Conventionally, a power supply unit 5 for supplying power, an operation input unit 6 for inputting an operation function desired by a user, a control unit 7 for controlling an operation according to the input signal, and a controlled signal of the control unit And a display unit 8 for emitting light.

Looking at the output control process of the display unit in the conventional separate type air conditioner through the configuration as follows.

2 is a flowchart illustrating a display unit output control of a separate air conditioner according to the related art.

The control unit 7 determines whether the operating state of the air conditioner is in operation (step 100).

If the control unit 7 determines that the operating state of the air conditioner is in operation, the control unit 7 outputs a signal for turning on the display unit 8, and the display unit 8 is turned on (step 102).

However, if the control unit 7 determines that the operating state of the air conditioner is not in operation, the control unit 7 does not output a signal for turning on the display unit. Therefore, the display section 8 does not light (step 104).

Looking at the case of the sleep function as well as the driving function as described above are as follows.

The control unit 7 determines whether the operating state of the air conditioner is sleeping (step 106).

If the control unit 7 determines that the operating state of the air conditioner is sleeping, the control unit 7 outputs a signal for turning on the display unit 8, and the display unit 8 lights up (step 108).

However, if the control unit 7 determines that the operating state of the air conditioner is not sleeping, the control unit 7 does not output a signal for turning on the display unit. Therefore, the display unit 8 does not light (step 110).

In addition, there is a reservation function that reserves the function of the air conditioner and a defrost function to compensate for the internal cold caused by the cold air of the air conditioner for a long time.

A control flowchart indicating the brightness of the reservation display unit is as follows.

The control unit 7 determines whether the operation state of the air conditioner is being reserved (step 112).

If the control unit 7 determines that the operating state of the air conditioner is being reserved, the control unit 7 outputs a signal for turning on the display unit 8, and the display unit 8 lights up (step 114).

However, if the control unit 7 determines that the operating state of the air conditioner is not reserved, the control unit 7 does not output a signal for turning on the display unit. Therefore, the display portion 8 does not light (step 116).

A control flow chart showing the brightness of the defrost display unit is as follows.

The control unit 7 determines whether the operating state of the air conditioner is being defrosted (step 118).

If the control unit 7 determines that the operating state of the air conditioner is in defrost, the control unit 7 outputs a signal for turning on the display unit 8, and the display unit 8 is turned on (step 120).

However, if the control unit 7 determines that the operating state of the air conditioner is not in defrost, the control unit 7 does not output a signal for turning on the display unit. Therefore, the display section 8 does not light (step 122).

That is, the display unit of the air conditioner according to the related art is turned on when the air conditioner is in operation, and the display unit displaying the operation is not lit when the air conditioner is not in operation. For example, when the operating state of the air conditioner is in operation, the operation display unit is turned on. If the operating state of the air conditioner is not in operation, the operation display unit is not lit. In addition, when the operating state of the air conditioner is going to bed, the sleep indication unit is turned on. If the operating state of the air conditioner is not going to sleep, the sleep indication unit is not lit.

As described above, the display unit of the air conditioner according to the related art is controlled by only turning on or turning off the light, and the brightness of the display unit cannot be adjusted in multiple stages according to the needs of the user.

Accordingly, an object of the present invention is to provide a display unit brightness control method of a separate type air conditioner to control the brightness of the display unit in a multi-step in performing the control of the brightness of the air conditioner display unit.

According to another aspect of the present invention, there is provided a method of controlling a display unit of a separate air conditioner, including: determining an operating function of the air conditioner; Controlling the brightness of the display unit of the air conditioner according to a key input to be adjusted; and displaying the controlled signal on the display unit.

Hereinafter, a method of controlling brightness of a display unit of a separate type air conditioner according to the present invention will be described in detail with reference to the accompanying drawings.

3A is a front view of a separate air conditioner main body according to the present invention.

The main body of the separate type air conditioner includes a discharge port 80 for discharging cold air to the outside, and a display unit plate 85 for displaying a user's confirmation of each operation function of the air conditioner. In addition, the display panel 85 is a key input unit 60 for the user to input each operation function of the air conditioner, the brightness of the display unit according to each operation function and the adjustment according to each operation function according to the key input And a display unit 30 indicating the brightness.

According to the operation function through the key input unit 60, the air driven in the air conditioner is discharged through the discharge port 80 provided in the main body of the separate type air conditioner, and each operation function input by the user through the display unit 30. The brightness of the display unit 30 according to the display is displayed.

3B is an enlarged view of the display panel provided in the main body of the separate type air conditioner.

The user inputs each operation function of the air conditioner and the brightness of the display unit 30 through the key input unit 60 provided in the display panel 85. The input signal is transmitted to the controller 10, and the controller 10 controls the transmitted signal and outputs the signal to the display unit 30. The signal is input to the display unit 30 provided on the display plate 85 by the signal. In response to the signal, the display unit 30 is output at the brightness input by the user. Therefore, the brightness of the display unit 30 adjusted by the user is shown.

Figure 4a is a block diagram for outputting the brightness of the display unit of the separate air conditioner according to the present invention in multiple stages.

A power supply unit 50 for supplying power to the air conditioner, a key input unit 60 for inputting an operation function of the air conditioner, and adjusting the brightness of the display unit, and a brightness of the display unit according to the input signal of the key input unit 60 The control unit 10 for controlling the light and the display unit 30 for emitting light in accordance with the controlled signal.

That is, power is supplied through the power supply unit 50, and the user inputs the operation function of the air conditioner and the brightness of the display unit through the key input unit 60. The control unit 10 controls the brightness of the display unit according to the signal input through the key input unit 60. The controlled signal is transmitted to the display unit 30. The brightness of the display unit 30 is output by the signal transmitted to the display unit 30.

4 shows an output port detail circuit of the display unit 30 in the present invention configured as described above.

Figure 4b shows a display unit output port detailed circuit of a separate air conditioner according to the present invention.

The circuit includes a power supply unit 50 for supplying power, a resistor 40 for preventing overload due to input power, a controller 10 for controlling a waveform according to an input signal, and an output waveform of a controlled signal. The inverter 20 includes an inverting inverter, a display unit 30 indicating the brightness of the LED by the controlled signal, and a key input unit 60 controlling the operation function of the air conditioner and the brightness of the display unit.

When the voltage 5V input through the power supply unit 50 is directly applied to the display unit 30, the resistor 40 is compensated by connecting the power source and the LED 30 to prevent overload. In addition, due to the inverter 20 located between the LED 30 and the controller 10, the output waveform outputs the opposite value to the circuit value and is represented by the lower limit waveform.

That is, when the user inputs the brightness of the display unit of the air conditioner through the key input unit 60, the input signal is input to the controller 10. The controller 10 outputs a control signal based on an input signal as a waveform at an output port. The waveform is output by inverting the output waveform through the inverter 20. The inverted output waveform is input to the display unit 30, and the display unit 30 is turned on.

5 is an output waveform shown in the display unit output port detailed circuit of the separate air conditioner according to the present invention.

As shown in FIG. 5, T1 is the OFF time of the display unit and represents the brightness of the dark display unit. Therefore, when the T1 period is increased according to the control signal of the controller 10, the brightness of the display unit becomes darker.

And T2 is the scan period, which is the maximum time that seems to be ON continuously from the human perspective, usually 4ms. The OFF time T1 of the display unit always shows the output waveform within the scan period T2.

As can be seen from the output waveform, the controller 10 controls the period T1 to control the intensity of the display brightness in multiple stages. That is, the brightness of the display unit is configured in the order of maximum, ① method, ② method, and (N) method. In addition, the control unit 10 controls the T1 period to be increased in the order of the brightness level, and as the T1 period is increased, the brightness is darker.

Therefore, there is no period of T1 indicating the dark display part in the scan period T2 at the maximum of the brightest of the display parts. The period of T1 in the scan period T2 is the longest at the brightness N where the brightness of the display is the darkest.

The configuration diagram for controlling the brightness of the display unit and the output waveform according to the configuration have been described above.

Hereinafter, an operation process of controlling the brightness of the display unit of the air conditioner will be described.

6A, 6B, 6C, and 6D show a flow chart of the display control of the split type air conditioner according to the present invention.

The display control output flow chart of the separate type air conditioner according to the present invention is a process of controlling the display brightness of each function in the operation, sleep, reservation, and defrost functions.

6A is a control flowchart illustrating brightness of a driving display unit.

The controller 10 determines whether the air conditioner is in operation (200).

If the controller 10 determines that the device is not operating in operation 200, the controller 10 controls the output waveform to be low in the output port circuit of the display unit 30. The controlled output waveform is input to the display unit 30, and the display unit 30 is turned off (step 202).

However, if the signal input by the user through the key input unit 60 is a driving function of the air conditioner, the user adjusts the brightness of the driving display unit through the key input unit 60 (step 204).

Therefore, when there is no input of the key input unit 60 in step 204, the output waveform is output in the maximum bright? Method from the output port circuit of the display unit 10. In the ⓞ method, there is no T1 period for controlling the dark brightness. Therefore, when the output waveform is input to the display unit 30, the display unit 30 is most brightly lit (step 206).

However, if the user does not want the brightest display, he can choose one level lower brightness level. When the user inputs the key input unit 60 once in step 204, the controller 10 determines the input signal (step 208).

The control unit 10 controls the input signal, and outputs an output waveform in a ① manner from an output port circuit of the display unit 30. The ① method represents one level of light intensity in the brightest ⓞ method. Therefore, when the output waveform is input to the display unit, the display unit 30 is turned on by the brightness of the ① method (step 210).

However, if the brightness of the ① method is not the brightness of the display unit desired by the user, the input of the key input unit 60 continues. In step 208, when the user inputs the key input unit 60 twice, the controller 10 determines whether the number of input keys is twice (step 212).

If the determination is correct, the output waveform of the control unit 10 outputs the output waveform in a darker ② manner than the ① manner. Therefore, the output waveform is input to the display unit 30 and the brightness of the display unit 30 is turned on in the manner of ② (step 214).

However, when the user inputs the brightness of the darkest display unit, the controller 10 determines whether the input of the key input unit 60 is N times (step 216). If the control unit 10 determines that the number of key inputs is N times, the control unit 10 controls the output port circuit of the display unit to output the output waveform in the darkest (N) manner. Therefore, the controlled output waveform is input to the display unit 30, and the display unit 30 is turned on at the darkest brightness (step 218).

Accordingly, in selecting the brightness of the display unit as described above, the user may input the key input unit 60 in multiple stages to select the desired brightness of the display unit.

However, if the user inputs N + 1 times through the key input unit 60 (step 220), the controller 10 determines the signal of the key input unit 60, and outputs an output waveform through the output port circuit of the display unit. The control unit 10 controls to output (N + 1). The controlled output waveform is input to the display unit 30. The (N + 1) method is an LED OFF signal, and the display unit 30 is turned off due to the output waveform controlled by the (N + 1) method (step 222).

When the user inputs (N + 2) times through the key input unit 60 (step 224), the input signal is input to the controller 10. The control unit 10 controls the number of inputs of the key input unit 60 to adjust brightness. Accordingly, the user may execute the above process for selecting the desired brightness of the display unit 30 again (Step 226).

6B is a control flowchart illustrating brightness of the sleep display unit.

The controller 10 determines whether the air conditioner is in the sleep mode (operation 300).

If the controller 10 determines that the sleep operation is not performed in step 300, the controller 10 controls the output waveform to be low from the output port circuit of the display unit. The controlled output waveform is input to the display unit 30, and the display unit 30 is turned off (step 302).

However, when the signal input by the user through the key input unit 60 is a sleep function of the air conditioner, the user adjusts the brightness of the sleep display unit to the key input unit 60 (step 304).

Therefore, when there is no input of the key input unit 70 in the step 304, the output waveform is output in the? Method of the maximum brightness in the output port circuit of the display unit 30. In the ⓞ method, there is no T1 period for controlling the dark brightness. Therefore, when the output waveform is input to the display unit, the display unit 30 is brightest (step 306).

However, if the user does not want the brightest display, the user can adjust the brightness of the display through the key input unit 60. Accordingly, when the user inputs the input signal once through the key input unit 60 in step 304, the controller 10 determines the input signal (step 308).

The control unit 10 controls the input signal, and outputs an output waveform in a ① manner in the output port circuit of the display unit. The ① method indicates the light intensity of one level lower in the maximum brightness ⓞ method of the display unit. Therefore, when the output waveform is input to the display unit, the display unit 30 is turned on by the brightness of the ① method (step 310).

However, when the brightness of the ① method is not the brightness of the display unit desired by the user, the input of the key input unit 60 continues. If the user inputs twice through the key input unit 60 in step 308, the controller 10 determines whether the number of input keys is twice (step 312).

If the determination is correct, the output waveform of the control unit 10 outputs the output waveform in a darker ② manner than the ① manner. Accordingly, the output waveform is input to the display unit 30, and the brightness of the display unit 30 is turned on in the ② method (step 314).

However, if the user wants the display unit having the darkest brightness, the user inputs N times through the key input unit 60 (step 316). The control unit 10 controls the input signal to output an output waveform in a darker (N) method than the ② method in the output port circuit of the display unit. The output waveform controlled by the controller 10 is input to the display unit 30, and the display unit 30 is turned on at the darkest brightness (step 318).

If the user inputs N + 1 times through the key input unit 60 (step 320), the controller 10 determines the signal of the key input unit 60, and the output waveform of the display unit outputs (N). The control unit 10 controls to output in the +1) manner. The controlled output waveform is input to the display unit 30. The (N + 1) method is an LED OFF signal, and the display unit 30 is turned off due to the output waveform controlled by the (N + 1) method (step 322).

When the user inputs (N + 2) times through the key input unit 60 (step 324), the input signal is input to the controller 10. The control unit 10 controls the number of inputs of the key input unit 60 to adjust the brightness to be initialized. Therefore, the user may again perform the process of adjusting the brightness of the desired display unit (operation 326).

6C is a control flowchart showing the brightness of the reservation display unit.

The controller 10 determines whether the air conditioner is in the reservation function (operation 400).

If the controller 10 determines that a reservation is not made in operation 400, the controller 10 controls the output waveform of the display port to be low. The controlled output waveform is input to the display unit 30, and the display unit 30 is turned off (step 402).

However, if the signal input by the user through the key input unit 60 is a reservation function of the air conditioner, the user adjusts the brightness of the reservation display unit to the key input unit 60 (step 404).

Accordingly, when there is no input of the key input unit 60 in step 404, the output waveform is output in the brightest ⓞ method from the output port circuit of the display unit 30. In the ⓞ method, there is no T1 period for controlling the dark brightness. Therefore, when the output waveform is input to the display unit 30, the display unit 30 is most brightly lit (step 406).

However, if the user does not want the brightest display, the user can adjust the brightness of the display through the key input unit 60. Accordingly, when the user inputs the input signal once through the key input unit 60 in step 404, the control unit 10 determines the input signal (step 408).

The controller 10 controls the input signal and outputs an output waveform in a ① manner from an output port of the controller 10. The ① method represents one level of light intensity in the brightest ⓞ method. Therefore, when the output waveform is input to the display unit 30, the display unit 30 is turned on with the brightness of the ① method (step 410).

However, if the brightness of the ① method is not the brightness of the display unit 30 desired by the user, the input through the key input unit 60 continues. If the user inputs twice through the key input unit 60 in step 408, the controller 10 determines whether the number of input keys is twice (step 412).

If the determination is correct, the output waveform of the control unit 10 outputs the output waveform in a darker ② manner than the ① manner. Therefore, the output waveform is input to the display unit 30, and the brightness of the display unit 30 is turned on in the ② method (step 414).

However, if the user wants the display with the darkest brightness, the user inputs N times through the key input unit 60 (step 416). The control unit 10 controls the input signal to output an output waveform in a darker (N) method than the ② method in the output port circuit of the display unit. The output waveform controlled by the controller 10 is input to the display unit, and the display unit 30 is turned on at the darkest brightness (step 418).

If the user inputs N + 1 times through the key input unit 60 (operation 420), the controller 10 determines the signal of the key input unit 60, and the output waveform of the display unit outputs (N). The control unit 10 controls to output in the +1) manner. The controlled output waveform is input to the display unit 30. The (N + 1) method is an LED OFF signal, and the display unit 30 is turned off due to the output waveform controlled by the (N + 1) method (step 422).

When the user inputs (N + 2) times through the key input unit 60 (step 424), the input signal is input to the controller 10. The control unit 10 controls the number of inputs through the key input unit 60 to initialize the brightness. Accordingly, the user may again perform the process of adjusting the brightness of the desired display unit (operation 426).

6D is a control flowchart illustrating the brightness of the defrost display unit.

The controller 10 determines whether the air conditioner is in a defrost function (operation 500).

If the controller 10 determines that the defrost is not performed in operation 500, the controller 10 controls the output waveform to be low in the output port circuit of the display unit. The controlled output waveform is input to the display unit, and the defrost display unit is turned off (step 502).

However, if the signal input by the user through the key input unit 60 is a defrost function of the air conditioner, the user adjusts the brightness of the driving display unit through the key input unit 60 (step 504).

Accordingly, when there is no input of the key input unit 60 in step 504, the output waveform is output in the brightest ⓞ method from the output port circuit of the display unit 30. In the ⓞ method, there is no T1 period for controlling the dark brightness. Therefore, when the output waveform is input to the display unit 30, the display unit 30 is most brightly lit (step 506).

However, if the user does not want the brightest display, the user can adjust the brightness of the display through the key input unit 60. Accordingly, when the user inputs the key through the key input unit 60 at step 504, the controller 10 determines the input signal (step 508).

The controller 10 controls the input signal and outputs an output waveform in a ① manner from an output port of the controller 10. The ① method represents one level of light intensity in the brightest ⓞ method. Therefore, when the output waveform is input to the display unit 30, the display unit 30 is turned on with the brightness of the ① method (step 510).

However, if the brightness of the ① method is not the brightness of the display unit 30 desired by the user, the input through the key input unit 60 continues. When the user presses the key twice through the key input unit 60 in step 508, the controller 10 determines whether the number of input keys is twice (step 512).

If the determination is correct, the output waveform of the control unit 10 outputs the output waveform in a darker ② manner than the ① manner. Therefore, the output waveform is input to the display unit 30, and the brightness of the display unit 30 is turned on in the ② method (step 514).

However, if the user wants the display unit having the darkest brightness, the user inputs N times through the key input unit 60 (step 516). The control unit 10 controls the input signal to output the output waveform in the darkest (N) manner in the output port circuit of the display unit. The output waveform controlled by the controller 10 is input to the display unit 30, and the display unit 30 is turned on at the darkest brightness (step 518).

If the user inputs N + 1 times through the key input unit 60 (step 520), the controller 10 determines the signal of the key input unit 60, and the output waveform of the display unit outputs (N). The control unit 10 controls to output in the +1) manner. The controlled output waveform is input to the display unit 30. The (N + 1) method is an LED OFF signal, and the display unit 30 is turned off due to the output waveform controlled by the (N + 1) method (step 522).

When the user inputs (N + 2) times through the key input unit 60 (step 524), the input signal is input to the controller 10. The control unit 10 controls the number of inputs of the key input unit 60 to adjust brightness. Therefore, the user may again perform the process of adjusting the brightness of the desired display unit (operation 526).

As described above, according to the present invention, the control unit controls a signal in which the brightness of the display unit is input in multiple stages through the key input unit, and outputs the control signal to the display unit to adjust the display unit brightness of the air conditioner in multiple stages.

Therefore, the present invention has a feature that can control the brightness of the display unit in multiple stages compared to the same product. Therefore, the brightness can be adjusted at bedtime or according to the needs of the user, thereby providing the user with convenience and product satisfaction.
