Abstract: A temperature regulating valve and a thermal management system provided with the temperature regulating valve are provided. The temperature regulating valve includes a filling state and a first working state, and a thermodynamic element is impelled to not abut against a first valve seat by means of providing a hot melt in an end cover of the temperature regulating valve. When a first valve port is in an open state, at said time the temperature regulating valve is installed in the thermal management system, and since the first valve port is in the open state, lubricating oil may then flow into a heat exchange device by means of a first interface channel, the first valve port, and a second interface channel during a process of filling the lubricating oil.

Abstract: A display substrate is provided. The display substrate has a display region and a non-display region disposed around the display region and the display substrate includes a base substrate and a barrier structure disposed on a side of the base substrate. The barrier structure is disposed in the non-display region, and the barrier structure includes a metal structure and a protective layer which are arranged on the substrate in sequence and the protective layer covers the metal structure.

Abstract: The present disclosure provides a display panel, a manufacturing method thereof and a display device. The display panel includes a base substrate, a TFT array, a pixel definition layer, and a plurality of light-emitting units. The display panel further includes a plurality of spacers arranged on a surface of the pixel definition layer away from the base substrate, the plurality of spacers is formed integrally with the pixel definition layer, a surface of each spacer away from the base substrate includes a first portion and a second portion, a distance between the second portion and the base substrate is smaller than a distance between the first portion and the base substrate, and a ratio of a sum of areas of the first portions of the plurality of spacers to an area of a display region of the display panel is not smaller than a preset threshold.
