Abstract

A cooling system and a control method of the cooling system are provided. The cooling system includes a display device, a temperature sensor, a cooling fan and a temperature controller. The display device includes a backlight module. The temperature sensor is configured in the backlight module. The temperature sensor senses a first temperature of the backlight module and a second temperature of the backlight module. The first temperature is higher than the second temperature. The cooling fan is configured in the backlight module. The cooling fan provides a cooling path. The temperature controller receives the first temperature and the second temperature from the temperature sensor, and controls the cooling fan to enable or disable.

First claim

What is claimed is:

1. A cooling system, comprising:
a display device, configured to display an image, wherein the display device comprises a backlight module;
a temperature sensor, configured in the backlight module, and configured to sense a first temperature of the backlight module and a second temperature of the backlight module, wherein the first temperature is higher than the second temperature;
a cooling fan, configured in the backlight module, and configured to provide a cooling path; and
a temperature controller, configured to receive the first temperature and the second temperature from the temperature sensor, and control the cooling fan to enable or disable;
wherein the backlight module is disabled after disabling the cooling fan.

2. The cooling system of claim 1 , further comprising:
an air-conditioning system, electrically connected to the temperature controller, and configured to be turned on when the cooling fan is enabled.

3. The cooling system of claim 1 , further comprising:
an air-conditioning system, electrically connected to the temperature controller,
wherein the backlight module is enabled after the air-conditioning system is enabled.

4. The cooling system of claim 1 , wherein a driving power of the cooling fan is provided by a driving power of the backlight module.

5. The cooling system of claim 1 , wherein a driving power of the cooling fan is different from a driving power of the backlight module.

6. The cooling system of claim 1 , wherein when a temperature of the backlight module sensed by the temperature sensor is higher than the first temperature, the temperature controller enables the cooling fan.

7. The cooling system of claim 1 , wherein when a temperature of the backlight module sensed by the temperature sensor is lower than the second temperature, the temperature controller disables the cooling fan.

8. The cooling system of claim 1 , wherein the temperature sensor starts to sense a temperature of the backlight module after the backlight module is started up.

9. The cooling system of claim 8 , wherein the display device displays the temperature of the backlight module.

10. A control method of a cooling system, wherein the cooling system comprises a display device, a temperature sensor and a cooling fan, wherein the control method comprises:
detecting a status of a backlight module of the display device;
controlling the temperature sensor to sense a temperature of the backlight module after the backlight module is started up;
enabling the cooling fan when the temperature of the backlight module sensed by the temperature sensor is higher than a first temperature;
disabling the cooling fan when the temperature is lower than a second temperature,
wherein the first temperature is higher than the second temperature; and
disabling the backlight module after disabling the cooling fan.

11. The cooling system of claim 10 , further comprising:
disabling the backlight module before disabling the cooling fan.

12. A cooling system, comprising:
a power circuit, configured to provide a driving power;
a temperature sensor, configured in a cockpit, and configured to sense a first temperature of the cockpit and a second temperature of the cockpit, wherein the first temperature is higher than the second temperature;
a cooling fan, configured in the cockpit, and configured to provide a cooling path;
a temperature controller, configured to receive the first temperature and the second temperature from the temperature sensor, and control the cooling fan to enable or disable; and
a display device, configured to display an image,
wherein the display device comprises a backlight module, and
wherein the backlight module is started up when the cooling fan is disabled.

13. The cooling system of claim 12 , further comprising:
an air-conditioning system, electrically connected to the temperature controller, and configured to enable the cooling fan according to the first temperature.

14. The cooling system of claim 12 , further comprising:
a car-machine system, electrically connected to the temperature controller,
wherein the temperature controller is started up when the car-machine system is started up.

15. The cooling system of claim 14 , wherein the driving power of the cooling system is provided by the car-machine system.

16. The cooling system of claim 12 , wherein when a temperature sensed by the temperature sensor is higher than the first temperature, the temperature controller enables the cooling fan.

17. The cooling system of claim 12 , wherein when a temperature sensed by the temperature sensor is lower than the second temperature, the temperature controller disables the cooling fan.
