Description

The side to improve the horizontal crosstalk of the display panel Method and device

The present disclosure relates to a method for improving horizontal crosstalk of a display panel, and more particularly to a method and apparatus for improving horizontal crosstalk of a display panel.

For a display panel using a VA (vertical alignment) panel, there is often a color washout phenomenon when viewed from the side as compared with the front view. One way to reduce the color shift is to use low color shift (LCS) technology to divide each sub-pixel into two regions and display the two regions as high gray scales separately or in a capacitively coupled discharge manner. With low gray levels. However, when the low color shift technique is applied to a general TV size (for example, 55 吋 or less), if the resolution is as large as ultra-high definition (UHD) (that is, the resolution is 3840×2160), there will be The aperture ratio is insufficient and it is necessary to increase the backlight intensity, resulting in an increase in cost. Another way to reduce color shift is to use digital low color shift (DLCS) technology. The display gray scale value of the sub-pixel is adjusted by signal control, for example, the adjacent sub-pixels are respectively displayed as high gray scale and low gray scale, which can also improve the color shift and the aperture ratio can be greater than the traditional low color shift technology. .

On the other hand, with the reduction of the pixel size, the line spacing of the thin film transistors on the display panel is getting smaller and smaller, and the coupling between the different signal lines is intensified, which even affects the stability of other signals around. For example, when the voltage potential on the data line is doing the polarity conversion, the voltage change caused by the polarity transition is coupled to the common voltage (Vcom) on the common electrode to affect its voltage level. Before the end of the charging of the thin film transistor, the common voltage cannot be restored to the original voltage potential, and the thin film transistor is charged to the wrong voltage level, causing the brightness of the display to be wrong, thereby causing the horizontal crosstalk of the liquid crystal display panel. Since the digital low color shifting technology adjusts the display gray scale value of the sub-pixel by the signal control method, the possibility of horizontal crosstalk of the display screen is increased, which is not conducive to improving the display quality.

The above conditions are brought into FIG. 4 to obtain a schematic diagram of the allocation of the pixel data values of the sub-pixels of the display panel according to the embodiment of the present disclosure as shown in FIG. 5. In the embodiment of the present disclosure, the common electrode coupling energy is simulated by analyzing the pixel data values in FIG. 5, and the following will be added. To detail.

6 is a flow chart of a method in accordance with the present disclosure. In step S1, a plurality of common electrode coupling energies corresponding to the target regions in the display panel are calculated according to the plurality of pixel data values. Referring to FIG. 5 and FIG. 6 together, for example, for the target area, the common electrode coupling energy of the red sub-pixels of the fifth column is calculated by calculating the fourth column and the fifth column and the fifth row to In the 12th row, the sum of the difference values of the pixel data values of each of the two red sub-pixels whose number of columns is adjacent and adjacent to each other is (16-11)+(1-4)+(16-11 ) + (1-4) + (16-11) + (1-4) + (16-11) + (1-4) = 8. In this way, the common electrode coupling energies of the red sub-pixels of the sixth column, the seventh column, the ..., and the thirteenth column are respectively obtained, which are sequentially -8, 8, -8, 8, -8, 8, respectively. -8, 8. For example, for the target region, the common electrode coupling energy of the green sub-pixel of the fifth column is calculated by calculating the number of columns in the fourth column and the fifth column and the fifth row to the twelfth row. And the sum of the difference values of the pixel data values of every two green sub-pixels adjacent to each other, that is, (1-4) + (16-11) + (1-4) + (16-11) + (1 -4) + (16-11) + (1-4) + (16-11) = 8. In this way, the common electrode coupling energies of the green sub-pixels of the sixth column, the seventh column, the ..., and the thirteenth column are respectively obtained, and are sequentially -8, 8, -8, 8, -8, 8, respectively. -8, 8. For example, for the target region, the common electrode coupling energy of the blue sub-pixels of the fifth column is calculated by calculating the number of columns in the fourth and fifth columns and the fifth to twelfth rows. The sum of the differences of the pixel data values of each of the two blue sub-pixels adjacent to each other, that is, (16-11)+(1-4)+(16-11)+(1-4)+ (16-11) + (1-4) + (16-11) + (1-4) = 8. In this way, then find the sixth column, The common electrode coupling energy of the blue sub-pixels of the seventh column, ..., and the thirteenth column is -8, 8, -8, 8, -8, 8, -8, and 8, respectively. The plurality of common electrode coupling energy sorting lists obtained in the above with respect to the target area in FIG. 5 corresponding to the display panel are as shown in FIG.

It is worth mentioning that the above-mentioned case where the common electrode coupling energy is not equal to zero can also be known from the configuration of the high/low level and the positive/negative polarity shown in FIG. 4 in a similar calculation manner. Please return to FIG. 4, for example, for the target region, the common electrode coupling energy of the red sub-pixels of the fifth column is equivalent to: calculating the fourth column and the fifth column and the fifth row to the twelfth row, The sum of the difference between the high/low level and the positive/negative polarity of each of the two red sub-pixels whose number of columns is adjacent and adjacent to each other, that is, (H+)-(L+)+(L-)-(H -)+(H+)-(L+)+(L-)-(H-)+(H+)-(L+)+(L-)-(H-)+(H+)-(L+)+(L- )-(H-)=(4H+)+(4L-)-(4L+)-(4H-)≠0. As can be seen from the above, since the polarities cannot be canceled, the common electrode coupling energy of the red sub-pixels of the fifth column is not equal to zero.

Specifically, the common electrode coupling energy is not equal to zero, and the common voltage (Vcom) on the common electrode is excessively coupled by the voltage change, so that the common voltage cannot be restored to the original voltage potential before the end of the charging of the thin film transistor. , resulting in a horizontal crosstalk defect in the display panel. Corresponding to this, the method proposed by the present disclosure requires that the energy of the common electrode being coupled be reduced, even to zero, so that the horizontal crosstalk of the display panel is improved.

Returning to FIG. 6, in step S2, when there is at least one common electrode coupling energy not equal to zero, the high/low level between the plurality of pixels is adjusted accordingly. The bit arrangement is such that the at least one common electrode coupling energy is equal to zero. For example, the high/low level arrangement between the plurality of pixels shown in FIG. 4 is adjusted to a high/low level arrangement as shown in FIG. 8, so that the common electrode coupling energy is reduced to be equal to zero, Will be detailed again.

For example, for the target region of FIG. 8, the common electrode coupling energy of the red sub-pixels of the fifth column is equivalent to: calculating the number of columns in the fourth and fifth columns and the fifth to twelfth rows. The sum of the difference between the high/low level and the positive/negative polarity of each of the two red sub-pixels adjacent to the position, that is, (H+)-(H+)+(L-)-(L-)+ (H+)-(H+)+(L-)-(L-)+(H+)-(H+)+(L-)-(L-)+(H+)-(H+)+(L-)-( L-) = 0. As can be seen from the above, since the polarities can be cancelled, the common electrode coupling energy of the red sub-pixels of the fifth column has been reduced to be equal to zero.

Taking the aforementioned high/low level, positive/negative polarity pixel data values (control signal voltage values) into FIG. 8 can obtain the sub-pixels of the display panel according to the embodiment of the present disclosure as shown in FIG. Schematic diagram of the allocation of pixel data values. According to FIG. 9, a plurality of common electrode coupling energies corresponding to the target regions in the display panel can be similarly calculated, and the plurality of common electrode coupling energy collation lists corresponding to the target regions in the display panel of FIG. 9 are obtained. As shown in Figure 10. As can be seen from FIG. 10, after adjusting by the high/low level alignment between the plurality of pixels, the plurality of common electrode coupling energies corresponding to the target regions in the display panel have been reduced to be equal to zero.

In detail, please refer to FIG. 4 and FIG. 8 together to adjust the arrangement of the high/low level in the row direction between the plurality of red sub-pixels for the red sub-pixel. For example, in Figure 4, the red subpixel is between line 5 The high/low level arrangement is from HLHLHLHLHLHLHLHL in order from column 1 to column 16, in contrast, in Figure 8, the arrangement of high/low levels in row 5 between red sub-pixels is from Columns 1 through 16 are sequentially adjusted to HLLHHLLHHLLHHLLH. For the green sub-pixel, the high/low level arrangement in the row direction between the plurality of green sub-pixels is adjusted. For example, in FIG. 4, the arrangement of the high/low levels in the fifth row between the green sub-pixels is sequentially from the first column to the 16th column as LHLHLHLHLHLHLHLH, in contrast, in FIG. The arrangement of the high/low levels in the fifth row between the sub-pixels is sequentially adjusted from the first column to the 16th column to LHHLLHHLLHHLLHHL. For the blue sub-pixel, the high/low level arrangement in the row direction between the plurality of blue sub-pixels is adjusted. For example, in FIG. 4, the arrangement of the high/low levels in the fifth row between the blue sub-pixels is sequentially HLHLHLHLHLHLHLHL from the first column to the 16th column, in FIG. 8, in FIG. The arrangement of the high/low levels in the fifth row between the blue sub-pixels is sequentially adjusted from the first column to the 16th column to HLLHHLLHHLLHHLLH.

Specifically, the horizontal crosstalk of the display panel is improved after being adjusted by the high/low level alignment between the plurality of pixels. It is to be noted that the arrangement of the high/low level between the plurality of pixels is not limited to the arrangement of FIG. 8. For the disclosure, as long as the pixels of the display panel are arranged in a manner corresponding to the display panel The plurality of common electrode coupling energies of the target region are reduced to be equal to zero.
