description The invention discloses an automatic authoring method of a high-way liquid crystal display, comprising the following steps: (1) detecting the brightness value of a liquid crystal display screen by using a light sensor when the liquid crystal display screen is totally white or black, transmitting the brightness value to an SCM, and calculating the contrast value by using the SCM according to the obtained brightness value; (2) adjusting the output voltage of a liquid crystal driving chip, repeating the step (1) to obtain a plurality of groups of contrast value, and comparing to obtain the maximum contrast value; and (3) and authoring by using the output voltage of the liquid crystal driving chip, which corresponds to the maximum contrast value, if the maximum contrast value is more than a specifications value. Due to the adoption of the automatic authoring method of the high-way liquid crystal display, the output voltage of the liquid crystal driving chip, which can ensure that the liquid crystal display screen
