Description
Technical field
[0001] The present application relates to the technical field of display technology and in particular to a display panel and a display device. State of the art
[0002] Organic light-emitting diode (OLED) displays offer advantages such as a wide viewing angle, high contrast, and fast response time. However, OLED displays exhibit insufficient darkness when the screen is turned off, which impairs the visual effect during this time.
[0003] Therefore, it is necessary to provide a technical solution to improve the technical problem of insufficient darkness in organic light-emitting diode display devices during screen shutdown. Disclosure of registration
[0004] The present application provides a display panel and a display device to improve the problem of insufficient darkness in the display panel and display device during screen shutdown.
[0005] In a first aspect, the present application provides a display panel comprising a substrate layer, a light-emitting component layer, and a color film layer. The light-emitting component layer is arranged on the substrate layer. The light-emitting component layer includes a red-light-emitting unit, a green-light-emitting unit, and a blue-light-emitting unit, which are spaced apart. A green-light emission spectrum of the green-light-emitting unit has a green-light peak wavelength greater than or equal to 495 nm and less than or equal to 530 nm. The color film layer is arranged on a light-exiting side of the light-emitting component layer.The color film layer comprises a red resistor, a green resistor, and a blue resistor, with the red resistor covering the red-emitting unit, the green resistor covering the green-emitting unit, and the blue resistor covering the blue-emitting unit. The transmission spectrum of the green resistor exhibits a green-light maximum transmission wavelength greater than or equal to 495 nm and less than or equal to 530 nm.
[0006] In a second aspect, the present application further provides a display device comprising a display panel mentioned above according to some of the embodiments mentioned. Beneficial effects
[0007] In the display panel and display device according to some embodiments of the present application, the maximum green light transmission wavelength is greater than or equal to 495 nm and less than or equal to 530 nm. This shifts the maximum green light transmission wavelength of the green color resistor towards shorter wavelengths; that is, the maximum green light transmission wavelength of the green color resistor is blueshifted. The difference between 555 nm and the maximum green light transmission wavelength is greater, so the transmission rate of the green color resistor for light at 555 nm decreases, and the absorption rate increases.Accordingly, the reflection of the green color resistor for 555 nm light is lower, the reflection of the display panel for 555 nm light during screen shutdown is reduced, and less 555 nm light is reflected into the human eye, thus improving the problem of insufficient darkness of the display panel during screen shutdown. Simultaneously, the green light peak wavelength is greater than or equal to 495 nm and less than or equal to 530 nm, so the green light peak wavelength and the green light maximum transmission wavelength are both blueshifted to reduce the difference between the green light maximum transmission wavelength and the green light peak wavelength.The light intensity of the green light, corresponding to the green light maximum transmission wavelength with the highest transmission, is increased to improve the brightness of the green light when displayed on the display panel, thus helping to reduce the overall power consumption of the display panel. Therefore, according to the embodiments of the present application, the display panel and display device can have low power consumption and improve the problem of insufficient darkness when the screen is turned off.

Obviously, the described embodiments represent only a part, but not all, of the embodiments of the present application. All other embodiments that a person skilled in the art in the relevant technical field could obtain without creative effort based on the embodiments of the present application fall within the scope of protection of the present application.
[0010] With reference to Fig. 1, shows Fig. Figure 1 shows a schematic sectional view of the structure of a display panel according to some embodiments of the present application. The display panel 100 comprises a substrate layer 11, a light-emitting component layer 21, and a light filter layer 31.
[0011] The substrate layer 11 plays a supporting role. The substrate layer 11 can be a glass substrate layer or a flexible substrate layer. In a specific embodiment, the substrate layer 11 can be a flexible substrate layer to make the display panel 100 flexible. The flexible substrate layer includes, but is not limited to, a polyimide layer.
[0012] The light filter layer 31 serves not only to reduce the reflection of ambient light and thus improve the display contrast, but also to reduce the thickness of the display panel 100 to ensure that the display panel 100 can implement a flexible display. The light filter layer 31 is arranged on the light-emitting side of the light-emitting component layer 21.
[0013] More precisely, the light filter layer 31 is arranged on a side of the light-emitting component layer 21 facing away from the substrate layer 11. The light filter layer 31 comprises a black matrix 33. The black matrix 33 has a plurality of openings 331 extending through the black matrix 33 along its thickness direction. The light filter layer 31 further comprises a color film layer 32. The color film layer 32 has a red color resistor 321, a green color resistor 322, and a blue color resistor 323. The red color resistor 321, the green color resistor 322, and the blue color resistor 323 are each arranged in the plurality of openings 331.
[0014] Regarding the Fig. 2 shows Fig. 2 an emission spectrum of a red light emitting unit, a green light emitting unit and a blue light emitting unit and a transmission spectrum of a red color resistor, a green color resistor and a blue color resistor according to some embodiments of the present application.
[0015] The transmission spectrum CFG of the green-color resistor 322 exhibits a green-light maximum transmission wavelength that corresponds to the abscissa of a point GF on the transmission spectrum CFG of the green-color resistor 322. At the green-light maximum transmission wavelength, the transmission spectrum CFG of the green-color resistor 322 exhibits a maximum transmission rate that corresponds to the ordinate of the point GF on the transmission spectrum CFG.
[0016] The transmission spectrum CFR of the red color resistor 321 exhibits a red-light maximum transmission wavelength that corresponds to an abscissa of the point RF on the transmission spectrum CFR of the red color resistor 321. At the red-light maximum transmission wavelength, the transmission spectrum CFR of the red color resistor 321 exhibits a maximum transmission rate that corresponds to an ordinate of the point RF on the transmission spectrum CFR.
[0017] The transmission spectrum CFB of the blue-color resistor 323 has a blue-light maximum transmission wavelength that corresponds to the abscissa of point BF on the transmission spectrum CFB of the blue-color resistor 323. At the blue-light maximum transmission wavelength, the transmission spectrum CFB of the blue-color resistor 323 exhibits a maximum transmission rate that corresponds to the ordinate of point BF on the transmission spectrum CFR.
[0018] The light-emitting component layer 21 serves for light emission. The light-emitting component layer 21 comprises a variety of light-emitting units 22. The variety of light-emitting units 22 includes 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 selected from organic light-emitting diodes, micro-light-emitting diodes (micro-LEDs), submillimeter light-emitting diodes (mini-LEDs), and quantum dot light-emitting diodes, etc.
[0019] To describe the technical solution of the present application, the plurality of light-emitting units 22 are all, but not limited to, organic light-emitting diodes (OLEDs). The red-light-emitting unit 23 comprises an organic red-light-emitting layer 231, a first anode 232, and a common cathode 26. The organic red-light-emitting layer 231 is arranged between the first anode 232 and the common cathode 26. The green-light-emitting unit 24 comprises an organic green-light-emitting layer 241, a second anode 242, and a common cathode 26. The organic green-light-emitting layer 241 is arranged between the second anode 242 and the common cathode 26. The blue-light-emitting unit 25 comprises an organic blue-light-emitting layer 251, a third anode 252, and a common cathode 26.Therefore, the red light-emitting unit 23, the green light-emitting unit 24 and the blue light-emitting unit 25 share the common cathode 26.
[0020] As in Fig. As shown in Figure 1, the red color resistor 321 covers the red light-emitting unit 23, and an orthographic projection of the red color resistor 321 onto the substrate layer 11 and the orthographic projection of the red light-emitting unit 23 onto the substrate layer 11 overlap. In particular, the orthographic projection of the organic red light-emitting layer 231 onto the substrate layer 11 lies within the orthographic projection of the red color resistor 321 onto the substrate layer 11.
[0021] As in Fig. As shown in Figure 2, the red light emission spectrum ELR of the red light-emitting unit 23 has a red light peak wavelength that corresponds to an abscissa of the 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 exhibits a maximum luminous intensity that corresponds to an ordinate of the point RL on the red light emission spectrum ELR.
[0022] As in Fig. As shown in Figure 1, the green color resistor 322 covers the green light-emitting unit 24, and an orthographic projection of the green color resistor 322 on the substrate layer 11 and an orthographic projection of the green light-emitting unit 24 on the substrate layer 11 overlap. In particular, the orthographic projection of the organic green light-emitting layer 241 on the substrate layer 11 lies within the orthographic projection of the green color resistor 322 on the substrate layer 11.
[0023] As in Fig. As shown in Figure 2, the green light emission spectrum ELG of the green light-emitting unit 24 has a green light peak wavelength that corresponds to the abscissa of a point GL on the green light emission spectrum ELG of the green light-emitting unit 24. At the green light peak wavelength, the green light emission spectrum ELG of the green light-emitting unit 24 has a maximum light intensity that corresponds to the ordinate of the point GL on the green light emission spectrum ELG.
[0024] As in Fig. As shown in Figure 1, the blue color resistor 323 covers the blue light-emitting unit 25, and an orthographic projection of the blue color resistor 323 on the substrate layer 11 and an orthographic projection of the blue light-emitting unit 25 on the substrate layer 11 overlap. In particular, the orthographic projection of the organic blue light-emitting layer 251 on the substrate layer 11 lies within the orthographic projection of the blue color resistor 323 on the substrate layer 11.
[0025] As in Fig. As shown in Figure 2, the blue light emission spectrum ELB of the blue light-emitting unit 25 has a blue light peak wavelength that corresponds to the abscissa of a 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 that corresponds to the ordinate of the point BL on the blue light emission spectrum ELB.
[0026] In this technology, a polarizer with a lower transmission rate is replaced by a color film layer with a higher transmission rate to improve the light emission efficiency of the display panel. However, removing the polarizer can lead to high reflection of ambient light from the display panel, resulting in insufficient darkness of the display panel when the screen is turned off and thus reducing the visual effectiveness of the display panel during this time.
[0027] In light of the problem in the prior art, the present application reduces the transmission rate of the color film layer 32 for light with a wavelength of 555 nm, thereby increasing the absorption rate of the color film layer 32 for light with a wavelength of 555 nm. This reduces the reflection of ambient light with a wavelength of 555 nm incident on the color film layer 32 of the display panel 100 when the screen is switched off, and less light with a wavelength of 555 nm is reflected by the display panel 100 into the human eye when the screen is switched off. This improves the problem of insufficient darkness of the display panel 100 when the screen is switched off.
[0028] The analysis shows that since 555 nm lies in a wavelength band of green light, increasing the distance between 555 nm and the green light maximum transmission wavelength, for example, shifting the green light maximum transmission wavelength towards shorter wavelengths (blueshift), reduces the transmission rate of the green color resistor 322 with respect to 555 nm light, and increases the absorption rate of the green color resistor 322 with respect to 555 nm light. Correspondingly, the reflection rate of the green color resistor 322 with respect to 555 nm light is lower, and the reflection rate of the color film layer 32 of the display panel 100 with respect to 555 nm light is reduced, thus improving the problem of insufficient darkness of the display panel 100 when the screen is turned off.Simultaneously, the difference between the green light peak wavelength and the green light maximum transmission wavelength must be smaller to ensure that the light intensity of the green light maximum transmission wavelength penetrating the green color resistor 322, which has the highest transmission rate, is greater. To reduce the difference between the green light peak wavelength and the green light maximum transmission wavelength, the distance between 555 nm and the green light peak wavelength can also be increased, thus shifting the green light peak wavelength towards shorter wavelengths (blueshift) to further increase the difference between 555 nm and the green light peak wavelength.
[0029] What is special about the present application is, as in Fig. Figure 2 shows that the maximum green light transmission wavelength (corresponding to the abscissa of point GF) is greater than or equal to 495 nm and less than or equal to 530 nm, and the peak green light wavelength (corresponding to the abscissa of point GL) is greater than or equal to 495 nm and less than or equal to 530 nm. In this way, compared to a maximum green light transmission wavelength greater than 530 nm (e.g., any wavelength between 532 nm and 540 nm), the maximum green light transmission wavelength of the green color resistor is shifted towards shorter wavelengths in the prior art; that is, the maximum green light transmission wavelength of the green color resistor is blueshifted. The greater the difference between 555 nm and the maximum green light transmission wavelength, the lower the transmission rate of the green color resistor for light at 555 nm, and the higher the absorption rate.Accordingly, the reflection rate of the green color resistor for 555 nm light is lower, which reduces the reflection rate of the display panel for 555 nm light during screen shutdown, and less 555 nm light is reflected into people's eyes, thus improving the problem of insufficient darkness of the display panel during screen shutdown.
[0030] Simultaneously, compared to green light peak wavelengths greater than 530 nm (e.g., any wavelength between 532 nm and 540 nm), the prior art uses green light peak wavelengths greater than or equal to 495 nm and less than or equal to 530 nm. This results in a combined blueshift of the green light peak wavelength and the green light maximum transmission wavelength, thus reducing the difference between the green light maximum transmission wavelength and the green light peak wavelength. The luminous intensity of the green light corresponding to the green light maximum transmission wavelength with the highest transmission rate is greater, thereby improving the brightness of the green light displayed on the panel and contributing to a reduction in the overall power consumption of the display panel.
[0031] Therefore, the green light maximum transmission wavelength is greater than or equal to 495 nm and less than or equal to 530 nm, and the green light peak wavelength is also greater than or equal to 495 nm and less than or equal to 530 nm, so that the display panel provided in the present embodiment has low power consumption and the problem of insufficient darkness during screen shutdown can be improved.
[0032] Optionally, the green light peak wavelength can be greater than or equal to 500 nm and less than or equal to 525 nm. Optionally, the green light peak wavelength can be greater than or equal to 505 nm and less than or equal to 520 nm. Optionally, the green light peak wavelength can be greater than or equal to 508 nm and less than or equal to 515 nm. For example, the green light peak wavelength can be 495 nm, 498 nm, 500 nm, 502 nm, 505 nm, 508 nm, 510 nm, 512 nm, 515 nm, 518 nm, 520 nm, 522 nm, 525 nm, 528 nm, or 530 nm.
[0033] Optionally, the maximum green light transmission wavelength can be greater than or equal to 498 nm and less than or equal to 525 nm. Optionally, the maximum green light transmission wavelength can be greater than or equal to 502 nm and less than or equal to 523 nm. Optionally, the maximum green light transmission wavelength can be greater than or equal to 505 nm and less than or equal to 518 nm. Optionally, the maximum green light transmission wavelength can be greater than or equal to 508 nm and less than or equal to 515 nm. For example, the maximum green light transmission wavelength can be 495 nm, 498 nm, 500 nm, 502 nm, 505 nm, 508 nm, 510 nm, 512 nm, 515 nm, 518 nm, 520 nm, 525 nm, 528 nm, or 530 nm.
[0034] In some embodiments, the absolute value of the difference between the green light peak wavelength and the green light maximum transmission wavelength is greater than or equal to 0 nm and less than or equal to 15 nm. With this arrangement, the difference between the green light peak wavelength and the green light maximum transmission wavelength is smaller, so the luminous intensity of the green light corresponding to the green light maximum transmission wavelength is greater. The green light corresponding to the green light maximum transmission wavelength not only has the maximum transmission rate when passing through the green color resistor 322, but also a higher brightness, further reducing the power consumption of the green light corresponding to the green light maximum transmission wavelength. Optionally, the absolute value of the difference between the green light peak wavelength and the green light maximum transmission wavelength is greater than or equal to 2 nm and less than or equal to 12 nm.
[0035] Optionally, the absolute value of the difference between the green light peak wavelength and the green light maximum transmission wavelength is greater than or equal to 2 nm and less than or equal to 10 nm. Optionally, the absolute value of the difference between the green light peak wavelength and the green light maximum transmission wavelength is greater than or equal to 3 nm and less than or equal to 8 nm. Optionally, the absolute value of the difference between the green light peak wavelength and the green light maximum transmission wavelength is greater than or equal to 1 nm and less than or equal to 6 nm. Optionally, the absolute value of the difference between the green light peak wavelength and the green light maximum transmission wavelength is greater than or equal to 2 nm and less than or equal to 5 nm.
[0036] In some embodiments, the green light peak wavelength is greater than or equal to the green light maximum transmission wavelength. This arrangement ensures a higher light intensity of the light corresponding to the green light maximum transmission wavelength, and reduces the distance by which the green light peak wavelength shifts towards shorter wavelengths, thereby reducing the difficulty of fabricating the organic green light-emitting layer 241.
[0037] In some embodiments, the difference between the sensitive wavelength of the human eye and the green light maximum transmission wavelength is greater than or equal to 20 nm, and the sensitive wavelength of the human eye is greater than or equal to 550 nm or 560 nm and less than or equal to 560 nm. With this arrangement, the difference between the sensitive wavelength of the human eye and the green light maximum transmission wavelength is greater, so the transmission rate of the green color resistor 322 with respect to light of the sensitive wavelength of the human eye is reduced, and the absorption rate is increased, thereby reducing the reflection of the green color resistor 322 with respect to light of the sensitive wavelength of the human eye and also reducing the reflection of the display panel 100 with respect to the sensitive wavelength of the human eye during screen shutdown.In the case where the human eye is sensitive to light of the sensitive wavelength of the human eye, the reflection of the display panel 100 towards the light of the sensitive wavelength of the human eye is reduced, the light of the sensitive wavelength of the human eye reflected into the human eye during the screen turning off of the display panel 100 is reduced, and less light of the sensitive wavelength of the human eye is reflected into the human eye, thereby improving the problem of insufficient darkness during the screen turning off of the display panel 100.
[0038] Simultaneously, this arrangement, as described above, increases the distance between the peak wavelength of the green light and the sensitive wavelength of the human eye, thereby reducing the distance between the maximum green transmission wavelength and the peak wavelength. The peak and maximum green transmission wavelengths are both blueshifted, ensuring that the light intensity of the green light corresponds to the wavelength with the highest transmission. This increases the brightness of the green light displayed on the Display Panel 100, which helps to reduce the power consumption of the Display Panel required for green light emission, as well as the overall power consumption of the Display Panel 100.
[0039] Therefore, according to some embodiments of the present application, the display panel 100 can have low power consumption and the problem of insufficient darkness during screen shutdown can be improved by ensuring that the difference between the sensitive wavelength of the human eye and the green light maximum transmission wavelength is greater than or equal to 20 nm.
[0040] Further analysis reveals that the difference between the minimum wavelength of red light and 555 nm is smaller than the difference between the maximum wavelength of blue light and 555 nm. Therefore, in this application, by increasing the difference between the maximum transmission wavelength of red light and the sensitive wavelength of the human eye, in particular by shifting the maximum transmission wavelength of red light towards longer wavelengths (redshift), the transmission rate of the red color resistor 321 is reduced for the sensitive wavelength of the human eye, thereby increasing the absorption rate of the red color resistor 321 for the sensitive wavelength of the human eye.When the display panel 100 is switched off, the absorption rate of the red color resistor 321 of the display panel 100 is higher with respect to the light of the sensitive wavelength of the human eye, but the reflection is lower, and the reflected light of the sensitive wavelength of the human eye that enters the eye is further reduced, thus further improving the problem of insufficient darkness of the display panel 100 when the screen is switched off. At the same time, the difference between the red light peak wavelength and the red light maximum transmission wavelength must be smaller to ensure the light intensity of the red light maximum transmission wavelength. In order for the red light peak wavelength to also be shifted towards longer wavelengths, the difference between the red light maximum transmission wavelength and the red light peak wavelength is reduced.
[0041] In some embodiments, the maximum red light transmission wavelength is greater than or equal to 625 nm and less than or equal to 650 nm, and the peak red light wavelength is greater than or equal to 625 nm and less than or equal to 640 nm. In this way, compared to conventional techniques where the maximum red light transmission wavelength is less than 625 nm, the maximum red light transmission wavelength shifts towards longer wavelengths (redshift). The transmission rate of the red resistor 321 with respect to light with a wavelength of 555 nm is reduced. Accordingly, the absorption rate of the red resistor 321 with respect to light with a wavelength of 555 nm is higher, and the reflection rate of the red resistor 321 with respect to light with a wavelength of 555 nm is lower.This further reduces the reflection of the color film layer 32 of the display panel 100 towards light with a wavelength of 555 nm when the screen is turned off, and less light with a wavelength of 555 nm is reflected from the display panel 100 into people's eyes when the screen is turned off, thus improving the problem of insufficient darkness of the display panel 100 when the screen is turned off.
[0042] Simultaneously, the red light peak wavelength is greater than or equal to 625 nm and less than or equal to 640 nm, compared to conventional technology where the red light peak wavelength is less than 625 nm (e.g., any wavelength between 620 nm and 624 nm). This shifts the red light peak wavelength and reduces the difference between the red light peak wavelength and the red light maximum transmission wavelength. This increases the light intensity of the red light corresponding to the red light maximum transmission wavelength with the highest transmission rate and also increases the brightness of the red light corresponding to the red light maximum transmission wavelength. This contributes to reducing the power consumption of the red light and further reduces the overall power consumption of the display panel.
[0043] Therefore, the red light maximum transmission wavelength is greater than or equal to 625 nm and less than or equal to 650 nm, and the red light peak wavelength is greater than or equal to 625 nm and less than or equal to 640 nm, so that the red light maximum transmission wavelength and the red light peak wavelength are redshifted, further improving the problem of insufficient darkness of the display panel during screen shutdown and reducing the power consumption of the display panel.
[0044] Optionally, the maximum red light transmission wavelength can be greater than or equal to 628 nm and less than or equal to 648 nm. Optionally, the maximum red light transmission wavelength can be greater than or equal to 632 nm and less than or equal to 645 nm. Optionally, the maximum red light transmission wavelength can be greater than or equal to 635 nm and less than or equal to 645 nm. For example, the maximum red light transmission wavelength can be 625 nm, 628 nm, 630 nm, 632 nm, 635 nm, 638 nm, 640 nm, 642 nm, 645 nm, 648 nm, or 650 nm.
[0045] Optionally, the red light peak wavelength is greater than or equal to 628 nm and less than or equal to 638 nm. Optionally, the red light peak wavelength is greater than or equal to 630 nm and less than or equal to 635 nm. For example, the red light peak wavelength can be 625 nm, 628 nm, 630 nm, 632 nm, 635 nm, 638 nm, or 640 nm.
[0046] In some embodiments, the absolute value of the difference between the red light maximum transmission wavelength and the red light peak wavelength is greater than or equal to 0 nm and less than or equal to 15 nm. With this arrangement, the difference between the red light peak wavelength and the red light maximum transmission wavelength is smaller, and the luminous intensity of the red light corresponding to the red light maximum transmission wavelength is greater. The red light corresponding to the red light maximum transmission wavelength not only has the maximum transmission rate when passing through the red color resistor 321, but also a higher brightness, further reducing the power consumption of the red light corresponding to the red light maximum transmission wavelength. Optionally, the absolute value of the difference between the red light peak wavelength and the red light maximum transmission wavelength is greater than or equal to 2 nm and less than or equal to 12 nm.Optionally, the absolute value of the difference between the red light peak wavelength and the red light maximum transmission wavelength is greater than or equal to 4 nm and less than or equal to 10 nm. Optionally, the absolute value of the difference between the red light peak wavelength and the red light maximum transmission wavelength is greater than or equal to 6 nm and less than or equal to 8 nm. Optionally, the absolute value of the difference between the red light peak wavelength and the red light maximum transmission wavelength is greater than or equal to 1 nm and less than or equal to 12 nm. Optionally, the absolute value of the difference between the red light peak wavelength and the red light maximum transmission wavelength is greater than or equal to 2 nm and less than or equal to 6 nm.
[0047] In some embodiments, the absolute value of the difference between the red light maximum transmission wavelength and the red light peak wavelength is greater than the absolute value of the difference between the green light peak wavelength and the green light maximum transmission wavelength. With this arrangement, the absolute value of the difference between the green light peak wavelength and the green light maximum transmission wavelength is significantly smaller, which is more advantageous for improving the brightness of the green light corresponding to the green light maximum transmission wavelength and for further reducing the power consumption of the green light.
[0048] In other embodiments, the absolute value of the difference between the red light maximum transmission wavelength and the red light peak wavelength can be smaller than the absolute value of the difference between the green light peak wavelength and the green light maximum transmission wavelength. In this arrangement, the absolute value of the difference between the red light maximum transmission wavelength and the red light peak wavelength is significantly smaller, which is beneficial for improving the brightness of the red light corresponding to the red light maximum transmission wavelength and for further reducing the power consumption of the red light. In some embodiments, the difference between the red light maximum transmission wavelength and the sensitive wavelength of the human eye is greater than 80 nm, and the difference between the red light peak wavelength and the sensitive wavelength of the human eye is also greater than 80 nm.In this arrangement, the difference between the red light maximum transmission wavelength and the sensitive wavelength of the human eye is greater, which reduces the transmission rate of the red resistor 321 with respect to light of the sensitive wavelength of the human eye. Correspondingly, the red resistor 321 has a higher absorption rate for light of the sensitive wavelength of the human eye, resulting in lower reflection from the red resistor 321 with respect to light of the sensitive wavelength of the human eye.The reflection of the color film layer 32 of the display panel 100 when the screen is switched off is further reduced, so that less light of the sensitive wavelength of the human eye is reflected from the display panel 100 into the human eye when the screen is switched off, thus improving the problem of insufficient darkness of the display panel 100 when the screen is switched off.
[0049] Simultaneously, the difference between the red light peak wavelength and the sensitive wavelength of the human eye is greater, while the difference between the red light peak wavelength and the red light maximum transmission wavelength is smaller. This increases the light intensity of the red light corresponding to the red light maximum transmission wavelength with the highest transmission rate, and also increases the brightness of the red light corresponding to the red light maximum transmission wavelength. This helps to reduce the power consumption of the red light and further decreases the overall power consumption of the display panel 100.
[0050] Since the distance between the blue light and the sensitive wavelength of the human eye is greater, reducing the transmission rate of the blue color resistor 323 with respect to the light of the sensitive wavelength of the human eye has only a minor effect on reducing the reflection of the blue color resistor 323 with respect to the light of the sensitive wavelength of the human eye. Therefore, in some embodiments of the present application, the peak wavelength of the blue light and the maximum transmission wavelength of the blue light cannot be shifted, but are not limited to this.
[0051] In some embodiments, the blue light peak wavelength is greater than or equal to 420 nm and less than or equal to 460 nm. Optionally, the blue light peak wavelength can be greater than or equal to 425 nm and less than or equal to 458 nm. Optionally, the blue light peak wavelength is greater than or equal to 430 nm and less than or equal to 455 nm. Optionally, the blue light peak wavelength can be greater than or equal to 435 nm and less than or equal to 445 nm. For example, the blue light peak wavelength can be 420 nm, 425 nm, 430 nm, 435 nm, 440 nm, 445 nm, 450 nm, 455 nm, or 460 nm.
[0052] In some embodiments, the maximum blue light transmission wavelength is greater than or equal to 420 nm and less than or equal to 460 nm. Optionally, the maximum blue light transmission wavelength is greater than or equal to 425 nm and less than or equal to 458 nm. Optionally, the maximum blue light transmission wavelength is greater than or equal to 430 nm and less than or equal to 455 nm. Optionally, the maximum blue light transmission wavelength is greater than or equal to 435 nm and less than or equal to 445 nm. For example, the maximum blue light transmission wavelength can be 420 nm, 422 nm, 425 nm, 430 nm, 435 nm, 440 nm, 445 nm, 450 nm, 455 nm, or 460 nm.
[0053] In some embodiments, the peak wavelength of the blue light is greater than the maximum transmission wavelength of the blue light.
[0054] In some embodiments, the absolute value of the difference between the blue light peak wavelength and the blue light maximum transmission wavelength is greater than or equal to 0 nm and less than or equal to 15 nm. This allows the light intensity of the blue light maximum transmission wavelength, which has the highest transmission rate, to be increased, and the brightness of the blue light maximum transmission wavelength can be improved, which helps to reduce the luminous flux consumption of the blue light and thus lower the overall power consumption of the display panel.
[0055] Optionally, the absolute value of the difference between the blue light peak wavelength and the blue light maximum transmission wavelength is greater than or equal to 1 nm and less than or equal to 12 nm. Optionally, the absolute value of the difference between the blue light peak wavelength and the blue light maximum transmission wavelength is greater than or equal to 2 nm and less than or equal to 10 nm. Optionally, the absolute value of the difference between the blue light peak wavelength and the blue light maximum transmission wavelength is greater than or equal to 3 nm and less than or equal to 8 nm.
[0056] In some embodiments, the absolute value of the difference between the blue light peak wavelength and the blue light maximum transmission wavelength is smaller than the absolute value of the difference between the green light peak wavelength and the green light maximum transmission wavelength. With this arrangement, the absolute value of the difference between the blue light peak wavelength and the blue light maximum transmission wavelength is significantly smaller, which improves the brightness of the blue light corresponding to the blue light maximum transmission wavelength and thus further reduces the power consumption of the blue light.
[0057] In a specific embodiment, as in Fig. As shown in Figure 2, the abscissa of point GF ranges from 523 nm to 528 nm, and the ordinate of point GF ranges from 0.73 to 0.76. The abscissa of point GL ranges from 528 nm to 530 nm, and the ordinate of point GL is 1. The abscissa of point RF ranges from 642 nm to 645 nm, and the ordinate of point RF is 0.57 to 0.58. The abscissa of point RL ranges from 630 nm to 635 nm, and the ordinate of point RL is 1. The abscissa of point BF ranges from 453 nm to 457 nm, and the ordinate of point BF is 0.71 to 0.73. The abscissa of point BL ranges from 455 nm to 460 nm, and the ordinate of point BL is 1.
[0058] If the color film layer 32 and the light-emitting component layer 21 of the present application are as described in the Fig. As depicted in Figure 2, the reflectance of the display panel for light with a wavelength greater than or equal to 380 nm and less than or equal to 780 nm is 6.0% to 6.3%. This means that the display panel of the present application has a lower emission rate of visible light, which can improve the problem of insufficient darkness of the display panel when the screen is switched off. At the same time, the brightness of the white light emitted by the display panel is 578.31 nits, compared to 365.47 nits in the prior art, thereby improving the light emitter efficiency of the display panel by 58.23% and significantly increasing the brightness of the display panel, which contributes to reducing the power consumption of the display panel.
[0059] Optionally, the reflection of the display panel for light with a wavelength greater than or equal to 380 nm and less than or equal to 780 nm is less than or equal to 6%. Optionally, the reflection of the display panel for light with a wavelength greater than or equal to 380 nm and less than or equal to 780 nm is less than or equal to 5.5%.
[0060] As can be seen from the foregoing, in the present application the green light peak wavelength and the green light maximum transmission wavelength are simultaneously blueshifted, while the red light peak wavelength and the red light maximum transmission wavelength are simultaneously redshifted in order to reduce the reflection of the green color resistor 322 and the red color resistor 321 of the color film layer of the display panel onto the light of the sensitive wavelength of the human eye under ambient light. This reduces the luminous flux of the sensitive wavelength of the human eye entering the human eye under ambient light and improves the problem of insufficient darkness of the display panel 100 when the screen is switched off.At the same time, both the light intensity of the green light maximum transmission wavelength and the light intensity of the red light maximum transmission wavelength emitted by the display panel 100 are greater, and the brightness of the green light and red light is improved, which helps to reduce the power consumption corresponding to the green light and the red light and thus reduce the overall power consumption when displaying the panel.
[0061] It should be noted that in the present application, the redshift of the green-light peak wavelength and the redshift of the red-light peak wavelength can each be achieved by adjusting the material composition of the organic green-light-emitting layer 241 and the organic red-light-emitting layer 231. The blueshift of the green-light maximum transmission wavelength and the redshift of the red-light maximum transmission wavelength can each be achieved by adjusting the material composition of the green-color resistor 322 and the red-color resistor 321.
[0062] It should also be noted that the sensitivity of the human eye to monochromatic light decreases in order of green light, red light, and blue light. Furthermore, due to the light-emitting materials themselves, the light-emitting efficiency of green light is higher and its current lower, while the light-emitting efficiency of blue light is lower and its current higher, resulting in higher power consumption for blue light in the prior art. In the present application, it is possible to increase the light-emitting brightness of the blue light in order to reduce its corresponding power consumption and thereby further decrease the power consumption of the display panel 100.
[0063] Referring to Fig. 3, shows Fig. 3 a transmission spectrum of a red color resistor, a green color resistor and a blue color resistor according to some other embodiments of the present application.
[0064] As in Fig. As shown in Figure 3, in some embodiments the maximum transmission of the transmission spectrum CFB of the blue resistor 323 is greater than the maximum transmission of the transmission spectrum CFG of the green resistor 322. In particular, the ordinate of point BF1 of the transmission spectrum CFB of the blue resistor 323 in Fig. 3 greater than the ordinate of point GF1 of the transmission spectrum CFG of the green color resistor 322 in Fig. 3. With this arrangement, the maximum transmission of the blue light emitted by the blue light emitting unit 25 and penetrating through the blue color resistor 323 is greater, the brightness of the blue light is increased and the power consumption of the blue light can be reduced.Furthermore, the maximum transmission of the green light emitted by the green light emitting unit 24 and penetrating the green color resistor 322 is relatively reduced, and accordingly the transmission of the green color resistor 322 for the light of the sensitive wavelength of the human eye is also reduced, the absorption rate of the green color resistor 322 for the light of the sensitive wavelength of the human eye is increased, and the reflection of the green color resistor 322 for the light of the sensitive wavelength of the human eye is reduced, thereby further reducing the reflection of the color film layer 32 for the light of the sensitive wavelength of the human eye and further improving the problem of insufficient darkness of the display screen 100 during screen shutdown.
[0065] In some embodiments, the maximum transmission CFB of the blue resistor 323 is greater than the maximum transmission CFR of the red resistor 321. In particular, the ordinate of point BF1 of the CFB transmission spectrum of the blue resistor 323 is Fig. 3 greater than the ordinate of point RF1 of the transmission spectrum CFR of the red color resistor 321 in Fig. 3. This arrangement relatively reduces the maximum transmission of the red light emitted by the red-light-emitting unit 23 and penetrating the red color resistor 321. Furthermore, the transmission of the red color resistor 321 relative to the sensitive wavelength of the human eye is also reduced, the absorption rate of the red color resistor 321 relative to light of the sensitive wavelength of the human eye is increased, the reflection of the red color resistor 321 relative to light of the sensitive wavelength of the human eye is reduced, and the reflection of the color film layer 32 relative to light of the sensitive wavelength of the human eye is further reduced, thereby further improving the problem of insufficient darkness of the display panel 100 during screen shutdown.
[0066] In some embodiments, the maximum transmission CFB of the blue resistor 323 is greater than or equal to 0.6, the maximum transmission CFG of the green resistor 322 is greater than or equal to 0.45, and the maximum transmission CFR of the red resistor 321 is greater than or equal to 0.55.

[0069] In some embodiments, the maximum transmission of the transmission spectrum CFG of the green-color resistor 322 is less than or equal to 0.75. With this arrangement, the maximum transmission of the green light emitted by the green-light-emitting unit 24 through the green-color resistor 322 is lower. The transmission of the green-color resistor 322 to light of the sensitive wavelength of the human eye is reduced, and the reflection of the green-color resistor 322 to light of the sensitive wavelength of the human eye is also reduced.This further reduces the reflection of the color film layer 32 of the display panel 100 during screen shutdown against the light of the sensitive wavelength of the human eye, reduces the light of the sensitive wavelength of the human eye entering the human eye, and improves the problem of insufficient darkness of the display panel 100 during screen shutdown.
[0070] Optionally, the maximum transmission of the transmission spectrum CFG of the green-color resistor 322 is greater than or equal to 0.5 and less than or equal to 0.75. Optionally, the maximum transmission of the transmission spectrum CFG of the green-color resistor 322 is greater than or equal to 0.55 and less than or equal to 0.72. Optionally, the maximum transmission of the transmission spectrum CFG of the green-color resistor 322 is greater than or equal to 0.58 and less than or equal to 0.71.

The maximum blue light transmission wavelength, corresponding to the abscissa of point BF1, lies between 448 nm and 452 nm, and the maximum transmission CFB of the transmission spectrum of the blue resistor 323, corresponding to the ordinate of point BF1, lies between 0.85 and 0.9.
