[0033] (Example)

[0034] Figure 1 is a view schematically showing a time-sensing platform according to an embodiment of the present disclosure. Figure 2 is a view of a pallet in a aging platform according to an embodiment of the present disclosure. Figure 3 is a view showing the relative positions of a pressing rod (or a pressure rod) during an aging process in an aging platform according to an embodiment of the present disclosure. Figure 4 It is along Figure 3 A view taken along line I-I'.

[0035] refer to Figures 1 to 4 According to an embodiment of the present disclosure, the aging platform AP may include (or contain) a base plate 100, a driving unit 200, and a plurality of trays 300. The base plate 100 may support the driving unit 200 and the trays 300. The plurality of trays 300 may be stacked (laminated) on the driving unit 200. The driving unit 200 may include a circuit for aging treatment. For example, a power supply unit that applies a power supply voltage to each tray 300 and a controller that controls the display panel P mounted on each tray 300 may be provided in the driving unit 200.

[0036] Each of the plurality of trays 300 may include a seating portion 310, a circuit portion 320, and at least one pressing rod 330. A display panel P as an object of aging treatment may be mounted on the seating portion 310. The circuit portion 320 may transmit a signal for aging treatment of the display panel P mounted on the seating portion 310. The pressing rod 330 may be provided on the seating portion 310. The display panel P may be a device (means) for providing an image to a user. For example, the display panel P may be a liquid crystal panel or an OLED panel.

[0037] The placement portion 310 may support the display panel P during the aging process. For example, the placement portion 310 may include a pad that supports the lower surface of the display panel P. A space for heat movement may be provided below the placement portion 310. Therefore, in the aging platform AP according to an embodiment of the present disclosure, damage to the display panel P due to heat may be prevented.

[0038] The circuit part 320 may transmit the power supply voltage and the aging signal applied from the driving unit 200 to the display panel P. The circuit part 320 of each tray 300 may be individually connected to the driving unit 200. For example, a signal transmission unit 400 for electrically connecting the driving unit 200 to the circuit part 320 of each tray 300 may be provided on a side of each tray 300.

[0039] The pressing bar 330 can press the upper surface of the display panel P mounted on the placement portion 310 during the aging treatment. The pressing bar 330 can move in the horizontal direction. Therefore, in the aging platform AP according to the embodiment of the present disclosure, the process of installing the display panel P on the placement portion 310 of each tray 300 can be simplified. For example, the pressing bar 330 can be moved to the display panel P after the display panel P is mounted on the placement portion 310. Therefore, in the aging platform AP according to the embodiment of the present disclosure, damage to the display panel P during the movement process for the aging treatment can be prevented.

[0040] The pressing rod 330 may include a pressing body 331 and a plurality of protrusions 332 protruding from the pressing body 331. The pressing body 331 may extend in a direction that may be referred to as an extension direction. For example, the display panel P may have a rectangular shape in which the length in the first direction is shorter than the length in the second direction perpendicular to the first direction, and the pressing body 331 may extend in the second direction. The placement portion 310 may have a shape corresponding to the display panel P. For example, the length of the placement portion 310 in the first direction may be shorter than the length of the placement portion 310 in the second direction. For example, in the aging platform AP according to an embodiment of the present disclosure, the pressing rod 330 of each tray 300 may extend in the long axis direction of the display panel P.

[0041] Each of the plurality of protrusions 332 may protrude from the pressing body 331 in a direction toward the seating portion 310. For example, an end region of each protrusion 332 facing the seating portion 310 may be in direct contact with an upper surface of the display panel P mounted on the seating portion 310. Therefore, in the aging platform AP according to the embodiment of the present disclosure, the polarizer attached to the surface of the display panel P may be prevented from bending during the aging treatment. Moreover, in the aging platform AP according to the embodiment of the present disclosure, the movement of the display panel P during the movement may be prevented. Therefore, in the aging platform AP according to the embodiment of the present disclosure, the display panel P may be prevented from being damaged due to the aging treatment.

[0042] An end region of each protrusion 332 facing the seating portion 310 may have a curved surface. Therefore, in the aging platform AP according to an embodiment of the present disclosure, damage to the surface of the display panel P due to the pressing of the pressing bar 330 may be minimized.

[0043] The plurality of protrusions 332 may be arranged side by side in the extension direction of the pressing body 331. For example, the distance between adjacent protrusions 332 may be constant. Therefore, in the aging platform AP according to the embodiment of the present disclosure, the surface of the display panel P may be uniformly pressed by the plurality of protrusions 332.

[0044] Each of the plurality of protrusions 332 may be spaced apart from an adjacent protrusion 332. For example, a plurality of particle collecting holes Cg may be formed between the plurality of protrusions 332. Therefore, in the aging platform AP according to the embodiment of the present disclosure, particles located on the surface of the pressing body 300 may be moved to one of the plurality of particle collecting holes Cg. For example, in the aging platform AP according to the embodiment of the present disclosure, the upper surface of the display panel P will not be pressed by particles located on the surface of the pressing rod 330 during the aging treatment. Therefore, in the aging platform AP according to the embodiment of the present disclosure, damage to the surface of the display panel P due to the aging treatment may be prevented.

[0045] Therefore, in the aging platform AP according to the embodiment of the present disclosure, each tray 300 may include a placement portion 310 on which a display panel P as an object of aging treatment is mounted, and at least one pressing rod 330 provided on the placement portion 310, wherein the particle collection hole Cg may be formed on the surface of the pressing rod 330 facing the placement portion 310 by the plurality of protrusions 332. Therefore, in the aging platform AP according to the embodiment of the present disclosure, damage to the surface of the display panel P due to the aging treatment may be prevented. Therefore, in the aging platform AP according to the embodiment of the present disclosure, the processing efficiency may be improved.

[0046] Figure 5 , Figure 6 , Fig. 7A and Figure 7B is a view showing a time-sensing platform according to another embodiment of the present disclosure.

[0047] In the aging platform according to another embodiment of the present disclosure, the plurality of protrusions 332 of the pressing rod 330 may have various shapes. For example, in the aging platform according to another embodiment of the present disclosure, each protrusion 332 of the pressing rod 330 may include three regions with different widths, specifically, a first region 332a, a second region 332b, and a third region 332c, such as Figure 5 As shown. The first area 332a of each protrusion 332 can be arranged near the placement portion 310. The second area 332b and the third area 332c of each protrusion 332 can be arranged sequentially (in sequence) between the first area 332a of the corresponding protrusion 332 and the pressing body 331. The width of each protrusion 332 can increase as the distance from the pressing body 331 increases. For example, the width of the second area 332b can be greater than the width of the third area 332c, and the width of the first area 332a can be greater than the width of the second area 332b. Therefore, in the aging platform according to another embodiment of the present disclosure, the width of each particle collection hole Cg can increase toward the pressing body 331. For example, in the aging platform according to another embodiment of the present disclosure, during the aging process, the particles moved into the particle collection hole Cg may be difficult to be reintroduced between the display panel P and the plurality of protrusions 332. Therefore, in the aging platform according to another embodiment of the present disclosure, damage to the surface of the display panel P due to particles may be significantly reduced during the aging process.

[0048] In the aging platform according to another embodiment of the present disclosure, each protrusion 332 of the pressing rod 330 may be made of two regions (specifically, a first region 332a and a second region 332b) having different widths. For example, in the aging platform according to another embodiment of the present disclosure, each protrusion 332 of the pressing rod 330 may be made of a first region 332a and a second region 332b having a width smaller than that of the first region 332a, such as Figure 6 The second region 332b of each protrusion 332 may be disposed between the first region 332a of the corresponding protrusion 332 and the pressing body 331. Therefore, in the aging platform according to another embodiment of the present disclosure, the degree of freedom of the shape of each protrusion 332 may be increased.

[0049] In an aging platform according to another embodiment of the present disclosure, each of the plurality of trays 300 may include a magnetic element 340 disposed between the second regions 332b of adjacent protrusions 332. For example, the magnetic element 340 may surround (enclose) a portion of the second region 332b of each protrusion 332. Therefore, in an aging platform according to another embodiment of the present disclosure, during the aging treatment, the conductive particles may be collected in the particle collection hole Cg by the magnetic element 340. The conductive particles may include metal. Therefore, in an aging platform according to another embodiment of the present disclosure, damage to the surface of the display panel P due to relatively hard metal particles may be prevented.

[0050] The aging platform AP according to an embodiment of the present disclosure is described as a pressing rod 330 including a plurality of protrusions 332 protruding from a pressing body 331. However, in an aging platform according to another embodiment of the present disclosure, the pressing rod 330 of each tray 300 may have various shapes to provide a space for collecting particles. For example, in an aging platform according to another embodiment of the present disclosure, each of the plurality of trays 300 may include a pressing body 331 extending in a direction that may be referred to as an extension direction, and a cover element 334 surrounding a portion of the pressing body 331, wherein a plurality of particle collection holes 334h may be provided at a surface of the cover element 334 facing the placement portion 310, such as Fig. 7A and Figure 7B As shown. Therefore, in the aging platform according to another embodiment of the present disclosure, during the aging process, particles can be collected in the particle collection hole 334h. Therefore, in the aging platform according to another embodiment of the present disclosure, a space for collecting particles can be formed in various ways.

[0051] In the aging platform according to another embodiment of the present disclosure, the magnetic element 340 may be disposed between the pressing body 331 and the cover element 334. For example, in the aging platform according to another embodiment of the present disclosure, a portion of the magnetic element 340 may be exposed through the particle collection hole 334h of the cover element 334. Therefore, in the aging platform according to another embodiment of the present disclosure, the degree of freedom of the method of forming a space capable of collecting various particles may be increased.

[0052] As a result, the aging platform according to the embodiment of the present disclosure may include a plurality of trays, wherein each of the plurality of trays may include a placement portion on which a display panel is mounted, and at least one pressing rod disposed on the placement portion, wherein the pressing rod may include a protrusion protruding toward the placement portion or a hole disposed at the surface of the pressing rod facing the placement portion. Therefore, in the aging platform according to the embodiment of the present disclosure, particles located on the surface of the pressing rod will not press the surface of the display panel. Therefore, in the aging platform according to the embodiment of the present disclosure, damage to the display panel caused by the aging treatment can be minimized.
