Description

Technical Field

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

[0002] Display devices can be categorized by size into small, medium, and large-size devices, each with different performance requirements. Medium-size displays require a longer lifespan, and designs are often based on this need. However, during use, it has been found that the reflectivity and hue of these displays are poor, resulting in suboptimal performance that fails to meet the requirements.

[0003] Therefore, existing display devices suffer from poor reflectivity and hue. Summary of the Invention

[0004] This application provides a display panel and a display device to improve the technical problem of poor reflectivity and hue in existing display devices.

[0005] To achieve the above objectives, according to a first aspect of this application, a display panel is provided, the display panel including a display area, wherein a first sub-pixel, a second sub-pixel, and a third sub-pixel of different luminous colors are provided in the display area, the opening area of ​​the third sub-pixel is larger than the opening area of ​​the first sub-pixel, and the opening area of ​​the third sub-pixel is larger than the opening area of ​​the second sub-pixel. The display panel further includes invalid sub-pixels disposed within the display area, wherein the emitted light color of the invalid sub-pixels is the same as the emitted light color of at least one of the first sub-pixels and the second sub-pixels.

[0006] According to a second aspect of this application, a display device is provided, the display device including a display panel as described in any of the above embodiments.

[0007] This application provides a display panel and a display device. The display panel has a third sub-pixel with an aperture area larger than that of a first sub-pixel, and the aperture area of ​​the third sub-pixel is larger than that of a second sub-pixel. The display panel also includes a deactivated sub-pixel disposed within the display area. The emitted light color of the deactivated sub-pixel is the same as the emitted light color of at least one of the first and second sub-pixels. By setting a deactivated sub-pixel, the emitted light color of the deactivated sub-pixel is made the same as the emitted light color of at least one of the first and second sub-pixels, thereby reducing the proportion of the emitted light color of the third sub-pixel in the reflected light, adjusting the reflectivity hue of the display panel, improving the reflectivity hue of the display panel, and enhancing the performance of the display panel.

[0008] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0016] To illustrate the principle behind the technical problems in the embodiments of this application, some comparative display devices are provided. It should be understood that these comparative display devices are not considered prior art in the embodiments of this application. Figure 1As shown, the contrast display device includes a red sub-pixel 101, a green sub-pixel 102, and a blue sub-pixel 103. To improve the lifespan of the contrast display device, the aperture area of ​​the blue sub-pixel 103 is made larger than that of the other sub-pixels. However, in actual use, it was found that the reflectance hue (reflectance hue refers to the difference in reflectance of an object to different wavelengths of light, forming a spectrophotometric reflectance curve, where the peak wavelength of the curve corresponds to the hue perceived by the human eye) a* / b* (two axes in the CIE Lab* color space, used to describe the hue and color cast of a color) = 0.03 / -3.34, resulting in poor reflectance hue of the contrast display device, which cannot meet the requirements. Therefore, existing display devices have a technical problem of poor reflectance hue.

[0017] This application provides a display panel and a display device to address the aforementioned technical problems.

[0018] like Figure 2 As shown, this application embodiment provides a display panel 2, which includes a display area 201 and a non-display area 202. The non-display area 202 can be arranged around the display area 201, or it can be arranged on one or more sides of the display area 201. This application embodiment is described with the non-display area 202 surrounding the display area 201 as an example.

[0019] Specifically, the non-display area 202 includes a lower border area 202a, a left border area 202b, a right border area 202c, and a top border area 202d. The lower border area 202a can be used to bond components such as driver chips and flexible circuit boards, and it can also be configured with fan-out traces and bonding terminals to enable the input of external electrical signals and the output of internal electrical signals. One or both of the left border area 202b and the right border area 202c can be configured with gate drive circuits to control the operation of the scan lines, thereby reducing the number of driver chips and lowering costs.

[0020] Specifically, such as Figure 2 As shown, the display area 201 is provided with pixel units, which include a first sub-pixel 301, a second sub-pixel 302, and a third sub-pixel 303 with different light-emitting colors. The light-emitting colors of the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303 are red, green, and blue, respectively. However, the embodiments of this application are not limited to this. For example, the light-emitting colors of the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303 are green, red, and blue, respectively.

[0021] Specifically, such as Figure 2 As shown, the display panel 2 also includes an invalid sub-pixel 41, which is disposed within the display area 201 and is staggered with each sub-pixel.

[0022] Specifically, such as Figure 3 , Figure 4 As shown, the display panel 2 includes a substrate 32, a driving circuit layer 33, a light-emitting functional layer, and an encapsulation layer.

[0023] like Figure 3 , Figure 4 As shown, the display panel 2 may also include a substrate 31. The material of the substrate 31 may be glass, but the embodiments of this application are not limited to this. The display panel 2 may not have a substrate 31, but may only have the substrate 31 during the manufacturing process and peel off the substrate 31 after the manufacturing process is completed.

[0024] Specifically, such as Figure 3 , Figure 4 As shown, the substrate 32 includes a first flexible layer 321, a first barrier layer 322, a second flexible layer 323, and a second barrier layer 324. The first flexible layer 321 and the second flexible layer 323 can be made of polyimide, the first barrier layer 322 can be made of one or a stack of silicon nitride and silicon oxide, and the second barrier layer 324 can be made of one or a stack of silicon nitride and silicon oxide.

[0025] Specifically, Figure 3 , Figure 4 The substrate 32 includes a first flexible layer 321, a first barrier layer 322, a second flexible layer 323, and a second barrier layer 324. However, the embodiments of this application are not limited to this. For example, the substrate 32 may include two flexible layers and one barrier layer.

[0026] Specifically, such as Figure 3 , Figure 4 As shown, the driving circuit layer 33 includes a light-shielding layer 331, a third blocking layer 332, a buffer layer 333, an active layer 334, a first gate insulating layer 335, a first gate layer 336, a second gate insulating layer 337, a second gate layer 338, a first interlayer insulating layer 339, a semiconductor layer 341, a third gate insulating layer 342, a third gate layer 343, a second interlayer insulating layer 344, a first source-drain layer 345, a first planarization layer 346, a second source-drain layer 347, a second planarization layer 348, a third source-drain layer 349, a third planarization layer 351, and a fourth planarization layer 352.

[0027] Specifically, the active layer 334 can be made of silicon semiconductor, specifically low-temperature polycrystalline silicon; the semiconductor layer 341 can be made of oxide semiconductor, specifically indium gallium zinc oxide.

[0028] Specifically, Figure 3 , Figure 4The driving circuit layer 33 is described using an example of an active layer 334 and a semiconductor layer 341. However, the embodiments of this application are not limited to this. The driving circuit layer 33 may include either an active layer 334 or a semiconductor layer 341. Accordingly, the number of gate layers and gate insulating layers can be reduced. For example, when the driving circuit layer 33 includes an active layer 334, a first gate insulating layer 335, a first gate layer 336, a second gate insulating layer 337, and a second gate layer 338 may be provided. There is no need to provide a third gate insulating layer 342 and a third gate layer 343. Correspondingly, only one interlayer insulating layer may be provided.

[0029] Specifically, Figure 3 , Figure 4 The driving circuit layer 33 includes an active layer 334 and a semiconductor layer 341 as an example. The driving circuit layer 33 adopts LTPO (Low Temperature Polycrystalline Oxide) technology. Accordingly, the thin film transistor with the active layer 334 as the active pattern will have a top gate, and the thin film transistor with the semiconductor layer 341 as the active layer pattern will have a top gate and a bottom gate. However, the embodiments of this application are not limited to this. When the driving circuit layer 33 includes one of the active layer 334 and the semiconductor layer 341, one or two gate layers can be provided. The gate layer can be provided on the side of the active layer 334 close to the substrate 32 or on the side of the active layer 334 away from the substrate 32.

[0030] Specifically, Figure 3 , Figure 4 The example given is that the source and drain layers of the driving circuit layer 33 are connected to the active layer by means of top contact and vias. However, the embodiments of this application are not limited to this. The source and drain layers of the driving circuit layer 33 can be connected by means of bottom contact and / or by means of direct overlap between the source and drain layers and the active layer.

[0031] Specifically, Figure 3 , Figure 4 The example given is the driving circuit layer 33, which includes a first source-drain layer 345, a second source-drain layer 347, and a third source-drain layer 349. However, the embodiments of this application are not limited to this. One or two source-drain layers can be provided, and a planarization layer can be provided accordingly.

[0032] Specifically, Figure 3 , Figure 4 The driving circuit layer 33 is described using an example that includes a first planarization layer 346, a second planarization layer 348, a third planarization layer 351, and a fourth planarization layer 352. However, the embodiments of this application are not limited to this, and the driving circuit layer 33 may include three planarization layers.

[0033] Specifically, such as Figure 3 , Figure 4 As shown, the light-emitting functional layer includes a pixel electrode layer 361, a pixel definition layer 362, a light-emitting material layer 363, a support pillar 364, and a common electrode layer 365.

[0034] like Figure 3 , Figure 4 As shown, the pixel definition layer 362 includes a transparent definition layer 372 and a black definition layer 371. The black definition layer 371 is disposed between the transparent definition layer 372 and the driving circuit layer 33. The transmittance of the black definition layer 371 is less than that of the transparent definition layer 372, which reduces the reflection of the black definition layer 371 and allows the transparent definition layer 372 to transmit light.

[0035] Specifically, Figure 3 , Figure 4 The pixel definition layer 362 includes a black definition layer 371 and a transparent definition layer 372 as an example for illustration, but the embodiments of this application are not limited to this. The pixel definition layer 362 can be formed of a single material, such as a light-transmitting material.

[0036] Specifically, the encapsulation layer includes a first inorganic layer, an organic layer, and a second inorganic layer.

[0037] like Figures 2 to 4 As shown, this application embodiment provides a display panel 2 including a display area 201. The display area 201 is provided with a first sub-pixel 301, a second sub-pixel 302, and a third sub-pixel 303 with different light emission colors. The opening area of ​​the third sub-pixel 303 is larger than the opening area of ​​the first sub-pixel 301, and the opening area of ​​the third sub-pixel 303 is larger than the opening area of ​​the second sub-pixel 302. The display panel 2 further includes an invalid sub-pixel 41 disposed within the display area 201, wherein the emitted light color of the invalid sub-pixel 41 is the same as the emitted light color of at least one of the first sub-pixel 301 and the second sub-pixel 302.

[0038] This application provides a display panel 2. The opening area of ​​the third sub-pixel 303 in the display panel 2 is larger than the opening area of ​​the first sub-pixel 301, and the opening area of ​​the third sub-pixel 303 is larger than the opening area of ​​the second sub-pixel 302. The display panel 2 also includes an invalid sub-pixel 41 disposed within the display area 201. The emitted light color of the invalid sub-pixel 41 is the same as the emitted light color of at least one of the first sub-pixel 301 and the second sub-pixel 302. By setting an invalid sub-pixel, the emitted light color of the invalid sub-pixel 41 is made the same as the emitted light color of at least one of the first sub-pixel 301 and the second sub-pixel 302, thereby reducing the proportion of the emitted light color of the third sub-pixel in the reflected light, adjusting the reflectivity hue of the display panel, improving the reflectivity hue of the display panel, and enhancing the performance of the display panel.

[0039] Specifically, in contrast display devices, due to the larger aperture area of ​​the blue sub-pixel, the reflectivity hue of the contrast display device tends to be bluish when the screen is off, resulting in poor reflectivity hue. Based on the problem of the bluish reflectivity hue of the contrast display device, this application embodiment makes the aperture area of ​​the third sub-pixel 303 larger than the aperture area of ​​the first sub-pixel 301, and the aperture area of ​​the third sub-pixel 303 larger than the aperture area of ​​the second sub-pixel 302. An invalid sub-pixel 41 is added so that the invalid sub-pixel 41 does not emit light in the normal display state, does not affect the normal display of the display panel, and can still improve the lifespan of the display panel and the normal display effect of the display panel. Furthermore, when the display panel is in the off state, the invalid sub-pixel 41 can also reflect light. Since the emission color of the invalid sub-pixel 41 is the same as the emission color of at least one of the first sub-pixel 301 and the second sub-pixel 302, the proportion of green and / or red light in the reflected light is increased, which reduces the proportion of blue light in the reflected light. This adjusts the reflectivity hue of the display panel, thereby preventing the reflectivity hue of the display panel from being too blue and improving the reflectivity hue of the display panel.

[0040] Specifically, the emitted light color of the invalid sub-pixel 41 refers to the color of the light emitted from the invalid sub-pixel 41. It can be understood that when the invalid sub-pixel 41 emits light, its emitted light color is the same as its emitted light color; when the invalid sub-pixel 41 does not emit light, its emitted light color refers to the color of the light reflected by the invalid sub-pixel 41. The emitted light color of the invalid sub-pixel 41 refers to the color when it emits light. Although the invalid sub-pixel 41 in this embodiment does not emit light, it can be provided with a light-emitting material and corresponding electrodes. Its emitted light color can be determined by the light-emitting material of the invalid sub-pixel 41. For example, if the emitted light color of the invalid sub-pixel 41 is green, then the invalid sub-pixel 41 will use the same light-emitting material as the green sub-pixel, so that the invalid sub-pixel 41 emits green light when it is capable of emitting light.

[0041] Specifically, the fact that the emitted light color of invalid sub-pixel 41 is the same as the emitted light color of at least one of the first sub-pixel 301 and the second sub-pixel 302 means that: when invalid sub-pixel 41 has one emitted light color, the emitted light color of invalid sub-pixel 41 is the same as the emitted light color of one of the first sub-pixel 301 and the second sub-pixel 302; when invalid sub-pixel 41 has two different emitted light colors, some invalid sub-pixels 41 have the same emitted light color as the emitted light color of the first sub-pixel 301, and some invalid sub-pixels 41 have the same emitted light color as the emitted light color of the second sub-pixel 302.

[0042] In some embodiments, the emitted light color of the invalid sub-pixel 41 is the same as the emitted light color of the first sub-pixel 301, thereby reducing the proportion of blue light in the reflected light, adjusting the reflectivity hue of the display panel, thereby avoiding a bluish reflectivity hue in the display panel and improving the reflectivity hue of the display panel.

[0043] In some embodiments, the light emitted by the invalid sub-pixel 41 is the same as the light emitted by the second sub-pixel 302; thereby reducing the proportion of blue light in the reflected light, adjusting the reflectivity hue of the display panel, thereby avoiding a bluish reflectivity hue in the display panel, and improving the reflectivity hue of the display panel.

[0044] In some embodiments, such as Figure 2 As shown, the invalid sub-pixel 41 includes a first virtual sub-pixel 401 and a second virtual sub-pixel 402. The emitted light color of the first virtual sub-pixel 401 is the same as the emitted light color of the first sub-pixel 301, and the emitted light color of the second virtual sub-pixel 402 is the same as the emitted light color of the second sub-pixel 302. By including the first virtual sub-pixel 401 and the second virtual sub-pixel 402 in the invalid sub-pixel 41, and making the emitted light color of the first virtual sub-pixel 401 the same as the emitted light color of the first sub-pixel 301, and the emitted light color of the second virtual sub-pixel 402 the same as the emitted light color of the second sub-pixel 302, the proportion of the emitted light color of the first sub-pixel 301 and the emitted light color of the second sub-pixel 302 during the reflection process of the display panel can be increased, the proportion of each color in the display panel can be balanced, and the reflectivity and hue of the display panel can be further improved.

[0045] Specifically, such as Figure 2As shown, the display panel 2 has a first sub-pixel 301, a second sub-pixel 302, and a third sub-pixel 303. Although the opening area of ​​the first sub-pixel 301 is larger than that of the second sub-pixel 302, and the opening area of ​​the first sub-pixel 301 is larger than that of the third sub-pixel 303, in this embodiment, by setting the first virtual sub-pixel 401 and the second virtual sub-pixel 402, the proportion of the luminous color of the first sub-pixel 301 in the reflectivity hue is increased, and the proportion of the luminous color of the second sub-pixel 302 in the reflectivity hue is also increased. This makes the light reflected by the display panel in the screen-off state more balanced, balances the proportion of each color in the display panel, and further improves the reflectivity hue of the display panel.

[0046] In some embodiments, such as Figure 3 , Figure 4 As shown, the display panel includes a substrate 32, a driving circuit layer 33, and a pixel electrode layer 361. The driving circuit layer 33 is disposed on one side of the substrate 32 and includes a first pixel circuit (not shown) and a second pixel circuit (not shown). The pixel electrode layer 361 is disposed on the side of the driving circuit layer 33 away from the substrate 32 and includes a first pixel electrode 361a and a second pixel electrode 361b. The first pixel electrode 361a is correspondingly disposed with the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303, and the second pixel electrode 361b is correspondingly disposed with the invalid sub-pixel 41. The first pixel electrode 361a is electrically connected to the first pixel circuit, while the second pixel electrode 361b is insulated from the second pixel circuit. By electrically connecting the first pixel electrode 361a to the first pixel circuit and insulating the second pixel electrode 361b from the second pixel circuit, the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303 can be displayed normally under the drive of the first pixel circuit. The insulated connection of the second pixel electrode 361b from the second pixel circuit prevents the invalid sub-pixel 41 from being displayed, thus avoiding interference with the normal display process. Furthermore, the invalid sub-pixel 41 can reflect light in the screen-off state, improving the reflectivity and hue of the display panel.

[0047] Specifically, the first pixel electrode 361a may include a first sub-electrode, a second sub-electrode, and a third sub-electrode corresponding to the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303, respectively. The first pixel circuit may include a first driving circuit, a second driving circuit, and a third driving circuit. The first sub-electrode, the second sub-electrode, and the third sub-electrode are electrically connected to the first driving circuit, the second driving circuit, and the third driving circuit, respectively, to realize independent control of each sub-pixel.

[0048] Specifically, when the invalid sub-pixel 41 includes a first virtual sub-pixel 401 and a second virtual sub-pixel 402, the second pixel electrode 361b may include a first virtual pixel electrode and a second virtual pixel electrode, and the second pixel circuit includes a first virtual driving circuit and a second virtual driving circuit. The first virtual pixel electrode and the second virtual pixel electrode are respectively configured to correspond to the first virtual sub-pixel 401 and the second virtual sub-pixel 402. The first virtual pixel electrode is insulated from the first virtual driving circuit, and the second virtual pixel electrode is insulated from the second virtual driving circuit.

[0049] Specifically, the second pixel circuit can be omitted, thus saving space.

[0050] In some embodiments, such as Figure 3 , Figure 4 As shown, the display panel 2 includes a substrate 32 and a pixel definition layer 362. The pixel definition layer 362 is disposed on one side of the substrate 32. The pixel definition layer 362 has openings in the areas corresponding to the first sub-pixel 301, the second sub-pixel 302, the third sub-pixel 303 and the invalid sub-pixel 41. By providing openings in the areas corresponding to the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303 in the pixel definition layer 362, the light-emitting materials corresponding to the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303 can be placed within the openings, enabling the display panel to display normally. Furthermore, by providing openings in the area corresponding to the invalid sub-pixel 41 in the pixel definition layer 362, the light-emitting material corresponding to the invalid sub-pixel 41 can be placed within the openings, making the light-emitting structure of the invalid sub-pixel 41 the same as that of the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303. This facilitates the adjustment of the reflected hue of each sub-pixel, resulting in a more balanced distribution of light of various colors reflected by the display panel in the off-screen state, balancing the proportion of each color in the display panel, and further improving the reflectivity and hue of the display panel.

[0051] Specifically, when invalid sub-pixels 41 include first virtual sub-pixels 401 and second virtual sub-pixels 402, the pixel definition layer 362 can provide openings in the areas corresponding to the first virtual sub-pixels 401 and second virtual sub-pixels 402, so that the light-emitting materials corresponding to the first virtual sub-pixels 401 and second virtual sub-pixels 402 can be placed in the openings, so that the reflection effect of the first virtual sub-pixels 401 and second virtual sub-pixels 402 is similar to or even the same as the reflection effect of the first sub-pixels 301 and second sub-pixels 302, which facilitates the control of the reflection effect of sub-pixels of each color, so that the light of each color reflected by the display panel in the screen-off state is more balanced, the proportion of each color in the display panel is balanced, and the reflectivity and hue of the display panel are further improved.

[0052] Specifically, such as Figure 3 As shown, when the pixel definition layer 362 includes a transparent definition layer 372 and a black definition layer 371, the transparent definition layer 372 can have openings in the areas corresponding to the first sub-pixel 301, the second sub-pixel 302, the third sub-pixel 303 and the invalid sub-pixel 41, and the black definition layer 371 can have openings in the areas corresponding to the first sub-pixel 301, the second sub-pixel 302, the third sub-pixel 303 and the invalid sub-pixel 41.

[0053] In some embodiments, the display panel further includes a pixel electrode layer 361 disposed between the substrate 32 and the pixel definition layer 362. The pixel electrode layer 361 includes a first pixel electrode 361a and a second pixel electrode 361b. The first pixel electrode 361a is correspondingly disposed with the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303. The second pixel electrode 361b is correspondingly disposed with the invalid sub-pixel 41. The second pixel electrode 361b is suspended. By suspending the second pixel electrode 361b, the second pixel electrode 361b can release its charge, preventing the invalid sub-pixel from shining brightly and affecting the display effect.

[0054] Specifically, when invalid sub-pixel 41 includes a first virtual sub-pixel 401 and a second virtual sub-pixel 402, the second pixel electrode 361b includes a first virtual pixel electrode and a second virtual pixel electrode. This allows both the first virtual pixel electrode and the second virtual pixel electrode to be suspended, thereby releasing charge through the first virtual pixel electrode and the second virtual pixel electrode, preventing the first virtual sub-pixel 401 and the second virtual sub-pixel 402 from shining too brightly and affecting the display effect.

[0055] In some embodiments, the display panel further includes a pixel electrode layer 361 disposed between the substrate 32 and the pixel definition layer 362. The pixel electrode layer 361 includes a first pixel electrode 361a and a second pixel electrode 361b. The first pixel electrode 361a is correspondingly disposed with the first sub-pixel 301, the second sub-pixel 302 and the third sub-pixel 303, and the second pixel electrode 361b is correspondingly disposed with the invalid sub-pixel 41. The display panel 2 further includes a fixed potential line, and the second pixel electrode 361b is connected to the fixed potential line. By connecting the second pixel electrode 361b to the fixed potential line, the potential of the second pixel electrode 361b is stabilized, preventing the invalid sub-pixel from shining and affecting the display effect.

[0056] Specifically, the fixed potential line can be set in the third source-drain layer, but the embodiments of this application are not limited to this. Depending on the potential required to be input by the fixed potential line, the fixed potential line can be formed by one or more layers of metal.

[0057] Specifically, a negative potential signal or a common electrode layer signal can be input on the fixed potential line, so that the light-emitting material layer between the second pixel electrode 361b and the common electrode layer will not emit light, thus preventing invalid sub-pixels from shining and affecting the display effect.

[0058] Specifically, when invalid sub-pixel 41 includes a first virtual sub-pixel 401 and a second virtual sub-pixel 402, the second pixel electrode 361b includes a first virtual pixel electrode and a second virtual pixel electrode. Multiple fixed potential lines can be set so that the first virtual pixel electrode and the second virtual pixel electrode are respectively connected to the corresponding fixed potential lines. This can stabilize the potential of the first virtual pixel electrode and the second virtual pixel electrode and prevent the first virtual sub-pixel 401 and the second virtual pixel 402 from shining too brightly and affecting the display effect.

[0059] In some embodiments, such as Figure 4 As shown, the display panel 2 further includes a substrate 32 and a pixel definition layer 362. The pixel definition layer 362 is disposed on one side of the substrate 32. The pixel definition layer 362 includes a transparent definition layer 372 and a black definition layer 371. The black definition layer 371 is disposed between the substrate 32 and the transparent definition layer 372. The black definition layer 371 has a first opening 371a in the area corresponding to the first sub-pixel 301, the second sub-pixel 302, the third sub-pixel 303, and the invalid sub-pixel 41. The transparent definition layer 372 has a second opening 371b in the area corresponding to the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303. The transparent definition layer 372 is disposed within the first opening 371a in the area corresponding to the invalid sub-pixel 41. By setting the transparent definition layer 372 within the first opening 371a in the area corresponding to the invalid sub-pixel 41, the transparent definition layer 372 can block the charge. Even if charge accumulates, it will not cause the invalid sub-pixel 41 to shine, thus avoiding the invalid sub-pixel from shining and affecting the display effect.

[0060] Specifically, such as Figure 4 As shown, the black definition layer 371 has a first opening 371a in the area corresponding to the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303, and the transparent definition layer 372 has a second opening 371b in the area corresponding to the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303, so that the light-emitting materials corresponding to the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303 can be respectively set in the corresponding pixel openings, so as to realize the normal display of the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303.

[0061] Specifically, it can be understood that the areas of the first opening 371a corresponding to the first sub-pixel 301, the first opening 371a corresponding to the second sub-pixel 302, and the first opening 371a corresponding to the third sub-pixel 303 can be different. The areas of the second opening 371b corresponding to the first sub-pixel 301, the second opening 371b corresponding to the second sub-pixel 302, and the second opening 371b corresponding to the third sub-pixel 303 can also be different.

[0062] Specifically, such as Figure 4 As shown, the black definition layer 371 also has a first opening 371a in the area corresponding to the invalid sub-pixel 41, but the transparent definition layer 372 does not have an opening in the area corresponding to the invalid sub-pixel 41. Instead, it is set inside the first opening 371a, so that the second pixel electrode 361b corresponding to the invalid sub-pixel 41 is provided with a transparent definition layer 372 between it and the light-emitting material. This can block charge transmission, prevent the invalid sub-pixel 41 from stealing light, and prevent the invalid sub-pixel from stealing light and affecting the display effect.

[0063] Specifically, when the invalid sub-pixel 41 includes a first virtual sub-pixel 401 and a second virtual sub-pixel 402, the black definition layer 371 has a first opening 371a in the area corresponding to the first virtual sub-pixel 401 and the second virtual sub-pixel 402, and the transparent definition layer 372 does not have an opening in the area corresponding to the first virtual sub-pixel 401 and the second virtual sub-pixel 402, but is disposed in the first opening 371a. This makes it possible to have a transparent definition layer 372 between the second pixel electrode 361b corresponding to the first virtual sub-pixel 401 and the second virtual sub-pixel 402 and the light-emitting material, thereby blocking charge transmission and preventing the first virtual sub-pixel 401 and the second virtual sub-pixel 402 from stealing light, and preventing the invalid sub-pixel from stealing light and affecting the display effect.

[0064] Specifically, the above embodiment uses the example of a black definition layer being disposed between the pixel electrode layer and the transparent definition layer for illustration. However, the embodiments of this application are not limited to this, and the transparent definition layer can be disposed between the pixel electrode layer and the black definition layer. Furthermore, the transparent definition layer 372 can have a second opening 371b in the region corresponding to the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303, and the black definition layer 371 can have a first opening 371a in the regions corresponding to the first sub-pixel 301, the second sub-pixel 302, the third sub-pixel 303, and the invalid sub-pixel 41.

[0065] In some embodiments, such as Figure 3 , Figure 4As shown, the display panel 2 further includes a light-emitting material layer 363 and a common electrode layer 365, which are disposed in the setting area of ​​the invalid sub-pixel 41. This allows the invalid sub-pixel 41 to have a complete structure, thereby having the same reflective effect as the normal sub-pixel, adjusting the reflectivity hue of the display panel, thus avoiding a bluish reflectivity hue and improving the reflectivity hue of the display panel.

[0066] Specifically, such as Figure 3 , Figure 4 As shown, the light-emitting material layer 363 and the common electrode layer 365 are disposed in the setting areas of the first sub-pixel 301, the second sub-pixel 302 and the third sub-pixel 303 to realize the normal display of each sub-pixel. The light-emitting material layer 363 may include a first light-emitting part, a second light-emitting part and a third light-emitting part corresponding to the first sub-pixel 301, the second sub-pixel 302 and the third sub-pixel 303 respectively.

[0067] Specifically, such as Figure 3 , Figure 4 As shown, the light-emitting material layer 363 also includes an invalid light-emitting portion corresponding to the invalid sub-pixel 41. When the invalid sub-pixel 41 includes a first virtual sub-pixel 401 and a second virtual sub-pixel 402, the light-emitting material layer 363 includes a first virtual light-emitting portion and a second virtual light-emitting portion corresponding to the first virtual sub-pixel 401 and the second virtual sub-pixel 402, respectively. Furthermore, when the transparent definition layer has an opening in the area corresponding to the first virtual sub-pixel 401 and the second virtual sub-pixel 402, the first virtual light-emitting portion and the second virtual light-emitting portion are disposed within the opening of the transparent definition layer. When the transparent definition layer does not have an opening in the area corresponding to the first virtual sub-pixel 401 and the second virtual sub-pixel 402, the first virtual light-emitting portion and the second virtual light-emitting portion are disposed on the transparent definition layer.

[0068] In some embodiments, the display panel 2 further includes a light-emitting material layer 363, which is disposed in the area where the first sub-pixel 301, the second sub-pixel 302, and the third sub-pixel 303 are disposed, and the light-emitting material layer 363 has an opening in the area corresponding to the invalid sub-pixel 41.

[0069] Specifically, when setting invalid sub-pixels 41, the light-emitting material layer 363 can be omitted in the area of ​​invalid sub-pixels 41, and light reflection can be achieved by setting pixel electrodes and color resists.

[0070] Specifically, a common electrode layer can be set in the area corresponding to invalid sub-pixel 41, or no common electrode layer can be set.

[0071] In some embodiments, such as Figure 2As shown, the first sub-pixel 301 and the second sub-pixel 302 are staggered in the same row, and the first sub-pixel 301 and the third sub-pixel 303 are staggered in the same column. The invalid sub-pixel 41 is set in the same column as the second sub-pixel 302, and the invalid sub-pixel 41 is set in the same row as the third sub-pixel 303. This allows the invalid sub-pixel 41 to utilize the space between each sub-pixel, avoiding the occupation of extra space and improving the resolution of the display panel.

[0072] Specifically, it can be seen that the spacing between the center line of the third sub-pixel 303 in different columns and the center line of the first sub-pixel 301 in the corresponding column is different. This is because the setting position of the third sub-pixel 303 can fluctuate within a certain range, thereby adjusting the spacing between each sub-pixel and the display effect. However, the embodiments of this application are not limited to this. The spacing between the center line of the third sub-pixel 303 in different columns and the center line of the first sub-pixel 301 in the corresponding column can be the same, or even the center lines of the third sub-pixel 303 in each column can overlap with the center lines of the first sub-pixel 301 in the corresponding column.

[0073] Specifically, the area of ​​the first virtual sub-pixel 401 can be smaller than the area of ​​the first sub-pixel 301, and the area of ​​the second virtual sub-pixel 402 can be smaller than the area of ​​the second sub-pixel 302.

[0074] Specifically, the sum of the areas of the first virtual sub-pixel 401 and the first sub-pixel 301 can be greater than or equal to the area of ​​the third sub-pixel 303. The sum of the areas of the second virtual sub-pixel 402 and the second sub-pixel 302 can be greater than or equal to the area of ​​the third sub-pixel 303.

[0075] In some embodiments, the display panel further includes a color resist layer and a black matrix layer. The black matrix layer is disposed on the side of the encapsulation layer away from the substrate. The black matrix layer has openings in the regions corresponding to the first sub-pixel, the second sub-pixel, the third sub-pixel, and the invalid sub-pixel. The color resist layer is disposed in the openings of the black matrix layer. The color resist layer includes a first color resist, a second color resist, a third color resist, and an invalid color resist, respectively corresponding to the first sub-pixel, the second sub-pixel, the third sub-pixel, and the invalid sub-pixel.

[0076] Specifically, the light-transmitting colors of the first color resist, the second color resist, and the third color resist are red, green, and blue, respectively, or the light-transmitting colors of the first color resist, the second color resist, and the third color resist are red, green, and blue, respectively; the light-transmitting colors of the first color resist, the second color resist, and the third color resist are the same as the light-emitting colors of the first sub-pixel, the second sub-pixel, and the third sub-pixel, respectively.

[0077] Specifically, the light-transmitting color of the invalid color resist is the same as the light-transmitting color of at least one of the first and second color resists; the light-transmitting color of the invalid color resist is the same as the light-emitting color of the invalid sub-pixel.

[0078] Specifically, invalid color resists can include a first invalid color resist and a second invalid color resist. The light transmission color of the first invalid color resist can be the same as the light transmission color of the first color resist, and the light transmission color of the second invalid color resist can be the same as the light transmission color of the second color resist.

[0079] Specifically, by setting an invalid color resist, the light-transmitting color of the invalid color resist is the same as the light-emitting color of at least one of the first and second sub-pixels. This allows the light reflected by the pixel electrode to have color, thereby increasing the proportion of the light-emitting color of at least one of the first and second sub-pixels in the reflected light, reducing the proportion of the light-emitting color of the third sub-pixel in the reflected light, adjusting the reflectivity hue of the display panel, improving the reflectivity hue of the display panel, and enhancing the performance of the display panel.

[0080] Specifically, it can be understood that invalid color resists can be formed simultaneously with the first and second color resists without requiring a separate process. For example, when the light transmission color of the invalid color resist is the same as that of the first color resist, the invalid color resist and the first color resist can be formed simultaneously. When the light transmission color of the invalid color resist is the same as that of the second color resist, the invalid color resist and the second color resist can be formed simultaneously. When invalid color resists include both the first and second invalid color resists, and the light transmission color of the first invalid color resist is the same as that of the first color resist, and the light transmission color of the second invalid color resist is the same as that of the second color resist, the first and second invalid color resists can be formed simultaneously with the first and second color resists, respectively.

It is understood that when there is no conflict between the embodiments, the embodiments can be combined. For example, the transparent definition layer has a second opening in the area corresponding to the first sub-pixel, the second sub-pixel, and the third sub-pixel, the transparent definition layer is disposed in the first opening in the area corresponding to the invalid sub-pixel, and the second pixel electrode is suspended.
