近年来,随着科技的进步,平面液晶显示器逐渐普及化,其具有轻薄等优点。目前平面液晶显示器驱动电路主要是由面板外连接芯片来组成,但是此方法无法将产品的成本降低、也无法使面板更薄型化。
且液晶显示设备中通常具有栅极驱动电路、源极驱动电路和像素阵列。像素阵列中具有多个像素电路,每一个像素电路依据栅极驱动电路提供的扫描讯号开启和关闭,并依据源极驱动电路提供的数据讯号,显示数据画面。以栅极驱动电路来说,栅极驱动电路通常具有多级移位寄存器,并借由一级移位寄存器传递至下一级移位寄存器的方式,来输出扫描讯号到像素阵列中,以依序地开启像素电路,使像素电路接收数据讯号。
因此在驱动电路的制程中,便直接将栅极驱动电路制作在阵列基板上,来取代由外连接IC制作的驱动芯片,此种被称为栅极阵列驱动(Gate On Array,GOA)技术的应用可直接做在面板周围,减少制作程序、降低产品成本且使面板更薄型化。
而曲面型显示面板因其具有更佳的欣赏效果及视觉体验,在近年得到各产商的青睐,但是当GOA技术应用于曲面型显示面板时,随着显示面板的曲面程度不同,设置于显示面板中的主动开关元件亦会有不同程度的形变,影响其结构及性能,进而导致GOA电路在输出时存在一定的差异,伴随出现亮暗线纹的现象,影响产品质量。

以下各实施例的说明是参考附加的图式,用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语,例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等,仅是参考附加图式的方向。因此,使用的方向用语是用以说明及理解本申请,而非用以限制本申请。
附图和说明被认为在本质上是示出性的,而不是限制性的。在图中,结构相似的单元是以相同标号表示。另外,为了理解和便于描述,附图中示出的每个组件的尺寸和厚度是任意示出的,但是本申请不限于此。
在附图中,为了清晰起见,夸大了层、膜、面板、区域等的厚度。在附图中,为了理解和便于描述,夸大了一些层和区域的厚度。将理解的是,当例如层、膜、区域或基底的组件被称作“在”另一组件“上”时,所述组件可以直接在所述另一组件上,或者也可以存在中间组件。
另外,在说明书中,除非明确地描述为相反的,否则词语“包括”将被理解为意指包括所述组件,但是不排除任何其它组件。此外,在说明书中,“在......上”意指位于目标组件上方或者下方,而不意指必须位于基于重力方向的顶部上。
为更进一步阐述本申请为达成预定申请目的所采取的技术手段及功效,以下结合附图及较佳实施例,对依据本申请提出的一种阵列基板及显示面板,其具体实施方式、结构、特征及其功效,详细说明如后。
图1a为一范例性的显示装置示意图。请参照图1a,一种显示装置10,包括一彩色滤光片基板100、一主动阵列基板110及一驱动芯片103,用以驱动电路。
图1b为又一范例性的显示装置示意图。请参照图1b,在本申请一实施例中,一种具有栅极阵列驱动(GOA,Gate on Array)的显示装置11,包括一彩色滤光片基板100、一主动阵列基板110及一栅极阵列驱动105,用以将栅极驱动电路制作在阵列基板110上。

图3为本申请一实施例的主动开关结构示意图,图4为本申请一实施例的阵列基板示意图。请参考图3和图4,在本申请的一实施例中,一种阵列基板,包括:一基板(图未示);多个主动开关(图未示),设置于所述基板上;以及一移位暂存电路300,设置于所述基板上,并位于所述主动开关的侧缘,其中,所述移位暂存电路300具有多级移位寄存器,每一移位寄存器包括:第一开关T10,所述第一开关T10的控制端101a耦接第一节点P1(n),所述第一开关T10的第一端101b耦接频率讯号CK,所述第一开关T10的第二端101c耦接输出脉冲讯号Gn;第二开关T20,所述第二开关T20的控制端201a耦接输入脉冲讯号ST,所述第二开关T20的第一端201b耦接所述输入脉冲讯号ST,所述第二开关T20的第二端201c耦接所述第一节点P1(n);第三开关T30,所述第三开关T30的控制端301a耦接第二节点P2(n),所述第三开关T30的第一端301b耦接所述输出脉冲讯号Gn,所述第三开关T30的第二端301c耦接低预设电位Vss;以及第四开关T40,所述第四开关T40的控制端401a耦接所述第二节点P2(n),所述第四开关T40的第一端401b耦接所述第一节点P1(n),所述第四开关T40的第二端401c耦接所述低预设电位Vss;其中,所述第一开关T10,所述第二开关T20,所述第三开关T30及所述第四开关T40的第一端和第二端的宽度D2均大于所述主动开关的第一端和第二端的宽度D1。
在本申请的一实施例中,更包括一补偿电路,包括:第五开关T50,所述第五开关T50的控制端501a耦接所述输出脉冲讯号Gn,所述第五开关T50的第一端501b耦接所述输出脉冲讯号Gn,所述第五开关的第二端耦接所述低预设电位。
在本申请的一实施例中,所述第五开关T50的第一端和第二端的宽度D2大于所述主动开关的第一端和第二端的宽度D1。
在本申请的一实施例中,所述补偿电路用以降低所述第四开关T40中的控制端401a与第一端401b的电位差。
在本申请的一实施例中,更包括一子下拉电路220,耦接所述第一节点P1(n)、所述输出脉冲讯号Gn及所述低预设电位Vss。
在本申请的一实施例中,更包括一子下拉电路控制器210,耦接所述低预设电位Vss及所述子下拉电路。
请再参考图3,以开关T1作为T10,T20,T30,T40和T50的例示,所述开关T1第一端30b和第二端30c之间的距离的L,其宽度为D2,且大于所述主动开关的第一端和第二端的宽度。于曲面型显示面板中,通过加大开关T1的第一端30b和第二端30c的宽度D2,使第一端30b和第二端30c在控制端30a上的投影面积与主动开关的第一端和第二端的宽度相同或相接近,甚至大于主动开关的宽度,可以使得所述开关T1保持良好电性性能,防止因电性性能不良,导致移位寄存电路失常,以及亮暗线问题的产生。
请同时参考图3和图4,在本申请的一实施例中,一种显示面板,包括第一基板,以及如上所述的阵列基板,与所述第一基板相对设置。其中,所述第一基板及所述阵列基板为柔性基板。

在一些实施例中,本申请的显示面板为曲面型显示面板。
在一些实施例中,通过加大移位寄存电路300的开关的第一端和第二端的宽度D2,使其于曲面型显示面板上,可以克服面板边缘曲率突变所造成的电性不良,提高显示效果和面板质量。
在一些实施例中,本申请的显示面板亦可例如为TN(扭曲向列,Twisted Nematic)、STN(超扭曲向列,Super Twisted Nematic)、OCB(光学补偿弯曲排列,Optically Compensated Birefringence)显示面板,或OLED(有机发光二极管,Organic Light Emitting Diode)显示面板及等离子体显示面板。
本申请通过加大移位寄存电路的开关(T10,T20,T30,T40,T50)的第一端和第二端的宽度D2,且使其于显示面板的不同曲率范围的开关亦有不同宽度的设计,可以解决柔性显示面板因曲率变化导致的开关电性不良,及其所引起的亮暗线问题。
“在一些实施例中”及“在各种实施例中”等用语被重复地使用。所述用语通常不是指相同的实施例;但它也可以是指相同的实施例。“包含”、“具有”及“包括”等用词是同义词,除非其前后文意显示出其它意思。
以上所述,仅是本申请的实施例,并非对本申请作任何形式上的限制,虽然本申请已以具体的实施例揭露如上,然而并非用以限定本申请,任何熟悉本专业的技术人员,在不脱离本申请技术方案范围内,当可利用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例,但凡是未脱离本申请技术方案的内容,依据本申请的技术实质对以上实施例所作的任何简单修改、等同变化与修饰,均仍属于本申请技术方案的范围内。
