Receive sensing result.According to the physical quantity that environment circuit for detecting 150 is detected, processing circuit 130 send out integrated regulation order to
Picture adjustment circuit 130 carrys out whole at least one display parameters of adjustment picture.For example (but not limited to), according to ring
The ambient brightness (physical quantity) that border circuit for detecting 150 is detected, processing circuit 130 send out integrated regulation order and are adjusted to picture
Circuit 130, dynamically to adjust the whole brightness (display parameters) for the picture that display panel 110 is presented.
Fig. 6 is to illustrate that the flow of the display parameters method of adjustment of display device 500 is shown according to another embodiment of the present invention
It is intended to.Please refer to Fig. 3, Fig. 5 and Fig. 6.Step S410 shown in Fig. 6, step S420, step S430 and step S440 are referred to figure
4 related description is analogized, and so it will not be repeated.After step S410, processing circuit 130 can carry out step S610, to judge
User 10 whether touch-control screen (display panel 110).When processing circuit 130 judges the (display of 10 touch-control of user screen
Panel 110) when, processing circuit 130 can carry out step S620, with judge user 10 whether ongoing operation screen (display surface
Plate 110).When processing circuit 130 judges 10 ongoing operation of user screen (display panel 110), processing circuit 130 can be with
Step S630 is carried out, (such as environment is bright to go the physical quantity of environment of detecting display device 500 by environment circuit for detecting 150
Degree).According to the physical quantity that environment circuit for detecting 150 is detected, processing circuit 130 sends out integrated regulation life in step S640
It enables to picture adjustment circuit 130, to adjust the display parameters of overall picture.After completing step S640, step S420, step S430
It can be performed with step S440.
For example, the ambient brightness detected according to environment circuit for detecting 150, processing circuit 130 is in step S640
In send out integrated regulation order to picture adjustment circuit 130, the brightness (display parameters) of overall picture is dynamically adjusted to
One brightness value (such as 50%).Eye tracks circuit 140 can shoot the eyes 11 of user 10, to obtain eye position letter
Cease 141 (step S420).When the eyes 11 of user 10 watch the picture that display panel 110 is presented, according to eye position
Information 141, processing circuit 130 may determine that eyes 11 watch the concern post-11.2 (step in display panel 110
S430).In step S440, processing circuit 130 can be by the bright of the regional area 111 comprising concern post-11.2 in picture
Degree (display parameters) is increased from first brightness value (such as 50%) as the second brightness value (such as 100%), and will be in picture
In the brightness (display parameters) in other regions maintain first brightness value.Regional area 111 is not reviewed in eyes 11
After (that is, sight 12 leaves regional area 111), processing circuit 130 can by the brightness (display parameters) of regional area 111 from
Second brightness value is recalled to first brightness value.
It is worth noting that, in different application situations, picture adjustment circuit 120, processing circuit 130 and/or eyes
The correlation function of tracking circuit 140 can utilize general programming language (programming languages, such as C or C+
+), hardware description language (hardware description languages, such as Verilog HDL or VHDL) or other conjunction
Suitable programming language is embodied as software, firmware or hardware.Can perform the programming language of the correlation function can be arranged to
Any of computer can access media (computer-accessible medias), such as tape (magnetic
Tapes), semiconductor (semiconductors) memory body, disk (magnetic disks) or CD (compact disks,
Such as CD-ROM or DVD-ROM), or internet (Internet), wire communication (wired can be passed through
