[0042] Organic light emitting diodes (OLEDs) emit light by applying a corresponding voltage between the pixel electrode and the common electrode. Figure 3 A pixel 25 of the display panel 2 generally includes a red sub-pixel 251, a green sub-pixel 252 and a blue sub-pixel 253. The three sub-pixels emit light of different stimulus values ​​to synthesize corresponding luminous colors. At this time, the voltages applied across the three sub-pixels are different.

[0043] There is a voltage difference between the red sub-pixel 251 and the green sub-pixel 252, and between the green sub-pixel 252 and the blue sub-pixel 253. Figure 1 As shown, the common layer 23 covers the entire pixel 25. When the voltages of the three sub-pixels are different, the carriers of one sub-pixel will leak laterally to another adjacent sub-pixel, resulting in a decrease in the number of carriers reaching the luminous recombination area of ​​the sub-pixel. The luminous amount of the sub-pixel does not reach the expected value, and the color of the synthesized light also does not reach the expected value.

[0044] Based on this, the present disclosure provides a partition device 1. Figures 2 to 11As shown, the partition device 1 is used for a display panel 2, the display panel 2 includes a pixel definition layer 22 and a common layer 23, the pixel definition layer 22 includes a plurality of pixel definition parts 221, pixel openings 222 are formed between the pixel definition parts 221, the common layer 23 covers the pixel definition parts 221 and the pixel openings 222, the partition device 1 includes an adsorption plate 11, a conductive ejector pin 12 and an ionic liquid 13, the conductive ejector pin 12 is arranged on one side of the adsorption plate 11; the ionic liquid 13 adheres to the conductive ejector pin 12, and the ionic liquid 13 is used to dissolve the common layer 23 between two adjacent pixel openings 222.

[0045] The partition device 1 includes an adsorption plate 11, on which a conductive pin 12 is provided, and on which an ionic liquid 13 is adhered. The adsorption plate 11 is controlled to be close to a common layer 23 so that the conductive pin 12 and the ionic liquid 13 contact the overlapping portion of the common layer 23 and the pixel definition portion 221, and the conductive pin 12 is controlled to move on the common layer 23 along the contour of the pixel opening 222 to form a partition groove 24 to partition the common layer 23 between two adjacent pixel openings 222, thereby isolating the connection between adjacent sub-pixels, thereby preventing the carriers of one sub-pixel from leaking laterally to another adjacent sub-pixel, and ensuring that the luminescence of the sub-pixel does not reach the expected value.

[0046] The partition device 1 involved in the embodiment of the present disclosure is described in detail below with reference to specific examples.

[0047] like Figure 2 As shown, the partition device 1 is used for a display panel 2, which includes a driving backplane 21, a pixel definition layer 22 and a common layer 23. The pixel definition layer 22 is arranged on one side of the driving backplane 21, and the pixel definition layer 22 includes a plurality of pixel definition parts 221. Pixel openings 222 are formed between the pixel definition parts 221. The common layer 23 is arranged on a side of the pixel definition layer 22 away from the driving backplane 21, and the common layer 23 covers the pixel definition parts 221 and the pixel openings 222.

[0048] The partition device 1 includes an adsorption plate 11, and a conductive pin 12 is provided on one side of the adsorption plate 11. The number of the conductive pins 12 is multiple. The partition device 1 also includes a conductive connecting portion 14, and the conductive connecting portion 14 is connected to the multiple conductive pins 12. An ionic liquid 13 is adhered to the conductive pins 12, and the ionic liquid 13 is used to dissolve the common layer 23 between two adjacent pixel openings 222. The common layer 23 is easily soluble in the ionic liquid 13. Almost as soon as it is touched with a little ionic liquid 13, the common layer 23 will be dissolved together with the ionic liquid 13 and will easily fall off from the pixel definition layer 22. In addition, the selected ionic liquid 13 must also have a certain conductivity and viscosity, so that it can be more firmly attached to the conductive pins 12 and will not fall off during the process production.

[0049] The ionic liquid 13 includes inorganic anions and organic cations. The ionic liquid 13 is a relatively stable compound that can stably exist in a wide range of temperature and pressure, can dissolve the common layer 23 well, and has certain viscosity, hydrophilicity and conductivity. The organic cations of the ionic liquid 13 can be: imidazolium cations with alkyl long chain structures such as a variety of cations [C2Im]+, [C3Im]+, [C4Im]+, [C5Im]+, [C2Em]+, [C3Em]+, [C4Em]+, [C5Em]+, [C6Em]+, and the inorganic anions can be BF4-, NO3-, Ac- (acetic acid anion), PF6-, X- (halogen anion). The ionic liquid 13 includes at least one inorganic anion and at least one organic cation.

[0050] The conductive pin 12 can be made of any conductive material, such as iron, gold, silver, aluminum, and metal oxides corresponding to iron, gold, silver, and aluminum. The conductive pin 12 can also be made of other inorganic and organic conductive materials. Figure 3 As shown, a red sub-pixel 251, a green sub-pixel 252 and a blue sub-pixel 253 are respectively provided in the pixel opening 222. The distance between two adjacent conductive pins 12 along the first direction is greater than or equal to the length of the pixel opening 222, and less than the sum of the length of the pixel opening 222 and the width of the pixel definition portion 221. The distance between two adjacent conductive pins 12 along the second direction is greater than or equal to the width of the pixel opening 222, and less than the sum of the width of the pixel opening 222 and the width of the pixel definition portion 221. The first direction is the same as the length direction of the pixel opening 222, and the second direction is the same as the width direction of the pixel opening 222. After the conductive pins 12 move in the first direction to dissolve the common layer 23, they can turn to move in the second direction to continue to dissolve the common layer 23. It should be noted that the first direction is Figure 3 The x direction shown in the figure is Figure 3 The y direction is shown in FIG.

[0051] like Figure 4 As shown, a conducting wire 15 is connected to the center of the adsorption plate 11, and the conducting wire 15 is connected to the conductive connection part 14. The current can be transmitted from the conducting wire 15 to the conductive connection part 14, and then the conductive connection part 14 is transmitted to the conductive ejector pin 12, so that the conductive ejector pin 12 has a certain voltage.

[0052] The partition device 1 also includes a moving component 17, which is fixedly connected to the adsorption plate 11, and the moving component 17 is used to control the movement of the adsorption plate 11. The moving component 17 may include a mechanical arm 171, and a clamp may be provided at the end of the mechanical arm 171, and the adsorption plate 11 may be clamped and moved by the clamp, or a suction cup may be provided at the end of the mechanical arm 171, and the adsorption plate 11 may be directly sucked and moved by the suction cup, or a fixing portion may be provided on the adsorption plate 11, and the end of the mechanical arm 171 is directly welded to the fixing portion, and the moving mechanical arm 171 drives the adsorption plate 11 to move. The mechanical arm 171 can be used to move the moving component 17 to control the adsorption plate 11 to move to the top of the display panel 2.

[0053] like Figure 5 As shown, in order to ensure the alignment accuracy between the adsorption plate 11 and the display panel 2, so that the conductive ejector pins 12 are aligned with the common layer 23 between the pixel openings 222, a first alignment mark 16 is provided on the adsorption plate 11, and the first alignment mark 16 is used to align with the second alignment mark 26 on the display panel 2. When the first alignment mark 16 is aligned with the second alignment mark 26, the conductive ejector pins 12 are aligned with the common layer 23 between the pixel openings 222. It should be noted that the adsorption plate 11 can be in any shape, such as a polygon, an ellipse, or a circle.

[0054] The first alignment mark 16 can be set on the edge of the adsorption plate 11, or can be set on the corner of the adsorption plate 11. In order to facilitate the setting of the first alignment mark 16, the shape of the adsorption plate 11 is polygonal, and the first alignment mark 16 is set at each corner of the adsorption plate 11. In order to further ensure the alignment accuracy, one or more first alignment marks 16 can also be set on the edge between the two corners of the adsorption plate 11. The first alignment mark 16 and the second alignment mark 26 can be cross-shaped, or rectangular or triangular.

[0055] like Figure 4 As shown, the partition device 1 further includes a carrier plate 18, which is used to carry the display panel 2 and is disposed on a side of the conductive ejector pins 12 away from the adsorption plate 11, and the carrier plate 18 is spaced apart from the conductive ejector pins 12. The display panel 2 can be fixed at a certain position by the carrier plate 18 and remain unchanged.

[0056] The present invention also provides a partitioning method, which is implemented by the partitioning device 1 provided in any one of the above items. The method may include:

[0057] Step S10, immersing the adsorption plate 11 in the ionic liquid 13, so that the conductive ejector pins 12 are exposed to the ionic liquid 13. Figure 6 shown.

[0058] Step S20, moving the adsorption plate 11 to a side of the common layer 23 away from the pixel definition layer 22, so that the orthographic projection of the conductive ejector pin 12 on the pixel definition layer 22 is located between two adjacent pixel openings 222;

[0059] Step S30, moving the adsorption plate 11 close to the common layer 23, so that the conductive ejector pins 12 and the ionic liquid 13 contact the overlapped portion of the common layer 23 and the pixel definition portion 221;

[0060] Step S40, controlling the conductive pin 12 with the ionic liquid 13 to move on the common layer 23 along the contour of the pixel opening 222 to form a partition groove 24 to partition the common layer 23 between two adjacent pixel openings 222, such as Figure 7 shown.

[0061] The method controls the conductive pin 12 to move on the common layer 23 along the contour of the pixel opening 222 to form a partition groove 24 to partition the common layer 23 between two adjacent pixel openings 222, thereby isolating the connection between adjacent sub-pixels, thereby preventing the carriers of one sub-pixel from leaking laterally to another adjacent sub-pixel, ensuring that the luminescence of the sub-pixel does not reach the expected value.

[0062] The partition method involved in the present invention is described in detail below with reference to specific embodiments.

[0063] like Figure 6 As shown, the adsorption plate 11 is immersed in the ionic liquid 13 in the ionic liquid pool 3, so that a certain amount of ionic liquid 13 is attached to the conductive pin 12; the display panel 2 is fixed to the supporting plate 18, and the adsorption plate 11 is driven by the moving component 17 to move to the side of the common layer 23 away from the pixel definition layer 22, so that the positive projection of the conductive pin 12 on the pixel definition layer 22 is located between two adjacent pixel openings 222.

[0064] like Figure 7 As shown, the moving component 17 drives the adsorption plate 11 to approach the common layer 23, so that the conductive ejector pins 12 and the ionic liquid 13 contact the overlapping portion of the common layer 23 and the pixel definition portion 221, so that the ionic liquid 13 on the conductive ejector pins 12 dissolves the common layer 23 above the pixel definition portion 221. The moving component 17 drives the conductive ejector pins 12 to move on the common layer 23 along the contour of the pixel opening 222, so as to form a partition groove 24 between two adjacent pixel openings 222 to partition the common layer 23.

[0065] like Figure 8As shown, when the conductive ejector pin 12 moves along the outline of the pixel opening 222 along the overlapped portion of the common layer 23 and the pixel definition portion 221, the conductive ejector pin 12 also scrapes off the common layer 23 while dissolving the common layer 23 through the ionic liquid 13, and forms a first groove section 241 on the first common layer 23 through dissolution and scraping. In addition, the second groove section 242 processed by the conductive ejector pin 12 will remain on the pixel definition portion 221. The first groove section 241 and the second groove section 242 form a partition groove 24, which isolates the connection between the sub-pixels, so that the lateral side leakage phenomenon is greatly reduced, the luminous amount of the sub-pixels can reach the expected value, the color of the synthesized light can also reach the expected value, and the display effect of the display panel 2 is enhanced.

[0066] like Fig. 9 As shown, the display panel 2 treated with the conductive ejector pins 12 having the ionic liquid 13 is purged with plasma wind to remove any residual ionic liquid 13. Fig.10 As shown, the adsorption plate 11 with the dissolved substance of the common layer 23 is placed in the aqueous solution in the water pool 4 to clean the residue on the conductive ejector pin 12. Fig.11 As shown, the conductive ejector pin 12 is cleaned by plasma wind blowing.

[0067] The present disclosure also provides a display panel 2. Figure 8 As shown, the display panel 2 may include a pixel definition layer 22 and a light-emitting layer group, the pixel definition layer 22 includes a plurality of pixel definition parts 221, and pixel openings 222 are formed between the pixel definition parts 221; the light-emitting layer group includes a common layer 23, and the common layer 23 covers the pixel definition parts 221 and the pixel openings 222; a partition groove 24 is formed between two adjacent pixel openings 222 by any of the partitioning methods above, and the partition groove 24 partitions the common layer 23. The beneficial effects of the display module can refer to the partitioning method, and the beneficial effects of the partitioning method have been described in detail above, so they will not be repeated here.

[0068] It should be noted that the common layer 23 may include at least one of a hole transport layer, an electron transport layer, a charge generation layer and a cathode.

[0069] The present disclosure also provides a display device, which may include the display panel 2 mentioned in the present disclosure. The specific structure and beneficial effects of the display panel 2 have been described in detail above, so they will not be repeated here.
