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. ## Claims ### Claim 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. ### Claim 2 (depends on 1) 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. ### Claim 3 (depends on 1) 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. ### Claim 4 (depends on 1) The cooling system of claim 1, wherein a driving power of the cooling fan is provided by a driving power of the backlight module. ### Claim 5 (depends on 1) The cooling system of claim 1, wherein a driving power of the cooling fan is different from a driving power of the backlight module. ### Claim 6 (depends on 1) 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. ### Claim 7 (depends on 1) 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. ### Claim 8 (depends on 1) 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. ### Claim 9 (depends on 8) The cooling system of claim 8, wherein the display device displays the temperature of the backlight module. ### Claim 10 (depends on 1) The cooling system of claim 1, wherein the backlight module is disabled after disabling the cooling fan. ### Claim 11 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; and disabling the cooling fan when the temperature is lower than a second temperature, wherein the first temperature is higher than the second temperature. ### Claim 12 (depends on 11) The control method of claim 11, further comprising: disabling the backlight module after disabling the cooling fan. ### Claim 13 (depends on 11) The cooling system of claim 11, further comprising: disabling the backlight module before disabling the cooling fan. ### Claim 14 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; 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. ### Claim 15 (depends on 14) The cooling system of claim 14, further comprising: an air-conditioning system, electrically connected to the temperature controller, and configured to enable the cooling fan according to the first temperature. ### Claim 16 (depends on 14) The cooling system of claim 14, 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. ### Claim 17 (depends on 16) The cooling system of claim 16, wherein the driving power of the cooling system is provided by the car-machine system. ### Claim 18 (depends on 14) The cooling system of claim 14, wherein when a temperature sensed by the temperature sensor is higher than the first temperature, the temperature controller enables the cooling fan. ### Claim 19 (depends on 14) The cooling system of claim 14, wherein when a temperature sensed by the temperature sensor is lower than the second temperature, the temperature controller disables the cooling fan. ### Claim 20 (depends on 14) The cooling system of claim 14, further comprising: 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.
