[0025] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0026] In an embodiment of the present disclosure, a carrier plate for an evaporating device is provided. The carrier plate has a groove on a surface of a side, for carrying a member to be evaporated, of the carrier plate, wherein a cooler is disposed within the groove, the cooler protruding outward from the carrying surface of the carrier plate, which can reduce the contacting area of the carrier plate with the member to be evaporated, thereby reducing the generation of static electricity.

[0027] FIG. 1 is a schematic plan view of a carrier plate 10 for an evaporating device in accordance with an embodiment of the present disclosure. As shown in FIG. 1, the carrier plate 10 includes a substrate 1, a groove 2 on a surface of a side, for carrying a member to be evaporated (not shown), of the substrate 1, and a cooler 3 disposed within the groove 2. In an exemplary embodiment, the member to be evaporated may be a glass substrate. In an exemplary embodiment, the groove 2 extends continuously in an S-shape, and the groove extends uniformly throughout the carrying surface of the substrate in a zigzag way. It should be noted that the extending shape of the groove 2 can also be designed according to actual needs. In an exemplary embodiment, a depth of the groove 2 is not particularly limited, as long as a bottom surface of the groove 2 has a certain distance from a non-carrying surface of the substrate 1.

[0028] FIG. 2 is a cross-sectional view of the carrier plate 10 taken along line AA of FIG. 1 in accordance with an embodiment of the present disclosure. FIG. 3 is a cross-sectional view of the carrier plate 10 taken along line BB of FIG. 1 in accordance with an embodiment of the present disclosure. It should be noted that the cross-sectional view shown in FIG. 2 is a cross-sectional view taken along a direction perpendicular to the extending direction of the groove, and the cross-sectional view shown in FIG. 3 is a cross-sectional view taken along the extending direction of the groove. For facilitating to illustrate the embodiments of the present disclosure, both FIGS. 2 and 3 show the member to be evaporated 20 disposed opposite the carrying surface of the carrier plate 10. The carrier plate 10 carries the member to be evaporated 20 thereon and serves to cool the member to be evaporated 20.

[0029] As shown in FIGS. 2 and 3, the size of the cooler 3 in the direction from the bottom of the groove 2 toward the outside is not particularly limited, as long as the cooler 3 protrudes outward from the carrying surface of the substrate 1. In an exemplary embodiment, the degree of protrusion is not specifically limited without affecting the flatness and deformation of the member to be evaporated 20, as long as the member to be evaporated 20 can be brought into contact only with the cooler 3 and the contacting area is as small as possible.

[0030] In an exemplary embodiment, a cross-sectional shape of the groove 2 in a direction perpendicular to the extending direction of the groove is a rectangle.

[0031] In an exemplary embodiment, a cross-sectional shape of the cooler 3 in a direction perpendicular to a direction along which the cooler extends is a rectangle or a circle. It can be understood that the cross-sectional shape of the cooler 3 shown in FIG. 2 being a rectangle is merely exemplary.

[0032] In FIG. 2, there is a gap between the cooler 3 and a side wall of the groove 2. In an exemplary embodiment, the size of the gap is not particularly limited, as long as the cooler 3 does not fall from the groove 2.

[0033] In an exemplary embodiment, the cooler 3 may be a cooling tube, wherein the cooling tube is filled with a cooling liquid for cooling the member to be evaporated 20.

[0034] FIG. 4 is a cross-sectional view of the carrier plate 10 taken along line BB of FIG. 1 in accordance with another embodiment of the present disclosure. For facilitating to illustrate another embodiment of the present disclosure, FIG. 4 shows the member to be evaporated 20 disposed opposite to the carrying surface of the carrier plate 10. FIG. 4 differs from FIG. 3 in that an elastic element 4 is disposed between the cooler 3 and the bottom of the groove 2.

[0035] In an exemplary embodiment, the elastic element 4 may be a spring.

[0036] The present disclosure does not specifically limit the length of the elastic member 4 in the maximum compression state and the size of the cooler 3 in a direction from the bottom of the groove 2 toward the outside, as long as the member to be evaporated 20 is closest to the carrier plate 10 and the cooler 3 protrudes outward from the carrying surface of the substrate 1. In an exemplary embodiment, the degree of protrusion is not specifically limited without affecting the flatness and deformation of the member to be evaporated 20, as long as the member to be evaporated 20 can be brought into contact only with the cooler 3 and the contacting area is as small as possible.

[0037] As shown in FIG. 4, when the member to be evaporated 20 being separated from the carrier plate 10, the elastic member 4 provides a downward force F, thereby separating the member to be evaporated 20 from the carrier plate 10, so as to prevent from generating static electricity which may cause that the member to be evaporated 20 may not be separated from the carrier plate 10. In an exemplary embodiment, the member to be evaporated may be separated from the carrier plate either manually or automatically.

[0038] In the embodiment of the present disclosure, the cooler protrudes outward from the carrying surface of the carrier plate, which can reduce the contacting area of the member to be evaporated with the cooler, thereby reducing the generation of static electricity. In addition, the cooler is in direct contact with the member to be evaporated, such that the temperature of the member to be evaporated can be more effectively controlled. Further, an elastic member is disposed between the cooler and the bottom of the groove, so as to provide a downward force to the member to be evaporated when the member to be evaporated being separated from the carrier plate, thereby ensuring that the member to be evaporated cannot be absorbed to the carrier plate due to the reasons such as static electricity, etc.

[0039] In an embodiment of the present disclosure, there is also provided an evaporating device including the above carrier plate. It is possible to reduce the generation of static electricity during the evaporating process.

[0040] The foregoing description of the embodiments has been provided for purpose of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are included within the scope of the disclosure.
