Description

Display panel and display device Technical Field

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

[0002] Organic Light Emitting Diode (OLED) displays offer advantages such as wide viewing angles, high contrast, and fast response times. However, OLED displays suffer from insufficient black levels when the screen is off, which affects the visual quality.

[0003] Therefore, a technical solution is needed to improve the technical problem of insufficient blackness of an organic light emitting diode display device when the screen is off. SUMMARY OF THE INVENTION

[0004] The present application provides a display panel and a display device to improve the problem of insufficient blackness of the display panel and the display device when the screen is off.

[0005] In a first aspect, the present application provides a display panel, which includes a substrate layer, a light-emitting device layer, and a color filter layer. The light-emitting device layer is arranged on the substrate layer. The light-emitting device layer includes a red light-emitting unit, a green light-emitting unit, and a blue light-emitting unit arranged at intervals. The green light emission spectrum of the green light-emitting unit has a green light peak wavelength, which is greater than or equal to 495 nanometers and less than or equal to 530 nanometers. The color filter layer is arranged on the light-emitting side of the light-emitting device layer. The color filter layer includes a red color resist covering the red light-emitting unit, a green color resist covering the green light-emitting unit, and a blue color resist covering the blue light-emitting unit. The transmission spectrum of the green color resist has a wavelength of maximum green light transmittance, which is greater than or equal to 495 nanometers and less than or equal to 530 nanometers.

[0006] In a second aspect, the present application further provides a display device, which includes the display panel of any of the above embodiments. Beneficial effects

[0007] In the display panel and display device of some embodiments of the present application, the wavelength of maximum green light transmittance of the green color resist is greater than or equal to 495 nanometers and less than or equal to 530 nanometers. In this way, the wavelength of maximum green light transmittance of the green color resist moves toward a shorter wavelength, that is, the wavelength of maximum green light transmittance of the green color resist is blue-shifted. The distance between 555 nanometers and the wavelength of maximum green light transmittance is large, and the transmittance of the green color resist to light of 555 nanometers decreases while the absorptivity increases. Accordingly, the reflectivity of the green color resist to light of 555 nanometers is low, thereby reducing the reflectivity of the display panel to light of 555 nanometers when the screen is off. Less 555 nanometer light is reflected into the human eye, which can improve the problem of low blackness when the display panel is off. At the same time, the peak wavelength of green light is greater than or equal to 495 nanometers and less than or equal to 530 nanometers, so that the peak wavelength of green light and the wavelength of maximum green light transmittance are blue-shifted together, which can reduce the distance between the wavelength of maximum green light transmittance and the wavelength of peak green light. The wavelength of green light with the highest transmittance corresponds to a higher relative intensity of green light, thereby increasing the brightness of the green light displayed by the display panel. High brightness helps reduce the overall power consumption of the display panel. Therefore, the display panel and display device of the embodiments of the present application can have low power consumption and improve the problem of insufficient blackness when the screen is off.

[0017] 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 making creative efforts are within the scope of protection of this application.

[0018] 1 , which is a schematic cross-sectional view of a display panel according to some embodiments of the present application, shows that the display panel 100 includes a substrate layer 11 , a light emitting device layer 21 , and a filter layer 31 .

[0019] The base layer 11 serves as a support. The base layer 11 may be a glass base or a flexible base. In a specific embodiment, the base layer 11 may be a flexible base to allow the display panel 100 to be flexible. Flexible bases include, but are not limited to, polyimide layers.

[0020] The filter layer 31 is not only used to reduce the reflectivity of ambient light and thus improve display contrast, but also can reduce the thickness of the display panel 100 to ensure that the display panel 100 can achieve flexible display. The filter layer 31 is provided on the light-emitting side of the light-emitting device layer 21.

[0021] Specifically, the filter layer 31 is disposed on the side of the light-emitting device layer 21 facing away from the base layer 11. The filter layer 31 includes a black matrix 33, which includes a plurality of openings 331 extending through the thickness of the black matrix 33. The filter layer 31 also includes a color filter layer 32. The color filter layer 32 includes a red color resist 321, a green color resist 322, and a blue color resist 323. The red color resist 321, the green color resist 322, and the blue color resist 323 are respectively disposed in the plurality of openings 331.

[0022] Please refer to FIG. 2 , which shows emission spectra of a red light emitting unit, a green light emitting unit, and a blue light emitting unit and transmission spectra of red color resist, green color resist, and blue color resist in some embodiments of the present application.

[0023] The transmission spectrum CFG of the green color resist 322 has a wavelength of maximum green light transmittance, which corresponds to the abscissa of point GF on the transmission spectrum CFG of the green color resist 322. At the wavelength of maximum green light transmittance, the transmission spectrum CFG of the green color resist 322 has maximum transmittance. The maximum transmittance of the transmission spectrum CFG of the green color resist 322 corresponds to the ordinate of point GF on the transmission spectrum CFG.

[0024] The red color filter 321 has a wavelength of maximum red light transmittance, which corresponds to the abscissa of point RF on the CFR transmission spectrum of the red color filter 321. At the wavelength of maximum red light transmittance, the CFR transmission spectrum of the red color filter 321 has maximum transmittance. The maximum transmittance of the CFR transmission spectrum of the red color filter 321 corresponds to the ordinate of point RF on the CFR transmission spectrum.

[0025] The transmission spectrum CFB of the blue color resist 323 has a wavelength of maximum blue light transmittance, which corresponds to the abscissa of point BF on the transmission spectrum CFB of the blue color resist 323. At the wavelength of maximum blue light transmittance, the transmission spectrum CFB of the blue color resist 323 has maximum transmittance. The maximum transmittance of the transmission spectrum CFB of the blue color resist 323 corresponds to the ordinate of point BF on the transmission spectrum CFB.

[0026] The light-emitting device layer 21 is configured to emit light. The light-emitting device layer 21 includes a plurality of light-emitting units 22. These light-emitting units 22 include a red light-emitting unit 23, a green light-emitting unit 24, and a blue light-emitting unit 25. The light-emitting units 22 can be any one selected from organic light-emitting diodes, micro-LEDs, sub-millimeter light-emitting diodes (mini-LEDs), and quantum dot light-emitting diodes.

[0027] For the purpose of describing the technical solution of the present application, the plurality of light-emitting units 22 are all organic light-emitting diodes, but are not limited thereto. The red light-emitting unit 23 includes a red organic light-emitting layer 231, a first anode 232, and a common cathode 26. The red organic light-emitting layer 231 is disposed between the first anode 232 and the common cathode 26. The green light-emitting unit 24 includes a green organic light-emitting layer 241, a second anode 242, and a common cathode 26. The green organic light-emitting layer 241 is disposed between the second anode 242 and the common cathode 26. The blue light-emitting unit 25 includes a blue organic light-emitting layer 251, a third anode 252, and a common cathode 26. The blue organic light-emitting layer 251 is disposed between the third anode 252 and the common cathode 26. Therefore, the red light-emitting unit 23, the green light-emitting unit 24, and the blue light-emitting unit 25 share a common cathode 26.

[0028] As shown in FIG1 , the red color resist 321 covers the red light emitting unit 23, and the orthographic projection of the red color resist 321 on the substrate layer 11 overlaps with the orthographic projection of the red light emitting unit 23 on the substrate layer 11. Specifically, the orthographic projection of the red organic light emitting layer 231 on the substrate layer 11 is located within the orthographic projection of the red color resist 321 on the substrate layer 11.

[0029] As shown in FIG2 , the red light emission spectrum ELR of the red light emitting unit 23 has a red light peak wavelength, which corresponds to the abscissa of point RL on the red light emission spectrum ELR of the red light emitting unit 23. At the red light peak wavelength, the red light emission spectrum ELR of the red light emitting unit 23 has a maximum light intensity. The maximum light intensity of the red light emission spectrum ELR of the red light emitting unit 23 corresponds to the ordinate of point RL on the red light emission spectrum ELR.

[0030] As shown in FIG1 , the green color resist 322 covers the green light emitting unit 24, and the orthographic projection of the green color resist 322 on the substrate layer 11 overlaps with the orthographic projection of the green light emitting unit 24 on the substrate layer 11. Specifically, the orthographic projection of the green organic light emitting layer 241 on the substrate layer 11 is located within the orthographic projection of the green color resist 322 on the substrate layer 11.

[0031] As shown in FIG2 , the green light emission spectrum ELG of the green light emitting unit 24 has a green peak wavelength, which corresponds to the abscissa of point GL on the green light emission spectrum ELG of the green light emitting unit 24. At the green peak wavelength, the green light emission spectrum ELG of the green light emitting unit 24 has a maximum light intensity. The maximum light intensity of the green light emission spectrum ELG of the green light emitting unit 24 corresponds to the ordinate of point GL on the green light emission spectrum ELG.

[0032] As shown in FIG1 , the blue color resist 323 covers the blue light emitting unit 25, and the orthographic projection of the blue color resist 323 on the substrate layer 11 overlaps with the orthographic projection of the blue light emitting unit 25 on the substrate layer 11. Specifically, the orthographic projection of the blue organic light emitting layer 251 on the substrate layer 11 is located within the orthographic projection of the blue color resist 323 on the substrate layer 11.

[0033] As shown in FIG2 , the blue light emission spectrum ELB of the blue light emitting unit 25 has a blue light peak wavelength, which corresponds to the abscissa of point BL on the blue light emission spectrum ELB of the blue light emitting unit 25. At the blue light peak wavelength, the blue light emission spectrum ELB of the blue light emitting unit 25 has a maximum light intensity. The maximum light intensity of the blue light emission spectrum ELB of the blue light emitting unit 25 corresponds to the ordinate of point BL on the blue light emission spectrum ELB.

[0034] In related technologies, to improve the light extraction efficiency of display panels, the low-transmittance polarizer is replaced with a high-transmittance color filter layer. However, removing the polarizer results in a higher reflectivity of the display panel to ambient light, resulting in a low black level when the display is off, reducing the visual quality of the display panel when the screen is off.

[0035] To address the issues in the related art, the present application reduces the transmittance of the color filter layer 32 at 555 nm light, thereby increasing its absorptivity at 555 nm light, given that the human eye is more sensitive to light at 555 nm. This reduces the reflectivity of the color filter layer 32 of the display panel 100 when the screen is off, reducing the amount of 555 nm light reflected from the display panel 100 when the screen is off. This improves the problem of low black levels when the display panel 100 is off.

[0036] Analysis shows that within the wavelength band corresponding to green light, increasing the distance between 555 nanometers and the wavelength of maximum green light transmittance—for example, shifting the wavelength of maximum green light transmittance toward shorter wavelengths (blue shifting)—can reduce the transmittance of the green color resist 322 at 555 nanometers, thereby increasing its light absorption rate at 555 nanometers. Consequently, the green color resist 322 has a lower reflectivity at 555 nanometers, reducing the reflectivity of the color filter layer 32 of the display panel 100 at 555 nanometers and improving the issue of insufficient black levels when the display panel 100 is off. Furthermore, to ensure a high intensity of the green light wavelength with the highest transmittance through the green color resist 322, the distance between the green peak wavelength and the wavelength of maximum green transmittance needs to be small. To reduce the distance between the green peak wavelength and the wavelength of maximum green transmittance, the distance between 555 nanometers and the green peak wavelength can also be increased. The green light peak wavelength can also be shifted toward shorter wavelengths (blue shift) to increase the distance between 555 nanometers and the green light peak wavelength.

[0037] Specifically, in this application, as shown in Figure 2, the wavelength of maximum green light transmittance (corresponding to the horizontal coordinate of point GF) is greater than or equal to 495 nanometers and less than or equal to 530 nanometers, and the peak green light wavelength (corresponding to the horizontal coordinate of point GL) is greater than or equal to 495 nanometers and less than or equal to 530 nanometers. This shifts the wavelength of maximum green light transmittance of the green color resist toward shorter wavelengths, i.e., the wavelength of maximum green light transmittance of the green color resist is blue-shifted, compared to the related art where the wavelength of maximum green light transmittance is greater than 530 nanometers (e.g., any wavelength between 532 nanometers and 540 nanometers). The larger the gap between 555 nanometers and the wavelength of maximum green light transmittance, the green color resist's transmittance at 555 nanometers decreases while its absorptivity increases. Consequently, the green color resist has a lower reflectivity at 555 nanometers, thereby reducing the reflectivity of 555 nanometers when the display panel is off. This reduces the amount of 555 nanometer light reflected into the human eye, which can improve the problem of low black levels when the display panel is off.

[0038] At the same time, compared to the related art where the green light peak wavelength is greater than 530 nanometers (e.g., any wavelength between 532 nanometers and 540 nanometers), the green light peak wavelength is greater than or equal to 495 nanometers and less than or equal to 530 nanometers. This shifts the green light peak wavelength and the wavelength of maximum green light transmittance together to the blue, narrowing the gap between the wavelength of maximum green light transmittance and the green light peak wavelength. The wavelength of maximum green light transmittance with the highest transmittance corresponds to a higher intensity of green light, thereby increasing the brightness of the green light displayed by the display panel. This high brightness helps reduce the overall power consumption of the display panel.

[0039] Therefore, the maximum transmittance wavelength of green light is greater than or equal to 495 nanometers and less than or equal to 530 nanometers, and the peak wavelength of green light is greater than or equal to 495 nanometers and less than or equal to 530 nanometers, so that the display panel of the embodiment of the present application can have low power consumption and can improve the problem of insufficient blackness when the screen is off.

[0040] Optionally, the green light peak wavelength is greater than or equal to 500 nanometers and less than or equal to 525 nanometers. Optionally, the green light peak wavelength is greater than or equal to 505 nanometers and less than or equal to 520 nanometers. Optionally, the green light peak wavelength is greater than or equal to 508 nanometers and less than or equal to 515 nanometers. For example, the green light peak wavelength can be 495 nanometers, 498 nanometers, 500 nanometers, 502 nanometers, 505 nanometers, 508 nanometers, 510 nanometers, 512 nanometers, 515 nanometers, 518 nanometers, 520 nanometers, 522 nanometers, 525 nanometers, 528 nanometers, or 530 nanometers.

[0041] Optionally, the wavelength of maximum green light transmittance is greater than or equal to 498 nanometers and less than or equal to 525 nanometers. Optionally, the wavelength of maximum green light transmittance is greater than or equal to 502 nanometers and less than or equal to 523 nanometers. Optionally, the wavelength of maximum green light transmittance is greater than or equal to 505 nanometers and less than or equal to 518 nanometers. Optionally, the wavelength of maximum green light transmittance is greater than or equal to 508 nanometers and less than or equal to 515 nanometers. For example, the wavelength of maximum green light transmittance can be 495 nanometers, 498 nanometers, 500 nanometers, 502 nanometers, 505 nanometers, 508 nanometers, 510 nanometers, 512 nanometers, 515 nanometers, 518 nanometers, 520 nanometers, 525 nanometers, 528 nanometers, or 530 nanometers.

[0042] In some embodiments, the absolute value of the difference between the green light peak wavelength and the green light maximum transmittance wavelength is greater than or equal to 0 nanometers and less than or equal to 15 nanometers. With this arrangement, the distance between the green light peak wavelength and the green light maximum transmittance wavelength is smaller, so that the light intensity of the green light corresponding to the green light maximum transmittance wavelength is greater. The green light corresponding to the green light maximum transmittance wavelength not only has the maximum transmittance through the green color resist 322, but also has a higher brightness, further reducing the power consumption of the green light corresponding to the green light maximum transmittance wavelength. Optionally, the absolute value of the difference between the green light peak wavelength and the green light maximum transmittance wavelength is greater than or equal to 2 nanometers and less than or equal to 12 nanometers.

[0043] Optionally, the absolute value of the difference between the green light peak wavelength and the wavelength of maximum green light transmittance is greater than or equal to 2 nanometers and less than or equal to 10 nanometers. Optionally, the absolute value of the difference between the green light peak wavelength and the wavelength of maximum green light transmittance is greater than or equal to 3 nanometers and less than or equal to 8 nanometers. Optionally, the absolute value of the difference between the green light peak wavelength and the wavelength of maximum green light transmittance is greater than or equal to 1 nanometer and less than or equal to 6 nanometers. Optionally, the absolute value of the difference between the green light peak wavelength and the wavelength of maximum green light transmittance is greater than or equal to 2 nanometers and less than or equal to 5 nanometers.

[0044] In some embodiments, the green light peak wavelength is greater than or equal to the green light maximum transmittance wavelength. This configuration ensures that the light corresponding to the green light maximum transmittance wavelength has a higher light intensity while also reducing the distance that the green light peak wavelength shifts toward shorter wavelengths, thereby reducing the manufacturing difficulty of the green organic light emitting layer 241.

[0045] In some embodiments, the difference between the human eye sensitivity wavelength and the wavelength of maximum green light transmittance is greater than or equal to 20 nanometers, the difference between the human eye sensitivity wavelength and the wavelength of maximum green light transmittance is greater than or equal to 20 nanometers, and the human eye sensitivity wavelength is greater than or equal to 550 nanometers and less than or equal to 560 nanometers. This configuration increases the distance between the human eye sensitivity wavelength and the wavelength of maximum green light transmittance, reducing the transmittance of the green color resist 322 for light at the human eye sensitivity wavelength and increasing its absorptivity, thereby lowering the reflectivity of the green color resist 322 for light at the human eye sensitivity wavelength. The reflectivity of the display panel 100 for light at the human eye sensitivity wavelength is also reduced when the display panel 100 is off. If the human eye is more sensitive to light at the human eye sensitivity wavelength, the reflectivity of the display panel 100 for light at the human eye sensitivity wavelength is reduced, resulting in less light at the human eye sensitivity wavelength reflected into the human eye when the display panel 100 is off. Less light at the human eye sensitivity wavelength reflected into the human eye can improve the problem of low black levels when the display panel 100 is off.

[0046] At the same time, this configuration also increases the distance between the green light peak wavelength and the wavelength sensitive to the human eye, thereby reducing the distance between the wavelength of maximum green light transmittance and the green light peak wavelength. The green light peak wavelength and the wavelength of maximum green light transmittance are simultaneously blue-shifted, ensuring the intensity of the green light corresponding to the wavelength of maximum green light transmittance, thereby increasing the brightness of the green light displayed by the display panel 100. High-brightness green light helps reduce the power consumption required by the display panel to emit green light, thereby reducing the overall power consumption of the display panel 100.

[0047] Therefore, the difference between the wavelength to which the human eye is sensitive and the wavelength of maximum green light transmittance is greater than or equal to 20 nanometers, and the difference between the wavelength to which the human eye is sensitive and the wavelength of green light peak is greater than or equal to 20 nanometers. This can enable the display panel 100 of some embodiments provided in the present application to have low power consumption and improve the problem of insufficient blackness when the screen is off.

[0048] Further analysis reveals that the distance between the minimum wavelength of red light and 555 nanometers is smaller than the distance between the maximum wavelength of blue light and 555 nanometers. Therefore, in this application, the distance between the wavelength of maximum red light transmittance and the wavelength sensitive to the human eye is increased. Specifically, the wavelength of maximum red light transmittance is shifted toward a longer wavelength (redshifted) to reduce the transmittance of the red color resist 321 at wavelengths sensitive to the human eye, thereby increasing its absorptivity at these wavelengths. When the display panel 100 is in the off state, the red color resist 321 of the display panel 100 has a higher absorptivity and a lower reflectivity at wavelengths sensitive to the human eye. This further reduces the amount of light at wavelengths sensitive to the human eye that enters the human eye after reflection, further improving the issue of low black levels when the display panel 100 is off. Furthermore, to ensure the intensity of the wavelength of maximum red light transmittance, the distance between the wavelength of maximum red light transmittance and the peak red light wavelength needs to be smaller. The peak red light wavelength can also be shifted toward a longer wavelength to reduce the distance between the wavelength of maximum red light transmittance and the peak red light wavelength.

[0049] In some embodiments, the wavelength of maximum red light transmittance is greater than or equal to 625 nanometers and less than or equal to 650 nanometers, and the peak red light wavelength is greater than or equal to 625 nanometers and less than or equal to 640 nanometers. Thus, compared to the related art where the wavelength of maximum red light transmittance is less than 625 nanometers, the maximum red light transmittance of the present application shifts toward a longer wavelength (redshift), and the red color resist 321 has a lower transmittance of 555 nanometer light. Correspondingly, the red color resist 321 has a higher absorptivity of 555 nanometer light, which in turn results in a lower reflectivity of the red color resist 321 to 555 nanometer light. The color filter layer 32 of the display panel 100 with the screen off further reduces its reflectivity of 555 nanometer light, resulting in less 555 nanometer light being reflected by the display panel 100 into the human eye when the screen is off, thereby improving the problem of insufficient blackness of the display panel 100 when the screen is off.

[0050] At the same time, compared with the related art in which the red light peak wavelength is less than 625 nanometers (for example, any wavelength between 620 nanometers and 624 nanometers), the red light peak wavelength is greater than or equal to 625 nanometers and less than or equal to 640 nanometers, so that the red light peak wavelength is also red-shifted, and the distance between the red light peak wavelength and the wavelength of maximum red light transmittance is smaller, so as to increase the light intensity of the red light corresponding to the maximum red light transmittance wavelength, and increase the brightness of the red light corresponding to the maximum red light transmittance wavelength, which is beneficial to reduce the power consumption of the red light and further reduce the overall power consumption of the display panel.

[0051] Therefore, the maximum transmittance wavelength of red light is greater than or equal to 625 nanometers and less than or equal to 650 nanometers, and the peak wavelength of red light is greater than or equal to 625 nanometers and less than or equal to 640 nanometers. The maximum transmittance wavelength of red light and the peak wavelength of red light can be redshifted, further improving the problem of insufficient blackness of the display panel in the screen-off state, while also reducing the power consumption of the display panel.

[0052] Optionally, the wavelength of maximum red light transmittance is greater than or equal to 628 nanometers and less than or equal to 648 nanometers. Optionally, the wavelength of maximum red light transmittance is greater than or equal to 632 nanometers and less than or equal to 645 nanometers. Optionally, the wavelength of maximum red light transmittance is greater than or equal to 635 nanometers and less than or equal to 645 nanometers. For example, the wavelength of maximum red light transmittance can be 625 nanometers, 628 nanometers, 630 nanometers, 632 nanometers, 635 nanometers, 638 nanometers, 640 nanometers, 642 nanometers, 645 nanometers, 648 nanometers, or 650 nanometers.

[0053] Optionally, the red light peak wavelength is greater than or equal to 628 nanometers and less than or equal to 638 nanometers. Optionally, the red light peak wavelength is greater than or equal to 630 nanometers and less than or equal to 635 nanometers. For example, the red light peak wavelength can be 625 nanometers, 628 nanometers, 630 nanometers, 632 nanometers, 635 nanometers, 638 nanometers, or 640 nanometers.

[0054] In some embodiments, the absolute value of the difference between the wavelength of maximum red light transmittance and the peak wavelength of red light is greater than or equal to 0 nanometers and less than or equal to 15 nanometers. This arrangement reduces the distance between the peak wavelength of red light and the wavelength of maximum red light transmittance, resulting in a higher intensity of red light at the wavelength of maximum red light transmittance. The red light corresponding to the wavelength of maximum red light transmittance not only has maximum transmittance through the red color resist 321 but also has high brightness, which helps reduce power consumption of the red light corresponding to the wavelength of maximum red light transmittance. Optionally, the absolute value of the difference between the peak wavelength of red light and the wavelength of maximum red light transmittance is greater than or equal to 2 nanometers and less than or equal to 12 nanometers. Optionally, the absolute value of the difference between the peak wavelength of red light and the wavelength of maximum red light transmittance is greater than or equal to 4 nanometers and less than or equal to 10 nanometers. Optionally, the absolute value of the difference between the peak wavelength of red light and the wavelength of maximum red light transmittance is greater than or equal to 6 nanometers and less than or equal to 8 nanometers. Optionally, the absolute value of the difference between the peak wavelength of red light and the wavelength of maximum red light transmittance is greater than or equal to 1 nanometer and less than or equal to 12 nanometers. Optionally, an absolute value of a difference between a red light peak wavelength and a red light maximum transmittance wavelength is greater than or equal to 2 nanometers and less than or equal to 6 nanometers.

[0055] In some embodiments, the absolute value of the difference between the wavelength of maximum red light transmittance and the red peak wavelength can be greater than the absolute value of the difference between the green peak wavelength and the wavelength of maximum green light transmittance. This configuration can reduce the absolute value of the difference between the green peak wavelength and the wavelength of maximum green light transmittance, thereby increasing the brightness of the green light corresponding to the wavelength of maximum green light transmittance and further reducing the power consumption of the green light.

[0056] In other embodiments, the absolute value of the difference between the wavelength of maximum red light transmittance and the peak wavelength of red light can be smaller than the absolute value of the difference between the peak wavelength of green light and the wavelength of maximum green light transmittance. This arrangement can make the absolute value of the difference between the wavelength of maximum red light transmittance and the peak wavelength of red light smaller, which is more conducive to improving the brightness of the red light corresponding to the wavelength of maximum red light transmittance and further reducing the power consumption of red light. In some embodiments, the difference between the wavelength of maximum red light transmittance minus the wavelength sensitive to the human eye is greater than 80 nanometers, and the difference between the wavelength of peak red light minus the wavelength sensitive to the human eye is greater than 80 nanometers. In this arrangement, the distance between the wavelength of maximum red light transmittance and the wavelength sensitive to the human eye is larger, and the transmittance of the red color resist 321 to light of the wavelength sensitive to the human eye is reduced. Correspondingly, the red color resist 321 has a greater absorption rate for light of the wavelength sensitive to the human eye, thereby making the reflectivity of the red color resist 321 to light of the wavelength sensitive to the human eye lower. The reflectivity of the color filter layer 32 of the display panel 100 with the screen off to light of wavelengths sensitive to the human eye is further reduced, and less light of wavelengths sensitive to the human eye is reflected into the human eye by the display panel 100 with the screen off, thereby improving the problem of insufficient blackness of the display panel 100 when the screen is off.

[0057] At the same time, the difference between the peak wavelength of red light and the wavelength to which the human eye is sensitive is also large, and the distance between the peak wavelength of red light and the wavelength of maximum red light transmittance is small, so as to increase the intensity of the red light corresponding to the wavelength of maximum red light transmittance with the highest transmittance, and increase the brightness of the red light corresponding to the wavelength of maximum red light transmittance, which is beneficial to reduce the power consumption of red light and further reduce the overall power consumption of the display panel.

[0058] Because the distance between blue light and the wavelengths sensitive to the human eye is relatively large, reducing the transmittance of the blue color resist 323 for light at wavelengths sensitive to the human eye has little effect on reducing the reflectivity of the blue color resist 323 for light at wavelengths sensitive to the human eye. Therefore, in some embodiments of the present application, the peak wavelength of blue light and the wavelength of maximum blue light transmittance may not shift, but this is not limited to this.

[0059] In some embodiments, the peak wavelength of blue light is greater than or equal to 420 nanometers and less than or equal to 460 nanometers. Alternatively, the peak wavelength of blue light is greater than or equal to 425 nanometers and less than or equal to 458 nanometers. Alternatively, the peak wavelength of blue light is greater than or equal to 430 nanometers and less than or equal to 455 nanometers. Alternatively, the peak wavelength of blue light is greater than or equal to 435 nanometers and less than or equal to 445 nanometers. For example, the peak wavelength of blue light can be 420 nanometers, 425 nanometers, 430 nanometers, 435 nanometers, 440 nanometers, 445 nanometers, 450 nanometers, 455 nanometers, or 460 nanometers.

[0060] In some embodiments, the wavelength of maximum blue light transmittance is greater than or equal to 420 nanometers and less than or equal to 460 nanometers. Alternatively, the wavelength of maximum blue light transmittance is greater than or equal to 425 nanometers and less than or equal to 458 nanometers. Alternatively, the wavelength of maximum blue light transmittance is greater than or equal to 430 nanometers and less than or equal to 455 nanometers. Alternatively, the wavelength of maximum blue light transmittance is greater than or equal to 435 nanometers and less than or equal to 445 nanometers. For example, the wavelength of maximum blue light transmittance can be 420 nanometers, 422 nanometers, 425 nanometers, 430 nanometers, 435 nanometers, 440 nanometers, 445 nanometers, 450 nanometers, 455 nanometers, or 460 nanometers.

[0061] In some embodiments, the blue light peak wavelength is greater than the blue light maximum transmittance wavelength.

[0062] In some embodiments, the absolute value of the difference between the blue light peak wavelength and the blue light maximum transmittance wavelength is greater than or equal to 0 nanometers and less than or equal to 15 nanometers. This can increase the intensity of the blue light at the maximum transmittance wavelength, which has the highest transmittance, and improve the brightness of the blue light at the maximum transmittance wavelength, thereby reducing the power consumption of the blue light and, in turn, the overall power consumption of the display panel.

[0063] Optionally, the absolute value of the difference between the peak wavelength of blue light and the wavelength of maximum blue light transmittance is greater than or equal to 1 nanometer and less than or equal to 12 nanometers. Optionally, the absolute value of the difference between the peak wavelength of blue light and the wavelength of maximum blue light transmittance is greater than or equal to 2 nanometers and less than or equal to 10 nanometers. Optionally, the absolute value of the difference between the peak wavelength of blue light and the wavelength of maximum blue light transmittance is greater than or equal to 3 nanometers and less than or equal to 8 nanometers.

[0064] In some embodiments, the absolute value of the difference between the blue light peak wavelength and the wavelength of maximum blue light transmittance is smaller than the absolute value of the difference between the green light peak wavelength and the wavelength of maximum green light transmittance. This configuration can further reduce the absolute value of the difference between the blue light peak wavelength and the wavelength of maximum blue light transmittance, thereby increasing the brightness of the blue light corresponding to the wavelength of maximum blue light transmittance and further reducing the power consumption of the blue light.

[0065] In a specific embodiment, as shown in FIG2 , the abscissa of point GF is 523 to 528 nanometers, and the ordinate of point GF is 0.73 to 0.76. The abscissa of point GL is 528 to 530 nanometers, and the ordinate of point GL is 1. The abscissa of point RF is 642 to 645 nanometers, and the ordinate of point RF is 0.57 to 0.58. The abscissa of point RL is 630 to 635 nanometers, and the ordinate of RL is 1. The abscissa of point BF is 453 to 457 nanometers, and the ordinate of point BF is 0.71 to 0.73. The abscissa of point BL is 455 to 460 nanometers, and the ordinate of point BL is 1.

[0066] When the color filter layer 32 and the light-emitting device layer 21 of the present application adopt the design shown in Figure 2, the reflectivity of the display panel to light with a wavelength greater than or equal to 380 nanometers and less than or equal to 780 nanometers is 6.0% to 6.3%. That is, the display panel of the present application has a low emissivity to visible light, which can improve the problem of insufficient blackness of the display panel when the screen is off. At the same time, compared with the brightness of 365.47 nit of white light emitted by the display panel in the related art, the brightness of white light emitted by the display panel of the present application is 578.31 nit, which increases the luminous efficiency of the display panel by 58.23%, significantly improving the brightness of the display panel and helping to reduce the power consumption of the display panel.

[0067] Optionally, the display panel has a reflectivity of less than or equal to 6% for light with a wavelength greater than or equal to 380 nanometers and less than or equal to 780 nanometers. Optionally, the display panel has a reflectivity of less than or equal to 5.5% for light with a wavelength greater than or equal to 380 nanometers and less than or equal to 780 nanometers.

[0068] Combined with the foregoing, it can be seen that compared to related technologies, in this application, the green light peak wavelength and the wavelength of maximum green light transmittance are simultaneously blue-shifted, and the red light peak wavelength and the wavelength of maximum red light transmittance are simultaneously red-shifted. This reduces the reflectivity of the green color resist 322 and the red color resist 321 of the color filter layer of the display panel to the wavelengths of ambient light sensitive to the human eye, thereby reducing the flux of ambient light wavelengths sensitive to the human eye incident on the human eye, and improving the problem of insufficient blackness of the display panel 100 when the screen is off. At the same time, the light intensity of the wavelength of maximum green light transmittance and the wavelength of maximum red light emitted by the display panel 100 are both greater, increasing the brightness of the green and red lights, which helps reduce the power consumption corresponding to the green and red lights, and thus reduces the overall power consumption of the panel when displaying.

[0069] It should be noted that in the present application, the blue shift of the green light peak wavelength and the red shift of the red light peak wavelength can be achieved by adjusting the material composition of the green organic light-emitting layer 241 and the material composition of the red organic light-emitting layer 231, respectively. The blue shift of the green light maximum transmittance wavelength and the red shift of the red light maximum transmittance wavelength can be achieved by adjusting the material composition of the green color resist 322 and the red color resist 321, respectively.

[0070] It should also be noted that for monochromatic light, the human eye's sensitivity decreases in the order of green, red, and blue light. Furthermore, due to the inherent nature of the luminescent material, green light has a higher luminous efficiency and consumes less current, while blue light has a lower luminous efficiency and consumes more current. This results in a higher proportion of blue light power consumption in conventional technologies. In this application, the luminance of blue light can be increased to reduce the corresponding power consumption of blue light, thereby further reducing the power consumption of the display panel 100.

[0071] Please refer to FIG. 3 , which shows the transmission spectra of red color resist, green color resist, and blue color resist according to some other embodiments of the present application.

[0072] As shown in FIG3 , in some embodiments, the maximum transmittance of the transmission spectrum CFB of the blue color filter 323 is greater than the maximum transmittance of the transmission spectrum CFG of the green color filter 322. Specifically, the ordinate of the midpoint BF1 of the transmission spectrum CFB of the blue color filter 323 in FIG3 is greater than the ordinate of the midpoint GF1 of the transmission spectrum CFG of the green color filter 322 in FIG3 . This configuration increases the maximum transmittance of the blue light emitted by the blue light emitting unit 25 through the blue color filter 323, thereby increasing the brightness of the blue light and reducing the power consumption of the blue light. Furthermore, the maximum transmittance of the green light emitted by the green light emitting unit 24 through the green color filter 322 is relatively reduced. Correspondingly, the transmittance of the green color filter 322 for light at wavelengths sensitive to the human eye is also reduced, the absorption rate of the green color filter 322 for light at wavelengths sensitive to the human eye is increased, and the reflectivity of the green color filter 322 for light at wavelengths sensitive to the human eye is reduced. This further reduces the reflectivity of the color filter layer 32 for light at wavelengths sensitive to the human eye, further improving the problem of insufficient blackness of the display panel 100 when the screen is off.

[0073] In some embodiments, the maximum transmittance of the transmission spectrum CFB of the blue color resist 323 is greater than the maximum transmittance of the transmission spectrum CFR of the red color resist 321. Specifically, the ordinate of the midpoint BF1 of the transmission spectrum CFB of the blue color resist 323 in FIG3 is greater than the ordinate of the midpoint RF1 of the transmission spectrum CFR of the red color resist 321 in FIG3 . With this configuration, the maximum transmittance of the red light emitted by the red light emitting unit 23 through the red color resist 321 is relatively reduced. Furthermore, the transmittance of the red color resist 321 at wavelengths sensitive to the human eye is also reduced, the absorptivity of the red color resist 321 at wavelengths sensitive to the human eye is increased, and the reflectivity of the red color resist 321 at wavelengths sensitive to the human eye is reduced. This further reduces the reflectivity of the color filter layer 32 at wavelengths sensitive to the human eye, further improving the problem of insufficient blackness of the display panel 100 when the screen is off.

[0074] In some embodiments, the maximum transmittance of the transmission spectrum CFB of the blue color resist 323 is greater than or equal to 0.6, the maximum transmittance of the transmission spectrum CFG of the green color resist 322 is greater than or equal to 0.45, and the maximum transmittance of the transmission spectrum CFR of the red color resist 321 is greater than or equal to 0.55. This configuration ensures that the maximum transmittance of the transmission spectrum CFB of the blue color resist 323 is greater than the maximum transmittance of the transmission spectrum CFG of the green color resist 322 and the maximum transmittance of the transmission spectrum CFG of the red color resist 321.

[0075] In some embodiments, the maximum transmittance of the transmission spectrum CFB of the blue color resist 323 is less than or equal to 0.95. This configuration increases the maximum transmittance of the blue color resist 323 to the blue light emitted by the blue light emitting unit 25 while reducing the manufacturing difficulty of the blue color resist 323.

[0076] Optionally, the maximum transmittance of the transmission spectrum CFB of the blue color resist 323 is greater than or equal to 0.65 and less than or equal to 0.9. Optionally, the maximum transmittance of the transmission spectrum CFB of the blue color resist 323 is greater than or equal to 0.7 and less than or equal to 0.85. Optionally, the maximum transmittance of the transmission spectrum CFB of the blue color resist 323 is greater than or equal to 0.72 and less than or equal to 0.8.

[0077] In some embodiments, the maximum transmittance of the transmission spectrum CFG of the green color resist 322 is less than or equal to 0.75. This configuration results in a relatively low maximum transmittance of the green light emitted by the green light emitting unit 24 through the green color resist 322, reducing the transmittance of the green color resist 322 to light of wavelengths sensitive to the human eye and lowering the reflectivity of the green color resist 322 to light of wavelengths sensitive to the human eye. This further reduces the reflectivity of the color filter layer 32 of the display panel 100 to wavelengths sensitive to the human eye when the screen is off, reducing light of wavelengths sensitive to the human eye incident on the human eye, and improving the problem of insufficient blackness of the display panel 100 when the screen is off.

[0078] Optionally, the maximum transmittance of the transmission spectrum CFG of the green color resist 322 is greater than, equal to, less than 0.5 and less than 0.75. Optionally, the maximum transmittance of the transmission spectrum CFG of the green color resist 322 is greater than, equal to, less than 0.55 and less than 0.72. Optionally, the maximum transmittance of the transmission spectrum CFG of the green color resist 322 is greater than, equal to, less than 0.58 and less than 0.71.

[0079] In some embodiments, the maximum transmittance of the transmission spectrum CFR of the red color resist 321 is less than or equal to 0.75. This configuration reduces the maximum transmittance of the transmission spectrum CFR of the red color resist 321, thereby reducing the transmittance of the red color resist 321 to light of wavelengths sensitive to the human eye and lowering the reflectivity of the red color resist 321 to light of wavelengths sensitive to the human eye. This reduces the amount of light of wavelengths sensitive to the human eye incident on the human eye and improves the problem of insufficient black density of the display panel 100 when the screen is off.

[0080] Optionally, the maximum transmittance of the transmission spectrum CFR of the red color resist 321 is greater than or equal to 0.6 and less than or equal to 0.75. Optionally, the maximum transmittance of the transmission spectrum CFR of the red color resist 321 is greater than or equal to 0.65 and less than or equal to 0.72.

[0081] As shown in FIG3 , in a specific embodiment, the wavelength of maximum green light transmittance corresponding to the abscissa of point GF1 is 528 nm to 530 nm, and the maximum transmittance of the transmission spectrum CFG of the green color resist 322 corresponding to the ordinate of point GF1 is 0.71 to 0.74; the wavelength of maximum blue light transmittance corresponding to the abscissa of point BF1 is 448 nm to 452 nm, and the maximum transmittance of the transmission spectrum CFB of the blue color resist 323 corresponding to the ordinate of point BF1 is 0.85 to 0.9; the wavelength of maximum red light transmittance corresponding to the abscissa of point RF1 is 630 nm to 632 nm, and the maximum transmittance of the transmission spectrum CFR of the red color resist 321 corresponding to the ordinate of point RF1 is 0.71 to 0.74.

[0083] The display panel 100 further includes a pixel definition layer 13 disposed on the driving circuit layer 12 and including a plurality of openings. The red organic light-emitting layer 231, the green organic light-emitting layer 241, and the blue organic light-emitting layer 251 are each disposed in the plurality of openings. A common cathode 26 is disposed on the pixel definition layer 13, the red organic light-emitting layer 231, the green organic light-emitting layer 241, and the blue organic light-emitting layer 251.

[0084] In some embodiments, the display panel 100 further includes a thin-film encapsulation layer 41. This acts as a barrier to moisture and oxygen, mitigating corrosion of the organic light-emitting layer. The thin-film encapsulation layer 41 includes two inorganic insulating layers and an organic insulating layer positioned between the two inorganic insulating layers.

In still other embodiments, the color filter layer 32 may also be disposed inside the thin film encapsulation layer 41.

[0086] In some embodiments, the display panel 100 further includes a touch layer 51. The touch layer 51 may include self-capacitive touch electrodes or mutual-capacitive touch electrodes. The touch layer 51 may be disposed between the thin-film encapsulation layer 41 and the color filter layer 32, with the color filter layer 32 located on the side of the touch layer 51 facing away from the base layer 11.
