Graphene heating plate is arranged on below the LED display, keeps thermally contacting with LED display, the graphene heating plate connects
Connect intelligent temperature control circuit and Programmable Temperature control is realized by intelligent temperature control circuit.
Specifically, microcontroller, temperature-sensitive module and drive module, institute are included referring to Fig. 2, the intelligent temperature control circuit
State temperature-sensitive module and gathered by thermistor NTC the temperature of environment temperature and graphene heating plate, the microcontroller root
The temperature value collected according to temperature-sensitive module come drive the heating of graphene heating plate act, and then realize regulation LED display work
Make the purpose of temperature.
In the course of the work, when intelligent temperature control circuit sense environment temperature it is extremely low in the case of then drive graphene to heat
Plate heat temperature raising, so as to create relatively stable working temperature environment for LED display, make LED display in extremely low temperature
It can continue to keep optimal working condition in section, such as -60 DEG C~-40 DEG C of environment temperature.
Preferably, the LED display is miniature LED display, applied in wearing or hand-hold electronic equipments.The system
The volume of middle graphene heating plate is extra small, and power consumption and cost are all relatively low, is particularly suitable for application in wearing or hand-hold electronic equipments.
In a word, the utility model preferred embodiment is these are only, is not intended to limit the scope of protection of the utility model,
Within scope of the present utility model, the equivalents or modification made to the utility model should be included in this practicality newly
Within the protection domain of type.
