Abstract

A display device for an air conditioning system of a vehicle, may include a display unit, and a control unit of controlling the display unit, wherein the control unit controls brightness in intensity or cycle, or color in a predetermined range of the display unit in accordance with a welcome function or a goodbye function.

Claims

1. A display device for an air conditioning system of a vehicle, comprising:

a display unit of displaying brightness variations and color variations; and

a control unit of controlling the display unit to perform a welcome function by which brightness intensity on the display unit gradually increases while still varying colors on the display unit when electric power is applied to the display device.

2. The display device of claim 1, wherein the control unit controls the display unit to perform the welcome function within 3 seconds.

3. The display device of claim 1, wherein the control unit controls the display unit to change colors on a screen of the display unit to colors having been predetermined in response to an indoor temperature of the vehicle after the welcome function is finished.

4. The display device of claim 3, wherein the control unit controls the display unit to perform the welcome function within 3 seconds.

5. The display device of claim 3, wherein the indoor temperature is a discharge temperature or a set up temperature having been set up before the air conditioning system is turned off.

6. The display device of claim 5, wherein the control unit controls the display unit to perform the welcome function within 3 seconds.

7. A display device for an air conditioning system of a vehicle, comprising:

a display of displaying brightness variations and color variations; and

a control unit of controlling the display to perform a goodbye function by which brightness intensity on the display gradually decrease while still varying colors on the display when an off button is pushed.

8. The device of claim 7, wherein the control unit controls the display unit to perform the welcome function within 3 seconds.

9. The device of claim 7, wherein the control unit controls the display to change colors on a screen of the display to colors having been predetermined in response to an outdoor temperature of the vehicle after the goodbye function is finished.

10. The device of claim 9, wherein the control unit controls the display unit to perform the welcome function within 3 seconds.

11. A method of controlling a display device for an air conditioning system of a vehicle, comprising the steps of:

controlling through a control unit performing of a welcome function by which brightness intensities gradually increase while still varying colors on a display when electric power is applied to the display device; and

displaying through the display brightness variations and color variations.

12. The method of claim 11, wherein the control unit controls the display to perform the welcome function within 3 seconds.

13. The method of claim 11, further comprising the step of controlling through the control unit the display to change colors on a screen of the display to colors having been predetermined in response to a discharge temperature or a set up temperature having been set up before the air conditioning system is turned off after the welcome function is finished.

14. The method of claim 13, wherein the control unit controls the display to perform the welcome function within 3 seconds.

15. A method of controlling a display device for an air conditioning system of a vehicle, comprising the steps of:

controlling through a control unit performing of a goodbye function by which brightness intensities gradually decrease while still varying colors on a display when an off button of the air conditioning system is pushed; and

displaying through a display brightness variations and color variations.

16. The method of claim 15, wherein the control unit controls the display to perform the goodbye function within 3 seconds.

17. The method of claim 15, wherein the control unit controls the display to change colors on a screen of the display to colors having been predetermined in response to an outdoor temperature of the vehicle after the goodbye function is finished.

18. The method of claim 17, wherein the control unit controls the display to perform the goodbye function within 3 seconds.

19. A display device for an air conditioning system of a vehicle, comprising:

a display unit; and

a control unit of controlling the display unit;

wherein the control unit controls brightness in intensity or cycle, or color in a predetermined range of the display unit in accordance with a welcome function or a goodbye function.
