Technological innovation has never ceased. With the continuous upgrading of television products and the increasing demands from users, competition in the display panel industry has intensified in recent years, especially in the pursuit of low cost, high transmittance, and high contrast. Summary of the Invention

[0004] In a first aspect, embodiments of this application provide a liquid crystal display substrate, the substrate comprising:

[0005] A grid line, a data line, and a pixel array defined by the intersection of the grid line and the data line, the pixel array including a first type of pixel and a second type of pixel, wherein the first type of pixel and the second type of pixel are arranged alternately in the same pixel row;

[0006] Class I voltage lines, Class II voltage lines

[0007] Each of the first type of voltage lines connects to the first type of pixels in the pixel row corresponding to that first type of voltage line.

[0008] Each of the second type voltage lines connects to the second type pixels in the pixel row corresponding to the second type voltage line;

[0009] Each row of pixels corresponds to one first type of voltage line and one second type of voltage line.

[0010] In one possible implementation, each of the first type of voltage lines provides a first voltage signal to the first type of pixel connected to the first type of voltage line during odd-numbered periods, and provides a second voltage signal to the first type of pixel connected to the first type of voltage line during even-numbered periods.

[0011] Each of the second type of voltage lines provides a second voltage signal to the second type of pixels connected to the second type of voltage line in the same odd-numbered period, and provides a first voltage signal to the second type of pixels connected to the second type of voltage line in the same even-numbered period.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0034] Response time is a key competitive factor for display panels. On one hand, response time directly affects image quality issues such as image ghosting; on the other hand, response time also severely restricts the choice of product design solutions such as high resolution (8K+), high refresh rate (120Hz+), and high contrast, preventing significant performance improvements in high-end products. Therefore, shortening response time can increase a product's overall competitiveness.

[0035] The calculation formulas for various parameters of an LCD display panel can be as follows: Figure 1 As shown, based on the Figure 1 The analysis shows that to shorten the response time RT of a liquid crystal display panel, while keeping parameters ε0 and E constant, it is necessary to reduce the liquid crystal viscosity γ1, the liquid crystal cell thickness d, and the liquid crystal elastic coefficient K. 22 Alternatively, the dielectric constant Δε of the liquid crystal can be increased. However, from the formula for calculating the transmittance Tr of the liquid crystal display panel, it can be concluded that, with other parameters remaining constant, decreasing the thickness d of the liquid crystal cell will decrease the transmittance of the liquid crystal display panel. To ensure the transmittance of the liquid crystal display panel, the thickness d of the liquid crystal cell must be above the thickness value that meets the transmittance requirements; therefore, the cell thickness d cannot be arbitrarily reduced. If it is necessary to shorten the response time of the liquid crystal display panel, it can be considered from three dimensions: the elastic coefficient K22 of the liquid crystal, the viscosity γ1 of the liquid crystal, and the dielectric constant Δε of the liquid crystal. Furthermore, from the formula for calculating the driving voltage Vop of the liquid crystal substrate, it can be seen that, with other parameters remaining constant, increasing the elastic coefficient K22 of the liquid crystal will decrease the transmittance. 22 The driving voltage Vop will increase. Through analysis of various parameters of the liquid crystal display panel and reverse reasoning, it can be deduced that, with other parameters remaining constant, increasing the driving voltage increases the elastic coefficient of the liquid crystal, thereby shortening the response time of the liquid crystal display panel. Therefore, increasing the driving voltage Vop of the liquid crystal substrate can unlock the design limitations of the liquid crystal, thereby shortening the response time of the liquid crystal display panel and improving the competitiveness of liquid crystal display products.

[0036] Based on the above regarding Figure 1 Analysis of the parameters in the formula shows that increasing the driving voltage Vop of the liquid crystal display substrate can shorten the response time of the liquid crystal display panel. Since the driving voltage Vop of the liquid crystal display substrate is the difference between the Source voltage and the Vcom voltage, the Vcom voltage can be adjusted to increase the driving voltage Vop of the liquid crystal display substrate without changing the Source voltage.

[0037] However, in related technologies, display panels typically employ a DC driving method using Vcom voltage (common voltage). This means the Vcom voltage is a fixed value, providing a reference voltage for the deflection of liquid crystal molecules. When the Source voltage is above the Vcom voltage, the liquid crystal is positive; when the Source voltage is below the Vcom voltage, the liquid crystal is negative. For example... Figure 2 As shown, the polarity is negative in frames N and N+2, and positive in frames N+1 and N+3. (Source voltage (corresponding to...)) Figure 2 The difference between the V0-V255 voltage and the Vcom voltage is used to display different gray levels between 0 and 255. In related technologies, the Vcom voltage is typically around 8.5V, and the Source voltage (the voltage of the Data signal) ranges from approximately 0.2V to 17.2V. The difference between the Source voltage and the Vcom voltage displays different gray levels between V0 and V255. For example, when the Source voltage is 17.2V and the Vcom voltage is 8.5V, the difference between the Source voltage and the Vcom voltage is 8.7V, corresponding to a gray level of 255. Since the Source voltage is higher than the Vcom voltage, this is a positive polarity. When the Source voltage is 0.2V and the Vcom voltage is 8.5V, the difference between the Source voltage and the Vcom voltage is -8.3V, corresponding to a gray level of 255. Since the Source voltage is lower than the Vcom voltage, this is a negative polarity. The closer the Source voltage is to the Vcom voltage, the smaller the difference between the Source voltage and the Vcom voltage, and the smaller the corresponding gray level. For example, when the Source voltage is 8.6V, the corresponding gray level is 0. The inversion of positive and negative frames in a liquid crystal is achieved by positioning the Source voltage above or below the Vcom voltage, while maintaining a constant voltage difference between the Source voltage and the Vcom voltage during the frame inversion process, thereby ensuring that the brightness of the liquid crystal display remains constant. A schematic diagram of the positive and negative frame inversion in related technologies is shown below. Figure 3 As shown, however, LCD panels using the frame inversion method suffer from significant flickering, which affects the product's display performance.

[0038] As can be seen from the above analysis, under the DC driving mode with Vcom voltage, for example, when Vcom voltage is about 8.5V and the Source voltage ranges from about 0.2V to 17.2V, the voltage value of the driving voltage Vop of the liquid crystal display substrate (the difference between the Source voltage and the Vcom voltage) can reach a maximum of about 8.7V. Due to the mutual limitations between the various parameters of the liquid crystal display panel, the response time of the liquid crystal display panel cannot be further reduced.

[0039] To further reduce the response time of a liquid crystal display (LCD) panel, it is necessary to increase the driving voltage Vop of the LCD substrate. Therefore, this application provides an LCD substrate that increases the driving voltage Vop of the LCD substrate by setting the LCD panel to two types of Vcom lines (a first type of voltage line and a second type of voltage line). The two types of Vcom lines provide voltage signals with different voltage values ​​(a first voltage signal and a second voltage signal) and the voltage values ​​are interchanged in different periods (odd periods and even periods). A column inversion method is adopted, and a column architecture or a Z architecture is used. Under these circumstances, the limitations in the LCD design process are reduced, and the limits of LCD design can be released, thereby achieving the goal of shortening the response time of the LCD panel.

[0040] The two types of Vcom lines in this application are the first type of voltage line and the second type of voltage line. In actual design, the first type of voltage line and the second type of voltage line can be named according to design requirements or the designer's habits. In one example, the first type of voltage line is named Vcom E, and the second type of voltage line is named Vcom O. Column inversion means that the same pixel column in the display area of ​​the liquid crystal display panel has the same polarity within the same frame. Column architecture means that all pixels in the same pixel column have the same polarity. Z architecture means that the first type of pixels and the second type of pixels in the same pixel column are arranged alternately.

[0041] The following are three specific implementation methods for liquid crystal display substrates:

[0042] Implementation Method 1: Implementation Method 1 of this application adopts a Dual Vcom + Column Inversion + Column architecture. Dual Vcom indicates that the liquid crystal display substrate in this application is configured with two types of Vcom lines: a first type of voltage line and a second type of voltage line. These two types of Vcom lines provide voltage signals with different voltage values, and the voltage values ​​are interchanged in different periods (odd and even periods). The Column Inversion + Column architecture means that the polarity of each pixel in the same pixel column is the same, and the polarity of the same pixel column is the same in the same frame, while the polarity of the same pixel column is opposite in two adjacent frames.

[0043] In this embodiment, the liquid crystal display substrate includes a pixel array, first type voltage lines, and second type voltage lines. The pixel array includes multiple pixels, which are divided into first type pixels and second type pixels. Each first type voltage line corresponds to two adjacent pixel rows, and each second type voltage line corresponds to two adjacent pixel rows. Each first type voltage line connects to each first type pixel in its corresponding pixel row, and each second type voltage line connects to each second type pixel in its corresponding pixel row. First type pixels and second type pixels are arranged alternately in the same pixel row, and pixels of the same type are in the same pixel column. The structures of first type pixels and second type pixels can be the same, but when displaying the same frame, the polarities of the first type pixels and second type pixels are opposite.

[0044] See Figure 4 Let Vcom E represent a first-class voltage line and Vcom O represent a second-class voltage line. First-class voltage lines include Vcom E1, Vcom E2, Vcom E3…Vcom Ei…Vcom En, where Vcom Ei represents the i-th first-class voltage line. Second-class voltage lines include Vcom O1, Vcom O2, Vcom O3…Vcom Oi…Vcom On, where Vcom Oi represents the i-th second-class voltage line. "+" pixels are positive pixels corresponding to first-class pixels, and "-" pixels are negative pixels corresponding to second-class pixels. Figure 4 The diagram illustrates vertically arranged data lines, horizontally arranged gate lines, and the different pixels defined by their intersection. Each pixel row corresponds to one Vcom O and one Vcom E. One Vcom O corresponds to two pixel rows (there are no pixel rows above Vcom O1, so the first Vcom O1 corresponds only to the row below it), and one Vcom E corresponds to two pixel rows (there are no pixel rows below Vcom En, so Vcom En corresponds only to the row above it). The liquid crystal display substrate can be divided into a display area and a non-display area, with the pixel array located in the display area. In the non-display area, two buses, Vcom E and Vcom O, can be set. Each Vcom E in the display area needs to be connected to the Vcom E bus in the non-display area, and each Vcom O in the display area needs to be connected to the Vcom O bus in the non-display area. The buses can be located in the non-display area to the left or right of the display area. Figure 4 The method of setting the bus in the non-display area to the left of the display area is only an example. The method of setting the bus in other non-display areas is within the protection scope of this application.

[0045] Vias in the display area are used to connect different types of pixels to their corresponding Vcom lines. See Figure 4In the first row of pixels, each second-type pixel is connected to Vcom O1, and each first-type pixel is connected to Vcom E1 via a via. In the second row of pixels, each first-type pixel is connected to Vcom E, and each second-type pixel is connected to Vcom O2 via a via. Then, Vcom E1 and Vcom E2 between pixel rows in the display area are connected to the Vcom E bus in the non-display area, and Vcom O1 and Vcom O2 between pixel rows in the display area are connected to the Vcom O bus in the non-display area. It is understood that the diagram only shows a portion of the Vcom O and Vcom E connection methods; the connection methods of the liquid crystal display substrate are a repetition of the shown portion. Through the two Vcom buses in the non-display area and the vias in the display area, all Vcom O pixels in the liquid crystal display substrate are connected together, and all Vcom E pixels are connected together, ensuring the uniformity of the substrate's Vcom.

[0046] Specifically, each Vcom O connects to the second type of pixels in its corresponding pixel row. For example, for any Vcom O other than the first one, this Vcom O connects to the second type of pixels in the pixel row above it and to the second type of pixels in the pixel row below it, specifically by connecting to the Vcom voltage terminals of the second type of pixels. Figure 4 As shown, because there are grid lines arranged in the middle of Vcom O and the pixel row above it, Vcom O needs to be connected to each of the second type pixels in the pixel row above it through vias. Assuming there are X second type pixels in the pixel row above Vcom O, this requires X vias. Each via is used to connect the Vcom voltage terminal of a second type pixel to Vcom O.

[0047] Vcom E connects to each first-type pixel in its corresponding pixel row. For example, for any Vcom E except the last one, the Vcom E connects to each first-type pixel in the pixel row above it and to each first-type pixel in the pixel row below it, specifically by connecting to the Vcom voltage terminal of the first-type pixel. Figure 4 As shown, because there are grid lines arranged in the middle of Vcom E and the pixel row above it, Vcom E needs to be connected to each of the first-class pixels in the pixel row above it through vias. Assuming there are X first-class pixels in the pixel row above Vcom E, this requires X vias. Each via is used to connect the Vcom voltage terminal of a first-class pixel to Vcom E.

[0048] In the embodiments of this application, the liquid crystal display panel is configured with two types of Vcom lines: a first type of voltage line and a second type of voltage line, denoted as Vcom E and Vcom O, respectively. It is understood that in actual design, the first and second types of voltage lines can be named according to design requirements or the designer's habits; Vcom E and Vcom O here are merely examples. The two Vcom lines provide voltage signals with different voltage values: for example, Vcom O is 0V and Vcom E is 16V. During the blank area at the end of a frame, the voltage values ​​of Vcom E and Vcom O are interchanged to ensure that the brightness of the liquid crystal display screen does not change. For example, in the first frame, Vcom O is 0V and Vcom E is 16V; in the second frame, Vcom O is 16V and Vcom E is 0V.

[0049] During the Vcom voltage reversal process between two adjacent frames, the polarity of the pixel circuit also reverses, see [link / reference]. Figure 6 In the current frame, the first column is always positive. After the Vcom voltage reverses, the first column in the next frame reverses to negative. Similarly, in the current frame, the second column is always negative. After the Vcom voltage reverses, the second column in the next frame reverses to positive. During the Vcom voltage reversal process between adjacent frames, the difference between the Source voltage and the Vcom voltage is displayed in different grayscale levels between 0 and 255. See [link / reference]. Figure 5 In frame N, the Vcom voltage is 18V, and the Source voltage ranges from 0.2V to 17.2V. When the Source voltage is 0.2V, the voltage difference is -17.8V, and the corresponding grayscale is 255. Since the Source voltage is lower than the Vcom voltage, it is negative when it is below the Vcom voltage. When the Source voltage is 17.2V, the voltage difference is -0.8V, and the corresponding grayscale is 0. Since the Source voltage is lower than the Vcom voltage, it is negative when it is below the Vcom voltage. In frame N+1, the Vcom voltage is 0V, and the Source voltage ranges from 0.2V to 17.2V. When the Source voltage is 0.2V, the voltage difference is 0.2V, and the corresponding grayscale is 0. Since the Source voltage is higher than the Vcom voltage, it is positive when it is above the Vcom voltage. When the Source voltage is 17.2V, the voltage difference is 17V, and the corresponding grayscale is 255. Since the Source voltage is higher than the Vcom voltage, it is positive when it is above the Vcom voltage.

[0050] In the embodiments of this application, the liquid crystal display panel is configured with two types of Vcom lines, each providing a voltage signal with a different voltage value. In this embodiment, the first voltage signal ranges from 16-18V; for example, the first voltage signal can be 16V, 16.5V, 17V, 18V, or any value in between. The second voltage signal ranges from 0-2V; for example, the second voltage signal can be 0V, 0.5V, 1V, 2V, or any value in between. The driving voltage Vop of the liquid crystal display substrate can be increased to 0-16V; for example, the driving voltage Vop can be 0V, 2V, 3V, 6V, 16V, or any value in between. By increasing the driving voltage Vop of the liquid crystal display substrate, the limits of liquid crystal design can be further expanded. The range of various parameters of the liquid crystal display panel can be adjusted as follows: the liquid crystal viscosity γ1 in the liquid crystal display substrate ranges from 55 mPa·s to 67 mPa·s. For example, the liquid crystal viscosity γ1 can be 55 mPa·s, 57 mPa·s, 59 mPa·s, 61 mPa·s, 67 mPa·s, or any value between these values. The liquid crystal dielectric constant Δε ranges from -1.2 to -1.4. For example, the liquid crystal dielectric constant Δε can be -1.2, -1.25, -1.35, -1.4, or any value between these values. The liquid crystal cell thickness d ranges from 3.0 μm to 3.2 μm. For example, the liquid crystal cell thickness d can be 3.0 μm, 3.05 μm, 3.1 μm, 3.15 μm, 3.2 μm, or any value between these values. The liquid crystal elastic coefficient K... 22 The value range is 10 Pa to 11.2 Pa (Pascals), for example, the elastic coefficient K of liquid crystal. 22 The value can be 10 Pa, 10.5 Pa, 10.7 Pa, 11.2 Pa, or any value in between. This allows the response time range of the LCD panel to be adjusted as follows: start duration t on The range is 7.25ms-14.5ms, for example, the start duration t. on The duration can be: 7.25ms, 8.5ms, 10.5ms, 12.5ms, 14.5ms, or any value in between, with a final duration t. off The range is 8.45ms-16.9ms, for example, the duration t at the end. off The response time can be 8.45ms, 9.5ms, 12.5ms, 14.5ms, 16.9ms, or any value in between. This achieves the goal of shortening the response time of the LCD panel.

[0051] In one example, when the first voltage signal is 16V and the second voltage signal is 0V, the driving voltage Vop ranges from 0 to 16V. The liquid crystal viscosity γ1 is 55 mPa·s, the liquid crystal dielectric constant Δε is -1.2, the liquid crystal cell thickness d is 3.0 μm, and the liquid crystal elastic coefficient K... 22 When the Pa is 10, the initial duration t on It lasts for 7.25ms, and the duration at the end is t. off The response time is 8.45ms. At this value, the response time of the LCD panel is relatively short, thus achieving the goal of reducing the overall response time of the LCD panel.

[0052] In one example, when the first voltage signal is 18V and the second voltage signal is 2V, the driving voltage Vop ranges from 0 to 16V. The liquid crystal viscosity γ1 is 67 mPa·s, the liquid crystal dielectric constant Δε is -1.4, the liquid crystal cell thickness d is 3.2 μm, and the liquid crystal elastic coefficient K... 22 At a Pa of 11.2, the initial duration t on The duration is 14.5ms, and the end time is t. off It takes 16.9ms.

[0053] In one example, when the first voltage signal is 17V and the second voltage signal is 1V, the driving voltage Vop ranges from 0 to 16V. The liquid crystal viscosity γ1 is 61 mPa·s, the liquid crystal dielectric constant Δε is -1.3, the liquid crystal cell thickness d is 3.1 μm, and the liquid crystal elastic coefficient K... 22 At a Pa of 10.6, the initial duration t on The duration is 10.875ms, and the duration at the end is t. off It takes 12.675ms.

[0054] The embodiments of this application connect the pixel circuits and Vcom lines in the liquid crystal display substrate by adding vias, which does not affect the aperture ratio of the liquid crystal display product. The Dual Vcom driving method does not require changing the COF (Chip On FPC) output voltage of the liquid crystal display substrate, and does not increase the power consumption of the liquid crystal display product.

[0055] Implementation Method 2: Implementation Method 2 of this application is a Dual Vcom + Column Inversion + Column architecture. Dual Vcom indicates that the liquid crystal display substrate in this application is configured with two types of Vcom lines: a first type of voltage line and a second type of voltage line. These two types of Vcom lines provide voltage signals with different voltage values, and the voltage values ​​are interchanged in different periods (odd and even periods). The Column Inversion + Column architecture means that the polarity of each pixel circuit in the same pixel column is the same, and the polarity of the same pixel column is the same in the same frame, while the polarity of the same pixel column is opposite in two adjacent frames.

[0056] In this embodiment, the liquid crystal display substrate includes a pixel array, first type voltage lines, and second type voltage lines. The pixel array includes multiple pixels, which are divided into first type pixels and second type pixels. Each first type voltage line corresponds to a pixel row, and each second type voltage line corresponds to a pixel row. Each first type voltage line connects to each first type pixel in its corresponding pixel row, and each second type voltage line connects to each second type pixel in its corresponding pixel row. First type pixels and second type pixels are arranged alternately in the same pixel row, and pixels of the same type are in the same pixel column. The structures of first type pixels and second type pixels can be the same, but when displaying the same frame, the polarities of the first type pixels and second type pixels are opposite.

[0057] See Figure 7 ,exist Figure 7 In this diagram, Vcom E represents a first-class voltage line, and Vcom O represents a second-class voltage line. First-class voltage lines include Vcom E1, Vcom E2, Vcom E3…Vcom Ei…Vcom En, where Vcom Ei represents the i-th first-class voltage line. Second-class voltage lines include Vcom O1, Vcom O2, Vcom O3…Vcom Oi…Vcom On, where Vcom Oi represents the i-th second-class voltage line. "+" pixels are positive pixels corresponding to first-class pixels, and "-" pixels are negative pixels corresponding to second-class pixels. Figure 7 The diagram shows the vertically arranged data lines, the horizontally arranged grid lines, and the different pixels defined by their intersection. Each row of pixels corresponds to one Vcom O and one Vcom E, for example, see [link to example]. Figure 7In the first row of pixels, each second-type pixel is connected to Vcom O1, and each first-type pixel is connected to Vcom E1. In the second row of pixels, each second-type pixel is connected to Vcom O2, and each first-type pixel is connected to Vcom E2. Two buses, Vcom E and Vcom O, are set in the non-display area of ​​the liquid crystal display substrate. Each Vcom E in the display area needs to be connected to the Vcom E bus in the non-display area, and each Vcom O in the display area needs to be connected to the Vcom O bus in the non-display area. These buses can be located in the non-display area to the left or right of the display area. Figure 7 The method of setting the bus in the non-display area to the left of the display area is only an example. The method of setting the bus in other non-display areas is within the protection scope of this application.

[0058] A via is placed at any pixel of the first type of pixels in a pixel row to connect the Vcom E of two adjacent rows. A via is placed at any pixel of the second type of pixels in a pixel row to connect the Vcom O of two adjacent rows. See [link to documentation]. Figure 7 The i-th Vcom E is connected to the Vcom voltage terminal of the first type of pixel in the (i+1)-th row through a via. Since the (i+1)-th Vcom E is connected to the Vcom voltage terminal of the first type of pixel in the (i+1)-th row, the connection between the i-th Vcom E and the (i+1)-th Vcom E is achieved. The j-th Vcom O is connected to the Vcom voltage terminal of the second type of pixel in the (j-1)-th row through a via. Since the (j-1)-th Vcom O is connected to the Vcom voltage terminal of the second type of pixel in the (j-1)-th row, the connection between the j-th Vcom O and the (j-1)-th Vcom O is achieved.

[0059] Specifically, Vcom O connects to each second-type pixel in its corresponding pixel row. For example, for the i-th Vcom O, the i-th Vcom O connects to each second-type pixel in the i-th pixel row, specifically by connecting to the Vcom voltage terminal of the second-type pixel. The Vcom voltage terminal of a second-type pixel in the i-th pixel row is connected to the (i+1)-th Vcom O through a via to reduce the voltage difference between each Vcom O. Vcom E connects to each first-type pixel in its corresponding pixel row. For example, for the i-th Vcom E, the i-th Vcom E connects to each first-type pixel in the i-th pixel row, specifically by connecting to the Vcom voltage terminal of the first-type pixel. The Vcom voltage terminal of a first-type pixel in the (i+1)-th pixel row is connected to the i-th Vcom E through a via to reduce the voltage difference between each Vcom E.

[0060] In the embodiments of this application, vias in the display area are used to connect pixel circuits of the same type or Vcom lines corresponding to pixel circuits of the same type in different pixel rows together, so that all Vcom O in the liquid crystal display substrate are connected together and all Vcom E are connected together, thereby enhancing the uniformity of Vcom in the substrate. It is understood that only one first-type pixel or second-type pixel needs to be punched in each pixel row, and the first-type and second-type pixels to be punched can be selected according to actual conditions. Therefore, there are multiple options for the location of the vias, all of which are within the scope of protection of this application.

[0061] In the embodiments of this application, the Vcom line in the non-display area is the same as in Embodiment 1. The difference is that an additional Vcom line needs to be added between adjacent different rows of pixels in the display area of ​​the liquid crystal display substrate. That is, in Embodiment 1, there is one Vcom line between different rows of pixels, and in Embodiment 2, there are two Vcom lines between different rows of pixels.

[0062] During the Vcom voltage reversal process between two adjacent frames, the polarity of the pixel circuit also reverses, see [link / reference]. Figure 6 In the current frame, the first column is always positive. After the Vcom voltage reverses, the first column in the next frame reverses to negative. Similarly, in the current frame, the second column is always negative. After the Vcom voltage reverses, the second column in the next frame reverses to positive. During the Vcom voltage reversal process between adjacent frames, the difference between the Source voltage and the Vcom voltage is displayed in different grayscale levels between 0 and 255. See [link / reference]. Figure 5 In frame N, the Vcom voltage is 18V, and the Source voltage ranges from 0.2V to 17.2V. When the Source voltage is 0.2V, the voltage difference is -17.8V, and the corresponding grayscale is 255. Since the Source voltage is lower than the Vcom voltage, it is negative when it is below the Vcom voltage. When the Source voltage is 17.2V, the voltage difference is -0.8V, and the corresponding grayscale is 0. Since the Source voltage is lower than the Vcom voltage, it is negative when it is below the Vcom voltage. In frame N+1, the Vcom voltage is 0V, and the Source voltage ranges from 0.2V to 17.2V. When the Source voltage is 0.2V, the voltage difference is 0.2V, and the corresponding grayscale is 0. Since the Source voltage is higher than the Vcom voltage, it is positive when it is above the Vcom voltage. When the Source voltage is 17.2V, the voltage difference is 17V, and the corresponding grayscale is 255. Since the Source voltage is higher than the Vcom voltage, it is positive when it is above the Vcom voltage.

[0063] In the embodiments of this application, the liquid crystal display panel is configured with two types of Vcom lines, each providing a voltage signal with a different voltage value. In this embodiment, the first voltage signal ranges from 16-18V; for example, the first voltage signal can be 16V, 16.5V, 17V, 18V, or any value in between. The second voltage signal ranges from 0-2V; for example, the second voltage signal can be 0V, 0.5V, 1V, 2V, or any value in between. The driving voltage Vop of the liquid crystal display substrate can be increased to 0-16V; for example, the driving voltage Vop can be 0V, 2V, 3V, 6V, 16V, or any value in between. By increasing the driving voltage Vop of the liquid crystal display substrate, the limits of liquid crystal design can be further expanded. The range of various parameters of the liquid crystal display panel can be adjusted as follows: the liquid crystal viscosity γ1 in the liquid crystal display substrate ranges from 55 mPa·s to 67 mPa·s. For example, the liquid crystal viscosity γ1 can be 55 mPa·s, 57 mPa·s, 59 mPa·s, 61 mPa·s, 67 mPa·s, or any value between these values. The liquid crystal dielectric constant Δε ranges from -1.2 to -1.4. For example, the liquid crystal dielectric constant Δε can be -1.2, -1.25, -1.35, -1.4, or any value between these values. The liquid crystal cell thickness d ranges from 3.0 μm to 3.2 μm. For example, the liquid crystal cell thickness d can be 3.0 μm, 3.05 μm, 3.1 μm, 3.15 μm, 3.2 μm, or any value between these values. The liquid crystal elastic coefficient K... 22 The value range is 10 Pa to 11.2 Pa (Pascals), for example, the elastic coefficient K of liquid crystal. 22 The value can be 10 Pa, 10.5 Pa, 10.7 Pa, 11.2 Pa, or any value in between. This allows the response time range of the LCD panel to be adjusted as follows: start duration t on The range is 7.25ms-14.5ms, for example, the start duration t. on The duration can be: 7.25ms, 8.5ms, 10.5ms, 12.5ms, 14.5ms, or any value in between, with a final duration t. off The range is 8.45ms-16.9ms, for example, the duration t at the end. off The response time can be 8.45ms, 9.5ms, 12.5ms, 14.5ms, 16.9ms, or any value in between. This achieves the goal of shortening the response time of the LCD panel.

[0064] In one example, when the first voltage signal is 16V and the second voltage signal is 0V, the driving voltage Vop ranges from 0 to 16V. The liquid crystal viscosity γ1 is 55 mPa·s, the liquid crystal dielectric constant Δε is -1.2, the liquid crystal cell thickness d is 3.0 μm, and the liquid crystal elastic coefficient K... 22 When the Pa is 10, the initial duration t on It lasts for 7.25ms, and the duration at the end is t. off The response time is 8.45ms. At this value, the response time of the LCD panel is relatively short, thus achieving the goal of reducing the overall response time of the LCD panel.

[0065] In one example, when the first voltage signal is 18V and the second voltage signal is 2V, the driving voltage Vop ranges from 0 to 16V. The liquid crystal viscosity γ1 is 67 mPa·s, the liquid crystal dielectric constant Δε is -1.4, the liquid crystal cell thickness d is 3.2 μm, and the liquid crystal elastic coefficient K... 22 At a Pa of 11.2, the initial duration t on The duration is 14.5ms, and the end time is t. off It takes 16.9ms.

[0066] In one example, when the first voltage signal is 17V and the second voltage signal is 1V, the driving voltage Vop ranges from 0 to 16V. The liquid crystal viscosity γ1 is 61 mPa·s, the liquid crystal dielectric constant Δε is -1.3, the liquid crystal cell thickness d is 3.1 μm, and the liquid crystal elastic coefficient K... 22 At a Pa of 10.6, the initial duration t on The duration is 10.875ms, and the duration at the end is t. off It takes 12.675ms.

[0067] The implementation method of this application ensures that all Vcom O lines and all Vcom E lines in the substrate are connected together by adding a small number of vias, thus guaranteeing the uniformity of Vcom lines on the substrate. The location of the vias can be selected according to the actual layer structure of the substrate. The selected location of the vias should not affect the layout of other circuits. However, adding Vcom lines will affect the aperture ratio of the liquid crystal display product. The Dual Vcom driving method does not require changing the COF (ChipOn FPC, chip fixed on flexible circuit board) output voltage of the liquid crystal display substrate, and will not increase the power consumption of the liquid crystal display product.

[0068] Implementation Method 3: Implementation Method 3 of this application adopts a Dual Vcom + Column Inversion + Z-architecture. Dual Vcom indicates that the liquid crystal display substrate in this application is configured with two types of Vcom lines: a first type of voltage line and a second type of voltage line. These two types of Vcom lines provide voltage signals with different voltage values, and the voltage values ​​are interchanged in different periods (odd and even periods). Column inversion refers to the reversal of pixel polarity in each pixel column between two adjacent frames. The Z-architecture refers to the alternating arrangement of first and second type pixels in the same pixel column and in the same pixel row, with the same type of pixels arranged in a "Z" shape, hence the name Z-architecture. A schematic diagram of the column inversion + Z-architecture can be seen as follows... Figure 9 As shown, the polarity of each pixel in two adjacent frames is reversed, and the arrangement of pixels with the same polarity in the same frame presents a "Z" shape.

[0069] In this embodiment, the liquid crystal display substrate includes a pixel array, first type voltage lines, and second type voltage lines. The pixel array includes multiple pixels, which are divided into first type pixels and second type pixels. Each first type voltage line corresponds to one pixel row, and each second type voltage line corresponds to one pixel row. Each first type voltage line connects to each first type pixel in its corresponding pixel row, and each second type voltage line connects to each second type pixel in its corresponding pixel row. First type pixels and second type pixels are arranged alternately in the same pixel row and in the same pixel column, forming a "Z" shape in the pixel array for the same type of pixel arrangement. The structures of the first type pixels and second type pixels can be the same, but when displaying the same frame, the polarities of the first type pixels and second type pixels are opposite.

[0070] See Figure 8 In this diagram, VcomE represents a Type I voltage line, and VcomO represents a Type II voltage line. "+" pixels are positive pixels corresponding to Type I pixels, and "-" pixels are negative pixels corresponding to Type II pixels. Figure 4 The diagram illustrates the vertically arranged data lines, the horizontally arranged grid lines, and the intersections that define different pixels. Each pixel row corresponds to one Vcom O and one Vcom E; one Vcom O corresponds to one pixel row, and one Vcom E corresponds to one pixel row. For example, see [link to example diagram]. Figure 8In the first row of pixels, each second-type pixel is connected to Vcom O1, and each first-type pixel is connected to Vcom E1. In the second row of pixels, each second-type pixel is connected to Vcom O2, and each first-type pixel is connected to Vcom E2. Two buses, Vcom E and Vcom O, are set in the non-display area of ​​the liquid crystal display substrate. Each Vcom E in the display area needs to be connected to the Vcom E bus in the non-display area, and each Vcom O in the display area needs to be connected to the Vcom O bus in the non-display area. These buses can be located in the non-display area to the left or right of the display area. Figure 8 The method of setting the bus in the non-display area to the left of the display area is only an example. The method of setting the bus in other non-display areas is within the protection scope of this application.

[0071] The display area includes vias used to connect Vcom E of two adjacent rows and Vcom O of two adjacent rows. See [link to documentation]. Figure 8 The i-th Vcom E is connected to the Vcom voltage terminal of the first type of pixel in the (i+1)-th row through a via. Since the (i+1)-th Vcom E is connected to the Vcom voltage terminal of the first type of pixel in the (i+1)-th row, the connection between the i-th Vcom E and the (i+1)-th Vcom E is achieved. The j-th Vcom O is connected to the Vcom voltage terminal of the second type of pixel in the (j-1)-th row through a via. Since the (j-1)-th Vcom O is connected to the Vcom voltage terminal of the second type of pixel in the (j-1)-th row, the connection between the j-th Vcom O and the (j-1)-th Vcom O is achieved.

[0072] Specifically, Vcom O connects to each second-type pixel in its corresponding pixel row. For example, for the i-th Vcom O, the i-th Vcom O connects to each second-type pixel in the i-th pixel row, specifically by connecting to the Vcom voltage terminal of the second-type pixel. The Vcom voltage terminal of a second-type pixel in the i-th pixel row is connected to the (i+1)-th Vcom O through a via to reduce the voltage difference between each Vcom O. Vcom E connects to each first-type pixel in its corresponding pixel row. For example, for the i-th Vcom E, the i-th Vcom E connects to each first-type pixel in the i-th pixel row, specifically by connecting to the Vcom voltage terminal of the first-type pixel. The Vcom voltage terminal of a first-type pixel in the (i+1)-th pixel row is connected to the i-th Vcom E through a via to reduce the voltage difference between each Vcom E.

[0073] In the embodiments of this application, vias in the display area are used to connect pixel circuits of the same type or Vcom lines corresponding to pixel circuits of the same type in different pixel rows together, so that all Vcom O in the liquid crystal display substrate are connected together and all Vcom E are connected together, thereby enhancing the uniformity of Vcom in the substrate. It is understood that only one first-type pixel or second-type pixel needs to be punched in each pixel row, and the first-type and second-type pixels to be punched can be selected according to actual conditions. Therefore, there are multiple options for the location of the vias, all of which are within the scope of protection of this application.

[0074] In the embodiments of this application, the Vcom lines in the non-display area are the same as in Embodiment 1, and the Vcom lines in the display area are the same as in Embodiment 2. The difference is that Embodiment 3 uses a Z-architecture, while Embodiments 1 and 2 use a Column-architecture.

[0075] During the Vcom voltage reversal process between two adjacent frames, the polarity of the pixel circuit also reverses, see [link / reference]. Figure 9 In the current frame, the first column's polarity is positive-negative-positive. After the Vcom voltage reverses, the first column in the next frame also reverses, becoming negative-positive-negative. Similarly, in the current frame, the second column's polarity is negative-positive-negative. After the Vcom voltage reverses, the second column in the next frame also reverses, becoming positive-negative-positive. During the Vcom voltage reversal process between adjacent frames, the difference between the Source voltage and the Vcom voltage is displayed in different grayscale levels between 0 and 255. See [link / reference]. Figure 5 In frame N, the Vcom voltage is 18V, and the Source voltage ranges from 0.2V to 17.2V. When the Source voltage is 0.2V, the voltage difference is -17.8V, and the corresponding grayscale is 255. Since the Source voltage is lower than the Vcom voltage, it is negative when it is below the Vcom voltage. When the Source voltage is 17.2V, the voltage difference is -0.8V, and the corresponding grayscale is 0. Since the Source voltage is lower than the Vcom voltage, it is negative when it is below the Vcom voltage. In frame N+1, the Vcom voltage is 0V, and the Source voltage ranges from 0.2V to 17.2V. When the Source voltage is 0.2V, the voltage difference is 0.2V, and the corresponding grayscale is 0. Since the Source voltage is higher than the Vcom voltage, it is positive when it is above the Vcom voltage. When the Source voltage is 17.2V, the voltage difference is 17V, and the corresponding grayscale is 255. Since the Source voltage is higher than the Vcom voltage, it is positive when it is above the Vcom voltage.

[0076] The image quality of the Column architecture and the Z architecture will differ to some extent under the same monochrome or heavy-load screen. In the actual product design process, the choice of architecture will be based on the user's requirements for the product.

[0077] In the embodiments of this application, the liquid crystal display panel is configured with two types of Vcom lines, each providing a voltage signal with a different voltage value. In this embodiment, the first voltage signal ranges from 16-18V; for example, the first voltage signal can be 16V, 16.5V, 17V, 18V, or any value in between. The second voltage signal ranges from 0-2V; for example, the second voltage signal can be 0V, 0.5V, 1V, 2V, or any value in between. The driving voltage Vop of the liquid crystal display substrate can be increased to 0-16V; for example, the driving voltage Vop can be 0V, 2V, 3V, 6V, 16V, or any value in between. By increasing the driving voltage Vop of the liquid crystal display substrate, the limits of liquid crystal design can be further expanded. The range of various parameters of the liquid crystal display panel can be adjusted as follows: the liquid crystal viscosity γ1 in the liquid crystal display substrate ranges from 55 mPa·s to 67 mPa·s. For example, the liquid crystal viscosity γ1 can be 55 mPa·s, 57 mPa·s, 59 mPa·s, 61 mPa·s, 67 mPa·s, or any value between these values. The liquid crystal dielectric constant Δε ranges from -1.2 to -1.4. For example, the liquid crystal dielectric constant Δε can be -1.2, -1.25, -1.35, -1.4, or any value between these values. The liquid crystal cell thickness d ranges from 3.0 μm to 3.2 μm. For example, the liquid crystal cell thickness d can be 3.0 μm, 3.05 μm, 3.1 μm, 3.15 μm, 3.2 μm, or any value between these values. The liquid crystal elastic coefficient K... 22 The value range is 10 Pa to 11.2 Pa (Pascals), for example, the elastic coefficient K of liquid crystal. 22 The value can be 10 Pa, 10.5 Pa, 10.7 Pa, 11.2 Pa, or any value in between. This allows the response time range of the LCD panel to be adjusted as follows: start duration t on The range is 7.25ms-14.5ms, for example, the start duration t. on The duration can be: 7.25ms, 8.5ms, 10.5ms, 12.5ms, 14.5ms, or any value in between, with a final duration t. off The range is 8.45ms-16.9ms, for example, the duration t at the end. off The response time can be 8.45ms, 9.5ms, 12.5ms, 14.5ms, 16.9ms, or any value in between. This achieves the goal of shortening the response time of the LCD panel.

[0078] In one example, when the first voltage signal is 16V and the second voltage signal is 0V, the driving voltage Vop ranges from 0 to 16V. The liquid crystal viscosity γ1 is 55 mPa·s, the liquid crystal dielectric constant Δε is -1.2, the liquid crystal cell thickness d is 3.0 μm, and the liquid crystal elastic coefficient K... 22 When the Pa is 10, the initial duration t on It lasts for 7.25ms, and the duration at the end is t. off The response time is 8.45ms. At this value, the response time of the LCD panel is relatively short, thus achieving the goal of reducing the overall response time of the LCD panel.

[0079] In one example, when the first voltage signal is 18V and the second voltage signal is 2V, the driving voltage Vop ranges from 0 to 16V. The liquid crystal viscosity γ1 is 67 mPa·s, the liquid crystal dielectric constant Δε is -1.4, the liquid crystal cell thickness d is 3.2 μm, and the liquid crystal elastic coefficient K... 22 At a Pa of 11.2, the initial duration t on The duration is 14.5ms, and the end time is t. off It takes 16.9ms.

[0080] In one example, when the first voltage signal is 17V and the second voltage signal is 1V, the driving voltage Vop ranges from 0 to 16V. The liquid crystal viscosity γ1 is 61 mPa·s, the liquid crystal dielectric constant Δε is -1.3, the liquid crystal cell thickness d is 3.1 μm, and the liquid crystal elastic coefficient K... 22 At a Pa of 10.6, the initial duration t on The duration is 10.875ms, and the duration at the end is t. off It takes 12.675ms.
