PROBLEM TO BE SOLVED: To conduct display to indicate a direction by gradation using brightness of an LED in a peripheral visual area for a driver. SOLUTION: A display controller 100 increases current values applied to a right-sided LED 112b of a light guide tube 111a provided along an upper side of a shielding glass 301, and a right-sided LED 112d of a light guide tube 111b provided along a lower side of the shielding glass 301, when receiving a control signal for indicating a right turn from a navigation system. As a result thereof, the right-sided LED 112b and LED 112d are illuminated more brightly than left-sided LED 112a and LED 112c. The display controller 100 increases current values applied to the LED 112a provided in the left side of the light guide tube 111a, and the LED 112c provided in the left side of the light guide tube 111b, when receiving a control signal for indicating a left turn. As a result thereof, the left-sided LED 112a and LED 112c are illuminated more brightly than the right-sided LED 112b and LED 112d. |
