Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to an array substrate and a 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 peripheral driving circuitry, the image is displayed. Dual-gate LCD architecture is a commonly used architecture because it reduces the number of data lines and increases the aperture ratio.

For example... Figures 1 to 3 As shown, for LCD products with a dual-gate architecture in the prior art, when the two-dot inversion occurs, the data signal needs to be inverted once every two scan lines. However, the switching frequency of the data signal is too fast, the driving power consumption is large, and the display quality of the two-dot inversion is poor. Figure 4 This is a waveform diagram of the scan signal and data signal during single-point inversion in existing technology 1; Figure 5 It corresponds to existing technology 1 Figure 4 A schematic diagram of the polarity of the array substrate during single-point reversal. (See diagram below.) Figure 4 and Figure 5 As shown, in the existing technology, when performing single-point reversal, the data signal needs to be reversed once for each scan line. Although it can achieve a single-point reversal effect with good image quality, the data signal switching frequency is faster and the driving power consumption is greater.

For example... Figures 6 to 8 As shown, in order to reduce the driving power consumption during dual-point inversion, the existing technology 2 adopts another dual-gate architecture LCD product with "Z"-shaped routing for the data lines. During dual-point inversion, the data signal only needs to switch once per frame. Although this can save power consumption, the "Z"-shaped routing increases the routing length and parasitic capacitance, resulting in a larger data signal loading delay. This architecture has more invalid pixels at the edges and a larger bezel. Moreover, for in-cell touch LCD products, it will also increase the loading delay of the touch signal. Figure 9 This is a schematic diagram of the waveforms of the scanning signal and the data signal during single-point inversion in the prior art 2; Figure 10 It corresponds to existing technology two Figure 9 A schematic diagram of the polarity of the array substrate during single-point reversal. (See diagram below.) Figure 9 and Figure 10 As shown, in order to achieve better single-point reversal, the data signal also needs to be reversed once for each scan line. Although it can achieve a better single-point reversal effect, the switching frequency of the data signal is too fast, and the driving power consumption will also increase. Summary of the Invention

[0046] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the specific implementation methods, structures, features, and effects of the array substrate and display device proposed according to the present invention are described in detail below with reference to the accompanying drawings and preferred embodiments:

[0047] [Example 1]

[0048] Figure 11 This is a schematic diagram of the polarity of the array substrate during single-point reversal in Embodiment 1 of the present invention. Figure 11As shown in Embodiment 1 of the present invention, an array substrate is provided, which has multiple scan lines, multiple data lines, multiple pixel units P arranged in an array, and multiple repeating units. Each repeating unit includes two rows and three columns of pixel units P, i.e., six pixel units P.

[0049] Two adjacent scan lines are designated as first scan line 11 and second scan line 12. First scan line 11 and second scan line 12 are arranged alternately in the column direction. Each row of pixel units P has first scan line 11 and second scan line 12 corresponding to its upper and lower sides, and adjacent rows of pixel units P are connected by first scan line 11 and second scan line 12. In this embodiment, the first scan line 11 corresponding to each row of pixel units P is located above that row, and the second scan line 12 corresponding to each row is located below that row. Each pixel unit P in each row is electrically connected to its corresponding first scan line 11 and second scan line 12, with one scan line per pixel unit P. For example, the (2N-1)th scan line is the first scan line 11, and the 2Nth scan line is the second scan line 12, where N is an integer greater than or equal to 1. Of course, in other embodiments, the first scan line 11 corresponding to each row of pixel units P may also be located below that row, and the second scan line 12 corresponding to each row may be located above that row.

[0050] Two adjacent data lines are designated as first data line 21 and second data line 22. The first data line 21 and second data line 22 are arranged alternately in the row direction. Each column of repeating units has a first data line 21 and a second data line 22 on both its left and right sides. Adjacent columns of repeating units also have a first data line 21 and a second data line 22 between them. Within the same repeating unit, no data line is needed between adjacent pixel units P. In this embodiment, the first data line 21 corresponding to each column of repeating units is located on the left side of that column, and the second data line 22 corresponding to each column is located on the right side of that column. Each pixel unit P in each column of repeating units is electrically connected to its corresponding first data line 21 and second data line 22, with one data line per pixel unit P. For example, the 2N-1th data line is the first data line 21, and the 2Nth data line is the second data line 22, where N is an integer greater than or equal to 1. Of course, in other embodiments, the first data line 21 corresponding to each column of repeating units may also be located on the right side of that column, and the second data line 22 corresponding to each column may be located on the left side of that column. In order to enable different pixel units P to be controlled independently, no two pixel units P can be connected to the same scan line or the same data line.

[0051] In each repeating unit, the pixel units P in the first and third columns of one row are electrically connected to the first data line 21, and the pixel units P in the second column are electrically connected to the second data line 22; in the other row, the pixel units P in the first and third columns are electrically connected to the second data line 22, and the pixel units P in the second column are electrically connected to the first data line 21.

[0052] In this embodiment, the repeating unit includes a first repeating unit C1 and a second repeating unit C2.

[0053] Optionally, a column of first repeating units C1 and a column of second repeating units C2 are arranged alternately in the row direction, so that all first data lines 21 are applied with electrical signals of the same polarity at the same time, all second data lines 22 are applied with electrical signals of the same polarity at the same time, and the polarities of the first data lines 21 and the second data lines 22 are opposite at the same time.

[0056] Further, in each repeating unit, the pixel units P in the first and third columns of a row are electrically connected to the second data line 22, and the pixel units P in the second column are electrically connected to the first data line 21. In this row, the pixel units P in the second and third columns are electrically connected to the first scan line 11, and the pixel units P in the first column are electrically connected to the second scan line 12; or, in this row, the pixel units P in the second and third columns are electrically connected to the second scan line 12, and the pixel units P in the first column are electrically connected to the first scan line 11.

[0060] Figure 13 This is a schematic diagram of the data signal waveform during single-point inversion in Embodiment 1 of the present invention. For example... Figure 13 As shown, the driving method of the array substrate during single-point inversion in this embodiment is as follows:

[0061] A first data signal is applied to one of the first data lines 21 and the second data lines 22 corresponding to each column of repeating units, while a second data signal is applied to the other. The polarities of the first and second data signals are opposite at the same time. In this embodiment, the first data signal is applied to all first data lines 21, and the second data signal is applied to all second data lines 22. For example, the first data signal is applied to the 2N-1th data line, and the second data signal is applied to the 2Nth data line, where N is an integer greater than or equal to 1. Both the first and second data signals are inverted once per frame, thereby achieving single-point inversion, which improves display quality while reducing driving power consumption.

[0063] Figure 14 This is a schematic diagram of the polarity of the array substrate during single-point reversal in Embodiment 2 of the present invention. Figure 15 This is a schematic diagram of the planar structure of the touch traces and touch electrode block in Embodiment 2 of the present invention. Figure 14 and Figure 15 As shown, the array substrate provided in Embodiment 2 of the present invention is similar to that in Embodiment 1. Figures 11 to 13 The array substrates in this embodiment are basically the same, except that in this embodiment:

[0064] The array substrate has multiple touch traces 23 and multiple touch electrode blocks 24. The touch traces 23 and data lines are arranged alternately and parallel to each other. Each touch electrode block 24 is electrically connected to a corresponding touch trace 23, and any two touch electrode blocks 24 are connected to different touch traces 23. The touch electrode blocks 24 can be common electrodes, meaning they can be used to apply both touch signals and common signals, thus achieving in-cell touch mode. The touch traces 23 and data lines can be located on the same layer and etched from the same metal film. The touch electrode blocks 24 are electrically connected to the corresponding touch traces 23 through contact holes. Since the data lines do not need to use a "Z"-shaped routing, the touch traces 23 also do not need to use a "Z"-shaped routing, which not only improves the aperture ratio but also avoids the problem of large loading of data signals and touch signals.

[0071] like Figure 17 As shown, the driving method of the array substrate during single-point inversion in this embodiment is as follows:

[0072] A first data signal is applied to one of the first data line 21 and the second data line 22 corresponding to each column of repeating units, while a second data signal is applied to the other.

[0079] refer to Figure 17 As shown, the driving method of the array substrate during single-point inversion in this embodiment is as follows:

[0080] A first data signal is applied to one of the first data line 21 and the second data line 22 corresponding to each column of repeating units, while a second data signal is applied to the other. The polarities of the first and second data signals are opposite at the same time.

Both the first and second data signals are inverted once per frame, thereby achieving single-point inversion, which improves display quality while reducing driving power consumption.

[0081] Those skilled in the art should understand that the remaining structure and working principle of this embodiment are the same as those of Embodiment 3, and will not be repeated here.

[0082] Figure 19 This is a schematic diagram of the display device in the black state in this invention. Figure 20 This is a schematic diagram of the display device in the white state according to the present invention. Figures 19 to 20 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.

[0083] 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. The backlight module 40 includes a backlight source 41 and a privacy layer 43, which is used to reduce the range of light emission angle. A brightness enhancement film 42 is also provided between the backlight source 41 and the privacy layer 43 to increase the brightness of the backlight module 40. The privacy layer 43 is essentially a miniature venetian blind structure, which can block light with a large incident angle and allow light with a small incident angle to pass through, thus reducing the angle range of light passing through the privacy layer 43. The privacy layer 43 includes multiple parallel light-blocking walls and light-transmitting holes located between two adjacent light-blocking walls, and light-absorbing materials are provided on both sides of the light-blocking walls. Of course, the backlight 41 can also be a light-concentrating backlight, thus eliminating the need for a privacy screen 43, but light-concentrating backlights are more expensive than conventional backlights.

[0084] like Figures 19 to 20As shown, this application also provides a display panel 30 for use in the display device described above. The display panel 30 includes a color filter substrate 31 and an array substrate 32 as described above. The color filter substrate 31 and the array substrate 32 are disposed opposite to each other, and a liquid crystal layer 33 is 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, and 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 may also use negative liquid crystal molecules, and the negative liquid crystal molecules in the liquid crystal layer 33 may 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.

[0085] The color filter substrate 31 has an array of color resist layers 312 and black matrices 311 separating the color resist layers 312. The color resist layers 312 include red (R), green (G), and blue (B) color resist materials, and correspondingly form red (R), green (G), and blue (B) pixel units P, that is, multiple pixel units P have red sub-pixels R, green sub-pixels G, and blue sub-pixels B. Among them, a column of red sub-pixels R, a column of green sub-pixels G, and a column of blue sub-pixels B are arranged periodically in the row direction. Each repeating unit includes a column of red sub-pixels R, a column of green sub-pixels G, and a column of blue sub-pixels B. Of course, in other embodiments, the R / G / B pixels can also adopt other arrangements.

[0086] In this embodiment, a common electrode 321 is also provided on the side of the array substrate 32 facing the liquid crystal layer 33. The common electrode 321 and the pixel electrode 322 are located on different layers and are insulated from each other by an insulating layer. The common electrode 321 may be located above or below the pixel electrode 322. Figure 19The diagram shows the common electrode 321 located below the pixel electrode 322. Preferably, the common electrode 321 is a planar electrode disposed across the entire surface, and the pixel electrode 322 is a block electrode disposed within each pixel unit or a slit electrode with multiple electrode strips, to form a fringe field switching (FFS) mode. Of course, in other embodiments, the pixel electrode 322 and the common electrode 321 may be located on the same layer, but they are insulated from each other. 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.

[0087] In another embodiment, when the array substrate 32 adopts an in-cell touch mode, the touch electrode block 24 can be a common electrode 321, therefore, there is no need to separately set the common electrode 321. (See reference) Figure 15 The array substrate has multiple touch traces 23 and multiple touch electrode blocks 24. The touch traces 23 and data lines are arranged alternately and parallel to each other. Each touch electrode block 24 is electrically connected to a corresponding touch trace 23, and any two touch electrode blocks 24 are connected to different touch traces 23. The touch electrode blocks 24 can be common electrodes, meaning they can be used to apply both touch signals and common signals, thus achieving in-cell touch mode. The touch traces 23 and data lines can be located on the same layer and etched from the same metal thin film. The touch electrode blocks 24 are electrically connected to the corresponding touch traces 23 through contact holes.

[0088] The color filter substrate 31 and the array substrate 32 can be made of materials such as glass, acrylic, and polycarbonate. The common electrode 321 and the pixel electrode 322 can be made of materials such as indium tin oxide (ITO) or indium zinc oxide (IZO).

[0089] The color filter substrate 31 is provided with an upper polarizer 51, and the array substrate 32 is provided with a lower polarizer 52. The light transmission axes of the upper polarizer 51 and the lower polarizer 52 are perpendicular to each other.
