Abstract

The invention discloses an automatic heating control circuit, a display and a heating method. The automatic heating control circuit includes: a temperature sensor for detecting temperature data; a comparator configured to be connected to the temperature sensor to Comparing the temperature data with the first preset data to obtain a first opening signal or a first closing signal; a control unit configured to be connected to the temperature sensor to process the temperature data to obtain a second opening signal Or the second shutdown signal; a heating circuit configured to be respectively connected to the comparator and the control unit to determine whether heating is performed by the heater. The automatic heating control circuit overcomes the problem that the display in the prior art cannot work in a low temperature environment, and realizes the automatic heating system of the product.

Description

technical field [0001] The invention relates to the heating field, in particular to an automatic heating control circuit, a display and a heating method. Background technique [0002] At present, the airborne liquid crystal display module needs to meet the corresponding environmental requirements in the actual application process, and the low temperature can reach -45°C. When the liquid crystal works in a low temperature environment, the viscosity of the liquid crystal increases, the electro-optic effect weakens or disappears and cannot work normally. At this time, the overall brightness of the LCD screen decreases, the color fades, the contrast decreases rapidly, and the response time for image loading is prolonged. When the temperature drops further (below -30°C), the signal disappears, and the LCD screen becomes normally white. Due to the liquid crystal molecules Due to its special physical characteristics, when the display is activated at low temperature, the information...
