As it was previously stated, display 18 may include VCOM driver.For example, the embodiment that Fig. 7 shows display 18.Aobvious Show that device 18 includes receiving the effective coverage 52 of the VCOM signal from VCOM amplifier 56 and 58 at public side 54.VCOM is put Big device 56 receives feedback 60 and 62 as negative feedback with 58 from effective coverage 52 side relative with public side 54.VCOM amplifies Device 56 and 58 receives feedback 60 and 62 by feedback resistor 64 and 66.VCOM amplifier 56 and 58 is also by rheostat 68 and 70 receiving feedback, and in this case, these rheostats 68 and 70 are defeated by VCOM amplifier 56 and 58 respectively Go out end to connect to the negative input end of VCOM amplifier 56 and 58.For the embodiment illustrating, near effective coverage 52 with VCOM voltage in the other parts of the VCOM voltage in the distal region 72 of the relative side of public side 54 and effective coverage 52 Different.Specifically, the reason cause this phenomenon is that there is trace between distal region 72 and the other parts of effective coverage 52 Resistance difference.

Fig. 8 shows curve Figure 73 of the VCOM voltage observation in distal region 72.The abscissa 74 of curve Figure 73 is right Should be in the time, and vertical coordinate 76 corresponds to the VCOM voltage level in distal region 72.This voltage level is around burning voltage 78 fluctuations, after write time section and/or the VCOM level that should settle out of period.However, as illustrated, stable region The speed that voltage level in domain 80 settled out before next write time section is slower, and/or at all stably to stably Voltage 78.

Fig. 9 shows the embodiment 81 of display 18, and wherein effective coverage 52 is divided into region 82,84 and 86, makes Obtain each region to be processed in the way of different from other regions.In other words, rheostat 68 and 70 may depend on Position that source gate line is positioned in effective coverage 52 and be driven to varying level.The embodiment 81 illustrating includes three Region, but some embodiments may include one, two, three, four, five or more regions.In addition, though region 82nd, the 84 and 86 whole width across effective coverage extend, but some embodiments can horizontally and vertically zoning.For example, Figure 10 illustrates the embodiment 88 of display 18, and wherein effective coverage 52 is divided into 15 regions.Specifically, effective coverage 52 It is divided into region 90,92,94,96,98,100,102,104,106,108,110,112,114,116 and 118, these regions It is collectively referred to as region 90 to 118.Rheostat 68 and 70 can be based on position in effective coverage 52 for the active gate with difference Resistance driven.For example, the look-up table being stored in memorizer may indicate which kind of electricity the position based on region should set Block water flat.Region 90 to 118 can be of the same size or can with region from public side 54 increasingly away from and taper into.Change Sentence is talked about, and nearer region (such as region 114,116 and 118) can be more than region (such as region 90,92 and 94) farther out.Make For substitute, region 90 to 118 can with region from public side 54 increasingly away from and become larger.

Figure 11 shows and can be disposed to reduce VCOM stabilization time section, reduction VCOM fluctuation and/or to regard by electronic equipment 10 The flow chart feeling the process 120 of artifact.For example, instruction can be stored in storage device 28 and be executed by processor 12.? In some embodiments, at least some of these steps step can be carried out within hardware.Process 120 includes activating display At least one pixel gate line (frame 122).This processor 12 determines effective gate line in the effective coverage of display 18 Position (frame 124).For example, this processor 12 can determine that in the first pixel column that valid pixel is located in first row pixel.Place Reason device 12 also determines that this position corresponds to which the region (frame in multiple (such as 15) region of effective coverage of display 18 126).For example, when valid pixel is located in the first row and first row, valid pixel can be located in region 90 to 118 first In region 90.

Then resistance value corresponding with this region (frame 128) searched by processor 12.For example, processor 12 can check storage dress Put the look-up table in 28, to determine resistance corresponding with this region.For example, first area 90 can have relatively high resistance value, And the 15th region 118 then has relatively low resistance value.This processor 12 subsequently makes rheostat be driven to lookup The resistance (frame 130) arriving.Rheostat can be rheostat 68 and/or the rheostat 70 of Fig. 7 and Fig. 9.Variable Resistance makes each region because other electrology characteristics of resistance of traces, parasitic character and/or display 18 are different with not Tongfang Formula is processed, to reduce display artifact and/or to increase show uniformity.Therefore, different VCOM driver resistance are subsequently used To drive display 18.

Although said process discusses determination location of pixels and region to search resistance value, in some embodiments, Resistance value can correspond directly to pixel so that only need to know that specific pixel just be enough to determine resistance value.For example, each pixel Resistance value can be stored in look-up table.Therefore, in such embodiment, resistance can be determined using effective pixel positions Value, and pixel region need not be determined.In addition or alternatively, have because the concrete time (such as 5 μ s) may correspond to write The concrete pixel of certain position, therefore can use the sequential of frame.In other words, processor 12 can undefined position, and can serve as Substitute, the timing settings variable resistance based on frame in.

Although additionally, discussion above discusses and determining position using processor and sets rheostat, electronics Some embodiments of equipment 10 can be come in implementation procedure 120 using other hardware such as gate driver integrated circuit (GDIC) At least some step.In addition, in some electronic equipments, one or more processors 12 can be comprised in display 48, Or can be with displays separated.

Figure 12 shows the embodiment party of curve Figure 150 of the stabilization time section in each region in exemplary area 90 to 118 Case.The vertical coordinate 154 of curve Figure 150 corresponds to VCOM voltage, and abscissa 156 corresponds to the time.Curve Figure 150 also shows Go out the group 158,160,162,164 and 166 in one or more of respective expression corresponding region 90 to 118 region.For example, group 158 may correspond to region 90,92 and 94.Similarly, group 160 may correspond to region 96,98 and 100, and group 162 may correspond to region 102nd, 104 and 106, group 164 may correspond to region 108,110 and 112, and organize 166 and may correspond to region 114,116 and 118. Curve Figure 150 also show the assessment time period 168, and at the assessment time period 168, comparable VCOM voltage is for analysis.As Shown in figure, group 166 is generally stable, and the stabilization time in region generally with region from public side 54 increasingly away from and increase Plus.

Another kind of mode reducing stabilization time is to reduce ITO sheet resistance.Curve Figure 170 shown in Figure 13 correspond to Lower display：Its ITO sheet resistance is bigger than the ITO sheet resistance of the display 18 for formation curve Figure 150.Curve Figure 170 Abscissa 172 correspond to the time, and vertical coordinate 174 correspond to VCOM voltage.As illustrated, with regard to 176,178,180,182 For each group in 184 these groups, stabilization time of its VCOM voltage with respect to its each self-corresponding group 158,160, 162nd, 164 and 166 generally it is enhanced.Specifically, the VCOM voltage shown in curve Figure 170 is in assessment time period 186 internal ratio VCOM voltage shown in curve Figure 150 of Figure 12 faster settles out.However, during practical operation, due to there is physical restriction, Therefore can not unrestrictedly reduce ITO sheet resistance.For example, this physical restriction can based on manufacturing capacity, economic feasibility, And/or other considerations.

In some cases, for reducing VCOM stabilization time, some embodiments may include supplementary features.For example, Figure 14 Show the display 190 including effective coverage 192, wherein effective coverage 192 is divided into by different VCOM amplifier circuits The two VCOM regions 194 and 196 driving.Specifically, VCOM region 194 is driven by VCOM amplifier circuit 202, and VCOM Region 196 is driven by VCOM amplifier circuit 204.

VCOM amplifier circuit 202 includes amplifier 206 and resistor 208 and 210.In some embodiments, electricity Resistance device 208 and/or 210 may be based on position in region 194 for the valid pixel and changes the rheostat of resistance.For example, Valid pixel from amplifier 206 farther out when, the setting value of resistance can be higher than when valid pixel be closer to amplifier 206 Value.Similar to VCOM amplifier circuit 202, VCOM amplifier circuit 204 includes amplifier 212 and resistor 214 and 216. Due to the VCOM amplifier circuit 202 and 204 physically potential valid pixel closer to farthest side, therefore VCOM amplifier Circuit 202 and 204 can have less trace (correspondingly, having relatively high impedance) between them.Except other factors, The resistance reducing makes VCOM stabilization time reduce.

Figure 15 shows the curve chart of the embodiment of stabilization time section in each region in exemplary area 90 to 118 220.The abscissa 222 of curve chart 220 corresponds to the time, and vertical coordinate 224 corresponds to VCOM voltage.Curve chart 220 also shows Go out the group 226,228,230,232 and 234 in one or more of respective expression corresponding region 90 to 118 region.For example, group 226 may correspond to region 90,92 and 94.Similarly, group 228 may correspond to region 96,98 and 100, and group 230 may correspond to region 102nd, 104 and 106, group 232 may correspond to region 108,110 and 112, and organize 234 and may correspond to region 114,116 and 118. Curve chart 220 also show the assessment time period 236, at the assessment time period 236, can be from burning voltage by VCOM voltage evaluation 238 start to change.As illustrated, VCOM voltage faster settles out than in curve Figure 150 and 170 in graph 220.Change Sentence is talked about, and VCOM voltage faster settles out during or after the assessment time period 236 and and/or fluctuates less.

Figure 16 shows the display 240 including effective coverage 241, and wherein effective coverage 241 is divided into two regions 242 and 244.Each region is driven by different amplifier circuits.Specifically, region 242 via trace 248 by VCOM amplifier Circuit 246 drives.Equally, region 244 is driven by VCOM amplifier circuit 250 via trace 252.In display 240, VCOM Amplifier circuit 246 and 250 is positioned in the same side of display 240.Although display 240 includes compared to display 190 More VCOM traces, but not in the both sides of effective coverage 241, there is the space for printed circuit board (PCB) in display 240 When, it is usable in the arrangement used in display 240.In addition, in order to compensate for being couple to VCOM amplifier circuit 250 The additional traces in region 244, the size in region 244 is smaller than the size in region 242.In other words, the chi in region 242 and 244 Very little ratio can be more than 1.The precision ratio of every kind of type of display can ghost effect based on display and/or other displays special Property calculating, to determine the ideal ratio needed for the stabilization time that specific display reduces its type of display.

VCOM amplifier circuit 246 includes amplifier 254 and feedback resistor 256 and 258.As described above, feedback electricity The rheostat that resistance device 256 and/or 258 may be based on position in region 242 for the valid pixel and changes.Similar to VCOM Amplifier circuit 246, VCOM amplifier circuit 250 includes amplifier 260 and feedback resistor 262 and 264.

Figure 17 shows the curve chart of the embodiment of stabilization time section in each region in exemplary area 90 to 118 270.The abscissa 272 of curve chart 270 corresponds to the time, and vertical coordinate 274 corresponds to VCOM voltage.Curve chart 270 also shows Go out the group 276,278,280,282 and 284 in one or more of respective expression corresponding region 90 to 118 region.For example, group 276 may correspond to 90,92 and 94 these three regions.Similarly, group 278 may correspond to region 96,98 and 100, and group 280 can correspond to In region 102,104 and 106, organize 282 and may correspond to region 108,110 and 112, and organize 284 and may correspond to region 114,116 With 118.Curve chart 270 also show the assessment time period 286, at the assessment time period 286, can be from steady by VCOM voltage evaluation Determine voltage to start to change.As illustrated, under VCOM voltage is faster more stable than in curve Figure 150 and 170 in curve chart 270 Come.In other words, VCOM voltage faster settles out during or after the assessment time period 286 and and/or fluctuates less

The embodiment that Figure 18 shows display 290.Display 290 is divided into 3 regions：Region 292, region 294 and region 296.Region 292,294 and 296 is driven by different VCOM amplifier circuits 298,302 and 306.Illustrate In embodiment, the region 292 near VCOM amplifier circuit 298,302 and 304 is more than other regions.By divide from The farthest one or more regions of VCOM amplifier circuit 298,302 and 306 and the trace that includes can be less than for entirely activity At least a portion not being located in region 292 of display or display 290 only exists script in the case of a solid area Trace to be used.Therefore, by reducing trace, impedance can substantially be reduced, thus reducing VCOM stabilization time section, to increase The uniformity of big display 290 outward appearance.

Although the Illustrative Embodiment of display 290 includes three regions, display 290 may include more than three area Domain.For example, display 290 may include four, five, six or more regions.In some embodiments, region 292 can It is divided into two or more regions.In addition or alternatively, region 294 and 296 can be divided by different way.Example As the gross space that can cover region 294 and 296 is divided into two or more regions.The mode dividing these regions can be water Certain combination of square formula, vertical mode or both modes.The dimensional ratios in these regions and/or quantity can be directed to each The ghost effect based on each corresponding display group/display for the display/display group and/or other electrology characteristics are Lai really Fixed.

VCOM amplifier circuit 298 includes amplifier 310 and resistor 312 and 314.In some embodiments, electricity Resistance device 312 and/or 314 may be based on position in region 292 for the valid pixel and changes the rheostat of resistance.For example, Valid pixel from VCOM amplifier circuit 298 farther out when, the setting value of resistance can higher than in valid pixel closer to VCOM Value during amplifier circuit 298.

Similar to VCOM amplifier circuit 298, VCOM amplifier circuit 302 includes amplifier 316 and resistor 318 With 320, and VCOM amplifier circuit 306 includes amplifier 322 and resistor 324 and 326.In some embodiments, One or more of resistor 318,320,324 and 326 resistor may be based on valid pixel in region 294 and 296 Position and change the rheostat of resistance.For example, valid pixel from VCOM amplifier circuit 302 and 306 farther out when, resistance Setting value can higher than valid pixel closer to value during VCOM amplifier circuit 302 and 306.

Due to the company between VCOM region and VCOM amplifier circuit 302 and 306 in VCOM region 294 and 296 Connect less and trace shorter (for example, only around the side of effective coverage 291), therefore VCOM amplifier circuit 302 and 306 exists Can have less trace (correspondingly, there is relatively high impedance) between them.As described above, except other factors, reducing Resistance so that VCOM stabilization time is reduced.

The flow chart that Figure 19 shows the embodiment of the process 350 for operating display.Process 350 includes determination to be had The subregion (frame 352) of the residing pixel in the pixel region in the effective coverage of display of effect pixel.Pixel region corresponds to In the multiple pixels being driven by certain the VCOM amplifier circuit in multiple VCOM amplifier circuits.This subregion includes pixel region Multiple pixel bands at different distances with corresponding VCOM amplifier in domain.In other words, each region can benefit from Driven with the different resistance values of one or more feedback resistors of the feedback circuit in VCOM amplifier circuit by VCOM amplifier Dynamic.

At least based on position in subregion for the valid pixel, determine one or more feedback electricity of VCOM amplifier circuit The resistance value (frame 354) of resistance device.Then by the resistance of one or more feedback resistors be set as determined by resistance value (frame 356).Once resistance value is set, just can be utilized with using one or more feedback resistors and determined by resistance value picture The VCOM amplifier circuit in the region of element is driving VCOM (frame 358).

It should be appreciated that said process can be implemented using hardware, software or certain combination of both.For example, can use Executing the instruction being stored in memorizer, these instructions are configured to held for general processor and/or graphic process unit Computing device process 350 is made during row.

However, it is extremely strong to represent that the VCOM being carried out based on fixed panel position tuning is likely to be of using the less overall situation Position specificity.Additionally, VCOM tuning may be difficult to compensation panel and arriving the grid of panel and recoil increment and temperature change.Separately Outward, for large-sized panel, the DC distribution of VCOM may be less uniformly so that be that the bigger distribution of panel is more complicated.And And, due to there are recoil difference and other uneven factors in panel, therefore face plate edge change in location may be larger.

Therefore, in addition to above-mentioned VCOM tuning or alternatively, can be initiateed based on VFB_CLK and frame and be controlled by DAC System, to adjust VREF, is just being written of the locations/regions of data with determination.Figure 20 shows the display including effective coverage 52 Embodiment, this effective coverage 52 is made up of the multiple pixels being logically grouped in region 82,84 and 86.Effective district Domain 52 receives VCOM voltage 402 from VCOM amplifier 404.The D/C voltage of VCOM voltage 402 can be for often row pixel using whole The distribution of display 18 and change.VCOM voltage 402 is controlled using reference voltage (VREF) 406.This reference voltage can use Receive the digital to analog converter (DAC) 408 of digital signal 410 and/or additional signal (such as VFB_CLK pulse and frame initial pulse) And be conditioned.Digital signal can derive from timing controller (TCON) 412.Timing controller 412 with can be programmed by TCON412 Communicated based on the logical block 414 in region.In some embodiments, TCON412 can use built-in integrated circuit (I2C) Agreement connects or serial peripheral interface (SPI) bus is programmed, with via the logical block 414 based on region by data is activation To DAC 308.In some embodiments, each region 82,84 and 86 can have corresponding separate logic components so that single Specific region is exclusively used in based on the logical block 414 in region.Alternatively, be may correspond to many based on the logical block 414 in region In a single region (for example whole panel), now different regions has different settings.In some embodiments, may be used To some settings that retrieve or value be able to be stored in memorizer 416 by the logical block 414 based on region and/or TCON 412, For controlling the regional in effective coverage 52.

In some embodiments, the VCOM of the distal part 418 of effective coverage 52 may be with the nearside of effective coverage 52 The VCOM of part 420 is proportional.This ratio amplification of gained (and at amplifier 404) can be by including resistor 424 and 426 Voltage control 422 controls.In some embodiments, these resistors can be variable, and uses in above process TCON 412 and/or be controlled based on the logical block 414 in region.In addition or alternatively, enter effective coverage 52 The VCOM voltage of various pieces can be manipulated using VREF and be controlled.

Figure 21 shows and can be used for adjusting the embodiment to control the sequential chart 430 of VCOM 402 for the VREF 406.As figure Shown, Frame is initiated using frame start signal 432.In some embodiments, frame start signal 432 can be for indicating The pulldown signal of 434 Frames is initiated when drop-down.Alternatively, frame start signal 432 can be pull-up signal.Sequential chart 430 is also Show the row clock 436 for data 438 being write the pixel column in effective coverage 52.Although the embodiment bag illustrating Include horizontal synchronization, but some embodiments may also comprise vertical synchronization, be now applied to capable all discussions and be changed into being applied to row. VREF voltage 406 uses TCON 412 and/or logical block 414 based on region (and frame start signal 432 and VFB_CLK Signal 440) it is set.VFB_CLK signal 440 is used for instruction and just executes write to new region.For example, VFB_CLK signal 440 In pulse 442 instruction have handed over region pixel write.For example, before pulse 442, data may be written into always Pixel in region 82, and after pulse 442, data can be written into the pixel in region 84.For guarantee data by correct (and As one man) write, the change of VREF 406 can be made synchronous with the change of the Transition edges 444 of data 438.For in effective distribution Every line use VCOM DC level the distribution based on by-line, can at least partially through adjust VREF 406 according to line Lai Drive effective coverage 52.

Figure 22 shows the curve chart 450 of the VCOM 402 and VREF406 of embodiment during the work of effective coverage 52. Curve chart 450 includes line 452 corresponding with VCOM 402 line 454 corresponding with VREF406 and line corresponding with data 438 456.As illustrated, the time of transition in corresponding to line 456 corresponding with data 438 for the line 452 corresponding with VREF 406 Offset downward at 458.VREF 406 skew leads to VCOM 402 to offset, as shown in line 452.Specifically, VREF 406 is higher Value when, VCOM 402 is the first value 460, and when VREF 406 declines, VCOM 402 is down to second value 462.It may be noted that The stabilization time section of VCOM 402 does not change because VREF 406 offsets.Side-play amount can be controlled by feedback circuit Transient Dynamics And/or limit.In addition, in some embodiments, determine that the method for VCOM DC desired value can be：By entering to display To determine every line, row optical check should have which kind of distribution comes for a collection of panel, each panel, a class panel or with other The panel that suitable mode is grouped uses calibration steps.

Curve chart 470 shown in Figure 23 is similar with curve chart 450, but in figure illustrates that the skew of VREF 406 increases.Curve Figure 47 0 includes line 472 corresponding with VCOM 402 line 474 corresponding with VREF 406, and the line to drink with data 438 476.As illustrated, the time of transition in corresponding to line 476 corresponding with data 438 for the line 472 corresponding with VREF 406 Offset up at 478.VREF 406 skew leads to VCOM 402 to offset, as shown in line 472.Specifically, VREF 406 is relatively low Value when, VCOM 402 is the first value 480, and when VREF 406 rises, VCOM402 is down to second value 482.Again, it is to be noted that The stabilization time section of VCOM 402 does not change because VREF 406 offsets.

Figure 24 is shown and can be realized the various of VREF control using DAC 408 via the logical block 414 based on region The schematic diagram of input.Logical block 414 based on region can be realized using hardware, software or combination of the two.Based on area The logical block 414 in domain can based on temperature change, grid recoil distribution, picture material, pixel charge change, panel other skies Between change (for example, the change between aforementioned areas) and/or other relevant with the work of effective coverage 52 various because Usually change VREF 406.Additionally, being changing VREF 406 and spy specific region being executed in write and this region Alignment is synchronous, and the logical block 414 based on region and/or DAC 408 can receive frame start signal 432, VFB_CLK signal 440 With HSYNC signal 436.Frame start signal 432 instruction new frame has started to, and just executes write to prime area.VFB_CLK believes Numbers 440 instructions are actively writing new region.VFB_CLK signal 440 can be for being based at least partially on region in effective coverage 52 Size the predetermined quantity clock cycle (for example, the clock cycle of HSYNC signal 436).For example, in some embodiments, If effective coverage 52 is logically divided into the multiple regions being made up of 100 lines, then VFB_CLK signal 440 will be right Should be in the 100 of HSYNC signal 436 time signal.HSYNC signal 436 (or VSYNC signal) instruction is to after in region Continue (or row) write.Using these signals and parameters listed above, logical block 414 based on region and/ Or DAC 408 just can compensate change (for example, the incomplete picture in the distal region of effective coverage 52 during display 18 work Element charges) so that effective coverage 52 seems evenly.

Additionally, the VCOM tuning based on line can be used together with uniform VCOM DC distribution to a certain extent.Based on line VCOM tuning also can be applied to the high large size panel of refresh rate, and essentially without inadvertently changing using direct VCOM The stabilization time section of the VCOM that may occur in which during tuning.Also temperature change can be attached to the VCOM DC of the VCOM tuning based on line In level change.VCOM tuning based on line also can be readily applied to region specificity application, and (wherein region includes one Or many complete lines).Therefore, with refresh rate increase, based on line VCOM tuning can be additionally used in location-based not Pixel charges and compensates completely.In addition, the VCOM tuning based on content can combine so that line with the VCOM tuning based on line In (or in frame) pixel in certain content can change the VREF level being currently written into during this line at least in part, with produce Specific VCOM level.
