Disposable electronic cigarettes with display screens are now very popular overseas and are constantly evolving, from simple black and white LED digital tubes to colorful TFT screens. The display content ranges from simple oil and electricity displays to animations and even the ability to play games.ELF BOX Digital 12000, Bang BOX 18000, EPE AP15000, Elfworld I15pro 12000, ZOOY DIAMOND 15000 are all very popular and excellent screen electronic cigarettes.
This trend has driven the demand for TFT displays on one hand, and on the other hand, the application of TFT screens has also driven the growth of demand for MCUs.
MCU, also known as Micro Control Unit, refers to the integration of a computer's CPU, RAM, ROM, timing counter, and various I/O interfaces on a single chip, forming a chip level computer with the emergence and development of large-scale integrated circuits.
A microcontroller can be seen as a type of IC, which is one of the components of the electronic cigarette solution circuit. Different types of ICs are combined with components such as resistors and capacitors to form circuit modules with certain functions. In order to implement specific programs, it is also necessary to burn and solidify the program into the program memory of the microcontroller.
MCU can achieve functions such as power adjustment, mode switching, and temperature control for electronic cigarettes, playing a role in short circuit protection, over suction protection, etc. It is reported that a TFT screen solution generally requires a 32-bit MCU as the core control unit, responsible for coordinating and controlling the entire system. TFT color screens achieve precise color control and fast response.
