Abstract

The invention discloses a parking lot information display board capable of adjusting brightness and a manufacturing method thereof. Structures of electrochromic devices and manufacturing technology are improved, and the display board is characterized by self-energizing, so that the novel parking lot information display board which is short in response time, prolonged in life, and good in freezing tolerance performance is manufactured. The method is simple and easy in operation, and can be easily used in industrialized production.

Description

technical field [0001] The invention belongs to the traffic field, and more specifically relates to a parking lot information display board capable of automatically adjusting brightness and a manufacturing method thereof. Background technique [0002] The information display board is a plate-shaped medium used for information release and display. Specifically, the parking lot information display board can be used to display information such as the location of the parking lot, the number of vacancies, and the charging standard. Display cards generally have paper, metal and so on. [0003] However, under outdoor conditions, general parking lot display signs are not sensitive to light. Due to the influence of sunlight, etc., problems such as unclear display information will be caused, resulting in poor reading information for users. Contents of the invention [0004] Aiming at the problems existing in the background technology, the present invention provides a parking lot in...
