技术领域
本公开的实施例涉及光源控制组件、显示装置及制造光源控制组件的方法。
背景技术
在照明、LCD显示背光源、灯箱等场合均会使用各种光源。除了激光外，一般的光源通常为散射型光源，具有较大的发光角度，例如发出的光线在大角度范围内呈均匀分布而发射而没有特定的传播方向。但是，在某些应用场合，只需要利用从光源发出的具有一定方向或在预定发散角范围内传播的光束。例如，在利用LED或OLED等发光单元作为背光源的LCD显示器中，如对光源发出的光线进行控制(例如约束出射光的范围)，由此产生沿预定方向发射的受控光束，以满足特定应用场景如防窥等。
已知一种对LCD显示器的背光源的光线进行控制的方法是利用黑矩阵将从LED或OLED等发光单元发出的预定小角度范围以外的、不需要的大角度光吸收，而只允许从LED或OLED等发光单元发出的预定小角度范围内的光线沿大致一致的方向射向LCD显示面板以作为显示光源，从而满足特定应用场景如防窥等。但是，由于这种方法对光的利用率较低，导致从发光单元发出的大部分大角度出射光不能被有效利用，从而想要获得需要的显示亮度就需要更高的功耗。

根据本公开实施例的总体发明构思，提供一种光源控制组件，包括：光电转换器；多个发光单元，每个发光单元适于通过接收电能来发射光；和光控制结构，其中，所述光控制结构构造成使得从所述至少一个发光单元中各个发光单元发出的一部分光通过、且阻挡从所述至少一个发光单元中各个发光单元发射的另一部分光，来利用穿过所述光控制结构的所述一部分光生成彼此分离的多个受控光束，而从各个发光单元发 出的另一部分光被光电转换器接收。根据本公开的光源控制组件，能够利用光电转换器来回收利用不能用于产生受控光束的其它光线，从而提高了光利用率。
具体地，所述光电转换器例如是太阳能电池板，所述太阳能电池接收发光单元发出不用于产生受控光束的大角度光，且这部分大角度光的光能被转换为电能给发光单元供电。以下以太阳能电池板为例来说明本公开的示例性实施例。
图1是根据本公开的一个示例性实施例的光源控制组件100的简化结构图。如图1所示，光源控制组件100包括太阳能电池板1；设置在太阳能电池板1上的至少一个发光单元2。图1示出了多个发光单元2的情况。多个发光单元2从电源接收电能以发出束状光线L。所述光源控制组件100还包括与太阳能电池板1相对设置的盖板3，所述盖板3设置于所述多个发光单元2的背离太阳能电池板1的一侧上方且与所述多个发光单元2间隔开，并且包括多个的透光部分31和多个光反射部分32。所述多个透光部分31分别与所述多个发光单元2的位置对准，使得从各个发光单元2发射的不超过预定发散角α范围的光线分别从所述多个透光部分31传播而射出；所述多个光反射部分32构成阻光部分，使得从各个发光单元2发射的超过预定发散角α范围的光线被太阳能电池板1再次吸收而利用以产生电能。在其他实施例中，上述太阳能电池板1产生的电能例如作为辅助电源，向发光电源2供电，也例如用作其他的用途。
根据一个具体的例子，多个透光部分31分别与所述多个发光单元2的位置对准的状态包括：每个发光单元2的朝向盖板3的垂直投影落在与其对准设置的一个透光部分31的中心位置。
具体地，所述多个光反射部分32将从各个发光单元2发射的超过预定发散角α范围的光线朝向太阳能电池板1反射，以被太阳能电池板1再次吸收而利用以产生电能。进而，所产生的电能再次输入发光单元2以使发光单元2发出光线。本领域技术人员例如根据所希望的对于受控光的控制程度确定预定发散角的具体角度。例如，预定发散角α例如选择为5°。
在上述实施例中，所述发光单元2例如是普通LED光源，或者OLED光源。另外，所述发光单元2例如是点光源，也替代地例如是线性光源。在点光源的情况下，通过本公开实施例的光源控制组件例如提供在点光源周围的各个方向上发散角在预定范围内的受控的点状光束，以满足各种需要点状光束的应用场合。在线性光源的情况下，通过本公开实施例的光源控制组件例如提供在线性光源的宽度方向上发散角在预定范围内的受控的线状光束，以满足各种需要线状光束的应用场合。
作为示例性实施例，所述太阳能电池板1例如是不透光的硅薄膜太阳能电池、铜铟镓硒薄膜太阳能电池，聚合物太阳能电池等，其结构和制备方法与常规太阳能电池相同。
图2示出了图1所示的光源控制组件100的一个示例性具体结构的示意图。如图2所示，发光单元2采用OLED光源。所述OLED光源包括层叠布置的阳极21、有机发光层22和阴极23。阳极21例如采用透明氧化铟锡(ITO)材料制备。有机发光层22具体例如包括空穴注入层、空穴传输层、发光层、电子传输层、电子注入层等。阴极23例如是透明材料的导电层。阳极21和有机发光层22各自包括多个独立的且间隔开布置的单元结构，阴极23例如如图所示为整块阴极的形式。在替代的实施例中，所示阴极还可构造成与所述阳极21和有机发光层22呈分别对齐呈多个独立且间隔开地布置。
这里，每个阳极单元和其上的每个有机发光层单元以及对应的阴极部分构成一个OLED发光单元，用于接收从太阳能电池板1提供的电能以发光。太阳能电池板1采用整块太阳能电池板的形式，具体包括层叠布置的下电极11、PN结12和上电极13。太阳能电池板1和OLED发光单元之间例如设置绝缘的钝化层4。OLED发光单元的阳极21和阴极23例如与太阳能电池板1的下电极11和上电极13分别电连接，以接收从太阳能电池板1提供的电能。虽然图中没有示出，能够理解，除了太阳能电池板1以外，光源控制组件100还例如包括其它的电源，用于对OLED单元提供电能。本公开对此不作限定。
如图2所示，光源控制组件100还包括例如玻璃制成的基板5，太阳能电池板2形成在所述基板5上。盖板3与基板5相对，其间用间隔件6支撑，以在盖板3与基板5二者之间形成被构造用以容纳OLED发光单元2和太阳能电池1的空间。间隔件5例如是UV固化胶。
注意，图2只是示意地示出了根据本公开的一个实施例的光源控制组件100的结构，为了清楚起见，只对与本公开的发明主题有关的结构进行了图示，而省略了其它一些已知的结构。本领域技术人员应当理解，本实施例的光源控制组件100还例如包括常规OLED光源的其它必要组成元件，太阳能电池板1也例如包括常规太阳能电池板的其它必要组成元件，在此不再赘述。
如图2所示，根据一个实施例，盖板3例如是透明的玻璃盖板，所述多个光反射部分32例如由形成在透明盖板3的面对太阳能电池板1的一个表面上的且间隔开布置 的多个光反射元件33构成，而所述多个透光部分31由透明盖板3的除所述多个反射元件33以外的部分、和/或形成于所述透明盖板上的通孔构成，即所述多个透光部分31彼此之间被所述多个光反射元件33分隔开。此处，盖板3构成光控制结构，透光部分31用于透过大致受控的光，光反射部分32用于反射大角度光。本公开的光控制结构不限于此，本领域技术人员例如设想其它能够形成透光部分和阻光部分的光控制结构。
作为替代实施例，所述盖板3也例如为不透明盖板，所述多个光反射部分32也例如包括设置在透明盖板的面对所述光电转换器的一个表面上的多个光反射元件33，所述多个透光部分31包括形成于所述不透明盖板上的通孔。
图3是图2所示的光源控制组件的盖板3的平面示意图。参见图1和3，在发光单元2形成点光源时，所述盖板3的透光部分31相应地形成圆形形状。每个发光单元2在盖板3上的垂直投影落入对应的透光部分31的中心位置。如图1所示，从发光单元2到盖板3的距离为Y，则透光部分31的半径R＝Y*tgα，其中α是所述预定发散角。
因此，本领域技术人员例如根据所希望的受控光的预定发散角α来设定透光部分的半径R和发光单元与盖板的距离Y。例如，预定发散角α例如大于等于1°且小于等于10°。
例如，若预定发散角α选择为5°，则tg5°≈0.87，则R/Y＝0.87，其中R为圆形透光部分31的半径，Y为发光单元2距离盖板3的高度。例如，R为5um，则Y应当为大约5.75um。
另外，根据一些实施例，每个发光单元2的最大光发射角度表示为β，光反射部分32例如包括围绕圆形透光部分31的环形部分。在这种情况下，所述环形部分的沿径向方向的宽度至少为Z1＝Y*tgβ-R。这样，从发光单元2发出的除预定发散角以内的用于产生受控光的光线以外的光线，即发射角介于α和β之间的大角度光线例如全部被呈所述环形部分的光反射部分32反射回到太阳能电池板1，以被太阳能电池板1再次利用而产生电能，所述电能继而施加至OLED发光单元2以发光，从而，该实施例的光源控制组件提高了光利用率，降低了功耗。
因此，本领域技术人员例如根据具体发光单元的最大发光角度β、发光单元和盖板的距离Y以及透光部分的半径R来设定光反射部分的尺寸。例如，最大发光角度β例如大于等于50°且小于等于70°。
例如，通过实验得知，通常OLED发光单元的最大发光角度β大约为60°，因此例如按最大发光角度60°进行器件尺寸设计。例如，若要求受控光具有5°以内的预定发散角，则tg5°＝R/Y，则R≈0.87y；tg60°＝(R+Z1)/Y，则Z1≈1.645Y。例如R为5um，则Y应当为大约5.75um，Z1应当为大约9.46um。
注意，为了清楚起见，图1-3不一定按比例绘制。另外，虽然图3示出了光反射部分32为围绕圆形透光部分31的环形部分，但是为了便于制造，光反射部分32例如包括除圆形透光部分31以外的盖板3的全部剩余部分。
以上的实施例示例地说明了发光单元为点光源的情况，通过该实施例的光源控制组件例如提供在点光源周围的各个方向上发散角在预定范围内的受控的点状光束，以满足各种需要点状光束的应用场合。
以下说明制造图1-3所示的实施例的光源控制组件100的方法。
首先，提供基板，例如玻璃基板；
接着，在基板上制作整块的太阳能电池板，所述太阳能电池板包括下电极、PN结和上电极。太阳能电池板例如是不透光的硅薄膜太阳能电池、铜铟镓硒薄膜太阳能电池，聚合物太阳能电池等，制备方法如常规工艺，在此不再赘述。
接着，例如在太阳能电池板的上电极上沉积一层绝缘钝化膜；并在太阳能电池板的上电极上方的钝化膜上制备OLED点阵光源，OLED点阵光源例如利用精细掩膜版依次沉积ITO阳极层、空穴注入层、空穴传输层、发光层、电子传输层、电子注入层以及阴极层而形成。并且，通过制作例如过孔使得每个OLED发光单元的阳极和阴极分别与太阳能电池板的上电极和下电极电连接，以使得所述多个发光单元从太阳能电池板接收电能以发光；
接着，通过UV固化胶等连接盖板和基板。所述盖板例如预先制成为包括多个透光部分和作为阻光部分的多个光反射部分。在进一步的实施例中，所述多个光反射元件例如是涂覆在所述盖板的面对所述光电转换器的一个表面上的多个光反射涂层。具体地，例如提供透明盖板，并在透明盖板的将面对太阳能电池板而布置的一个表面上沉积例如金属反射膜，以形成多个光反射部分，其余部分则形成为透光部分。连接盖板和基板时，使多个透光部分分别与多个发光单元的位置对准。例如，例如使每个发光单元2在盖板3上的垂直投影落入对准设置的透光部分31的中心位置。
制作和连接盖板时，如前参照图1和3所示，如发光单元为点光源，例如根据所希望的受控光的预定发散角α来设定圆形透光部分的半径R和发光单元与盖板的距离 Y；并根据具体发光单元的最大发光角度β、发光单元和盖板的距离Y以及透光部分的半径R来设定光反射部分的尺寸。
如此制成的盖板，所述多个透光部分构造成分别与所述多个发光单元的位置对准，使得从各个发光单元发射的不超过预定发散角的光线分别从所述多个透光部分射出以作为受控光被使用；而所述多个光反射部分构造成分别将从各个发光单元发射的超过预定发散角的光线朝向太阳能电池板反射，以被太阳能电池板再次利用以产生电能，该电能又可提供给发光单元以产生光。
上述实施例的光源控制组件及其制作方法，由于在光源控制组件中包括了太阳能电池，并利用太阳能电池接收从发光单元发出的不用于产生受控光的大角度光，将这部分光能转换为电能给发光单元供电，从而，提高了光源控制组件的光利用率，减少了发光单元的功耗，同时获得了所需的受控光束。
图4是根据本公开的另一个实施例的光源控制组件200的简化结构图。如图4所示，光源控制组件200包括基板50；设置在基板50上的间隔开布置的多个发光单元20；以及与基板50相对设置的盖板30。盖板30与基板50之间用间隔件60支撑，以形成容纳OLED发光单元20的空间。间隔件60例如是导电胶。
该实施例的盖板30包括多个透光部分31和多个光电转换器10(例如多个太阳能电池板10)。所述多个透光部分31与图1的实施例一样分别与所述多个发光单元20的位置对准，使得从各个发光单元20发射的不超过预定发散角α范围的光线分别从所述多个透光部分31射出，作为受控光；例如，每个发光单元2在盖板3上的垂直投影落入对准设置的透光部分31的中心位置。所述多个太阳能电池板10分别构成阻光部分，以使得从各个发光单元20发射的超过预定发散角α范围的光线被太阳能电池板10再次利用以产生电能。
具体地，所述多个太阳能电池板10构造成直接吸收从各个发光单元发射的超过预定发散角α范围的光线，并进行光电转换以产生电能。之后，所产生的电能例如通过电连接元件输送到发光单元20，用于使发光单元20发光。
在上述实施例中，所述发光单元20例如是普通LED光源，或者OLED光源。另外，所述发光单元20例如是点光源，也例如是线性光源。所述太阳能电池板10例如是不透光的硅薄膜太阳能电池、铜铟镓硒薄膜太阳能电池，聚合物太阳能电池等，其结构和制备方法与常规太阳能电池相同。所述基板50例如是玻璃基板。
作为替代实施例，图5示出了图4所示的光源控制组件200的一个示例性具体结 构的示意图。如图4所示，发光单元20采用OLED光源。所述OLED光源包括阳极21、有机发光层22和阴极23。阳极21可采用透明氧化铟锡(ITO)材料制备。有机发光层22具体例如包括空穴注入层、空穴传输层、发光层、电子传输层、电子注入层等。阴极23可为透明材料的导电层。阳极21和有机发光层22分别包括多个独立且间隔开布置的单元结构，阴极23例如如图所示为整块阴极的形式。在替代的实施例中，所示阴极还可构造成与所述阳极21和有机发光层22呈分别对齐呈多个独立且间隔开地布置。
这里，每个阳极单元和其上的每个有机发光层单元以及对准设置的阴极部分构成一个OLED发光单元20，用于从太阳能电池板10接收电能以发光。每个太阳能电池板10具体包括下电极11、PN结12和上电极13。太阳能电池板10的下电极11和上电极13例如通过引线70、导电的间隔件60、过孔等分别电连接至OLED发光单元20的阳极21和阴极23，以将太阳能电池板10的电能输送给OLED发光单元20。OLED发光单元20从太阳能电池板10接收电能以发光。虽然图中没有示出，能够理解到，除了太阳能电池板10以外，光源控制组件200还例如包括其它的电源，用于对OLED单元提供电能。本公开对此不作限定。实质上，与之前图2所示的光源控制组件100相比，光源控制组件200的不同之处在于，所述多个太阳能电池板10，即下电极11、PN结12和上电极13，被设置到与基板50相对设置的盖板30的与基板面对的一侧上，而非如图2所示直接设置在基板50上的与盖板30面对的一侧上。
注意，图5只是示意地示出了根据本公开的一个实施例的光源控制组件200的结构，为了清楚起见，只对与本公开的发明主题有关的结构进行了图示，而省略了其它一些已知的结构。本领域技术人员应当理解，本实施例的光源控制组件200还例如包括常规OLED光源的其它必要组成元件，太阳能电池板10也例如包括常规太阳能电池板的其它必要组成元件，在此不再赘述。另外，为了清楚起见，图5不一定按比例绘制。
如图4所示，根据一个实施例，盖板30例如是透明的玻璃盖板，所述多个太阳能电池板10由形成在透明盖板30的面对基板50的一个表面上的薄膜电池构成，所述多个透光部分31由透明盖板30的除所述多个太阳能电池板10以外的部分构成。此处，盖板30构成光控制结构，透光部分31用于透过大致被控制的光，太阳能电池板10用于吸收大角度光。本公开的光控制结构不限于此，本领域技术人员例如设想其它能够形成透光部分和阻光部分的光控制结构。
作为替代实施例，所述盖板30也例如为不透明盖板，所述多个光电转换器10被形成在透明盖板的面对所述基板30的一个表面上，所述多个透光部分31包括形成于所述不透明盖板30上的通孔。
图6是图5所示的光源控制组件的盖板30的一个示例平面示意图。参见图4和6，在发光单元20形成线性光源时，所述盖板30的透光部分31相应地形成条状。如图4和6所示，从发光单元20到盖板30的距离为Y，则条状的透光部分31的宽度X＝2Y*tgα，其中α是预定发散角。
因此，本领域技术人员例如根据所希望的受控光的预定发散角α来设定透光部分的宽度X和发光单元与盖板的距离Y。例如，预定发散角α例如在1-10度的范围内选择。
例如，若预定发散角α选择为5°，则tg5°≈0.87，则X/2Y≈0.87，其中X为条状透光部分31的宽度，Y为发光单元2距离盖板3的高度。例如，X为10um，则Y应当为大约5.75um。
另外，根据一些实施例，每个发光单元20的最大光发射角度表示为β，构成阻光部分的每个太阳能电池板10例如包括与透光部分31的每一侧相邻的条状部分。在这种情况下，所述条状部分的宽度Z2至少为Z2＝Y*tgβ-X/2。这样，从发光单元20发出的除预定发散角以内的用于产生受控光的光线以外的光线L，即发射角介于α和β之间的大角度光线例如全部被太阳能电池板10吸收，从而被太阳能电池板10再次利用而产生电能，所述电能可通过电连接单元施加至OLED发光单元20以使其发光。因此，该实施例的光源控制组件提高了光利用率，降低了功耗。
因此，本领域技术人员例如根据具体发光单元的最大发光角度β、发光单元和盖板的距离Y以及透光部分的宽度X来设定太阳能电池板10的尺寸。通常，最大发光角度β例如在50-70度的范围内选择。
例如，通过实验可知，通常OLED发光单元的最大发光角度β为60°，因此例如按最大发光角度60°进行器件尺寸设计。例如，若要求受控光具有5°以内的预定发散角，则tg5°＝X/2Y，则X/2≈0.87y；tg60°＝(X/2+Z2)/Y，则Z2≈1.645Y。例如，X为10um，则Y为大约5.75um，Z2为大约9.46um。
以上的实施例示例地说明了发光单元为线性光源的情况，通过该实施例的光源控制组件例如提供在线性光源的宽度方向上发散角在预定范围内的受控的线状光束，以满足各种需要线状光束的应用场合。
以下说明制造图4-6所示的实施例的光源控制组件200的方法。
首先，提供基板，例如玻璃基板；
接着，在基板上制备OLED点阵光源，OLED点阵光源例如利用精细掩膜版依次沉积ITO阳极层、空穴注入层、空穴传输层、发光层、电子传输层、电子注入层以及阴极层而形成；
然后，通过例如导电胶连接盖板。所述盖板例如预先制成为包括多个透光部分和作为阻光部分的多个太阳能电池板的结构。在进一步的实施例中，所述多个光反射元件例如是涂覆在所述透明盖板的面对所述光电转换器的一个表面上的多个光反射涂层。具体地，例如提供透明盖板，并在透明盖板的将面对太阳能电池板的一个表面上制备薄膜太阳能电池，作为阻光部分，其余部分则形成为透光部分。连接盖板时，使多个透光部分分别与多个发光单元的位置对准。具体地，例如使每个线性的发光单元2在盖板3上的垂直投影落入对准设置的条状的透光部分31的中心位置(宽度方向)。在制作盖板时，例如在太阳能电池板上制作引线、过孔等，使得盖板被连接后，通过引线、过孔、导电胶等将太阳能电池板的电能输送至发光单元，使发光单元产生光。
制作和连接盖板时，如前参照图4和6所示，如发光单元为线性光源，例如根据所希望的受控光的预定发散角α来设定条状透光部分的宽度X和发光单元与盖板的距离Y；并根据具体发光单元的最大发光角度β、发光单元和盖板的距离Y以及透光部分的宽度X来设定太阳能电池板的尺寸。
如此制成的盖板，所述多个透光部分构造成分别与所述多个发光单元的位置对准，使得从各个发光单元发射的不超过预定发散角范围的光线分别从所述多个透光部分射出以作为受控光被使用；而所述多个太阳能电池板则构造成分别接收从各个发光单元发射的超过预定发散角范围的光线以产生电能，该电能又可提供给发光单元以产生光。
上述实施例的光源控制组件及其制作方法，类似于图1-3的实施例，由于在光源控制组件中包括了太阳能电池，并利用太阳能电池吸收从发光单元发出的不用于产生受控光的大角度光，将这部分光能转换为电能给发光单元供电，从而，提高了光源控制组件的光利用率，减少了发光单元的功耗，同时获得了想要的受控光束。
综上所述，本公开的各示例性实施例提供了一种光源控制组件，包括太阳能电池板；多个发光单元，所述多个发光单元构造成接收电能以发光；和位于多个发光单元的出光方向上的光控制结构，其中，所述光控制结构包括多个透光部分和多个阻光部分，所述多个透光部分构造成使得从各个发光单元发射的不超过预定发散角的光线分 别从所述多个透光部分射出；所述多个阻光部分构造成使得从各个发光单元发射的超过预定发散角的光线被太阳能电池板接收以产生电能。
因此，本申请的各实施例将控制光源中不需要的大角度的光，转化为太阳能电池的电能，该电能例如进一步给OLED发光单元供电，从而增加了光的利用效率，同时获得需要的受控光束。
根据本公开另一方面的实施例，如图7所示，提供了一种显示装置，包括：显示面板300；和背光源，所述背光源包括如前述实施例的光源控制组件100或200，其具体结构在此不再赘述。
具体地，如图7所示，所述显示面板300例如是LCD面板，所述LCD面板包括彩膜层301、阵列基板302和介于彩膜层与阵列基板之间的液晶层303。本领域技术人员应当理解，显示面板300还例如包括偏振片、取向膜、扩散膜等其它公知的结构，在此不再赘述。
由于采用了如前述实施例的光源控制组件，本实施例的显示装置的背光源具有较低的功耗，光利用率高，同时获得受控光束，用于LCD显示面板以作为显示光源，从而满足特定应用场景如防窥等。
根据本申请的光源控制组件、显示装置和制造光源控制组件的方法，通过光电转换器来回收利用不能用于产生受控光束的其它光线，从而减少了发光单元的光损失，增加了光的利用效率，同时能够获得需要的受控光束。
虽然以上参照附图描述了本公开的一些具体实施例，本领域技术人员应当理解，在不引起冲突的情况下，各施例的光源控制组件的组成部分相互组合或替代。例如，虽然图1-3的实施例采用了点光源，相应地，盖板采用圆形透光部分和环形阻光部分；但是，图1-3的实施例也例如采用线性光源，相应地，盖板例如采用条状透光部分和条状阻光部分。类似地，虽然图4-6的实施例采用了线性光源，相应地，盖板采用条状透光部分和条状阻光部分；但是，图4-6的实施例也例如采用点光源，相应地，盖板例如采用圆形透光部分和环形阻光部分。
另外，虽然以上的实施例以太阳能电池板作为光电转换器的例子，但本领域技术人员能够理解到，其它的光电转换器可用于代替太阳能电池板，只要其能够回收利用不能用于产生受控光束的大角度光线以提高光利用率即可。
本领域的技术人员能够理解到，上面所描述的实施例都是示例性的，并且本领域的技术人员可以对其进行改进，各种实施例中所描述的结构在不发生结构或者原理方面的冲突的情况下可以进行自由组合。
虽然结合附图对本公开进行了说明，但是附图中公开的实施例旨在对本公开优选实施方式进行示例性说明，而不能理解为对本公开的一种限制。
虽然本总体发明构思的一些实施例已被显示和说明，本领域普通技术人员将理解，在不背离本总体发明构思的原则和精神的情况下，可对这些实施例做出改动和变型，这些改动和变型都应涵盖在本公开的保护范围之内。本公开的保护范围以所附权利要求和它们的等同物限定的保护范围为准。
