The diagrammatic cross-section of kind display panel.With reference to Fig. 1-Fig. 3, which includes:
Multiple luminous zones 10 and driving chip 20；
Each luminous zone 10 includes multiple pixel units 11, and each pixel unit 11 includes luminescence unit 111 and driving electricity
Road 112；The output end of driving circuit 112 is electrically connected with the first electrode 31 of luminescence unit 111, and driving circuit 112 is for driving
Luminescence unit 111 shines；Driving circuit 112 includes the first power supply signal input PVDD；
Driving chip 20 includes multiple first power supply signal output ends 21, each driving circuit 112 of same luminous zone 10

This, significantly increases the power consumption of Organic Light Emitting Diode, to improve the power consumption of display panel.
By taking 2t1c driving circuit as an example, the driving current I=K (VDD-V of luminescence unit 111data-Vth1)2, wherein Vdata
For the display drive signals of driving circuit, VthFor the on state threshold voltage of luminescence unit 111,μ is current-carrying
Transport factor, CoxFor gate oxide capacitance (capacitor on gate oxide unit area), W/L is the breadth length ratio for driving transistor,
For same luminescence unit 111, K is fixed value.VDD generallys use a fixed numbers in the prior art, by changing Vdata
To change driving current I, display of the realization to different brightness.
The present embodiment changes driving current I by reducing VDD, realizes the display to different brightness.Specifically, Mei Yifa
Power consumption P=(VDD-VSS) the * I1 in light area 10, wherein VDD is the first power supply signal, and VSS is the current potential of second electrode, and I1 is same
The electric current summation of each pixel unit 11 in one luminous zone 10, for same display brightness, the value of I1 is fixed, and VSS is fixed electricity
Therefore position for same display brightness, shows the brightness by reducing VDD, compared to the prior art in by adjusting display
Driving signal Vdata shows the brightness, can effectively reduce the power consumption of luminous zone 10.
The present embodiment by by the first power supply signal input PVDD of each driving circuit 112 of same luminous zone 10 and drive
Same first power supply signal output end 21 electrical connection of dynamic chip 20, so that when each pixel unit 11 in same luminous zone 10 is aobvious
When showing same display brightness, the size of the first power supply signal VDD of the luminous zone 10 can be reduced according to display brightness, to drop
The overall power of the low luminous zone 10, reduces the power consumption of display panel.
Optionally, driving chip 20 is used to show that same pre-display is bright when each pixel unit 11 in same luminous zone 10
Degree, and pre-display brightness be lower than current display brightness when, reduce the first power supply signal of the luminous zone 10 according to pre-display brightness
Size.
Wherein, the brightness for the picture that each pixel unit 11 is currently displaying in current display brightness, that is, luminous zone 10, in advance
The brightness of display brightness, that is, next frame picture to be shown.When the pre-display brightness of each pixel unit in a certain luminous zone 10 is identical

Next frame brightness to be shown (pre-display brightness) is b, and b < a1, b < a2, b < a3, b < a4, b < a5 and b < a6, then drives at this time
The first power supply signal VDD=v2, v2 < v1 can be arranged according to the size of b in dynamic chip 20.6 pixel units in the luminous zone 10
Total power consumption P2=(v2-VSS) * i2 when 11 equal display brightness b, 6 pixel units 11 distinguish display brightness in the luminous zone 10
Total power consumption P1=(v1-VSS) * i1 when a1, a2, a3, a4, a5 and a6.Wherein, i1 and i2 is the drive of 6 pixel units 11
Streaming current and, due to b < a1, b < a2, b < a3, b < a4, b < a5 and b < a6, then 6 pixel units show respectively a1, a2, a3, a4,
The driving current when driving current of a5 and a6 is respectively less than display brightness b is less than, then i2 < i1.Again due to v2 < v1, P=(VDD-
VSS) * I1, therefore P2 < P1, i.e., when the pre-display brightness of each pixel unit in a certain luminous zone 10 is identical and shows lower than current
When brightness, the pre-display brightness is shown by directly reducing corresponding first power supply signal in luminous zone 10, reduces the hair
The overall power in light area 10, to reduce the power consumption of display panel.
It should be noted that when the current display brightness of each pixel unit 11 is all the same in luminous zone 10, it can be only
The display of pre-display brightness is realized by reducing the first power supply signal VDD, without adjusting to display drive signals Vdata
It is whole.

Each pixel unit 10 that driving chip 20 is also used to work as in same luminous zone 10 shows same pre-display brightness, and pre-
When display brightness is lower than current display brightness, according to pre-display brightness adjustment display drive signals VdataSize.
Specifically, working as the current display brightness part of each pixel unit 11 in 10 in luminous zone not mutually simultaneously as same
Corresponding same first power supply signal in luminous zone 10, therefore can be driven by the display of driving chip adjustment member pixel unit 11
Signal Vdata.
Illustratively, if in a certain luminous zone 10 including 6 pixel units 11, the current display brightness of each pixel unit 11
Respectively a1, a2, a3, a4, a5 and a6, corresponding display drive signals be vdata1, vdata2, vdata3, vdata4,
Vdata5 and vdata6, corresponding first power supply signal VDD=v1.Wherein, a1=a2 ≠ a3 ≠ a4 ≠ a5 ≠ a6, then vdata1
=vdata2 ≠ vdata3 ≠ vdata4 ≠ vdata5 ≠ vdata6.6 11 next frame of pixel unit brightness to be shown are (pre- aobvious
Show brightness) it is b, and b < a1, b < a2, b < a3, b < a4, b < a5, b < a6.It then can be according to vdata1 (vdata2) and pre- aobvious
Show brightness b combination formula I=K (VDD-Vdata-Vth1)2Determine the corresponding first power supply signal v2 of brightness b, and by the luminous zone 10

It is intended to, with reference to Fig. 8, display device 100 includes the display panel 200 that any embodiment of that present invention provides.Display device 100 can be with
Equipment is shown for mobile phone, tablet computer and smartwatch etc..
The present embodiment additionally provides a kind of driving method of display panel, and Fig. 9 is provided in an embodiment of the present invention a kind of aobvious
The schematic diagram for showing the driving method of panel, with reference to Fig. 9, this method comprises:
Step 610 obtains pre-display image.
Step 620, when each pixel unit in the same luminous zone shows same pre-display brightness, according to institute
State the size that pre-display brightness reduces the first power supply signal of the luminous zone.
The present embodiment is bright according to pre-display by showing same pre-display brightness when each pixel unit in same luminous zone
Degree reduces the size of the first power supply signal of the luminous zone, the overall power of the luminous zone is reduced, to reduce display panel
Power consumption.
Optionally, this method further include: when each pixel unit in the same luminous zone shows same pre-display brightness,
And the pre-display brightness be lower than current display brightness when, reduce the first power supply of the luminous zone according to the pre-display brightness
The size of signal.
