Screen protection system and method of an electronic device

A screen protection method of an electronic device, the electronic device comprising a display screen, one or more first temperature sensors and a second temperature sensor, the method comprising:

• defining a screensaver time for the electronic device, setting a standard temperature difference value of temperatures for the electronic device, and setting an allowable number of the one or more first temperature sensors;
• recording a first operation temperature of the electronic device detected from each of the one or more first temperature sensors, and recording a first ambient temperature detected from the second temperature sensor, when the display screen is activated to be in an active state;
• starting timing time once the electronic device is not operated, and storing a duration of the timer temporarily and resetting the timer once the electronic device is being operated;
• obtaining a second operation temperature of the electronic device detected from each of the one or more first temperature sensors, and obtaining a second ambient temperature detected from the second temperature sensor, upon the condition that the duration is equal to the screensaver time;
• determining whether the electronic device is currently being held by a hand of a user according to the first operation temperatures, the first ambient temperature, the second operation temperatures and the second ambient temperature, the electronic device being determined to be held by a hand of the user, if a first difference value is less than or equal to the standard temperature difference value and at least one allowable number of second difference values are less than or equal to the standard temperature difference value, and the electronic device being determined not to be held by a hand of the user, if the first difference value is less than or equal to the standard temperature difference value and at least one allowable number of the second difference values are greater than the standard temperature difference value, wherein the first difference value represents a difference between the first ambient temperature and the second ambient temperature, and each of the second difference values represents a difference between each of the first operation temperatures and each of the corresponding second operation temperatures;
• controlling the display screen to be in an inactive state upon the condition that the electronic device is not being held by a hand of the user;
• and
• maintaining the display screen continually to be in an active state upon the condition that the electronic device is being held by a hand of the user.

A non-transitory storage medium storing a set of instructions, the set of instructions capable of being executed by a processor of an electronic device, cause the electronic device to perform a screen protection method of the electronic device, the electronic device comprising a display screen, one or more first temperature sensors and a second temperature sensor, the method comprising:

• defining a screensaver time for the electronic device, setting a standard temperature difference value of temperatures for the electronic device, and setting an allowable number of the one or more first temperature sensors;
• recording a first operation temperature of the electronic device detected from each of the one or more first temperature sensors, and recording a first ambient temperature detected from the second temperature sensor, when the display screen is activated to be in an active state;
• starting timing time a duration once the electronic device is not operated, and storing the duration temporarily and resetting the timer once the electronic device is being operated;
• obtaining second operation temperatures of the electronic device detected from the one or more first temperature sensors, and obtaining a second ambient temperature detected from the second temperature sensor, upon the condition that the duration is equal to the screensaver time;
• determining whether the electronic device is being held by a hand of a user, according to the first operation temperatures, the first ambient temperature, the second operation temperatures and the second ambient temperature, wherein the electronic device being determined to be held by a hand of the user, if a first difference value is less than or equal to the standard temperature difference value and at least one allowable number of second difference values are less than or equal to the standard temperature difference value, and the electronic device being determined not to be held by a hand of the user, if the first difference value is less than or equal to the standard temperature difference value and at least one allowable number of the second difference values are greater the standard temperature difference value, wherein the first difference value represents a difference between the first ambient temperature and the second ambient temperature, and each of the second difference values represents a difference between each of the first operation temperatures and each of the corresponding second operation temperatures;
• controlling the display screen to be in an inactive state, upon the condition that the electronic device is not being held by a hand of the user;
• and
• maintaining the display screen continually to be in the active state, upon the condition that the electronic device is being held by a hand of the user.
