Theair conditioner 140 includes anindoor unit 130 disposed in an indoor space and anoutdoor unit 120 disposed in an outdoor space. Theindoor unit 130 and theoutdoor unit 120 are communicatively connected to each other via anetwork 161. While theair conditioner 140 includes oneoutdoor unit 120 and oneindoor unit 130, the present invention is not limited thereto. Theair conditioner 140 may include one outdoor unit and a plurality of indoor units, or include a plurality of outdoor units and a plurality of indoor units. - Referring to
FIG. 2 , thecontrol device 110 is connected to theair conditioner 140 by wires. Thecontrol device 110 sets operating conditions of theair conditioner 140, and includes acontrol unit 160, afirst display unit 180, asecond display unit 170, adatabase 190, andfunction keys 150. A user can change the operating conditions of theair conditioner 140 after manipulating thecontrol device 110 to a predetermined setting mode state. Here, the setting mode is a setting mode in which various operating conditions of theair conditioner 140 can be inputted by the user. - Referring to
FIG. 2 , thedatabase 190 stores various displayable image data in thefirst display unit 180 and thesecond display unit 170, and thecontrol unit 160 represents images on thefirst display unit 180 and thesecond display unit 170 based on the image data stored in thedatabase 190. - Referring to
FIG. 3 , thecontrol device 110 can display the operating conditions of theair conditioner 140 through thefirst display unit 180 and thesecond display unit 170. Thefirst display unit 180 can be disposed longitudinally in thecontrol device 110, spaced apart a predetermined gap from thesecond display unit 170. - The
first display unit 180 displays the operating conditions of theair conditioner 140 in various images. Specifically, thefirst display unit 180 has an LCD panel structure, and the LCD panel structure is an FSTN (Film Super Twist Nematics). The LCD panel structure is divided into a TN LCD (Twsited Nematic LCD), a CTN (Complementary Tn), an STN (Super Twisted Nematic), a DSTN (Double Layer Super Twisted Nematic), an FSTN (Film Super Twist Nematics) and so forth depending on the physical properties of liquid crystal, the material of the panel, etc. The FSTN type uses a very thin polymerized film in place of a color compensating liquid crystal cell, and thefirst display unit 180 of the present invention employs an LCD panel structure of FSTN type that can obtain a wide view angle and is suitable for thinning. - In the present invention, a first image is changeably displayed on at least a first region of the
first display unit 180. Specifically, the first image represented on thefirst display unit 180 is a set of dots which is represented as one dot on the coordinate plane of thefirst display unit 180. That is, thefirst display unit 180 is a dot type LCD which represents an image in the set of dots, and can represent image data as an image by lighting the dots with the use of the image data stored in thedatabase 190. - The user can vary the image data in various ways by manipulation. The user can select the setting items and use the plurality of function keys for manipulating set values of the selected setting items to represent the setting items and the set values in a first image.
- The image data stored in the
database 190 is image data that can change the first image into various images, such as characters, numerals, etc. by a combination of dots. Thus, various images can be displayed by lighting the dots on the coordinate plane of thefirst display unit 180 by various combinations. For instance, thecontrol unit 160 can apply a signal for transmitting different image data on thefirst display unit 180. The signal is a signal which transmits image data in response to a signal for setting operating conditions, and turns on or off the dots on a predetermined coordinate of thefirst display unit 180. Hence, even on the same coordinate plane on the dot type LCD, which is thefirst display unit 180, an image can be represented as the characters, such as " set lock" as shown inFIG. 3 or " operation mode" as shown inFIG. 4 . That is, the image of " set lock" can be converted into the image of " operation mode" and represented on thefirst display unit 180. Accordingly, the characters indicating " set lock" and the characters indicating " operation mode" , which are different images, can be displayed on the same coordinate plane of thefirst display unit 180. - The operating conditions include predetermined setting items, and a first image of the setting items can be represented on the
first display unit 180. Here, on thefirst display unit 180, a settingitem display part 181 for representing the names of the setting items in the first image and a setvalue display part 182 for representing set values of the respective setting items in the first image are provided. Here, the setting items include an operation mode item, a ventilation item, a set temperature item, a room temperature item, a fan speed item, an air flow direction item, a sub function item, and a reservation item. The respective setting items have set values that the user can select or change. The first image corresponds to the respective setting items and the respective set values of the setting items, and the first image corresponding to the respective setting items and the respective set values are displayed on the settingitem display part 181 and setvalue display part 182, respectively, of thefirst display unit 180. - On the
second display unit 170, only a preset second image can be represented on at least a second region. Here, thesecond display unit 170 has an LCD panel structure like the above-describedfirst display unit 180, and the structure of the LCD panel may be an FTSN. Thesecond display unit 170 displays the operating conditions of the air conditioner in a graphic image display method or in an 88-segment method. Here, the second image is a preset graphic image. - Here, the size of the
first display unit 180 may be smaller than the size of thesecond display unit 170. Since a graphic image can be easily visually checked by the user, the size of thesecond display unit 170 is formed larger in order to easily visually check the operating conditions and precisely ascertain the operating conditions through the display contents of thefirst display unit 180. - Meanwhile, the operating conditions include predetermined setting items, and a second image of the setting items can be represented on the
second display unit 170. The second image corresponds to the setting items and respective set values of the setting items. That is, whenever the operating conditions are changed, the second image corresponds to the changed operating conditions. Here, the setting items include anoperation mode item 171, aventilation item 172, aset temperature item 173, aroom temperature item 174, afan speed item 175, an airflow direction item 176, asub function item 177, and a reservation item 178. - The respective setting items have set values that the user can select or change, and the set values are displayed in a second image on the
second display unit 170. Here, the second image can be represented in a graphic image as described above. The graphic image may be an pictogram which is represented so as to understand by intuition or an icon displayed in a small figure or symbol on the display screen, but the graphic image is not limited to the pictogram or icon. - Here, the graphic image is an image based on the image data stored in the
database 190. The graphic image can be represented on thesecond display unit 170 by lighting the graphic image with the use of the image data stored in thedatabase 190. Hence, only a set image can be represented by lighting the graphic image on the coordinate plane of thesecond display unit 170. Specifically, thecontrol unit 160 can apply a signal for transmitting the image data stored in thedatabase 190 on thesecond display unit 170. The signal is a signal which transmits set image data to thesecond display unit 170 in response to a signal for setting operating conditions and represents an image on thesecond display unit 170, and also a signal which turns on or off a graphic image on a predetermined coordinate plane of thesecond display unit 170 based on the set image data. Accordingly, on the same coordinate plane of thesecond display unit 170, only a set image can be displayed. That is, graphic images specific to the respective setting items and set values are preset on a predetermined coordinate plane of thesecond display unit 170. For instance, the respective operation items and set values as shown inFIG. 4 are represented in graphic images on thesecond display unit 170. Referring toFIG. 4 , animage 171 of " operation" indicating an operation mode and a cooling operationgraphic image 171a displaying a cooling operation, which is one of the set values of the operation mode, are represented on thesecond display unit 170. Besides, a dehumidification operation graphic image 171b corresponding to a set value of dehumidification operation in theoperation mode item 171 among the setting items and a heating operationgraphic image 171c corresponding to a set value of heating operation are displayed on the second display unit. On the coordinate plane of the second display unit where the cooling operationgraphic image 171a is lighted, the display of the dehumidification operation graphic image 171b is impossible. This is because only the cooling operationgraphic image 171a is preset to be lighted on the coordinate plane where the cooling operationgraphic image 171a is lighted. - Specifically, when the above-described setting mode is entered, the user can select the setting items and use the plurality of function keys for manipulating set values of the selected setting items to represent the setting items and the set values in a second image. For example, set values of cooling operation, dehumidification operation, and heating operation in the
