According to the brightness control method of the vehicle-mounted display screen and the vehicle-mounted display screen, by determining the riding state of a driver at a driving position, when the driver exists at the driving position, face recognition is executed to obtain the spatial relative positions of the eyes of the driver relative to the vehicle-mounted display screen; calculating an incident space corresponding to light reflected from the vehicle-mounted display screen to the eyes of the driver according to the spatial relative position, obtaining incident light intensity distribution of the incident space, calculating reflected light intensity distribution of the vehicle-mounted display screen according to the incident light intensity distribution, constructing a reflected light intensity contour line according to the reflected light intensity distribution, and obtaining a reflected light intensity contour line of the vehicle-mounted display screen; calculating a reflection intensity change gradient value corresponding to each pixel of the vehicle-mounted display screen according to the distribution of the reflection intensity contour lines, determining a pixel set of which the reflection intensity change gradient value of the vehicle-mounted display screen is greater than a first threshold value as a transition area, and controlling the pixel brightness of the transition area to be matched with the reflection intensity change gradient value, the problem that the content displayed by the vehicle-mounted display screen is not clear is solved.

    本发明提出一种车载显示屏的亮度控制方法及车载显示屏,通过确定驾驶位的驾驶员乘坐状态,当驾驶位存在驾驶员时,执行人脸识别以获取驾驶员双眼相对于车载显示屏的空间相对位置,根据空间相对位置计算从车载显示屏反射至驾驶员双眼的光线对应的入射空间,获取入射空间的入射光线强度分布,根据入射光线强度分布计算车载显示屏的反射光线强度分布,根据反射光线强度分布构建反光强度等高线,根据反光强度等高线的分布计算车载显示屏每一个像素对应的反光强度变化梯度值,将车载显示屏的反光强度变化梯度值大于第一阈值的像素集合确定为过渡区域,控制过渡区域的像素亮度以匹配反光强度变化梯度值,克服车载显示屏显示内容不清晰的问题。
