Operation.Therefore, in some embodiments, controller processor 60 can be included in processor 18 and/or single process
In circuit, and memory 62 can be included in memory 20 and/or individually in tangible non-transitory computer-readable medium.This
Outward, in some embodiments, controller 58 can be included in (for example as time schedule controller) in source electrode driver 34, or
Single discrete circuit can be arranged to, be located at common inside the shell (or detached with display 12 outer with display 12
In shell).Additionally, controller 58 can be that digital signal processor (DSP), special IC (ASIC) or other process are single
Unit.
Additionally, controller processor 60 can be with one or more tangible non-transient machine readable medias (such as memory 62)

Controller 58 can receive the information relevant with the operation of display 12, and can generate can be used for control display picture
The output 64 of the operation of element 40.For example, controller 58 can receive the instruction of the refresh rate to display 12, or can receive to display
The instruction (for example, data being completely written to the frequency in display picture element 40 array of display) of the expectation refresh rate of device 12.
The instruction of the expectation refresh rate of the refresh rate of display 12 or display 12 can be in the variable refresh rate (VRR) of display 12
The refresh rate of indication display 12 is reduced to 30Hz or even more low-frequency part from such as 60Hz.Therefore, controller 58 can
Instruction based on the VRR to display 12 come change its output 64.Similarly, for example, if the refresh rate of display 12 is by controlling
Device 58 processed controls, then controller 58 can instruction Ji Yu (for example receiving from processor 18) expectation VRR to display 12
To change the output 64 of oneself.Output 64 can be used for generating the control in order to control display picture element 40 in such as source electrode driver
Signal processed.
In order to produce output 64, the instruction receiving the expectation VRR to display 12 can for example be stored by controller 58
In memory 62.Controller 58 may further determine that the expectation VRR (and/or current VRR of display 12) of display 12 to calculate
(determination) generates display to be imported into as emission control (EM) output of output 64, source electrode driver 34 using this output

It is transferred to the EM signal of display picture element 40 by source electrode driver 34.Can be determined and generate this EM output by controller 58, with
The artifact relevant with the VRR of display 12 is generated and is optionally minimized.
Fig. 7 shows the display that can be controlled by the output 64 (directly or via source electrode driver 34) from controller 58
One embodiment of device pixel 40.The display picture element 40 of Fig. 7 includes：Contactor TFT 50, it can be that low drain is established by cable
Close transistor such as oxide TFT (such as indium gallium zinc oxide TFT)；Storage 52；LED 54；And high mobility
TFT 66 and 68 (such as low temperature polycrystalline silicon (LTPS) TFT) stacked structure, it is as the driving TFT of LED 54.Stacking in Fig. 7
High mobility TFT 66 and 68 can be described as LTPO structure with combining of oxide TFT 50, and this makes the display using this LTPO structure
Device 12 can improve effect when driving using VRR.In addition, as illustrated, high mobility TFT 66 is (as can light
TFT described EM signal) can be received as grid control signal, therefore enable controller 58 directly (or via scanner driver
Indirectly) control the luminous of display picture element 40.
Similarly, Fig. 8 shows and can be controlled by the output 64 (directly or via source electrode driver 34) of controller 58
Display picture element 40.The display picture element 40 of Fig. 8 includes：Contactor TFT 50, it can be that Low dark curient switching transistor is all
As oxide TFT (such as indium gallium zinc oxide TFT)；Storage 52；LED 54；And high mobility TFT 66,68 He
70 (such as low temperature polycrystalline silicon (LTPS) TFT) stacked structure, it is as the driving TFT of LED 54.The high mobility of stacking in Fig. 8
TFT 66,68 and 70 combines alternatively referred to as LTPO structure with oxide TFT's 50, and this makes the display using this LTPO structure
12 can improve effect when driving using VRR.In addition, as illustrated, high mobility TFT 66 and 70 is (as can light
One or more of) TFT can receive described EM signal as grid control signal, therefore enable controller 58 directly (or
Via scanner driver indirectly) control the luminous of display picture element 40.
Sometimes, when driving, via VRR discussed above, the different refresh rate generating for display 12, VRR's
The change of display 12 brightness can occur at the transition point between different refresh rates.Fig. 9 illustrates curve Figure 72, and this illustrates utilization
The curent change of LED 54 after the refresh rate change of the display 12 of LTPS display picture element 40.As illustrated, display 12
Refreshed with first rate (such as 60Hz) in time, as shown in point 74.The electric current 76 of LED 54 is (for example because capacitor 52 leaks electricity
And) consume, till putting another refreshing of the display 12 at 74, this generates when display 12 is refreshed with first rate
The shown average voltage 78 of LED 54.Drive with the VRR of display 12 and combine, the refresh rate of display 12 can change at point 80
Become so that display 12 is refreshed with the second speed (such as 30Hz) in time, as shown in point 82.The electric current 76 of LED 54 is (for example
Because capacitor 52 leaks electricity) consume, till putting another refreshing of the display 12 at 82, this generates when display 12
The shown average voltage 84 of LED 54 when being refreshed with the second speed.If more than 1%, (this is referred to as the mean flow rate change of display
VRR index), then at point 80, the change of average voltage 78 to average voltage 84 can cause visual artifact.
For LTPO display 12, the leakage of the voltage being stored on capacitor 52 can be made to be down to using oxide TFT 50
Minimum degree, thus farthest reducing the effect shown in Fig. 9, this is because constant voltage is applied on capacitor 52 will
The LED 54 of display 12 is made to keep constant current and constant instantaneous brightness in the period that entirely lights of frame.Although however, having
Constant instantaneous brightness, the mean flow rate of each frame of display 12 still can be changed due to different refresh rates, and due to
Many reasons and make VRR index reduce.For example, every a line display picture element 40 the sending out LED 54 in display 12 can be directed to
Light disables one or more row times (for small-size display 12, the row time can be in the range of 30 μ s to 40 μ s), so that
LED 54 initializes and display picture element 40 is programmed into suitable gray level.Therefore, within the set time of 1 μ s, for
The 60Hz refresh rate of display 12, luminous can be deactivated 60 times, and the 1Hz refresh rate for display 12, luminous only can be stopped
With once (that is, disable the luminous speed generally mated of LED 54 with the refresh rate with display 12 via EM signal
Rate is realizing).Additionally, with respect to higher refresh rate (such as 60Hz), under relatively low refresh rate (such as 30Hz, 1Hz etc.), LED sends out
The less deactivation of light will increase the average current of each frame.Situation discussed above is shown in Figure 10.
Figure 10 is the sequential chart of display 12 luminance difference illustrating to drive using VRR.As illustrated, when display 12 utilizes
During the first refresh rate (such as 60Hz), data wire 46 can the first refresh rate transmission scanning signal 88.Similarly, when being transferred to
When the EM signal of display picture element 40 is mated with the refresh rate of display 12, EM signal 90 is with identical with the frequency of scanning signal 88
Frequency by chopping.This makes to generate the LED current 92 for LTPO display 12.
Similarly, when display 12 utilizes the second refresh rate (such as 1Hz), data wire 46 can the second refresh rate transmission
Scanning signal 94.Similarly, when the EM signal being transferred to display picture element 40 is mated with the refresh rate of display 12, EM believes
Numbers 96 with the frequency identical frequency with scanning signal 94 by chopping.This makes to generate the LED electricity for LTPO display
Stream 98.In addition although the instantaneous brightness 100 being generated by LED current 92 and LED current 98 is equal, but due in LED current 92
Corresponding with the low ebb of EM signal 90 pulse " zero " value, the mean flow rate of display is with first refresh rate of Figure 10 and the second brush
When new rate refreshes and unequal.
Although additionally, having constant instantaneous brightness, the mean flow rate of each frame of display 12 can be change, this
It is due to being made presence between luminous TFT 66 and/or 70 activation and the activation of LED 54 postpone (such as LED 54 by EM signal
Do not immediately turn on).In addition in the expected electric capacity at anode terminal or parasitic capacitance, LED 54 also has the electricity of oneself
Hold, this electric capacity needs to be charged by the electric current of display picture element 40.Only when the anode voltage of LED 54 exceedes cut-in voltage,
Just start to light.Additionally, for relatively low gray level, the usual very little of electric current (for example in the range of pA), so LED 54
Anode charging interval and overall response time can be in the range of milliseconds.Additionally, the LED 54 response time behavior of change can be due to becoming
The gray level changed, LED 54 stack, temperature etc. and affect to some extent each frame average current so that the luminosity response time increase
Plus.
Controller 58 can be used for overcoming the mentioned above mean flow rate that may result in display 12 to change between each frame
Potential problems.For example, as shown in sequential Figure 102 of Figure 11, controller 58 can produce output 64, and this output is for example passed through to select
The refreshing of frequency LED 54 being lighted with the EM signal for transmission to display picture element 40 especially determining and display 12
Rate optionally disassociation.As illustrated, when display 12 utilizes the first refresh rate (such as 60Hz), data wire 46 is permissible
First refresh rate transmission scanning signal 88.Similarly, controller 58 can make EM signal mate with the refresh rate with display 12
Speed be transferred to display picture element 40 so that EM signal 90 with the frequency identical frequency with scanning signal 88 by chopping.
This makes to generate the LED current 92 for LTPO display 12.
However, controller 58 may further determine that when the second refresh rate (such as 1Hz) is used as display 12 by display 12
The part that VRR drives, this will make data wire 46 transmit scanning signal 94 with the second refresh rate.When display 12 utilizes the second brush
During new rate, controller 58 can adjust the transmission of EM signal so that EM signal 104 is with the frequency pulse different from the second refresh rate
(for example, frequency is that first frequency is identical with the frequency of prior scans signal 88).This makes to generate the LED of LTPO display 12
Electric current 106, wherein by LED current 92 and LED current 106, the instantaneous brightness generating and mean flow rate are equal, as shown in figure 11.
Therefore, low refresh rate (such as 1Hz, 30Hz etc.) and higher refresh rate are for example followed in order to ensure LED 54 lights
There is under (such as 60Hz) identical ON/OFF response time and duration, display picture element can will be used for by controller 58
The rate selectivities vein of the earth impulsive motion to determine for the EM signal.Even if display floater refreshes under low refresh rate (e.g., less than 60Hz)
(data charging intervals of new images for example to be loaded) reduce, and this pulse of EM signal still can occur.Further, since big portion
Point power consumption and display 12 refresh about and unrelated with the luminous driving of LED 54, so using the EM that can be selected by controller 58
Signal can provide constant average current in VRR driving period, remain simultaneously and drive, for VRR, the power consumption benefit making to contribute.
Additionally, controller 58 can make EM signal different from the signal shown in Figure 11.Controller can make EM signal with more than aobvious
Show frequency (the such as 120Hz, 240Hz etc.) chopping of device 12 refresh rate.Additionally, controller 58 can make shown in EM signal and Figure 11
Signal different in pulse width.For example, as shown in sequential Figure 108 of 12 in figures, controller 58 can make EM signal pulse 110
Width for example gradually change in the framework using pulsewidth modulation (PWM), with adjust further from LED current 112 generate
Brightness, thus change the refresh rate of display 12.
Equally, Figure 13 shows the display picture element 40 with other Fig. 7 of switch 114.The display picture element of Figure 13
40 can be used for adjusting VRR index further.For example, switch 114 can be used for making LED 54 discharge and adjust discharge time, and this makes
VRR index can more specifically be adjusted.In fact, controller 58 can generate discharge signal as output 64 a part so that
Discharge signal can be couple to the grid of switch 114 with the activation of controlling switch 114.Discharge signal can be selected by controller 58
Frequency.For example, as shown in sequential Figure 116 of 14 in figures, controller 58 can make discharge signal 118 with EM signal 104 identical
Frequency is by chopping.Similarly, controller 58 can make discharge signal 118 with the frequency different from EM signal 104 by chopping, all
As the factor (such as multiple or fraction) as EM signal 106.
