Example one
As shown in fig. 3.

Further, the low color cast control mode realizes a low color cast technology by creating two Gamma (Gamma) curves for the H area and the L area; after the time schedule controller obtains an initial pixel value, a first gray scale value and a second gray scale value are formed according to the initial pixel value, the pixel gray scales of the first gray scale value and the second gray scale value are different, a first loading voltage is generated according to the first gray scale value, and a second loading voltage is generated according to the second gray scale value; and the driving module obtains a first loading voltage according to the first gray scale value, obtains a second loading voltage according to the second gray scale value, and loads the first loading voltage and the second loading voltage to the pixel matrix.
Specifically, the Low color cast technology has 2 gamma curves, and the problem of viewing angle color cast is improved by matching a High (H) area with a Low (L) area; the Low gray scale brightness of the gamma curve in the High area is brighter, and the Low gray scale brightness of the gamma curve in the Low area is darker; for example, in a 4domain TFT-LCD (thin film transistor liquid crystal display), the viewing angle color shift problem can be improved by combining several HL combinations into a new pixel unit through HL combinations between adjacent sub-pixels, for example, as shown in fig. 9.
Further, the driving method is column inversion driving method.
Specifically, as shown in fig. 4, the display effect close to dot inversion can be achieved by 1-line flip + low color shift (HLLH) + column polarity inversion, and the problems of low temperature of Driver IC (driving chip) and color shift of viewing angle are solved, but the problem of longitudinal crosstalk is not well solved.
Example two
Again as shown in figure 3.
A display panel provided in this embodiment includes: the pixel matrix is formed by mutually and vertically crossing a plurality of parallel columns of data lines and a plurality of parallel rows of scanning lines to form X rows and Y columns of pixel units which are arranged in a matrix manner, wherein X and Y are positive integers; the time sequence controller is used for acquiring an initial pixel value and obtaining a gray-scale value according to the initial pixel value; the driving module is used for loading voltage to the pixel matrix according to the gray-scale value to realize display; the pixel unit comprises a plurality of sub-pixels, and the arrangement mode among the sub-pixels is a Flip pixel arrangement mode.

Furthermore, each column of sub-pixels of the pixel matrix is correspondingly connected with one data line, and each row of sub-pixels is correspondingly connected with one scanning line; the sub-pixel comprises an H (High) region and an L (Low) region; the time schedule controller presets a low color cast control mode for improving the visual angle of the panel; the driving module comprises a data driving module and a scanning driving module; the data driving module provides data signals for the corresponding sub-pixel driving circuits through the data lines, and the scanning driving module provides scanning signals for the corresponding sub-pixel driving circuits through the scanning lines.
Further, the low color cast control mode realizes a low color cast technology by creating two Gamma (Gamma) curves for the H area and the L area; after the time schedule controller obtains an initial pixel value, a first gray scale value and a second gray scale value are formed according to the initial pixel value, the pixel gray scales of the first gray scale value and the second gray scale value are different, a first loading voltage is generated according to the first gray scale value, and a second loading voltage is generated according to the second gray scale value; and the driving module obtains a first loading voltage according to the first gray scale value, obtains a second loading voltage according to the second gray scale value, and loads the first loading voltage and the second loading voltage to the pixel matrix.

Further, the driving method is an N-line (N rows of pixel signals) polarity inversion driving method.
Specifically, the present embodiment proposes that the driving architecture is a Flip pixel + N-line polarity inversion + low color shift technology architecture, which mainly addresses the problem of vertical crosstalk. As shown in fig. 5, for example, a 1-line flip + low color shift (HLLH) + 2-line polarity inversion scheme is adopted, so that the longitudinal crosstalk can be eliminated, the effect of better viewing angle is achieved, and the temperature of the Driver IC is lower as the value of N is larger; however, when the value of N is larger, the first pixel after each polarity conversion is insufficiently charged due to RC delay effect, which is more obvious under high resolution/high frequency specification, and the phenomenon appears as equidistant horizontal stripes on the panel display, for example, as shown in fig. 6 when N =8 is taken as an example.
EXAMPLE III
Again as shown in figure 3.
The display panel provided in the embodiment includes: the pixel matrix is formed by mutually and vertically crossing a plurality of parallel columns of data lines and a plurality of parallel rows of scanning lines to form X rows and Y columns of pixel units which are arranged in a matrix manner, wherein X and Y are positive integers; the time sequence controller is used for acquiring an initial pixel value and obtaining a gray-scale value according to the initial pixel value; the driving module is used for loading voltage to the pixel matrix according to the gray-scale value to realize display; the pixel unit comprises a plurality of sub-pixels, and the arrangement mode among the sub-pixels is a Flip pixel arrangement mode.
Specifically, the Flip pixel includes: 1-line flip, 2-line flip or 3-line flip; of course, the Flip pixel architecture is not limited to a 1-line Flip, and may be other Flip pixels such as a 2-line Flip and a 3-line Flip.
Furthermore, each column of sub-pixels of the pixel matrix is correspondingly connected with one data line, and each row of sub-pixels is correspondingly connected with one scanning line; the sub-pixel includes an H (High) region and an L (Low) region; the time schedule controller presets a low color cast control mode for improving the visual angle of the panel; the driving module comprises a data driving module and a scanning driving module; the data driving module provides data signals for the corresponding sub-pixel driving circuits through the data lines, and the scanning driving module provides scanning signals for the corresponding sub-pixel driving circuits through the scanning lines.
Further, the low color cast control mode realizes a low color cast technology by creating two Gamma (Gamma) curves for the H area and the L area; after the time schedule controller obtains the initial pixel value, a first gray scale value and a second gray scale value are formed according to the initial pixel value, the pixel gray scales of the first gray scale value and the pixel gray scales of the second gray scale value are different, a first loading voltage is generated according to the first gray scale value, and a second loading voltage is generated according to the second gray scale value; and the driving module obtains a first loading voltage according to the first gray scale value, obtains a second loading voltage according to the second gray scale value, and loads the first loading voltage and the second loading voltage to the pixel matrix.
Specifically, the Low color cast technology has 2 gamma curves, and the High (H) region and the Low (L) region are used in combination to improve the color cast of the viewing angle, and the specific combination is not limited to HLLH or LHHL basic cycle units; the Low gray scale brightness of the gamma curve in the High area is brighter, and the Low gray scale brightness of the gamma curve in the Low area is darker; for example, in a 4domain TFT-LCD, by using HL arrangements between adjacent sub-pixels, for example, fig. 9 shows that several HL arrangements are combined to form a new pixel unit, the color shift problem of the viewing angle can be improved by reducing the resolution.
Furthermore, the driving mode is an N-line staggered polarity inversion driving mode; the N-line staggered polarity inversion driving mode is that in a polarity inversion minimum cycle unit, the polarity inversion positions of sub-pixels of rows and columns are not in the same row and are distributed in an up-down staggered mode.
Further, the polarity inversion position refers to a position where the polarity changes in any column of sub-pixels, for example, if the 1 st sub-pixel to the a th sub-pixel of the i-th column of sub-pixels are all positive polarity, and the a +1 st sub-pixel is negative polarity, the a +1 st sub-pixel is the position where the polarity changes, where 0 is restricted to i.
Specifically, as shown in fig. 7 and 8, the panel architecture proposed in this embodiment is a Flip pixel + N-line interleaved polarity inversion + low color shift technology architecture, mainly aiming at the equidistant horizontal stripe phenomenon; the N-line interleaved polarity inversion mode comprises the following steps: the polarity inversion is performed every time the Source output (data (Line) output of a Source driver or a data driving module) outputs N lines of data, the polarity inversion positions of different Source outputs are staggered and not on a horizontal Line, the phenomenon of the existing N-Line or 1+ N-Line equidistant cross striations can be fuzzified, and when N is larger, the deformation of staggered arrangement is more: therefore, the Flip pixel driving and N-line staggered polarity inversion technology also has the effects of solving the problem of longitudinal crosstalk and scattering horizontal stripes caused by N-lines, and the like, wherein the larger the value of N is, the fewer the voltage switching times in one frame are, the lower the current of a driver IC (integrated chip of a driving circuit) is, and the lower the power consumption and the temperature are.
Example four
Again as shown in figure 3.

Further, the polarity inversion position refers to a position where the polarity changes in any column of sub-pixels, for example, if the 1 st sub-pixel to the a th sub-pixel of the i-th column of sub-pixels are all positive polarity, and the a +1 st sub-pixel is negative polarity, the a +1 st sub-pixel is the position where the polarity changes, where 0 is restricted to i.
Specifically, the N-line interleaved polarity inversion method is as follows: the polarity inversion is performed every time the Source output (data (Line) output of the Source driver or the data driving module) outputs N lines of data, the polarity inversion positions of different Source outputs are staggered and not on a horizontal Line, the phenomenon of equidistant cross striations of the current N-Line or 1+ N-Line can be fuzzified, and when N is larger, the deformation of staggered arrangement is more: therefore, the Flip pixel driving and N-line staggered polarity inversion technology also has the effects of solving the problem of longitudinal crosstalk and scattering horizontal stripes caused by N-lines, and the like, wherein the larger the value of N is, the fewer the voltage switching times in one frame are, the lower the current of a driver IC (integrated chip of a driving circuit) is, and the lower the power consumption and the temperature are.
