Abstract: A hydraulic circuit for opening and closing a mould of an injection moulding machine, and an injection moulding machine system includes an operating oil cylinder and a proportional valve; by means of adjusting the proportional valve to different operating states, the operating oil cylinder can be controlled to execute different actions, so as to control mould opening, mould closing and mould differential closing of the injection moulding machine. By means of a differential proportional valve with a flow regeneration function, the present invention can effectively increase control precision in a mould opening and closing process, reduce energy consumption and the number of parts of a system, and save on space taken up by the system, with complete functions of mould opening and closing also being realizable.

Abstract: The present invention discloses a method of displaying on an electronic device and an electronic device. The method is applied in an electronic device with a display unit, which includes: acquiring a first environment light parameter of an environment around the electronic device, wherein, the first environment light parameter comprises at least a second color temperature value of the environment; determining a first display parameter of the display unit according to the first environment light parameter; and displaying on the display unit with the first display parameter.

Abstract: An information processing method and an electronic device are provided. In the method, when an event to be processed is received by an electronic device, a control instruction is generated. The electronic device generates prompting information and controls a display unit of the electronic device to be in a dark state in response to the control instruction. Finally the electronic device outputs the generated prompting information by a first prompting unit in the electronic device.
