Abstract

一种显示装置包含基板、复数个发光件、胶体、光学膜及液晶面板。发光件位于基板的表面上，且发光件之间具有复数个间隙。胶体位于基板的表面上的间隙中，且围绕发光件。光学膜位于胶体与发光件上方。液晶面板位于光学膜上方。胶体可将各个发光件的光源反射出来，进而形成连续的发光区域，以达到光扩散的功能，如此一来，便能避免液晶面板亮度不均匀的状况发生。

Description

显示装置及其制造方法
技术领域
本案是有关于一种显示装置及一种显示装置的制造方法。
背景技术
在显示装置的领域中，次毫米发光二极体(Mini LED)可作为液晶屏幕的背光源。为了增加显示装置的亮度，可采用直下式光源取代侧入式光源。次毫米发光二极体中的发光二极体晶片可藉由荧光粉来转换其发光波长。举例来说，蓝光发光二极体晶片可藉由黄色荧光粉将蓝光与黄光混合成白光。此种结合发光二极体晶片与荧光粉的模块结构之封装方式可分为晶片直接封装(Chip on board,COB)与晶片尺寸封装(Chip size package,CSP)两种。
减小显示装置中的混光距离虽然有助于薄化显示装置，但是，由于混光距离越小，液晶面板对应其下方发光二极体晶片的位置则具有较高的亮度，因此易造成显示面板亮度不均匀的状况发生。
发明内容
本揭露之一技术态样为一种显示装置。
根据本揭露一实施方式，一种显示装置包含基板、复数个发光件、胶体、光学膜及液晶面板。发光件位于基板的表面上，且发光件之间具有复数个间隙。胶体位于基板的表面上的间隙中，且围绕发光件。光学膜位于胶体与发光件上方。液晶面板位于光学膜上方。
在本揭露一实施方式中，光学膜与发光件之间具有介于0mm至1mm范围中的混光距离。
在本揭露一实施方式中，显示装置更包含软性电路板。软性电路板位于基板上且电性连接发光件。
在本揭露一实施方式中，发光件包含发光晶片以及覆盖发光晶片的波长转换层。
在本揭露一实施方式中，波长转换层延伸至发光晶片的侧壁，且位于发光晶片与胶体之间。
在本揭露一实施方式中，胶体包含复数个光学粒子及光学胶，其中光学粒子的材质包含硅或环氧树脂且粒径在5μm至10μm的范围中，且重量百分浓度在25％至30％的范围中，而光学胶的材质包含硅或聚甲基丙烯酸甲酯。
本揭露之一技术态样为一种显示装置的制造方法。
根据本揭露一实施方式，一种显示装置的制造方法包含下列步骤。将复数个光学粒子与光学胶混合，以形成胶体；涂布胶体于基板的表面上的复数个发光件之间的复数个间隙中，使得胶体围绕发光件；设置光学膜于胶体与发光件上方；设置液晶面板于光学膜上方。
在本揭露一实施方式中，更包含封装复数个发光晶片与复数个波长转换层，以形成发光件；并将发光件接合至软性电路板。
在本揭露一实施方式中，光学粒子的材质包含硅或环氧树脂，且光学胶的材质包含硅或聚甲基丙烯酸甲酯。
在本揭露一实施方式中，光学粒子的粒径在5μm至10μm的范围中，且重量百分浓度在25％至30％的范围中。
在本揭露上述实施方式中，由于先将包含硅或环氧树脂等材质的光学粒子与包含硅或聚甲基丙烯酸甲酯的光学胶在合适的比例下均匀混和，以形成具有光扩散功能的胶体。随后，在基板的表面上涂布包含光学粒子的胶体，且使胶体充分填充于发光件之间的间隙中，使得发光件之间无法发光的区域，可藉由填充的胶体而将各个发光件的光源反射出来，而形成连续的发光区域，以达到光扩散的功能。因此当混光距离减小时，仍不会导致因发光晶片的发光范围所对应至液晶面板的区域亮度较高所产生的液晶面板亮度不均匀之状况发生。如此一来，当混光距离减小至介于0mm至1mm的范围中时，仍可保持液晶面板的亮度均匀性，以顺利达成薄化显示装置的目的。

具体实施方式
以下将以图式揭露本揭露之复数个实施方式，为明确说明起见，许多实务上的细节将在以下叙述中一并说明。然而，应了解到，这些实务上的细节不应用以限制本揭露。也就是说，在本揭露部分实施方式中，这些实务上的细节是非必要的。此外，为简化图式起见，一些习知惯用的结构与组件在图式中将以简单示意的方式绘示之。
图1绘示根据本揭露一实施方式之显示装置100的上视图。图2绘示根据本揭露一实施方式之显示装置100沿线段2-2的剖面图。参阅图2，显示装置100包含基板110、复数个发光件130、胶体140、光学膜150及液晶面板160。发光件130位于基板110的表面111上，且相邻的发光件130之间具有复数个间隙W。胶体140位于基板110的表面111上的间隙W中，且围绕发光件130。光学膜150位于发光件130上方。液晶面板160位于光学膜150上方。
在本实施方式中，发光件130为液晶面板160的背光源，例如为直下式光源，发光件130所提供的光线可先后通过光学模150与液晶面板160。在无胶体140的状态下，每一个发光件130所发出的光线均可形成一放射状的发光范围，并且每一个发光件130所形成的发光范围与其相邻的发光件130所形成的发光范围随着光线逐渐远离发光件130而部分重叠。
因此，在无胶体140的状态下，在接近发光件130处存在着两种区域，一种为发光范围无重叠的暗区域，而另一种为发光范围内的重叠的亮区域，此两种区域彼此交错排列。
为了提升显示装置100的亮度均匀性与减少发光件130与光学膜150之间的混光距离d，显示装置100填充胶体140在基板110表面111上的发光件130之间的间隙W中，使得发光件130之间原本无法发光的区域(即间隙W)可藉由填充的胶体140而将各个发光件130的光线往液晶面板160的方向反射，以形成如图2所绘示之连续的发光区域170，进而达到光扩散的功能，并且薄型化显示装置100。
在本实施方式中，透过填充胶体140于发光件130之间的间隙W中，并减小混光距离d至介于0mm至1mm的范围中，可将液晶面板160的亮度均匀性从无填充胶体140的30％提升至填充胶体140后的67％以上。
图3绘示图2之显示装置的局部放大图。如图所示，显示装置100更包含位于基板110上的软性电路板120。软性电路板120电性连接发光件130，以提供线路配置。每一个发光件130均包含了发光晶片132与覆盖于发光晶片132上的波长转换层134。在本实施方式中，基板110可为例如SUS304的金属材质的补强基板，但并不以SUS304为限。在其他实施方式中，基板110可为硬式电路板(PCB)而省略软性电路板120。
在本实施方式中，发光晶片132可为次毫米发光二极体晶片(Mini LED)，例如蓝光发光晶片，其尺寸可在100μm至200μm的范围中，而波长转换层134可为荧光粉，例如黄色荧光粉，但本揭露不以此为限。发光晶片132可藉由波长转换层134来转换其发光波长。于一实施例中，蓝光发光晶片所产生的蓝光可藉由黄色荧光粉转换为白光。而本实施方式是以晶片尺寸封装(Chip size package,CSP)的方式先将发光晶片132与波长转换层134封装后才接合至软性电路板120。基板110、软性电路板120与发光件130可视为灯板。
此外，发光件130的波长转换层134还延伸至发光晶片132的侧壁131，使得波长转换层134的一部分位于发光晶片132与胶体140之间。这样的设计可以使波长转换层134同时与发光晶片132及胶体140接触，以确保由发光晶片132之侧壁131所发出的光会先经由波长转换层134转换波长后，才传递至胶体140扩散。举例来说，从蓝光发光晶片132之侧壁131发射出的蓝光，会先穿过黄色波长转换层134转换为白光后，才进入胶体140进行光扩散。在本实施方式中，胶体140的上表面低于发光件130的上表面，但并不用以限制本揭露。
在本实施方式中，胶体140包含复数个光学粒子142与光学胶144，将光学粒子142与光学胶144以合适的比例均匀混和，使得光学粒子142的重量百分浓度在25％至30％的范围中，如此可让胶体140具有良好的光扩散的功能。光学粒子142可以为包含硅或环氧树脂的材质的微小粒子，且其粒径在5μm至10μm的范围中。光学胶144的材质可以包含硅或聚甲基丙烯酸甲酯(PMMA)，其穿透度可介于95％至99％范围，但并不用以限制本揭露。在其他实施方式中，光学粒子142与光学胶144的材质可以为具有导光特性的各种物质，可依设计者需求而定。
已叙述过的组件连接关系与功效将不再重复赘述，合先叙明。在以下叙述中，将说明显示装置100的制造方法。
图4绘示根据本揭露一实施方式之显示装置100的制造方法的流程图。显示装置100的制造方法包含下列步骤。
在步骤S1中，将复数个光学粒子142与光学胶144混合，以形成胶体140。
在步骤S2中，涂布胶体140于基板110的表面111上的复数个发光件130之间的复数个间隙W中，使得胶体140围绕发光件130。
在步骤S3中，设置光学膜150于胶体140与发光件130上方。
在步骤S4中，设置液晶面板160于150光学膜上方。在以下叙述中，将进一步说明上述各步骤。
在制作图2的显示装置100时，可先提供基板110，并在基板110上方设置具有发光件130的软性电路板120。在本实施方式中，可使用晶片尺寸封装(Chip size package,CSP)的方式先将发光晶片132与波长转换层134封装后，才接合至软性电路板120。其中，基板110、软性电路板120与发光件130可视为灯板。
图5与图6绘示根据本揭露一实施方式之显示装置100的制造方法在特定步骤的示意图。参阅图5，在形成具有基板110、软性电路板120与发光件130的灯板后，可将光学粒子142与光学胶144搅拌混合使其均匀，以形成胶体140。胶体140中的光学粒子142的重量百分浓度可在25％至30％的范围中。
在本实施方式中，光学粒子142可以为包含硅或环氧树脂的材质的微小粒子，且其粒径在5μm至10μm的范围中。光学胶144可包含硅或聚甲基丙烯酸甲酯(PMMA)。在本实施方式中，光学胶144的穿透度可介于95％至99％的范围，但本揭露不以此为限。
参阅图6，在形成图5的胶体140后，可将胶体140涂布于基板110的表面111上的复数个发光件130之间的复数个间隙W中，使得胶体140围绕发光件130，但不覆盖发光件130的上表面。经由以上步骤，便可得到图3的结构。
设置光学膜150于胶体140与发光件130上方，使得光学膜150与发光件130之间具有如图2介于0mm至1mm范围中的混光距离d。设置液晶面板160于150光学膜上方，以形成图2的显示装置100。在本实施方式中的显示装置100可应用于液晶面板相关之产品，如户外显示屏幕、电视、笔记本电脑、桌上显示器、车用显示器、穿戴装置或手机等，但本揭露不以此为限。
由于先将包含硅或环氧树脂等材质的光学粒子142与包含硅或聚甲基丙烯酸甲酯的光学胶144在合适的比例下均匀混和，因此可形成具有良好光扩散功能的胶体140。随后，在基板110的表面111上涂布包含光学粒子142的胶体140，且胶体140填充于发光件130之间的间隙W中，使得发光件130之间无法发光的区域(如间隙W)，可藉由填充的胶体140而将各个发光件130的光源反射出来，以形成连续的发光区域170(见图2)，进而达到光扩散的功能。
虽然本揭露已以实施方式揭露如上，然其并非用以限定本揭露，任何熟习此技艺者，在不脱离本揭露之精神和范围内，当可作各种之更动与润饰，因此本揭露之保护范围当视后附之申请专利范围所界定者为准。
