AI Technical Summary
In display panels, as resolution and refresh rate increase, the overlap of signal transmission lines and power lines leads to capacitance differences, resulting in uneven brightness of the display panel, especially at low grayscale levels.
By setting the overlap area ratio between signal transmission lines and power lines to 0.95 to 1.05, the capacitance generated by the overlap of each signal transmission line and power line is similar, thereby reducing the signal difference between signal transmission lines.
This ensures the display panel's display quality and solves the problem of uneven brightness, especially reducing brightness differences at low grayscale levels.

[0033] Detailed Explanation
[0034] This disclosure describes several embodiments, but these descriptions are exemplary and not restrictive, and many more embodiments and implementations are possible within the scope of the embodiments described herein, which will be apparent to those skilled in the art. Although many possible combinations of features are shown in the drawings and discussed in the detailed description, many other combinations of the disclosed features are also possible. Unless specifically limited, any feature or element of any embodiment may be used in combination with or in lieu of any other feature or element in any other embodiment.
[0035] This disclosure includes and contemplates combinations of features and elements known to those skilled in the art. The embodiments, features, and elements disclosed in this disclosure may also be combined with any conventional features or elements to form a unique inventive scheme as defined by the claims. Any feature or element of any embodiment may also be combined with features or elements from other inventive schemes to form another unique inventive scheme as defined by the claims. Therefore, it should be understood that any feature shown and / or discussed in this disclosure may be implemented individually or in any suitable combination. Therefore, the embodiments are not limited except by the limitations imposed by the appended claims and their equivalents. Furthermore, various modifications and changes may be made within the scope of the appended claims.
[0036] Furthermore, in describing representative embodiments, the specification can have presented the method and / or process as a particular sequence of steps. However, to the extent that the method or process depends on the performance of such steps, the method or process is not limited to the performance of the steps in the specific order described. One of ordinary skill in the art, based on the present description and teachings, can recognize that other steps can be performed and / or described in other sequences, as appropriate. The recitation of steps in the claims does not imply that the order of the steps is important to the claims. Furthermore, the claims can be written to cover a process performed in different orders or permutations, as the spirit and scope of the disclosure will encompass such orderings and permuta tions.
[0037] In the drawings, the size, the thickness or the region of one or plural constituent elements, a layer, or the like, is sometimes exaggerated for the sake of clarity in some cases. Furthermore, the drawings schematically show ideal examples, and one embodiment of the present disclosure is not limited to shapes or numerical values shown in the drawings and the like.
[0038] The ordinal numbers "first", "second", "third", and the like, in the specification are used to avoid confusion among constituent elements, and are not intended to indicate or imply a relative importance of the constituent elements. "A plurality of" in the present disclosure means two or more.
[0039] In the present specification, words "central", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, which indicate the orientation or positional relationship of the constituent elements, are used to describe the positional relationship of the constituent elements with reference to the drawings, and are merely intended to facilitate the description of the specification and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present disclosure. The positional relationship of the constituent elements is appropriately changed according to the direction of the constituent elements described. Therefore, it is not limited to the words described in the specification, and can be appropriately changed according to the situation.
[0040] In the present specification, unless explicitly defined and limited otherwise, the terms "mount", "connected", "connected" should be interpreted broadly. For example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate, or communication between two elements inside. For those of ordinary skill in the art, the meaning of the above terms in the present disclosure can be understood according to the situation.
[0041] In this specification, a transistor refers to an element including at least a gate electrode, a drain electrode, and a source electrode. The transistor has a channel region between the drain electrode (a drain terminal, a drain region, or a drain electrode) and the source electrode (a source terminal, a source region, or a source electrode), and current can flow through the drain electrode, the channel region, and the source electrode. Note that, in this specification, the channel region refers to a region where current flows mainly.
[0042] In this specification, the first electrode can be a drain electrode and the second electrode can be a source electrode, or the first electrode can be a source electrode and the second electrode can be a drain electrode. In the case of using a transistor having opposite polarity or in the case of changing the direction of current flowing in a circuit, the functions of the "source electrode" and the "drain electrode" are sometimes interchanged with each other. Thus, in this specification, the "source electrode" and the "drain electrode" can be interchanged with each other, and the "source terminal" and the "drain terminal" can be interchanged with each other.
[0043] In this specification, "electrically connected" includes the case where components are connected through an element having some function. The element having some function is not particularly limited as long as it can transmit an electrical signal between components to be connected. Examples of the element having some function include not only an electrode and a wiring but also a switching element such as a transistor, a resistor, an inductor, a capacitor, and another element having some function.
[0044] In this specification, "parallel" refers to a state where an angle formed between two straight lines is greater than or equal to -10° and less than or equal to 10°, and thus includes a state where the angle is greater than or equal to -5° and less than or equal to 5°. In addition, "perpendicular" refers to a state where an angle formed between two straight lines is greater than or equal to 80° and less than or equal to 100°, and thus includes a state where the angle is greater than or equal to 85° and less than or equal to 95°.
[0045] Embodiments of the present disclosure will be described in detail below with reference to the drawings.
[0046] FIG. 1 is a structural schematic diagram of a display panel in an embodiment of the present disclosure. As shown in FIG. 1, the display panel provided in the embodiment includes a display area 100 and a non-display area located at the periphery of the display area 100. The non-display area includes a binding area 700 located at one side of the display area 100 along a second direction Y, a first peripheral area 200 located between the display area 100 and the binding area 700, and a second peripheral area 300 located at the periphery of the display area 100 and away from one side of the binding area 400. The first peripheral area 200 and the second peripheral area 300 are in communication and surround the display area 100. The display area 100 includes at least a plurality of sub-pixels P arranged regularly, for example, the plurality of sub-pixels P can be arranged in an array along a first direction X and the second direction Y, and the first direction X and the second direction Y are perpendicular to each other. The plurality of sub-pixels P are configured to display dynamic pictures or still images, and the display area 100 can be referred to as an active area (AA). A column of sub-pixels P arranged along the second direction Y can be connected to the same data line 101, and a plurality of data lines 101 can be connected to an integrated circuit 120 subsequently bound to the display panel. The integrated circuit 120 provides a data signal to the corresponding sub-pixel P through the data line 101 to drive the sub-pixel P to display. In an exemplary embodiment, the display panel can be deformable, for example, curled, bent, folded or rolled up. The display panel includes an upper frame and a lower frame oppositely arranged along the second direction Y, and a left frame and a right frame oppositely arranged along the first direction X. The lower frame is the frame on the side where the binding area 700 is located, and the frame opposite to the binding area 700 along the second direction Y can be referred to as the upper frame. The right frame is located at one side of the left frame along the first direction X.
[0047] In an exemplary embodiment, the shape of the display area 100 can be a quadrilateral, a circle, an ellipse, a polygon of other shapes, or an irregular shape, and the corner shape of the display area 100 can be a rounded corner. The present disclosure does not limit the shape of the display area 100. In an exemplary embodiment, the shape of the display area edge at different frames is different from the shape of the display area, for example, it can be a straight line, a curve, a broken line, or other shapes. The present disclosure does not limit the shape of the display area edge.
[0048] In an example embodiment, the first peripheral area 200 can include, in sequence along a direction away from the display area 100, a fan-out area 400, a bending area 500, and a driving chip area 600. The fan-out area 400 is connected to the display area 100 and can include at least a plurality of data lead-out lines. The signal lines such as the power lines, the data lines 101 of the display area 100 can pass through the fan-out area 400 in a fan-out manner and be connected to corresponding signal providing ends. A subsequent integrated circuit (IC) 120 can be connected to the driving chip area 600 in a binding manner. The integrated circuit 120 is configured to be connected to the plurality of data lead-out lines. The binding area 700 can include at least a plurality of bonding pads 701. A flexible printed circuit (FPC) or a chip on flex (COF) can be connected to the bonding pads 701 of the binding area 700 in a binding manner.
[0049] In an example embodiment, the first peripheral area 200 includes at least a power line configured to transmit a voltage signal to the plurality of sub-pixels P. As shown in FIG. 1, the power line can include a first power line 210. The first power line 210 can be connected to a high-voltage power line (VDD) of the display area 100 and configured to transmit a high-voltage signal, for example, a positive voltage signal, to the plurality of sub-pixels P of the display area 100. The first power line 210 is connected to the bonding pads 701 of the binding area 700.
[0050] In an example embodiment, the second peripheral area 300 includes at least a circuit area 301. The circuit area 301 can be disposed on both sides of the display area 100 along the first direction X and connected to the display area 100. The circuit area 301 includes a plurality of driving circuits, for example, gate driving circuits. A plurality of signal transmission lines S1 of the plurality of driving circuits can pass through the fan-out area 400 in a fan-out manner and be connected to the integrated circuit 120, so as to receive signals from the integrated circuit 120 and drive the sub-pixels P.
[0051] With the improvement of the display quality requirement of the display panel, the resolution and refresh rate of the display panel are higher and higher, the number of sub-pixels P of each row of the display area 100 along the first direction X increases, the load of the wire of the driving circuit connected with the row of sub-pixels P increases, the rising edge and falling edge in the pixel charging process increase, which leads to the shortening of the charging time of the pixel and the poor display effect. In the structure shown in FIG. 1, the number of signal transmission lines S1 increases, for example, four clock signal lines are used to provide clock signals for the gate driving circuit. However, in the case that the frame of the display panel is narrowed, the size of the fan-out area 400 along the second direction Y is small, which is not conducive to the arrangement of the wires in the fan-out area 400. As shown in FIG. 1, taking the signal transmission line S1 as the clock signal line as an example, part of the clock signal lines overlap with the first power line 210, and the other part of the clock signal lines do not overlap with the first power line 210. Capacitance will be generated at the overlapping part of the clock signal line and the first power line 210, so that the loads on different clock signal lines are different, which will further lead to different charging times of the pixels by different clock signal lines, and the brightness of the display panel is uneven, especially the brightness difference at low gray scale is obvious.
[0052] The display panel provided by the embodiment of the present disclosure comprises: a display area and a non-display area surrounding the display area, the non-display area comprising a binding area located at one side of the display area and a first peripheral area located between the binding area and the display area; a plurality of sub-pixels located in the display area; a plurality of driving signal lines located in the display area and extending along a first direction, the plurality of driving signal lines being electrically connected with the plurality of sub-pixels; a driving circuit located in the non-display area, the driving circuit being electrically connected with the plurality of driving signal lines; a plurality of data lines located in the display area and extending to the non-display area along a second direction, the plurality of sub-pixels and the plurality of data lines being electrically connected, the first direction and the second direction intersecting; a plurality of first power sub-lines located in the display area and extending along the second direction, the plurality of sub-pixels being electrically connected with the plurality of first power sub-lines; a plurality of binding pads located in the binding area; a first power line located in the non-display area, the first power line being electrically connected with the plurality of first power sub-lines and the binding pads; a plurality of signal transmission lines located at least in the first peripheral area, the plurality of signal transmission lines being electrically connected with the driving circuit; in the direction perpendicular to the display panel, the plurality of signal transmission lines and the first power line overlap with each other; wherein the ratio of the overlapping area of any two of the plurality of signal transmission lines and the first power line is greater than or equal to 0.95 and less than or equal to 1.05.
