Referring to FIG. 1 and FIG. 2 , the present application provides a control method of the fan 30 for the display device 100 . The display device 100 includes a temperature sensor 10, a display screen 20, and a fan 30. The temperature sensor 10 and the fan 30 are disposed within the display device 100. The control method includes the following steps:

S10: determining whether the temperature T collected by the temperature sensor 10 is greater than a first preset value T1;

S20: If the temperature T collected by the temperature sensor 10 is not greater than the first preset value T1, the control fan 30 is not activated;

S30: If the temperature T collected by the temperature sensor 10 is greater than the first preset value T1, determine whether the temperature T collected by the temperature sensor 10 is greater than a second preset value T2, and the second preset value T2 is greater than the first preset. Value T1;

S40: If the temperature T collected by the temperature sensor 10 is greater than the first preset value T1 and not greater than the second preset value T2, the fan 30 is controlled according to the temperature T collected by the temperature sensor 10 and the brightness L of the display screen 20. status;

S50: If the temperature T collected by the temperature sensor 10 is greater than the second preset value T2, the control fan 30 operates at a first rotation speed R1 greater than the preset rotation speed.

The control method of the fan 30 according to the embodiment of the present application controls the rotation speed of the fan 30 according to the temperature T collected by the temperature sensor 10 and the brightness L of the display screen 20, and ensures the display device 100 is safe and reliable under different application scenarios and screen brightness. Run, while giving users a better listening experience.

It can be understood that the display device 100 generates a large amount of heat during the working process, especially the display device 100 with a high-brightness screen. If the heat is not dissipated in time, the stability and safety of the operation of the display device 100 are easily affected. Therefore, the display device 100 is provided with a fan 30 for heat dissipation. The fan 30 generates a certain amount of noise during operation, which affects the user's hearing experience. The control method of the fan 30 of the embodiment of the present application controls the rotation speed of the fan 30 according to the internal temperature of the display device 100 and the brightness L of the display screen 20 to ensure the safe operation of the display device 100 while reducing the noise of the fan 30.

Specifically, if the temperature T collected by the temperature sensor 10 is not greater than the first preset value T1 (T≤T1), the internal temperature of the display device 100 is low, and there is no risk of heat dissipation, and the brightness L of the display screen 20 is How much, the fan 30 is controlled not to be activated, so that the display device 100 is operated without noise. If the temperature T collected by the temperature sensor 10 is greater than the first preset value T1 and not greater than the second preset value T2 (T1 < T ≤ T2), the internal temperature of the display device 100 is high, and the display screen needs to be combined. The brightness L of 20 controls the state of the fan 30, and while ensuring heat dissipation of the display device 100, it also takes into account the user's hearing experience. If the temperature T collected by the temperature sensor 10 is greater than the second preset value T2 (T>T2), the internal temperature of the display device 100 is high, and there is a large risk of heat dissipation. At this time, the fan 30 is directly controlled to be greater than the preset. The first rotational speed R1 of the rotational speed is operated to ensure the heat dissipation effect of the display device 100. The range of the first predetermined value T1 can be set to any value between 50 ° C and 55 ° C, such as 50 ° C, 55 ° C or 50-55 ° C, preferably 53 ° C. The second predetermined value T2 can be set to any value between 60 ° C and 65 ° C, for example between 60 ° C, 65 ° C or 60-65 ° C, preferably 63 ° C. The first rotational speed R1 may range from 1400 to 1800 r/min, for example any value between 1400 r/min, 1800 r/min or 1400-1800 r/min, preferably 1600 r/min. In some embodiments, the first rotational speed R1 can be the maximum rotational speed of the fan.

In the embodiment of the present application, the internal temperature of the display device 100 is acquired by the temperature sensor 10 disposed in the display device 100, and the temperature sensor 10 may be disposed at any position inside the display device 100. Preferably, the temperature sensor 10 is set to work. Performance is near the components that are more affected by temperature. The brightness L of the display screen 20 is obtained by acquisition of a brightness sensor disposed below the display screen 20 or by an associated drive signal of the display screen 20.

In some embodiments, the control method includes the steps of detecting the brightness L of the display screen 20 and the temperature T collected by the temperature sensor 10 over a period of time.

Thus, in the case of the collected temperature value and brightness value, the power consumption of the display device 100 is reduced, and at the same time, the rotational speed of the fan 30 is frequently adjusted to cause the user to feel uncomfortable.

In certain embodiments, the period is 4-6 min/time.

Thus, a suitable detection period can avoid frequent adjustment of the rotational speed of the fan 30 and timely acquisition of the internal temperature of the display device 100 and the brightness L of the display screen 20 to control the rotational speed of the fan 30. Specifically, the period may be any value between 4 min/time, 6 min/time or 4-6 min/time, and preferably, the period is 5 min/time.

Referring to FIG. 3, in some embodiments, step S40 includes the following steps:

S400: It is determined whether the temperature T collected by the temperature sensor 10 is greater than a third preset value T3 and not greater than a second preset value T2. The third preset value T3 is greater than the first preset value T1 and less than the second preset value. T2;

S401: If the temperature T collected by the temperature sensor 10 is greater than the first preset value T1 and not greater than the third preset value T3, when the brightness L of the display screen 20 is less than the first preset brightness L1, the control fan 30 does not start. ;

S403: When the brightness L of the display screen 20 is not less than the first preset brightness L1, the control fan 30 is operated at the second rotation speed R2 that is less than the first rotation speed R1.

As such, a fan 30 control strategy that displays the temperature of device 100 and the brightness of display 20 is achieved.

It can be understood that if the temperature T collected by the temperature sensor 10 is greater than the first preset value T1 and not greater than the third preset value T3 (T1 < T ≤ T3), when the brightness L of the display screen 20 is less than the first preset brightness When L1 (L<L1), it indicates that there is no risk of heat dissipation and the temperature of the display screen 20 rises slowly, and the user touches no discomfort. At this time, the control fan 30 is not activated, so that the display device 100 is operated without noise; when the display screen 20 When the brightness L is not less than the first preset brightness L1 (L ≥ L1), the display device 100 needs to perform heat dissipation. At this time, the control fan 30 is operated at the second rotation speed R2 that is smaller than the first rotation speed R1 to ensure heat dissipation of the display device 100. At the same time, it also takes into account the user's listening experience. The third predetermined value T3 can be set to any value between 57 ° C and 59 ° C, such as 57 ° C, 59 ° C or 57 ° C to 59 ° C, preferably 58 ° C. In one example, the brightness L of the display screen 20 is expressed as a percentage, for example, the highest brightness is 100%. The range of the first predetermined brightness L1 may be set to any value between 75% and 85%, such as 75%, 85% or 75%-85%, preferably 80%. The second rotational speed R2 may range from 800 to 1200 r/min, for example any value between 800 r/min, 1200 r/min or 800-1200 r/min, preferably 1000 r/min.

Referring to FIG. 3, in some embodiments, the control method includes the following steps:

S402: If the temperature T collected by the temperature sensor 10 is greater than the third preset value T3 and not greater than the second preset value T2, when the brightness L of the display screen 20 is less than the second preset brightness L2, the control fan 30 does not start. ;

S404: When the brightness L of the display screen 20 is not less than the second preset brightness L2 and less than the first preset brightness L1, the control fan 30 is operated at the second rotation speed R2;

S406: When the brightness L of the display screen 20 is not less than the first preset brightness L1, the control fan 30 is operated at the first rotation speed R1.

It can be understood that if the temperature T collected by the temperature sensor 10 is greater than the third preset value T3 and not greater than the second preset value T2 (T3 < T ≤ T2), when the brightness L of the display screen 20 is less than the second preset brightness When L2 (L<L2), it indicates that there is no risk of heat dissipation and the temperature of the display screen 20 rises slowly, and the user does not feel uncomfortable. At this time, the control fan 30 is not activated, so that the display device 100 is operated without noise; when the display 20 is When the brightness L is not less than the second preset brightness L2 and less than the first preset brightness L1 (L2 ≤ L < L1), the display device 100 needs to perform heat dissipation, and at this time, the fan 30 is controlled to have a second rotation speed smaller than the first rotation speed R1. The R2 operation ensures the heat dissipation of the display device 100 while also taking into account the user's hearing experience; when the brightness L of the display screen 20 is not less than the first preset brightness L1 (L ≥ L1), there is a risk of heat dissipation and the display screen 20 The temperature rises faster, and at this time, the control fan 30 is operated at the first rotation speed R1 to ensure the heat dissipation effect of the display device 100. The range of the second predetermined brightness L2 may be set to any value between 45% and 55%, for example 45%, 55% or 45%-55%, preferably 50%.

In the embodiment of the present application, the control method of the fan 30 first determines the temperature T collected by the temperature sensor 10 to determine the brightness L of the display screen 20, thereby controlling the rotation speed of the fan 30. In another embodiment, the control method of the fan 30 may be to first determine the brightness L of the display screen 20 and determine the temperature T collected by the temperature sensor 10, thereby controlling the rotation speed of the fan 30.

In some embodiments, the first rotational speed R1 can be the highest rotational speed of the fan 30.

It can be understood that when the heat dissipation risk of the display device 100 is large, the rotation speed of the control fan 30 is the maximum rotation speed R1, thereby further ensuring the heat dissipation performance.

In some embodiments, the control method includes the step of adjusting the input voltage of the fan 30 to control the rotational speed of the fan 30.

It can be understood that the rotational speed of the fan 30 is proportional to the input voltage, and the rotational speed of the fan 30 can be adjusted by adjusting the input voltage of the fan 30. The first rotational speed R1 and the second rotational speed R2 correspond to one input voltage, respectively. The input voltage corresponding to the first rotational speed R1 is, for example, 5V, and the input voltage corresponding to the second rotational speed R2 is, for example, 3.3V.

In some embodiments, the control method includes the step of transmitting a pulse width modulated signal to the fan 30 to control the rotational speed of the fan 30.

It can be understood that transmitting a pulse width modulation signal (PWM) of different duty ratios to the fan 30 can control the rotational speed of the fan 30. The pulse width modulation signals of different duty ratios correspond to different fan 30 rotation speeds, and the rotation speed of the fan 30 can be flexibly controlled.

In certain embodiments, temperature sensor 10 includes a thermistor, an embedded temperature sensor, or a temperature diode.

It can be understood that the temperature sensor 10 can select a thermistor, an embedded temperature sensor or a temperature diode according to requirements. Specifically, the thermistor can be an on-board thermistor, the embedded temperature sensor can be an embedded temperature sensor of the core chip, and the temperature diode can be a connector type temperature diode.
