Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to a pixel structure, display panel, and display device. Background Technology

[0002] With the development of science and technology, LCD (Liquid Crystal Display) monitors have replaced bulky CRT monitors and are increasingly integrated into people's daily lives. In particular, LCD monitors have developed rapidly in recent years due to their small size, light weight, thinness, low power consumption, and no radiation. They occupy a dominant position in the current flat panel display market and are widely used in products of various sizes, covering almost all major electronic products in today's information society, such as LCD TVs, computers, mobile phones, PDAs, GPS, automotive displays, projection displays, cameras, digital cameras, electronic watches, calculators, electronic instruments, meters, public displays, and virtual displays.

[0003] During image display, each liquid crystal pixel in an LCD flat panel display is driven by a thin film transistor (TFT) integrated in a TFT thin film transistor array substrate, and together with the peripheral driving circuit, the image is displayed. Figure 1 This is a planar schematic diagram of the pixel structure in existing technology 1. Figure 2 It corresponds to existing technology 1 Figure 1 A waveform diagram of the scanning signal and data signal, as shown below. Figure 1 and Figure 2 As shown, for the first type of conventional dual-gate LCD product, when the SDRRS (seamless dynamic refresh rate switch) function is enabled, the data signal will switch repeatedly within each frame due to the change in charging time. When the frequency changes, the charging time changes accordingly, and the charging voltage of different sub-pixels is different, resulting in obvious differences in brightness in some parts of the picture. Moreover, the switching frequency of the data signal is too fast, and the driving power consumption is usually relatively large.

[0004] To avoid the problem of obvious differences in brightness when the SDRRS function is enabled, another LCD product with a dual-gate architecture is provided. Figure 3 This is a planar schematic diagram of the pixel structure in the prior art. Figure 4 It corresponds to the second existing technology. Figure 3 A waveform diagram of the scanning signal and data signal, as shown below. Figure 3 and Figure 4As shown, the second type of dual-gate LCD product distributes pixel electrodes of the same polarity in a staggered manner, allowing the same data line to connect to the same polarity pixel electrodes. Therefore, the data signal does not need to switch within each frame; it only needs to switch once per frame. This reduces the switching and amplitude changes of the data signal, resulting in more uniform sub-pixel charging and less noticeable brightness differences when switching drive frequencies. However, this structure still exhibits brightness differences when switching frequencies to display solid-color grayscale images (pure red, pure green, or pure blue), leading to noticeable brightness differences in solid-color grayscale images. Figure 5 This is a planar schematic diagram of the pixel structure when displaying a pure red image in the prior art. Figure 6 It corresponds to existing technology two Figure 5 A waveform diagram of the scanning signal and data signal, as shown below. Figure 5 and Figure 6 As shown, in the second type of dual-gate LCD product displaying pure red, for the pixels connected by the second data line (D2), the fourth sub-pixel in the second row and the first sub-pixel in the third row are charged consecutively. Therefore, the second data line does not need to switch voltage when charging the first sub-pixel in the third row, so there is no data delay. However, after the second data line charges the first sub-pixel in the first row, there are green sub-pixels (the second sub-pixel in the first row) and blue sub-pixels (the third sub-pixel in the second row) in between. Therefore, the second data line needs to switch the positive / negative polarity of the Vcom voltage when charging the fourth sub-pixel in the second row, resulting in a certain data delay. Therefore, the charging time of the two sub-pixels (the fourth sub-pixel in the second row and the first sub-pixel in the third row) is different, resulting in different brightness levels between the two sub-pixels. This leads to a noticeable brightness difference when switching frequencies in a pure grayscale image. Furthermore, the 3N+2 data lines each have multiple consecutively charged sub-pixels, making the brightness difference more pronounced when switching frequencies in a pure grayscale image. Figure 7 This is a planar schematic diagram of the pixel structure when displaying a pure green image in the prior art. Figure 8 It corresponds to existing technology two Figure 7 A schematic diagram of the waveforms of the scanning signal and the data signal. Figure 9 This is a planar schematic diagram of the pixel structure when displaying a pure blue image in the prior art. Figure 10 It corresponds to existing technology two Figure 9 A waveform diagram of the scanning signal and data signal, as shown below. Figures 7 to 10 As shown, similarly, the second type of dual-gate LCD product also has multiple continuously charged sub-pixels when displaying pure green and pure blue images, resulting in a significant difference in brightness when switching frequencies in pure color grayscale images. Summary of the Invention

[0005] In order to overcome the shortcomings and deficiencies of the existing technology, the present invention aims to provide a pixel structure, display panel, and display device to solve the problem that the difference between brightness and darkness is relatively obvious when the dual-gate architecture is enabled and a solid color image is displayed.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] This invention provides a pixel structure comprising multiple scan lines and multiple data lines. The scan lines and data lines are mutually insulated and intersect each other to form multiple pixel units arranged in an array. Each pixel unit includes two sub-pixel units arranged left and right. The two sub-pixel units on the left and right sides of the same pixel unit are respectively a first sub-pixel unit and a second sub-pixel unit. The first sub-pixel unit and the second sub-pixel unit in each pixel unit are respectively connected to two different scan lines and connected to the same data line. Two adjacent pixel units in the same column are respectively connected to two different data lines.

[0008] Two scan lines are provided between two adjacent rows of pixel units. The two adjacent scan lines are a first scan line and a second scan line, respectively. The first scan line and the second scan line are arranged alternately. The first scan line is located above the corresponding row of pixel units, and the second scan line is located below the corresponding row of pixel units. All the first sub-pixel units are connected to the first scan line, and all the second sub-pixel units are connected to the second scan line.

[0009] The sub-pixel unit includes a red sub-pixel unit, a green sub-pixel unit, and a blue sub-pixel unit. For the sub-pixel units connected to the same data line, two sub-pixel units that are adjacent in the charging sequence are different colors.

[0010] Furthermore, the sub-pixel unit also includes a white sub-pixel unit, and a column of red sub-pixel units, a column of green sub-pixel units, a column of blue sub-pixel units, and a column of white sub-pixel units are arranged periodically in sequence.

[0011] Furthermore, the red sub-pixel unit, the green sub-pixel unit, the blue sub-pixel unit, and the white sub-pixel unit have the same aperture ratio;

[0012] Alternatively, the aperture ratios of the red sub-pixel unit, the green sub-pixel unit, and the blue sub-pixel unit may be the same and greater than the aperture ratio of the white sub-pixel unit.

[0013] Furthermore, in the sub-pixel units of row 3N+1, a red sub-pixel unit, a green sub-pixel unit, and a blue sub-pixel unit are arranged periodically in sequence; in the sub-pixel units of row 3N+2, a green sub-pixel unit, a blue sub-pixel unit, and a red sub-pixel unit are arranged periodically in sequence; in the sub-pixel units of row 3N+3, a blue sub-pixel unit, a red sub-pixel unit, and a green sub-pixel unit are arranged periodically in sequence.

[0014] Where N is a positive integer greater than or equal to 0.

[0015] Furthermore, the pixel units in the 2N+1 row are all connected to the data line to their right, and the pixel units in the 2N+2 row are all connected to the data line to their left.

[0016] Where N is a positive integer greater than or equal to 0.

[0017] Furthermore, in the sub-pixel units of the 2N+1 row, a red sub-pixel unit, a green sub-pixel unit, and a blue sub-pixel unit are arranged periodically in sequence; in the sub-pixel units of the 2N+2 row, a green sub-pixel unit, a blue sub-pixel unit, and a red sub-pixel unit are arranged periodically in sequence.

[0018] Where N is a positive integer greater than or equal to 0.

[0019] Furthermore, the pixel units in the 2N+1 row are all connected to the data line to their left, and the pixel units in the 2N+2 row are all connected to the data line to their right.

[0020] Where N is a positive integer greater than or equal to 0.

[0021] Furthermore, in the sub-pixel units of the 2N+1 row, a red sub-pixel unit, a green sub-pixel unit, and a blue sub-pixel unit are arranged periodically in sequence; in the sub-pixel units of the 2N+2 row, a blue sub-pixel unit, a red sub-pixel unit, and a green sub-pixel unit are arranged periodically in sequence.

[0022] Where N is a positive integer greater than or equal to 0.

[0023] This application also provides a display panel, which adopts the pixel structure described above. The display panel includes a color filter substrate and an array substrate disposed opposite to the color filter substrate, and a liquid crystal layer disposed between the color filter substrate and the array substrate. An upper polarizer is disposed on the color filter substrate, and a lower polarizer is disposed on the array substrate. The light transmission axes of the upper polarizer and the lower polarizer are perpendicular to each other.

[0024] This application also provides a display device, including the display panel described above.

[0025] The beneficial effects of this invention are as follows: By connecting the first and second sub-pixel units in each pixel unit to two different scan lines and the same data line respectively, and connecting adjacent pixel units in the same column to two different data lines respectively, all first sub-pixel units are connected to the first scan line above them, and all second sub-pixel units are connected to the second scan line below them. Furthermore, two sub-pixel units with adjacent charging sequences among those connected to the same data line are set to different colors. This application employs this special pixel structure design, enabling SDRRS under double-point inversion to be achieved even when the data signal switches once per frame. Even when displaying a solid color image, there is no significant difference in brightness, improving display quality while reducing driving power consumption. Attached Figure Description

[0048] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following detailed description, in conjunction with the accompanying drawings and preferred embodiments, provides a detailed explanation of the specific implementation methods, structures, features, and effects of the pixel structure, display panel, and display device proposed according to the present invention:

[0049] [Example 1]

[0050] Figure 11 This is one of the planar schematic diagrams of the pixel structure in Embodiment 1 of the invention. Figure 12 This is a second planar schematic diagram of the pixel structure in Embodiment 1 of the invention. For example... Figure 11 and Figure 12 As shown, an embodiment of the present invention provides a pixel structure including multiple scan lines and multiple data lines 2. The scan lines extend in the left-right direction, and the data lines 2 extend in the up-down direction. The multiple scan lines and multiple data lines 2 are mutually insulated and intersect each other, defining multiple pixel units P arranged in an array. Each pixel unit P includes two sub-pixel units arranged left-right. The two sub-pixel units on the left and right sides of the same pixel unit P are respectively the first sub-pixel unit P1 and the second sub-pixel unit P2, that is, the first sub-pixel unit P1 is located to the left of the second sub-pixel unit P2. The first sub-pixel unit P1 and the second sub-pixel unit P2 in each pixel unit P are respectively connected to two different scan lines and connected to the same data line 2. Two adjacent pixel units P in the same column of pixel units P are respectively connected to two different data lines 2.

[0051] Two scan lines are provided between two adjacent rows of pixel units P. These two adjacent scan lines are a first scan line 11 and a second scan line 12, which are arranged alternately. The first scan line 11 is located above the corresponding row of pixel units P, and the second scan line 12 is located below the corresponding row of pixel units P. All first sub-pixel units P1 are connected to the first scan line 11, and all second sub-pixel units P2 are connected to the second scan line 12.

[0052] The sub-pixel unit has a red sub-pixel unit R, a green sub-pixel unit G, and a blue sub-pixel unit B. For sub-pixel units connected to the same data line 2, the two sub-pixel units adjacent in the charging order are different colors, that is, the two sub-pixel units adjacent in the scanning or opening order are different colors.

[0053] In this embodiment, the sub-pixel unit also includes a white sub-pixel unit W, a column of red sub-pixel units R, a column of green sub-pixel units G, a column of blue sub-pixel units B, and a column of white sub-pixel units W arranged periodically. Since the first sub-pixel unit P1 in the same pixel unit P is located to the left of the second sub-pixel unit P2, the first sub-pixel unit P1 has a red sub-pixel unit R and a blue sub-pixel unit B, and the second sub-pixel unit P2 has a green sub-pixel unit G and a white sub-pixel unit W. By adding a white sub-pixel unit W to the sub-pixel unit and arranging it periodically with the red sub-pixel unit R, the green sub-pixel unit G, and the blue sub-pixel unit B, it is possible to achieve that two sub-pixel units adjacent in the charging sequence of the sub-pixel unit connected to the same data line 2 are different colors. Moreover, adding a white sub-pixel unit W can also improve light transmittance, thereby increasing display brightness and reducing power consumption. It can also drive richer color display, which to some extent solves the problems of insufficient brightness and excessive power consumption at high resolution, especially when the mobile phone screen is clear outdoors and has a lot of white background.

[0054] Furthermore, such as Figure 11 As shown, the red sub-pixel unit R, green sub-pixel unit G, blue sub-pixel unit B, and white sub-pixel unit W have the same aperture ratio, thereby improving light transmittance. Figure 12 As shown, the aperture ratios of red sub-pixel units R, green sub-pixel units G, and blue sub-pixel units B can be the same and greater than the aperture ratio of white sub-pixel unit W, thereby improving pixel resolution. Specifically, the aperture ratio of white sub-pixel unit W can be half or one-third of the aperture ratios of red sub-pixel units R, green sub-pixel units G, and blue sub-pixel units B.

[0055] In this embodiment, all pixel units P in the (2N+1)th row of pixel units P are connected to the data line 2 on their right, that is, the first sub-pixel unit P1 and the second sub-pixel unit P2 in the (2N+1)th row of pixel units P are both connected to the data line 2 on their right; all pixel units P in the (2N+2)th row of pixel units P are connected to the data line 2 on their left, that is, the first sub-pixel unit P1 and the second sub-pixel unit P2 in the (2N+2)th row of pixel units P are both connected to the data line 2 on their left. Here, N is a positive integer greater than or equal to 0. Of course, in other embodiments, the pixel units P in the (2N+1)th row of pixel units P can also be connected to the data line 2 on their left, that is, the first sub-pixel unit P1 and the second sub-pixel unit P2 in the (2N+1)th row of pixel units P are both connected to the data line 2 on their left; and all pixel units P in the (2N+2)th row of pixel units P are connected to the data line 2 on their right, that is, the first sub-pixel unit P1 and the second sub-pixel unit P2 in the (2N+2)th row of pixel units P are both connected to the data line 2 on their right.

Figure 14 This corresponds to Embodiment 1 of the Invention Figure 13 A schematic diagram of the waveforms of the scanning signal and the data signal. (See diagram below.) Figure 13 and Figure 14 As shown, in this application, when displaying a pure red image, the pixel structure charges the sub-pixel units in the 4N+1 column, thereby controlling all red sub-pixel units R to be turned on. Specifically, when scanning the 4N+1 scan line, the 2N+2 data line 2 charges the corresponding red sub-pixel unit R; when scanning the 4N+3 scan line, the 2N+1 data line 2 charges the corresponding red sub-pixel unit R, wherein the 2N+1 data line 2 and the 2N+2 data line 2 are applied with electrical signals of opposite polarity.

Figure 16 This corresponds to Embodiment 1 of the Invention Figure 15 A schematic diagram of the waveforms of the scanning signal and the data signal. (See diagram below.) Figure 15 and Figure 16 As shown, in this application, when displaying a pure green image, the pixel structure charges the 4N+2th column of sub-pixel units, thereby controlling all green sub-pixel units G to be turned on. Specifically, when scanning the 4N+2nd scan line, the 2N+2nd data line 2 charges the corresponding green sub-pixel unit G; when scanning the 4N+4th scan line, the 2N+1st data line 2 charges the corresponding green sub-pixel unit G, wherein the 2N+1st data line 2 and the 2N+2nd data line 2 are applied with electrical signals of opposite polarity.

[0058] Figure 17 This is a planar schematic diagram of the pixel structure when displaying a pure blue image in Embodiment 1 of the invention. Figure 18 This corresponds to Embodiment 1 of the Invention Figure 17 A schematic diagram of the waveforms of the scanning signal and the data signal. (See diagram below.) Figure 17 and Figure 18 As shown, in this application, when displaying a pure blue image, the pixel structure charges the 4N+3rd column of sub-pixel units, thereby controlling all blue sub-pixel units B to be turned on. Specifically, when scanning the 4N+1st scan line, the 2N+1st data line 2 charges the corresponding blue sub-pixel unit B; when scanning the 4N+3rd scan line, the 2N+2nd data line 2 charges the corresponding blue sub-pixel unit B, wherein the 2N+1st data line 2 and the 2N+2nd data line 2 are applied with electrical signals of opposite polarity.

[0059] [Example 2]

[0060] Figure 19 This is a planar schematic diagram of the pixel structure in Embodiment 2 of the invention. (See attached diagram.) Figure 19 As shown, the pixel structure provided in Embodiment 2 of the present invention is the same as that in Embodiment 1. Figures 11 to 18 The pixel structure is basically the same as that in this embodiment, except that:

[0061] In the (3N+1)th row of sub-pixel units, a red sub-pixel unit R, a green sub-pixel unit G, and a blue sub-pixel unit B are arranged periodically in sequence; in the (3N+2)th row of sub-pixel units, a green sub-pixel unit G, a blue sub-pixel unit B, and a red sub-pixel unit R are arranged periodically in sequence; in the (3N+3)th row of sub-pixel units, a blue sub-pixel unit B, a red sub-pixel unit R, and a green sub-pixel unit G are arranged periodically in sequence; where N is a positive integer greater than or equal to 0. That is, in the (3N+1)th column of sub-pixel units, a red sub-pixel unit R, a green sub-pixel unit G, and a blue sub-pixel unit B are arranged periodically in sequence; in the (3N+2)th column of sub-pixel units, a green sub-pixel unit G, a blue sub-pixel unit B, and a red sub-pixel unit R are arranged periodically in sequence; in the (3N+3)th column of sub-pixel units, a blue sub-pixel unit B, a red sub-pixel unit R, and a green sub-pixel unit G are arranged periodically in sequence. Since the first sub-pixel unit P1 within the same pixel unit P is located to the left of the second sub-pixel unit P2, both the first sub-pixel unit P1 and the second sub-pixel unit P2 contain a red sub-pixel unit R, a green sub-pixel unit G, and a blue sub-pixel unit B. Thus, through this special color arrangement design of the sub-pixel units, two sub-pixel units connected to the same data line 2 that are adjacent in charging sequence are of different colors. Therefore, in this embodiment, there is no need to add a white sub-pixel unit W to improve the color saturation of the displayed image. Moreover, this special color arrangement design allows the red sub-pixel unit R, the green sub-pixel unit G, and the blue sub-pixel unit B to be distributed more evenly, thereby improving the display quality of the color image.

[0062] Those skilled in the art should understand that the remaining structures and working principles of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

[0063] [Example 3]

[0064] Figure 20 This is one of the planar schematic diagrams of the pixel structure in Embodiment 3 of the invention. Figure 21 This is a second planar schematic diagram of the pixel structure in Embodiment 3 of the invention. For example... Figure 20 and Figure 21As shown, the pixel structure provided in Embodiment 3 of the present invention is the same as that in Embodiment 1. Figures 11 to 18 The pixel structure is basically the same as that in this embodiment, except that:

[0065] like Figure 20 As shown, in the (2N+1)th row of pixel unit P, all pixel units P are connected to the data line 2 on their right, that is, the first sub-pixel unit P1 and the second sub-pixel unit P2 in the (2N+1)th row of pixel unit P are both connected to the data line 2 on their right; in the (2N+2)th row of pixel unit P, all pixel units P are connected to the data line 2 on their left, that is, the first sub-pixel unit P1 and the second sub-pixel unit P2 in the (2N+2)th row of pixel unit P are both connected to the data line 2 on their left. In the (2N+1)th row of sub-pixel units, a red sub-pixel unit R, a green sub-pixel unit G, and a blue sub-pixel unit B are arranged periodically in sequence; in the (2N+2)th row of sub-pixel units, a green sub-pixel unit G, a blue sub-pixel unit B, and a red sub-pixel unit R are arranged periodically in sequence; where N is a positive integer greater than or equal to 0. Specifically, in the 3N+1th column of sub-pixel units, a red sub-pixel unit R and a green sub-pixel unit G are arranged alternately and periodically; in the 3N+2th column of sub-pixel units, a green sub-pixel unit G and a blue sub-pixel unit B are arranged alternately and periodically; and in the 3N+3rd column of sub-pixel units, a blue sub-pixel unit B and a red sub-pixel unit R are arranged alternately and periodically. Thus, through this special color arrangement design of the sub-pixel units, two sub-pixel units adjacent in charging sequence within the sub-pixel units connected to the same data line 2 are each a different color. Therefore, in this embodiment, there is no need to add a white sub-pixel unit W to improve the color saturation of the displayed image. Moreover, this special color arrangement design, where both the first sub-pixel unit P1 and the second sub-pixel unit P2 have a red sub-pixel unit R, a green sub-pixel unit G, and a blue sub-pixel unit B, allows for a more uniform distribution of these elements compared to Embodiment 1, thereby improving the display quality of the color image.

[0066] In another pixel structure, such as Figure 21As shown, in the (2N+1)th row of pixel unit P, all pixel units P are connected to the data line 2 on their left, that is, the first sub-pixel unit P1 and the second sub-pixel unit P2 in the (2N+1)th row of pixel unit P are both connected to the data line 2 on their left; in the (2N+2)th row of pixel unit P, all pixel units P are connected to the data line 2 on their right, that is, the first sub-pixel unit P1 and the second sub-pixel unit P2 in the (2N+2)th row of pixel unit P are both connected to the data line 2 on their right. In the (2N+1)th row of sub-pixel units, a red sub-pixel unit R, a green sub-pixel unit G, and a blue sub-pixel unit B are arranged periodically in sequence; in the (2N+2)th row of sub-pixel units, a blue sub-pixel unit B, a red sub-pixel unit R, and a green sub-pixel unit G are arranged periodically in sequence; where N is a positive integer greater than or equal to 0. Specifically, in the 3N+1th column of sub-pixel units, a red sub-pixel unit R and a blue sub-pixel unit B are arranged alternately and periodically; in the 3N+2nd column of sub-pixel units, a green sub-pixel unit G and a red sub-pixel unit R are arranged alternately and periodically; and in the 3N+3rd column of sub-pixel units, a blue sub-pixel unit B and a green sub-pixel unit G are arranged alternately and periodically. Thus, through this special color arrangement design of the sub-pixel units, two sub-pixel units adjacent in charging sequence within the sub-pixel units connected to the same data line 2 are each a different color. Therefore, in this embodiment, there is no need to add a white sub-pixel unit W to improve the color saturation of the displayed image. Moreover, this special color arrangement design, where both the first sub-pixel unit P1 and the second sub-pixel unit P2 have a red sub-pixel unit R, a green sub-pixel unit G, and a blue sub-pixel unit B, allows for a more uniform distribution of these elements compared to Embodiment 1, thereby improving the display quality of the color image. Of course, in other embodiments, the color arrangement design of the sub-pixel units can be changed according to actual needs, so that two sub-pixel units that are adjacent in charging order in the sub-pixel units connected to the same data line 2 are different colors, which will not be elaborated here.

[0067] Those skilled in the art should understand that the remaining structures and working principles of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

[0068] Figure 22 This is a schematic diagram of the display device in the bright state according to the present invention, as shown below. Figure 22 As shown, the present invention also provides a display device, including a display panel 30 and a backlight module 40, wherein the backlight module 40 is located below the display panel 30 and is used to provide a backlight source for the display panel 30.

[0069] The backlight module 40 can be an edge-lit backlight module or a direct-lit backlight module. Preferably, the backlight module 40 adopts a collimated backlight (CBL) mode, which can collect light and ensure display effect.

[0070] The backlight module 40 includes a backlight source 41 and a privacy layer 43, which reduces the range of light emission angles. A brightness enhancement film 42 is also provided between the backlight source 41 and the privacy layer 43, increasing the brightness of the backlight module 40. The privacy layer 43 acts like a miniature venetian blind, blocking light with a large incident angle while allowing light with a smaller incident angle to pass through, thus reducing the range of light angles passing through the privacy layer 43. The privacy layer 43 includes multiple parallel light-blocking walls and light-transmitting holes located between adjacent light-blocking walls. Light-absorbing material is provided on both sides of the light-blocking walls. Alternatively, the backlight source 41 can be a light-collecting backlight, eliminating the need for a privacy layer 43; however, light-collecting backlights are more expensive than conventional backlights.

[0071] This application also provides a display panel 30 for use in the display device described above. For example... Figure 22 As shown, the display panel 30 adopts the pixel structure described above. The display panel 30 includes a color filter substrate 31, an array substrate 32 disposed opposite to the color filter substrate 31, and a liquid crystal layer 33 disposed between the color filter substrate 31 and the array substrate 32. The liquid crystal layer 33 preferably uses positive liquid crystal molecules, that is, liquid crystal molecules with positive dielectric anisotropy. In the initial state, the positive liquid crystal molecules in the liquid crystal layer 33 are aligned parallel to the color filter substrate 31 and the array substrate 32. The alignment direction of the positive liquid crystal molecules on the side closer to the color filter substrate 31 is parallel or antiparallel to the alignment direction of the positive liquid crystal molecules on the side closer to the array substrate 32. Of course, in other embodiments, the liquid crystal layer 33 can also use negative liquid crystal molecules. The negative liquid crystal molecules in the liquid crystal layer 33 can be aligned perpendicular to the color filter substrate 31 and the array substrate 32, that is, similar to the alignment method of VA display mode.

[0074] When the display panel 30 adopts the pixel structure in Embodiment 2, there is no need to set a white sub-pixel unit W.

Both the pixel electrode 322 and the common electrode 321 may include multiple electrode strips, and the electrode strips of the pixel electrode 322 and the common electrode 321 are arranged alternately to form an in-plane switching (IPS) mode; or, in other embodiments, the array substrate 32 has a pixel electrode 322 on the side facing the liquid crystal layer 33, and the color filter substrate 31 has a common electrode 321 on the side facing the liquid crystal layer 33 to form a TN mode or a VA mode.
