For example, if the magnitude of voltage that processing module 10 is received by voltage transformation module 12 is 700mv, then processing module 10 can be chosen the temperature value (namely 48 DEG C) of a correspondence by temperature lookup table 131, if and the magnitude of voltage that processing module 10 is received by voltage transformation module 12 is 480mv, then processing module 10 can be chosen the temperature value (namely 70 DEG C) of a correspondence by temperature lookup table 131.It follows that selected temperature value is considered as the operational temperature of display device 1 by processing module 10, thereby determine the operational temperature of display device 1.
Again, for example, assume that processing module 10 is 48 DEG C according to the temperature value selected by magnitude of voltage and above-mentioned preset value is 45 DEG C.Processing module 10 judges that selected temperature value is more than or equal to described preset value, processing module 10 is chosen the backlight adjusted value of a correspondence (namely dutycycle is 75%) by backlight look-up table 132, then the luminous intensity of backlight module is adjusted according to this backlight adjusted value through pulse width modulation (PulseWidthModulation is called for short PWM) mode.
As from the foregoing, when the operational temperature of display device 1 is more than or equal to a preset value, the backlight adjusted value that processing module 10 meeting foundation backlight look-up table records is to adjust the backlight intensity of display device 1, and the rising of the operational temperature along with display device 1, processing module 10 can downgrade the backlight intensity of display device 1 gradually, to avoid causing the damage of display device 1, thereby extend the length of service of display device 1.It is noted that, when the operational temperature of display device 1 is increased to a particular value (as shown in table 2 71 DEG C), processing module 10 can maintain the backlight intensity of display device 1 at a basic value, thereby ensuring that user still can check the picture shown by display device 1 under low backlight intensity.

In step S214, processing module 10 performs a sleep program, to stop being chosen temperature value by temperature lookup table 131 in a Preset Time (such as 2 seconds, but the embodiment of the present invention was not limited thereto), then performs step S212.Palpus one is mentioned that, because the operational temperature of display device 1 can't be constantly in the state of variation, therefore processing module 10 foundation magnitude of voltage repeatedly can be avoided by choosing temperature value in temperature lookup table 131 by performing described sleep program, and cause unnecessary power consumption.
In step S215, the temperature value of up-to-date acquirement can be temporarily stored into memory module 13 by processing module 10, thereby updates the temperature value kept in memory module 13, then performs step S216.
In step S216, processing module 10 judges that whether the operational temperature of display device 1 is more than or equal to a preset value, namely judges that whether the temperature value kept in step S215 is more than or equal to described preset value (being such as 45 DEG C).When processing module 10 judges the operational temperature of display device 1 less than described preset value, perform step S217.Otherwise, when processing module 10 judges the operational temperature of display device 1 more than or equal to described preset value, perform step S218.
In step S217, processing module 10 adjusts the backlight intensity of display device 1 according to a backlight value or maintains the backlight intensity of display device, then performs step S214.In detail, if user changes the backlight value preset by above-mentioned input module, then processing module 10 can change the backlight intensity of display device 1 according to the setting (that is, according to the backlight value after changing) of user.On the other hand, if user does not change default backlight value, then processing module 10 adjusts according to the backlight value not changed or maintains the backlight intensity of display device, then performs step S214, after a Preset Time, to return back to step S212.
In step S218, processing module 10 according to the operational temperature of described display device 1 by a backlight look-up table is chosen a backlight adjusted value, and according to the backlight intensity of selected backlight adjusted value adjustment display device, then perform step S214, after a Preset Time, to return back to step S212.
Correlative detail about each step of the backlight intensity method of adjustment of display device 1 describes in detail in above-mentioned Fig. 1 embodiment, pardons not repeating at this.
Should be noted that at this, each step of Fig. 2 embodiment only for convenience of description need, the embodiment of the present invention is not using each step order to each other as the restrictive condition implementing each embodiment of the present invention.
