A circuit board includes: a power supply wiring board that includes a power supply circuit that outputs the power supply voltage, and a first power supply line and a second power supply line which are connected with the power supply circuit; a first wiring board that includes a first line; a second wiring board that includes a second line; a first cable that includes a first conductor that connects the first power supply line and the first line; a second cable that includes a second conductor that connects the second power supply line and the second line; and a short-circuit conductor that short-circuits the first line and the second line. An electrical length of a route from the power supply circuit to the first wiring board is shorter than an electrical length of a route from the power supply circuit to the second wiring board.

Circuit board and display device

A display device includes: a display panel; a main wiring board; a first wiring board that includes a first feedback line; and a first cable that is removably coupled to the main wiring board and the first wiring board. The main wiring board includes: a first output line; a first input line; a first circuit (a power supply circuit) that outputs a first voltage to the first output line; and a control circuit that is connected with the first input line. The first cable includes: a first forward conductor that directly or indirectly connects the first output line and the first feedback line; and a first return conductor that directly or indirectly connects the first input line and the first feedback line. The control circuit determines whether the first voltage is input, and when an input of the first voltage is determined, starts a display on the display panel.

Display device and method for checking display device

A flexible wiring board (a first wiring board) includes: an insulating substrate which is flexible; a first terminal which is conductive and is disposed on the insulating substrate; a second terminal which is conductive and is disposed on the insulating substrate; and a no-connection (NC) terminal which is conductive and is disposed on the insulating substrate between the first terminal and the second terminal. The first terminal, the NC terminal, and the second terminal are arranged at a uniform pitch in an arranging direction that is predetermined, and a width of the NC terminal in the arranging direction is smaller than a width of the first terminal in the arranging direction and a width of the second terminal in the arranging direction.

Flexible wiring board and display device

A first wiring plate is a flexible wiring plate to be directly connected to a display panel, and includes a first connector. The first connector is directly connected to a second connector included in a second wiring plate to be directly connected to the display panel.

Flexible wiring plate, flexible wiring plate pair, and display device

The present invention makes it possible to cope with a plurality of standardized transient operation modes in a method for adapting the engine transient characteristic to a required performance targets and a system therefore. When there are a plurality of prescribed standardized transient operation modes, transient testing is conducted in a single transient operation mode that covers changing patterns of control values of control factors of the plurality of transient operation modes. Only data in a data distribution range to be focused on is captured to create a transient engine model.
