Patent number: 10071631Abstract: An automatic two-wheeled vehicle display device is such that, while warning information is being displayed in a second display region, a CPU changes a background color gradation of the second display region to a first gradation (for example, white) for a first setting period t1, gradually increases backlight luminosity to reach a maximum value (100%) in a third setting period t3 that is shorter than the first setting period t1, and maintains the backlight luminosity at the maximum value (t1=t3+t4) for a fourth setting period t4. Subsequently, the CPU changes the background color gradation of the second display region to a second gradation (for example, black) for a second setting period t2, and adjusts the backlight luminosity to a luminosity the same as that in a normal mode (for example, 20%).Type: GrantFiled: August 8, 2017Date of Patent: September 11, 2018Assignee: Mitsubishi Electric CorporationInventors: Hiroshi Aizawa, Hiroyuki Ono
