Fig. 4 is a schematic diagram of an array substrate and a color filter substrate provided in this embodiment, as shown in fig. 4, the color filter substrate 2 may include data lines D ' 1, D ' 2, D ' 3, and D ' 4, gate lines G ' 1, G ' 2, and G ' 3, common electrodes COM1, COM2, and COM3, a plurality of TFT switches 41 and via holes 30, and the array substrate 3 may include data lines D1, D2, D3, and D4, gate lines G1, G2, and G3, pixel electrodes PXL1, PXL2, and PXL3, a plurality of TFT switches 42, and via holes 38.
The same column of pixel electrodes corresponds to a column of common electrodes, and in the column direction, each column of pixel electrodes and the common electrodes of the corresponding column are arranged in a staggered mode. The projection area of each pixel electrode on the substrate 21 of the color filter substrate 2 is partially overlapped with the projection areas of two corresponding adjacent common electrodes on the substrate 21 of the color filter substrate 2 in the column direction, and each overlapped area corresponds to different display units (i.e., Q1, Q2, Q3, Q4, etc.) of the liquid crystal display panel. Therefore, a pixel electrode can form a vertical electric field with two corresponding adjacent common electrodes in the column direction, if different voltages are output to the two adjacent common electrodes, different gray scales can be displayed in display areas (namely two display units) corresponding to the two vertical electric fields, namely the display area corresponding to the pixel electrode can display two different gray scales in the column direction, and compared with the situation that only one gray scale can be displayed in the column direction in the display area corresponding to the current pixel electrode, the resolution ratio of the liquid crystal display device can be doubled in the column direction.
In the column direction, the interval between adjacent common electrodes can be smaller than a first threshold value, so that the interval area between two vertical electric fields formed by the pixel electrode and the corresponding adjacent common electrode is not too large, the area of a display area corresponding to the pixel electrode can be ensured, and the aperture opening ratio of the liquid crystal display device is favorably improved.
In the row direction, the adjacent pixel electrodes can correspond to different common electrodes, so that the voltage of the pixel electrode corresponding to one display area can be adjusted, and the voltage of the common electrode corresponding to the display area can also be adjusted, so that the display area displays a corresponding gray scale, and the flexibility of the liquid crystal display device during display is improved; in the row direction, the adjacent pixel electrodes may also correspond to the same common electrode to reduce the complexity of the product, and this implementation will be exemplified by the case where the adjacent pixel electrodes correspond to different common electrodes in the row direction.
In the column direction, the projection of the center line between the boundaries of the adjacent common electrodes on the color filter substrate 2 on the substrate thereof may overlap the projection of the center line of the corresponding pixel electrode on the substrate in the row direction, for example, the adjacent common electrodes COM2 and COM3 on the color filter substrate 2 correspond to the pixel electrode PXL2 on the array substrate 3, and the projection of the center line between the boundaries of the common electrodes COM2 and COM3 on the substrate of the color filter substrate 2 overlaps the projection of the center line of the pixel electrode PXL2 on the substrate in the row direction. Therefore, the lengths of the two vertical electric fields corresponding to one pixel electrode in the column direction are equal, that is, the areas of the display regions corresponding to one pixel electrode and used for displaying two different gray scales are equal, so that the display effect of the liquid crystal display device is improved.
A projection area of the first metal layer 22 of the color filter substrate 2 on the base substrate of the color filter substrate 2 may overlap with a projection area of the first metal layer 32 of the array substrate 3 on the base substrate; the projection area of the second metal layer 25 of the color filter substrate 2 on the base substrate may overlap with the projection area of the second metal layer 35 of the array substrate 3 on the base substrate. In this way, the TFT switch 41 formed by the first metal layer 22 and the second metal layer 25 of the color filter substrate 2 and the TFT switch 42 formed by the first metal layer 32 and the second metal layer 35 of the array substrate 3 are overlapped in a direction perpendicular to the color filter substrate 2, so that the shielding of light can be reduced, the area through which the light passes can be increased, and the aperture opening ratio of the liquid crystal display device can be improved.
The via holes 38, the data lines, the gate lines, etc. on the array substrate 3 may also be overlapped with the corresponding via holes 30, data lines, and gate lines on the color film substrate 2 in a direction perpendicular to the color film substrate 2, for example, the data lines D1 of the array substrate 3 and the data lines D '1 of the color film substrate 2 are overlapped in a direction perpendicular to the color film substrate 2, and the gate lines G1 of the array substrate 3 and the gate lines G' 1 of the color film substrate 2 are also overlapped in a direction perpendicular to the color film substrate 2. This can further improve the aperture ratio of the liquid crystal display device.
The following describes a driving method of a liquid crystal display panel provided in an embodiment of the present application.
When the liquid crystal display panel is driven to display, a progressive scanning mode can be adopted. If the liquid crystal display panel is scanned to the Nth row and the Mth column of the liquid crystal display panel, the second voltage of the second electrode corresponding to the display unit can be determined according to the pre-display gray scale of the display unit in the Nth row and the Mth column and the first voltage of the first electrode corresponding to the display unit. When the first electrode is a common electrode, the second electrode is a pixel electrode; when the first electrode is a pixel electrode, the second electrode is a common electrode. M and N are positive integers.
After determining the second voltage, outputting the second voltage to the second electrode.
For example, at time T1, the gate line G1 is turned on first, and the data line D1 inputs a data voltage to the pixel electrode PXL1 through the TFT switch; then, determining the voltage of the common electrode COM2 according to a first pre-display gray scale corresponding to an overlapping portion (i.e., a display unit Q1) of the projection area of the pixel electrode PXL1 and the common electrode COM2 on the substrate 21 of the color filter substrate 2 and the data voltage of the pixel electrode PXL 1; then, the voltage is input to the common electrode COM2, and a vertical electric field is formed between the pixel electrode PXL1 and the common electrode COM2 at this time, liquid crystal in the vertical electric field is deflected, the display unit Q1 displays the first pre-display gray scale, and the area of the display unit Q1 is half of that of the display unit of the conventional pixel.
At a time T2, the voltage of the pixel electrode PXL2 is determined according to the second pre-display gray scale corresponding to the overlapping portion (i.e., the display cell Q2) of the projection areas of the pixel electrode PXL2 and the common electrode COM2 on the base substrate 21 of the color filter substrate 2, and the voltage of the common electrode COM 2; then, the voltage is input to the pixel electrode PXL2, and a vertical electric field is formed between the pixel electrode PXL2 and the common electrode COM2 at this time, liquid crystal in the vertical electric field is deflected, and the display unit Q2 displays the second pre-display gray scale.
At a time T3, a voltage of the common electrode COM3 is determined according to a third pre-display gray scale corresponding to an overlapping portion (i.e., the display unit Q3) of the projection areas of the pixel electrode PXL2 and the common electrode COM3 on the base substrate 21 of the color filter substrate 2 and a voltage of the pixel electrode PXL 2; then, when the voltage is input to the common electrode COM3, a vertical electric field is formed between the pixel electrode PXL2 and the common electrode COM3, liquid crystal in the vertical electric field is deflected, and the display cell Q3 displays a third pre-display gray scale.
At a time T4, determining a voltage of the common electrode COM4 according to a fourth pre-display gray scale corresponding to an overlapping portion (i.e., the display unit Q4) of the pixel electrode PXL3 and the common electrode COM3 in a projection area on the substrate 21 of the color filter substrate 2, and the voltage of the common electrode COM 3; then, when the voltage is input to the common electrode COM4, a vertical electric field is formed between the pixel electrode PXL3 and the common electrode COM4, liquid crystal in the vertical electric field is deflected, and the display unit Q4 displays a fourth pre-display gray scale.
And so on, the liquid crystal display panel is lighted line by line.
It can be understood that the array substrate 3 and the color filter substrate 2 provided in the embodiments of the present application may include more data lines, gate lines, pixel electrodes, common electrodes, TFT switches, and via holes than those in fig. 4, which are only exemplary illustrations.
When the liquid crystal display device displays, the pixel electrodes and the common electrodes of each row can be alternately charged according to the pre-display gray scale so as to display different gray scales. At this time, due to the difference in signal input time between the adjacent pixel electrodes, liquid crystal between the vertical electric fields corresponding to the adjacent pixel electrodes may be disturbed, and the display effect may be affected, so as shown in fig. 5, a light shielding unit 43 may be disposed between the adjacent pixel electrodes in the column direction of the array substrate 3, so as to reduce the influence of the liquid crystal disturbance between the vertical electric fields corresponding to the adjacent pixel electrodes on the display effect.
The technical scheme provided by the embodiment of the application comprises an array substrate, a color film substrate and a liquid crystal layer, wherein the array substrate and the color film substrate are oppositely arranged, and the liquid crystal layer is positioned between the array substrate and the color film substrate; the common electrode layer of the color film substrate comprises a plurality of common electrodes arranged in an array mode, the pixel electrode layer of the array substrate comprises a plurality of pixel electrodes arranged in an array mode, the same row of pixel electrodes correspond to one row of common electrodes, each row of pixel electrodes and the corresponding row of common electrodes are arranged in a staggered mode in the row direction, the projection area of each pixel electrode on the substrate of the color film substrate is partially overlapped with the projection areas of two corresponding adjacent common electrodes on the substrate in the row direction, and each overlapped area corresponds to different display units of the liquid crystal display panel. In the above technical solution, each row of pixel electrodes and the corresponding row of common electrodes are arranged in a staggered manner in the column direction, so that a vertical electric field can be formed between one pixel electrode and two corresponding adjacent common electrodes in the column direction, and if different voltages are output to the two adjacent common electrodes, different gray scales can be displayed in the display regions (i.e. two display units) corresponding to the two vertical electric fields, i.e. the display region corresponding to one pixel electrode can display two different gray scales in the column direction.
