A graphic meter mounted on a vehicle is provided with a display unit of an image display type, which displays an instrument of the vehicle, an acquisition unit which acquires a course information indicating a course of the vehicle and a control unit which is connected to the display unit and the acquisition unit. The control unit controls a display content of a highlight which is displayed in the instrument of the display unit based on a position of a virtual light source located in a virtual space projected on a plane surface. The control unit identifies a change of the course of the vehicle based on the course information acquired by the acquisition unit, and causes the virtual light source to move, according to a result of the identification.

A method of and a system for presenting an operating status of an aircraft engine. The method comprises accessing a first indication indicative of a position of an aircraft engine start switch and accessing a second indication indicative of an aircraft engine start operating mode, the second indication having been generated based on an analysis of a parameter associated with an operating condition of the aircraft engine. The method, upon determining that the position of the aircraft engine start switch is an on position and the aircraft engine start operating mode is a healthy start causes the display of a visual indication indicative of the healthy start. The method upon determining that the position of the aircraft engine start switch is an on position and the aircraft engine start operating mode is an abnormal start causes the display of a visual indication indicative of the abnormal start.

A trip gauge for a vehicle information display may convey vehicle trip information and vehicle range information graphically to assist drivers in qualitatively visualizing and determining whether they can successfully make it to their destination before an on-board energy source is depleted. The trip gauge may include indicators corresponding to the relative locations of the vehicle, the destination, and a projected zero charge location associated with the vehicle's range or distance to empty value. Moreover, the positions of the indicators relative to one another may indicate whether the excess energy is available for the vehicle to reach the destination or whether the energy available is insufficient. Accordingly, drivers may be either reassured that they are expected to reach their destination successfully or warned if they are not so the drivers can modify their driving behavior or change their destination.

A display device includes a dial, a substrate, a plurality of light source parts, and a transmittance adjustment part. The transmittance adjustment part has a low transmittance part in which a transmittance of light is lower than a predetermined value and a high transmittance part in which a transmittance of light is higher than that of the low transmittance part, and adjusts a transmittance of light from the plurality of light source parts. Each of the light source parts includes a first light source and a second light source having different light-emission colors to be alternately switched on lighting. The low transmittance part is arranged within an area corresponding to the plurality of light source parts. The high transmittance part is located based on a midpoint position where the distance from the adjacent light source parts is equal in the circumferential direction between the light source parts.
