Description
技术领域 technical field
本发明是有关于一种显示面板,特别是有关于一种可补偿不同长度信号线所造成的影响的显示面板。The present invention relates to a display panel, in particular to a display panel capable of compensating the influence caused by signal lines of different lengths.
背景技术 Background technique
一般而言,平面显示器可分为非自发光显示器以及自发光显示器。液晶显示器(liquid crystal display;LCD)属于非自发光显示器的一种。自发光显示器包含,等离子显示器(plasma display panel;PDP)、场发射显示器(field emissiondisplay;FED)、电致发光(electroluminescent;EL)显示器以及有机发光二极管显示器(organic light emitting diode display;OLED)。In general, flat panel displays can be classified into non-self-luminous displays and self-luminous displays. Liquid crystal display (LCD) is a kind of non-self-luminous display. The self-luminous display includes a plasma display panel (PDP), a field emission display (FED), an electroluminescent (EL) display, and an organic light emitting diode display (OLED).
不论是非自发光显示器以及自发光显示器,其显示面板通常可分为一显示区及一非显示区。如图所示,非显示区110具有至少一驱动电路120。驱动电路120可为一驱动芯片(driving IC)。驱动电路120通过信号线模块130,对显示区140内的像素P11~Pmn进行充电及放电动作。如图所示,信号线模块130是以扇出(fan-out)方式,耦接驱动电路120以及像素P11~Pmn。Whether it is a non-self-luminous display or a self-luminous display, the display panel can generally be divided into a display area and a non-display area. As shown in the figure, the
然而,扇出结构会造成信号线模块130内的信号线长度不一,因而造成像素的充放电速度不一。举例而言,信号线131的长度大于信号线133的长度。因此,当驱动电路120提供相同的信号给信号线131及133时,第一行(垂直方向)的像素P11~P1n的充电/放电速度可能会慢于第三行(垂直方向)的像素P31~P3n的充电/放电速度,因而造成像素P11~P1n所呈现的亮度不同于像素P31~P3n所呈现的亮度。However, the fan-out structure will cause the signal lines in the

When the non-display area further includes an anti-terminal area, the compensation module is disposed in at least one of the display area and the anti-terminal area. When both ends of the signal line extend to the anti-terminal area, the compensation module is arranged in the display area.

具体实施方式 Detailed ways
图2为本发明的显示面板的一可能实施例。如图所示,显示面板200具有一显示区(Active Area;AA)250、一非显示区以及至少一补偿模块(如261~272)。本发明并不限定显示面板200的种类。在一可能实施例中,显示面板200为一液晶显示(LCD)面板。FIG. 2 is a possible embodiment of the display panel of the present invention. As shown in the figure, the
显示区250用以呈现影像,并具有多个信号线以及多个像素。为方便说明,图2仅显示信号线A~D以及像素PA1~PD6。每一像素耦接一相对应的信号线。举例而言,像素PA1~PA6耦接信号线A。由于像素PA1~PD6内的电路结构为本领域人士所深知,故不再赘述。The
在本实施例中,信号线A~D由导电材料所构成,如金属。另外,本发明并不限定信号线的种类。在一可能实施例中,信号线A~D均为扫描电极(scanelectrode),用以传送扫描信号(scan signal)。在其它可能实施例中,信号线A~D可能为数据电极(data electrode)或是共通电极(common electrode),用以传送数据信号(data signal)或是共通电压(common voltage)。In this embodiment, the signal lines A˜D are made of conductive material, such as metal. In addition, the present invention does not limit the types of signal lines. In a possible embodiment, the signal lines AD are all scan electrodes for transmitting scan signals. In other possible embodiments, the signal lines AD may be data electrodes or common electrodes for transmitting data signals or common voltages.
在显示区250以外的区域均称为非显示区。在本实施例中,非显示区包括,近端子区210以及反端子区231~233。近端子区210具有多个信号线,为方便说明,图2仅显示四条信号线A~D。Areas outside the
信号线A~D往显示区250延伸,用以将一驱动电路所提供的驱动信号传送至显示区250内的像素PA1~PD6。在本实施例中,具有将驱动信号由驱动器传入显示区的信号线线段的区域称为此信号线的近端子区(如210),而不具有此类信号线线段的区域称为该信号线的反端子区(如231~233)。The signal lines AD extend to the
近端子区210内的驱动电路211通过近端子区210及显示区250内的信号线A~D,对像素PA1~PD6进行一充放电动作。在本实施例中,是以一芯片玻璃接合技术(Chip On Glass;COG)整合驱动电路211,用以提供驱动信号予信号线A~D,用以对像素PA1~PA6进行充放电动作。在另一可能实施例中,可利用一卷带式自动接合(Tape Automatic Bonding;TAB)以及一芯片软膜接合技术(Chip On Film;COF)整合驱动电路211,用以提供驱动信号予信号线A~D。The driving circuit 211 in the near-
本发明并不限定驱动电路的数量及种类。在一可能实施例中,当信号线A~D为扫描电极时,则驱动电路211为一扫描驱动器(scan driver),用以提供多个扫描信号予像素PA1~PD6,使其开始进行充电或放电动作。在另一可能实施例中,当信号线A~D为数据电极时,则驱动电路211为一数据驱动器(datadriver),用以提供多个数据信号予像素PA1~PD6,使得像素PA1~PD6内的电容器储存相对应的电荷。The invention does not limit the quantity and type of driving circuits. In a possible embodiment, when the signal lines AD are scan electrodes, the driving circuit 211 is a scan driver, which is used to provide a plurality of scan signals to the pixels P A1 -P D6 to start to perform charging or discharging action. In another possible embodiment, when the signal lines AD are data electrodes, the driving circuit 211 is a data driver for providing multiple data signals to the pixels P A1 -P D6 , so that the pixels P A1 The capacitor in ~P D6 stores the corresponding charge.
如果一非显示区域(如区域210)中的信号线线段(如信号线A~D位于区域210中的线段)用以将驱动电路的信号传入显示区(如250)时,则此非显示区称为该信号线的近端子区。如果非显示区(如区域231~233)不包含将驱动信号传入显示区的信号线线段,则统称为该信号线的反端子区。If the signal line segments in a non-display area (such as area 210) (such as the line segments of signal lines A to D located in area 210) are used to transmit the signal of the driving circuit to the display area (such as 250), then this non-display The region is called the near-terminal region of the signal line. If the non-display area (for example, areas 231-233) does not contain the signal line segment that transmits the driving signal to the display area, it is collectively referred to as the anti-terminal area of the signal line.
举例而言,假设一扫描驱动器只从显示区的右侧(如区域231)将扫描信号提供予显示区时,则以扫描电极而言,显示区右侧的非显示区即为扫描电极的近端子区,而不论扫描电极是否由显示区延伸入左侧的非显示区(如区域233),左侧的非显示区都为扫描电极的反端子区。假设采取由显示区两侧将扫描信号提供予显示区的架构,则两侧的非显示区皆为扫描电极的近端子区。For example, assuming that a scan driver only provides scan signals to the display area from the right side of the display area (such as area 231), then in terms of scan electrodes, the non-display area on the right side of the display area is the vicinity of the scan electrodes. The terminal area, regardless of whether the scan electrode extends from the display area to the left non-display area (such as area 233), the left non-display area is the opposite terminal area of the scan electrode. Assuming a structure in which scan signals are provided to the display area from both sides of the display area, the non-display areas on both sides are near terminal areas of the scan electrodes.
同理,假设一数据驱动器只从显示区的上侧(如区域232)将数据信号传入显示区,且一扫描驱动器只从显示区的右侧(如区域231)将扫描信号传入显示区,则显示器上侧的非显示区为数据电极的近端子区,并且为扫描电极的反端子区。同样地,显示器右侧的非显示区为扫描电极的近端子区,并且为数据电极的反端子区。Similarly, assume that a data driver transmits data signals to the display area only from the upper side of the display area (such as area 232), and a scan driver transmits scan signals to the display area only from the right side of the display area (such as area 231). , the non-display area on the upper side of the display is the near-terminal area of the data electrode and the opposite terminal area of the scan electrode. Similarly, the non-display area on the right side of the display is the near-terminal area of the scan electrode and the opposite terminal area of the data electrode.
在本实施例中,信号线A~D是以扇出方式排列,用以将驱动电路211所提供的信号传送给像素PA1~PD6,因此,信号线A~D的长度并不相同(特别是位于近端子区210内的线段长度不相同)。由于信号线A~D的长度将影响像素PA1~PD6的充电放电速度,故为了均匀化每一信号线上的像素的充放电速度,补偿模块261~272耦接相对应的信号线(如A~D),用以补偿信号线A~D的不同长度,对像素的充放电动作所造成的影响。In this embodiment, the signal lines AD are arranged in a fan-out manner to transmit the signals provided by the driving circuit 211 to the pixels P A1 -P D6 , therefore, the lengths of the signal lines AD are not the same ( In particular, the lengths of the line segments located in the near-
在本实施例中,信号线D不具有补偿模块,而信号线A具有补偿模块261~266、信号线B具有补偿模块267~269、信号线C具有补偿模块270~272。由于信号线A~D的长度不同,故针对不同的信号线,需提供不同的补偿程度。举例而言,信号线A的长度短于信号线B,故补偿模块261~266的总补偿程度大于补偿模块267~269的总补偿程度。In this embodiment, the signal line D has no compensation module, but the signal line A has compensation modules 261 - 266 , the signal line B has compensation modules 267 - 269 , and the signal line C has compensation modules 270 - 272 . Since the lengths of the signal lines A to D are different, different compensation levels need to be provided for different signal lines. For example, the length of the signal line A is shorter than that of the signal line B, so the total compensation degree of the compensation modules 261 - 266 is greater than the total compensation degree of the compensation modules 267 - 269 .
本发明并不限定每一信号线上的补偿模块的数量。在一可能实施例中,补偿模块的数量是取决于对应的信号线的长度以及补偿模块的补偿能力。举例而言,当每一补偿模块的补偿能力均相同时,则愈短的信号线需要愈多的补偿模块,或是在较短的信号线中,设置补偿能力较大的补偿模块,而在较长的信号线中,设置补偿能力较小的补偿模块。The present invention does not limit the number of compensation modules on each signal line. In a possible embodiment, the number of compensation modules depends on the length of the corresponding signal lines and the compensation capability of the compensation modules. For example, when the compensation capability of each compensation module is the same, the shorter the signal line, the more compensation modules are required, or in the shorter signal line, a compensation module with a larger compensation capability is set, and in In a longer signal line, a compensation module with a smaller compensation capability is provided.
本发明并不限制补偿模块的设置方式。在一可能实施例中,同一信号线上的每一像素均配置一补偿模块。举例而言,信号线A上的像素P-A1~PA6均配置一补偿模块(如261~266)。在另一可能实施例中,可能每隔N个像素,便配置一补偿模块,如信号线B及C所示。在信号线B为例,每隔1个像素便配置一补偿模块。在其它实施例中,是每隔一固定距离,便设置一补偿模块。The present invention does not limit the arrangement of the compensation module. In a possible embodiment, each pixel on the same signal line is configured with a compensation module. For example, the pixels P- A1 -P A6 on the signal line A are all configured with a compensation module (eg, 261 - 266 ). In another possible embodiment, a compensation module may be configured every N pixels, as shown by the signal lines B and C. Taking the signal line B as an example, a compensation module is configured every other pixel. In other embodiments, a compensation module is provided every fixed distance.
在本实施例中,虽然信号线B及C的补偿模块的数量相同(均具有3个补偿模块),但其补偿能力并不相同。举例而言,由于信号线B的长度短于信号线C的长度,故补偿模块267~269的补偿能力大于补偿模块270~272的补偿能力,方能均匀化信号线B及C的不同长度所造成的影响(充放电速度)。In this embodiment, although the number of compensation modules of the signal lines B and C is the same (both have 3 compensation modules), their compensation capabilities are different. For example, since the length of the signal line B is shorter than the length of the signal line C, the compensation capabilities of the compensation modules 267-269 are greater than the compensation capabilities of the compensation modules 270-272, so that the different lengths of the signal lines B and C can be equalized. The impact (charge and discharge speed).
另外,同一信号线上的补偿模块的补偿能力可能均不相同、均相同或部分相同。在一可能实施例中,同一信号线上的补偿模块的补偿能力可能逐渐降低或是逐渐增加。在另一可能实施例中,愈接近信号线中央的补偿模块的补偿能力愈高。In addition, the compensation capabilities of the compensation modules on the same signal line may be all different, all the same, or partially the same. In a possible embodiment, the compensation capabilities of the compensation modules on the same signal line may decrease or increase gradually. In another possible embodiment, the closer the compensation module is to the center of the signal line, the higher the compensation capability is.
在本实施例中,信号线B及C的补偿模块的数量相同,但不同于耦接到信号线A的补偿模块的数量。在其它实施例中,不同信号线的补偿模块的数量可能均相同、均不同或是一部分相同,其它部分不同。只要适当地调整补偿模块的数量以及补偿模块的补偿能力,便可补偿不同长度的信号线A~D所造成的影响。In this embodiment, the number of compensation modules of the signal lines B and C is the same, but different from the number of compensation modules coupled to the signal line A. In other embodiments, the numbers of the compensation modules of different signal lines may be all the same, all different, or some of them are the same while others are different. As long as the number of compensation modules and the compensation capability of the compensation modules are properly adjusted, the influence caused by the signal lines A to D of different lengths can be compensated.
本发明并不限定补偿模块261~272的结构。在本实施例中,补偿模块261~272分别为电容器CA1~CC6。在一可能实施例中,电容器CA1~CC6可能均为金属绝缘层金属(Metal-Insulator-Metal,MIM)结构或是串接金属绝缘层金属结构(cascade MIM)。在其它可能实施例中,电容器CA1~CC6的部分电容器为MIM结构,而其它电容器为串接MIM结构。The present invention does not limit the structures of the compensation modules 261-272. In this embodiment, the compensation modules 261 - 272 are capacitors C A1 -CC6 respectively. In a possible embodiment, the capacitors C A1 -C C6 may all be Metal-Insulator-Metal (MIM) structures or cascade MIM structures. In other possible embodiments, some capacitors of the capacitors C A1 -C C6 are MIM structures, while other capacitors are series-connected MIM structures.
只要适当地控制每一电容器的金属结构的面积大小,便可适当地控制每一电容器的容值。在本实施例中,每一电容器的金属结构均接收到一电压电位。本发明并不限定电压电位的大小,只要不影响影像品质的电位,均可供给电容器。As long as the area of the metal structure of each capacitor is properly controlled, the capacitance of each capacitor can be properly controlled. In this embodiment, the metal structure of each capacitor receives a voltage potential. The present invention does not limit the magnitude of the voltage potential, as long as the potential does not affect the image quality, it can be supplied to the capacitor.
图3A为本发明的补偿模块的一可能结构示意图。为方便说明,图3A仅显示补偿模块与部分显示区的布局示意图。在本实施例中,信号线A~D分别为数据电极DEA~DED。像素PA1~PD1除了分别耦接数据电极DEA~DED外,更耦接扫描电极SE。由于像素PA1~PD1的结构为本领域人士所深知,故不再赘述。FIG. 3A is a schematic diagram of a possible structure of the compensation module of the present invention. For convenience of description, FIG. 3A only shows a schematic layout of the compensation module and part of the display area. In this embodiment, the signal lines AD are respectively the data electrodes DE A -D D . The pixels P A1 -PD1 are not only coupled to the data electrodes DE A -D D respectively, but also coupled to the scan electrode SE. Since the structures of the pixels P A1 -PD1 are well known by those skilled in the art, details are not repeated here.
如图3A所示,扫描电极SE是朝方向D1延伸,而数据电极DE是朝方向D2延伸,其中方向D1垂直方向D2。扫描电极SE除了往朝方向D1延伸,扫描电极SE更具有一延伸区310A~310C。As shown in FIG. 3A , the scan electrodes SE extend toward a direction D1 , and the data electrodes DE extend toward a direction D2 , wherein the direction D1 is perpendicular to the direction D2 . In addition to extending toward the direction D1, the scan electrode SE further has an extension region 310 A - 310 C .
为了补偿数据电极DEA~DED的不同长度所造成的影响,故延伸区310A~310C是往方向D2延伸,并重叠数据电极DEA~DED。延伸区310A~310C与数据电极DEA~DEC重叠的区域便可定义出电容器CA1、CB1及CC1。In order to compensate the influence caused by the different lengths of the data electrodes DE A ˜ D D , the extension regions 310 A ˜ 310 C extend in the direction D2 and overlap the data electrodes DE A ˜ D D . Capacitors C A1 , C B1 and C C1 can be defined by overlapping regions of the extension regions 310 A ˜ 310 C and the data electrodes DE A ˜ DE C .
借由控制延伸区310A~310C与数据电极DEA~DEC的重叠区域的大小,便可控制电容器CA1、CB1及CC1的容值,进而调整补偿程度。举例而言,延伸区310A与数据电极DEA的重叠区域最大,而延伸区310C与数据电极DEC的重叠区域最小,故电容器CA1的容值大于电容器CC1的容值。因此,电容器CA1的补偿能力大于电容器CC1的补偿能力。By controlling the overlapping areas of the extension regions 310A - 310C and the data electrodes DEA - DEC , the capacitances of the capacitors C A1 , C B1 and C C1 can be controlled, thereby adjusting the compensation degree. For example, the overlapping area between the extension area 310 A and the data electrode DE A is the largest, and the overlapping area between the extension area 310 C and the data electrode DEC is the smallest, so the capacitance of the capacitor C A1 is greater than that of the capacitor C C1 . Therefore, the compensation capability of the capacitor C A1 is greater than that of the capacitor C C1 .
另外,本发明并不限定延伸区310A~310C的形状,以不伤害显示区的开口率(Aperture Ratio)为设计原则。在本实施例中,延伸区310A~310C的形状均相同,是长条形。在其它实施例中,延伸区310A~310C具有不同的形状,并可为任意形状。In addition, the present invention does not limit the shapes of the extension regions 310A - 310C , and the design principle is based on the aperture ratio (Aperture Ratio) that does not damage the display region. In this embodiment, the extension regions 310A - 310C have the same shape and are elongated. In other embodiments, the extension regions 310A - 310C have different shapes, and may be in any shape.
再者,本发明并不限定构成电容器CA1、CB1及CC1的电极种类。为了补偿数据电极DEA~DEC,在本实施例中,电容器CA1、CB1及CC1是由数据电极DEA~DEC与扫描电极SE所构成。在其它可能实施例中,电容器CA1、CB1及CC1可由数据电极DEA~DEC与一补偿电极所构成,其中该补偿电极可为一共通电极或是一额外加入的电极。Furthermore, the present invention does not limit the types of electrodes constituting the capacitors C A1 , C B1 and C C1 . In order to compensate the data electrodes DE A ˜ DEC , in this embodiment, the capacitors C A1 , C B1 and C C1 are formed by the data electrodes DE A ˜ DEC and the scan electrode SE. In other possible embodiments, the capacitors C A1 , C B1 and C C1 may be formed by the data electrodes DE A ˜ DEC and a compensation electrode, wherein the compensation electrode may be a common electrode or an additional electrode.
在一可能实施例中,同一信号线上的补偿电容器可由不同电极层所组成,例如第3A图中电容器CA1中是由数据电极DEA及扫描电极延伸区310A所构成,但与同样用于补偿数据电极DEA的另一电容器(如CA2)则可能位于由共同电极(图未示)和数据电极DEA所构成;而补偿数据电极DEA的另一电容器(如CA3)亦可能由一额外加入的电极和数据电极DEA所构成。In a possible embodiment, the compensation capacitor on the same signal line can be composed of different electrode layers. For example, the capacitor C A1 in Figure 3A is composed of the data electrode DE A and the scanning electrode extension region 310 A , but the same Another capacitor (such as C A2 ) for compensating the data electrode DE A may be formed by a common electrode (not shown) and the data electrode DE A ; and another capacitor (such as C A3 ) for compensating the data electrode DE A is also It may be composed of an additional electrode and data electrode DE A.
在一可能实施例中,该额外加入的电极与扫描电极SE是由同一道制程所形成,并且该额外加入的电极与扫描电极SE具有相同的材质。在另一可能实施例中,该额外加入的电极与像素电极PA1~PD1是由同一道黄光制程所形成,并与像素电极PA1~PD具有相同的材质。In a possible embodiment, the additional electrode and the scan electrode SE are formed by the same process, and the additional electrode and the scan electrode SE have the same material. In another possible embodiment, the additional electrode is formed by the same yellowing process as the pixel electrodes P A1 -PD1 , and has the same material as the pixel electrodes P A1 -PD1 .
本发明并不限定该额外加入的电极的电压电位。该额外加入的电极可能电性连接扫描电极SE,或是接收共通电压(Vcom)、接地电压(GND)及其他可能电压。只要适当地设计电容器CA1、CB1及CC1的大小,便可达到补偿的效果。The present invention does not limit the voltage potential of the additional electrode. The additional electrode may be electrically connected to the scan electrode SE, or receive a common voltage (Vcom), a ground voltage (GND) and other possible voltages. As long as the sizes of the capacitors C A1 , C B1 and C C1 are properly designed, the compensation effect can be achieved.
在其它实施例中,若欲补偿显示区内的扫描电极的不同长度所造成的影响,则电容器可由扫描电极与一补偿电极所构成。本发明并不限定该补偿电极的种类。在一可能实施例中,可利用显示区内已存在的其它电极(如数据电极或共通电极),或是额外加入的导电层构成该补偿电容器。In other embodiments, if it is desired to compensate the influence caused by the different lengths of the scan electrodes in the display area, the capacitor can be formed by the scan electrodes and a compensation electrode. The invention does not limit the type of the compensation electrode. In a possible embodiment, other electrodes (such as data electrodes or common electrodes) existing in the display area, or an additional conductive layer can be used to form the compensation capacitor.
同样地,若欲补偿共通电极的不同长度所造成的影响,则补偿电容器可由一共通电极与一补偿电极(如扫描电极、数据电极或额外新增的电极)所构成。Likewise, if it is desired to compensate the influence caused by the different lengths of the common electrodes, the compensation capacitor can be composed of a common electrode and a compensation electrode (such as a scan electrode, a data electrode or an additional electrode).
虽然电容器CA1、CB1及CC1设置在显示区250之中,然而借由调整重叠区域的大小,便可控制补偿的程度。再者,此电容器的设计可避开开口区(例如设置于面板黑矩阵层下方),因此,并不会对显示面板的开口率造成影响。借由原本的电极(如数据电极、源极电极以及共通电极)形成电容器CA1、CB1及CC1,故可提高电极的使用率,并且不会增加制作成本。Although the capacitors C A1 , C B1 and C C1 are disposed in the
图3B为本发明的补偿模块的另一可能结构示意图。为方便说明,图3B仅显示电容器CA1的结构。在图3A中,电容器CA1是由扫描电极SE的延伸区310A与数据电极DEA所构成。然而,在第3B图中,电容器CA1是由数据电极DEA的一延伸区330A与扫描电极SE所构成。在其它实施例中,亦可利用数据电极DEA的延伸区330A与其它补偿电极(如共通电极或额外加入的电极)构成相对应的补偿装置(如电容)。FIG. 3B is a schematic diagram of another possible structure of the compensation module of the present invention. For convenience of illustration, FIG. 3B only shows the structure of capacitor C A1 . In FIG. 3A, the capacitor C A1 is formed by the extension region 310 A of the scan electrode SE and the data electrode DE A. However, in FIG. 3B, the capacitor C A1 is formed by an extension region 330 A of the data electrode DE A and the scan electrode SE. In other embodiments, the extension region 330 A of the data electrode DE A can also be used to form a corresponding compensation device (such as a capacitor) with other compensation electrodes (such as a common electrode or an additional electrode).
图3C为本发明的补偿模块的另一可能结构示意图。在本实施例中,扫描电极SE与数据电极DEA均具有一延伸区,用以定义出电容器。如图3C所示,扫描电极SE具有一延伸区310A,并且数据电极DEA具有一延伸区330A。电容器CA1形成在延伸区310A与延伸区330A重叠的处。FIG. 3C is a schematic diagram of another possible structure of the compensation module of the present invention. In this embodiment, both the scan electrode SE and the data electrode DE A have an extension area for defining a capacitor. As shown in FIG. 3C , the scan electrode SE has an extension region 310 A , and the data electrode DE A has an extension region 330 A . Capacitor CA1 is formed where extension 310A overlaps extension 330A .
在本实施例中,延伸区310A与延伸区330A的形状及面积相同,但并非用以限制本发明。在其它实施例中,延伸区310A的形状可能不同于延伸区330A的形状,或是延伸区310A的面积可能不同于延伸区330A的面积。In this embodiment, the extension region 310A and the extension region 330A have the same shape and area, but this is not intended to limit the present invention. In other embodiments, the shape of the extension region 310A may be different from that of the extension region 330A , or the area of the extension region 310A may be different from that of the extension region 330A .
图3D为本发明的补偿模块的另一可能结构示意图。在本实施例中,电容器CA1为串接MIM结构。如图所示,电容器CA1是由扫描电极SE的延伸区310A、数据电极DEA以及补偿电极CEA所构成。FIG. 3D is a schematic diagram of another possible structure of the compensation module of the present invention. In this embodiment, the capacitor C A1 is a serial MIM structure. As shown in the figure, the capacitor C A1 is composed of the extension region 310 A of the scan electrode SE, the data electrode DE A and the compensation electrode CE A.
在本实施例中,电容器CA1是位于显示区之中。在另一可能实施例中,电容器CA1可能位于非显示区之中,如在近端子区中或反端子区中。在其它实施例中,电容器CA1的部分位于显示区中,而其它部分位于非显示区中。In this embodiment, the capacitor C A1 is located in the display area. In another possible embodiment, the capacitor C A1 may be located in the non-display area, such as in the near terminal area or in the opposite terminal area. In other embodiments, part of the capacitor C A1 is located in the display area, while the other part is located in the non-display area.
举例而言,延伸区310A与数据电极DEA(或是数据电极DEA与补偿电极CEA)的重叠区域是位于显示区中,而数据电极DEA与补偿电极CEA(或是延伸区310A与数据电极DEA)的重叠区域是位于非显示区中。在其它实施例中,延伸区310A与数据电极DEA(或是数据电极DEA与补偿电极CEA)的部分重叠区域是位于显示区中,而延伸区310A与数据电极DEA(或是数据电极DEA与补偿电极CEA)的其它重叠区域是位于非显示区中。For example, the overlapping area of the extension area 310A and the data electrode DE A (or the data electrode DE A and the compensation electrode CE A ) is located in the display area, and the data electrode DE A and the compensation electrode CE A (or the extension area The overlapping area of 310 A and the data electrode DE A ) is located in the non-display area. In other embodiments, the partial overlapping area between the extension region 310A and the data electrode DE A (or the data electrode DE A and the compensation electrode CE A ) is located in the display region, and the extension region 310A and the data electrode DE A (or The other overlapping area of the data electrode DE A and the compensation electrode CE A is located in the non-display area.
另外,本发明并不限定延伸区310A与数据电极DEA以及数据电极DEA与补偿电极CEA的重叠区域。在一可能实施例中,延伸区310A与数据电极DEA的重叠区域的面积可等于、小于或大于数据电极DEA与补偿电极CEA的重叠区域的面积。In addition, the present invention does not limit the overlapping regions of the extension region 310 A and the data electrode DE A , and the data electrode DE A and the compensation electrode CE A. In a possible embodiment, the area of the overlapping region of the extension region 310 A and the data electrode DE A may be equal to, smaller than or larger than the area of the overlapping region of the data electrode DE A and the compensation electrode CE A.
为了控制补偿电极CEA的电压电位,在本实施例中,补偿电极CEA具有一连接孔(contact hole),用以电性连接扫描电极SE。借由串接MIM(metal insulatormetal)结构,便可在有限的空间中,提高电容器CA1的容值,进而增加补偿能力。In order to control the voltage potential of the compensation electrode CE A , in this embodiment, the compensation electrode CE A has a contact hole for electrically connecting the scan electrode SE. By connecting the MIM (metal insulator metal) structure in series, the capacitance of the capacitor C A1 can be increased in a limited space, thereby increasing the compensation capability.
在一可能实施例中,补偿电极CEA与像素电极PE的材料是属于透明导电氧化物(Transparent Conducting Oxide;TCO)。因此,补偿电极CEA与像素电极PE可由相同的光罩制程所形成,并不需额外增加制程的步骤。In a possible embodiment, materials of the compensation electrode CE A and the pixel electrode PE are transparent conductive oxide (Transparent Conducting Oxide; TCO). Therefore, the compensation electrode CE A and the pixel electrode PE can be formed by the same photomask process without adding additional process steps.
在图3D中,电容器CA1是由扫描电极SE的延伸区310A、数据电极DEA以及补偿电极CEA所构成,但并非用以限制本发明。在其它可能实施例中,电容器CA1是由一第一导电层、一第二导电层以及一第三导电层所构成,此三导电层彼此间以绝缘层隔开,其中该第二导电层为电容器CA1欲补偿的电极,而该第一、第三导电层实质上皆具有补偿电极的功能,并分别位于该第二导电层的第一侧及第二侧。例如在图3D中,数据电极DEA及补偿电极CEA分别位于扫描电极SE的第一侧及第二侧(上、下侧)并都用于补偿扫描电极SE,其中补偿电极CEA、数据电极DEA、扫描电极SE各以绝缘层隔开,而数据电极DEA及补偿电极CEA间经一连接孔电性相连,以改善扫描电极因在近端子区长度不均而造成充电时间不均的问题。In FIG. 3D , the capacitor C A1 is formed by the extension region 310 A of the scan electrode SE, the data electrode DE A and the compensation electrode CE A , but it is not intended to limit the present invention. In other possible embodiments, the capacitor C A1 is composed of a first conductive layer, a second conductive layer and a third conductive layer, and the three conductive layers are separated from each other by an insulating layer, wherein the second conductive layer It is the electrode to be compensated by the capacitor C A1 , and the first and third conductive layers essentially function as compensation electrodes, and are respectively located on the first side and the second side of the second conductive layer. For example, in FIG. 3D, the data electrode DE A and the compensation electrode CE A are located on the first side and the second side (upper and lower sides) of the scan electrode SE respectively and are used to compensate the scan electrode SE, wherein the compensation electrode CE A , the data electrode SE The electrode DE A and the scanning electrode SE are separated by an insulating layer, and the data electrode DE A and the compensation electrode CE A are electrically connected through a connection hole, so as to improve the charging time caused by the uneven length of the scanning electrode near the terminal area. average problem.
举例而言,若电容器CA1欲补偿数据电极的不同长度所造成的影响,则第二导电层为数据电极。同样地,电容器CA1欲补偿扫描电极或共通电极的不同长度所造成的影响,则第二导电层为扫描电极或共通电极。For example, if the capacitor C A1 intends to compensate the influence caused by the different lengths of the data electrodes, the second conductive layer is the data electrodes. Similarly, if the capacitor C A1 is to compensate the influence caused by different lengths of the scanning electrodes or the common electrodes, the second conductive layer is the scanning electrodes or the common electrodes.
在一可能实施例中,第一及第三导电层可能都是额外加入的,或是显示区内不需补偿的电极。举例而言,若欲补偿数据电极,则第一或第三导电层可为显示区内不需补偿的电极(如扫描电极或共通电极),或是额外加入的电极。In a possible embodiment, both the first and the third conductive layers may be additionally added, or electrodes that do not need to be compensated in the display area. For example, if the data electrodes are to be compensated, the first or third conductive layer can be an electrode that does not need to be compensated in the display area (such as a scan electrode or a common electrode), or an additional electrode added.
若使用显示区内的既有电极作为补偿电极,则可增加电极的用途。另外,若借由既有的制程形成额外电极,即可达到补偿效果亦不会增加制程的步骤。举例而言,可在形成扫描电极、数据电极、共通电极、像素电极的同时,一并形成一额外电极,用以补偿一个或多个相对应的电极。If the existing electrodes in the display area are used as compensation electrodes, the usage of the electrodes can be increased. In addition, if the additional electrodes are formed through the existing process, the compensation effect can be achieved without increasing the steps of the process. For example, while forming the scan electrode, the data electrode, the common electrode, and the pixel electrode, an additional electrode can be formed to compensate for one or more corresponding electrodes.
在一可能实施例中,第一及第三导电层其中之一可能是和像素电极由同一道黄光制程所形成。再者,第一及第三导电层其中之一的材料可能和像素电极相同。在其它实施例中,第一及第三导电层可能电性连接到一相同电压源,如共通电压(Vcom)或是接地电压(GND),或是第一至第三导电层彼此电性不相连,其各自接收一相对应电压。In a possible embodiment, one of the first and third conductive layers may be formed by the same process as the pixel electrode. Furthermore, the material of one of the first and third conductive layers may be the same as that of the pixel electrode. In other embodiments, the first and third conductive layers may be electrically connected to the same voltage source, such as a common voltage (Vcom) or a ground voltage (GND), or the first to third conductive layers may not be electrically connected to each other. connected, each of which receives a corresponding voltage.
同样地,第一至第三导电层所构成的电容器可设置在显示区或是非显示区中,如位于近端子区或反端子区中。另外,第一至第三导电层的至少一者的部分电极是位于反端子区之中。举例而言,第一及第二导电层的重叠区域可能位于显示区之中,而第二及第三导电层的重叠区域位于非显示区之中。Likewise, the capacitors formed by the first to third conductive layers can be disposed in the display area or the non-display area, such as in the near-terminal area or in the opposite-terminal area. In addition, part of the electrode of at least one of the first to third conductive layers is located in the anti-terminal region. For example, the overlapping area of the first and second conductive layers may be located in the display area, while the overlapping area of the second and third conductive layers is located in the non-display area.
图4为本发明的显示面板的另一可能实施例。图4相似图2,不同之处在于,图2的补偿模块261~272是设置在显示区250之中,而图4的补偿模块461~463是设置在非显示区的反端子区432之中,并连接对应的信号线A~C的尾端。FIG. 4 is another possible embodiment of the display panel of the present invention. Figure 4 is similar to Figure 2, the difference is that the compensation modules 261-272 in Figure 2 are set in the
在本实施例中,补偿模块461~463分别为电容器CA~CC,其一端分别耦接信号线A~C,另一端接收一电压电位VCM。在一可能实施例中,电压电位VCM与显示区450内的扫描电极的电位相同,但并非用以限制本发明。在其它实施例中,电压电位VCM不同于扫描电极的电位。In this embodiment, the compensation modules 461 - 463 are respectively capacitors CA - CC , one end of which is coupled to the signal lines A - C respectively, and the other end receives a voltage potential V CM . In a possible embodiment, the voltage potential V CM is the same as the potential of the scan electrodes in the
另外,在制作显示区450内的像素电极(如第3D图的PE)的同时,可形成一补偿电极(如第3D图的CEA)。因此,补偿电极的形成并不会增加制造的步骤。在本实施例中,补偿电极与信号线A~C的重叠区域具有电容器461~463。借由控制补偿电极及信号线A~C的电压电位,便可使电容器CA~CC具有补偿的效果。In addition, a compensation electrode (such as CE A in FIG. 3D ) can be formed while forming the pixel electrode (such as PE in FIG. 3D ) in the
当显示区250的空间不足时,亦可将补偿模块461~463设置在反端子区431~433的至少一者中。再者,由于信号线A~D并未延伸至反端子区431~433驱动电路,故显示面板400的可使用的空间较大,可设计容值较大的电容器。When the space of the
本发明并不限定补偿模块的设置位置。在一可能实施例中,不但反端子区432具有补偿模块461~463,连显示区450亦具有补偿模块。另外,若一信号线的两端皆延伸入非显示区,并且和驱动电路相连接(即信号线两侧的非显示区都为近端子区)时,则耦接该信号线的补偿模块便仅设置在显示区450之中。在其它可能实施例中,除了显示区450及反端子区431~433外,补偿模块亦可设置在近端子区410之中。The present invention does not limit the installation position of the compensation module. In a possible embodiment, not only the
由于补偿模块的设置位置相当弹性,故可达到较高的补偿效率,均匀化不同长度的信号线所造成的影响(像素的充电及放电时间)。另外,在其它实施例中,当补偿模块足以均匀化不同长度的信号线所造成的问题时,则信号线可采用片状结构,而不需采用蛇形(z形)结构,故可缩减信号线所占的基板面积,而能窄化近端子区210及410的边框。Since the location of the compensation module is quite flexible, it can achieve higher compensation efficiency and even out the influence (charging and discharging time of pixels) caused by signal lines of different lengths. In addition, in other embodiments, when the compensation module is sufficient to even out the problems caused by signal lines of different lengths, the signal lines can adopt a sheet structure instead of a serpentine (z-shaped) structure, so that the signal line can be reduced. The area of the substrate occupied by the lines can be reduced, and the borders of the near-
