The biggest advantage of wireless RF remote control is its scope: they can transfer distance of up to 30 meters away from the receiver, the wireless signal can pass through walls. It is precisely because of these advantages, you will look around for a home theater components IR / RF remote control. The remote control uses infrared / RF converters to extend the transmission range of the infrared remote control.

LCD TV remote control remote control signal is formed mainly by the microprocessor chips, crystal oscillator, amplifying transistor, an infrared light emitting diode and a keyboard matrix composition. It works as follows IC1 microprocessor chip internal oscillator by 2,3 feet composed with an external crystal oscillator X a high frequency oscillator which generates a high-frequency oscillation signal (480kHz). This signal is generated sinusoidal signal

TV remote control is a mechanical means for remote control. Modern remote control, mainly by the integrated circuit board and used to generate different messages composed buttons. There is a built-called 'central processor', the English called CPU, it is the TV computer, CPU in the manufacture of various menus TV will enter one password information, as long as the TV remote control transmitter to issue the corresponding password We can achieve the TV's remote control.

Mainly rely on the TV remote control integrated circuit (also known as chips) to send commands, the chip uses a 18-pin dual in-line package (DIP package abbreviated DIP). On the right side of the chip, you can see a diode, a transistor (black, three pins), a resonator (yellow), two resistors (green) and a capacitor (dark blue). Next there is a battery in the contact resistance (green) and a capacitor (small brown discs). In this circuit, the chip can detect when a key is pressed.

invention (All-around wireless) TV remote control is a fully-fledged lazy invention, today's remote control has many features, Samsung also launched even a built operating system for smart remote control. But the world's first remote control invented by whom, but also look like it? Surprisingly, the answer, in 1961, RCA Victor on the production of the first wireless remote control

Today, television technology has become more sophisticated, smart TV unknowingly already become an indispensable part of people's lives. Smart TV itself has a very flexible mode of operation, including the traditional remote control remote control, remote intelligent devices and so on. However, for the elderly, intelligent remote control device becomes cumbersome way a lot, so that more older people will still use the traditional remote control to operate.

Now many household appliances are equipped with an infrared remote control device. But pay attention to the proper use and maintenance, or make the remote control malfunction or damage. 1. When using the remote control, the distance between the remote control and the remote control receiver of not more than 10 meters should be used with the remote control at the appliance receive direction, the angle of deviation of no more than about 25 degrees.

Now many household appliances are equipped with an infrared remote control device. How to properly use and maintain, in order to avoid the TV remote control does not work? Using the remote control should avoid bright light, including sunlight, lights, or the remote control will affect the use of effects. Long-term when not in the remote controller, the box inside the battery to prevent battery electrolyte leakage corrosion box element.
