Embodiments for Carrying Out the Invention

[0009] When there are a plurality of display devices mounted on a vehicle, if the display devices can be arranged together in one place so that the display areas are connected, it is considered possible to provide an excellent design, such as displaying an integrated image on a plurality of display areas as needed. For example, if a display device for displaying speed, rotational speed, etc. in Patent Document 1 and a display device that extends from the driver's seat side to the passenger seat side and displays map information, movies, etc. are integrally configured, it is considered possible to provide an excellent interior design and obtain an excellent display effect. On the other hand, when the number of display areas of the display device increases and the area of the entire display area becomes large, the power consumption may also increase. In vehicles that use a motor as a drive source, such as hybrid vehicles and electric vehicles, it is preferable that the power consumption of the display device is small so that the cruising distance can be extended as long as possible. In view of such problems, the present disclosure has conceived a novel display device capable of suppressing power consumption.

[0010] Embodiments of the present disclosure will be described based on the drawings. The present disclosure is not limited to the following embodiments, and design changes can be made as appropriate within the scope that satisfies the configuration of the present disclosure. Also, in the following description, the same reference numerals are commonly used between different drawings for the same parts or parts having similar functions, and repeated descriptions thereof may be omitted. Further, the respective configurations described in the embodiments and modification examples may be appropriately combined or changed without departing from the gist of the present disclosure. For the sake of easy understanding of the description, in the drawings referred to below, the configurations may be shown in a simplified or schematic manner, or some constituent members may be omitted. Also, the dimensional ratios between the constituent members shown in each figure do not necessarily indicate the actual dimensional ratios.

[0011] FIG. 1 is a schematic diagram showing a dashboard 200 of a vehicle equipped with a display device 101 according to the present embodiment. The dashboard 200 is located at the front part of the interior of the vehicle. The display device 101 is disposed from the driver's seat 201 to the passenger seat 202 at the upper part of the dashboard. That is, the display device 101 is located in front of the driver's seat 201 and the passenger seat 202 and is an integrated single device.

[0012] The display device 101 may be various flat displays. For example, the display device 101 may be a liquid crystal display device, an organic EL display device, an LED display device, or an electronic paper or the like. In the present embodiment, the display device 101 is a liquid crystal display device.

[0013] FIG. 2A is a schematic cross-sectional view showing the configuration when the display device 101 is a liquid crystal display device. The display device 101 includes a liquid crystal panel 50 and a control device 90. Further, the liquid crystal panel 50 includes an active matrix substrate 40, a counter substrate 80, and a liquid crystal layer 81.

[0014] The active matrix substrate 40 includes a substrate 10 having a main surface 10a. As will be described in detail below, the main surface 10a has a display area DR and a non-display area NR located around the display area DR so as to surround the display area DR. The display area DR is the area that contributes to image display, and the non-display area is the area where no image is displayed.

[0015] As detailed below, the active matrix substrate 40 includes multiple scan lines, multiple data lines, and multiple pixels. Each pixel is connected to one of the scan lines and one of the data lines.

[0016] The active matrix substrate 40 and the opposing substrate 80 are bonded together with a predetermined gap between them by a seal 82 placed in the non-display area NR, and the liquid crystal layer 81 is located between the active matrix substrate 40 and the opposing substrate 80, within the area surrounded by the seal 82. In this embodiment, a color filter is provided on the surface of the opposing substrate 30 facing the liquid crystal layer 81. However, the color filter may also be provided on the active matrix substrate 40.

[0017] The liquid crystal panel 50 further includes a plurality of scan line driving circuits 60 and a plurality of data line driving circuits 70. The scan line driving circuits 60 and the data line driving circuits 70 are arranged in areas of the substrate 10 other than the display area DR, and drive the scan lines and data lines, respectively. In this embodiment, the scan line driving circuits 60 are arranged in the non-display area NR. On the other hand, the data line driving circuits 70 are arranged on the flexible substrate 51. As shown in Figure 2B, the plurality of data line driving circuits 70 may be mounted in the non-display area NR of the substrate 10.

[0018] The control device 90 includes a circuit board 91 and a timing controller 92 mounted on the circuit board 91. The control device 90 is connected to the active matrix circuit board 40 by a flexible circuit board 51. The timing controller 92 receives video signals from an external host computer and generates scan signals and data signals. The generated scan signals and data signals are output to the scan line drive circuit 60 and the data line drive circuit 70.

[0019] The display device 101 further comprises a pair of polarizing plates 96 and a backlight 95. The pair of polarizing plates 96 are positioned to sandwich the active matrix substrate 40 and the opposing substrate 80. The backlight 95 is positioned opposite one of the pair of polarizing plates 96.

[0020] Figure 3 is a plan view of the substrate 10. The substrate 10 has its longitudinal direction in the x-axis direction (first direction), which is horizontal, rather than in the y-axis direction (second direction), which is vertical. The shape of the substrate 10 is not particularly limited as long as the first direction is longitudinal; for example, it may be rectangular, or it may be an ellipse or oblong. In this embodiment, the substrate 10 is a rectangle with the x-axis direction as its longitudinal direction, and has two rounded upper corners aligned in the x-axis direction.

[0021] As described above, the main surface 10a has a display area DR and a non-display area NR. In this embodiment, the display area DR has a shape that is generally similar to the outer shape of the substrate 10, that is, a rectangle with the x-axis direction as the longitudinal direction, in which the two upper corners aligned in the x-axis direction are rounded. The non-display area NR is located around the display area DR. In this embodiment, the non-display area NR surrounds the display area.

[0022] The display area DR includes three or more divided areas arranged adjacent to each other along the x-axis. In this embodiment, the display area DR includes a first divided area DR1, a second divided area DR2, and a third divided area DR3. The second divided area DR2 is located between the first divided area DR1 and the third divided area DR3, and the third divided area DR3 is located on the positive side of the x-axis compared to the first divided area DR1. The first divided area DR1 and the second divided area DR2 are separated by boundary line BD12, and the second divided area DR2 and the third divided area DR3 are separated by boundary line BD23. Boundary lines BD12 and BD23 are parallel to the y-axis.

[0023] The first and third division regions DR1 and DR3 have a rectangular shape with one corner rounded, while the second division region DR2 has a rectangular shape. Therefore, in this embodiment, the shapes of two adjacent division regions in the display region DR are different from each other.

[0024] As shown in Figure 3, in each divided region, the maximum width in the x-axis direction is greater than the maximum height in the y-axis direction. In the first divided region DR1, the maximum width w1 is greater than the maximum height h1. Similarly, in the second divided region DR2, the maximum width w2 is greater than the maximum height h2, and in the third divided region DR3, the maximum width w3 is greater than the maximum height h3. In other words, the relationships w1>h1, w2>h2, and w3>h3 are satisfied. Also, in this embodiment, h1=h2=h3, and the relationship w3>w1>w2 is satisfied.

[0025] Figure 4A shows a schematic plan view of the active matrix substrate 40. In Figure 4A, for clarity, the first divided region DR1 and the second divided region DR2 are shown as rectangles. Also, for explanatory purposes, the first divided region DR1, the second divided region DR2, and the third divided region DR3 are shown as having the same shape.

[0026] The active matrix substrate 40 is provided with multiple scan lines GL, multiple data lines SL, multiple scan line connection lines BL, and multiple pixels PX in each of the first divided region DR1, the second divided region DR2, and the third divided region DR3.

[0027] In each divided region, multiple scan lines GL extend in the x-axis direction and are arranged in the y-axis direction. Similarly, multiple data lines SL extend in the y-axis direction and are arranged in the x-axis direction. Multiple scan line connection lines BL extend in the y-axis direction and are arranged in the x-axis direction. The scan lines GL in each divided region are not connected to the scan lines GL of adjacent divided regions.

[0028] Figure 5 is a circuit diagram showing an example configuration of a pixel PX. Each pixel PX is located in a region enclosed by a pair of data lines SL from a plurality of data lines SL and a pair of scan lines GL from a plurality of scan lines GL. A pixel PX includes a TFT and a pixel electrode PE. Specifically, the gate electrode of the TFT is connected to the scan line GL, the source electrode is connected to the data line SL, and the drain electrode is connected to the pixel electrode.

[0029] As shown in Figure 4A, the multiple scan line drive circuits 60 are arranged corresponding to the first divided region DR1, the second divided region DR2, and the third divided region DR3, respectively. Similarly, the multiple data line drive circuits 70 are also arranged corresponding to the first divided region DR1, the second divided region DR2, and the third divided region DR3, respectively.

[0030] Each of the multiple scan line drive circuits 60 and the multiple data line drive circuits 70 is arranged in the x-axis direction outside the display area DR. In this embodiment, the scan line drive circuits 60 and the data line drive circuits 70 are positioned on either side of the first divided area DR1, the second divided area DR2, and the third divided area DR3, and are arranged in the x-axis direction. The scan line drive circuits 60 are located in the non-display area NR, which is positive in the y-axis direction from each divided area. On the other hand, the data line drive circuits 70 are located on a flexible substrate 51 connected to the non-display area NR, which is negative in the y-axis direction from each divided area. However, as shown in Figure 4B, the multiple data line drive circuits 70 may be located in the non-display area NR.

[0031] In this embodiment, the scan line driving circuit 60 is formed integrally (monolithically) on the substrate 10. For example, the scan line driving circuit 60 includes a plurality of TFTs, and these TFTs and the pixel PX TFT are formed simultaneously. The scan line driving circuit 60 may consist of a bare chip or a packaged chip and be mounted on the non-display area NR of the substrate 10. The scan line driving circuit 60 may consist of a bare chip or a packaged chip and be mounted on a flexible substrate, and the flexible substrate may be mounted on the non-display area NR of the substrate 10.

[0032] The data line drive circuit 70 consists of a bare chip or a packaged chip and is mounted on the flexible substrate 51. The data line drive circuit 70 also consists of a bare chip or a packaged chip and may be mounted on the non-display area NR of the substrate 10.

[0033] In Figure 4A, each scan line drive circuit 60 is shown as two elements in each divided region, but the number of scan line drive circuits in each divided region may be one, or it may be divided into three or more. The same applies to the data line drive circuit 70; each data line drive circuit 70 is shown as four elements in each divided region, but the number of scan line drive circuits in each divided region may be one to three or five or more.

[0034] In each divided region, one end of each of the multiple data lines SL extends to the non-display region NR and is connected to the data line drive circuit 70 via wiring formed on the flexible substrate 51. Similarly, one end of each of the multiple scan line connection wirings BL extends to the non-display region NR and is connected to the scan line drive circuit 60 in each divided region. Each of the multiple scan line connection wirings BL is connected at a connection point CP located at a position where it intersects with one of the multiple scan lines GL. In this embodiment, for redundancy, a pair of adjacent scan line connection wirings BL are connected to the same scan line GL. The same scan signal is applied to the pair of adjacent scan line connection wirings BL. By adopting this configuration, even if one scan line connection wiring BL is disconnected or the connection at the connection point CP between the scan line connection wiring BL and the scan line GL is poor during the manufacturing of the display device 101, the connection between the scan line drive circuit and the scan line GL can be ensured by the other scan line connection wiring BL.

[0035] As described later, the scan line connection wiring BL is positioned within the pixel, which reduces the aperture ratio of the pixel. For this reason, to prevent a large change in the aperture ratio of pixels arranged in the y-axis direction, it is preferable that the scan line connection wiring BL extends in the y-axis direction from the scan line drive circuit 60 side, beyond the connection point CP, to the opposite side of the scan line drive circuit 60. For example, in each divided region, it is preferable that 70% or more of the scan line connection wirings among the multiple scan line connection wirings have a length of 70% or more of the y-axis width of the display area.

[0036] Furthermore, it is preferable that the number of scan lines GL located in one of a pair of adjacent divided regions is equal to the number of scan lines located in the other of the pair of divided regions. This ensures that the number of pixels in the y-axis direction is equal in the pair of adjacent divided regions. If the height in the y-axis direction of each divided region is equal, then when displaying a single integrated image across the entire display area DR, including the first divided region DR1, the second divided region DR2, and the third divided region DR3, the image can be displayed with a uniform pixel density throughout the entire display area.

[0037] The timing controller 92 is electrically connected to the scan line drive circuit 60 by wiring 21 located in the non-display area NR of the board 10 and on the flexible board 51 connected to the board 91. Similarly, the timing controller 92 is electrically connected to the data line drive circuit 70 by wiring on the flexible board 51.

[0038] The timing controller 92 outputs scan line drive circuit control signals necessary for generating scan signals to the scan line drive circuit 60 for each divided region, and outputs image signals that will be the basis of data signals to the data line drive circuit 70, in order to display independent images in the first divided region DR1, the second divided region DR2, and the third divided region DR3, respectively. For example, in order to display the first image in the first divided region DR1, the first scan line drive circuit control signal and the first image signal are output to the scan line drive circuit 60 and the data line drive circuit 70, respectively. Similarly, in order to display the second image in the second divided region DR2, the second scan line drive circuit control signal and the second image signal are output to the scan line drive circuit 60 and the data line drive circuit 70, respectively. In addition, in order to display the third image in the third divided region DR3, the third scan line drive circuit control signal and the third image signal are output to the scan line drive circuit 60 and the data line drive circuit 70, respectively. In Figure 4A, the timing controller 92 is shown as a single element, but the timing controller 92 may be divided into three parts corresponding to each divided region.

[0039] The timing controller 92 generates control signals and image signals for each scan line drive circuit and controls the scan line drive circuit 60 and the data line drive circuit 70 so that at least one of the first, second, and third images is displayed at a different frame frequency from the other two. For example, the first image is an image displaying various car meters such as a speedometer and a tachometer, and since it contains fast-moving images, it is displayed at a frame frequency of 120 Hz. The second image is an image of map information from a car navigation system, and since there are few fast-moving image changes, it is displayed at a frame frequency of, for example, 10 Hz. The third image is a general TV or video image such as a sports broadcast, and is displayed at a frame frequency of 60 Hz.

[0040] According to the display device 101, it is possible to display images at a different frame frequency in some of the divided areas of the display area DR compared to other areas. Therefore, it is possible to reduce power consumption by lowering the frame frequency of the images displayed in some of the divided areas. At the same time, by displaying images at a higher frame frequency in the other divided areas, it is possible to display fast motion smoothly, thus achieving both high-quality display and low power consumption.

[0041] Furthermore, multiple scan line drive circuits are arranged in the x-axis direction outside the display area, and are electrically connected to the scan lines and scan line drive circuits using scan line connection wiring that extends in the same direction as the data lines. This avoids placing the scan line drive circuits at the ends of the scan lines, i.e., adjacent to the divided areas in the x-axis direction. As a result, adjacent divided areas can be placed touching. Therefore, the seams between images displayed in the divided areas can be made less noticeable. For example, when the first, second, and third images are integrated to form a single image, the areas between the divided areas where images are not displayed can be reduced or eliminated, resulting in superior display.

[0042] As described above, when the first, second, and third images are integrated to form a single image, that is, when a single image is displayed across the entire display area DR, it is preferable that no difference in brightness occurs at the boundaries of the divided areas. To achieve such display, it is preferable that the position of the connection point CP between the scan line connection wiring BL and the scan line GL satisfies a specific relationship between the divided areas. This relationship will be described in detail below.

[0043] Figure 6 shows the arrangement of scan lines GL, scan line connection lines BL, and connection points CP in each divided region. In each divided region, one connection point CP1 is determined from among the multiple connection points CP that are arranged, and another connection point CP2 is determined which is located further from the upper edge DRe of the display region DR than connection point CP1.

[0044] Let L1a and L1b be the distances between connection points CP1 and CP2 located in one of a pair of adjacent divided regions separated by boundary lines BD12 and BD23, and between the boundary line and the connection point CP1 and CP2 located in the other of the pair of divided regions, and between the boundary line and the connection point CP1 and CP2, respectively.

[0045] In this embodiment, the distances L1a, L1b, L2a, and L2b satisfy the relationship shown in equation (1) below.

[0046] (L1b-L1a)×(L2b-L2a)>0 (1) For example, consider connection points CP1 and CP2 located in the first divided region DR1 and the second divided region DR2 in Figure 6. The distances L1a, L1b, L2a, and L2b between the boundary line BD12 located between the first divided region DR1 and the second divided region DR2 and the connection points are such that L1a > L1b in the first divided region DR1 and L2a > L2b in the second divided region DR2. Therefore, the relationship in equation (1) is satisfied.

[0047] Similarly, consider connection points CP1 and CP2 arranged in the second divided region DR2 and the third divided region DR3. The distances L1a, L1b, L2a, and L2b between the boundary line BD23 located between the second divided region DR2 and the third divided region DR3 and the connection points are such that L1a < L1b in the second divided region DR2 and L2a < L2b in the third divided region DR3. Therefore, the relationship of Equation (1) is satisfied.

[0048] That is, if the arrangement pattern of the connection points when the relationship between the distances of the connection points CP1 and CP2 and the boundary line is L1a > L1b or L2a > L2b is designated as A, and the arrangement pattern of the connection points when L1a < L1b or L2a < L2b is designated as B, then on the left and right sides of the boundary line, the AA or BB arrangement patterns satisfy the relationship of Equation (1).

[0049] Scanning signals for turning on / off each pixel PX output from the scanning line driving circuit are applied to the scanning line connection wiring BL and the scanning line GL. This scanning signal has a pulse waveform when output from the scanning line driving circuit. However, due to the parasitic resistance and parasitic capacitance corresponding to the distance from the scanning line driving circuit to the pixel PX, the waveform is distorted, and the effective time for which the pixel PX is turned on becomes shorter. As a result, the luminance of the pixel decreases according to the parasitic resistance and the amount of parasitics. In two adjacent divided regions sandwiching the boundary line, the influence of the parasitic resistance and parasitic capacitance in the pixel closest to the boundary line of each divided region can be evaluated as follows.

[0050] As shown in FIG. 7, in each divided region, the scanning line GL and the scanning line connection wiring BL are divided into four parts, the parasitic resistances of the divided parts are designated as Rg and Rb respectively, and the parasitic capacitances are designated as Cg and Cb respectively.

[0051] Figures 7(a), (b), and (c) schematically show the positions of connection points CP in the scan line connection wiring BL and scan line GL in the first divided region DR1, and Figures 7(d), (e), and (f) schematically show the positions of parasitic resistances Rg, Rb and parasitic capacitances Cg, Cb located from the scan line drive circuit to the pixel adjacent to the boundary line DB12 and affecting the scan line. Figures 7(a), (b), and (f) show the scan line GL at the top of each divided region in the y-axis direction, Figures 7(d), (e), and (f) show the scan line GL at the center of each divided region in the y-axis direction, and Figures 7(d), (e), and (f) show the scan line GL at the bottom of each divided region in the y-axis direction.

[0052] As shown in Figure 7, assuming that Rg / Cg and Rb / Cb are equal, the parasitic resistance and capacitance affecting pixels adjacent to the boundary line DB12 are equivalent to four Rg / Cg or Rb / Cb values ​​in each of (a) to (f). Therefore, the waveform distortion of the scan signal applied to the pixel closest to the boundary line DB12 in the first divided region DR1 and the pixel closest to the boundary line DB12 in the second divided region DR2 are similar, and are affected by parasitic resistance and capacitance to a similar degree. Consequently, the brightness reduction of pixels due to parasitic resistance and capacitance is also similar, and the pixels emit light at a similar brightness. In Figure 7 and the following Figures 8, 10, and 12, the shaded rectangles indicate the brightness of the pixels, with lighter shades indicating higher brightness. Therefore, the brightness difference between pixels on either side of the boundary line BD12 is small, and the boundary line is hardly noticeable. Furthermore, within the first divided region DR1, the brightness of pixels adjacent to the boundary line DB12 is approximately the same regardless of their position in the y-axis direction.

[0053] Figure 8 illustrates the effects of parasitic resistance and capacitance on pixels adjacent to the boundary line BD23 in the second and third divided regions DR2 and DR3. In the second and third divided regions DR2 and DR3, the effects of parasitic resistance and capacitance on pixels differ depending on their position in the y-axis direction. In other words, the lower the pixel is located, that is, the further it is located towards the negative side along the y-axis, the greater the effects of parasitic resistance and capacitance.

[0054] Specifically, as shown in (a) and (d), the pixels connected to the scanning line GL at the upper part in the y-axis direction of each divided region are affected by two parasitic resistances and parasitic capacitances of Rg / Cg or Rb / Cb. As shown in (b) and (e), the pixels connected to the scanning line GL at the central part in the y-axis direction of each divided region are affected by four parasitic resistances and parasitic capacitances of Rg / Cg or Rb / Cb. Also, as shown in (c) and (f), the pixels connected to the scanning line GL at the lower part in the y-axis direction of each divided region are affected by six parasitic resistances and parasitic capacitances of Rg / Cg or Rb / Cb.

[0055] Therefore, in each of the second divided region DR2 and the third divided region DR3, for the pixels adjacent to the boundary line BD23, the more downward the position, the greater the sag of the waveform of the applied scanning signal, and the lower the luminance of the pixels. However, if the positions in the y-axis direction are the same, the influence of the parasitic resistances and parasitic capacitances received by the pixels closest to the boundary line DB12 in the second divided region DR2 and the third divided region DR3 is about the same. For this reason, the luminance difference between the pixels sandwiching the boundary line BD23 is small, and the boundary line is hardly noticeable.

[0056] FIG. 9 shows an example where the distances L1a, L1b, L2a, and L2b do not satisfy Equation (1). As shown in FIG. 9, with respect to the boundary line BD12, for example, in the first divided region DR1, it is assumed that the relationship L1a > L1b is satisfied, and in the second divided region DR2, the relationship L2a < L2b is satisfied. That is, the arrangement pattern of AB is satisfied. In this case, as shown in (a) and (d) of FIG. 10, at the upper part in the y-axis direction, the pixels adjacent to the boundary line BD12 in the first divided region DR1 are more affected by the parasitic resistances and parasitic capacitances than the pixels adjacent to the boundary line BD12 in the second divided region DR2, and the luminance decreases. For this reason, the boundary line BD12 due to the luminance difference is noticeable.

[0057] Also, as shown in (c) and (f) of FIG. 10, in the lower part in the y-axis direction, pixels adjacent to the boundary line BD12 of the second divided region DR2 are more affected by parasitic resistance and parasitic capacitance than pixels adjacent to the boundary line BD12 of the first divided region DR1, and the luminance decreases. Therefore, the boundary line BD12 due to the luminance difference becomes conspicuous.

[0058] Also, as shown in FIG. 11, assume that with respect to the boundary line BD12, for example, in the first divided region DR1, the relationship L1a < L1b is satisfied, and in the second divided region DR2, the relationship L2a > L2b is satisfied. That is, the arrangement pattern of BA is satisfied. Also in this case, as shown in (a) and (d) of FIG. 12, in the upper part in the y-axis direction, pixels adjacent to the boundary line BD12 of the second divided region DR2 are more affected by parasitic resistance and parasitic capacitance than pixels adjacent to the boundary line BD12 of the first divided region DR1, and the luminance decreases. Therefore, the boundary line BD12 due to the luminance difference becomes conspicuous.

[0059] Also, as shown in (c) and (f) of FIG. 12, in the lower part in the y-axis direction, pixels adjacent to the boundary line BD12 of the first divided region DR1 are more affected by parasitic resistance and parasitic capacitance than pixels adjacent to the boundary line BD12 of the second divided region DR2, and the luminance decreases. Therefore, the boundary line BD12 due to the luminance difference becomes conspicuous.

[0060] Thus, according to the display device 101, by satisfying the relationship of the formula (1) for the position of the connection point between the scanning line GL and the scanning line connection wiring BL, in the vicinity of the boundary between two adjacent divided regions, the influence of the luminance decrease of the pixels due to the parasitic resistance and parasitic capacitance is suppressed, and a display in which a luminance difference (luminance separation) hardly occurs at the boundary between the two divided regions becomes possible.

[0061] In this embodiment, three divided regions are arranged along the x-axis direction. However, even when four or more divided regions are arranged, by repeating the arrangement patterns of the connection points in two divided regions sandwiching the boundary line as AA, BB, AA, BB ···, it is possible to display an image in which luminance differences hardly occur at any boundary line. Also, in this embodiment, in the first divided region and the second divided region, the arrangement pattern of the connection points is AA, but it may be BB. In this case, in the second divided region and the third divided region, the arrangement pattern of the connection points is AA.

[0062] In addition, when the arrangement of the connection points in two adjacent divided regions satisfies Equation (1), it is preferable that the direction in which the scanning line driving circuit 60 scans the scanning line connection wiring BL is different from the scanning direction of the scanning line driving circuit arranged in one region of a pair of adjacent divided regions sandwiching the boundary line and the scanning direction of the scanning line driving circuit arranged in the other region. Thus, by determining the scanning direction, the scanning directions of the scanning lines in two adjacent divided regions become equal to each other. Specifically, when the scanning lines in one region of a pair of adjacent divided regions are scanned from top to bottom, the scanning lines in the other region are also scanned from top to bottom. Also, when the scanning lines in one region of a pair of adjacent divided regions are scanned from bottom to top, the scanning lines in the other region are also scanned from bottom to top.

[0063] Also, when the relationships L1a > L1b and L2a > L2b are satisfied, by scanning the scanning line connection wiring in the direction toward the boundary line by the scanning line driving circuits of a pair of adjacent divided regions, the scanning lines GL of the pair of divided regions are each scanned from top to bottom. Also, when the relationships L1a < L1b and L2a < L2b are satisfied, by scanning the scanning line connection wiring in the direction away from the boundary line by the scanning line driving circuits of a pair of adjacent divided regions, the scanning lines GL of the pair of divided regions are each scanned from top to bottom.

[0064] Next, an example of a specific pixel configuration in the display device 101 will be described. Figure 13A is a plan view showing an enlarged portion of the active matrix substrate 40 of the display device 101. As shown in Figure 13A, each of the multiple pixels PX in this embodiment is either a red pixel (indicated by R), a green pixel (indicated by G), or a blue pixel (indicated by B). In addition, pixels of the same color are arranged in the y-axis direction, and in the x-axis direction, red pixels, green pixels, and blue pixels are arranged in this order in a repeating manner. The arrangement of the multiple pixels is not limited to this example, and may also include yellow pixels and white pixels. Furthermore, the arrangement of each pixel may follow a Bayer array. Furthermore, a configuration like that shown in Figure 13B is also acceptable, in which pixels of the same color are arranged in the x-axis direction, and red, green, and blue pixels are arranged in the y-axis direction in that order, repeating each other. In this configuration, although the scan lines need to be separated by the red, green, and blue pixels and scanned three times faster than the configuration shown in Figure 13A, the number of expensive data line driving circuits can be reduced to one-third because the data lines are shared by the red, green, and blue pixels. Furthermore, because pixels of the same color are arranged in the x-axis direction, if the liquid crystal display device has a structure in which a color filter is placed on the opposing substrate, color misalignment due to positional misalignment in the x-axis direction between the active matrix substrate and the opposing substrate can be suppressed. For example, if such a display device is curved along the x-axis direction, the position of the pixels on the active matrix substrate and the position of the pixels on the opposing substrate will be misaligned in the x-axis direction due to the difference in the radii of curvature between the active matrix substrate and the opposing substrate. However, since pixels of the same color are arranged in the x-axis direction, even if the position is misaligned, display in different colors is suppressed.

[0065] In the active matrix substrate 40, if the distance between a pair of pixels of the same color that are respectively included in adjacent pair of divided regions and are closest to each other in the x-axis direction is d1, and the distance between a pair of pixels of the same color that are respectively included in one of the adjacent pair of divided regions and are closest to each other in the x-axis direction is d2, it is preferable that d1 and d2 are equal. For example, as shown in FIGS. 13A and 13B, the distance between the green pixel closer to the boundary line BD12 in the first divided region DR1 and the green pixel closer to the boundary line BD12 in the second divided region DR2 is d1, and when the distance between the two closest green pixels in the x-axis direction of the first divided region DR1 is d2, d1 = d2. When the distance between the two closest green pixels in the x-axis direction of the second divided region DR2 is d2', it is more preferable that d1 = d2 = d2'.

[0066] By satisfying this relationship, the first divided region DR1 and the second divided region DR2 are continuous in the x-axis direction without an extra space being arranged between the two pixels sandwiching the boundary line BD12. Therefore, when integrally displaying an image continuous in the first divided region DR1 and the second divided region DR2, no break occurs at the boundary of the divided regions, and excellent display can be performed.

[0067] Also, it is preferable that each scanning line arranged in one of the adjacent pair of divided regions overlaps with one of the plurality of scanning lines arranged in the other in the y-axis direction when viewed from the x-axis direction. For example, as shown in FIG. 14, the scanning line GL in the first divided region DR1 overlaps with the scanning line GL in the second divided region DR2 in the region indicated by the oblique lines in the y-axis direction. That is, it is preferable that the deviation amount Pe in the y-axis direction between the scanning line GL in the first divided region DR1 and the scanning line GL in the second divided region DR2 is smaller than the width Wg of the scanning line GL (Pe < Wg). More preferably, Pe < 1 / 2Wg is satisfied. It is also preferable that the same relationship is satisfied for the scanning line GL arranged in the second divided region DR2 and the third divided region DR3.

[0068] By arranging the scan lines GL in this way, the shift in the y-axis direction between pixels in the first division area DR1 and pixels in the second division area DR2 at the boundary line BD12 is suppressed. Therefore, when displaying an image continuous in the first division area DR1 and the second division area DR2 as a single unit, no breaks in the division areas occur, resulting in superior display. Similarly, the shift in the y-axis direction between pixels in the second division area DR2 and pixels in the third division area DR3 at the boundary line BD23 is suppressed. Therefore, when displaying an image continuous in the first division area DR1, the second division area DR2, and the third division area DR3 as a single unit, no breaks in the division areas occur, resulting in even superior display.

[0069] In each divided region, multiple scan line connection lines BL are arranged in the x-axis direction with the x-axis arrangement pitch of pixels of the same color among multiple pixels PX. For example, as shown in Figure 13A, in the first divided region DR1, the x-axis arrangement pitch of green pixels is d2, so the arrangement pitch p1 of the scan line connection lines BL is equal to d2. Similarly in the second divided region DR2, the arrangement pitch p2 of the scan line connection lines BL is equal to d2'.

[0070] Furthermore, it is preferable that each scan line connection wiring BL overlaps with either a blue pixel or a red pixel, or both, among the red, green, and blue pixels adjacent in the x-axis direction. In the example shown in Figure 13A, the scan line connection wiring overlaps with a blue pixel and is located on the blue pixel. As mentioned above, placing the scan line connection wiring BL reduces the aperture ratio of the pixel on which the scan line connection wiring BL is located. Of the red, blue, and green pixels, the human eye has a higher visual sensitivity to green than to red and blue, so if the aperture ratio is reduced by placing the scan line connection wiring BL on a green pixel, the decrease in brightness is strongly perceived. For this reason, by placing the scan line connection wiring BL on a red or blue pixel, where the impact on brightness due to the reduction in aperture ratio is relatively small, the impact on brightness due to the reduction in aperture ratio can be further suppressed.

[0071] Figure 15 shows an example of the cross-sectional structure of a liquid crystal display device in line AA of Figure 13A. In the active matrix substrate 40, a first insulating layer 11 is placed on the substrate 10, and data lines SL and scan line connection wiring BL are placed on the first insulating layer 11. The data lines SL and scan line connection wiring BL extend in the y-axis direction and do not intersect with each other. For this reason, they can be constructed from metal layers of the same layer. For example, by forming a metal layer so as to cover the first insulating layer 11 and performing patterning, the data lines SL and scan line connection wiring BL can be formed simultaneously.

[0072] A second insulating layer 12 is placed on the first insulating layer 11, covering the data line SL and the scan line connection wiring BL. An interlayer insulating layer 13 is placed on the second insulating layer 12 to flatten the irregularities of the second insulating layer 12. Pixel electrodes PE are placed on the interlayer insulating layer 13, and a third insulating layer 14 is placed to cover the pixel electrodes PE. Furthermore, a common electrode 15 is placed on the third insulating layer.

[0073] The opposing substrate 80 is arranged corresponding to the active matrix substrate 40 at a predetermined distance, and the liquid crystal layer 81 is arranged between the opposing substrate 80 and the active matrix substrate 40.

[0074] Since the scan line connection wiring BL can be formed from the same metal layer as the data line SL, it is possible to form the scan line connection wiring without increasing the manufacturing process.

[0075] As mentioned above, it is preferable that the scan line connection wiring BL is arranged in the x-axis direction at the same pitch as the arrangement pitch of pixels of the same color in the x-axis direction. If this arrangement is followed, when the number of pixels that form a set of adjacent red, blue, and green pixels in the x-axis direction is greater than the number of pixels in the y-axis direction, there will be pixels where scan line connection wiring BL is not placed. In this case, the aperture ratio of the pixels where scan line connection wiring BL is not placed will be high, and the aperture ratio of pixels in each divided region will not be uniform.

[0076] In such cases, the active matrix substrate 40 may further include at least one dummy scan line connection wiring extending in the y-axis direction and arranged in the x-axis direction. Figure 16 is a schematic enlarged plan view of the active matrix substrate 40' further comprising dummy scan line connection wiring DL. The scan line connection wiring BL and the dummy scan line connection wiring DL are arranged in the x-axis direction at the array pitch p1 of the scan line connection wiring BL described above. That is, if the scan line connection wiring BL is located on a blue pixel, the dummy scan line connection wiring DL is also located on a blue pixel.

[0077] This ensures that either a scan line GL or a dummy scan line connection wiring DL is placed in the blue pixel. Thus, it is possible to avoid variations in the aperture ratio of the blue pixel depending on its location.

[0078] The dummy scan line connection wiring DL is not involved in driving the scan line GL, and therefore is not connected to either the scan line drive circuit 60 or the scan line GL. However, if the floating electrodes are not connected to any potential, problems may arise such as static electricity accumulation or potential differences due to differences in the amount of charge accumulated between the dummy scan line connection wirings DL. For this reason, the active matrix substrate 40 is further provided with at least one common wiring CL extending in the x-axis direction, and it is preferable that each dummy scan line connection wiring DL is connected to at least one common wiring CL. The common wiring CL is connected to an electrode to which a predetermined potential, such as a reference potential, is applied. Multiple dummy scan line connection wiring DLs may be connected to the same common wiring CL.

[0079] Common wiring CL intersects, for example, with scan line connection wiring BL. Also, common wiring CL intersects with data wiring.

[0080] In this way, by placing dummy scan line connection wiring DL in pixels where scan line connection wiring BL is not placed, the aperture ratio of the pixels can be kept constant. Furthermore, if the number of pixels in a set of adjacent red, blue, and green pixels in the x-axis direction is more than twice the number of pixels in the y-axis direction, a configuration can be adopted in which redundancy is provided in the scan line connection wiring, as shown in Figure 4A, and two adjacent scan line connection wires BL are connected to the same scan line GL. Additionally, a dummy scan line DL may be provided as needed.

[0081] Various modifications are possible to the display device 101 of this disclosure. First, in the above embodiment, the display device is a liquid crystal display device, but as described above, it may be a display device having other structures such as an organic EL display device. The display device of this disclosure can be suitably used in display devices with various structures in which a scanning signal is selectively applied to the scanning line to turn on the pixels connected to the selected scanning line, and each pixel lights up with a brightness according to the data signal supplied from the data line.

[0082] Furthermore, in this embodiment, the scan line drive circuit 60 and the data line drive circuit 70 were facing each other across each divided region. However, the scan line drive circuit 60 may be located on the same side as the data line drive circuit 70 with respect to each divided region.

[0083] For example, as shown in Figure 17, the scan line drive circuit may be placed on the same flexible substrate 51 as the data line drive circuit. In this case, for example, if the data lines that drive the red, green, and blue pixels are SLr, SLg, and SLb, respectively, then each scan line connection wiring BL may be placed adjacent to the data line SLr for driving the red pixel. For example, wiring that connects to the data lines SLr, SLg, and SLb may be placed on the front side of the flexible substrate 51, and wiring that connects to the scan line connection wiring BL may be placed on the back side.

[0084] Alternatively, as shown in Figure 18, a drive circuit 65 may be configured by housing a scan line drive circuit and a data line drive circuit in a single package and placing it on the flexible substrate 51. In other words, the drive circuit 65 may serve as both a scan line drive circuit and a data line drive circuit. The drive circuit 65 may be configured, for example, as in Figure 17, with data lines SLr, SLg, SLb, and scan line connection wiring BL arranged in the x-axis direction, and connected to the drive circuit 65.

[0085] Furthermore, the shape and size of the display area DR, and the number of divided areas included in the display area DR, are merely examples, and the shape, size, and number are not limited to the above embodiment.

[0086] The display device of this disclosure can also be described as follows: The display device relating to the first configuration of this disclosure is A substrate having a main surface having a display area and a non-display area located around the display area, wherein the display area includes three or more divided areas arranged adjacent to each other along a first direction, A plurality of scan lines arranged in each divided region, the plurality of scan lines extending in a first direction and arranged in a second direction intersecting the first direction, Multiple data lines are arranged in each divided region, and each of these data lines extends in a second direction and is arranged in a first direction. Multiple pixels are arranged in each divided region, and each of these pixels is arranged in a region surrounded by a pair of data lines and a pair of scan lines.

Each scan line connection wire electrically connects the scan line drive circuit to one of the multiple scan lines. The scan line drive circuit and the data line drive circuit display the image in at least one of the three or more divided regions at a different frame frequency than the other divided regions.

[0087] According to the first configuration, since a portion of the display area can be driven at a different frame frequency, power consumption can be reduced. Furthermore, because the scan line drive circuit and data line drive circuit are arranged in the first direction, adjacent divided areas can be placed adjacent to each other, making the seams between images displayed in the divided areas less noticeable.

[0088] In the display device according to the second configuration, the scan line drive circuit and data line drive circuit for each divided region may be facing each other across the divided region in the first configuration.

[0089] In the third configuration of the display device, in the first or second configuration, the multiple scan lines of each divided region do not need to be connected to the multiple scan lines of adjacent divided regions.

[0090] The display device relating to the fourth configuration is configured in any one of the first to third configurations. Each scan line connection wire is electrically connected to one of the multiple scan lines at the connection point. Among three or more divided regions, if there are multiple connection points within one of a pair of adjacent divided regions separated by a boundary line, let L1a be the distance between one connection point and the boundary line, and let L1b be the distance between another connection point that is further from the top edge of the display region than the other connection point and the boundary line. If, among multiple connection points within the other of a pair of divided regions, L2a is the distance between one connection point and the boundary line, and L2b is the distance between another connection point that is further from the top edge of the display region than the first connection point and the boundary line,

[0091] (L1b-L1a)×(L2b-L2a)>0 The following relationship may also be satisfied. By satisfying this relationship, it becomes possible to display without brightness separation at the boundary.

[0092] In the fifth configuration, the display device may have, in any one of the first to fourth configurations, a plurality of scan line connection lines and a plurality of data lines made of the same layer of metal. This configuration allows for the formation of scan line connection wiring without increasing the manufacturing process.

[0093] In the sixth configuration of the display device, in any one of the first to fifth configurations, the scanning direction of the scan line drive circuit located in one of a pair of adjacent divided regions separated by a boundary line may be different from the scanning direction of the scan line drive circuit located in the other of the pair of divided regions. This makes it possible to perform scanning without brightness separation at the boundary.

[0094] In the seventh configuration of the display device, in any one of the first to sixth configurations, each scan line connection wiring may extend beyond the connection point in the second direction.

[0095] In the display device according to the eighth configuration, in the seventh configuration, 70% or more of the scan line connection wirings among the plurality of scan line connection wirings may have a length of 70% or more of the width of the display area in the second direction.

[0098] In the display device according to the 11th configuration, in any one of the 1st to 10th configurations, either one or both of the blue pixels or red pixels among the red, green, and blue pixels adjacent in the first direction may overlap with one of the multiple scan line connection lines.

[0099] The display device according to the 12th configuration further comprises, in any one of the first to 11th configurations, at least one dummy scan line connection wiring arranged in the display area, extending in a second direction and arranged in a first direction, wherein the at least one dummy scan line connection wiring does not have to be connected to a scan line drive circuit and a plurality of scan lines. By arranging the dummy scan line connection wiring, the aperture ratio of each pixel can be made uniform.

[0100] The display device according to the 13th configuration includes, in any one of the first to 12 configurations, at least one common wiring extending in a first direction and a plurality of dummy scan line connection wirings, wherein the plurality of dummy scan line connection wirings may be connected to at least one common wiring.

[0103] In the display device according to the 16th configuration, in any one of the 1st to 15th configurations, each scan line located in one of a pair of adjacent divided regions from among three or more divided regions may overlap with one of a plurality of scan lines located in the other of the pair of divided regions in a second direction when viewed from a first direction.

[0104] In the display device according to the 17th configuration, in any one of the 1st to 16th configurations, the number of scan lines placed in one of a pair of adjacent divided regions is equal to the number of scan lines placed in the other of the pair of divided regions.

[0105] In the 18th configuration of the display device, in any one of the 1st to 17th configurations, if d1 is the distance between the closest pair of pixels of the same color in the first direction, and d2 is the distance between the closest pair of pixels of the same color in the first direction, and d2 is the distance between the closest pair of pixels of the same color in the first direction, and each of the three or more divided regions is included in one of the adjacent divided regions, then d1 and d2 may be equal. Since the pitch of the pixels on either side of the boundary is equal to the pitch of the pixels within the divided region, the pitch of the pixels in the entire divided region is equal and no boundary is created. In other words, a single continuous image can be displayed across the entire divided region.

[0106] In the display device relating to the 19th configuration, in any one of the 1st to 18th configurations, the maximum width in the first direction may be greater than the maximum height in the second direction in each divided region.
