Abstract
本发明公开了一种显示面板,其包括:一第一基板;一第二基板,与第一基板相对设置且包括一显示区及一外围区;一封装单元,环设于该第一基板与该第二基板之间,并对应于该显示区的外围;以及多个凸起单元,设于外围区上,且分别具有面向第一基板的一顶面;其中,封装单元具有一沿其长度方向的中心线,在距离中心线的两侧各0μm至200μm的区域内对应设置凸起单元,且在该区域的一单位面积下,顶面的面积总和占单位面积的1%至5%。
Description
技术领域
本发明涉及一种显示面板,特别是一种在基板上设置凸起单元以达到窄边框目的的显示面板。
背景技术
随着显示器技术不断进步,所有的装置均朝体积小、厚度薄、重量轻等趋势发展,故目前市面上主流的显示器装置已由以往的阴极射线管发展成液晶显示设备。特别是,液晶显示设备可应用的领域相当多,举凡日常生活中使用的手机、笔记本电脑、摄影机、照相机、音乐播放器、移动导航装置、电视等显示设备,大多数均使用液晶显示面板。
其中,液晶显示面板的亮度、对比度、色彩、可视角度为决定液晶显示设备观看效果的主要参数。随着液晶显示设备的发展,目前主流或开发中的面板可区分为:扭曲向列型(TN)、垂直配向型(VA)、平面配向型(IPS)等模式。然而,无论是前述何种类型的显示面板,均朝窄边框以使显示区最大化的目标发展。
在常见的液晶显示面板结构中,以配向层帮助液晶倾倒,而可达到快速转换亮暗态的目的。然而,为了符合窄边框的需求,有时会有配向层与胶框交叠的情形,而导致胶框有滑胶、缩胶或断胶的情形,造成显示面板良率降低。
有鉴于此,目前亟需发展一种显示面板,期能解决前述问题并同时达到窄边框的目的。
发明内容
本发明的主要目的在于提供一种显示面板,以便能改善显示面板中封装单元因与配向膜重叠而造成封装单元滑胶、缩胶或断胶的情形。
为达成上述目的,本发明的显示面板包括:一第一基板;一第二基板,与第一基板相对设置且包括一显示区及一外围区;一封装单元,环设于第一基板与第二基板之间,并对应于显示区的外围;以及多个凸起单元,设于第二基板的外围区上,且分别具有面向第一基板的一顶面;其中,封装单元具有一沿其长度方向的中心线,于距离中心线的两侧各0μm至200μm的一区域内对应设置凸起单元,且于该区域的一单位面积下,凸起单元的顶面的面积总和占单位面积的1%至5%。
于本发明的显示面板中,优选为,于距离该中心线的两侧各50μm至200μm的区域内对应设置凸起单元。此外,前述的单位面积可介于2500μm2至40000μm2之间。再者,封装单元的宽度可介于800μm至1000μm之间。再者,封装单元覆盖凸起单元。
于本发明的显示面板中,封装单元可包括多个间隔单元,第二基板的显示区上还设有一配向膜,且凸起单元的高度大于配向膜的厚度且小于间隔单元的粒径。其中,配向膜的厚度可介于0.04μm至0.25μm之间;而间隔单元的粒径可介于2μm至7μm之间。因此,凸起单元的高度优选介于0.2μm至7μm之间。
此外,于本发明的显示面板中,两相邻的凸起单元间的距离大于间隔单元的粒径。优选为,两相邻的凸起单元间的距离为2μm以上。
在此,间隔单元可为一球状间隔单元或一柱状间隔单元。若间隔单元为柱状间隔单元时,粒径则指柱状单元横截面的直径。
再者,于本发明的显示面板中,第一基板及第二基板的其中一者为一上方设置有薄膜晶体管单元的基板,而另一者为一上方设置有彩色滤光单元的基板。或者,第一基板及第二基板的其中一者为一上方同时设置有薄膜晶体管单元及彩色滤光单元的基板。
此外,于本发明的显示面板中,凸起单元的材料并无特殊限制,可为一绝缘材料或一光阻。

具体实施方式
以下通过特定的具体实施例说明本发明的实施方式,本领域的技术人员可由本说明书所披露的内容轻易地了解本发明的其他优点与功效。本发明亦可通过其他不同的具体实施例加以施行或应用,本说明书中的各项细节亦可针对不同观点与应用,在不悖离本发明的精神下进行各种修饰与变更。
图1及图2是分别为本发明一优选实施例的显示面板的上视图及剖面示意图。如图2所示,本实施例的显示面板的制作方法包括:提供一第一基板11及一第二基板12;以及以一封装单元13组设第一基板11及第二基板12。因此,本实施例的显示面板包括:一第一基板11;一第二基板12,与该第一基板11相对设置且包括一显示区A及一外围区B;以及一封装单元13,环设于第一基板11及第二基板12间,并对应于第二基板12的显示区A外围。
在本实施例中,第一基板11及第二基板12间所形成的空间还填充一液晶材料,以作为一液晶显示面板;其中,第一基板11及第二基板12其中一者可为一上方设置有薄膜晶体管单元的薄膜晶体管基板而另一者可为一包括彩色滤光单元及黑色矩阵的彩色滤光基板;或者第一基板11及第二基板12其中一者可为一上方设置有薄膜晶体管单元及彩色滤光单元的阵列上彩色滤光膜(COA)基板而另一者可为一形成有黑色矩阵的基板。此外,在本发明的其他实施例中,第二基板12上也可设置有有机发光单元,以作为一有机发光二极管显示面板。关于前述的第一基板11及第二基板12可具有本技术领域常见的用于液晶显示设备或有机发光二极管装置的基板结构,故在此不再赘述。
图3为本实施例的显示面板的图1区域R的示意图,而图4A则为沿图1剖面线L1-L2的剖面示意图。图3及图4A所示,本实施例的显示面板还包括:多个凸起单元121,设于第二基板11的外围区B上,且分别具有面向第一基板(图未示)的一顶面121a。在本实施例的显示面板的制作过程中,封装单元13沿着一中心线13a进行涂胶,而凸起单元121则设置于距离中心线13a的两侧各0μm至200μm的区域内;且封装单元13的宽度D1介于800μm至1000μm之间。此外,设置有凸起单元121的前述区域一单位面积下,凸起单元121的顶面121a的面积总和占该单位面积的1%至5%。经由涂布封装单元13及将第一基板11及第二基板12组设后,则可得到本实施例的显示面板。因此,通过本发明凸起单元121的设置,且在凸起单元121顶面121a的面积总和占该单位面积的1%至5%的情况下,可有效防止胶框滑胶、缩胶或断胶的情形
如图3所示,在本实施例的显示面板中,封装单元13具有一沿其长度方向的中心线13a,在距离中心线13a的两侧各0μm至200μm的区域内对应设置所述凸起单元121;更具体而言,在距离封装单元13中心线13a两侧的距离D21,D22分别为0μm至200μm所形成的区域内对应设置所述凸起单元121;优选为,在距离封装单元13中心线13a两侧的距离D21,D22分别为50μm至200μm所形成的区域内对应设置所述凸起单元121;最佳为,在距离封装单元13中心线13a两侧的距离D21,D22分别为130μm至180μm所形成的区域内对应设置所述凸起单元121;更佳为,在距离封装单元13中心线13a两侧的距离D21,D22分别约为150μm所形成的区域内对应设置所述凸起单元121。
此外,如图3及图4A所示,在本实施例的显示面板中,在设置有凸起单元121的前述区域的一单位面积下,凸起单元121的顶面121a的面积总和占该单位面积的1%至5%;在此,单位面积介于2500μm2(50μm×50μm)至40000μm2(200μm×200μm)的范围内。在本实施例中,凸起单元121的截面为一梯形;如图4B的图4A凸起单元121的放大图所示,凸起单元121的截面为一梯形,顶面面积即为上底(顶面121a)的面积;然而,本发明并不仅限于此,凸起单元121的截面可具有其他形状,如长方形、正方形等,只要凸起单元121与第一基板(图未示)相对的顶面121a的总面积符合前述范围即可。此外,图4C为本发明的另一优选实施例的凸起单元121的剖面示意图,其中所示的凸起单元121的截面为一弧状;在此情形下,若凸起单元121具有一高度H,则顶面121a面积则为90%高度H(即,高度H’)时所形成的截面的截面面积。
在本实施例中,如图4A所示,封装单元13可包括多个间隔单元131;通过设置此间隔单元131可维持第一基板11及第二基板12间的间距。在此,间隔单元131可分别为一球状间隔单元或一柱状间隔单元。若间隔单元131为球状间隔单元时,则具有一粒径r;而若间隔单元131为柱状间隔单元时,粒径则指柱状单元横截面的直径。
如图3及图4A所示,在本实施例的显示面板中,两相邻的凸起单元121间的距离D大于间隔单元131的粒径r。一般而言,常用的间隔单元131的粒径r介于2μm至7μm之间;故在本实施例中,两相邻的凸起单元121间的距离D可为2μm以上,依所使用的间隔单元131的粒径r而定。
此外,在本实施例的显示面板中,凸起单元121的高度H小于间隔单元131的粒径r。一般而言,常用的间隔单元131的粒径r介于2μm至7μm之间;故在本实施例中,凸起单元121的高度H小于2μm至7μm,依所使用的间隔单元131的粒径r而定。
当本实施例的显示面板为一液晶显示面板(特别是,垂直配向型液晶显示面板)时,第二基板12之上还设有一配向膜,如图5所示。一般而言,配向膜122设置于如图1的显示区A上;然而,为了达到显示区A最大化并使外围区B有窄边框的目的,有时配向膜122亦可能会形成在外围区B上,如图5所示。一般而言,若封装单元13直接设于配向膜上或与配向膜部份重叠时,配向膜将会造成封装单元13有滑胶、缩胶或断胶的情形,而造成显示面板的良率降低。然而,如图5所示,本实施例通过在第二基板11的外围区B上设置凸起单元121,而可固定封装单元13于外围区B上的位置,而改善封装单元13有滑胶、缩胶或断胶的情形,而突破传统产品封装单元13(框胶)不能与配向膜122覆盖的限制,达到窄边框目的,并提高基板利用率。
在本实施例中,如图5所示,为了达到封装单元13覆盖在配向膜122上时不会造成滑胶、缩胶或断胶的情形,凸起单元121的高度H需大于配向膜122的厚度T。一般而言,配向膜122的厚度T介于0.04μm至0.25μm之间;故凸起单元121的高度H大于0.04μm至0.25μm,依所使用的配向膜122的厚度T而定。
图6是本发明另一优选实施例的显示面板的部分剖面示意图。本发明的另一优选实施例的显示面板与前述实施例的显示面板相同,除了前述实施例的显示面板中凸起单元121以一不规则方式排列(如图5所示),而本发明另一优选实施例的显示面板中凸起单元121以规则方式排列(如图6所示)。
图7是本发明再一优选实施例的显示面板示意图。本发明的再一优选实施例的显示面板与前述实施例的显示面板相同,除了前述实施例的显示面板为一方型显示面板,而本发明再一优选实施例的显示面板为一具有圆弧形边框的显示面板。
在本发明前述所有实施例的显示面板中,凸起单元的形成并无特别限制,可使用一绝缘材料与绝缘层一同形成、使用一光阻材料与彩色滤光单元一同形成、或使用一光敏材料与间隔物(photospacer,PS)一同形成。然而,本发明并不仅限于此。
此外,本发明前述实施例所制得的显示面板,可应用于本技术领域已知的任何需要显示屏幕的电子装置上,如显示器、手机、笔记本电脑、摄影机、照相机、音乐播放器、行动导航装置、电视等。
以上所述的具体实施例,对本发明的目的、技术方案和有益效果进行了进一步详细说明,应理解的是,以上所述仅为本发明的具体实施例而已,并不用于限制本发明,凡在本发明的精神和原则之内,所做的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
