The invention discloses a segment code screen, a preparation method thereof, an automobile instrument panel display device and a display method thereof, and belongs to the field of automobile instrument panel display. The technical problems that the boundary color difference is obvious and the overall visual effect is poor in the actual display effect in the matching process of the segment code screen and the color film are solved. According to the technical scheme, a screen ring, a segment code screen, a color diaphragm, a printed board support, a printed board and an instrument bottom shell are sequentially arranged from top to bottom, the segment code screen and the color diaphragm are the same in size, an LED light source is arranged on the printed board, and a gradual change ink layer printed through UV is machined at the window boundary of the back face of the segment code screen. The ink jet amount of the gradually-changed ink layer in the direction from the inner ring to the outer ring of the automobile instrument panel is gradually reduced. Through the UV-printed gradient ink layer, color gradient at the boundary of the code screen window after the automobile instrument panel is lightened is realized, and color transition is uniform. The method is used for automobile instrument panel segment code screen display.

    一种段码屏及其制备方法、汽车仪表盘显示装置及其显示方法,属于汽车仪表盘显示领域。本发明解决了段码屏在和彩色膜片配合过程中的实际显示效果存在边界色差明显,整体视觉效果不佳的技术问题。本发明的技术方案由上到下依次设置的屏圈、段码屏、彩色膜片、印制板支架、印制板和仪表底壳,段码屏和彩色膜片的大小尺寸相同,所述印制板上设置有LED光源,段码屏的背面开窗边界处加工有通过UV打印的渐变油墨层,渐变油墨层沿汽车仪表盘的内圈至外圈方向的喷墨量逐渐减少。通过UV打印的渐变油墨层实现汽车仪表盘点亮后段码屏开窗边界处的颜色渐变并且颜色过渡均匀。本发明用于汽车仪表盘段码屏显示。
