Detailed Description
In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
The most key concept of the invention is as follows: if two adjacent and same pixel unit signals exist in the acquired pixel unit signals, the charging time of all the pixel unit signals in the pixel period is adjusted, and the consistency of the pixel unit signal charging effect in the double-gate panel is realized.
Referring to fig. 1, the technical solution provided by the present invention is:
a driving method of a dual gate panel includes the steps of:
s1, acquiring pixel unit signals to be charged mounted on the same source electrode line in one pixel period in the double-gate panel;
s2, judging whether two adjacent and same pixel unit signals exist in the acquired pixel unit signals;
and S3, if yes, adjusting the charging time of all pixel unit signals in the pixel period.
From the above description, the beneficial effects of the present invention are:
according to the driving method of the double-gate panel, the pixel unit signals to be charged mounted on the same source electrode line are judged, if two adjacent and same pixel unit signals exist in the obtained pixel unit signals, the charging time of all the pixel unit signals in a pixel period is adjusted, the charging time difference between the pixel unit signals caused by the arrangement of the double-gate pixel units is made up by dynamically adjusting the charging time of the adjacent pixel unit signals, the consistency of the charging effect of the pixel unit signals in the double-gate panel is realized, the grid problem of the double-gate panel technology is improved, and the display quality of the double-gate panel is improved.
Further, step S3 is specifically:
if so, shortening the rising edge charging time of a pixel unit signal to be charged later in two adjacent and same pixel unit signals to be charged mounted on the same source line, and prolonging the falling edge charging time of a pixel unit signal to be charged earlier in two adjacent pixel unit signals to be charged mounted on the same source line as the charging mode of the two adjacent and same pixel unit signals; the shortened rising edge charge time is equal to the extended falling edge charge time; the charging time of each pixel unit signal to be charged comprises a rising edge and a falling edge which are sequentially continuous;
and respectively charging the pixel unit signals to be charged which are mounted on the same source electrode line in a charging mode of the two adjacent and same pixel unit signals.
As can be seen from the above description, if two adjacent and identical pixel unit signals exist in the obtained pixel unit signals, since the previous pixel unit signal in the two adjacent and identical pixel unit signals precharges the next pixel unit signal, and the charging time of the next pixel unit signal is longer than that of the previous pixel unit signal, the charging time of the pixel unit signal to be charged hanging on the same source line is balanced by shortening the charging time of the rising edge of the next pixel unit signal to be charged and prolonging the charging time of the falling edge of the previous pixel unit signal to be charged, so that the charging effects of the pixel unit signals in the dual-gate panel are consistent, and the display quality of the dual-gate panel is improved.
Further, step S3 is specifically:
if so, shortening the rising edge charging time of a previous pixel unit signal to be charged in two adjacent and same pixel unit signals to be charged mounted on the same source line, and prolonging the falling edge charging time of a next pixel unit signal to be charged in two adjacent pixel unit signals to be charged mounted on the same source line, wherein the falling edge charging time is used as the charging mode of the two adjacent and same pixel unit signals; the shortened rising edge charge time is equal to the extended falling edge charge time; the charging time of each pixel unit signal to be charged comprises a rising edge and a falling edge which are sequentially continuous; the total charging time after the extended falling edge charging time of one pixel unit signal to be charged is equal to the charging saturation time of the pixel unit signal to be charged;
and respectively charging the pixel unit signals to be charged which are mounted on the same source electrode line in a charging mode of the two adjacent and same pixel unit signals.
It can be known from the above description that the grid defect phenomenon of the dual-gate panel is mainly caused by the charging difference between two adjacent and same pixel unit signals, the charging effect of other pixel unit signals in the same column of pixel unit signals is far worse than that of the pixel unit signals to be precharged (as long as there are two adjacent and same pixel unit signals in the pixel unit signals mounted on the same source line in the dual-gate panel, the previous pixel unit signal in the two adjacent and same pixel unit signals precharges the next pixel unit signal), so the charging time of the pixel unit signals to be charged mounted on the same source line is balanced by shortening the charging time of the rising edge of the previous pixel unit signal to be charged and prolonging the charging time of the falling edge of the next pixel unit signal to be charged, the charging time of the pixel unit signals in the same column is prolonged to the saturation charging time of the pixel unit signals to be charged, so that the pixel unit signals which are precharged do not appear too bright, the charging effect of the pixel unit signals in the double-gate panel is consistent, and the display quality of the double-gate panel is improved.
Further, step S3 further includes the following steps:
adjusting the charging start time on the gate lines correspondingly connected with the pixel unit signals with the shortened charging time on the same source line respectively, and advancing the charging start time by a first time length which is equal to the shortened charging time on the rising edge; and each pixel unit signal to be charged mounted on the same source line is correspondingly connected with one gate line.
As can be seen from the above description, the charging start time of the pixel unit signal mounted on the same source line and having the shortened charging time of the rising edge is adjusted on the gate line correspondingly connected to the pixel unit signal, so that the charging effect of the pixel unit signal connected on each gate line is consistent, and the phenomenon of mis-charging of the source line is avoided.
Referring to fig. 1, a first embodiment of the present invention is:
a driving method of a dual gate panel includes the steps of:
s1, acquiring pixel unit signals to be charged mounted on the same source electrode line in one pixel period in the double-gate panel;
s2, judging whether two adjacent and same pixel unit signals exist in the acquired pixel unit signals;
and S3, if yes, adjusting the charging time of all pixel unit signals in the pixel period.
The specific adjustment method for the charging time of all pixel unit signals in the pixel period has the following two cases:
the first condition is as follows:
step S3 specifically includes:
if so, shortening the rising edge charging time of a pixel unit signal to be charged later in two adjacent and same pixel unit signals to be charged mounted on the same source line, and prolonging the falling edge charging time of a pixel unit signal to be charged earlier in two adjacent pixel unit signals to be charged mounted on the same source line as the charging mode of the two adjacent and same pixel unit signals; the shortened rising edge charge time is equal to the extended falling edge charge time; the charging time of each pixel unit signal to be charged comprises a rising edge and a falling edge which are sequentially continuous; the total charging time after the extended falling edge charging time of one pixel unit signal to be charged is equal to the charging saturation time of the pixel unit signal to be charged;
and respectively charging the pixel unit signals to be charged which are mounted on the same source electrode line in a charging mode of the two adjacent and same pixel unit signals.
Case two:
step S3 specifically includes:
if so, shortening the rising edge charging time of a previous pixel unit signal to be charged in two adjacent and same pixel unit signals to be charged mounted on the same source line, and prolonging the falling edge charging time of a next pixel unit signal to be charged in two adjacent pixel unit signals to be charged mounted on the same source line, wherein the falling edge charging time is used as the charging mode of the two adjacent and same pixel unit signals; the shortened rising edge charge time is equal to the extended falling edge charge time; the charging time of each pixel unit signal to be charged comprises a rising edge and a falling edge which are sequentially continuous;
and respectively charging the pixel unit signals to be charged which are mounted on the same source electrode line in a charging mode of the two adjacent and same pixel unit signals.
Step S3 further includes the steps of:
adjusting the charging start time on the gate lines correspondingly connected with the pixel unit signals with the shortened charging time on the same source line respectively, and advancing the charging start time by a first time length which is equal to the shortened charging time on the rising edge; and each pixel unit signal to be charged mounted on the same source line is correspondingly connected with one gate line.
The specific embodiment of the scheme is as follows:
referring to fig. 2, a pixel unit signal arrangement of a dual gate panel is shown, in which every three source lines are one period, for example: s2, S3 and S4 are one period, S5, S6 and S7 are one period, and so on.
Taking the pixel cell signal mounted in S5 as an example, the following are sequentially performed from top to bottom (the color of the pixel cell signal): blue → red → green → blue → red → green → blue … … → green → blue; blue → red → green → blue is a period, at this time, the color of the last pixel cell signal in the previous period of two adjacent periods is blue (called as the first blue pixel cell signal), and the color of the first pixel cell signal in the next period of two adjacent periods is also blue (called as the second blue pixel cell signal), so that the second blue pixel cell signal is pre-charged by the first blue pixel cell signal, and under the condition of equal voltage, the brightness of the pixel cell signals is inconsistent, and the grid-shaped defect phenomenon can occur in the dual-gate panel.
The pixel cell signals mounted in S6 are, in order from top to bottom (the colors of the pixel cell signals): green → blue → green → red → green → blue → green → red … … → green → red; green → blue → green → red is a period, and the pixel cell signals mounted in S7 are, from top to bottom (the colors of the pixel cell signals): green → red → blue → red → green → red → blue → red. . . Green → red → blue → red is a period, and it can be seen that the pixel cell signals mounted on the source lines S6 and S7 are not S5, so there is no problem of precharging.
The charging time of the pixel unit signal mounted in S5 is adjusted in the following two ways:
the first method is as follows:
the pixel cell signals mounted in S5 are, in order from top to bottom (the colors of the pixel cell signals): blue → red → green → blue … … → green → blue, respectively: a first pixel cell signal (blue), a second pixel cell signal (red), a third pixel cell signal (green), a fourth pixel cell signal (blue), and a fifth pixel cell signal (blue);
the charging time of each pixel unit signal mounted on the original source line S5 is the same (see S5 and STB signal line in fig. 3, five pixel unit signals on the S5 signal line correspond to the charging time of the rising edge and the falling edge on the STB signal line one by one, each pixel unit signal corresponds to the charging time of a rising edge and a falling edge, 1H represents the charging time of the pixel unit signal before adjustment, by dynamically adjusting the charging time of each rising edge and falling edge on the STB signal line, the charging time of the rising edge corresponding to the first pixel unit signal, the third pixel unit signal and the fifth pixel unit signal is all decreased (t represents the decreased charging time), the charging time of the falling edge corresponding to the second pixel unit signal and the fourth pixel unit signal is all increased (the increased charging time is the same as the decreased charging time, all indicated by t), the total charging time of the first pixel unit signal, the third pixel unit signal and the fifth pixel unit signal becomes 1H-t (1H before adjustment), the total charging time of the second pixel unit signal and the fourth pixel unit signal becomes 1H + t (1H before adjustment), so that the fourth pixel unit signal without pre-charging obtains more charging time, the charging time of the fifth pixel unit signal decreases, the brightness of two adjacent and same pixel unit signals is consistent, and the charging time after adjustment refers to the STB' signal line (1H-t, 1H + t, 1H-t, 1H + t and 1H-t in sequence) in fig. 3.
Referring to fig. 2, a first pixel unit signal mounted on a source line is connected to a first gate line (indicated by G1 in fig. 2), a second pixel unit signal is connected to a second gate line (indicated by G2 in fig. 2), a third pixel unit signal is connected to a third gate line (indicated by G3 in fig. 2), a fourth pixel unit signal is connected to a fourth gate line (indicated by G4 in fig. 2), and a fifth pixel unit signal is connected to a fifth gate line (indicated by G5 in fig. 2), because the charging time of the first pixel unit signal (corresponding to G1), the third pixel unit signal (corresponding to G3) and the fifth pixel unit signal (corresponding to G5) is reduced, the charging time of the pixel unit signals connected to G1, G2, G3, G4 and G5 is kept the same, and the charging start time of the G1, G3 and G5 signal lines is advanced by t;
after the charging time on the STB signal line and the Gate (i.e., G1-G5) signal line is adjusted, since the pixel cell signals mounted on S6 and S7 are also connected to the corresponding Gate lines, the charging time of the pixel cell signals mounted on S6 and S7 is correspondingly changed, as follows:
referring to fig. 4, the pixel cell signals mounted in S6 are, from top to bottom (the colors of the pixel cell signals): green → blue → green → red → green … … → green → red, respectively: a1 (green), b1 (blue), c1 (green), d1 (red) and e1 (green), the charging time of each pixel cell signal is 1H-t, 1H + t, 1H-t, 1H + t and 1H-t (corresponding to five pixel cell signals of a1, b1, c1, d1 and e1, respectively, see STB' signal line in fig. 4).
Referring to fig. 5, the pixel cell signals mounted in S7 are, from top to bottom (the colors of the pixel cell signals): green → red → blue → red → green … … → blue → red, respectively: a2 (green), b2 (red), c2 (blue), d2 (red) and e2 (green), the charging time of each pixel cell signal is 1H-t, 1H + t, 1H-t, 1H + t and 1H-t (corresponding to five pixel cell signals of a2, b2, c2, d2 and e2, respectively, see STB' signal line in fig. 5).
The second method comprises the following steps:
the grid defect of the dual-gate panel is mainly caused by the charging difference of two adjacent and same pixel cell signals, the pixel cell signals of column B2 in fig. 2 are all pixel cell signals of the same color, which can be respectively represented by B21, B22, B23 and B24, and since B23 is precharged, the charging effect of the pixel cell signals of B21, B22 and B24 is worse than that of the pixel cell signals of B23, so that the charging is performed by the following charging method:
referring to fig. 6, the charging time of each pixel cell signal mounted on the original source line S5 is the same (see S5 and STB signal line in fig. 6, five pixel cell signals on S5 signal line correspond to the charging time of the rising edge and the falling edge on STB signal line one by one, each pixel cell signal corresponds to the charging time of a rising edge and the charging time of a falling edge, denoted by 1H, the charging time of the pixel cell signal before adjustment, by dynamically adjusting the charging time of each rising edge and falling edge on STB signal line, the charging time of the rising edge corresponding to the second pixel cell signal and the fourth pixel cell signal is decreased (denoted by p, the decreased charging time), the charging time of the falling edge corresponding to the first pixel cell signal, the third pixel cell signal and the fifth pixel cell signal is increased (the increased charging time is the same as the decreased charging time, all denoted by p), the total charging time of the first pixel unit signal, the third pixel unit signal and the fifth pixel unit signal becomes 1H + p (1H before adjustment), the total charging time of the second pixel unit signal and the fourth pixel unit signal becomes 1H-p (1H before adjustment), 1H + p is equal to the charging saturation time of the pixel unit signals, and the adjusted charging time refers to the STB' signal line (1H + p, 1H-p, 1H + p, 1H-p and 1H + p in order) in fig. 6.
Since each pixel unit signal mounted on the source line is correspondingly connected to one gate line, the charging time of the pixel unit signals of column B2 can reach the charging saturation time of the pixel unit signals after the adjustment in the second way.
In the same manner as described above, in order to keep the charging time periods of the pixel cell signals connected to G1, G2, G3, G4, and G5 uniform, the start charging time periods on the G2 and G4 signal lines are advanced by p.
Similarly, after the charging time on the STB signal line and the Gate (i.e., G1-G5) signal line is adjusted, the charging time of the pixel signals mounted on S6 and S7 changes accordingly because the pixel signals mounted on S6 and S7 are also connected to the corresponding Gate lines, as follows:
referring to fig. 7, the pixel cell signals mounted in S6 are, from top to bottom (the colors of the pixel cell signals): green → blue → green → red → green … … → green → red, respectively: a1 (green), b1 (blue), c1 (green), d1 (red) and e1 (green), the charging time of each pixel cell signal is 1H + p, 1H-p, 1H + p, 1H-p and 1H + p (corresponding to five pixel cell signals of a1, b1, c1, d1 and e1, respectively, see STB' signal line in fig. 7).
Referring to fig. 8, the pixel cell signals mounted in S7 are, from top to bottom (the colors of the pixel cell signals): green → red → blue → red → green … … → blue → red, respectively: a2 (green), b2 (red), c2 (blue), d2 (red) and e2 (green), the charging time of each pixel cell signal is 1H + p, 1H-p, 1H + p, 1H-p and 1H + p (corresponding to five pixel cell signals of a2, b2, c2, d2 and e2, respectively, see STB' signal line in fig. 8).
The charging saturation time can be defined by measuring the brightness of a specific frame (for example, a frame with one line being on and one line being off, specifically related to the pixel arrangement), and when the charging time is increased to a certain value and the brightness is not changed, the charging saturation time is obtained.
In summary, the driving method of the dual-gate panel provided by the present invention judges the acquired pixel unit signals to be charged mounted on the same source line, if two adjacent and same pixel unit signals exist in the acquired pixel unit signals, the charging time of all pixel unit signals in the pixel period is adjusted, and the charging time of the adjacent pixel unit signals is dynamically adjusted to compensate for the difference in charging time between the pixel unit signals caused by the arrangement of the dual-gate pixel units, so as to achieve the consistency of the charging effect of the pixel unit signals in the dual-gate panel, thereby improving the grid problem of the dual-gate panel technology and further improving the display quality of the dual-gate panel.
