For example, hydrochloric acid may be added to adjust the pH of the solution to 3, and the hydrolysis may be carried out at 50 ℃ for 12 hours after adjusting the pH. The selected acid can be hydrochloric acid and ethanol which are mixed according to the volume ratio of 1:20 to form a hydrochloric acid alcohol solution, the hydrochloric acid alcohol solution can also be used for adjusting the pH value, and the pH value adjusting effect and the subsequent hydrolysis condition control of the hydrochloric acid alcohol solution are consistent with those of hydrochloric acid, so that the details are not repeated.

Carbon dioxide (CO)₂) When the drying treatment is performed by a carbon dioxide supercritical drying process, which is gaseous at room temperature and atmospheric pressure, an evaporation process does not occur when a limit of constant temperature and high pressure, a so-called supercritical point, is exceeded, and thus, carbon dioxide is in a supercritical state where gas and liquid cannot be distinguished, and carbon dioxide in the supercritical state is referred to as "supercritical carbon dioxide". For supercritical carbon dioxide, since the density of molecules is close to that of a liquid, but the viscosity is low, supercritical carbon dioxide has a behavior close to that of a gas. In addition, since diffusion is fast and thermal conductivity is high, drying efficiency is high and drying process time is reduced.

The patterning step includes: coating photoresist, exposing, developing, etching, stripping photoresist and the like.

At least one (for example, one) through hole 10 may be formed on the display panel 1 by laser drilling in a subsequent process step, the through hole 10 penetrates through at least one (for example, two) sub-pixels P, and each of the plurality of sub-pixels P penetrated by the same through hole 10 is adjacent to at least one (for example, one) of the other plurality of sub-pixels P penetrated by the same through hole 10. At this time, the pixel defining layer pattern surrounding the plurality of sub-pixels P is a first pattern 51. For example, the via hole 10 penetrates two adjacent sub-pixels P, and the pixel defining layer pattern surrounding the two sub-pixels P is a first pattern 51. The minimum distance between the orthographic projection of the outer wall of each first pattern 51 on the driving back plate 20 and the orthographic projection of the laser cutting path 11 of the through hole 10 contained in the first pattern on the driving back plate 20 is d, wherein d is more than 0.1mm and less than or equal to 0.5mm, namely the minimum value of the area width d of the non-overlapping area 512 is more than 0.1mm and less than or equal to 0.5 mm.

Illustratively, referring to fig. 3 and 9, the area of the display panel 1 where the through holes 10 are provided is a perforated area 521, and the other area of the display panel 1 where the through holes 10 are not provided is a non-perforated area 522.

The light-emitting layer 30 further includes two electrode layers, one of which is an anode and the other is a cathode. Illustratively, the anode electrode may be formed before the first pattern Layer 50 is formed, and the cathode electrode may be formed after an Electron Injection Layer (EIL) is formed.

Referring to fig. 6 (b), 6 (c), and 6 (d), when the first pattern layer 50 is used as a pixel defining layer of the display panel 1, since the first pattern layer 50 is already formed, corresponding film layers are deposited on the first pattern 51 while sequentially forming a plurality of film layers included in the light emitting layer 30. Before forming the cathode of the light emitting layer 30, the film layer deposited on the first pattern 51 may be removed by at least one (e.g., may be multiple) etching process, so that the cathode may be simultaneously deposited on the electron injection layer and the first pattern layer 50. After the cathode is formed, the method for manufacturing the display panel further comprises the following steps: the annular perforation-protected area 53 is produced. Specifically, a plurality of first annular hollow areas 531 may be etched on the cathode through exposure and development, an orthographic projection of the first annular hollow areas 531 on the driving back plate 20 coincides with the non-coinciding area 512, a width k of the first annular hollow areas 531 is 200 to 500 μm, for example, the width of the first annular hollow areas 531 may be 300 μm. After the first annular hollow-out region 531 is formed, each first pattern 51 is etched by exposure and development using a mask plate which is the same as that used for forming the first annular hollow-out region 531, so as to form at least one (for example, a plurality of) second annular hollow-out regions 532 which are disposed in the same layer as the first pattern layer 50, and each second annular hollow-out region 532 surrounds one light emitting device L. Each annular perforated guard area 53 comprises a first annular hollowed-out area 531 and a second annular hollowed-out area 532 which are exactly coincident in orthographic projection on the drive back plate 20.

Illustratively, when the first pattern layer 50 does not serve as a pixel defining layer and each first pattern 51 has a shape of a solid cylinder, after the electron injection layer of the light emitting layer 30 is formed, a corresponding film layer is deposited on the first pattern 51, and the film layer deposited on the first pattern 51 may be removed by at least one (e.g., a plurality of) etching processes.

And S403, forming the packaging layer 40.

Exemplarily, referring to (e) in fig. 6, after forming the light emitting layer 30, forming the display panel to be perforated further includes: an encapsulation layer 40 is formed on the side of the light-emitting layer 30 remote from the driving backplane 20. Specifically, the material of the encapsulation layer 40 may be tetrafluoroethylene (hereinafter referred to as TFE), epoxy resin, or the like. Specifically, due to the presence of the annular punch-out protection area 53, the encapsulation layer 40 may fill at least a portion of the annular punch-out protection area 53 when the encapsulation layer 40 is formed.

And S404, forming the through hole 10.

Exemplarily, referring to fig. 6 (f) and fig. 8 and 11, after forming the encapsulation layer 40, cutting the display panel to be punched along the laser cutting path 11 by using a laser to form the display panel 1 having at least one through hole 10 includes: forming at least one (for example, one) through hole 10 penetrating the driving back plate 20, the light emitting layer 30 and the encapsulation layer 40 along a laser cutting path 11, the laser cutting path 11 being within a range defined by the first pattern layer 50; the light emitting layer 30 has a sidewall 31 near the through hole 10, and the aerogel composite is disposed between the sidewall 31 of the light emitting layer 30 and the wall of the through hole 10 and filled in the gap between the encapsulation layer 40 and the driving back plate 20.

Specifically, the through hole 10 is formed by laser burning, and the laser cuts along the laser cutting path 11, that is, the main body of the laser cut is the first pattern 51 in the first pattern layer 50. Because the temperature of laser cutting is higher, the aerogel combined material that cutting route department formed first pattern 51 absorbs heat and melts, the aerogel combined material after melting can be at pulse laser's effect down to both sides diffusion, under protective gas (inert gas) or protective solution atmosphere, the aerogel combined material after completely melting can fill in the clearance between encapsulated layer 40 and drive backplate 20, form fine and close protective layer between the lateral wall 31 of luminescent layer 30 and the pore wall of through-hole 10, thereby avoid making the steam invade the device at encapsulated layer 40 after laser punching because of encapsulated layer 40 encapsulation is not in place, lead to the problem of device inefficacy. Meanwhile, the aerogel composite material contains carbon elements, so that the aerogel composite material has a better heat absorption effect, and can absorb more heat when being heated and melted at high temperature, thereby reducing the damage degree of the heat to the light-emitting device L of the peripheral light-emitting layer 30.

Illustratively, when the annular hole-punching protection region 53 exists in the display panel 1, when laser punching is performed, a gap exists between the first pattern 51 and the light-emitting device L due to the existence of the annular hole-punching protection region 53, and damage to the light-emitting device L caused by heat released by laser burning can be further reduced on the basis of heat absorption by melting of the aerosol composite material.

Exemplarily, when the substrate of the driving backplate 20 is a flexible substrate, the flexible substrate is carried on the rigid substrate in the manufacturing process, and after the laser drilling is completed, the flexible substrate and the rigid substrate can be separated to form the display panel 1; when the substrate is a rigid substrate, the display panel 1 can be obtained after laser drilling is completed.

The first pattern 51 may be provided only as spacers 90 in the perforated areas, and in the non-perforated areas the spacers 90 are still made of conventional materials. Specifically, the first pattern 51 is disposed on the same layer as the pixel defining layer of the display panel 1, and may be formed through a one-time patterning process using an inkjet printing technique.
