Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
The embodiment of the present invention provides a kind of driving method of display panel, and display panel includes multiple pictures arranged in arrays Plain unit, each pixel unit include N number of sub-pixel, and N is positive integer.It is shown in image the described method includes: controlling every frame, often Two row pixel units are a sub- drive cycle, the sub-pixel and next line pixel list of the last one charging in previous row pixel unit The display color of the sub-pixel to charge at first in member is identical, and the sub-pixel charging that the last one in previous row pixel unit charges After unlatching, sub-pixel charging clock signal is continued until after the sub-pixel charging complete that next line pixel unit charges at first Low and high level switching is carried out again.Control the sub-pixel and next sub- drive cycle of the last one charging of previous sub- drive cycle The display color of the sub-pixel to charge at first is identical, and the sub-pixel of the last one charging of previous sub- drive cycle charges and opens Afterwards, sub-pixel charging clock signal be continued until after sub-pixel charging complete that next sub- drive cycle charges at first again into The switching of row low and high level.Every N frame shows that image is a drive cycle；Wherein in each drive cycle, each frame shows that image drives The display color for the sub-pixel that dynamic period the first row pixel unit charges at first respectively corresponds N number of sub-pixel of each pixel unit Display color, each frame shows the display color difference for the sub-pixel that sub- the second row of the drive cycle pixel unit of image charges at first The display color of N number of sub-pixel of corresponding each pixel unit.
The driving method of display panel provided by the invention shows image with N frame as a drive cycle, and every frame shows image In, every two rows pixel unit is a sub- drive cycle.In each sub- drive cycle, the last one in previous row pixel unit charges Sub-pixel and next line pixel unit in the display color of sub-pixel that charges at first it is identical, and in previous row pixel unit most After the sub-pixel charging of the latter charging is opened, sub-pixel charging clock signal is continued until that next line pixel unit fills at first Low and high level switching is carried out again after the sub-pixel charging complete of electricity, therefore can save the height of charging clock signal in the ranks Level switching times.Control the sub-pixel of the last one charging and the filling at first for next sub- drive cycle of previous sub- drive cycle After the display color of the sub-pixel of electricity is identical, and the sub-pixel charging of the last one charging of previous sub- drive cycle is opened, son Pixel charging clock signal carries out height after being continued until the sub-pixel charging complete that next sub- drive cycle charges at first again Low level switching, therefore the low and high level switching times of charging clock signal in the ranks can also be saved.Averagely arrive every a line picture In plain unit charging process, it is possible to reduce the switching of 2 charging clock signal low and high levels, therefore display panel can be reduced Power consumption.
As shown in Fig. 2, if sub-pixel fills after the sub-pixel charging unlatching that the last one in previous row pixel unit charges Electrical clock signal be continued until next line pixel unit charge at first sub-pixel charging complete after carry out low and high level again Switching；After the sub-pixel charging complete that the last one charges so in previous row pixel unit, since sub-pixel charging clock is believed It number is not turned off, it is electric that the charging voltage for the sub-pixel that the last one in previous row pixel unit charges can be always maintained at original charging Straightening, which is changed to charging clock signal by high level, switchs to low level.And in two row pixel unit of front and back between other sub-pixels by Low level is changed in the low and high level switching for normally carrying out charging clock signal, therefore in charging clock signal high level dress When, charging voltage can be declined slightly.Therefore according to above-mentioned driving method, when the sub-pixel of some display colors does not omit charging The low and high level of clock signal switches, therefore will appear charging voltage decline；The sub-pixel of some display colors is due in a son The low and high level of charging clock signal is omitted between two row of front and back of drive cycle or between former and later two sub- drive cycles Switching, therefore charging voltage remains unchanged, so the sub-pixel of different display colors will appear the uneven problem of charging, to go out Existing color offset phenomenon.
The embodiment of the present invention controls every N frame and shows that image is a drive cycle, and in each drive cycle, each frame display figure The display color of the sub-pixel to be charged at first as sub- drive cycle the first row pixel unit respectively corresponds the N number of of each pixel unit The display color of sub-pixel, each frame show the display face for the sub-pixel that sub- the second row of the drive cycle pixel unit of image charges at first Color respectively corresponds the display color of N number of sub-pixel of each pixel unit.Such as each pixel unit includes 3 sub-pixels, point Not Wei display color be red sub-pixel, the sub-pixel that display color is green and sub-pixel that display color is blue.Every 3 Frame shows that image is a drive cycle, and first frame shows the sub-pixel that the sub- drive cycle the first row pixel unit of image charges at first Display color be red, the second frame shows the display of sub-pixel that the sub- drive cycle the first row pixel unit of image charges at first Color is green, and third frame shows that the display color for the sub-pixel that the sub- drive cycle the first row pixel unit of image charges at first is Blue.First frame shows that the display color for the sub-pixel that sub- the second row of the drive cycle pixel unit of image charges at first is blue, Second frame shows the display color for the sub-pixel that sub- the second row of the drive cycle pixel unit of image charges at first for red, third frame The display color for the sub-pixel that display sub- the second row of the drive cycle pixel unit of image charges at first is green.Therefore first frame is aobvious The display color of the sub-pixel of the adjacent unlatching of two row pixel units is blue, two son driving of front and back before and after diagram picture drive cycle The display color of the sub-pixel of period adjacent unlatching is red, therefore first frame shows that the charging clock signal saved in image is high Low level includes red and blue without the sub-pixel display color of switching.Second frame is shown two before and after the sub- drive cycle of image The display color of the sub-pixel of the adjacent unlatching of row pixel unit is red, the sub-pixel of the adjacent unlatching of the sub- drive cycle in front and back two Display color is green, therefore the second frame shows sub- picture of the charging clock signal low and high level saved in image without switching Plain display color includes red and green.Third frame shows the son of the adjacent unlatching of two row pixel units before and after the sub- drive cycle of image The display color of pixel is green, and the display color of the sub-pixel of the adjacent unlatching of the sub- drive cycle in front and back two is blue, therefore the Three frames show in image the charging clock signal low and high level saved without the sub-pixel display color of switching include green and Blue.So display color is that red, green and blue the corresponding of sub-pixels omission are omitted in the ranks in a drive cycle Charging clock signal low and high level switching number be it is identical, i.e., due to omit charging clock signal low and high level switching, The effect of the sub-pixel charging voltage of different display colors on the whole is identical.So in statistical significance, each display The charging situation of the sub-pixel of color is identical, therefore the embodiment of the present invention can be on the basis of reducing display panel power consumption, also Display effect can be improved, avoid the occurrence of color offset phenomenon caused by the sub-pixel charging unevenness of different display colors.
The above are the core concepts of the driving method of display panel provided by the invention, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described.Based on the embodiments of the present invention, Without making creative work, every other embodiment obtained belongs to this to those of ordinary skill in the art Invent the range of protection.
