Description

Technical Field

[0001] This invention relates to the field of display technology, and more particularly to a display panel and a display device. Background Technology

[0002] In existing display panels, light-emitting devices that emit the same color generally improve display contrast by using color resists that transmit light with the same center wavelength. However, this approach cannot meet the diverse display requirements that need to transmit light with different center wavelengths. Summary of the Invention

[0003] This invention provides a display panel and a display device. By setting a first-band light-emitting color resist to correspond to a first-band color pixel, wherein the first-band color pixel includes at least two light-emitting devices that emit light of the same color, and the first-band light-emitting color resist includes at least two sub-color resists that transmit light of different center wavelengths, the corresponding light-emitting devices can be controlled to emit light according to different display requirements, thereby improving the application scenarios of the display panel.

[0004] In a first aspect, embodiments of the present invention provide a display panel including a first band color pixel, wherein a first band color pixel includes at least two light-emitting devices that emit light of the same color.

[0005] The color resist layer includes a first-band light-emitting color resist, which corresponds to a first-band color pixel. The first-band light-emitting color resist includes at least two sub-color resists that transmit light with different center wavelengths.

[0020] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, although the drawings described below are some specific embodiments of the present invention, those skilled in the art can extend and extend the basic concepts of the device structure, driving method and manufacturing method disclosed and indicated by various embodiments of the present invention to other structures and drawings. Undoubtedly, these should all be within the scope of the claims of the present invention.

[0021] Figure 1 This is a schematic diagram of the structure of a display panel provided in an embodiment of the present invention. Figure 2 yes Figure 1 See the schematic diagram of the cross-section along the AA' direction. Figure 1 and Figure 2The display panel includes a first-band color pixel 10, and each first-band color pixel 10 includes at least two light-emitting devices 110 that emit light of the same color. A color resist layer 02 includes a first-band light-emitting color resist 20, which corresponds to the first-band color pixel 10. The first-band light-emitting color resist 20 includes at least two sub-color resists 210 that transmit light of different center wavelengths.

[0022] Specifically, such as Figure 1 and Figure 2 As shown, the display panel includes an array substrate 100 and sub-pixels 01 located on the array substrate 100. The array substrate 100 can be a low-temperature polycrystalline silicon array substrate, an IGZO (indium gallium zinc oxide) array substrate, or other types of substrates with TFT arrays. The array substrate 100 has multiple driving circuits (not shown) for driving the sub-pixels 01. Each driving circuit includes at least one thin-film transistor (TFT) T, which drives the sub-pixels 01 to emit light. The TFT T can have a top-gate structure or a bottom-gate structure. The structure of the TFT is not limited here. For example, if the TFT T has a bottom-gate structure, the array substrate 100 may include a buffer layer, a gate metal layer, a first insulating layer, an active layer, a second insulating layer, and a source / drain metal layer stacked sequentially. The channel of the transistor is located in the active layer, the gate of the transistor is located in the gate metal layer, and the source and drain of the transistor are located in the source / drain metal layers. It should be noted that the specific structure of the pixel driving circuit in the embodiments of the present invention is not limited. It may include 2 transistors and 1 storage capacitor, i.e., a "2T1C" driving circuit, or it may include 7 transistors and 1 storage capacitor, i.e., a "7T1C" driving circuit, as long as it can drive the sub-pixel 01 to emit light and display normally.

[0023] Sub-pixel 01 includes an anode, a light-emitting functional layer, and a cathode sequentially disposed near the array substrate 100. The drain of the thin-film transistor T is connected to the anode. Furthermore, the light-emitting functional layer can be a stack of layers including a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, and an electron injection layer. Specifically, when no voltage is applied to the anode and cathode, sub-pixel 01 does not emit light. When a voltage is applied to the anode and cathode, the anode injects holes into the hole injection layer, and the cathode injects electrons into the electron injection layer. The holes and electrons recombine in the light-emitting layer to form photoexcitons, radiating light.

[0024] The display panel also includes a color resist layer 02, which is disposed on the side of the sub-pixel 01 away from the array substrate 100, i.e., the color resist layer 02 is located on the light-emitting side of the sub-pixel 01. The color resist layer 02 includes multiple light-emitting color resists of different colors. Thus, the light emitted from the sub-pixel 01 with the first color of light emission can still maintain the first color after passing through the light-emitting color resist. When ambient light enters the display panel through the light-emitting color resist and is reflected in each film layer of the display panel, the light-emitting color resist can filter out other colors of light in the reflected light, allowing only the first color of light in the reflected light to pass through, thereby preventing the light emission accuracy of the sub-pixel 01 from being affected by ambient light. In the prior art, sub-pixels 01 emitting the same color are usually provided with light-emitting color resists of corresponding colors to transmit light, and these light-emitting color resists can transmit light with the same center wavelength to improve display contrast. However, when there is a display requirement that light-emitting color resists of corresponding colors need to transmit light with different center wavelengths, this cannot meet different display requirements.

[0025] Therefore, in this embodiment of the invention, sub-pixel 01 includes a first band color pixel 10, and color resist layer 02 includes a first band light-emitting color resist 20. The first band color pixel 10 corresponds to the first band light-emitting color resist 20. Light emitted from the first band color pixel 10 with the first band color is transmitted through the first band light-emitting color resist 20. Each first band color pixel 10 includes at least two light-emitting devices 110 that emit light of the same color, and the first band light-emitting color resist 20 includes at least two sub-color resists 210 that transmit light of different center wavelengths. Thus, the two light-emitting devices 110 that emit light of the same color can be respectively matched with the two sub-color resists 210 that transmit light of different center wavelengths. In this way, the light-emitting device 110 corresponding to the sub-color resist 210 that transmits light of the first band color pixel 10 can be controlled to emit light according to the different transmission center wavelength requirements of the first band color pixel 10 in the display panel, thereby meeting different display requirements and improving the application scenarios of the display panel.

[0026] In summary, the display panel provided by the embodiments of the present invention includes a first-band color pixel comprising at least two light-emitting devices emitting light of the same color, and a first-band light-emitting color resist comprising at least two sub-color resists transmitting light of different center wavelengths. The first-band color pixel is configured to correspond to the first-band light-emitting color resist, wherein the two light-emitting devices emitting light of the same color are respectively corresponding to the two sub-color resists transmitting light of different center wavelengths. Thus, according to the different transmission center wavelength requirements of the first-band color pixel in the display panel, the light-emitting device 110 corresponding to the sub-color resist transmitting the center wavelength can be controlled to emit light, that is, different working modes can be switched to meet different display requirements, thereby improving the application scenarios of the display panel.

[0027] Optionally, based on the above embodiments, see also... Figure 2The light-emitting device 110 in the same first-band color pixel 10 includes a first light-emitting device 111 and a second light-emitting device 112. The first-band light-emitting color resist 20 includes a first sub-band light-emitting color resist 211 and a second sub-band light-emitting color resist 212. Along the direction from the first-band light-emitting color resist 20 to the light-emitting device 110, the first sub-band light-emitting color resist 211 overlaps with the first light-emitting device 111 at least, and the second sub-band light-emitting color resist 212 overlaps with the second light-emitting device 112 at least. The first-band color is the color corresponding to light in the 380nm-500nm wavelength range. The center wavelength of the transmitted light from the first sub-band light-emitting color resist 211 is less than the center wavelength of the transmitted light from the second sub-band light-emitting color resist 212, or the maximum wavelength of light allowed to pass through the first sub-band light-emitting color resist 211 is less than the maximum wavelength of light allowed to pass through the second sub-band light-emitting color resist 212.

[0028] Specifically, such as Figure 2 As shown, the light-emitting device 110 in the same first-band color pixel 10 includes a first light-emitting device 111 and a second light-emitting device 112. The first light-emitting device 111 and the second light-emitting device 112 emit light of the same color. The first-band color can be the color corresponding to light in the wavelength range of 380nm-500nm. That is, the light emitted by the first light-emitting device 111 and the second light-emitting device 112 in the same first-band color pixel 10 is the first-band color. On the light-emitting side of the first light-emitting device 111 and the second light-emitting device 112, a first-band light-emitting color resist 20 is also provided. The first-band light-emitting color resist 20 includes a first sub-band light-emitting color resist 211 and a second sub-band light-emitting color resist 212. The first sub-band light-emitting color resist 211 and the second sub-band light-emitting color resist 212 are respectively provided corresponding to the first light-emitting device 111 and the second light-emitting device 112. That is, along the direction of the first-band light-emitting color resist 20 pointing to the light-emitting device 110, the first sub-band light-emitting color resist 211 has at least The second sub-band light-emitting color filter 212 overlaps with the first light-emitting device 111, and at least overlaps with the second light-emitting device 112. Thus, the first sub-band light-emitting color filter 211 and the second sub-band light-emitting color filter 212 respectively filter the light emitted by the first and second light-emitting devices 111 and 112. Since the center wavelength of the transmitted light from the first sub-band light-emitting color filter 211 is smaller than the center wavelength of the transmitted light from the second sub-band light-emitting color filter 212, the first sub-band light-emitting color filter 211 can transmit light with a smaller center wavelength in the first band color emitted by the first light-emitting device 111, and the second sub-band light-emitting color filter 212 can transmit light with a larger center wavelength in the first band color emitted by the second light-emitting device 112. Therefore, depending on the center wavelength requirement of the first band color, the first light-emitting device 111 or the second light-emitting device 112 can be controlled to emit light in different operating modes to meet different display requirements, thus expanding the application scenarios of the display panel.

[0029] It should be noted that in the actual measurement process, since the center wavelength is relatively flat and not easy to determine and compare, the first sub-band light-emitting color resist 211 and the second sub-band light-emitting color resist 212 can also be set according to the maximum wavelength of the light that can be transmitted. That is, the maximum wavelength of the light that can be transmitted by the first sub-band light-emitting color resist 211 is less than the maximum wavelength of the light that can be transmitted by the second sub-band light-emitting color resist 212, which can achieve the same effect.

[0030] It should also be noted that the embodiments of the present invention do not limit the specific color of the first band color, but only require that the color corresponds to the light in the band range of 380nm-500nm. In addition, to more clearly illustrate the technical solution of the present invention, the first band color is described below as blue.

[0031] Optional, see below Figure 2 In the first working state, the first light-emitting device 111 in the first band color pixel 10 emits light, and in the second working state, the second light-emitting device 112 in the first band color pixel 10 emits light.

[0032] Specifically, the ambient light intensity in the first working state is greater than that in the second working state. For example, the first working state can be the state in which the display panel works during the day, and the second working state can be the state in which the display panel works at night. In the first working state, only the first light-emitting device 111 in the first band color pixel 10 can be set to emit light, so that the first sub-band light-emitting color resist 211, which overlaps with the first light-emitting device 111 at least partially, can filter the light and transmit the light with a smaller center wavelength in the color light of the first band color emitted by the first light-emitting device 111, that is, transmit the high-frequency blue light in the blue light emitted by the first light-emitting device 111, so as to ensure the display color gamut of the display panel and improve the display effect of the display panel. In the second working state, only the second light-emitting device 112 in the first band color pixel 10 can be set to emit light, so that the second sub-band light-emitting color filter 212, which at least partially overlaps with the second light-emitting device 112, can filter the light. The light with a larger center wavelength in the color light of the first band color emitted by the second light-emitting device 112 is transmitted, that is, the low-frequency blue light in the blue light emitted by the second light-emitting device 112 is transmitted. The high-frequency blue light is filtered by the second sub-band light-emitting color filter 212, so as to avoid the stimulation of the human eye by the high-frequency blue light and affect the user's sleep. In this way, different working modes can be switched according to different application scenarios, improving the user experience.

[0033] Optionally, the center wavelength of the transmitted light from the first sub-band light-emitting color filter 211 is less than 460 nm, and the center wavelength of the transmitted light from the second sub-band light-emitting color filter 212 is greater than 460 nm.

[0034] Specifically, high-frequency blue light can be blue light with a center wavelength of around 450nm, while low-frequency blue light can be blue light with a center wavelength greater than 460nm, with the center wavelength of high-frequency blue light being shorter than that of low-frequency blue light. Therefore, the center wavelength of the transmitted light from the first sub-band color filter 211 is set to be less than 460nm, so that the first sub-band color filter 211 transmits the high-frequency blue light emitted by the first light-emitting device 111, ensuring the display panel's color gamut and improving its display effect. The center wavelength of the transmitted light from the second sub-band color filter 212 is set to be greater than 460nm, so that the second sub-band color filter 212 transmits the low-frequency blue light emitted by the second light-emitting device 112, thereby avoiding the stimulation of the human eye by high-frequency blue light.

[0035] In other embodiments, the center wavelength of the transmitted light from the first sub-band color filter 211 is between 440nm and 460nm, and the center wavelength of the transmitted light from the second sub-band color filter 212 is between 480nm and 500nm.

[0036] Preferably, the center wavelength of the transmitted light from the first sub-band light-emitting color resist 211 can be between 440nm and 460nm, which can further ensure that the first sub-band light-emitting color resist 211 transmits the high-frequency blue light emitted by the first light-emitting device 111, thus ensuring the color gamut of the display panel. The center wavelength of the transmitted light from the second sub-band light-emitting color resist 212 is between 480nm and 500nm, which can further ensure that the second sub-band light-emitting color resist 212 transmits the low-frequency blue light emitted by the second light-emitting device 112, thus avoiding the stimulation of the human eye by high-frequency blue light.

[0037] Optional, Figure 3 yes Figure 1 See another schematic diagram of the cross section along the AA' direction. Figure 3 The display panel also includes an array substrate 100. The projection of the first sub-band light-emitting color resist 211 onto the plane of the array substrate 100 covers the first light-emitting device 111, and the projection of the second sub-band light-emitting color resist 212 onto the plane of the array substrate 100 covers the second light-emitting device 112. The projection area of ​​the first light-emitting device 111 onto the plane of the array substrate 100 and the projection area of ​​the second light-emitting device 112 onto the plane of the array substrate 100 are different.

[0038] Specifically, such as Figure 3As shown, along the direction from the first-band light-emitting color resist 20 to the light-emitting device 110, the first sub-band light-emitting color resist 211 completely covers the first light-emitting device 111, and the second sub-band light-emitting color resist 212 completely covers the second light-emitting device 112. That is, the projection of the first sub-band light-emitting color resist 211 onto the plane of the array substrate 100 covers the first light-emitting device 111, and the projection of the second sub-band light-emitting color resist 212 onto the plane of the array substrate 100 covers the second light-emitting device 112. This ensures that the blue light emitted by the first light-emitting device 111 can pass through the first sub-band light-emitting color resist 211. 11. Filtering is performed, that is, high-frequency blue light is transmitted, and the final display is blue. The blue light emitted by the second light-emitting device 112 can be filtered by the second sub-band light-emitting color resist 212, that is, low-frequency blue light is transmitted, and the final display is blue-green. In addition, by setting the projection of the first sub-band light-emitting color resist 211 on the plane of the array substrate 100 to cover the first light-emitting device 111, and the projection of the second sub-band light-emitting color resist 212 on the plane of the array substrate 100 to cover the second light-emitting device 112, the problem of uneven display caused by the first band light-emitting color resist 20 not completely covering the light-emitting device 110 is avoided.

[0039] It should be noted that the projected area of ​​the first light-emitting device 111 on the plane of the array substrate 100 and the projected area of ​​the second light-emitting device 112 on the plane of the array substrate 100 are different. Those skilled in the art can set the projected area of ​​the first light-emitting device 111 on the plane of the array substrate 100 to be greater than the projected area of ​​the second light-emitting device 112 on the plane of the array substrate 100, or the projected area of ​​the first light-emitting device 111 on the plane of the array substrate 100 to be less than the projected area of ​​the second light-emitting device 112 on the plane of the array substrate 100 as needed. The present invention does not limit this. The two cases will be described below with reference to specific embodiments.

[0040] Optional, see below Figure 3 The projected area of ​​the first light-emitting device 111 on the plane of the array substrate 100 is smaller than the projected area of ​​the second light-emitting device 112 on the plane of the array substrate 100.

[0041] Specifically, because the center wavelength of the light transmitted by the second sub-band color filter 212 is greater than the center wavelength of the light transmitted by the first sub-band color filter 211, and because the second sub-band color filter 212 is positioned corresponding to the second light-emitting device 112, the second sub-band color filter 212 can transmit the light with a larger center wavelength in the blue light emitted by the second light-emitting device 112. In other words, the second sub-band color filter 212 transmits the low-frequency blue light in the blue light emitted by the second light-emitting device 112, while blocking the high-frequency blue light in the blue light emitted by the second light-emitting device 112. This will cause the brightness of the blue light ultimately emitted by the second light-emitting device 112 to be slightly lower than normal. Because the wavelength is low (longer wavelength, the color will have a certain greenish tint), the projected area of ​​the first light-emitting device 111 on the plane of the array substrate 100 can be set to be smaller than the projected area of ​​the second light-emitting device 112 on the plane of the array substrate 100. That is, by increasing the projected area of ​​the second light-emitting device 112 on the plane of the array substrate 100, the brightness of the blue light in the blue-green light emitted by the second light-emitting device 112 is made similar to the brightness of the blue light emitted by the first light-emitting device 111, or the brightness of the blue-green light emitted by the second light-emitting device 112 is made similar to the brightness of the color light emitted by other sub-pixels 01, thus ensuring the display uniformity of the display panel.

[0042] In yet another embodiment, Figure 4 yes Figure 1 See another schematic diagram of the cross section along the AA' direction. Figure 4 The projected area of ​​the first light-emitting device 111 on the plane of the array substrate 100 is greater than the projected area of ​​the second light-emitting device 112 on the plane of the array substrate 100.

[0043] Specifically, the size relationship between the projected areas of the first light-emitting device 111 and the second light-emitting device 112 on the plane of the array substrate 100 can be set according to the viewing angle requirements under different working states. For example, the first working state can be the state where the display panel works during the day, and the second working state can be the state where the display panel works at night. In the first working state, the viewing angle requirement of the display panel is biased towards a large viewing angle. Therefore, the projected area of ​​the first light-emitting device 111 on the plane of the array substrate 100 can be increased to make the viewing angle supported by the first light-emitting device 111 larger. In other words, in the first working state, the display effect of the display panel at a large viewing angle is further improved. In the second working state, the viewing angle requirement of the display panel is biased towards a small viewing angle. Therefore, the projected area of ​​the second light-emitting device 112 on the plane of the array substrate 100 can be set to be smaller, and the display effect of the display panel can be improved in combination with the static usage environment.

[0044] Optionally, the first light-emitting device 111 and the second light-emitting device 112 share the same vapor deposition opening. Specifically, when the first light-emitting device 111 and the second light-emitting device 112 are formed by vapor deposition, the same vapor deposition opening can be used. In this way, the distance between the first light-emitting device 111 and the second light-emitting device 112 can be reduced, thereby compressing the pixel size and simplifying the process.

[0045] Optional, see below Figure 2 The first light-emitting device 111 includes a first electrode 1110, a first light-emitting layer 1111, and a second electrode 1112 stacked together. The second light-emitting device 112 includes a third electrode 1120, a second light-emitting layer 1121, and a fourth electrode 1122 stacked together. The first electrode 1110 and the third electrode 1120 are formed synchronously using the same process. The first light-emitting layer 1111 and the second light-emitting layer 1121 are formed synchronously using the same process. The second electrode 1112 and the fourth electrode 1122 are formed synchronously using the same process.

[0046] Specifically, the first electrode 1110 and the third electrode 1120 can be anodes, and the second electrode 1112 and the fourth electrode 1122 can be cathodes. When a voltage is applied to the anode and cathode, the first light-emitting device 111 and the second light-emitting device 112 emit light. During fabrication, the first electrode 1110 and the third electrode 1120 can be formed using the same mask in the same fabrication process, eliminating the need to fabricate separate masks for the first electrode 1110 and the third electrode 1120, thus saving costs, reducing the number of processes, and improving production efficiency. The first light-emitting layer 1111 and the second light-emitting layer 1121 can be fabricated using the same mask in the same process, eliminating the need to fabricate separate masks for the first light-emitting layer 1111 and the second light-emitting layer 1121, thus saving costs, reducing the number of processes, and improving production efficiency. Similarly, the second electrode 1112 and the fourth electrode 1122 can be fabricated using the same mask in the same process, eliminating the need to fabricate separate masks for the second electrode 1112 and the fourth electrode 1122, thus saving costs, reducing the number of processes, and improving production efficiency.

[0047] Optional, Figure 5 yes Figure 1 See another schematic diagram of the cross section along the AA' direction. Figure 5 The first sub-band light-emitting color resist 20 points towards the light-emitting device 110, and the first sub-band light-emitting color resist 211 also overlaps with the second light-emitting device 112.

[0048] Specifically, such as Figure 5As shown, along the direction of the first-band light-emitting color resist 20 pointing towards the light-emitting device 110, the first sub-band light-emitting color resist 211 overlaps with the second light-emitting device 112. The first sub-band light-emitting color resist 211 also overlaps with the second sub-band light-emitting color resist 212. That is, along the direction of the first sub-band light-emitting color resist 211 pointing towards the light-emitting device 110, the first sub-band light-emitting color resist 211 includes the portion overlapping with the first light-emitting device 111 and the portion overlapping with the second light-emitting device 112. The blue light emitted by the first light-emitting device 111 passes through the first sub-band... The light emitted by the first light-emitting device 111 is filtered by the first sub-band light-emitting device 211 and the second sub-band light-emitting device 212. This makes the light emitted by the first light-emitting device 111 appear as blue light and the light emitted by the second light-emitting device 112 appear as blue-green light. Thus, depending on the different working modes of the display panel, the first light-emitting device 111 or the second light-emitting device 112 can be controlled to emit light, thereby meeting the display requirements of different working modes of the display panel and improving the application scenarios of the display panel.

[0049] It is understood that the first sub-band light-emitting color resist 211 includes a portion overlapping with the first light-emitting device 111 and a portion overlapping with the second light-emitting device 112. These two portions are continuous structures, or the first sub-band light-emitting color resist 211 is integrally formed.

[0050] It should be noted that the direction from the first-band light-emitting color resist 20 to the light-emitting device 110 should be such that the first sub-band light-emitting color resist 211 and the second light-emitting device 112 overlap. This embodiment of the invention does not restrict the relative positions of the first sub-band light-emitting color resist 211 and the second sub-band light-emitting color resist 212. The two positional relationships of the first sub-band light-emitting color resist 211 and the second sub-band light-emitting color resist 212 will be described below with reference to specific embodiments.

[0051] In one embodiment, see further. Figure 5 The second sub-band light-emitting color resist 212 is located on the side of the first sub-band light-emitting color resist 211 that is close to the second light-emitting device 112. The thickness of the first sub-band light-emitting color resist 211 that overlaps with the second light-emitting device 112 is less than the thickness of the first sub-band light-emitting color resist 211 that overlaps with the first light-emitting device 111.

[0052] Specifically, such as Figure 5As shown, along the direction of the first-band light-emitting color filter 20 pointing towards the light-emitting device 110, the second-band light-emitting color filter 212 is located on the side of the first-band light-emitting color filter 211 closest to the second light-emitting device 112. That is, the blue light emitted by the second light-emitting device 112 is first filtered by the second-band light-emitting color filter 212, and then filtered by the first-band light-emitting color filter 211. The center wavelength of the light transmitted through the second-band light-emitting color filter 212 is greater than the center wavelength of the light transmitted through the first-band light-emitting color filter 211. For example, the first-band light-emitting color filter 212... The first sub-band color filter 211 transmits light with a center wavelength less than 460nm, meaning it transmits more high-frequency blue light and less low-frequency blue light. The second sub-band color filter 212 transmits light with a center wavelength greater than 460nm, also transmitting more low-frequency blue light and less high-frequency blue light. Therefore, after passing through the second sub-band color filter 212 and the first sub-band color filter 211, the proportion of low-frequency blue light transmitted is greater than the proportion of high-frequency blue light, resulting in the light emitted by the second light-emitting device 112 ultimately appearing blue-green. Furthermore, since the first sub-band color filter 211 is superimposed on the second sub-band color filter 212 corresponding to the second light-emitting device 112, the first sub-band color filter 211 can assist in filtering unwanted colors, reducing the filtering burden on the first sub-band color filter 211.

[0053] Furthermore, along the direction from the first-band light-emitting color resist 20 to the light-emitting device 110, the thickness of the first sub-band light-emitting color resist 211 overlapping with the second light-emitting device 112 can be less than the thickness of the first sub-band light-emitting color resist 211 overlapping with the first light-emitting device 111. For example, along the direction from the first-band light-emitting color resist 20 to the light-emitting device 110, the thickness of the first sub-band light-emitting color resist 211 and the second sub-band light-emitting color resist 212 overlapping with the second light-emitting device 112 can be the same as the thickness of the first sub-band light-emitting color resist 211 overlapping with the first light-emitting device 111. This allows for a more uniform and balanced distribution of the light-emitting color resist 211. The presence of the second sub-band light-emitting color resist 212 in the corresponding portion of the second light-emitting device 112 can reduce the thickness of the first sub-band light-emitting color resist 211 at that position, thereby increasing the transmittance of that area and compensating for the brightness loss caused by the second sub-band light-emitting color resist 212. Furthermore, in this embodiment, since it is not necessary to increase the projected area of ​​the second light-emitting device 112 on the plane of the array substrate 100 to compensate for the final display brightness of the second light-emitting device 112, the projected area of ​​the second light-emitting device 112 on the plane of the array substrate 100 can be indirectly reduced, thereby improving the overall aperture ratio. Furthermore, since the first sub-band light-emitting color resist 20 points towards the light-emitting device 110, the first sub-band light-emitting color resist 211 covers the second sub-band light-emitting color resist 212. Therefore, compared to the scheme of setting the first sub-band light-emitting color resist 211 and the second sub-band light-emitting color resist 212 corresponding to the first light-emitting device 111 and the second light-emitting device 112, the stray light problem caused by the edge overlap of the first sub-band light-emitting color resist 211 and the second sub-band light-emitting color resist 212 can be avoided during the manufacturing process.

[0054] Optionally, the second sub-band color filter 212 includes indium tin oxide (ITO) or cuprous oxide (CO). Specifically, the second sub-band color filter 212 can be prepared by physical vapor deposition (PVD), and the material can be a narrow bandgap inorganic material, such as ITO or CO. Indium tin oxide is a substitutional solid solution, a transparent brown film or a yellowish-gray block, mainly used in the manufacture of liquid crystal displays, flat panel displays, plasma displays, touch screens, electronic paper, organic light-emitting diodes (OLEDs), antistatic coatings, transparent conductive coatings for EMI shielding, and various optical coatings. Its main characteristic is the combination of electrical conductivity and optical transparency, which is beneficial for improving the transmittance of the second sub-band color filter 212.

[0055] In yet another embodiment, Figure 6 yes Figure 1 See another schematic diagram of the cross section along the AA' direction. Figure 6 The second sub-band light-emitting color resist 212 is located on the side of the first sub-band light-emitting color resist 211 away from the second light-emitting device 112. The second sub-band light-emitting color resist 212 is made of the same material as the first sub-band light-emitting color resist 211, and the second sub-band light-emitting color resist 212 is doped with an absorbing material with a center wavelength of less than 460nm.

[0056] Specifically, such as Figure 6 As shown, along the direction from the first-band light-emitting color filter 20 to the light-emitting device 110, the second-band light-emitting color filter 212 is located on the side of the first-band color filter 211 away from the second light-emitting device 112. That is, the blue light emitted by the second light-emitting device 112 is first filtered by the first-band color filter 211, and then filtered by the second-band color filter 212. The second-band color filter 212 is made of the same material as the first-band color filter 211, and the second-band color filter 212 is doped with light whose center wavelength is less than 460nm. The second sub-band light-emitting color filter 212 absorbs light with a center wavelength less than 460nm, meaning it absorbs high-frequency blue light while allowing more low-frequency blue light to pass through. Meanwhile, the first sub-band light-emitting color filter 211 can be doped with light-absorbing materials with a center wavelength greater than 460nm, meaning it allows more high-frequency blue light to pass through and less low-frequency blue light to pass through. As a result, after the second light-emitting device 112 is filtered by the first and second sub-band light-emitting color filters 211 and 212, it ultimately displays a blue-green color. Furthermore, by setting the second sub-band light-emitting color resist 212 on the side of the first sub-band light-emitting color resist 211 away from the second light-emitting device 112, that is, along the direction of the first band light-emitting color resist 20 pointing to the light-emitting device 110, and setting the second sub-band light-emitting color resist 212 at the position overlapping with the second light-emitting device 112 to cover the first sub-band light-emitting color resist 211, the problem caused by the difficulty in controlling the edge process of the light-emitting color resist during the manufacturing process can be avoided.

[0057] Optional, see below Figure 1 and Figure 2 The shape of the light-emitting surface of the second sub-band color filter 212 is the same as the shape of the surface of the second light-emitting device 112 near the second sub-band color filter 212. Specifically, since the first sub-band color filter 211 overlaps with the second light-emitting device 112 along the direction from the first band color filter 20 to the light-emitting device 110, by setting the shape of the light-emitting surface of the second sub-band color filter 212 to be the same as the shape of the surface of the second light-emitting device 112 near the second sub-band color filter 212, it is ensured that the light emitted by the second light-emitting device 112, after passing through the first sub-band color filter 211, can also be filtered by the second sub-band color filter 212, which has the same shape as the surface of the second light-emitting device 112 near the second sub-band color filter 212. This avoids the problem of uneven display caused by light leakage due to the difference in shape between the light-emitting surface of the second sub-band color filter 212 and the surface of the second light-emitting device 112 near the second sub-band color filter 212.

[0058] Based on the above embodiments, Figure 7This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. See also... Figure 7 Multiple first-band color pixels 10 are arranged in an array, and the first light-emitting device 111 and the second light-emitting device 112 are arranged along the column direction of the array.

[0059] Specifically, such as Figure 7 As shown, the display panel includes sub-pixels 01, each sub-pixel 01 including first-band color pixels 10. Multiple first-band color pixels 10 are arranged in an array. Each first-band color pixel 10 includes at least two first light-emitting devices 111 and second light-emitting devices 112 that emit the same color light. The first light-emitting devices 111 and second light-emitting devices 112 are arranged along the column direction Y of the array. Since the first-band light-emitting color resist 20 points towards the light-emitting device 110, the first sub-band light-emitting color resist 211 overlaps at least with the first light-emitting device 111, and the second sub-band light-emitting color resist 212 overlaps at least with the second light-emitting device 112. Furthermore, the center wavelength of the transmitted light from the first sub-band light-emitting color resist 211 is smaller than that of the second sub-band light-emitting color resist 212. The center wavelength of the transmitted light from the sub-band light-emitting color filter 212, that is, the first light-emitting device 111 and the second light-emitting device 112 emitting blue light are filtered by the first sub-band light-emitting color filter 211 and the second sub-band light-emitting color filter 212 respectively, and finally displayed as blue light and blue-green light. Furthermore, by setting the first light-emitting device 111 that finally displays blue light and the second light-emitting device 112 that finally displays blue-green light to be arranged along the column direction Y of the array, the emitted light colors of the first light-emitting device 111 and the second light-emitting device 112 will not interfere with each other at different viewing angles along the row direction X of the array (the row direction X of the array can be set perpendicular to the column direction Y), thus avoiding the color shift problem at a specific angle.

[0060] Optional, see below Figure 7 The first light-emitting device 111 and the second light-emitting device 112 are arranged alternately along the column direction Y of the array. Specifically, as shown... Figure 7 As shown, the arrangement order of the first light-emitting device 111 and the second light-emitting device 112 of the first band color pixel 10 in the display panel can be the same, that is, along the column direction Y of the array, the first light-emitting device 111 and the second light-emitting device 112 are arranged alternately, which can improve the color shift problem at a large viewing angle in a specific direction.

[0061] Optionally, in other embodiments, Figure 8 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. See also... Figure 8 Along the column direction Y of the array, at least two first light-emitting devices 111 and / or at least two second light-emitting devices 112 are arranged adjacent to each other. Specifically, as shown... Figure 8As shown, along the column direction Y of the array, the arrangement order of the first light-emitting device 111 and the second light-emitting device 112 in different first band color pixels 10 can be different. For example, along the row direction X of the array, the arrangement direction of the first light-emitting device 111 and the second light-emitting device 112 in the same row of first band color pixels 10 is the same, while along the column direction X of the array, the arrangement order of the first light-emitting device 111 and the second light-emitting device 112 of two adjacent first band color pixels 10 is opposite, that is, there are at least two first light-emitting devices 111 and / or at least two second light-emitting devices 112 arranged adjacently, which can make the color shift distribution in each direction more uniform.

[0062] Optional, Figure 9 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention. See also... Figure 9 The display panel also includes an array substrate 100. In the same first band color pixel 10, the projection outlines of the first light-emitting device 111 and the second light-emitting device 112 on the plane of the array substrate 100 form a rectangular shape. The boundary line a of the first light-emitting device 111 and the second light-emitting device 112 is parallel to the two sides of the rectangle.

[0063] Specifically, such as Figure 9 As shown, the projection shape of the first light-emitting device 111 on the plane of the array substrate 100 can be a first rectangle, and the projection shape of the second light-emitting device 112 on the plane of the array substrate 100 can be a second rectangle. The length of the first rectangle can be equal to the width of the second rectangle, and the long side of the first rectangle is adjacent to the wide side of the second rectangle, so that the projection outlines of the first light-emitting device 111 and the second light-emitting device 112 on the plane of the array substrate 100 form a rectangular shape. There is also a boundary line a between the first light-emitting device 111 and the second light-emitting device 112 in the same first band color pixel 10. The boundary line a is parallel to the two wide sides of the rectangle formed by the first light-emitting device 111 and the second light-emitting device 112. In this way, by setting the projection outlines of the first light-emitting device 111 and the second light-emitting device 112 on the plane of the array substrate 100 to form a rectangular shape, the arrangement of the first band color pixels 10 can be simplified.

[0064] Optionally, based on the above embodiments, see also... Figure 8 The display panel also includes an array substrate 100. In the same first band color pixel 10, the projection outlines of the first light-emitting device 111 and the second light-emitting device 112 on the plane of the array substrate 100 form a rectangular shape or a rhombus shape. The boundary line a of the first light-emitting device 111 and the second light-emitting device 112 is parallel to the first diagonal b of the rectangle or rhombus.

[0065] Specifically, such as Figure 8As shown, the projection shape of the first light-emitting device 111 on the plane of the array substrate 100 can be a triangle, and the projection shape of the second light-emitting device 112 on the plane of the array substrate 100 can be a rectangle with a missing corner or a rhombus. Thus, the projection outlines of the first light-emitting device 111 and the second light-emitting device 112 on the plane of the array substrate 100 form a rectangular or rhomboid shape. The rectangle can be a rectangle rotated by a certain angle, or it can be understood as a rhombus with an interior angle of 90°. There is also a boundary line a between the first light-emitting device 111 and the second light-emitting device 112 in the same first-band color pixel 10. The boundary line a is parallel to the first diagonal b of the rectangle or rhombus formed by the first light-emitting device 111 and the second light-emitting device 112, that is, the boundary line a is parallel to the row direction X of the array. In this way, by setting the projection outlines of the first light-emitting device 111 and the second light-emitting device 112 on the plane of the array substrate 100 to form a rectangular or rhomboid shape, the arrangement of the first-band color pixels 10 can be simplified.

[0066] Based on the above embodiments, see below. Figure 8 The display panel comprises an array of multiple first-band color pixels 10, and a first light-emitting device 111 and a second light-emitting device 112 arranged along the column direction Y of the array. The display panel includes a first region AA and a second region AB arranged along the column direction Y of the array. In the first region AA, the boundary line a is located on the side of the first diagonal b facing the first sub-direction Y1, and in the second region AB, the boundary line a is located on the side of the first diagonal b facing the second sub-direction Y2. The first sub-direction Y1 and the second sub-direction Y2 are opposite to each other and both parallel to the column direction of the array.

[0067] Specifically, such as Figure 8As shown, the display panel includes sub-pixels 01, each sub-pixel 01 including first-band color pixels 10. Multiple first-band color pixels 10 are arranged in an array. Each first-band color pixel 10 includes at least two first light-emitting devices 111 and second light-emitting devices 112 emitting the same color light, wherein the first light-emitting devices 111 and second light-emitting devices 112 are arranged along the column direction Y of the array. Furthermore, the display panel includes a first region AA and a second region AB arranged along the column direction Y of the array. The first region AA includes multiple rows of first-band color pixels 10, and the arrangement order of the first light-emitting devices 111 and second light-emitting devices 112 in the first region AA is the same. That is, the boundary line a in the first region AA is located on the side of the first diagonal b facing the first sub-direction Y1, meaning that the first light-emitting device 111 is located above the boundary line a, and the second light-emitting device 112 is located below the boundary line a. The second region AB includes multiple rows of first band color pixels 10. In the second region AB, the arrangement order of the first light-emitting device 111 and the second light-emitting device 112 is the same and the opposite of the arrangement order of the first light-emitting device 111 and the second light-emitting device 112 in the first region AA. That is, the boundary line a in the second region AB is located on the side of the first diagonal line b towards the second sub-direction Y2. In other words, the first light-emitting device 111 in the second region AB is located below the boundary line a, and the second light-emitting device 112 is located above the boundary line a. There are at least two first light-emitting devices 111 and / or at least two second light-emitting devices 112 arranged adjacent to each other, which can make the color shift distribution in each direction more uniform. Furthermore, since when a user views a display panel, their eyes are directly facing the center of the panel, the viewing angles of the two edge areas on the top and bottom sides of the panel are exactly opposite. To address this, by setting the arrangement order of the first light-emitting device 111 and the second light-emitting device 112 in the first area AA to be symmetrical (opposite) to the arrangement order of the first light-emitting device 111 and the second light-emitting device 112 in the second area AB relative to the center of the display panel, the problem of opposite viewing angles in different areas can be improved, thus enhancing the display effect at wide viewing angles.

[0068] Optionally, the first light-emitting device 111 includes any one of OLED, Micro LED, or mini LED, and the second light-emitting device 112 includes any one of OLED, Micro LED, or mini LED. OLED is a device that generates electroluminescence using a multilayer organic thin-film structure. It is easy to manufacture and requires only a low driving voltage, featuring low power consumption, fast response speed, and a wide viewing angle. Micro LED is a device that thins, miniaturizes, and arrays the LED structure, with a size only around 1-10 μm, enabling high-resolution displays. Mini LED (sub-millimeter light-emitting diode) has advantages such as lower power consumption, faster response time, higher resolution and contrast, and longer lifespan, attracting widespread attention in the display technology field and commonly used in light-emitting modules in display devices. Therefore, by setting the first light-emitting device 111 and the second light-emitting device 112 to include any one of OLED, Micro LED, or mini LED, it is beneficial to improve the display effect of the display panel.

[0069] It should be noted that the first light-emitting device 111 and the second light-emitting device 112 can be the same light-emitting device or different light-emitting devices, and the present invention does not limit this.

[0070] Optional, Figure 10 This is a circuit diagram of a pixel circuit provided in an embodiment of the present invention. See also: Figure 10 The display panel also includes a first pixel circuit 30 and a second pixel circuit 40.

The first data writing module 320 and the threshold compensation module 330 are both located on the data signal writing path and are used to write data signals to the input terminal of the first driving module 310 to control the working state of the first driving module 310, thereby controlling the magnitude of the driving current and the light emission brightness of the first light-emitting device 111. The output terminal of the first initialization module 340 is electrically connected to the control terminal of the first driving module 310 and is used to reset the potential of the control terminal of the first driving module 310. The output terminal of the second initialization module 350 is electrically connected to the light-emitting element 111 and is used to reset the anode of the light-emitting element 111 to prevent the light emission of the previous frame from affecting the light emission of the current frame. The first light-emitting control module 360 ​​is connected in series on the light-emitting path, that is, between the first power supply voltage terminal PVDD and the second power supply voltage terminal PVEE. The control terminals of the first light-emitting control module 360 ​​are all electrically connected to the light-emitting control signal output terminal Emit. The light-emitting control signal input to the light-emitting control signal input terminal Emit is used to control the working state of the first light-emitting device 111 during the light-emitting stage.

[0072] The second pixel circuit 40 includes a second driving module 410, a second data writing module 420, a second threshold compensation module 430, a third initialization module 440, a fourth initialization module 450, and a second light emission control module 460. The functions of each module in the second pixel circuit 40 are the same as those in the first pixel circuit 40, and will not be repeated here. Furthermore, by multiplexing the first driving module 310 into the second driving module 410, the first data writing module 320 into the second data writing module 420, the first threshold compensation module 330 into the second threshold compensation module 430, and the first initialization module 340 into the third initialization module 440, the pixel circuit can be simplified, making the circuit control method simpler.

[0073] Optional, see below Figure 10The first driving module 310 includes a first transistor T1, the first light-emitting control module 360 ​​includes a second transistor T2 and a third transistor T3, the second light-emitting control module 460 includes a fourth transistor T4 and a fifth transistor T5, the first initialization module 340 includes a sixth transistor T6, the second initialization module 350 includes a seventh transistor T7, the fourth initialization module 450 includes an eighth transistor T8, the first data writing module 320 includes a ninth transistor T9, and the first threshold compensation module 330 includes a tenth transistor T10. The first terminals of the second transistor T2 and the fourth transistor T4 are both connected to the first power supply voltage terminal PVDD. The second terminals of the second transistor T2 and the fourth transistor T4 are both connected to the first terminal of the first transistor T1. The first terminals of the fourth transistor T4 and the fifth transistor T5 are both connected to the second terminal of the first transistor T1. The control terminals of the second transistor T2 and the third transistor T3 are both connected to the first light-emitting control signal terminal Emit1. The control terminals of the fourth transistor T4 and the fifth transistor T5 are both connected to the second light-emitting control terminal Emit2. The second terminal of the third transistor T3 is connected to the first electrode of the first light-emitting device 111. The second terminal of the fifth transistor T5 is connected to the first electrode of the second light-emitting device 112. The second electrodes of the first light-emitting device 111 and the second electrodes of the second light-emitting device 112 are both connected to the second power supply voltage terminal PVEE. The control terminal of the sixth transistor T6 is connected to the first scan signal terminal Scan1. The first terminal of the sixth transistor T6 is connected to... The reference power signal terminal Vref is connected; the second terminal of the sixth transistor T6 is connected to the control terminal of the first transistor T1; the control terminal of the tenth transistor T10 is connected to the second scan signal terminal Scan2; the first terminal of the tenth transistor T10 is connected to the second terminal of the first transistor T1; the second terminal of the tenth transistor T10 is connected to the control terminal of the first transistor T1; the first terminal of the ninth transistor T9 is connected to the data signal terminal Data; the second terminal of the ninth transistor T9 is connected to the first terminal of the first transistor T1; the control terminal of the ninth transistor T9 is connected to the second scan signal terminal Scan2; the first terminals of the seventh transistor T7 and the eighth transistor T8 are both connected to the reference voltage signal terminal Vref; the second terminal of the seventh transistor T7 is connected to the first electrode of the first light-emitting device 111; the second terminal of the eighth transistor T8 is connected to the first electrode of the second light-emitting device 112; and the control terminals of the seventh transistor T7 and the eighth transistor T8 are both connected to the first scan signal line Scan1.

[0074] Specifically, the scanning signals include a first scanning signal line Scan1 and a second scanning signal line Scan2. The first initialization module 340 includes a sixth transistor T6, and the first driving module 310 includes a first transistor T1. The first terminal of the sixth transistor T6 is connected to the reference power supply signal terminal Vref, and the second terminal of the sixth transistor T6 is connected to the control terminal of the first transistor T1. The control terminal of the sixth transistor T6 is connected to the first scanning signal terminal Scan1. The first data writing module 320 includes a ninth transistor T9, and the control terminal of the ninth transistor T9 is electrically connected to the second scanning signal line Scan2. The operation of the light-emitting circuit 20 also includes an initialization stage and a data writing stage. In the initialization stage, the sixth transistor T6 is turned on, and the control terminal of the first transistor T1 writes the initialization signal. In the data writing stage, the ninth transistor T9 is turned on, and the control terminal of the first transistor T1 writes the data signal. The reset and touch stages reuse the initialization stage and / or the data writing stage.

[0075] Furthermore, the second initialization module 350 includes a seventh transistor T7, and the fourth initialization module 450 includes an eighth transistor T8. The first terminals of both the seventh transistor T7 and the eighth transistor T8 are connected to the reference voltage signal terminal Vref. The second terminal of the seventh transistor T7 is connected to the first electrode of the first light-emitting device 111, and the second terminal of the eighth transistor T8 is connected to the first electrode of the second light-emitting device 112. The control terminals of both the seventh transistor T7 and the eighth transistor T8 are connected to the first scan signal line Scan1. Thus, the first electrodes (anodes) of the first light-emitting device 111 and the second light-emitting device 112 are reset by the seventh transistor T7 and the eighth transistor T8 respectively, so as to avoid the light emission of the previous frame affecting the light emission of the current frame.

[0076] In addition, the first light-emitting control module 360 ​​includes a second transistor T2 and a third transistor T3. The second transistor T2 and the third transistor T3 are disposed on the light-emitting path, that is, the first power supply voltage terminal PVDD and the second power supply voltage terminal PVEE. The first terminal of the second transistor T2 is connected to the first power supply voltage terminal PVDD, the second terminal of the second transistor T2 is connected to the first terminal of the first transistor T1, the first terminal of the third transistor T3 is connected to the second terminal of the first transistor, and the second terminal of the third transistor T3 is connected to the first electrode of the first light-emitting device 111. The control terminals of the second transistor T2 and the third transistor T3 are both connected to the first light-emitting control signal terminal Emit1, thereby controlling the working state of the first light-emitting device 111 during the light-emitting stage through the light-emitting control signal output by the first light-emitting control signal terminal Emit1.

[0077] The second light-emitting control module 460 includes a fourth transistor T4 and a fifth transistor T5. The fourth transistor T4 and the fifth transistor T5 are disposed on the light-emitting path, that is, the first power supply voltage terminal PVDD and the second power supply voltage terminal PVEE. The first terminal of the fourth transistor T4 is connected to the first power supply voltage terminal PVDD, and the second terminal of the fourth transistor T4 is connected to the first terminal of the first transistor T1. The first terminal of the fifth transistor T5 is connected to the second terminal of the first transistor T1, and the second terminal of the fifth transistor T5 is connected to the first electrode of the first light-emitting device 111. The control terminals of the fifth transistor T5 and the fourth transistor T4 are both connected to the second light-emitting control signal terminal Emit2, thereby controlling the working state of the second light-emitting device 112 during the light-emitting stage through the light-emitting control signal output by the second light-emitting control signal terminal Emit2.

[0078] Thus, by setting up independent first pixel circuit 30 and second pixel circuit 40 respectively to control the first light-emitting device 111 and the second light-emitting device 112 to emit light, in the first working mode, the first light-emitting device 111 can be controlled to emit light by the first pixel circuit 30, so that the first sub-band light-emitting color resist 211, which overlaps with the first light-emitting device 111 at least partially, filters the light and transmits the light with a smaller center wavelength in the color light of the first band color emitted by the first light-emitting device 111, that is, transmits the high-frequency blue light in the blue light emitted by the first light-emitting device 111, so as to ensure the display color gamut of the display panel and improve the display effect of the display panel. In the second working state, the second light-emitting device 112 can be controlled to emit light through the second pixel circuit 40, so that the second sub-band light-emitting color filter 212, which overlaps with the second light-emitting device 112 at least partially, filters the light. The light with a larger center wavelength in the color light of the first band color emitted by the second light-emitting device 112 is transmitted, that is, the low-frequency blue light in the blue light emitted by the second light-emitting device 112 is transmitted. The high-frequency blue light is filtered by the second sub-band light-emitting color filter 212, so as to avoid the stimulation of the human eye by the high-frequency blue light and affect the user's sleep. In this way, different working modes can be switched according to different application scenarios, improving the user experience.
