Description

Ways to improve horizontal crosstalk on display panels Method and device

The disclosed embodiments relate to a method for improving horizontal crosstalk of a display panel, and more particularly to a method and device for improving horizontal crosstalk of a display panel.

For a display panel using a VA (vertical alignment) panel, compared to front view, there is often a phenomenon of color washout when viewed from the side. One way to reduce color shift is to use low color shift (LCS) technology, each sub-pixel is divided into two regions, and the two regions are displayed as high gray levels respectively by separate control or capacitive coupling discharge. With low grayscale. However, when the low color shift technology is applied to the general TV size (for example, below 55 inches), if its 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 the backlight intensity needs to be increased, leading to a problem of increased cost. Another way to reduce color shift is to use digital low color shift (DLCS) technology. Use signal control to adjust the display grayscale value of the sub-pixel, for example, to make adjacent sub-pixels display high grayscale and low grayscale, respectively. It can also improve color shift and its aperture ratio can be greater than 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 substrate of the display panel is getting smaller and smaller, and the coupling effect between different signal lines is intensified, which even affects the stability of other peripheral signals. For example, when the voltage potential on the data line is undergoing polarity conversion, the voltage change caused by the polarity transition will be coupled to the common voltage (Vcom) on the common electrode to affect its voltage level. Before the thin-film transistor is charged, it is too late for the common voltage to return to the original voltage potential, which will cause the thin-film transistor to charge to the wrong voltage level, causing the display brightness to be wrong, which will cause the defect of horizontal crosstalk in the LCD panel. Because the digital low color shift technology uses a signal control method to adjust the display grayscale value of a sub-pixel, it also increases the possibility of horizontal crosstalk on its display screen, which is not conducive to improving the display quality.

FIG. 3 is a schematic diagram showing a plurality of pixels of a display panel according to an embodiment of the present disclosure displaying a pattern of the exemplary example shown in the left diagram of FIG. 2. For convenience of explanation, in this disclosure, the central area is referred to as a "target area". As shown in FIG. 3, the target area includes 8 × 8 pixels, and the target area is located in the 5th to 12th columns and the 5th to 12th rows among the plurality of pixels of the display panel. It should be noted that the size of the target area and its setting position described herein are only used to explain the embodiments of the present disclosure, but not to limit the present invention.

FIG. 4 shows the high level H or low level L of multiple sub-pixels of the display panel when the display panel according to the embodiment of the present disclosure uses the digital low color shift technology to display the pattern of the exemplary example shown in the left figure of FIG. 2. Positive polarity + or negative polarity- Arrangement diagram. It can be observed from FIG. 4 that in order to reduce color shift, adjacent sub-pixels may have different levels and / or have different polarities. It should be noted that FIG. 4 is an exemplary specific arrangement manner of the sub-pixels, and is only used to describe the embodiments of the present disclosure.

For the convenience of description, in the embodiments shown in FIGS. 3 and 4, each sub-pixel of the target area is displayed with a gray-scale value of 255, and each sub-pixel of the surrounding area outside the target area is displayed with a gray-scale value of 64. But this disclosure is not limited to this. In the embodiment of the present disclosure, it is assumed that when the sub-pixel is controlled in a signal control manner to display a 255 gray level value, the control signal voltage is 16 volts (Volt, V) under the condition of high level and positive polarity (H +). In the case of high level and negative polarity (H-), the control signal voltage is 0V. In the case of low level and positive polarity (L +), the control signal voltage is 15V. At the low level and negative polarity (L- ), The control signal voltage is 1V. Assume that when the sub-pixel is controlled by the signal control method to display 64 gray levels, the control signal voltage is 12V under the condition of high level and positive polarity (H +), and under the condition of high level and negative polarity (H-), The control signal voltage is 4V. In the case of low level and positive polarity (L +), the control signal voltage is 11V. In the case of low level and negative polarity (L-), the control signal voltage is 5V. However, this disclosure is not limited to this. Furthermore, for convenience of explanation, in the present disclosure, the above-mentioned sub-pixel control signal voltage value is referred to as the "pixel data value".

By bringing the above conditions into FIG. 4, a schematic diagram of the distribution of pixel data values of the sub-pixels of the display panel according to the embodiment of the present disclosure as shown in FIG. 5 can be obtained. In the embodiment of the present disclosure, the common electrode coupling energy will be calculated by analyzing the pixel data values in FIG. 5, which will be added below. To elaborate.

FIG. 6 is a flowchart of a method according to the present disclosure. In step S1, a plurality of common electrode coupling energies corresponding to the target area in the display panel are calculated according to the plurality of pixel data values. Please refer to FIG. 5 and FIG. 6 together. For example, for the target area, the common electrode coupling energy of the red sub-pixel in the fifth column is calculated as follows: the fourth and fifth columns and the fifth to fifth rows are calculated. In the 12th row, the sum of the difference between the pixel data values of the two red sub-pixels adjacent to each other in the column numbers, that 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 in the 6th, 7th, ..., 13th columns are then obtained, respectively, in order: -8, 8, -8, 8, -8, 8, -8, 8. For example, for the target area, the common electrode coupling energy of the green sub-pixels in the fifth column is calculated as follows: the fourth and fifth columns are connected to the fifth to twelfth rows, and the number of columns is connected. And the sum of the difference between the pixel data values of the two adjacent green sub-pixels, 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 in the 6th, 7th, ..., 13th columns are then obtained, respectively, in order: -8, 8, -8, 8, -8, 8, -8, 8. For example, for the target area, the common electrode coupling energy of the blue sub-pixels in the fifth column is calculated as follows: Calculate the number of columns in the fourth and fifth columns and the fifth to twelfth rows. The sum of the difference between the pixel data values of two blue subpixels 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, the sixth column, The common electrode coupling energies of the blue sub-pixels in the seventh column, ..., and the thirteenth column are -8, 8, -8, 8, -8, 8, -8, and 8, respectively. The arrangement list of the plurality of common electrode coupling energies corresponding to the target area in the display panel of FIG. 5 obtained above is shown in FIG. 7.

It is worth mentioning that the above-mentioned case where the coupling energy of the common electrode is not equal to zero can also be known by a similar calculation method from the configuration of the high / low level and the positive / negative polarity shown in FIG. 4. Please return to FIG. 4. For example, for the target region, the common electrode coupling energy of the red sub-pixels in the fifth column is equivalent to calculating the fourth, fifth, and fifth to twelfth rows. The sum of the difference between the high / low level and the positive / negative polarity of each two red sub-pixels with adjacent columns and adjacent positions, that is, (H +)-(L +) + (L-)-(H -) + (H +)-(L +) + (L-)-(H-) + (H +)-(L +) + (L-)-(H-) + (H +)-(L +) + (L- )-(H-) = (4H +) + (4L-)-(4L +)-(4H-) ≠ 0. From the above, it can be known that because the polarities cannot be cancelled, the common electrode coupling energy of the red sub-pixels in the fifth column is not equal to zero.

Specifically, the common electrode coupling energy is not equal to zero, which means that the common voltage (Vcom) on the common electrode is too much energy coupled by the voltage change, so that before the thin-film transistor is charged, the common voltage has no time to recover to the original voltage potential. , Which causes the display panel to have a horizontal crosstalk defect. Corresponding to this, the method proposed in this disclosure needs to try to reduce the energy of the common electrode being coupled, and even reduce it to zero, so that the horizontal crosstalk of the display panel is improved.

Please return to FIG. 6. In step S2, when there is at least one common electrode coupling energy that is not equal to zero, adjust the high / low accuracy between multiple pixels accordingly. The bit arrangement is such that the coupling energy of the at least one common electrode is all zero. For example, the high / low level arrangement between multiple pixels shown in FIG. 4 is adjusted to the high / low level arrangement as shown in FIG. 8 so that the common electrode coupling energy is reduced to zero, below More details will be given.

For example, for the target area of FIG. 8, the common electrode coupling energy of the red sub-pixels in 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 every two red sub-pixels adjacent to each other, that is, (H +)-(H +) + (L-)-(L-) + (H +)-(H +) + (L-)-(L-) + (H +)-(H +) + (L-)-(L-) + (H +)-(H +) + (L-)-( L-) = 0. It can be known from the above that, because the polarities can be canceled, the common electrode coupling energy of the red sub-pixels in the fifth column has been reduced to equal to zero.

Bringing the aforementioned high / low level, positive / negative pixel data values (control signal voltage values) into FIG. 8 can obtain the subpixels of the display panel according to the embodiment of the disclosure as shown in FIG. 9 Schematic representation of pixel data values. According to FIG. 9, a plurality of common electrode coupling energies corresponding to the target area in the display panel can be similarly calculated. The calculated list of the plurality of common electrode coupling energies corresponding to the target area in the display panel in FIG. 9 is obtained. As shown in Figure 10. It can be seen from FIG. 10 that after the high / low level arrangement between multiple pixels is adjusted, the coupling energy of multiple common electrodes corresponding to the target area in the display panel has been reduced to zero.

In detail, please refer to FIG. 4 and FIG. 8 together. For the red sub-pixels, adjust the high / low level arrangement of the red sub-pixels in the row direction. For example, in Figure 4, the red sub-pixels are on line 5 The arrangement of the high / low level from Column 1 to 16 is HLHLHLHLHLHLHLHL. In contrast, in Figure 8, the high / low level of the fifth sub-pixel is arranged from the first Columns 1 to 16 are sequentially adjusted to HLLHHLLHHLLHHLLH. For the green sub-pixels, the arrangement of the high / low levels 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 of the fifth sub-pixel in the fifth row is LHLHLHLHLHLHLHLH in order from column 1 to column 16. In contrast, in FIG. 8, the green The arrangement of the high / low level of the fifth pixel between the sub-pixels is adjusted from L1 to 16 in order to LHHLLHHLLHHLLHHL. For blue sub-pixels, adjust the arrangement of the high / low levels in the row direction between the multiple blue sub-pixels. For example, in FIG. 4, the arrangement of the high / low level of the fifth sub-pixel in the fifth row is from HLHLHLHLHLHLHLHL in order from column 1 to column 16, in contrast, in FIG. 8, The arrangement of the high / low level of the fifth sub-pixel in the fifth row is adjusted from H1 to H16 in order from H1 to H16.

Specifically, the horizontal crosstalk of the display panel is improved after adjusting the arrangement of the high / low levels between multiple pixels. It is worth mentioning that the arrangement of the high / low level between multiple pixels is not limited to the arrangement of FIG. 8. For the purposes of this disclosure, as long as the arrangement of multiple pixels of the display panel can make it correspond to the display panel The coupling energy of multiple common electrodes in the target region can be reduced to zero.
