Description
Technical field
The present invention relates to field of display technology more particularly to a kind of flexible displays and its driving method.
Background technique
GOA (Gate Driver on Array, array substrate row driving) technology is will be as the TFT of gate switch circuit
(Thin Film Transistor, thin film transistor) is integrated in array substrate, to save original be arranged in battle array
Grid-driving integrated circuit part outside column substrate reduces the cost of product in terms of material cost and processing step two.
GOA technology is that (Thin Film Transistor-Liquid Crystal Display, thin film field-effect are brilliant by current TFT-LCD
Body pipe liquid crystal display) a kind of common gate driving circuit technology of technical field, manufacture craft is simple, has good answer
Use prospect.The function of GOA circuit is specifically included that using the high level signal of lastrow grid line output in shift register cell
Capacitor charging recycle the high level signal of next line grid line output to realize multiple so that current row grid line exports high level signal
Position.
Demand with people to portable display device increases increasingly, and flexible display technologies become the aobvious of great competitive advantage
Show one of technology.The big advantage of the one of flexible display technologies is can to increase display area in this way without increasing with foldability
Big equipment volume, it is very portable.The folding mode designed at present has upper and lower doubling or three foldings, left and right doubling or three foldings.After folding,
It can become main display surface generally towards upper display surface, display surface directed downwardly does not show content to save power consumption.
For the design scheme of up and down folding, after folding, display surface upward is used to show picture, and display directed downwardly
Face will not then show content, to save power consumption.The initial signal of GOA circuit is generally since the first row, via displacement deposit electricity
Road generates the output signal being displaced line by line down.Or initial signal is inputted from last line, it is past via displacement register circuit
It is upper to generate the output signal being displaced line by line.And signal is controlled by forward scan and reverse scan controls signal and cooperates control defeated
Signal forward scan or reverse scan out.Such design has a drawback in Folding display: after flexible apparatus folding,
GOA signal still can transmit down since the first row, or up transmit since last line.In this way, after folding, being
The display surface for making upward shows picture, and display surface directed downwardly does not show picture, integrated circuit (Integrated Circuit,
IC) end must input considerable 0 gray scale data signal.On the other hand, after folding, it is only necessary to the GOA work of display surface upward
The GOA of work, display surface directed downwardly can not have to running, but the GOA of display surface directed downwardly is still working at this time, causes power consumption
Waste.

Further, it is also possible to the working frequency of first scanner section 21 and the second scanner section 22 is not reduced, but it is aobvious to promote described first
Show the picture refreshing frequency of area 11 and the second viewing area 12 picture refreshing frequency whole for flexible display panels 1 under expansion mode
Twice, the display of high picture refreshing frequency has larger application in terms of 3D display.
Preferably, the displacement register circuit 2 is GOA circuit, and the switch module 23 is thin film transistor (TFT), the film
The grid of transistor is control terminal, and source electrode is input terminal, is drained as output end.
Referring to Fig. 2, the quantity of the displacement register circuit 2 is two in the second embodiment of the present invention, it is divided into
Two opposite sides of the flexible display panels 1 namely the flexible display are bilateral driving framework, remaining is and first embodiment
Identical, details are not described herein again.
It can be in addition, in other embodiments of the invention, between first viewing area 11 and the second viewing area 12
Equipped with folding region, first viewing area 11 and the second viewing area 12 can be turned down along the folding region.
In conclusion the flexible display will scan initial signal by opening the present invention provides a kind of flexible display
It closes module and is linked into the afterbody displacement deposit unit of the first scanner section and the first order displacement deposit unit of the second scanner section
In, and two groups of forward and reverse scan control signals are set, the first scanner section is controlled respectively and the second scanner section carries out forward direction and sweeps
It retouches or reverse scan, to pass through the cooperation realization flexible display of switch module and two groups of forward and reverse scan control signals
The first viewing area is individually shown when folding, the second viewing area is individually shown or the first and second viewing areas are shown simultaneously, can be subtracted
Power consumption when few Folding display, while the refreshing frequency of picture can also be increased if necessary, extend flexible display application model
It encloses.The present invention also provides a kind of driving methods of flexible display, it is possible to reduce power consumption when Folding display, while if necessary
The refreshing frequency of picture can also be increased, extend flexible display application range.
The above for those of ordinary skill in the art can according to the technique and scheme of the present invention and technology
Other various corresponding changes and modifications are made in design, and all these change and modification all should belong to the claims in the present invention
Protection scope.
