Meanwhile, since the communication module is built in the air conditioner illustrated in FIGS. 1 and 2, communication with the remote controller 100 is possible. In addition, since the communication module is also provided in the remote controller shown in FIGS. 3 and 4, the main controller (not shown) of the air conditioner controls the indoor unit or the outdoor unit according to the control signal received from the remote controller to control signals. Accordingly, the operation is performed.

In this case, the communication module exemplifies based on infrared communication, but in addition, a communication module using a frequency band such as Bluetooth or WLAN may be used. In addition, the communication module provided in the air conditioner or / and the remote controller 100 is a unidirectional communication module in which a signal is transmitted only from the remote controller to the air conditioner, or two-way communication in which the remote controller and the air conditioner transmit and receive signals to each other. Module.

If the unidirectional communication module is applied, the remote controller 100 unilaterally transmits a control signal, and the air conditioner side receives the control signal. However, if a two-way communication module is applied, the remote controller not only transmits a control signal, but also the air conditioner side can transmit a status information signal related to the operation and other data input / updated from the main body to the remote controller. do.

In addition, the remote controller 100 which transmits a control signal to the air conditioner includes an input unit 110 provided with at least one button, and a liquid crystal display unit 120 displaying control state information according to manipulation of the input unit.

In addition, the control unit 140 generates a control signal according to the operation of the input unit 110, is responsible for the transmission of the control signal, and controls an input / output state through the input unit and the liquid crystal display unit 120.

The liquid crystal display 120 displays numbers, letters, graphics, icons, and the like by operating the shortcut buttons and the first and second buttons.

The display unit of the present invention illustrates that the liquid crystal (LCD) display unit 120 is used. It consists of a panel (not shown) formed by filling a liquid crystal between two glass plates, and a backlight (not shown) positioned behind the panel to emit light.

That is, the molecular structure of the liquid crystal is changed by supplying a voltage by connecting an electrode to each cell constituting the panel, and is displayed by adjusting the amount of light coming from the backlight.

In this case, the brightness of the backlight may be adjusted so that the background color of the liquid crystal display 120 may be darkened or lightened, and the background color may also be changed. That is, the luminance or color of the background may be changed to display the operation mode, the operation state, the setting completion status, etc. by the operation of the input unit 110.

In addition, the brightness of the backlight may be increased during a specific time period (eg, night mode), and the brightness of the backlight may be decreased during the remaining time period (eg, day mode). The operation of the liquid crystal display 120 is controlled by the controller 140.

In this case, the liquid crystal display 120 may be classified into a positive type and a negative type by passing or blocking light of the backlight by using polarized light. The light of the backlight is supplied by supplying a voltage to an electrode. In the positive method of blocking the background 121a is bright and the letters or numbers 121b are displayed black, and in the negative method of passing the light of the backlight, the background is dark and the letters or numbers are bright. In FIG. 4, the positive method is illustrated, but a negative method is also possible.

The liquid crystal display 120 uses a voltage higher than the basic voltage used by the remote controller for driving the backlight. For this purpose, the liquid crystal display 120 includes a basic voltage (first voltage). And a voltage converter 170 for raising the voltage to a higher voltage (called a second voltage).

That is, the second power supply unit 160 for supplying the basic power from the rechargeable battery or the disposable battery inserted into the remote controller 100 supplies a first voltage to each component, and is raised by the voltage converter 170. A voltage source drives the backlight of the liquid crystal display 120. At this time, when the first voltage is 3V, the second voltage is 5V, but of course, may be a different voltage level according to the battery standard or the backlight standard.

In addition, at least one LED 130 is provided at a lower portion or a side portion of the liquid crystal display 120 or at a lower portion or a side portion of the input unit 110. The at least one LED may emit the same color, or any one color may be a device emitting a different color from the others.

The LED 130 may be turned on to indicate an operation mode, an operation state, setting completion, etc. by operating the input unit 110, and may also be turned on for a specific time period (eg, night mode), and the rest of the time zone ( (Eg daylight mode) can be turned off. The operation of the LED 130 is also controlled by the controller 140.

That is, in addition to visually confirming that icons, menus, etc. displayed on the liquid crystal display 120 are changed according to a button operation, the background color of the liquid crystal display may be changed or the LED 130 is turned on in hardware. It is possible to easily check the operation state by the user operation.
