The invention discloses an automatic adjustment type sun shield. The sun shield comprises a TFT liquid crystal display screen and an outer shell at the top of the TFT liquid crystal display screen; the TFT liquid crystal display screen is provided with bottom glass; a photosensitive window is formed in the side, facing a car window, of the outer shell; an outward extension part is arranged at theend, located in the outer shell, of the bottom glass of the liquid crystal display screen; a thin film transistor is installed on the extension part; and the thin film transistor is opposite to the photosensitive window. The sun shield is simple in structure, the thin film transistor on the extension part of the bottom glass, at one end in the outer shell, of the TFT liquid crystal display screenchanges along with the change of illumination intensity, so that the function of a photosensitive element is achieved; the thin film transistor is different from the TFT liquid crystal display screenin that only a liquid crystal layer and a shading layer are lacked; and therefore, in the process of product production and processing, the thin film transistor serving as the photosensitive element and the TFT liquid crystal display screen can be synchronously processed and formed, an additional photosensitive element does not need to be arranged, the performance is stable, the processing and installation process is simple, and the cost is low.

    本发明公开了一种自动调节式遮阳板,包括TFT液晶显示屏和TFT液晶显示屏顶部的外壳,所述TFT液晶显示屏有底面玻璃,外壳面向车窗的一侧设置有感光窗口,液晶显示屏的底面玻璃在位于外壳内的一端有向外延伸部,在延伸部上安装薄膜晶体管,所述薄膜晶体管与感光窗口相对。本发明结构简单,TFT液晶显示屏位于外壳内一端的底面玻璃的延伸部上的薄膜晶体管因其电流随光照强度变化而变化,使其具备了感光元件的功能,而由于薄膜晶体管与TFT液晶显示屏的区别仅在于缺少液晶层和遮光层,因此产品生产加工过程中,作为感光元件的薄膜晶体管与TFT液晶显示屏可同步加工形成,其不需额外设置感光元件,性能稳定,加工及安装工艺简单,成本较低。
