In the display panel 10 shown in fig. 1 of the present invention, a data line is added to each row of pixel units, so as to perform differential power supply on the odd-numbered row of pixel units and the even-numbered row of pixel units, for example, the first-type data line 1021 controls the voltage of the odd-numbered row of pixel units, and the second-type data line 1022 controls the voltage of the even-numbered row of pixel units, so that the liquid crystal alignment of each row of the same row of pixel units is differentiated, thereby performing a four-domain (4-domain) design on the display panel 10 to achieve an eight-domain (8-domain) display effect, avoiding the configuration of additional thin film transistors, and simplifying the process design and the process steps.
Referring to fig. 2, fig. 2 is a schematic diagram of a second structure of the display panel 10 according to the present invention. The pixel unit 103 comprises a red pixel unit 103a, a green pixel unit 103b and a blue pixel unit 103c, wherein the first-class data line 1021 comprises a first red pixel data line 1021a, a first green pixel data line 1021b and a first blue pixel data line 1021c, the second-class data line 1022 comprises a second red pixel data line 1022a, a second green pixel data line 1022b and a second blue pixel data line 1022c, the first red pixel data line 1021a and the second red pixel data line 1022a input signals to the red pixel unit 103a, the first green pixel data line 1021b and the second green pixel data line 1022b input signals to the green pixel unit 103b, and the first blue pixel data line 1021c and the second blue pixel data line 1022c input signals to the blue pixel unit 103 c.

The first red pixel data line 1021a and the second red pixel data line 1022a are arranged adjacently and intersect with each other to form a red pixel region 104a, the red pixel unit 103a is arranged in the red pixel region 104a, the first blue pixel data line 1021c and the second blue pixel data line 1022c are arranged adjacently and intersect with each other to form a blue pixel region 104c, the blue pixel unit 103c is arranged in the blue pixel region 104c, the first green pixel data line 1021b and the second green pixel data line 1022b are arranged adjacently and intersect with each other to form a green pixel region 104b, and the green pixel unit 103b is arranged in the green pixel region 104 b.
In one embodiment, the red pixel cells 103a are arranged in the same column and the green pixel cells 103b and the blue pixel cells 103c are arranged in the same column. To explain with the red pixel unit 103a, since the first red pixel data line 1021a and the second red pixel data line 1022a are adopted by the red pixel units 103a in the odd-numbered rows and the even-numbered rows to input signals respectively, voltages input by the red pixel units 103a and the red pixel units 103a in the adjacent rows may be different, and thus deflection angles of liquid crystals in corresponding regions of the red pixel units 103a and the red pixel units 103a in the adjacent rows are different, so that red displayed by the red pixel units 103a and the red pixel units 103a in the adjacent rows are slightly different, and the green pixel units 103b and the blue pixel units 103c are also the same. Therefore, in the display panel 10 of fig. 2, the data lines 102 are respectively disposed on two sides of each row of the same-color pixel units, and the odd-numbered rows of pixel units and the even-numbered rows of pixel units are differentially powered, so that the display panel 10 achieves an eight-domain (8-domain) display effect.
Referring to fig. 3, fig. 3 is a third structural schematic diagram of the display panel 10 according to the present invention. The first red pixel data line 1021a and the second red pixel data line 1022a are arranged adjacent to each other to form a red pixel data line group 102a, the red pixel data line group 102a is disposed between the pixel unit 103 and the pixel unit 103, the first green pixel data line 1021b and the second green pixel data line 1022b are arranged adjacent to each other to form a green pixel data line group 102b, the green pixel data line group 102b is disposed between the pixel unit 103 and the pixel unit 103, the first blue pixel data line 1021c and the second blue pixel data line 1022c are arranged adjacent to each other to form a blue pixel data line group 102c, and the blue pixel data line group 102c is disposed between the pixel unit 103 and the pixel unit 103.
In one embodiment, the red pixel cells 103a are arranged in the same column and the green pixel cells 103b and the blue pixel cells 103c are arranged in the same column. To explain with the red pixel unit 103a, since the first red pixel data line 1021a and the second red pixel data line 1022a are adopted by the red pixel units 103a in the odd-numbered rows and the even-numbered rows to input signals respectively, voltages input by the red pixel units 103a and the red pixel units 103a in the adjacent rows may be different, and thus deflection angles of liquid crystals in corresponding regions of the red pixel units 103a and the red pixel units 103a in the adjacent rows are different, so that red displayed by the red pixel units 103a and the red pixel units 103a in the adjacent rows are slightly different, and the green pixel units 103b and the blue pixel units 103c are also the same. Therefore, in the display panel 10 of fig. 3, a data line is correspondingly added beside the original data line 102 for each row of same-color pixel units, and differential power supply is performed on the odd-numbered row of pixel units and the even-numbered row of pixel units, so that the display panel 10 achieves an eight-domain (8-domain) display effect.
The display panel 10 provided by the invention adopts two specific arrangement modes of fig. 2 or fig. 3, can adapt to different display panels, is convenient for wiring design, and selects a wiring mode which can reduce the wiring area and improve the in-plane utilization rate of the panel when being connected with a circuit module. The essence of the present invention is to use different data lines to control the pixel cells in different rows to achieve multi-domain alignment, and the derived wiring manner is within the scope of the present invention without departing from the spirit of the present invention.
The first data voltage of the display panel 10 includes a first red data voltage, a first green data voltage, and a first blue data voltage, the second data voltage includes a second red data voltage, a second green data voltage, and a second blue data voltage, the first red pixel data line 1021a is connected to the first red data voltage, the second red pixel data line 1022a is connected to the second red data voltage, the first green pixel data line 1021b is connected to the first green data voltage, the second green pixel data line 1022b is connected to the second green data voltage, the first blue pixel data line 1021c is connected to the first blue data voltage, and the second blue pixel data line 1022c is connected to the second blue data voltage.
The data lines 102 controlling the pixel units 103 with different colors are connected to different or the same data voltages, so that the pixel units 103 with different colors can form an angle difference in advance in the liquid crystal alignment process. For example, the first red data voltage and the first green data voltage have different values, and the red pixel units 103a and the green pixel units 103b in the same row directly generate an angle difference during alignment, so that the alignment angle is more varied, and the display effect of the liquid crystal display panel can be better.
Wherein a difference between the first red data voltage and the first blue data voltage is more than 2V, a difference between the first red data voltage and the first green data voltage is more than 2V, and/or a difference between the first blue data voltage and the first green data voltage is more than 2V.

The voltage value of each data line 102 is set according to the specific display panel requirements, so that different display panels can achieve better display effects.

In an embodiment of the present invention, the difference between the first data voltage and the second data voltage is set to be 3V, but the voltage inputted to the common electrode of the display panel 10 is 5V, so that different voltages are applied to different pixel cell regions controlled by the first type data line and the second type data line, that is, the voltage of the corresponding pixel cell of the input signal of the first type data line is 5V, and the voltage of the corresponding pixel cell of the input signal of the second type data line is 2V.
