The invention relates to a full-liquid-crystal combination instrument with an automatic anti-dazzling function. The problem that at present, the cost for solving the dazzling problem is high is solved. Comprising a phototriode, an AD converter, a main controller, a DA converter, a liquid crystal screen controller and a liquid crystal screen, when light is irradiated on a P-N structure of the phototriode, the phototriode absorbs light energy, converts the light energy into electric energy and transmits the electric energy to the AD converter, and the AD converter converts a voltage signal of the phototriode into a digital signal and transmits the digital signal to the main controller; the main controller sends a digital signal to the DA converter after calculating illumination intensity and comparing system time, the DA converter converts the digital signal transmitted by the main controller into a voltage signal and transmits the voltage signal to the liquid crystal screen controller, and the liquid crystal screen controller controls the liquid crystal screen to change light transmittance after receiving the voltage signal so as to reduce reflectivity and absorb strong light. And hard light reflection is reduced, so that the anti-dazzling purpose is achieved. According to the invention, the development cost can be reduced while the anti-dazzling purpose is achieved.
本发明涉及一种带有自动防眩目功能的全液晶组合仪表,解决了目前解决炫目问题费用高昂的问题。包括光敏三极管、AD转换器、主控制器、DA转换器、液晶屏控制器和液晶屏,当光照在光敏三极管P‑N结构上时,光敏三级管吸收光能并转变为电能传输给AD转换器,通过AD转换器将光敏三极管的电压信号转换为数字信号传输给主控制器,主控制器经过计算光照强度以及系统时间的比对后,发出数字信号给DA转换器,DA转换器将主控制器传输的数字信号转换为电压信号传输给液晶屏控制器,液晶屏控制器收到电压信号后进而控制液晶屏改变透光率从而降低反射率吸收强光,削减强光反射进而达到防眩目的目的。本发明在达到防眩目目的的同时可降低开发成本。
