Description

[Technical field]

[0001] <CROSS REFERENCE TO RELATED APPLICATIONS> This application claims priority to a Chinese patent application filed with the China Patent Office on September 13, 2022, with application number CN202211111292.7 and title "Organic light-emitting display panel, display device, and sealing method for display panel," the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to the field of display technology, and more particularly to an organic light-emitting display panel, a display device, and a sealing method for a display panel. [Background technology]

[0003] For the purposes of providing background information relevant to the present application, an organic light-emitting display (abbreviated as OLED) in the prior art is not necessarily a display manufactured using organic light-emitting diodes.

[0004] At present, OLED product touch technology occupies a large market share. The touch sensing circuit technology on the OLED cover plate is more mature. At present, in the technology where the touch capacitive screen is placed in the package, the metal touch line bound to the touch area is formed on the cover plate, and when the hard screen is sealed with the sealing layer, the unevenness of the laser light transmittance causes uneven sintering, which causes problems such as overflow, bubbles, and cracks in the sealing layer, affecting the sealing effect and disconnection failure.

[0005] Currently, the problem of uneven sintering is alleviated by performing laser sintering including the touch binding pin area by increasing the laser energy or slowing down the moving speed of the laser head. However, when the laser energy is reduced and the moving speed of the laser head is slowed down, the energy cannot be increased to be precisely controlled so that it is present only in the touch binding pin area. Therefore, when the laser energy is located in a normal area, the energy changes suddenly, causing a sudden change in the shape of the sealing layer in the normal area, making it easier for cracks to occur in the sealing layer and causing sealing failure. Summary of the Invention [Problem to be solved by the invention]

[0006] An object of the present invention is to provide an organic light-emitting display panel, a display device, and a sealing method for a display panel that avoids sealing unevenness and improves the sealing effect.

[0007] The present application discloses an organic light emitting display panel, which includes a cover plate, a substrate, and an encapsulation layer, the cover plate is disposed opposite to the substrate, and the encapsulation layer is disposed between the cover plate and the substrate, the organic light emitting display panel further includes a touch line, the touch line is formed on the cover plate, a touch binding pin is disposed on an edge of the cover plate, the touch binding pin is connected to the touch line, and a plurality of shielding terminals are disposed on both sides of the touch binding pin, respectively, the touch binding pin and the shielding terminal are disposed corresponding to the encapsulation layer, wherein a length of the plurality of shielding terminals is equal to a length of the touch binding pin, and a width of the plurality of shielding terminals gradually decreases along a direction away from the touch binding pin.

[0008] The present application further discloses a display device, which includes an outer cover plate and an organic light emitting display panel, the outer cover plate being disposed on one side of a light emitting surface of the organic light emitting display panel.

[0009] The present application further discloses a display panel sealing method for sealing an organic light-emitting display panel, Applying a sealing layer between the cover plate and the substrate in accordance with the edge position; using a laser device to laser sinter the encapsulation layer of the display panel along a preset path; When detecting that the laser device has moved to the normal area, sintering the sealing layer in the normal area based on a first preset laser energy and a first preset moving speed; When detecting that the laser device has moved to the buffer region, gradually increasing the laser energy and / or gradually decreasing the moving speed to sinter the sealing layer in the buffer region; and increasing the laser energy when the laser device detects that the laser device has moved to the touch binding pin area, thereby sintering the sealing layer in the touch binding pin area. Here, the cover plate is formed with a touch binding pin and shielding terminals located on both sides of the touch binding pin, and the laser device has a same laser sintering ratio between the buffer region and the touch binding pin region in the normal region.

[0010] The present application provides multiple shielding terminals on both sides of the touch binding pin, so that the length of the multiple shielding terminals matches the length of the touch binding pin, and the width of the multiple shielding terminals decreases in the direction away from the touch binding pin. When laser processing is performed in this manner, control of the energy change or moving speed of the laser head is started in the area where the shielding terminals are installed, and the shielding terminals, which decrease in width in the direction away from the touch binding pin, perform an energy buffering action on the area where the shielding terminals are present, thereby avoiding the occurrence of steps due to sudden changes in laser energy, and avoiding the problem that the step due to the sudden change in energy is too large at the contact point between the non-touch binding pin area and the touch binding pin area, making it easy for uneven sealing to occur.

[Figure 6] 2 is a flowchart of a sealing method for a display panel according to the present application. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] FIG. 1 is a block diagram of a display device of the present application, FIG. 2 is a structural schematic diagram of an organic light-emitting display panel of the present application, FIG. 3 is a cross-sectional structural schematic diagram along the cross-sectional line A-A' of FIG. 1, and FIG. 4 is a layout schematic diagram of a touch binding pin and a shielding terminal of the present application. As shown in FIG. 1, the present application discloses a display device 10, which includes an outer cover 200 and an organic light-emitting display panel 100, and the outer cover plate 200 is installed on one side of the organic light-emitting display panel 100. Specifically, as can be seen with reference to FIGS. 2 and 3, the organic light-emitting display panel 100 includes a cover plate 110, a substrate 120 and an encapsulation layer 130, and the cover plate 110 is disposed opposite the substrate 120. The organic light emitting display panel 100 further includes a touch line 140, the touch line 140 is formed on the cover plate 110, a touch binding pin 141 is provided at an edge of the cover plate 110, the touch binding pin 141 is connected to the touch line 140, and a plurality of shielding terminals 150 are provided on both sides of the touch binding pin 141, wherein a length of the plurality of shielding terminals 150 is equal to a length of the touch binding pin 141, and a width of the plurality of shielding terminals 150 gradually decreases along a direction away from the touch binding pin 141.

[0013] For the method of laser sintering including the touch binding pin region 180 by increasing the laser energy or decreasing the moving speed of the laser head, the present application provides a plurality of shielding terminals 150 on both sides of the touch binding pin 141, the length of the plurality of shielding terminals 150 is the same as the length of the touch binding pin 141, and the width of the plurality of shielding terminals 150 gradually decreases along the direction away from the touch binding pin 141. In this way, when performing laser processing, the energy of the laser head can be controlled to gradually increase or the laser head to gradually descend in the region where the shielding terminals 150 are installed. The shielding terminals 150 whose width gradually decreases along the direction away from the touch binding pin 141 perform an energy buffering effect on the region where the shielding terminals 150 are present, and the occurrence of a step due to a sudden change in laser energy is avoided, and the problem of uneven sealing caused by too large a step due to a sudden change in energy at the contact point between the non-touch binding pin 141 region and the touch binding pin 141 region is avoided.

[0014] Here, the sealing layer 130 is a glass adhesive, which has a certain stability and poor fluidity, and is relatively easy to mold when applied for sealing, and can be deformed and attached and adsorbed even after absorbing heat, resulting in a high sealing effect. Of course, other suitable sealing materials can also be used for sealing, and the sealing effect and stability can be guaranteed.

[0015] The present application will now be described in detail with reference to the drawings and selective embodiments. EXAMPLES

[0016] The direction of the arrow in FIG. 2 indicates the direction of the preset path of the laser head, and the direction of the arrow in FIG. 3 indicates the irradiation direction of the laser light. As shown in FIGS. 2 and 3, the area where the touch binding pins 141 are installed is the touch binding pin area 180, the area where the shielding terminals 150 are installed is the buffer area 170, and the area where the touch binding pins 141 and the shielding terminals 150 are not installed is the normal area 160. In the case of sealing, the laser light travels around the edge of the sealing layer 130 along the normal area 160, the buffer area 170, and the touch binding pin area 180 of the display panel to perform sintering sealing.

[0017] As shown in FIG. 2, the organic light-emitting display panel has four sides, e, f, g and h, respectively, and the touch binding pins and the shielding terminals are arranged to extend in a direction parallel to e and g, i.e., their length, and the touch binding pins and the shielding terminals are arranged to extend in a direction of f and h, i.e., their width.

[0018] As shown in FIG. 4 , the width of the shielding terminal 150 is indicated by a, the distance between adjacent shielding terminals 150 from the side of the first shielding terminal 150 away from the second shielding terminal 150 to the side of the second shielding terminal 150 closer to the first shielding terminal 150 is indicated by b, and the distance between two adjacent shielding terminals 150 is indicated by c.

[0019] 3, the width of the shielding terminal 150 adjacent to the touch binding pin 141 is equal to the width of the touch binding pin 141, the intervals between adjacent touch binding pins 141 are equal, the intervals between adjacent shielding terminals 150 are equal, the intervals between adjacent touch binding pins 141 and shielding terminals 150 are equal, and the width of the shielding terminals 150 decreases by a first preset value along a direction away from the touch binding pin 141. In this way, the arrangement pitches of the touch binding pins and the shielding terminals are all equal and uniform. Here, the first preset value is 10 μm. That is, when the interval c between two adjacent shield terminals 150 along the direction away from the touch binding pin 141 does not change, simultaneously, a is gradually decreased by a first preset value. For example, when the interval b from the shield terminal 150 closest to the touch binding pin 141 to the side edge of the first shield terminal 150 adjacent to the shield terminal 150, which is far from the second shield terminal 150, to the side edge of the second shield terminal 150 close to the first shield terminal 150 is 250 um, the width a of the first shield terminal 150 is 130 um, and the interval c between the first shield terminal 150 and the second shield terminal 150 is 120 um, then a is decreased by a first preset value of 10 um, i.e., If the width a of the second shielding terminal 150 is 130um-10um=120um and the width a of the third shielding terminal 150 is 120um-10um=110um, then b is the width of the second shielding terminal 150 plus the interval between the second shielding terminal 150 and the third shielding terminal 150, i.e., 120um+120um=240um, that is, the interval b from the second shielding terminal 150 to the third shielding terminal 150 is 250um-10um=240um. By analogy therewith, the adjacent shielding terminals 150, b and a are arranged to decrease simultaneously by a first preset value, and at this time, the ratio of the arrangement, etc. between two adjacent shielding terminals 150 along the direction away from the touch binding pin 141 is uniform.

[0020] When the laser light of the laser head performs laser sealing on the area of ​​the sealing layer 130 along a preset path, when it reaches the buffer area 170, at this time, the width of the two adjacent shielding terminals 150 gradually increases along the direction approaching the touch binding pin 141, and when the laser head is controlled to gradually increase the energy, the energy is power multiplied by time. At this time, if the moving speed of the laser head does not change (i.e., the time does not change), when the power of the laser head gradually increases along the preset path, the energy that the laser head reaches the touch pin area gradually becomes larger, and when it reaches the touch binding pin area 180, the laser light of the laser head becomes maximum. However, increasing the laser energy of the laser head is a gradual process, but due to the presence of the uniformly arranged shielding terminals 150, the amount of energy irradiated to the area where the shielding terminals 150 are located when the laser light is irradiated during the process of the laser head moving is almost the same, that is, the amount of energy is the same as the amount of heat absorbed by the glass adhesive by the laser light. Therefore, in the sealing process, the problem of the non-touch binding pin area being unevenly sealed due to a large energy drop caused by a sudden change in the laser irradiation energy does not occur. When the laser light is irradiated to the touch binding pin 141 area, the energy also increases according to the preset increase and reaches an energy value that can firmly seal the touch binding pin area 180, making the entire sealing process uniform and strong, and avoiding the problem of uneven sealing.

[0021] Conversely, when the laser light moves to the normal area 160 via the touch binding pin area 180, the irradiation energy of the laser light controlling the laser head gradually decreases. In this case, by gradually decreasing the energy in the buffer area 170, a sudden change in energy can be avoided, which would cause a sudden change in the shape of the sealing layer 130 and problems such as cracks. In addition, the sealing ratio of each area in the entire sealing process can be made as equal as possible to improve the overall sealing effect and increase the sealing strength.

[0022] Similarly, when the moving speed of the laser head is reduced, the moving time becomes longer, so that the accumulated energy can be increased and a uniform sealing effect can be achieved. In addition, the change in the laser light irradiation energy of the laser head can be adjusted to match the moving descent speed of the laser head, and settings and combinations can be made according to specific situations, and the explanation will be omitted here.

[0023] In addition, in this embodiment, along a direction away from the touch binding pin 141, the width of the multiple shielding terminals 150 is gradually decreased by a first preset value, and the interval between two adjacent shielding terminals 150 is gradually decreased by a second preset value, and the first preset value is equal to the second preset value. That is, the shielding terminals 150 are disposed so that the width of the shielding terminals 150 and the interval between two adjacent shielding terminals 150 are simultaneously decreased by the same preset value, and a is decreased by a first preset value of 10 um, that is, the width a of the second shielding terminal 150 is 130 um-10 um=120 um, the width a of the third shielding terminal 150 is 120 um-10 um=110 um, and the interval c between the second shielding terminal 150 and the third shielding terminal 150 is decreased by a second preset value of 10 um, that is, 120 um-10 um=110 um, and b is the width of the second shielding terminal 150. b is the sum of the distance between the second shielding terminal 150 and the third shielding terminal 150, i.e., 120um+110um=230um, i.e., b is 250um-20um=230um. By analogy therewith, when the multiple shielding terminals 150 are arranged in this step-down manner, the step-down value of b is somewhat large. In this case, if the arrangement of the shielding terminals 150 is relatively dense, the shielding terminals 150 installed in the buffer region 170 can be arranged opposite each other, and the step-down manner of the arrangement of the multiple shielding terminals 150 is also relatively uniform, so that a relatively uniform sealing effect can be achieved during laser irradiation.

[0024] Of course, the width of the shielding terminals 150 may be gradually decreased by a first preset value along the direction away from the touch binding pin 141, and the interval between two adjacent shielding terminals 150 may be gradually increased by a second preset value, and the first preset value is equal to the second preset value, so that the shielding terminals 150 may be arranged in a gradually decreasing width. In this case, when the interval between each two shielding terminals 150 is wide, that is, the shielding terminals 150 are sparsely arranged, and the laser light is irradiated, the energy of the laser light transmitted through each of the two shielding terminals 150 and irradiated to the sealing layer 130 is large, and the sealing effect between the cover plate 110 and the substrate 120 is relatively better after absorption by the sealing layer 130. However, since the shielding terminals 150 are arranged to be gradually decreased in the direction away from the touch binding pin 141, the uniformity of the sealing can be improved by controlling the energy or moving speed of the laser head even when working with a laser head.

[0025] Here, the material of the shielding terminals 150 is the same as the material of the touch binding pins 141, and the thickness of the shielding terminals 150 is equal to the thickness of the touch binding pins 141. By using the same material and manufacturing process, it is possible to save materials and shorten the manufacturing process, and by using the same thickness, when a laser beam is irradiated, the laser beam transmittance of the shielding terminals 150 and the touch binding pins 141 is the same, and the problem of the difference in the amount of light absorbed by the sealing layer 130 due to the unevenness of the transmittance, which causes uneven sealing of the sealing layer 130, can be avoided.

[0026] In this embodiment, the shielding terminal 150 may be a metal material, and the touch binding pin 141 is generally also a metal material, so that the uniformity of light blocking can be achieved, and when irradiating the laser light, if the energy increasing control is relatively good, the energy can be increased at the same rate. Of course, the shielding terminal 150 may be manufactured with a black matrix, a transparent electrode, or a color resist material, in this case, the material of the shielding terminal 150 and the material of the touch binding pin 141 are different, which is favorable for the device to detect and distinguish the touch binding pin area 180, the buffer area 170, and the normal area 160, and the moving speed or energy of the laser head can be better controlled, and the sealing can be better.

[0027] As shown in FIG. 3, the organic light-emitting display panel 100 further includes an inorganic layer 190, which is disposed between the encapsulating layer 130 and the substrate 120. After forming the inorganic layer 190 on the substrate 120, the encapsulating layer 130 can also be recoated. EXAMPLES

[0028] 4 is a schematic diagram of the layout of the shielding terminal according to the second embodiment of the present application. As shown in FIG. 4, this embodiment is different from the first embodiment in that the shielding terminal 150 closest to the touch binding pin 141 has a slope 151 on the side adjacent to the touch binding pin 141, that is, the shielding terminal 150 has a triangular structure. When the shielding terminal 150 is made of a metal material, the metal material itself has a light-shielding effect and a certain reflective light effect, and the side adjacent to the touch binding pin 141 is made into a slope 151, forming an appropriate reflective portion of the laser light, and a part of the laser light is reflected by the slope 151 to the sealing layer 130 corresponding to the touch binding pin region 180, thereby increasing the amount of heat of the laser light that the sealing layer 130 at that position can absorb, and increasing the sealing adhesive force of the sealing layer 130 at that position, thereby achieving the effect of ideal sealing uniformity.

[0029] Here, the included angle between the inclined surface 151 and the side edge of the cover plate is d, and the gradient of the inclined surface 151 is 45° or more and less than 90°, that is, 45°≦d<90°. The greater the gradient of the inclined surface 151, the more the amount of laser light reflected to the touch binding pin area 180 will be. At this time, the existence of the inclined surface 151 allows the laser light to be reflected to the touch binding pin 141 and refracted to enter the area corresponding to the touch binding pin 141.

[0030] A reflective material may be installed on the inclined surface 151 to reflect more laser light energy, so that more laser light energy can be reflected to the sealing layer 130 corresponding to the touch binding pin area 180 according to the gradient of the inclined surface 151, so that the sealing layer 130 in the area can absorb more laser light energy, and improve the sealing adhesion strength of the sealing layer 130 in the area.

[0031] When the shielding terminal 150 is made of a black matrix, a transparent electrode, or a color resist material, the light transmittance of the inclined surface 151 can be gradually decreased along the inclination direction of the inclined surface 151, that is, the closer to the cover plate 110, the lower the light transmittance of the shielding terminal 150 having the inclined surface 151. By designing the light transmittance differently in this way, the energy absorption at the position during the irradiation of the laser light can be uniformly processed, and the sudden change of the energy at the position is also a process of gradually increasing or decreasing, so that the sudden change of the potential energy is too large, and the sudden change of the shape of the encapsulation layer 130 is serious, which affects the encapsulation effect. Of course, when the shielding terminal 150 adopts a semi-transparent material, the thickness of the shielding terminal 150 can be made relatively thicker than the thickness of the touch binding pin 141 to enhance the light shielding ability of the shielding terminal 150, and the laser light energy absorbed in the buffer region 170 can be made to match the touch binding pin region 180 and the normal region 160 as much as possible, thereby avoiding the sudden change of the shape of the encapsulation layer 130.

[0032] In addition, in this embodiment, the shielding terminal 150 closest to the touch binding pin 141 may have a structure with another inclined surface 151, for example, the inclined surface 151 may be arc-shaped, and the arc-shaped arc surface faces the touch binding pin 141, which is favorable for reflecting laser light, or the shielding terminal 150 may have a rectangular structure with an inclined surface 151, which can be specifically set according to actual conditions, and at the same time, better sealing uniformity can be achieved according to the irradiation energy or moving speed of the laser head laser light.

[0033] FIG. 6 is a flow chart of a sealing method for a display panel according to the present application. As shown in FIG. 6, the present application discloses a sealing method for sealing the above-mentioned organic light-emitting display panel, S1 applies a sealing layer between the cover plate and the substrate in accordance with the edge position; S2: laser sintering the sealing layer of the display panel along a preset path using a laser device; Sintering the sealing layer in the normal area based on a first preset laser energy and a first preset moving speed when detecting that the laser device has moved to the normal area (S3); S4, when detecting that the laser device has moved to the buffer region, gradually increasing the laser energy and / or gradually decreasing the moving speed to sinter the sealing layer in the buffer region; S5, when detecting that the laser device has moved to the touch binding pin area, increasing the laser energy to sinter the sealing layer in the touch binding pin area; Here, the cover plate is formed with a touch binding pin and shielding terminals located on both sides of the touch binding pin, and the laser device has a same laser sintering ratio between the buffer area and the touch binding pin area in the normal area, and after sealing, the sealing area of ​​the display panel is uniformly sealed.

[0034] In addition, in step 5, by slowing down the moving speed of the laser head, it is possible to cooperate with the light-shielding terminal to improve the sealing effect and achieve good uniformity. Of course, this can also be done simultaneously with the moving speed of the laser head by changing the laser energy.

[0035] In addition, although the inventive concept of the present application can be formed into a great number of embodiments, the number of application documents is limited and it is not possible to list them one by one. Therefore, under the premise that there is no contradiction, new embodiments may be formed by arbitrarily combining each of the embodiments or each of the technical features described above, and after combining each of the embodiments or technical features, the original technical effect can be enhanced.

[0036] Furthermore, the limitations of each step in this solution do not limit the order of the steps, provided that they do not affect the implementation of the specific solution. The steps described above may be performed first, later, or simultaneously. As long as the solution can be implemented, they should be considered to fall within the scope of protection of this application.

[0037] The above is a further detailed description of the present application with reference to specific embodiments, and the specific implementation of the present application cannot be deemed to be limited to these descriptions. Those skilled in the art of the present application may make some simple derivations or substitutions without departing from the concept of the present application, and all of them should be considered to be within the protection scope of the present application.
