Plastic Remote Control 56 keys for LG OLED55G2PSA/ LG 43UK6360PTE/ LG OLED77C2PSC TV
The transmitting circuit of infrared remote control uses infrared light emitting diode to emit modulated infrared light wave; The infrared receiving circuit is composed of an infrared receiving diode, a triode or a silicon photocell, which converts the infrared light emitted by the infrared emitter into a corresponding electrical signal and then sends it to the post amplifier. The transmitter is generally composed of command key (or operating lever), command coding system, modulation circuit, drive circuit, transmission circuit, etc. When the command key is pressed or the operating lever is pushed, the command coding circuit generates the required command coding signal. The command coding signal modulates the carrier wave, and then the power is amplified by the driving circuit, and the modulated command coding signal is transmitted from the transmitting circuit
