The depressed position of flexible display panels, and the resolution ratio of flexible display panels is updated according to depressed position.
According to one embodiment of present invention, the first transistor T1i in each detection unit is arranged on corresponding pixel
In unit.
Specifically, in an embodiment of the present invention, pressure-sensitive double-gated transistor MAi in resolution update device can be set
In GOA (Gate Driver On Array, array base palte raster data model) unit, the first transistor T1i may be provided at AA areas
(Active Area, array of display area).Further, when the row scanning of flexible display panels is using shift register, pressure
Quick double-gated transistor MAi may be provided in corresponding shift register, and the first transistor T1i may be provided at corresponding pixel cell

Pole is used as folded signal output end G (i)-Sen and the control pole phase for the first transistor T1i being arranged in respective pixel unit
Even.
When flexible display panels are not folded, the work schedule of shift register is as shown in Figure 3 a：
First stage：When signal input Inputi does not have signal input, although the first clock signal input terminal
High level occurs in the clock signal that CLK1i is provided, but is due to that pull-up node PUi points keep low level, and transistor M9 is in
Off state, so signal output end G (i) is low level.
Second stage：When signal input Inputi has signal input, transistor M1 conductings so that pull-up node
PUi is changed into high level, transistor M9 conductings from low level, but is due to that now the first clock signal input terminal CLK1i is provided
Clock signal is low level, so signal output end G (i) is still low level.
Phase III：When the first clock signal input terminal CLK1i clock signals provided are changed into high level from low level,
Because pull-up node PUi has been high level, so transistor M9 is turned on, signal output end G (i) can export high level.
Because electric capacity C1 and transistor M9 itself parasitic capacitance is present, with raising for signal output end G (i) current potentials, pull-up
Node PUi current potential can be raised further, so that transistor M9 unlatching is bigger, further improve transistor M9 charging
Ability, it is ensured that the charging of pixel cell.When pull-up node PUi is high level, transistor M5 and M7 conducting so that pull-down node
PDi keeps low level.
Fourth stage：When the first clock signal input terminal CLK1i clock signals provided are changed into low level, and letter is resetted
Number input Reseti is high level, and transistor M2 and M11 conducting, pull-up node PUi and signal output end G (i) are drawn
Low, output is closed.And after pull-up node PUi is pulled low, transistor M5 and transistor M7 shut-offs, meanwhile, in second clock
Under signal input part CLK2i high level effect, transistor M4 and transistor M6 conductings, pull-down node PDi are charged as high level,
Transistor M3 and transistor M10 conductings so that signal output end G (i) maintains low level state, to reduce signal
Output end G (i) noise.
It should be noted that because pressure-sensitive double-gated transistor MAi is needed when compression and pull-up node PUi are high level
It can turn on, so when pressure-sensitive double-gated transistor MAi is not pressurized, even if pull-up node PUi is high level, pressure-sensitive double-gated transistor
MAi will also be off state, the output of folded signal output end G (i)-Sen no signals.
And when pressure-sensitive double-gated transistor MAi is pressurized, the work schedule of shift register as shown in Figure 3 b, wherein, first
It is identical when stage and fourth stage are not pressurized with pressure-sensitive double-gated transistor MAi, and in second stage, when pull-up node PUi is
During high level, under pressure and pull-up node PUi collective effect, pressure-sensitive double-gated transistor MAi conductings, but when being due to first
Clock signal input part CLK1i is low level, so folded signal output end G (i)-Sen is low level, at the first transistor T1i
In off state.And in the phase III, because pull-up node PUi is high level, and the first clock signal input terminal CLK1i is also
High level, so now folded signal output end G (i)-Sen is changed into high level, the first transistor T1i conductings, control unit 20
The public electrode Vcomi of pixel cell voltage will be obtained, then control unit 20 is defeated according to the voltage and the first clock signal
Enter to hold the sequential of the clock signal of CLK1i offers can be accurately positioned the depressed position of flexible display panels, and according to compression position
Put and the resolution ratio of flexible display panels is updated.
Therefore, by above-mentioned example, pressure-sensitive double-gated transistor only need to be added on the basis of original GOA unit,
So pressure, and the height electricity of the clock signal of the first clock signal input terminal offer are bent in the row GOA unit by the external world
During flat arrival, folded signal output end output high level further opens the first transistor that AA areas connect public electrode so that
The Voltage Feedback of the public electrode of the row is to outside SOC, and outside SOC combines the clock letter that the first clock signal input terminal is provided
Number sequential and the phase relation of signal of folded signal output end output can judge compression line number, so as to orient flexibility
The folding position of display panel, and then notify display driver to get new resolution ratio, to adapt to current flexible display panels
Show area.

The second of transistor MAi, which extremely corresponds to, to be connected, and reset circuit is used to carry in pull-down node PDi or reset signal input Reseti
When the reset signal of confession is low level, pressure-sensitive double-gated transistor MAi the second pole is pulled down to low level signal input VGL and carried
The low level of confession, so that the first transistor T1i is off state.
Yet further, as shown in figure 4, reset circuit includes second transistor T2i and third transistor T3i, second is brilliant
Body pipe T2i the first pole is extremely connected with the second of pressure-sensitive double-gated transistor MAi, second transistor T2i the second pole and low level

T3i the first pole is extremely connected with the second of pressure-sensitive double-gated transistor MAi, third transistor T3i the second pole and low level signal
Input VGL is connected, and third transistor T3i control pole is connected with pull-down node PDi.
Specifically, as shown in figure 5, reset circuit may be provided in corresponding shift register, when flexible display panels not
When being folded, the work schedule of shift register is just no longer described here, and when flexible display panels are folded, the displacement is posted
The work schedule of storage is identical with the work schedule shown in Fig. 3 b, and its difference is：
In fourth stage, when the first clock signal input terminal CLK1i clock signals provided are changed into low level, and reset
When signal input part Reseti is high level, transistor M2, transistor M11 and third transistor T3i conductings, pull-up node PUi,
Signal output end G (i) and folded signal output end G (i)-Sen are pulled low.And it is brilliant after pull-up node PUi is pulled low
Body pipe M5 and transistor M7 shut-offs, while under second clock signal input part CLK2i high level effect, transistor M4 and crystalline substance
Body pipe M6 is turned on, and pull-down node PDi is charged as high level, transistor M3, transistor M10 and second transistor T2i conductings so that
Signal output end G (i) and folded signal output end G (i)-Sen maintain low level state, to reduce signal output
Hold G (i) and folded signal output end G (i)-Sen noise.So can be when the row pixel cell be chosen, first crystal
Pipe T1i is turned on, and when the row pixel cell is not selected, the first transistor T1i is constantly in off state, so that control
Unit 20 processed obtains a square-wave signal, and the position being folded fast and accurately is oriented according to the square-wave signal, effectively anti-
Only the problem of the first transistor, which misleads, to be occurred positioning by mistake.
Therefore, by above-mentioned example, corresponding crystalline substance need to only be increased on the basis of original GOA unit and AA areas
Body pipe, is used with reference to the characteristics of pressure-sensitive double-gated transistor, and to clock signal, without arranging that detection is passed again on the outside of screen
Sensor, you can realize the real-time accurate renewal of resolution ratio, i.e. can be as accurate as each line position and put, and can be in each frame pair
