After showing at least one of pixel brightness value (such as B11, B12, B21, B22) of picture data DFD, according to read pixel intensity
It is worth the luminance that (such as B11, B12, B21, B22) accordingly sets backlight module 135.
Furthermore, it is understood that display picture data can be read in keyboard controller 133 when backlight module 135 is monochromatic display
One of pixel brightness value (such as B11, B12, B21, B22) of DFD, to set the luminance of backlight module 135；Keyboard
The pixel brightness value (such as B11, B12, B21, B22) of the part of display picture data DFD can be read in controller 133, and calculates institute
The average brightness and coloration average value of the pixel brightness value (such as B11, B12, B21, B22) of reading, to set backlight module 135
Luminance；Alternatively, keyboard controller 133 can be read all pixel brightness values of display picture data DFD (such as B11, B12,
B21, B22) and the average brightness and coloration average value of all pixel brightness value (such as B11, B12, B21, B22) are calculated, with
Set the luminance of backlight module 135.Wherein, above-mentioned implementation detail can refer to shown in Fig. 2 implementation, then no longer superfluous at this
It states.
On the other hand, when backlight module 135 is multicolor displaying, keyboard controller 133 is reading display picture data DFD
It is corresponding according to pixel brightness value (such as B11, B12, B21, B22) after all pixel brightness values (such as B11, B12, B21, B22)
Pixel brightness value (such as B11, B12, B21, B22) is divided into multiple groups by display position, accordingly to determine in backlight module 135
Luminescence unit (such as K1~K4, K11, K21) a other luminance.Wherein, above-mentioned implementation detail can refer to the reality of Fig. 3~5
Shown in applying, it will not be described in detail here.
Fig. 6 is the flow chart of the keyboard back light setting method of the computer system of an embodiment according to the present invention.It please refers to
Fig. 6, in the present embodiment, the keyboard back light setting method of computer system include the following steps.In step S610, it can read
It is stored in the display picture data of Installed System Memory, wherein display picture data is for setting picture shown by display.Then,
In step S620, the luminance of the backlight module of setting keyboard can be carried out according to display picture data.Wherein, step S610
And the sequence of S620 is for illustrating, the embodiment of the present invention is not limited.Also, the details of step S610 and S620 can refer to
