Abstract: Disclosed is a trolley, including: a trolley body, comprising a first support plate, and a second support plate perpendicular to the first support plate and fixedly defined on the upper surface of the first support plate; a plurality of carrying platforms, being perpendicular to the second support plate and symmetrically defined on two sides of the second support plate, the carrying platforms located on the same side of the second support plate being arranged in a row and equally spaced, to allow one end of the display panel to abut against the carrying platform, and the other end abut against the second support plate, for the display panel to be placed obliquely. Disclosed are also an aging test apparatus and system.

Abstract: Disclosed are a high-temperature testing device, including a trolley, a furnace and a door body. The trolley includes a base and a display panel placing area defined at the base. The base includes a support table and a protruding block formed on an upper surface of and perpendicular to the support table; the display panel placing area is defined on the protruding block. A power supplier and a signal generator are both defined on the support table. A cavity is formed in the furnace body to match and receive the trolley. A first heat insulating plate and a second heat insulating plate are respectively defined on opposite inner walls at two sides of the furnace body. A gap is defined between opposite end portions of the first heat insulating plate and the second heat insulating plate, for the protruding block to pass through.
