    • A display device for vehicle includes an LCD panel that has a first pixel region and a second pixel region. The display controller portion displays a meter image on the first pixel region at a regular time and a specific time, and displays an outside image on the second pixel region at the specific time. The display controller portion controls a gradient ratio of pixel in the first pixel region as a meter image gradient ratio, and controls a gradient ratio of pixel in the second pixel region as an outside image gradient ratio. The display controller portion switches and performs a first mode and a second mode. In the first mode, the display controller portion keeps both the meter image gradient ratio and the outside image gradient ratio to the maximum ratio R1max and R2max, and varies a source luminance of a light source according to an adjust value which is in a side brighter than a reference value Cb. In the second mode, the display controller portion keeps the source luminance of the light source at the minimum source luminance Lmin, varies the meter image gradient ratio according to an adjust value which is in a side darker than the reference value Cb, and keeps the outside image gradient ratio at the maximum ratio R2max. As a result, the multiple images in which the display objectives differ can be appropriately displayed to attain each objective.
    • 车辆用显示装置包括具有第一像素区域和第二像素区域的LCD面板。 显示控制器部分在规定时间和特定时间在第一像素区域上显示仪表图像,并且在特定时间在第二像素区域上显示外部图像。 显示控制器部分控制第一像素区域中的像素的梯度比作为度量图像梯度比,并且将第二像素区域中的像素的梯度比控制为外部图像梯度比。 显示控制器部分切换并执行第一模式和第二模式。 在第一模式中,显示控制器部分将仪表图像梯度比和外部图像梯度比都保持为最大比率R1max和R2max,并且根据位于更亮的调整值来改变光源的源亮度 比参考值Cb。 在第二模式中,显示控制器部分将光源的亮度保持在最小源亮度Lmin,根据位于比基准值Cb更暗的调整值改变仪表图像的梯度比,并保持 外部图像梯度比在最大比R2max。 结果,可以适当地显示其中显示目标不同的多个图像以实现每个目标。
