[0048] Figure 1 It is a pixel design schematic diagram of a liquid crystal display panel provided by the prior art, such as Figure 1 As shown, in the existing pixel design, DBS_COM1 and the pixel electrode 2 are designed in the same layer, E1 can be the voltage applied by CF com (i.e., the common electrode) to the pixel electrode 2, Data Lin can be the data line responsible for transmitting data, and since there is coupling between Data Lin and the pixel electrode 2, black metal electrodes 3 are provided on both sides of Data Lin to reduce the coupling between the two. However, this scheme reduces the aperture ratio of the liquid crystal display panel due to the provided metal electrodes 3, and, using the above scheme, when the user squints at the liquid crystal display, the viewing angle effect is poor, and the product cost is increased.

[0049] Based on this, an embodiment of the present application provides a liquid crystal display panel, including an array substrate, a liquid crystal layer and a color film substrate. The liquid crystal display panel also includes a plurality of pixel areas arranged in an array. The pixel areas are divided into a main pixel area and a sub-pixel area. When displaying, the initial arrangement angles of the liquid crystal media of the liquid crystal layers corresponding to the main pixel area and the sub-pixel area are different, so that when driven by the same driving voltage, the rotation starting voltages of the main pixels in the main pixel area and the sub-pixels in the sub-pixel area are different.

[0050] In some embodiments, pixel electrodes corresponding to the pixel areas are provided on the array substrate. The pixel electrodes are divided into a main pixel electrode and a first pixel electrode, which are respectively provided in the main pixel area and the second pixel area. The main pixel electrode and the first pixel electrode are respectively electrically connected to the data line through a thin film transistor switch, and a second pixel electrode is also provided below the corresponding position of the first pixel electrode.

[0051] Figure 2 is a schematic diagram of a pixel design of a liquid crystal display panel provided by an embodiment of the present application, such as Figure 2 As shown, in this embodiment, DBS_COM and the pixel electrode can be arranged in different layers, which can shield or reduce the coupling between the Data Lin and the pixel electrode through the DBS and increase the aperture ratio.

[0052] like Figure 2 As shown in (a), in the main pixel area, DBS_COM4 can be set in a different layer from the main pixel electrode 5 and set at the edge of the main pixel electrode 5; Figure 2 As shown in (b), in the sub-pixel region, a whole layer of DBS_COM6 (i.e., the second sub-pixel electrode) can be arranged below the sub-pixel electrode 7 (i.e., the first sub-pixel electrode), that is, a data shielding layer can be arranged below each sub-pixel electrode 7, and the material of the data shielding layer can be indium tin oxide (ITO). At the same time, this embodiment can apply a certain voltage to the data shielding layer. In other words, it can be considered that an additional electrode is arranged on one side of each sub-pixel electrode 7. E1 can be the voltage applied by CF com (i.e., the common electrode) to the main pixel electrode 5, and E2 can be the voltage applied by CF com (i.e., the common electrode) to the sub-pixel electrode 7. Furthermore, due to the existence of the second sub-pixel electrode, there is a different voltage difference between the sub-pixel and the main pixel, so that different viewing angles or pre-tilt angles can be configured.

[0053] Furthermore, in some embodiments, the main pixel electrode and the first sub-pixel electrode are electrically connected to the data line via a thin film transistor switch respectively, and the main pixel region and the sub-pixel region each include four display domains.

[0054] Specifically, in this embodiment, each main pixel in the main pixel area may correspond to a thin film transistor, and each sub-pixel in the sub-pixel area may correspond to a thin film transistor. Figure 3 is a schematic diagram of another pixel design of a liquid crystal display panel provided by an embodiment of the present application, such as Figure 3 As shown in (a), each pixel may correspond to a thin film transistor, the left side Vpixel is the voltage applied by the common electrode, and the right side is the Data line responsible for transmitting data; Figure 3 As shown in (b), the main pixel area and the sub-pixel area can both include four display domains. The essence of the 8-domain viewing angle improvement is to allow the main pixel area and the sub-pixel area to have different liquid crystal medium rotation angles when displaying content, so that when the user squints, the angle between the eye light and the long axis of the liquid crystal medium is different in the main pixel area and the sub-pixel area in the 8-domain (such as θ1 and θ2), thereby achieving viewing angle optimization.

[0055] Figure 4 FIG. 1 is a flow chart of a control method of a liquid crystal display panel provided in an embodiment of the present application. As an example but not a limitation, the method can be applied to a liquid crystal display panel. Figure 4 As shown, the method includes:

[0056] S101 . During the process of displaying an image on a liquid crystal display panel, controlling a target voltage applied to a second sub-pixel electrode according to a first initial arrangement angle of a liquid crystal medium in a primary pixel region and a second initial arrangement angle of a liquid crystal medium in a secondary pixel region.

[0057] The first initial arrangement angle and the second initial arrangement angle can be respectively understood as the angles at which the liquid crystal medium in the primary pixel area and the secondary pixel area rotates when no voltage is applied. The specific angles can be configured during the production process of the liquid crystal display panel.

[0058] Specifically, in the process of the liquid crystal display panel displaying an image, the target voltage applied to the second sub-pixel electrode can be controlled according to the first initial arrangement angle of the liquid crystal medium in the main pixel area and the second initial arrangement angle of the liquid crystal medium in the sub-pixel area. For example, the target voltage can be controlled based on the specific values ​​of the first initial arrangement angle and the second initial arrangement angle. For example, the target voltage can be controlled by measuring whether the first initial arrangement angle and the second initial arrangement angle reach a preset angle, or the target voltage can be controlled by comparing the first initial arrangement angle and the second initial arrangement angle. The target voltage can also be controlled by detecting whether the first initial arrangement angle and the second initial arrangement angle are equal. This embodiment is not limited to this.

[0059] S102, inputting the same driving voltage to the first main pixel electrode and the first sub-pixel electrode through the data line, so that the rotation start voltages of the main pixel in the main pixel area and the sub-pixel in the sub-pixel area are different, so that the liquid crystal medium in the main pixel area and the liquid crystal medium in the sub-pixel area are arranged along different rotation angles.

[0060] In a specific embodiment, the same driving voltage can be input to the first main pixel electrode and the first sub-pixel electrode through the data line. Then, when the target voltage is determined, the main pixel in the main pixel area and the sub-pixel in the sub-pixel area can have different rotation starting voltages. Driven by different rotation starting voltages, the liquid crystal medium in the main pixel area and the liquid crystal medium in the sub-pixel area can be respectively controlled to perform angular deflection, so that the liquid crystal medium in the main pixel area and the liquid crystal medium in the sub-pixel area can be finally arranged along different rotation angles.

[0061] The present embodiment provides a control method for a liquid crystal display panel. In the process of displaying an image on the liquid crystal display panel, the target voltage applied to the second secondary pixel electrode is controlled according to the first initial arrangement angle of the liquid crystal medium in the main pixel area and the second initial arrangement angle of the liquid crystal medium in the sub-pixel area; the same driving voltage is input to the first main pixel electrode and the first secondary pixel electrode through the data line, so that the rotation start voltage of the main pixel in the main pixel area and the sub-pixel in the sub-pixel area are different, so that the liquid crystal medium in the main pixel area and the liquid crystal medium in the sub-pixel area are arranged at different rotation angles. By using this method, the rotation start voltage of the main pixel in the main pixel area and the sub-pixel in the sub-pixel area can be different under the same driving voltage, so that the liquid crystal medium in the main pixel area and the liquid crystal medium in the sub-pixel area can be arranged at different rotation angles, thereby optimizing the viewing angle effect of the liquid crystal display panel without increasing the product cost, and improving the refresh rate of the product.

[0062] Figure 5 This is a flow chart of a control method for a liquid crystal display panel provided by another embodiment of the present application. This embodiment further optimizes the control of the target voltage applied to the secondary pixel electrode according to the first initial arrangement angle of the liquid crystal medium in the main pixel area and the second initial arrangement angle of the liquid crystal medium in the secondary pixel area as follows: detecting whether the first initial arrangement angle is equal to the second initial arrangement angle to obtain a detection result; and controlling the target voltage applied to the secondary pixel electrode based on the detection result. Figure 5 As shown, the method includes:

[0063] S201 . During the process of displaying an image on a liquid crystal display panel, detecting whether a first initial arrangement angle is equal to a second initial arrangement angle, and obtaining a detection result.

[0064] S202 , controlling a target voltage applied to the second sub-pixel electrode based on the detection result.

[0065] S203, inputting the same driving voltage to the first main pixel electrode and the first sub-pixel electrode through the data line, so that the rotation start voltages of the main pixel in the main pixel area and the sub-pixel in the sub-pixel area are different, so that the liquid crystal medium in the main pixel area and the liquid crystal medium in the sub-pixel area are arranged along different rotation angles.

[0066] In a specific implementation, the target voltage can be controlled based on whether the first initial arrangement angle is equal to the second initial arrangement angle. That is, the target voltage can be controlled differently by detecting whether the first initial arrangement angle is equal to the second initial arrangement angle. Different detection results can correspond to different control schemes, so that the rotation start voltages of the primary and secondary pixels correspond to different values.

[0067] In some embodiments, controlling the second voltage applied to the second sub-pixel electrode based on the detection result includes:

[0068] If it is detected that the first initial arrangement angle is equal to the second initial arrangement angle, the voltage value of the second voltage is controlled to be non-zero.

[0069] In one embodiment, if it is detected that the first initial arrangement angle is equal to the second initial arrangement angle, it means that the liquid crystal medium in the main pixel area and the liquid crystal medium in the sub-pixel area are currently arranged along the same rotation angle, then the main pixel and the sub-pixel can be controlled to have different rotation start voltages, so that the liquid crystal medium in the main pixel area and the liquid crystal medium in the sub-pixel area can be controlled to be arranged along different rotation angles. For example, the same driving voltage can be input to the first main pixel electrode and the first sub-pixel electrode through the data line, and the voltage value of the second voltage can be controlled to be non-zero, so that the rotation start voltages of the main and sub-pixels can be unequal, so that the liquid crystal medium in the main pixel area and the liquid crystal medium in the sub-pixel area can be rotated at different angles on the basis of the same initial arrangement angle, and finally achieve the effect of arranging along different rotation angles.

[0070] In some embodiments, controlling the second voltage applied to the second sub-pixel electrode based on the detection result includes:

[0071] If it is detected that the first initial arrangement angle is not equal to the second initial arrangement angle, the voltage value of the second voltage is controlled to be zero.

[0072] In another embodiment, if it is detected that the first initial arrangement angle is not equal to the second initial arrangement angle, it means that the liquid crystal medium in the main pixel area and the liquid crystal medium in the sub-pixel area are currently arranged along different rotation angles. Then, the same driving voltage can be input to the first main pixel electrode and the first sub-pixel electrode through the data line, and the voltage value of the second voltage is controlled to be zero, so that the liquid crystal medium in the main pixel area and the liquid crystal medium in the sub-pixel area can be rotated by the same angle on the basis of different initial arrangement angles, and finally achieve the effect of arranging along different rotation angles.

[0073] A control method for a liquid crystal display panel provided in this embodiment controls the target voltage applied to the secondary pixel electrode by detecting whether the first initial arrangement angle is equal to the second initial arrangement angle, which can provide a voltage basis for subsequently arranging the liquid crystal medium in the main pixel area and the liquid crystal medium in the sub-pixel area along different rotation angles, thereby further optimizing the viewing angle effect of the liquid crystal display panel.

[0074] In some embodiments, before controlling the voltage value of the second voltage to be zero, the method further includes:

[0075] During the alignment process of the liquid crystal display panel, according to the alignment angle requirements, a first alignment voltage is input to the main pixel electrode and the first sub-pixel electrode, and a second alignment voltage is input to the second sub-pixel electrode, so that after the main and sub-pixels are aligned, the first initial arrangement angle is not equal to the second initial arrangement angle, wherein the voltage value of the second alignment voltage is not zero.

[0076] In some embodiments, after the primary and secondary pixels are aligned, the first initial arrangement angle is not equal to the second initial arrangement angle, including:

[0077] Controlling the liquid crystal medium in the main pixel region to deflect at an angle based on the first alignment voltage, and controlling the liquid crystal medium in the sub-pixel region to deflect at an angle based on the first alignment voltage and the second alignment voltage;

[0078] The deflected liquid crystal medium is irradiated with ultraviolet light to solidify the deflection angle of the deflected liquid crystal medium, so that after the primary and secondary pixels are aligned, the first initial arrangement angle is not equal to the second initial arrangement angle.

[0079] In a specific embodiment, during the alignment process of the liquid crystal display panel, the specific values ​​of the first initial arrangement angle of the liquid crystal medium in the main pixel area and the second initial arrangement angle of the liquid crystal medium in the sub-pixel area can be configured so that the first initial arrangement angle and the second initial arrangement angle are not equal. The specific configuration process is not limited and can be determined according to the actual configuration method. For example, during the production process of the liquid crystal display panel, different initial arrangement angles can be configured by controlling different alignment voltages. Specifically, the electric field force actually received by the liquid crystal medium can be regulated according to the voltage applied by DBS ITO, so as to achieve different pre-tilt angles of the liquid crystal medium during the alignment process.

[0080] Figure 6 FIG. 1 is a flow chart of configuring an initial arrangement angle according to an embodiment of the present application. Figure 6 As shown, the liquid crystal display panel may include an ITO electrode 8, a PI layer 9 (i.e., an alignment mold), a liquid crystal medium 10, and photosensitive molecules 11. After a voltage is applied to the liquid crystal display panel, the liquid crystal medium 10 and the photosensitive molecules 11 will rotate at a certain angle. Subsequently, the liquid crystal display panel may be irradiated with ultraviolet light, and the photosensitive molecules 11 will react with the PI layer 9 to form an angle, so that the liquid crystal medium 10 rotates similarly to the angle formed by the photosensitive molecules 11, so that the liquid crystal medium 10 can form an initial arrangement angle (i.e., a pretilt angle) for subsequent display applications.

[0081] Figure 7 is a schematic diagram of a corresponding relationship between a driving voltage and an initial arrangement angle provided by an embodiment of the present application, such as Figure 7As shown, the horizontal axis is the driving voltage corresponding to the pixel, and the vertical axis is the initial arrangement angle Pre-title configured by the liquid crystal medium of the pixel. For example, for the main pixel, when the voltage applied to the common electrode is 18V, the final alignment voltage corresponding to the main pixel can be 18V, then Figure 7 It can be seen that the initial arrangement angle of the liquid crystal medium of the main pixel is 1.8°; for the sub-pixel, when the voltage applied to the common electrode is 18V and the voltage applied to the second pixel electrode is 4V, the final alignment voltage corresponding to the sub-pixel can be 14V, then Figure 7 It can be seen that the initial arrangement angle of the liquid crystal medium of the sub-pixel is 1.1°.

[0082] In a specific implementation, this embodiment can input a first alignment voltage to the main pixel electrode and the first first pixel electrode, respectively, and input a second alignment voltage to the second second pixel electrode, so that the main and sub-pixel areas drive the liquid crystal medium to deflect at an angle according to the final alignment voltage, and use ultraviolet light to irradiate the deflected liquid crystal medium to solidify the deflection angle of the deflected liquid crystal medium, thereby making the first initial arrangement angle of the liquid crystal medium in the main pixel area unequal to the second initial arrangement angle of the liquid crystal medium in the sub-pixel area.

[0083] Figure 8 is a schematic diagram of a gamma curve provided by an embodiment of the present application, such as Figure 8 As shown, the gamma curves of the normal view, 1T+4 domain pixel design, 3T+8 domain pixel design and the present embodiment are shown. It can be seen that when the user squints at the LCD display, the gamma curve of the present embodiment is close to the gamma curve of the traditional 3T+8Domain, and is much better than the viewing angle performance of the 1T+4Domain pixel design.

[0084] From the above description, it can be found that in order to maintain a good viewing angle while improving the refresh rate, the present embodiment can configure different initial arrangement angles for the liquid crystal medium in the main pixel area and the liquid crystal medium in the sub-pixel area. By applying the same or different rotation start voltages to the main pixel and the sub-pixel, the main pixel and the sub-pixel can have different VT curves of liquid crystal media, so that even under the same driving voltage, because the liquid crystal media of the main pixel and the sub-pixel have different pre-tilt angles (i.e., initial arrangement angles), the liquid crystal medium in the main pixel area and the liquid crystal medium in the sub-pixel area can be arranged along different rotation angles, so that a higher operating frequency and lower power consumption can be easily achieved through the pixel design of 1T+8 domains, and a better viewing angle performance can be achieved on the basis of reducing the load. In addition, the aperture ratio can be improved by eliminating the SM metal.

[0085] In summary, the control method of the liquid crystal display panel provided in this embodiment provides a 1T+8 domain pixel design with reduced load, and optimizes the pre-tilt angles of the main pixel and the sub-pixel by combining the process method, thereby maintaining a viewing angle performance close to that of 3T+8Doamin, making it more suitable for application scenarios requiring wide viewing angle and high contrast. At the same time, the liquid crystal display panel provided in this embodiment also improves the aperture ratio, improves the panel penetration rate, reduces data loading, improves display power consumption, and improves product competitiveness.
