding portion 32. This means that the orthographic projection of the touch electrode 41 on the color filter layer 30 is located within the light shielding portion 32.

[0100] It should be noted that, due to the provision of the second filter portion 312 and / or the third filter portion 313, a portion of the original light shielding portion 32 is occupied, resulting in a reduction in the wiring space of the metal grid lines of the touch electrode 41. Figure 2 As shown, four first filter portions 311 are arranged around a second filter portion 312, and the metal grid line can be arranged between two color blocks 31 with a larger spacing between two adjacent color blocks 31, that is, the metal grid line is not arranged between the line segments corresponding to the first spacing s1 and the second spacing s2 in the figure, thereby increasing the layout space of the metal grid line.

[0101] Optionally, the extendable trajectory of the metal grid lines can be adjusted according to the outline of the adjacent color resist 31, and the metal grid lines are arranged on the periphery of the color resist 31. For example, when the color resist 31 is circular, the shape of the metal grid lines near the outline of the color resist 31 can also be circular, thereby making the metal grid lines easier to route and layout, that is, easier to connect with adjacent metal grid lines.

[0102] According to the second aspect of this application, Figure 7 As shown, a display terminal 2 is provided, and the display terminal 2 includes the above-mentioned display panel 1.

[0103] In this embodiment, if Figure 7 As shown, the display terminal 2 includes a display panel 1 and a terminal body 3, and the display panel 1 and the terminal body 3 are combined into one body.

[0104] In this embodiment, the display terminal 2 can be any product or component with a display function, such as a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, or a navigator.
