Description

Technical Field

[0001] The present application relates to the field of display technology, and more specifically, to a display panel, a method for manufacturing a display panel, and an electronic device. Background Art

[0002] Organic Light Emitting Diode (OLED) and flat-panel display devices based on technologies such as Light Emitting Diode (LED) have been widely used in various consumer electronic products such as mobile phones, televisions, laptops, desktop computers, etc. due to their advantages of high image quality, power saving, thin body and wide range of applications, becoming the mainstream in display panels. In the traditional display panel preparation process, fine metal masks (FMM) are usually used to achieve the graphicization of luminous pixels. FMM technology is mature and has rich experience in mass production. However, FMM technology also has problems such as limited precision, high development cost and long development cycle. The non-fine metal mask technology eliminates the limitations of traditional OLED processes on display size, resolution and other screen performance, and has the advantages of high performance, full-area size and agile delivery.

DETAILED DESCRIPTION

[0178] It should be noted that, in the absence of conflict, different features in the embodiments of the present application can be combined with each other.

[0179] Increasing the density of light-emitting units (i.e., pixel density) in display panels is an important approach to improving display quality. However, current display panels manufactured using fine metal evaporation mask (FMM) technology are currently unable to further increase the density of light-emitting units due to technical limitations. The inventors have discovered, through long-term research, that to address the technical issue of the inability to further increase the density of light-emitting units, an isolation structure is provided in some display panels. During the full-layer evaporation of the light-emitting functional layer and the second electrode, the light-emitting functional layer and the second electrode can be disconnected at the isolation structure. Through multiple evaporation and etching processes (i.e., light-emitting unit patterning), light-emitting units of different colors can be formed in different isolation openings.

[0180] The display panel in the related technology includes a first display area and a second display area surrounding at least part of the first display area. The display panel includes a substrate and an isolation structure located on one side of the substrate. The isolation structure encloses multiple isolation openings and multiple light-transmitting openings. The multiple light-transmitting openings are located in the first display area.

[0181] A photosensitive device is set under the screen of the first display area, and external light reaches the photosensitive device through the light-transmitting opening to realize the relevant functions of the photosensitive device, such as a camera receives external light to realize the camera function.

[0182] However, for a transparent screen, only providing a light-transmitting opening in the first display area in the related art cannot meet the light-transmitting requirement of the transparent screen, thereby affecting the performance of the transparent display panel.

[0183] In order to solve the above-mentioned technical problems, the inventors have innovatively designed the following technical solutions, and the specific implementation solutions of this application will be described in detail below with reference to the accompanying drawings. It should be noted that the defects existing in the solutions in the above-mentioned prior art are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above-mentioned technical problems and the solutions proposed in this embodiment below for the above-mentioned problems should all be the contributions made by the inventors to this application in the process of invention and creation, and should not be understood as technical contents known to those skilled in the art.

[0184] See Figure 1-Figure 3 This embodiment provides a display panel, which includes a first display area AA1 and a second display area AA2 surrounding at least a portion of the first display area AA1. The display panel includes a substrate 1, an isolation structure 6 and a light-emitting unit 9.

[0185] The substrate 1 may include a substrate, and the display panel may further include multiple driving units located on one side of the substrate; alternatively, the substrate 1 may include a substrate and multiple driving units located on one side of the substrate. Each driving unit may include one or more semiconductor switching devices, which may be formed by the cooperation of multiple film layers in the substrate 1. For example, the semiconductor switching device may be a thin film transistor formed by the cooperation of multiple film layers.

[0186] The isolation structure 6 is located on one side of the substrate 1. The isolation structure 6 encloses a plurality of isolation openings 7 and a plurality of light-transmitting openings. The plurality of isolation openings 7 are located in the first display area AA1 and the second display area AA2. The plurality of light-transmitting openings include a plurality of first light-transmitting sub-openings 8. The plurality of first light-transmitting sub-openings 8 are located in the second display area AA2.

[0187] At least a portion of the light emitting unit 9 is located in the isolation opening 7 .

[0188] A photosensitive device is provided under the screen of the first display area AA1, and multiple isolation openings 7 are located in the first display area AA1 and the second display area AA2. At least part of the light-emitting unit 9 is provided in the isolation opening 7. That is, the first display area AA1 of the display panel can not only display normally, but also realize the remaining functions of the display panel through the photosensitive device provided in the first display area AA1. The second display area AA2 mainly plays a display role. Usually, the area of the second display area AA2 is larger than that of the first display area AA1.

[0189] In this embodiment, a first light-transmitting sub-opening 8 is provided in the second display area AA2, which can reduce the amount of external light blocked by the isolation structure 6 located in the second display area AA2. External light can pass through the first light-transmitting sub-opening 8, thereby improving the transmittance of the display panel and meeting the transparency requirements of the transparent screen.

[0190] Based on the above design, this embodiment sets a first light-transmitting sub-opening 8 in the second display area AA2, which can reduce the amount of external light blocked by the isolation structure 6 located in the second display area AA2, thereby improving the transmittance of the display panel and further improving the performance of the display panel.

[0191] For some possible implementations, see again Figure 3 The light-emitting unit 9 includes a first electrode 2, a light-emitting functional portion 3, and a second electrode 4 stacked in sequence in a direction away from the substrate 1. The display panel also includes a pixel defining layer 5 located between the substrate 1 and the isolation structure 6. The pixel defining layer 5 defines a plurality of pixel openings 51. The pixel openings 51 are connected to the corresponding isolation openings 7. The orthographic projection of the pixel opening 51 on the substrate 1 is located within the orthographic projection of the isolation opening 7 on the substrate 1. The orthographic projection of the pixel opening 51 on the substrate 1 is smaller than the orthographic projection area of the isolation opening 7 on the substrate 1.

[0192] The provision of the isolation structure 6 enables the display panel to form film layers of light-emitting units 9 of different colors in different isolation openings 7 without the need for a fine mask. When forming the light-emitting material layer, the light-emitting material layer is separated by the isolation structure 6 to form a plurality of spaced light-emitting functional units 3. When forming the second electrode material layer, the second electrode material layer is separated by the isolation structure 6 to form a plurality of spaced second electrodes 4. The isolation structure 6 comprises a conductive material, and the second electrodes 4 are electrically connected to the isolation structure 6. One first electrode 2, one light-emitting functional unit 3, and one second electrode 4 form one light-emitting unit 9. The first electrode 2 can be an anode, and the second electrode 4 can be a cathode.

[0193] In this way, different light-emitting units 9 can be made independent of each other, thereby reducing crosstalk between adjacent light-emitting units 9 and improving the display effect of the display panel. At the same time, due to the presence of the isolation structure 6, the light-emitting material layer and the second electrode material layer in the light-emitting unit 9 of each color in the display panel can be first prepared on the entire surface and then patterned, thereby eliminating the need for a fine mask and further reducing the production cost of the display panel.

[0194] For some possible implementations, see again Figure 1 The second display area AA2 includes a first area AA21 and a second area AA22 , and the density of the first light-transmitting sub-openings 8 located in the first area AA21 is greater than the density of the first light-transmitting sub-openings 8 located in the second area AA22 .

[0195] According to different actual light transmittance requirements, the setting density of the first light-transmitting sub-openings 8 at different positions of the second display area AA2 can be different. For example, the second display area AA2 includes the first area AA21 and the second area AA22. The light transmittance requirement of the first area AA21 is greater than the light transmittance requirement of the second area AA22. Then the density of the first light-transmitting sub-openings 8 located in the first area AA21 can be set to be greater than the density of the first light-transmitting sub-openings 8 located in the second area AA22. In this way, the different light transmittance requirements of the second display area AA2 of the display panel can be better met, thereby further improving the display performance of the display panel.

[0196] For some possible implementations, see Figure 4 The plurality of light-transmitting openings further include a plurality of second light-transmitting sub-openings 10 , and the plurality of second light-transmitting sub-openings 10 are located in the first display area AA1 .

[0197] External light reaches the photosensitive device through the second light-transmitting sub-opening 10 to realize the relevant functions of the photosensitive device. For example, the camera receives external light to realize the camera function.

[0198] The second light-transmitting sub-openings 10 located in the first display area AA1 and the first light-transmitting sub-openings 8 located in the second display area AA2 may have the same shape, size, density, etc., or may be different.

[0199] For some possible implementations, see Figure 5 The display panel further includes a filling layer, which includes a plurality of filling portions 11 arranged at intervals, at least part of the filling portion 11 is located in the light-transmitting opening, and the filling portion 11 covers at least part of the side wall of the isolation structure 6 facing the light-transmitting opening.

[0200] In related art, during the process of patterning the light-emitting unit 9, the side wall of the isolation structure 6 toward the light-transmitting opening may be further etched, which may eventually affect the transmission of the second electrode 4 signal, thereby affecting the normal display of the corresponding light-emitting unit 9, or even causing the corresponding light-emitting unit 9 to fail.

[0201] In this embodiment, before patterning the light-emitting unit 9, a filling portion 11 is first set in the light-transmitting opening, and the filling portion 11 covers at least part of the side wall of the isolation structure 6 facing the light-transmitting opening. During the process of patterning the light-emitting unit 9, the filling portion 11 can protect the side wall of the isolation structure 6 facing the light-transmitting opening, so that it is not easy to damage the side wall of the isolation structure 6 facing the light-transmitting opening, and thus it is not easy to cause the corresponding light-emitting unit 9 to fail, thereby improving the display effect of the display panel.

[0202] Preferably, the filling portion 11 covers the side wall of the isolation structure 6 facing the light-transmitting opening. In this way, the filling portion 11 completely covers the side wall of the isolation structure 6 facing the light-transmitting opening, thereby improving the protection effect of the filling portion 11 on the side wall of the isolation structure 6 facing the light-transmitting opening.

[0203] In one embodiment, see Figure 5 and Figure 6 , the distance between the side of the filling portion 11 away from the substrate 1 and the substrate 1 is greater than or equal to the distance between the side of the isolation structure 6 away from the substrate 1 and the substrate 1 .

[0204] for example, Figure 5 The distance between the side of the middle filling portion 11 away from the substrate 1 and the substrate 1 is greater than the distance between the side of the isolation structure 6 away from the substrate 1 and the substrate 1; Figure 6 The distance from the side of the middle filling portion 11 away from the substrate 1 to the substrate 1 is equal to the distance from the side of the isolation structure 6 away from the substrate 1 to the substrate 1; the filling portion 11 is a whole layer, the filling portion 11 completely fills the light-transmitting opening, and the filling portion 11 can completely cover the side wall of the isolation structure 6 facing the light-transmitting opening.

[0205] Optionally, the side of the filling portion 11 away from the substrate 1 includes a first plane parallel to the substrate 1. In this way, the filling portion 11 just fills the light-transmitting opening, which not only allows the filling portion 11 to completely protect the side wall of the isolation structure 6 facing the light-transmitting opening, but also makes the filling portion 11 and the side of the isolation structure 6 away from the substrate 1 more flat.

[0206] Optionally, the side of the pixel defining layer 5 exposed by the light-transmitting opening away from the substrate 1 includes a second plane parallel to the substrate 1. In this way, the side of the filling portion 11 away from the substrate 1 can more easily form a first plane.

[0207] Preferably, the filling portion 11 is made of a light-transmitting material.

[0208] Since the filling portion 11 is made of a light-transmitting material, the provision of the filling portion 11 is unlikely to affect the external light passing through the light-transmitting opening, and is unlikely to affect the transmittance of the display panel.

[0209] Optionally, the material of the filling part 11 includes organic material and / or inorganic material.

[0210] In the case where the filling portion 11 is made of a light-transmitting material, the filling portion 11 may be formed of an organic material and / or an inorganic material. In this way, a wider range of materials can be used for the filling portion 11 .

[0211] In another embodiment, see Figure 7The filling layer includes a first filling sublayer, a second filling sublayer and a third filling sublayer stacked in sequence along a direction away from the substrate 1, the first filling sublayer includes a plurality of first filling sub-portions 111 arranged at intervals, the second filling sublayer includes a plurality of second filling sub-portions 112 arranged at intervals, the third filling sublayer includes a plurality of third filling sub-portions 113 arranged at intervals, the filling portion 11 includes a first filling sub-portion 111, a second filling sub-portion 112 and a third filling sub-portion 113, and the third filling sub-portion 113 covers at least part of the side wall of the isolation structure 6 facing the light-transmitting opening.

[0212] Preferably, the third filling sub-portion 113 covers the side wall of the isolation structure 6 facing the light-transmitting opening.

[0213] Optionally, at least a portion of the third filling sub-portion 113 extends from the sidewall of the isolation structure 6 toward the light-transmitting opening to a side of the isolation structure 6 away from the substrate 1 .

[0214] Optionally, a first gap exists between the third filling sub-portion 113 located on the side of the isolation structure 6 away from the substrate 1 and the side of the isolation structure 6 away from the substrate 1 .

[0215] In this embodiment, the side wall of the isolation structure 6 facing the light-transmitting opening is mainly covered by the third filling sub-portion 113 , and the side wall of the isolation structure 6 facing the light-transmitting opening is mainly protected by the third filling sub-portion 113 .

[0216] Optionally, the pixel defining layer 5 defines a number of pixel blind holes 52 , the pixel opening 51 is connected to the corresponding isolation opening 7 , the pixel blind hole 52 does not penetrate the pixel defining layer 5 , the pixel blind hole 52 is connected to the corresponding light-transmitting opening, and part of the filling portion 11 is located within the pixel blind hole 52 .

[0217] Optionally, the orthographic projection of the pixel blind hole 52 on the substrate 1 is located within the orthographic projection of the light-transmitting opening on the substrate 1 .

[0218] Optionally, the first filling sub-portion 111 extends from a side of the pixel blind hole 52 close to the substrate 1 to a sidewall of the pixel blind hole 52 .

[0219] In this way, the morphology of the filling portion 11 in the light-transmitting opening is more consistent with the morphology of the light-emitting unit 9 in the isolation opening 7, thereby improving the overall performance of the display panel.

[0220] Optionally, the second filling sub-portion 112 extends to overlap the side wall of the isolation structure 6 facing the light-transmitting opening. The second filling sub-portion 112 is conductive, and the signal of the second electrode 4 can be transmitted through the isolation structure 6 and the second filling sub-portion 112, thereby further facilitating the transmission of the signal of the second electrode 4.

[0221] In some possible implementations, the first filling sub-portion 111 and the light-emitting functional portion 3 are made of the same layer and the same material.

[0222] Optionally, the second filling sub-portion 112 and the second electrode 4 are made of the same layer and material.

[0223] The first filling sub-portion 111 is formed while the light emitting functional portion 3 is formed. Thus, no special process is required to form the first filling sub-portion 111 , thereby reducing the process cost of forming the first filling sub-portion 111 .

[0224] The second filling sub-portion 112 is formed while the second electrode 4 is formed. Thus, there is no need to set up a special process to form the second filling sub-portion 112 , thereby reducing the process cost of forming the second filling sub-portion 112 .

[0225] Preferably, see again Figure 7 The display panel further includes a plurality of packaging units 12 located on a side of the light emitting unit 9 away from the substrate 1 . Parts of the packaging units 12 extend from the side of the isolation structure 6 toward the isolation opening 7 to the side of the isolation structure 6 away from the substrate 1 .

[0226] Optionally, a second gap exists between the packaging unit 12 located on the side of the isolation structure 6 away from the substrate 1 and the side of the isolation structure 6 away from the substrate 1 .

[0227] Optionally, a plurality of packaging units 12 are arranged at intervals on a side of the isolation structure 6 away from the substrate 1 .

[0228] During the patterning process of the light-emitting unit 9 , the first packaging material layer is disconnected at the isolation structure 6 to form the packaging unit 12 . The packaging unit 12 can completely and independently package the corresponding light-emitting unit 9 , thereby improving the display characteristics of the display panel.

[0229] Preferably, the third filling sub-portion 113 and the packaging unit 12 are made of the same layer and material.

[0230] The third filling sub-portion 113 is formed while the encapsulation unit 12 is formed. Thus, no special process is required to form the third filling sub-portion 113 , thereby reducing the process cost of forming the third filling sub-portion 113 .

[0231] For some possible implementations, see Figure 8a and Figure 8b The substrate 1 includes a base 19 , a conductive layer and an insulating layer 18 .

[0232] The conductive layer is located on one side of the substrate 19 and includes a plurality of conductive traces 17 arranged at intervals.

[0233] The insulating layer 18 is located on a side of the conductive layer away from the substrate 19 . A connecting through hole 181 penetrating the insulating layer 18 is provided along the thickness direction Z of the substrate 19 . The first electrode 2 is electrically connected to the conductive trace 17 via the connecting through hole 181 .

[0234] The substrate 1 further includes a pixel circuit located between the substrate 18 and the conductive layer, and the conductive traces are electrically connected to the pixel circuit. Thus, the signal of the pixel circuit can be transmitted to the first electrode 2 through the conductive traces 17, thereby causing the corresponding light-emitting unit 9 to emit light.

[0235] Preferably, along the thickness direction Z of the substrate 19 , the insulating layer 18 is further provided with a light-transmitting through hole 182 penetrating the insulating layer 18 , and the orthographic projection of the light-transmitting through hole 182 on the substrate 19 is located within the orthographic projection of the light-transmitting opening on the substrate 19 .

[0236] The insulating layer 18 can be a planarization layer of the display panel. The insulating layer 18 can block a certain amount of external light. In this embodiment, a light-transmitting through hole 182 is set at the position of the light-transmitting opening of the insulating layer 18, so that the amount of external light blocked by the insulating layer 18 can be reduced, thereby further improving the transmittance of the display panel.

[0237] Preferably, the orthographic projection of the light-transmitting opening on the substrate 19 is spaced apart from the orthographic projection of the first electrode 2 on the substrate 19 .

[0238] In this embodiment, the orthographic projection of the first electrode 2 on the substrate 19 is set to not overlap with the orthographic projection of the light-transmitting opening on the substrate 19, which can reduce the first electrode 2's shielding of external light, thereby further improving the transmittance of the display panel.

[0239] Preferably, the orthographic projection of the light-transmitting through hole 182 on the substrate 19 is spaced apart from the orthographic projection of the connecting through hole 181 on the substrate. In this way, the light-transmitting through hole 182 and the connecting through hole 181 do not affect each other.

[0240] Preferably, see Figure 9 The display panel further includes a second encapsulation layer 13 located on a side of the encapsulation unit 12 away from the substrate 1 and a third encapsulation layer 14 located on a side of the second encapsulation layer 13 away from the substrate 1 .

[0241] Optionally, the materials of the encapsulation unit 12 and the third encapsulation layer 14 both include inorganic materials, and the material of the second encapsulation layer 13 includes organic materials.

[0242] For example, the encapsulation unit 12 and the third encapsulation layer 14 can be formed by chemical vapor deposition (CVD), and the second encapsulation layer 13 can be formed by inkjet printing (IJP). The second encapsulation layer 13 and the third encapsulation layer 14 can provide a better encapsulation effect for the light-emitting unit 9, thereby further improving the encapsulation quality of the display panel.

[0243] For some possible implementations, see again Figure 8a and Figure 8b The isolation structure 6 includes a first isolation portion 61 and a second isolation portion 62 which are stacked in sequence along a direction away from the substrate 1. The orthographic projection of the side of the first isolation portion 61 away from the substrate 1 on the substrate 1 is located within the orthographic projection of the second isolation portion 62 on the substrate 1. The area of the orthographic projection of the side of the first isolation portion 61 away from the substrate 1 on the substrate 1 is smaller than the area of the orthographic projection of the second isolation portion 62 on the substrate 1.

[0244] Because the second isolating portion 62 is located on the side of the first isolating portion 61 away from the substrate 1 and the lateral width of the second isolating portion 62 is greater than the lateral width of the first isolating portion 61 in a plane parallel to the substrate 1, the second isolating portion 62 disconnects the light-emitting material layer and the second electrode material layer at the isolation structure 6. Thus, the isolation structure 6 formed by the first isolating portion 61 and the second isolating portion 62 makes it easier to independently package each light-emitting unit 9, thereby improving the packaging yield of the display panel.

[0245] Preferably, see again Figure 8a and Figure 8b The isolation structure 6 includes a conductive material, and the second electrode 4 of the light-emitting unit 9 is electrically connected to the first isolation portion 61. The first isolation portion 61 includes a conductive material, and the second electrode 4 corresponding to the light-emitting unit 9 extends to contact the sidewall of the first isolation portion 61 to achieve electrical connection between the second electrode 4 corresponding to the light-emitting unit 9 and the first isolation portion 61.

[0246] Preferably, see again Figure 9 The isolation structure 6 further includes a third isolation portion 63 located on a side of the first isolation portion 61 facing the substrate 1 , and the second electrode 4 of the light emitting unit 9 is electrically connected to the third isolation portion 63 .

[0247] Optionally, the material of the third isolation portion 63 includes molybdenum or titanium; and / or the material of the first isolation portion 61 includes aluminum, silver or copper; and / or the material of the second isolation portion 62 includes titanium or molybdenum.

[0248] The third isolation portion 63 includes a conductive material. The second electrode 4 corresponding to the light emitting unit 9 extends to contact the sidewall of the third isolation portion 63 to achieve electrical connection between the second electrode 4 corresponding to the light emitting unit 9 and the third isolation portion 63 .

[0249] For some possible implementations, see Figure 1 and Figure 10 The present application also provides a method for manufacturing a display panel, wherein the display panel includes a first display area AA1 and a second display area AA2 surrounding at least a portion of the first display area AA1, the method comprising:

[0250] S10: providing a substrate 1.

[0251] S11: A pixel defining material layer 15 and an isolation material layer 16 are sequentially formed on one side of the substrate 1, and the isolation material layer 16 is patterned to obtain an isolation structure 6 including a plurality of isolation openings 7 and a plurality of light-transmitting openings, and at least a portion of the light-emitting unit 9 is formed within the plurality of isolation openings 7, the plurality of isolation openings 7 are located in the first display area AA1 and the second display area AA2, the plurality of light-transmitting openings include a plurality of first light-transmitting sub-openings 8, and the plurality of first light-transmitting sub-openings 8 are located in the second display area AA2.

[0252] In the display panel formed by the above method, a first light-transmitting sub-opening 8 is formed in the second display area AA2, which can reduce the amount of external light blocked by the isolation structure 6 located in the second display area AA2. External light can pass through the first light-transmitting sub-opening 8, thereby improving the transmittance of the display panel and meeting the transparency requirements of the transparent screen.

[0253] Several specific preparation methods for forming the display panel are introduced below.

[0254] In the first embodiment, the steps of sequentially forming a pixel defining material layer 15 and an isolation material layer 16 on one side of a substrate 1, patterning the isolation material layer 16 to obtain an isolation structure 6 including a plurality of isolation openings 7 and a plurality of light-transmitting openings, and forming at least part of the light-emitting unit 9 within the plurality of isolation openings 7 include:

[0255] See Figure 11 , a pixel defining material layer 15 and an isolation material layer 16 are sequentially formed on one side of the substrate 1 .

[0256] See Figure 12, the isolation material layer 16 and the pixel defining material layer 15 are patterned in sequence to obtain an isolation material layer 16 including a first isolation opening 71 and multiple light-transmitting openings, and a pixel defining material layer 15 including a first pixel opening 511. The first pixel opening 511 is connected to the first isolation opening 71, and the multiple light-transmitting openings also include multiple second light-transmitting sub-openings 10. The multiple second light-transmitting sub-openings 10 are located in the first display area.

[0257] See Figure 13 , forming a filling layer, the filling layer includes a plurality of filling parts 11 arranged at intervals, at least part of the filling part 11 is located in the light-transmitting opening, and the filling part 11 covers at least part of the side wall of the isolation structure 6 facing the light-transmitting opening.

[0258] See Figure 14 , forming a first light-emitting unit and a first packaging unit 121 located on a side of the first light-emitting unit away from the substrate 1 , at least a portion of the first light-emitting unit is located in the first isolation opening 71 .

[0259] Since the filling portion 11 has been formed in the light-transmitting opening before the first light-emitting unit is formed, the filling portion 11 can protect the side wall of the isolation structure 6 facing the light-transmitting opening during the patterning of the first light-emitting unit, thereby preventing the side wall of the isolation structure 6 facing the light-transmitting opening from being easily etched.

[0260] See Figure 15 , the isolation material layer 16 including the first isolation opening 71 and the multiple light-transmitting openings, and the pixel-defining material layer 15 including the first pixel opening 511 are patterned in sequence, respectively obtaining the isolation material layer 16 including the second isolation opening 72, the first isolation opening 71 and the multiple light-transmitting openings, and the pixel-defining material layer 15 including the first pixel opening 511 and the second pixel opening 512, wherein the second pixel opening 512 is connected to the second isolation opening 72.

[0261] See Figure 16 , forming a second light-emitting unit and a second packaging unit 122 located on a side of the second light-emitting unit away from the substrate 1 , and at least a portion of the second light-emitting unit is located in the second isolation opening 72 .

[0262] Since the filling portion 11 has been formed in the light-transmitting opening before the second light-emitting unit is formed, the filling portion 11 can protect the side wall of the isolation structure 6 facing the light-transmitting opening during the patterning of the second light-emitting unit, thereby preventing the side wall of the isolation structure 6 facing the light-transmitting opening from being easily etched.

[0263] See Figure 17, an isolation material layer 16 is patterned including a first isolation opening 71, a second isolation opening 72 and a plurality of light-transmitting openings, and a pixel defining material layer 15 is patterned including a first pixel opening 511 and a second pixel opening 512, respectively obtaining an isolation structure 6 including a third isolation opening 73, a second isolation opening 72, a first isolation opening 71 and a plurality of light-transmitting openings, and a pixel defining layer 5 including a first pixel opening 511, a second pixel opening 512 and a third pixel opening 513, wherein the third pixel opening 513 is connected to the third isolation opening 73.

[0264] See Figure 18 , forming a third light-emitting unit and a third encapsulation unit 123 located on a side of the third light-emitting unit away from the substrate 1 , and at least a portion of the third light-emitting unit is located in the third isolation opening 73 .

[0265] Optionally, the first light emitting unit, the second light emitting unit and the third light emitting unit have different light emitting colors. For example, the light emitting color of the first light emitting unit may be blue, the light emitting color of the second light emitting unit may be green, and the light emitting color of the third light emitting unit may be red.

[0266] In this embodiment, the light-transmitting opening is opened together with the first isolation opening 71. Since the filling portion 11 has been formed in the light-transmitting opening before the first light-emitting unit, the second light-emitting unit and the third light-emitting unit are formed, the filling portion 11 can protect the side wall of the isolation structure 6 facing the light-transmitting opening during the patterning of the first light-emitting unit, the second light-emitting unit and the third light-emitting unit, so that it is not easy to etch the side wall of the isolation structure 6 facing the light-transmitting opening, thereby not affecting the transmission of the signal of the second electrode 4 of the light-emitting unit 9, and ultimately improving the display effect of the display panel.

[0267] In the second embodiment, the steps of sequentially forming a pixel defining material layer 15 and an isolation material layer 16 on one side of a substrate 1, patterning the isolation material layer 16 to obtain an isolation structure 6 including a plurality of isolation openings 7 and a plurality of light-transmitting openings, and forming at least part of the light-emitting unit 9 within the plurality of isolation openings 7 include:

[0268] Please see again Figure 11 , a pixel defining material layer 15 and an isolation material layer 16 are sequentially formed on one side of the substrate 1 .

[0269] See Figure 19 The isolation material layer 16 is patterned to obtain an isolation material layer 16 including a plurality of light-transmitting openings. The plurality of light-transmitting openings further include a plurality of second light-transmitting sub-openings 10. The plurality of second light-transmitting sub-openings 10 are located in the first display area.

[0270] See Figure 20, forming a filling layer, the filling layer includes a plurality of filling parts 11 arranged at intervals, at least part of the filling part 11 is located in the light-transmitting opening, and the filling part 11 covers at least part of the side wall of the isolation structure 6 facing the light-transmitting opening.

[0271] Please see again Figure 13 , patterning the isolation material layer 16 including the plurality of light-transmitting openings to obtain the isolation material layer 16 including the first isolation opening 71 and the plurality of light-transmitting openings.

[0272] Please see again Figure 14 , forming a first light-emitting unit, at least a portion of the first light-emitting unit is located in the first isolation opening 71.

[0273] Please see again Figure 15 The isolation material layer 16 including the first isolation opening 71 and the plurality of light-transmitting openings is patterned to obtain the isolation material layer 16 including the second isolation opening 72 , the first isolation opening 71 and the plurality of light-transmitting openings.

[0274] Please see again Figure 16 , forming a second light-emitting unit, at least a portion of the second light-emitting unit is located in the second isolation opening 72 .

[0276] Please see again Figure 18 , forming a third light-emitting unit, at least a portion of the third light-emitting unit is located in the third isolation opening 73.

[0277] In this embodiment, a light-transmitting opening is opened first, and then the first isolation opening 71 is opened. Since the filling portion 11 has been formed in the light-transmitting opening before the first light-emitting unit, the second light-emitting unit and the third light-emitting unit are formed, the filling portion 11 can protect the side wall of the isolation structure 6 facing the light-transmitting opening during the patterning of the first light-emitting unit, the second light-emitting unit and the third light-emitting unit, so that it is not easy to etch the side wall of the isolation structure 6 facing the light-transmitting opening, thereby not affecting the transmission of the signal of the second electrode 4 of the light-emitting unit 9, and ultimately improving the display effect of the display panel.

[0278] In the third embodiment, the steps of sequentially forming a pixel defining material layer 15 and an isolation material layer 16 on one side of a substrate 1, patterning the isolation material layer 16 to obtain an isolation structure 6 including a plurality of isolation openings 7 and a plurality of light-transmitting openings, and forming at least a portion of a light-emitting unit 9 within the plurality of isolation openings 7 include:

[0281] See Figure 22 , forming a first light-emitting unit, at least a portion of the first light-emitting unit is located in the first isolation opening 71.

[0282] See Figure 23 , patterning the isolation material layer 16 including the first isolation opening 71 to obtain the isolation material layer 16 including the second isolation opening 72 and the first isolation opening 71 .

[0283] See Figure 24 , forming a second light-emitting unit, at least a portion of the second light-emitting unit is located in the second isolation opening 72 .

[0284] See Figure 25 The isolation material layer 16 including the first isolation opening 71 and the second isolation opening 72 is patterned to obtain the isolation material layer 16 including the third isolation opening 73 , the second isolation opening 72 and the first isolation opening 71 .

[0285] See Figure 26 , forming a third light-emitting unit, at least a portion of the third light-emitting unit is located in the third isolation opening 73.

[0287] Please see again Figure 18 , forming a filling layer, the filling layer includes a plurality of filling parts 11 arranged at intervals, at least part of the filling part 11 is located in the light-transmitting opening, and the filling part 11 covers at least part of the side wall of the isolation structure 6 facing the light-transmitting opening.

[0288] In this embodiment, the first isolation opening 71, the second isolation opening 72 and the third isolation opening 73 are opened in sequence, and the first light-emitting unit, the second light-emitting unit and the third light-emitting unit are formed in sequence. The light-transmitting opening is formed after the third light-emitting unit is formed. In this way, in the process of patterning the first light-emitting unit, the second light-emitting unit and the third light-emitting unit, the isolation structure 6 will not be etched toward the side wall of the light-transmitting opening, so that it is not easy to affect the transmission of the signal of the second electrode 4 of the light-emitting unit 9, and ultimately the display effect of the display panel can be improved.

[0289] Please see again Figure 9 Since the filling portion 11 is provided in the light-transmitting opening, the filling portion 11 can fill the light-transmitting opening, thereby making the second encapsulation layer 13 flatter.

[0290] In the fourth embodiment, the steps of sequentially forming a pixel defining material layer 15 and an isolation material layer 16 on one side of a substrate 1, patterning the isolation material layer 16 to obtain an isolation structure 6 including a plurality of isolation openings 7 and a plurality of light-transmitting openings, and forming at least a portion of a light-emitting unit 9 within the plurality of isolation openings 7 include:

[0291] Please see again Figure 11 , a pixel defining material layer 15 and an isolation material layer 16 are sequentially formed on one side of the substrate 1 .

[0292] See Figure 28 The isolation material layer 16 is patterned to obtain an isolation material layer 16 including a first isolation opening 71 and a plurality of light-transmitting openings. The plurality of light-transmitting openings further include a plurality of second light-transmitting sub-openings 10. The plurality of second light-transmitting sub-openings 10 are located in the first display area.

[0296] See Figure 32The isolation material layer 16 including the first isolation opening 71 , the second isolation opening 72 and a plurality of light-transmitting openings is patterned to obtain an isolation structure 6 including the third isolation opening 73 , the second isolation opening 72 , the first isolation opening 71 and a plurality of light-transmitting openings.

[0297] See Figure 33 , forming a third light-emitting unit, at least a portion of the third light-emitting unit is located in the third isolation opening 73.

[0298] In this embodiment, the first isolation opening 71 and the light-transmitting opening are opened simultaneously, forming the first light-emitting unit and the filling portion 11 at the same time. In this way, no special process is required to form the filling portion 11, thereby reducing the process cost of forming the filling portion 11.

[0299] During the process of patterning the first light-emitting unit, the second light-emitting unit and the third light-emitting unit, the filling portion 11 can protect the side wall of the isolation structure 6 facing the light-transmitting opening, so that it is not easy to etch the side wall of the isolation structure 6 facing the light-transmitting opening, thereby not affecting the transmission of the signal of the second electrode 4 of the light-emitting unit 9, and ultimately improving the display effect of the display panel.

[0300] In a fifth embodiment, the steps of sequentially forming a pixel defining material layer 15 and an isolation material layer 16 on one side of a substrate 1, patterning the isolation material layer 16 to obtain an isolation structure 6 including a plurality of isolation openings 7 and a plurality of light-transmitting openings, and forming at least a portion of a light-emitting unit 9 within the plurality of isolation openings 7 include:

[0301] Please see again Figure 11 , a pixel defining material layer 15 and an isolation material layer 16 are sequentially formed on one side of the substrate 1 .

The filling portion 11 is formed while the second light-emitting unit is formed. In this way, no special process is required to form the filling portion 11, thereby reducing the process cost of forming the filling portion 11.

[0309] When the first light-emitting unit is patterned, no light-transmitting opening is formed. Therefore, when the first light-emitting unit is patterned, the side wall of the isolation structure 6 facing the light-transmitting opening is not etched. In the process of forming the second light-emitting unit and the third light-emitting unit, the filling portion 11 can protect the side wall of the isolation structure 6 facing the light-transmitting opening, so that it is not easy to etch the side wall of the isolation structure 6 facing the light-transmitting opening, thereby not affecting the transmission of the signal of the second electrode 4 of the light-emitting unit 9, and ultimately can improve the display effect of the display panel.
