[0025] In order to more clearly illustrate the present invention, the present invention will be further described below in conjunction with the embodiments and drawings. Similar components in the drawings are represented by the same reference numerals. It should be understood by those skilled in the art that the following specific description is illustrative rather than restrictive and should not be used to limit the scope of protection of the present invention.
[0026] In the process of implementing the present invention, the inventors discovered that the prior art has at least the following problems:
[0027] TFT LCD panels require positive and negative voltage driving due to the characteristics of liquid crystal. Common liquid crystal driving inversion methods include Frame Inversion, Row Inversion, Column Inversion, and Dot Inversion. Figure 1 As shown in Table 1, the commonly used inversion methods are column inversion and dot inversion.
[0028] Table 1
[0029]
[0030] The column inversion method has the advantage of low power consumption, but its quality performance such as low flicker and low crosstalk is poor. Due to the feed-through effect of TFT, the optimal VCOM (LCD common voltage) is different at different positions of the displayed image. The dot inversion method disperses the voltage asymmetry to various positions of the TFT LCD liquid crystal panel, offsetting the voltage asymmetry to the greatest extent and making the optimal VCOM as uniform as possible. Therefore, the dot inversion method has good quality performance such as low flicker and low crosstalk, but it has the highest power consumption.
[0031] Taking the automotive TFT LCD panel as an example, currently, most automotive TFT LCD panels use the Dual gate + (1 + 2 Dot Inversion) inversion method.

The 10th gate line Gate10 is connected to the sub-pixels in the odd columns of the 5th row, the 11th gate line Gate11 is connected to the sub-pixels in the odd columns of the 6th row, the 12th gate line Gate12 is connected to the sub-pixels in the even columns of the 6th row, the 1st data line Source1 is connected to the sub-pixels in the 1st and 2nd columns, the 2nd data line Source2 is connected to the sub-pixels in the 3rd and 4th columns, the 3rd data line Source3 is connected to the sub-pixels in the 5th and 6th columns, and the 4th data line Source4 is connected to the sub-pixels in the 7th and 8th columns.

[0032] One sub-pixel is connected to one data line and one gate line. Two gate lines are set between two adjacent rows of sub-pixels. One gate line is set on the side of the first and last rows of sub-pixels without adjacent sub-pixels. In combination with 1+2 Dot Inversion, the voltage polarity is switched once after each pair of two sub-pixels on the data line is charged, which is +5V to -5V or -5V to +5V (except Figure 2 In the embodiment, the fixed amplitude of 5 is used as an example just for the convenience of explanation, because the embodiment mainly focuses on the number of switching times. Figure 3 As shown, the specific driving method of the existing array substrate using the Dual gate + (1 + 2 Dot Inversion) inversion method is:
[0033] In the current frame period, the 12 gate lines are scanned row by row, wherein when scanning the first gate line Gate1, the sub-pixels in the first row, the first column, and the fifth column are charged with a +5V data signal through the first and third data lines Source1 and Source3, respectively, and the sub-pixels in the first row, the third column, and the seventh column are charged with a -5V data signal through the second and fourth data lines Source2 and Source4, respectively.

[0038] When scanning the 6th gate line Gate6, the sub-pixels in the 3rd row, 2nd column and 6th column are charged with -5V data signals through the 1st and 3rd data lines Source1 and Source3 respectively, and the sub-pixels in the 3rd row, 4th column and 8th column are charged with +5V data signals through the 2nd and 4th data lines Source2 and Source4 respectively.
[0039] When scanning the 7th gate line Gate7, the 1st and 5th sub-pixels in the 4th row are charged with -5V data signals through the 1st and 3rd data lines Source1 and Source3 respectively, and the 3rd and 7th sub-pixels in the 4th row are charged with +5V data signals through the 2nd and 4th data lines Source2 and Source4 respectively.
[0040] When scanning the 8th gate line Gate8, the 2nd and 6th sub-pixels in the 4th row are charged with +5V data signals through the 1st and 3rd data lines Source1 and Source3 respectively, and the 4th sub-pixels in the 4th row are charged with -5V data signals through the 2nd and 4th data lines Source2 and Source4 respectively.
[0041] When scanning the 9th gate line Gate9, the 1st and 5th column sub-pixels in the 5th row are charged with +5V data signals through the 1st and 3rd data lines Source1 and Source3 respectively, and the 3rd and 7th column sub-pixels in the 5th row are charged with -5V data signals through the 2nd and 4th data lines Source2 and Source4 respectively.
[0042] When scanning the 10th gate line Gate10, the sub-pixels in the 5th row, 2nd column and 6th column are charged with -5V data signals through the 1st and 3rd data lines Source1 and Source3 respectively, and the sub-pixels in the 5th row, 4th column and 8th column are charged with +5V data signals through the 2nd and 4th data lines Source2 and Source4 respectively.
[0043] When scanning the 11th gate line Gate11, the sub-pixels in the 1st and 5th columns of the 6th row are charged with -5V data signals through the 1st and 3rd data lines Source1 and Source3 respectively, and the sub-pixels in the 3rd and 7th columns of the 6th row are charged with +5V data signals through the 2nd and 4th data lines Source2 and Source4 respectively.
[0044] When scanning the 12th gate line Gate12, the sub-pixels in the 6th row, 2nd column and 6th column are charged with +5V data signals through the 1st and 3rd data lines Source1 and Source3 respectively, and the sub-pixels in the 6th row, 4th column and 8th column are charged with -5V data signals through the 2nd and 4th data lines Source2 and Source4 respectively.
[0045] In the next frame period, the 12 gate lines are scanned row by row, and the driving method is the same as that of the current frame period mentioned above, except that the +5V data signal of the current frame period is converted into a -5V data signal, and the -5V data signal of the current frame period is converted into a +5V data signal, which will not be repeated here.
[0046] The power consumption of automotive TFT LCD panels is positively correlated with the number of voltage switching times and the switching amplitude on the data line. That is, the more times the voltage on the data line switches, the greater the power consumption; the greater the amplitude of the voltage switching on the data line, the greater the power consumption. For example, the power consumption of switching from +5V to -5V (absolute voltage value 10V) is greater than that of switching from +5V to 0V (absolute voltage value 5V). Therefore, according to the specific driving method of the array substrate of the above-mentioned Dual gate+(1+2DotInversion) inversion method, it can be known that when the 1+2DotInversion inversion method is applied, the voltage polarity of the data line is switched once after each pair of two sub-pixels are charged. Taking the first data line Source1 as an example, when scanning the second gate line Gate2 and the third gate line Gate3, the first data line Source1 provides a -5V data signal. When scanning the fourth gate line Gate4 and the fifth gate line Gate5, the first data line Source1 switches to provide a +5V data signal. When scanning the sixth gate line Gate6 and the seventh gate line Gate7, the first data line Source1 switches back to providing a -5V data signal, and so on. The power consumption is very high. In addition, under the Dual gate+(1+2DotInversion) inversion method, the sub-pixels are still switched alternately in two columns / two columns, that is, the quality performance such as low flicker and low crosstalk is still not as good as that of the conventional method. Figure 1 The true point reversal method shown.
[0047] Currently, major panel manufacturers are targeting high resolution, high display quality, low power consumption, and low cost for automotive TFT LCD panels. In view of this, an embodiment of the present invention provides an array substrate that maintains the advantages of low power consumption, high display quality, and low cost while maintaining high resolution.
[0048] The array substrate comprises: a driving circuit board, N rows and 2M columns of sub-pixels arranged in an array, 2N gate lines and M data lines, wherein the mth data line is connected to the 2m-1st and 2mth columns of sub-pixels respectively, the 8n+1th gate line is connected to the sub-pixels in the odd columns in the 4n+1th row, the 8n+2th gate line is connected to the sub-pixels in the even columns in the 4n+2th row, and the 8n+3th gate line is connected to the sub-pixels in the even columns in the 4n+1th row.

[0056] In a specific example, Figure 4 As shown, Figure 4 The driving structure of an array substrate provided by this embodiment is shown. It can be understood that: Figure 4 Only a partial drive architecture is shown.
[0057] The array substrate includes a driving circuit board (not shown in the figure), 6 rows and 8 columns of sub-pixels arranged in an array, 12 gate lines Gate1-Gate12 and 4 data lines Source1-Source4.

Figure 4 Taking the sub-pixel in the second row and second column as an example, the gate of its thin film transistor needs to cross the third gate line Gate3 and connect to the second gate line Gate2.

[0062] The first data line Source1 is set between the 1st and 2nd columns of sub-pixels; the second data line Source2 is set between the 3rd and 4th columns of sub-pixels; the third data line Source3 is set between the 5th and 6th columns of sub-pixels; and the fourth data line Source4 is set between the 7th and 8th columns of sub-pixels.
[0063] The driving circuit board is configured to drive the array of sub-pixels in a dot inversion manner, such as Figure 5 As shown, it is understandable that in actual driving, the voltage amplitude of the data signal varies. In this embodiment, the fixed amplitude of 5 is used as an example only for the convenience of explanation, because this embodiment mainly focuses on the number of switching times. The specific driving mode is:

[0077] As can be seen from the above-described driving method, the array substrate provided in this embodiment switches the voltage polarity of the data line data signal only once every four sub-pixels are charged. Compared to the existing dual gate + (1+2 Dot Inversion) inversion method, where the data line data signal switches the voltage polarity every time two sub-pixels are charged, the number of voltage polarity switches on the data line is reduced by half, thereby achieving the goal of reducing power consumption. Existing automotive TFT LCD panels generally require the customer to provide a 3.3V VDD voltage. The DC-DC circuits on the module's PCBA and FPCA first generate the VSP and VSN voltages, which are then generated by a charge pump circuit to generate the VGH and VGL voltages. In other words, driving a TFT LCD panel requires the VDD, VSP, VSN, VGH, and VGL voltages. However, for TFT LCD panels with lower power consumption, a separate charge pump circuit is not required; the array substrate's driver circuit board can suffice. Therefore, the use of this embodiment does not require the use of an additional charge pump circuit, which can save a large number of electronic components and thus achieve the purpose of reducing costs. While reducing power consumption and costs, the arrangement of sub-pixels also achieves true dot inversion, so this embodiment also has good quality performance such as low flicker and low crosstalk.
