Problems solved by technology

However, in the actual application process, the user cannot know the dew point temperature of the front surface of the ITO glass, and cannot reasonably determine the timing to turn on the heating. Often, the heating is turned on after condensation is formed on the display screen, or when condensation is impossible, Manually turn on the heating, resulting in waste of electricity

Abstract

The invention discloses an automatic heating and defogging device for a display screen. The automatic heating and defogging device comprises a heating film, a heating film temperature sensor, a temperature and humidity sensor and a controller. The temperature and humidity sensor can calculate temperature of a dew point; the controller can calculate defogging temperature, so as to realize automaticdefogging. The invention innovatively provides a method for calculating the defogging temperature according to the temperature of the dew point, so that an automatic defogging function can be realized. The defogging energy consumption can be avoided, and precious energy is saved. The automatic heating and defogging device for the display screen is concise in structure, obvious in defogging effectand easy to popularize and implement. No manual operation is needed. The safety of aviation work is improved.

Description

technical field [0001] The invention relates to defogging of a display screen, in particular to an automatic heating and defogging device for a display screen and a defogging method, belonging to the technical field of supporting equipment and methods for a display screen. Background technique [0002] There are two types of anti-fogging or defogging of display screens that are common on the market: one is to use fans and heating wires to blow hot air on the surface of the display screen, and dry the fog or condensed water vapor on the surface of the display screen through hot air. However, in actual application, the display screen usually requires a certain sealing performance to prevent the entry of foreign matter, sand and water vapor, and then damage the internal circuit board or other components. However, this method of blowing and heating leads to the need to reserve an air outlet for the display screen, which destroys the airtightness. [0003] The other is to use IT...
