Description

TRAY The present invention relates to a tray capable of transporting or storing display panels or electronic components. More specifically, it relates to a technology for stacking multiple trays loaded with display panels or electronic components. Trays are used to transport or store products at manufacturing sites for display panels or electronic components. Conventional trays had internal partitions, which meant that only products matching the size and shape could be loaded. Unlike the previous design, the internal partitions of the tray were removed. Consequently, the size and weight of the display panels loaded onto the tray increased. Additionally, when multiple trays were stacked, the upper tray warped due to the load. As the upper tray warped, it came into contact with the trays and display panels stacked below, causing defects in the display panels. FIG. 1 is an exemplary perspective view showing multiple trays stacked according to one embodiment of the present invention. FIG. 2 is an exemplary perspective view of one of the trays of FIG. 1. Figure 3 illustrates the plan view of Figure 2 as an example. FIG. 4a illustrates an exemplary cross-section of a tray cut along I-I' of FIG. 2. FIG. 4b illustrates an exemplary cross-section of a tray cut along II-II' of FIG. 2. Figure 5 illustrates an exemplary cross-section of multiple trays of Figure 4a stacked together. FIG. 6 shows a shape in which a display panel is placed on a tray according to an embodiment of the present invention. This is an example of a city. Figures 7a to 7c illustrate exemplary simulations of the load received by the center of the tray under different conditions. FIG. 8 is an exemplary perspective view of a tray according to another embodiment of the present invention. FIG. 9 is an exemplary perspective view of a tray according to another embodiment of the present invention. FIG. 10 is an exemplary perspective view of a tray according to another embodiment of the present invention. Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the proportions and dimensions of the components are exaggerated for the effective illustration of the technical content. "And/or" includes all one or more combinations that the associated components may define. Terms such as "include" are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. FIG. 1 is an exemplary perspective view of a stack of trays (TY) according to one embodiment of the present invention. FIG. 2 is an exemplary perspective view of one of the trays (TY) of FIG. 1. In this specification, a first direction (DR1), a second direction (DR2), and a third direction (DR3) are illustrated. According to one embodiment of the present invention, a display panel and an electronic device may be disposed on a surface formed by the first direction (DR1) and the second direction (DR2). However, the first to third directions (DR1, DR2, DR3) are arbitrarily set, and the indicated direction may be changed as needed. A tray (TY) may be a device for transporting display panels or electronic components. For example, the electronic components placed on the tray (TY) may be components mounted on at least one electronic device among a monitor, television, smartphone, navigation system, terminal mounted in an automobile, or tablet PC. Additionally, multiple trays (TY) may be stacked. Therefore, the tray (TY) can load a large quantity of display panels or electronic components to increase transport efficiency. The tray (TY) may include plastic materials. For example, the plastic materials may include polyethylene (PE), polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), polyamides (PA), polyester (PES), polyvinyl chloride (PVC), polyurethanes (PU), polycarbonate (PC), or polyvinylidene chloride (PVDC), etc. However, it is not limited thereto, and the materials included in the tray (TY) may be changed as necessary. Referring to FIGS. 1 and 2, the tray (TY) may include a floor member (FL), a plurality of first edge members (EDG1), a plurality of second edge members (EDG2), and a plurality of support members (SPM1 to SPM6). The floor member (FL) may have a predetermined curvature. This will be explained in Fig. 4, which will be described later. Each of the plurality of first edge members (EDG1) is positioned at the first outer edge of the floor member (FL) and may extend along the first direction (DR1). Here, being positioned at the first outer edge may mean that one side of each of the plurality of first edge members (EDG1) is in contact with one side of the floor member (FL). Each of the plurality of second edge members (EDG2) is positioned at a second outer edge diff
