Specific embodiment
Further detailed description is done to the present invention combined with specific embodiments below, but embodiments of the present invention are not limited to
This.
Embodiment 1:
Fig. 1 is a kind of flow diagram of display methods provided in an embodiment of the present invention, suitable for the display of picture element matrix,
The picture element matrix includes multiple sub-pixels arranged in arrays, which is characterized in that is applied to the voltage edge on the sub-pixel
Data line direction is primary every at least two scan line polarity reversions；Wherein, which comprises
Obtain compensated pixel value；
Sub-pixel present frame to be compensated first pixel value to be shown is adjusted to the second picture according to the compensated pixel value
Element value；
Within the compensation time, the second data drive signal corresponding to the second pixel value is loaded to data line, and compensating
Outside time, the first data drive signal corresponding to the first pixel value is loaded to data line.
Specifically, the pixel value size of sub-pixel is grayscale numerical value, and different gray numbers in picture element matrix display
Value corresponds to different voltage values, that is, the voltage value being loaded on sub-pixel is different, then the brightness that sub-pixel is shown is just different, ginseng
Fig. 2 is seen, for example, it is 0-255 that 8bit, which generates altogether numerical value, each grayscale is corresponding with different grayscale by taking 8bit grayscale as an example
Voltage value V0-V255, the i.e. corresponding pixel value of each grayscale, specific to the present invention, can using 10bit grayscale numerical value into
Row display, 10bit can produce 0-1023 different gray scale voltage value, compensated with facilitating to the first data drive signal, and
The obtained corresponding voltage value of the second pixel value after load compensation, the first pixel value indicate not compensate before original pixel value,
In actual operation, in addition to the pixel value of first sweep time sub-pixel, the pixel value of other sweep times is required to basis
Previous pixel value compensates, that is to say, that and the first pixel value refers to the original pixel value before not the compensating of each frame, with
The size of previous pixel value actual displayed is unrelated.In addition, specific grayscale numerical value generation is the prior art, it is no longer superfluous herein
It states, for example the grayscale numerical value such as 10bit, 12bit is generated using frame rate control (FRC, Frame Rate Control) technology.
In polarity reversion process, added polarity of voltage changes on data line pixel unit corresponding with scan line,
When the preceding pixel value of sub-pixel and current pixel value difference, storage capacitance can charge unstable in charging in pixel
Phenomenon causes storage capacitance charging insufficient, and the subsequent storage capacitance in pixel unit power supply process to, due to undertension, leading
Cause gray scale lower, and with the pixel unit in adjacent other two pixel unit of same row due to needing not move through voltage change
Process, then will not charge there is a situation where storage capacitance insufficient.Therefore, on the whole from picture element matrix, the image of display
It will appear the bright concealed wire that dark-light-dark is successively arranged.
Specifically, Fig. 3 carries out polarity reversion using the driving method of 2line inversion, to show that pure color green is
Example, at the first two sweep time (scan line 1,2 moment of scan line), signal wire 1 is responsible for green pixel, two after polarity reversion
A sweep time (scan line 3,4 moment of scan line), then overturning is is responsible for red pixel, and signal wire 2 is similarly.
Referring to drive waveforms figure shown in Fig. 4, in pure green display, synchronization can only open green pixel, and row 1 is right
The signal wire 1 answered is since the pixel of a upper sweep time is red, and before polarity reversion, signal wire 1 is not loaded with voltage,
Green pixel is corresponded to after polarity reversion, needs on-load voltage, according to the above-mentioned analysis of this implementation, causes letter in signal polarity conversion
Number distortion (distortion), and keeps luminance lower, for row 2 and row 4, since the pixel of a upper sweep time is stable,
Therefore without signal slewing distortion problem, thus luminance is higher.
The solution of the present invention can not only be applied in frame and compensate to the different subpixel of different scanning time, can also
The same sub-pixel in different frame is compensated in interframe with applying.
If applied in frame, generally, due to the factor of polarity reversion, so that being loaded into the data-signal on data line
The corresponding voltage of preset first pixel value cannot be quickly reached after the reversion of each polarity, fills charging capacitor charging not
Point, leading to after discharge spread of voltage, gray scale is lower than original display gray scale, it be easy to cause distortion, and next sub-pixel
The voltage of upper load is due to being the voltage in stable state, and sufficiently, discharge voltage is stablized for charging, and gray scale is more steady
It is fixed, therefore exist not go together and show gray difference, horizontal bright concealed wire phenomenon is derived, picture quality is reduced.Therefore, the present invention is logical
Cross the voltage swing for being loaded into sub-pixel for comparing adjacent sweep time, corresponding compensation current sub-pixel institute making alive, Neng Gourang
The quick charge within the first segment sweep time after polarity reversion of the storage capacitance of sub-pixel to be compensated is complete, makes picture element matrix
Each storage capacitance it is subsequent can stable discharging to overcome horizontal bright concealed wire phenomenon improve image quality.
Embodiment 2:
In one specific embodiment of the present embodiment, the acquisition compensated pixel value includes:
The preceding pixel value that is shown according to the preceding sub-pixel of the sub-pixel to be compensated and sub-pixel to be compensated show first
Pixel value obtains the compensated pixel value；The compensated pixel value compensation method specifically:
As P=C, VP,C=Vmin；
As P=Pmax and C=Cmin, VP,C=Vmax；
As P=Pmin and C=Cmax, VP,C=Vmax；
As C > P, so that Vmin≤VP,C≤VP-1,C≤Vmax；Vmin≤VP,C-1≤VP,C≤Vmax；
As C < P, so that Vmax >=VP,C≥VP-1,C≥Vmin；Vmax≥VP,C-1≥VP,C≥Vmin；
Wherein, P indicates preceding pixel value, and C indicates the first pixel value, VP,CExpression preceding pixel value size is P, the first pixel value

In frame, the pixel value of block of pixels to be loaded is called current pixel value, a upper block of pixels for the block of pixels respective column
The pixel value of upper load is known as preceding pixel value, and from the time, in a frame, last moment loads in a upper block of pixels
Corresponding preceding pixel value, current time will load corresponding current pixel value in block of pixels to be loaded.That is current pixel value
Corresponding sub-pixel to be compensated, preceding pixel value correspond to a upper pixel for sub-pixel block respective column to be compensated.With first in this example
Pixel value be 8bit grayscale numerical value for, after compensation due to the size of the second pixel value may be greater than 255, use
10bit is exported.
In table 1, it is exactly the numerical value on diagonal line that C=P, which is reflected in the offset in table, that is, if preceding pixel value and current
Pixel value is equal, indicates that front and back display grayscale is constant, therefore do not need to compensate, such as in Fig. 4, signal wire 2 is loaded into
The voltage of row 3 and the voltage for being loaded into row 4 are V+255, then do not need to compensate row 4；C > P is reflected in the compensation in table
Value is exactly cornerwise lower half of triangle, that is, when current pixel value is greater than preceding pixel value, indicates that current gray is greater than preceding ash
Rank may cause charging if uncompensation and sufficiently generate bright concealed wire due to producing grey scale, in specific compensation,
In the case where current pixel value is certain, preceding pixel value is bigger, shows that the two is closer, offset successively decreases until being 0, in preceding picture
In the case that element value is certain, current pixel value is smaller, and when compensation successively decreases until being 0, in a pole, as P=Pmax=255 and
When C=Cmin=1, VP,C=Vmax=15；Benefit since 1 offset of table is symmetrical about the diagonal line of C=P, in the case where C < P
Repay value with the offset in the case where C > P be it is corresponding, in a pole, as P=Pmin=1 and C=Cmax=255,
VP,C=Vmax=15, such as in Fig. 4, the voltage value that signal wire 2 is loaded into row 2 is 0, the voltage for being loaded into row 3 is V+255,
