As shown in figure 1, the display device includes touch control display panel 1, touch-control driving chip 2, display driver chip 3
With MCU control chips 4.The touch-control driving chip 2 be connected to the touch control display panel 1 and the MCU control chips 4 it
Between, the MCU control chips 4 control the touch-control driving chip 2 to input touching signals, institute to the touch control display panel 1
Touch-control driving chip 2 is stated by the touch control operation feedback of the information of acquisition to the MCU control chips 4, the MCU control chips 4
The current position of touch on the touch control display panel 1 is determined according to the touch control operation information.The display driver chip 3
It is connected between the touch control display panel 1 and the MCU control chips 4, the MCU control chips 4 drive to the display
Dynamic chip 3 inputs display data signal, and the display picture of touch control display panel 1 is driven by the display driver chip 3.
Wherein, as shown in Fig. 2 the driving method of the display device in the present embodiment includes step：
S1, the touch control operation acquisition of information position of touch according to user to the touch control display panel.Specifically, refer to
Fig. 1, the touch control operation information obtained first by touch-control driving chip 2, then again the MCU control chips 4 according to the touch-control
Operation information determines the current position of touch P on the touch control display panel 10.In the present embodiment, the touch-control driving
Connected between chip 2 and the MCU control chips 4 by I2C buses.
S2, the touch control display panel divided by focus vision area and non-line-of-sight focal zone according to the position of touch.
Specifically, refering to Fig. 1, in the present embodiment, panel division module 41, the panel subregion are provided with the MCU control chips 4
Module 41 is according to the position of touch P0, the touch control display panel 1 is divided into focus vision area 11 and non-line-of-sight focal zone
12；Wherein, the focus vision area 11 is corresponding covers the position of touch P0, the non-line-of-sight focal zone 12 then refers to described touch
The region outside the focus vision area 11 is removed in control formula display panel 1.Wherein, the quantity in the focus vision area 11 according to
Position of touch P0Quantity determine, when there is multiple position of touch P0And spacing it is larger when, then can be in the touch control display panel
1 marks off multiple focus vision areas 11.
S3, input display data signal, are driven the focus vision area to be shown with higher first resolution, driven
The non-line-of-sight focal zone is shown with relatively low second resolution.Here, it is higher and it is relatively low be comparatively, i.e. institute
State second resolution and be less than the first resolution.Specifically, driven refering to Fig. 1, the MCU control chips 4 to the display
Chip 3 inputs display data signal, and the display picture of touch control display panel 1 is driven by the display driver chip 3, its
In, the display driver chip 3 drives the focus vision area 11 to be shown with first resolution, drive the non-line-of-sight to gather
Burnt area 12 is shown with second resolution.
In the present embodiment, as shown in figure 1, passing through shifting between the display driver chip 3 and the MCU control chips 4
The dynamic communication of Industry Processor Interface (Mobile Industry Processor Interface, MIPI) 5 connection, the MIPI
Interface 5 includes main channel (Master) 51 and is additionally provided with from passage (Slave) 52, the MCU control chips 4 for controlling
The main channel 51 and the data channel control module 42 of the data transmission state from passage 52.Wherein, described in driving
Focus vision area 11 show when, the data channel control module 42 control the main channel 51 and it is described from passage 52 simultaneously to
The display driver chip 3 inputs display data signal, and now, the display driver chip 3 drives the focus vision area 11
Shown with first resolution.When driving the non-line-of-sight focal zone 12 to show, the data channel control module 42 is controlled
System only inputs display data signal from the main channel 51 to the display driver chip 3, and described be in from passage 52 is closed
State, now, the display driver chip 3 drive the non-line-of-sight focal zone 12 to be shown with second resolution.
The display device and its driving method of example offer is performed as described above, during display picture, according to position of touch
P0Display panel is divided into focus vision area 11 and non-line-of-sight focal zone 12.Normally, the visual characteristic due to human eye in itself：
That is for people when using display device (such as mobile phone) is touched, the finger that sight gets used to focusing on positive touch manipulation on a display screen is attached
Near subregion (the i.e. foregoing focus vision area 11 marked off), so, for the use of mobile phone, often it is concerned with
The display effect in the region of finger manipulation, and the video effect outside human eye focusing range is just less important.Dividing
After region, for the focus vision area 11 of human eye concern, it is driven to be shown with higher first resolution, it is ensured that human eye
The picture quality of region-of-interest；And for the not high region of the human eye attention rate outside focus vision area, it is driven with relatively low
Second resolution is shown, reduces the power consumption of display screen.Thus, in the display device and its driving method, integrally aobvious
Show the visual experience that human eye is not interfered with effect, and can enough preferably reduces the power consumption of display device, extends stand-by time.
Specifically, the first resolution is the highest resolution that the touch control display panel 1 can be shown, described
Two resolution ratio be the touch control display panel 1 it is compatible and less than the highest resolution any one display differentiate
Rate.For example, the first resolution is WQHD (2560 × 1440RGB), then the second resolution can be 1920 ×
1080RGB, 1366 × 786RGB, 1280 × 720RGB etc..
It should be noted that herein, such as first and second or the like relational terms are used merely to a reality
Body or operation make a distinction with another entity or operation, and not necessarily require or imply and deposited between these entities or operation
In any this actual relation or order.Moreover, term " comprising ", "comprising" or its any other variant are intended to
Nonexcludability includes, so that process, method, article or equipment including a series of elements not only will including those
