Abstract
Description
Technical Field
[0001] The present invention relates to display technology, and in particular to an array substrate and a display device. Background Art
[0002] Liquid crystal display panels have been widely used. Typically, a liquid crystal display panel includes an opposing substrate and an array substrate facing each other. Thin-film transistors, gate lines, data lines, pixel electrodes, common electrodes, and common electrode signal lines are arranged on the array substrate and the opposing substrate. Liquid crystal material is injected between the two substrates to form a liquid crystal layer. A common problem associated with liquid crystal display panels is light leakage. To prevent light leakage, a black matrix is provided on the opposing substrate. Liquid crystal display panels with a larger black matrix can better prevent light leakage. However, the use of a black matrix with a larger area reduces the aperture ratio of the liquid crystal display device.
[0003] Organic light-emitting diode (OLED) displays are driven by a drive current that needs to be kept constant to control light emission. The OLED display panel includes a plurality of pixel units configured with pixel drive circuits arranged in multiple rows and columns. Each pixel drive circuit includes a drive transistor having a gate terminal connected to a gate line for each row and a drain terminal connected to a data line for each column. When the row in which the pixel unit is selected is turned on, the switching transistor connected to the drive transistor is turned on, and the data voltage is applied from the data line to the drive transistor via the switching transistor, so that the drive transistor outputs a current corresponding to the data voltage to the OLED device. The OLED device is driven to emit light of corresponding brightness. Summary of the Invention

[0066] The present disclosure will now be described in more detail with reference to the following examples. It should be noted that the following description of some of the embodiments presented herein is for illustration and description purposes only. It is not intended to be exhaustive or limited to the precise forms disclosed.
[0067] The present disclosure, in particular, provides an array substrate and a display device that substantially overcome one or more problems caused by limitations and shortcomings of the prior art. In one aspect, the present disclosure provides an array substrate. In some embodiments, the array substrate includes a plurality of sub-pixels in at least one region. Optionally, the light-emitting region of each of the plurality of sub-pixels has a first end and a second end, with the second end located on a side of the first end away from a common reference region for the plurality of sub-pixels in the region. Optionally, directions from the second ends to the first ends of the plurality of sub-pixels are substantially directed toward the common reference region. Optionally, in the region, the number of pixels per inch (PPI) is substantially the same based on the distance from the common reference region. Optionally, in the region, the plurality of sub-pixels include first sub-pixels in a first orientation and second sub-pixels in a second orientation. Optionally, the width of the first light-emitting region of each of the first sub-pixels increases from the first end to the second end. Optionally, the width of the second light-emitting region of each of the second sub-pixels decreases from the first end to the second end. Optionally, the first orientation and the second orientation are substantially opposite to each other.
[0068] Figure 1 Schematic diagram showing the structure of an array substrate in some embodiments of the present disclosure. Figure 1 The array substrate includes a plurality of sub-pixels sp. The plurality of sub-pixels sp are arranged around the same reference region RR. Figure 1 An array substrate is shown, wherein a plurality of sub-pixels sp are arranged in a plurality of rings, each ring surrounding the same reference region RR. In a specific example, the plurality of rings surround the same reference center, for example, the plurality of rings are concentric.
[0069] Each sub-pixel in the plurality of sub-pixels sp can have various suitable shapes. Examples of suitable shapes include rectangles, squares, triangles, polygons, and irregular shapes. In one example, each sub-pixel has an elongated shape, the width of which increases or decreases along the extension direction or length direction of the elongated shape. In one example, the width at one end of the elongated shape is substantially zero. As used herein, the term "sub-pixel" refers to a portion of a pixel that can be independently addressed to emit a specific color (e.g., red, green, blue, or white).
[0070] Figure 2 Schematic diagram showing the structure of the shape of corresponding sub-pixels in some embodiments of the present disclosure. Figure 2 The light emitting region of each of the plurality of sub-pixels sp has a first end E1 and a second end E2. The second end E2 is located on a side of the first end E1 away from the same reference region RR of the plurality of sub-pixels sp in at least one region of the array substrate.
[0071] Reference Figure 1 and Figure 2 , the multiple sub-pixels sp can be oriented in various directions. However, the direction from the second end to the first end of the light-emitting region of the multiple sub-pixels sp substantially points to the same reference region RR. As used herein, the term "substantially points to or substantially points to" means that the extension direction of the line connecting the midpoint of the light-emitting region of each sub-pixel on the side of the second end and the midpoint of the light-emitting region of the sub-pixel on the side of the first end intersects the same reference region RR.
[0072] The same reference region RR may have various suitable shapes. Examples of suitable shapes of the same reference region RR include a circle, a square, a rectangle, an ellipse, a triangle, a polygon, and an irregular shape. The same reference region RR may have various suitable sizes. In some embodiments, the width of the same reference region RR is less than ten times the maximum length of each sub-pixel, for example, less than nine times the maximum length of each sub-pixel, less than eight times the maximum length of each sub-pixel, less than seven times the maximum length of each sub-pixel, less than six times the maximum length of each sub-pixel, less than five times the maximum length of each sub-pixel, less than four times the maximum length of each sub-pixel, less than three times the maximum length of each sub-pixel, less than two times the maximum length of each sub-pixel, or less than the maximum length of each sub-pixel.
[0073] In some embodiments, the plurality of sub-pixels sp arranged above are limited to one area of the array substrate.

[0074] In another example, referring to Figure 3 The array substrate includes a plurality of sub-pixels sp surrounding a window region WR in the array substrate. The window region WR may be an area for mounting components such as a camera or a fingerprint sensor below the light emitting element. The same reference region may be the window region WR.
[0075] The array substrate can have various suitable shapes. Figure 1 In one example shown, the array substrate has a circular shape. Examples of suitable shapes of the array substrate also include square, rectangle, ellipse, triangle, polygon, and irregular shapes.
[0076] Reference Figure 1 In some embodiments, the array substrate further includes a black matrix in the inter-subpixel region of the array substrate.
[0077] Figure 4A Schematic diagram showing the arrangement of pixels in an array substrate according to some embodiments of the present disclosure. Figure 4A The array substrate includes a plurality of pixels pxl, and each pixel includes one or more sub-pixels. Figure 4A An example is shown in which a single pixel includes three sub-pixels of different colors, for example, a red sub-pixel, a green sub-pixel, and a blue sub-pixel. The pixel arrangement may be different in different parts of the array substrate.
[0078] Figure 4B N parts of an array substrate according to some embodiments of the present disclosure are shown. Figure 4B Describes the Figure 4A The array substrate described in corresponds to the portion of the array substrate.

The first portion P1 surrounds the same reference region RR, the second portion surrounds the first portion P1, the nth portion Pn surrounds the (n-1)th portion, and the Nth portion PN surrounds the (N-1)th portion.
[0079] In some embodiments, reference Figure 4A , in this region, the number of sub-pixels per unit area is substantially the same depending on the distance from the same reference region RR. For example, in this region, the number of pixels per inch (PPI) is substantially the same depending on the distance from the same reference region RR. As used herein, the term "substantially the same" means that the difference between two values does not exceed 10% of a base value (e.g., one of the two values), for example, not exceeding 8% of the base value, not exceeding 6% of the base value, not exceeding 4% of the base value, not exceeding 2% of the base value, not exceeding 1% of the base value, not exceeding 0.5% of the base value, not exceeding 0.1% of the base value, not exceeding 0.05% of the base value, or not exceeding 0.01% of the base value. In some embodiments, the area of each sub-pixel in the region is substantially the same. In some embodiments, the number of sub-pixels in the N portions increases as the distance from the same reference region RR increases.

In one example, the first orientation O1 and the second orientation O2 are arranged substantially opposite to each other. As used herein, the term "substantially opposite to each other" means that the offset angle between the two orientations is in the range of 70 degrees to 110 degrees, for example, 70 degrees to 75 degrees, 75 degrees to 80 degrees, 80 degrees to 85 degrees, 85 degrees to 90 degrees, 90 degrees to 95 degrees, 95 degrees to 100 degrees, 100 degrees to 105 degrees, or 105 degrees to 110 degrees.

Alternatively, a plurality of adjacent sub-pixels in each of the N parts constitute a pixel.
[0082] Reference Figure 4B and Figure 6A , N portions (P1, ..., Pn, ..., PN) are sequentially arranged in the region. In some embodiments, the (n+1)th portion P(n+1) is located on a side of the nth portion Pn away from the same reference region, 1≤n≤(N-1).

[0083] Alternatively, in some embodiments, the sub-pixel in the nth part Pn that is directly adjacent to the (n+1)th part P(n+1) and the sub-pixel in the (n+1)th part P(n+1) that is directly adjacent to the nth part Pn have different orientations, wherein the narrower end of the light-emitting area of the sub-pixel in the nth part that is directly adjacent to the (n+1)th part is directly adjacent to the narrower end of the light-emitting area of the sub-pixel in the (n+1)th part that is directly adjacent to the nth part.
[0084] In some embodiments, the ratio of the number of sub-pixels having the first orientation to the number of sub-pixels having the second orientation in the nth portion is greater than the ratio of the number of sub-pixels having the first orientation to the number of sub-pixels having the second orientation in the (n+1)th portion. Optionally, the first portion includes only a plurality of sub-pixels having the first orientation.

Figure 10A In some embodiments, the array substrate includes N sections (P1 to PN). In some embodiments, the array substrate includes N gate lines and (J×(2N-1)) data lines. J represents the number of sub-pixels in section 1 of the N sections.

[0115] Figure 11A The diagram shows the layout of signal lines in an array substrate according to some embodiments of the present disclosure. Figure 11B The diagram shows the layout of gate lines in an array substrate according to some embodiments of the present disclosure. Figure 11C The diagram shows the layout of data lines in an array substrate according to some embodiments of the present disclosure. Figures 11A to 11C The layout of the signal lines shown can be applied to, for example, Figure 1 、 Figure 6A 、 Figure 9A or Figure 10A The array substrate shown. Figures 11A to 11C In some embodiments, the array substrate includes a plurality of data lines DL, a plurality of gate lines GL, one or more on-array-substrate gate driving circuits GOA configured to provide gate driving signals to the plurality of gate lines, and a plurality of connection lines CL.
[0116] In some embodiments, the array substrate includes M gate lines (e.g., GL1, GL2, GL3, GL4, and GL5), which are arranged as M partial circles surrounding the same reference area; and (M-1) connecting lines (e.g., CL1, CL2, CL3, and CL4). The (M-1) connecting lines are located on a different layer from the M gate lines.
[0117] In some embodiments, the i-th connection line among the (M-1) connection lines electrically connects the (i+1)-th gate line to the gate drive circuit on the array substrate, where 1≤i≤(M-1). For example, CL1 electrically connects GL2 to the gate drive circuit on the array substrate; CL2 electrically connects GL3 to the gate drive circuit on the array substrate; CL3 electrically connects GL4 to the gate drive circuit on the array substrate; and CL4 electrically connects GL5 to the gate drive circuit on the array substrate.

[0120] The array substrate according to the present disclosure is particularly advantageous for manufacturing display panels with curved edges (e.g., circular display panels). In related display panels, subpixels are typically fabricated to have rectangular shapes. When forming the curved edges of related display panels, subpixels adjacent to the curved edges must be cut. Segmenting rectangular subpixels along the curved edges often results in subpixels of different colors (e.g., red subpixels, green subpixels, and blue subpixels) having significantly different areas, or even results in the loss of subpixels of one or more colors along the curved edges. When a black matrix with curved edges is used along the curved edges, display panels of the related art are prone to rainbow pattern defects. To eliminate the rainbow pattern defects, a black matrix can be applied to the segmented subpixels along the curved edges. However, this embodiment results in jagged edge defects in display panels of the related art. Therefore, in display panels of the related art, it is difficult to simultaneously eliminate both rainbow pattern defects and jagged edge defects. Alternatively, subpixels along the curved edges of display panels of the related art can be fabricated to have smaller sizes. However, this embodiment still cannot completely eliminate both rainbow pattern defects and jagged edge defects. Furthermore, making the sub-pixels along the curved edges smaller may result in "local dotted lines along the edges," which adversely affects the display quality.
[0121] Figure 13 Several defects along the curved edges in the display panel of the related art are shown. The array substrate according to the present disclosure effectively avoids these defects.
