以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如[上]、[下 ]、[前]、 [后]、 [左]、 [右]、 [内]、 [外]、 [侧面 ]、[竖直]、[水平]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发明，而非用以限制本发明。在图中，结构相似的单元是用以相同标号表示。
请参照图1至图3所示，本发明提供一种具有照明功能的OLED显示设备1，包括显示区域11、至少一照明区域12及驱动电路16。在本实施例中的OLED显示设备1优选为电视机；在一些另选的实施例中，OLED显示设备1可选为笔记本电脑、平板电脑、监视器或其他应用终端，并不限定。
如图1及图3所示，所述照明区域12包含多个，例如OLED显示设备1的一侧边14、二侧边14、三侧边14或四侧边14，视需要而改变。每一所述照明区域12围设所述显示区域11，且每一所述照明区域12包括排列布设的多个所述有机发光照明装置2。如图2A及图2B所示，OLED显示设备1还包括盖设所述显示区域11和所述至少一照明区域12的保护盖板15，以及设置在所述显示区域11和所述照明区域12之间的所述驱动电路16的线路(图略)。所述保护盖板15设置有遮蔽层13，以遮蔽所述线路。所述遮蔽层13为黑色、白色或其它适合颜色的油墨。在一些另选的实施例中，所述保护盖版15也可以是盖板玻璃、窗口或其他适合的盖板。
所述显示区域11内设置有机发光显示装置2。所述照明区域12邻设于所述显示区域11的一侧边14，其内设置有机发光照明装置3。请一并参照图4所示，所述有机发光显示装置2优选为底发光型白光有机发光显示装置。有机发光显示装置2的基本结构包括在基底21上完成薄膜晶体管器件22(作为驱动电路/开关)后，在源漏极231上设置绝缘层23。
所述绝缘层23上设置有色阻层24，所述色阻层24例如为RGB色阻层或者是RGBW色阻层。在所述色阻层24上依次设置有平坦层25、阳极26、像素限定层27、发光材料层28和阴极29。所述阳极26为透明电极，所述阴极29为反射(金属)电极并形成足以反光的厚度。当所述阳极26及所述阴极29施加信号时，所述发光材料层28会发出光线并透过基底21到达人眼。
请一并参照图5，为绘示本发明有机发光照明装置的第一具体实施例的横截面图。所述有机发光照明装置3包括层叠设置的基底31、绝缘层33、平坦层35、阳极36、发光材料层38和阴极39。驱动电路电性连接所述有机发光照明装置3的所述阳极36和所述阴极39，以控制所述有机发光照明装置3的开启或关闭。因此，本实施例的OLED显示设备1不但具有显示功能，也同样具有照明功能，有助于扩大OLED显示设备1的应用与发展。
具体而言，驱动电路例如为通过与外部信号连接的绑定端子16，例如设置在图3的下侧边14，分别电性连接阳极36及阴极39，并提供驱动信号为发光材料层38供电，即可控制有机发光照明装置3的开启或关闭。然而在如图6所示的第二具体实施例中，有机发光照明装置3内也能够设置薄膜晶体管器件32作为驱动电路/开关，并与图5的阳极36及阴极39电性连接，从而控制照明区域12的开启或关闭。甚至于，驱动电路也可以是有机发光显示装置2内的薄膜晶体管器件22，通过线路电性连接阳极36及阴极39，也能够达到控制照明区域12的开启或关闭的目的。
在如图5及图6所示的实施例中，在此所指的发光材料层38优选为白光器件。此外，如图所示的所述阳极36、所述发光材料层38和所述阴极39的厚度都相同且分别对应设置，使得有机发光照明装置3具有更大的发光面积，而能够发出更大的亮度的白光，从而实现更高亮度的照明。换句话说，在本第一及第二具体实施例中，由于有机发光照明装置3均不设置色阻层(RGBW/RGB)或像素限定层37，使得在所述阳极36、所述发光材料层38和所述阴极39能够具有更大的发光面积，从而使得有机发光照明装置3能够发出更大的亮度的白光。
此外，如图6所述的有机发光照明装置3，还包括依序层叠在基底31上的缓冲层321(buffer layer)、栅极绝缘层322(GI)和层间绝缘层323(ILD)，所述层间绝缘层323设置在所述绝缘层33下方。所述薄膜晶体管器件32设置在所述基底31和所述绝缘层33之间，可作为独立控制本身或是作为控制其他有机发光照明装置3的开启(明)或关闭(暗) ，应用与操控更加简便、灵活。
请一并参照图7及图8所示，为绘示本发明有机发光照明装置的第三及第四具体实施例的横截面图。同理，在本第三及第四具体实施例中，有机发光照明装置3能够依需要选择性的设置像素限定层37，用于限定各子像素区域的透光区和不透光区。此外，图8与图7实施例的差异在于，图8进一步设置有薄膜晶体管器件32作为驱动电路/开关，并与图7的阳极36及阴极39连接，从而控制图7的有机发光照明装置3的开启或关闭。
所述驱动电路除了上述的柔性电路基板上的绑定端子16、薄膜晶体管器件(TFT)外，也可以为栅极驱动电路(Source Driver)、静电放电(Electrostatic Discharge，ESD)电路或阴极输入线电路，并不限定。
需说明的是，设置于任一或多个侧边14的所述有机发光照明装置3可以是与的所述显示区域11连接或是不连接，视需要而改变。此外，所述有机发光照明装置3可以是分别独立设置薄膜晶体管器件32(即驱动电路)控制其开启或关闭，或者是通过一个开关控制多个有机发光照明装置3(即照明区域12)的开启与关闭，视需要而改变。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
