顯示面板以及顯示裝置 Display panel and display device

本申請是有關於一種顯示面板與應用此顯示面板的顯示裝置。 The present application relates to a display panel and a display device to which the display panel is applied.

近年來,光電技術與半導體製造技術之成熟帶動了顯示面板(Display Panel)技術的發展。現有常見的顯示面板包括液晶顯示面板、有機電激發光顯示面板等等。一般而言,顯示面板具有顯示區、位於顯示區之外的外接電路區,以及位於顯示區與外接電路區之間的佈線區。顯示區內具有陣列配置的多個畫素結構,外接電路區內具有電路接點以及可能存在的驅動電路。非顯示區內具有多條導線,用以將畫素結構電性連接至所述驅動電路,或使畫素結構經由電路接點而電性連接至外部電路,以接收顯示時所需的控制訊號與顯示資料。 In recent years, the maturity of optoelectronic technology and semiconductor manufacturing technology has led to the development of display panel technology. Existing common display panels include liquid crystal display panels, organic electroluminescent display panels, and the like. Generally, the display panel has a display area, an external circuit area outside the display area, and a wiring area between the display area and the external circuit area. The display area has a plurality of pixel structures arranged in an array, and the external circuit area has circuit contacts and possible drive circuits. The plurality of wires in the non-display area are used for electrically connecting the pixel structure to the driving circuit, or the pixel structure is electrically connected to the external circuit via the circuit contact to receive the control signal required for display. And display information.

現今的顯示裝置朝向輕薄、窄邊框、高畫質等方向發展,而隨著應用領域的擴展,顯示面板的顯示區域也不限於傳統的矩形。例如,智慧手錶等穿戴式電子裝置的崛起導致了具有圓形或 其他形狀之顯示區域的顯示面板的需求。 Today's display devices are oriented toward thin, narrow bezels, high image quality, etc., and as the field of application expands, the display area of display panels is not limited to conventional rectangles. For example, the rise of wearable electronic devices such as smart watches has led to a round or The display panel needs of display areas of other shapes.

另一方面,為了搭配驅動晶片之接點,傳統設置在非顯示區的導線會排列成扇形結構(fan-out structure),並沿著水平方向與垂直方向彎折延伸。圖1繪示已知的一種顯示面板100,其具有圓形的顯示區域110、位於顯示區110之外的佈線區120,以及最外圍的外接電路區130。此外,請同時參考圖2所示之顯示面板100在佈線區120內的導線佈局,其中顯示區域110內具有多個畫素結構112,多條導線122由非顯示區外圍的外接電路區130(如圖1所示)延伸,通過佈線區120,並連接相應的畫素結構112。圖2中的虛線圓圈190界定為了配置導線122而需使用的最小圓形區域。 On the other hand, in order to match the contacts of the driving wafer, the wires conventionally disposed in the non-display area are arranged in a fan-out structure, and are bent and extended in the horizontal direction and the vertical direction. 1 illustrates a display panel 100 having a circular display area 110, a wiring area 120 outside the display area 110, and an outermost peripheral circuit area 130. In addition, please refer to the layout of the wires in the wiring area 120 of the display panel 100 shown in FIG. 2, wherein the display area 110 has a plurality of pixel structures 112, and the plurality of wires 122 are surrounded by the external circuit area 130 of the periphery of the non-display area ( Extending as shown in FIG. 1 , the wiring area 120 is passed through and the corresponding pixel structure 112 is connected. The dashed circle 190 in Figure 2 defines the smallest circular area to be used in order to configure the wire 122.

由圖2可知,導線122佔用了一定面積的佈線區120。若無法對導線122的佈局做良好的設計,將佔用大面積的佈線區120,從而限制了顯示面板的窄邊框發展,或相對限縮了顯示區110的可用面積。此外,若導線122的長度過長,也將導致導線122本身的阻值過高,而影響訊號傳遞的準確性,例如造成不同導線之信號傳遞的延遲差異。 As can be seen from FIG. 2, the wire 122 occupies a certain area of the wiring area 120. If the layout of the wires 122 cannot be well designed, a large area of the wiring area 120 will be occupied, thereby limiting the development of the narrow frame of the display panel or relatively limiting the available area of the display area 110. In addition, if the length of the wire 122 is too long, the resistance of the wire 122 itself will be too high, which will affect the accuracy of signal transmission, for example, the difference in delay of signal transmission between different wires.

The display panel 300 has a display area 310, a wiring area 320, and an external circuit area 330. Display The display area 310 has a plurality of pixel structures 312 therein.

The pixel structure 312 may include an active element of a liquid crystal display panel, a pixel electrode, a liquid crystal light valve, and a color filter layer, or a cathode of an organic electroluminescence display panel, an organic light-emitting layer, an anode, and the like.

在本實施例中,顯示區310的形狀例如是圓形。然而,在本申請其他未示的實施例中,顯示區310的形狀還可能是其他非矩形的形狀,如橢圓、扇形、蛋形等。此外,所述多個畫素結構312例如是沿水平軸線H與垂直軸線V呈陣列配置。然而,本申請並不限制畫素結構312的排列方式,其可依據實際的設計需求而變更。 In the present embodiment, the shape of the display area 310 is, for example, a circle. However, in other embodiments not shown in the present application, the shape of the display area 310 may also be other non-rectangular shapes such as an ellipse, a sector, an egg, and the like. Further, the plurality of pixel structures 312 are, for example, arranged in an array along the horizontal axis H and the vertical axis V. However, the present application does not limit the arrangement of the pixel structures 312, which may vary depending on actual design requirements.

外接電路區330位於顯示面板300的邊緣,可設置驅動電路或與外部電路連接的電路接點等電子元件。此處不對驅動電路或電路接點等電子元件做詳細描述。本技術領域中具有通常知識者理當能依據現有的技術水準與本申請的揭露,合理推知外接電路區330內可能存在的電子元件的具體結構。 The external circuit area 330 is located at the edge of the display panel 300, and can be provided with electronic components such as a driving circuit or a circuit contact connected to an external circuit. The electronic components such as the driver circuit or circuit contacts are not described in detail here. Those skilled in the art will be able to reasonably infer the specific structure of electronic components that may be present in the external circuit area 330 in accordance with the state of the art and the disclosure of the present application.

佈線區320位於顯示區310與外接電路區330之間。多條導線322穿越佈線區320,用以連接相應的畫素結構312與外接電路區330內的驅動電路或電路接點。更具體而言,每一條導線322包括外引部分372、展開部分374以及內引部分376。外引部分372平行於垂直軸線V,且由外接電路區330延伸至佈線區320。如圖3所示,所述多條導線322的外引部分372沿水平軸線 H並排,展開部分374分別連接相應的外引部分372的末端,並且在佈線區320內扇出。內引部分376連接展開部分374的末端,並且由佈線區320延伸進入顯示區310,以電性連接至所對應的畫素結構312(圖示中為示例,僅繪示連接至部分的畫素結構312)。 The wiring area 320 is located between the display area 310 and the external circuit area 330. A plurality of wires 322 pass through the routing area 320 for connecting the corresponding pixel structure 312 to the driving circuit or circuit contact in the external circuit area 330. More specifically, each of the wires 322 includes an outer lead portion 372, a flared portion 374, and an inner lead portion 376. The lead portion 372 is parallel to the vertical axis V and extends from the external circuit region 330 to the wiring region 320. As shown in FIG. 3, the outer lead portion 372 of the plurality of wires 322 is along a horizontal axis. H is side by side, and the unfolded portion 374 is connected to the ends of the corresponding outer lead portions 372, respectively, and is fanned out in the wiring area 320. The inner lead portion 376 is connected to the end of the unfolding portion 374 and extends from the wiring region 320 into the display region 310 to be electrically connected to the corresponding pixel structure 312 (illustration in the drawing, only the pixels connected to the portion are shown Structure 312).

圖4為圖3之顯示面板300的局部示意圖。請同時參考圖3與圖4,各導線322的展開部分374包括交替連接的多個延伸線段374a以及多個連接線段374b。更具體而言,本實施例的所述多條導線322包括位於垂直軸線V一側且由鄰近垂直軸線V者起算的第1~M條第一導線382,以及位於垂直軸線V另一側且由鄰近垂直軸線V者起算的第1~P條第二導線384。各第一導線382的展開部分374朝向水平軸線H的正軸向延伸,且第N條第一導線382的展開部分374包括交替連接的N個延伸線段374a以及N-1個連接線段374b,1≦N≦M。各第二導線384的展開部分374朝向水平軸線H的負軸向延伸,且第Q條第二導線384的展開部分374包括交替連接的Q個延伸線段374a以及Q-1個連接線段374b,1≦Q≦P。 4 is a partial schematic view of the display panel 300 of FIG. 3. Referring to FIG. 3 and FIG. 4 simultaneously, the unfolded portion 374 of each of the wires 322 includes a plurality of extended line segments 374a and a plurality of connecting line segments 374b that are alternately connected. More specifically, the plurality of wires 322 of the present embodiment include first to M first wires 382 on the side of the vertical axis V and adjacent to the vertical axis V, and on the other side of the vertical axis V and The first to the second second wires 384 from the vertical axis V. The expanded portion 374 of each of the first wires 382 extends toward the positive axis of the horizontal axis H, and the expanded portion 374 of the Nth first wire 382 includes N extended line segments 374a and N-1 connecting line segments 374b, 1 ≦N≦M. The expanded portion 374 of each of the second wires 384 extends toward the negative axial direction of the horizontal axis H, and the expanded portion 374 of the second strip second wire 384 includes Q extended line segments 374a and Q-1 connecting line segments 374b, 1 ≦Q≦P.

各延伸線段374a為平滑連續線段且與水平軸線H夾非零角θ,且各連接線段374b平行於垂直軸線V。在此,延伸線段374a與水平軸線H夾非零角θ的描述可以被解釋為:延伸線段374a與水平軸線H夾零度角之外的各種可能的型態。例如,延伸線段374a是直線線段,且與水平軸線H具有夾角θ;又或者,延伸線段374a是斜率呈連續變化的平滑曲線,而與水平軸線H具有逐漸增加的 夾角θ。由於本實施例的顯示區310為圓形,因此延伸線段374a可以是平行於顯示區310邊緣的圓弧線段。 Each of the extended line segments 374a is a smooth continuous line segment and is non-zero angle θ with the horizontal axis H, and each connecting line segment 374b is parallel to the vertical axis V. Here, the description of the non-zero angle θ between the extended line segment 374a and the horizontal axis H can be interpreted as various possible types of the extended line segment 374a and the horizontal axis H except for the zero degree angle. For example, the extended line segment 374a is a straight line segment and has an angle θ with the horizontal axis H. Alternatively, the extended line segment 374a is a smooth curve in which the slope changes continuously, and has an gradually increasing angle θ with the horizontal axis H. Since the display area 310 of the present embodiment is circular, the extended line segment 374a may be a circular arc segment parallel to the edge of the display area 310.

此外,本實施例可以選擇讓同一條導線322的展開部分374盡量貼近顯示區310的邊緣,以最大程度地節省佈線區320的佈線空間。由於存在多條導線322並排,因此較外側的導線322的展開部分374會超出前一條導線322,以連接較外側的畫素結構312。在此,藉由垂直延伸的連接線段374b連接兩個延伸線段374a,以形成階梯狀的線路結構S,使得超出前一條導線322的延伸線段374a更貼近顯示區310的邊緣。換言之,在同一展開部分374中,較遠離垂直軸線V的延伸線段374a,其與顯示區310邊緣的間距較小,例如圖4所示之不同大小的間距d1與d2。 In addition, the present embodiment can select that the unfolded portion 374 of the same wire 322 is as close as possible to the edge of the display area 310 to maximize the wiring space of the wiring area 320. Since there are a plurality of wires 322 side by side, the flared portion 374 of the outer wire 322 may extend beyond the previous wire 322 to connect the outer pixel structure 312. Here, the two extended line segments 374a are connected by a vertically extending connecting line segment 374b to form a stepped line structure S such that the extended line segment 374a beyond the previous one of the wires 322 is closer to the edge of the display region 310. In other words, in the same unfolded portion 374, the extended line segment 374a, which is farther away from the vertical axis V, has a smaller spacing from the edge of the display area 310, such as the differently sized spacings d1 and d2 shown in FIG.

以下更藉由對照例來說明本實施例之前述佈線結構(trace layout)的技術效果。圖5繪示對照例的佈線結構,其中各導線522的展開部分574由單一圓弧線段所構成,再沿垂直方向延伸進入顯示區510。此種佈線結構導致展開部分574與顯示區510的邊緣之間出現無謂的空白區域B,從而浪費了佈線區520的佈線空間。反觀圖4所示的本申請的實施例,各導線322的展開部分374都盡可能地貼近顯示區310的邊緣,因此能有效利用與節省佈線區320的佈線空間。 The technical effects of the aforementioned trace layout of the present embodiment will be described below by way of a comparative example. 5 shows a wiring structure of a comparative example in which the expanded portion 574 of each of the wires 522 is constituted by a single circular arc segment and extends in the vertical direction into the display region 510. Such a wiring structure causes a unnecessary blank area B to appear between the unfolded portion 574 and the edge of the display area 510, thereby wasting the wiring space of the wiring area 520. In contrast, in the embodiment of the present application shown in FIG. 4, the unfolded portion 374 of each of the wires 322 is as close as possible to the edge of the display region 310, so that the wiring space of the wiring region 320 can be effectively utilized and saved.

此外,如圖4所示,本實施例還可以選擇讓各展開部分374與顯示區310邊緣都維持相同的最小間距d1。任兩相鄰的導線322的展開部分374之間可相互平行,亦即維持相同的間距, 例如前述的最小間距d1。上述做法,不僅可節省佈線區320的佈線空間,也有利於導線322之間的電性設計,避免導線322之間的訊號干擾或其他電性問題。 In addition, as shown in FIG. 4, the embodiment may further select that each of the expanded portion 374 and the edge of the display area 310 maintain the same minimum spacing d1. The unfolded portions 374 of any two adjacent wires 322 may be parallel to each other, that is, maintain the same pitch. For example, the aforementioned minimum spacing d1. The above method can not only save the wiring space of the wiring area 320, but also facilitate the electrical design between the wires 322, and avoid signal interference or other electrical problems between the wires 322.
