Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the present embodiment.
In this embodiment, as shown in fig. 1-2, a low temperature self-heating's liquid crystal display module, include circuit board 1 and locate LCD display module 2 on the circuit board, LCD display module 2 is equipped with the heating part, the heating part includes temperature control inductor, heating circuit and heating plate, the heating plate with 2 fixed connection of LCD display module, heating plate electric connection heating circuit, the temperature control inductor is connected heating circuit controls its break-make, heating circuit is used for control the heating plate heating, the temperature control inductor is located LCD display module 2, the temperature control inductor is used for responding to the peripheral temperature of LCD display module 2 reaches preset temperature value when the temperature, the control by temperature control inductor control heating circuit disconnection stops heating.
Furthermore, an interface 3 is arranged on the circuit board, the interface 3 comprises a communication interface and a power-on interface, and the communication interface is in communication connection with the LCD display module 2 and is used for data exchange between the LCD display module and external equipment; the power-on interface is electrically connected with the heating circuit and supplies power to the heating circuit.
In this embodiment, the temperature control sensor is connected to a driving circuit, the power-on interface is electrically connected to the driving circuit to supply power to the driving circuit, the temperature control sensor feeds back information to the driving circuit and drives the driving circuit to operate, and the driving circuit is in communication connection with the heating circuit and is used for controlling the on/off of the heating circuit.
It should be noted that the power supply is connected to the heating circuit and the driving circuit through the power-on interface to supply power to the heating circuit and the driving circuit, the temperature control sensor senses the temperature around the LCD display module and has a preset value, after the temperature is sensed to be lower than the preset value, information is fed back to the driving circuit, the driving circuit transmits information and controls the heating circuit to heat the heating plate, and when the temperature is higher than the preset value, the temperature control sensor stops the driving circuit to work so as to stop the heating circuit from heating the heating plate.
The working principle of the liquid crystal display module with the low-temperature automatic heating function lies in that:
the heating circuit of the heating plate is arranged on a circuit board of the LCD display module, the LCD display module is provided with a temperature control sensor, and after the parameters of the driving circuit and the heating circuit are set, when the temperature around the LCD display module is reduced to a set value, the temperature control sensor can control the driving circuit to start the heating circuit, so that the heating plate is heated, and the temperature of the LCD display module is compensated; when the temperature rises to the setting value, thereby the temperature control inductor stops drive circuit work and stops heating circuit heating the heating plate to realize LCD display module's low temperature self-heating function, improve microthermal display performance, reach LCD display module and also can obtain better display effect at low temperature.
