为使本公开实施例的目的、 技术方案和优点更加清楚, 下面将结合本公 开实施例的附图, 对本公开实施例的技术方案进行清楚、 完整地描述。显然, 所描述的实施例是本公开的一部分实施例, 而不是全部的实施例。 基于所描 述的本公开的实施例, 本领域普通技术人员在无需创造性劳动的前提下所获 得的所有其他实施例, 都属于本公开保护的范围。
在图 1所示的液晶显示面板中, 由于光源 201设置在背光模块 200的左 右两侧中至少一侧, 使得背光模块的体积较大, 不利于显示器的轻薄化。
本公开实施例提供了一种显示面板 10, 如图 2所示, 该显示面板 10包 括显示区 10a和非显示区 10b, 所述显示面板 10进一步包括:
设置在所述非显示区 10b中的至少一个发光芯片 40和控制电路 30, 其 中所述控制电路 30与所述至少一个发光芯片 40连接并且构造用以控制所述 至少一个发光芯片 40发光( light )。
需要说明的是,本公开实施例中不对发光芯片 40的数量进行限制。在一 些实施例中, 控制电路 30是控制多个发光芯片 40同时发光的电路; 在另一 些实施例中,控制电路 30包括控制各个发光芯片 40发光的多个子控制电路。 例如, 考虑到在实际使用中, 希望灵活地控制发光芯片 40发光与否, 显示面 板 10包括多个子控制电路 30, 它们用于分别控制每个发光芯片 40的发光。 在一些实施例中, 所述发光芯片 40和所述控制电路 30设置在显示面板 10 的左右两侧中至少一侧的非显示区 10b中靠近边缘处。
在一些实施例中, 显示面板 10还包括用于将设置在显示面板 10上的发 光芯片 40发出的光导入显示面板 10的部件,例如下文将具体描述的导光板。
相对于通过背光模块中提供的光源进行显示的已知显示面板, 在本公开 的至少一个实施例中, 通过将发光芯片和控制电路设置在显示面板上, 使得 该显示面板可以自带光源而无需再借助外部光源, 从而使所述显示面板借助 自身的光源进行显示, 且当所述显示面板用于显示器时, 可减小背光模块的 整体体积, 有利于显示器的轻薄化。
可选的, 当所述显示面板 10用作液晶显示面板 100时, 如图 3所示, 所 述液晶显示面板 100包括阵列基板 101、彩膜基板 102、 以及设置在所述阵列 基板 101和所述彩膜基板 102之间的液晶层 103。所述发光芯片 40以及控制 所述发光芯片 40发光的控制电路 30均设置在所述阵列基板 101上, 且所述 发光芯片 40设置在所述阵列基板靠近所述彩膜基板 102一侧。所述控制电路 30埋设在阵列基板 101中。
在一些实施例中, 所述液晶显示器还可以包括设置在阵列基板 101远离 彩膜基板 102—侧的导光板 202、 光学膜片 203等, 以使发光芯片 40发出的 光能导入所述液晶显示面板 100的显示区 10a。
这里, 一方面, 如图 4所示, 考虑到在所述液晶显示面板 100的制备过 程中, 由于在阵列基板 101上需要设置驱动所述阵列基板中的晶体管工作的 器件, 因此在切割后形成的液晶显示面板 100中, 阵列基板 101的面积大于 彩膜基板 102的面积, 故而在本公开的至少一个实施例中, 将所述发光芯片 40设置在所述阵列基板 101靠近所述彩膜基板 102的至少一侧,无需使所述 液晶显示面板 100的厚度增加。
另一方面,在图 1所示的液晶显示面板中,光源 201设置在背光模块 200 的左右两侧的至少一侧, 其发出的光需要经过一定长度的空隙才能到达导光 板 202, 这样会导致入射到导光板 202内的光强度不均勾, 当经导光板 202 出射的光射入液晶显示面板 100后, 会导致该液晶显示面板 100出现亮度不 均现象(Hot Spot ); 而在本公开的至少一个实施例中, 当所述液晶显示面板 100应用于液晶显示器时, 为使设置在所述液晶显示面板 100上的发光芯片 40发出的光导入该液晶显示面板 100的显示区 10a, 设置导光板 202且使所 述导光板 202紧靠阵列基板 101,这样,发光芯片 40发出的光到达导光板 202 的间隙比较小, 可以在一定程度上改善入射到导光板 202内的光强度不均匀 的现象, 进而改善液晶显示面板 100出现亮度不均现象。
再一方面, 图 1所示的所述液晶显示器还可包括 PCB (未示出), 所述 PCB包括用于控制光源 201发光的电路, 这样就使得位于背光模块 200左右 两侧中至少一侧处的光源 201需通过引线与 PCB上的电路相连,进而导致光 源 201的功耗会比较大; 而在本公开的至少一个实施例中, 所述控制电路 30 可以通过构图工艺形成在阵列基板 101中, 由于通过构图工艺形成的控制电 路 30中导线的电阻率比较小,使得与控制电路 30连接的发光芯片 40的功耗 比较小。
如前所述,在一些实施例中,所述控制电路 30包括用于控制各个发光芯 片 40发光的多个子控制电路。这样,可以灵活且独立的控制任一个发光芯片 40发光与否。
在一个实施例中, 如图 4、 5所述, 显示面板 10还包括提供有驱动 IC 80 的阵列基板 101。 所述子控制电路包括第一开关单元 301、 第二开关单元 302 以及第三开关单元 303。所述第一开关单元 301的漏极 301c与所述发光芯片 40连接, 所述第一开关单元 301的源极 301b通过所述第二开关单元 302与 驱动 IC 80连接, 所述第一开关单元 301的栅极 301a通过所述第三开关单元 303与驱动 IC 80连接。 驱动 IC 80构造用于分别给所述源极 301b和所述栅 极 301a提供电压。
需要说明的是, 由于所述驱动 IC 80输出数字信号, 需要通过第二开关 单元 302将驱动 IC 80输出的所述数字信号转换为电压信号, 从而给与所述 第二开关单元 302相连接的所述源极 301b提供电压;同样的,所述驱动 IC 80 需要通过第三开关单元 303将驱动 IC 80输出的所述数字信号转换为电压信 号, 从而给与所述第三开关单元 303相连接的所述栅极 301a提供电压。
在一些实施例中, 所述发光芯片 40为 LED ( Light Emitting Diode, 发光 二极管)芯片 400。 由于所述 LED芯片 400只有一个面可以发光, 因此, 当 该 LED芯片 400设置在显示面板 10上时,将发光面设置为使所述 LED芯片 400发出的光射入所述显示面板 10。
例如, 当所述显示面板 10应用于显示器,且该显示器还包括设置于显示 面板 10下方的导光板 202时, 所述 LED芯片的发光面可以靠近显示面板 10 设置, 以使该 LED芯片 400的发光面发出光能到达导光板 202, 并由导光板 202导入显示面板 10的显示区 10a。
在一个实施例中, 如图 6所示, 所述显示面板 100还包括用于封装所述 LED芯片 400的封装胶 50。 这样, 可以使所述 LED芯片 400固定在预定位 置处, 且可以与外界空气隔绝, 更好的保护所述 LED芯片 400, 延长寿命。 例如, 所述封装胶 50是环氧树脂。
在一些实施例中,考虑到诸如所述 LED芯片 400的发光芯片发出的光可 能并非白光, 因此, 显示面板 100还包 ϋ置在所述显示面板 100的非显示 区 10b的荧光粉 60, 所述荧光粉 60用于将入射的 LED芯片 400发出的光转 换为白光。 所述 LED芯片 400设置在所述显示面板的一侧; 沿所述 LED芯 片 400的发光方向, 所述荧光粉 60设置在与所述 LED芯片 400相反的所述 显示面板的另一侧。这样,所述荧光粉 60可以充分接收到所述 LED芯片 400 的发光面发出的光, 进而将其转换为白光。
例如, 如图 7所示, 所述液晶显示面板 100还包括设置在所述阵列基板 101的与所述 LED芯片 400相反侧的荧光粉 60, 所述荧光粉 60用于将入射 的 LED芯片 400发出的光转换为白光。
本公开实施例还提供了一种显示器, 该显示器包括上述的显示面板 10。 例如上述显示器为液晶显示器、 液晶电视、 数码相框、 手机、 平板电脑 等任意需要借助光源来实现显示的产品或部件。
在一个实施例中, 如图 8所示, 所述显示器还包括导光板 202, 所述导 光板 202用于将所述显示面板的发光芯片发出的光导入所述显示面板的显示 区。
通过所述导光板 202,可以将设置在所述显示面板 10的非显示区 10b的 发光芯片 40发出的光导入显示面板 10的显示区 10a, 以使所述显示面板 10 实现显示。
在一些实施例中, 参考图 8所示, 所述显示器还包括设置在所述导光板 202远离所述显示面板 10—侧的反射片 204。 所述显示器还包括设置在导光 板 202与所述显示面板之间的光学膜片 203等, 具体可根据实际情况进行设 定, 在此不再赘述。
下面提供一具体实施例, 以详细描述上述的显示器。 如图 8所示, 所述 显示器包括液晶显示面板 100,所述液晶显示面板 100包括阵列基板 101、彩 膜基板 102、 以及两基板之间的液晶层 103。液晶显示面板 100还包括设置在 所述液晶显示面板 100的显示区 10a中最外侧的偏光片 104; 设置在所述液 晶显示面板 100的非显示区 10b中、且设置在阵列基板 101上的至少一个 LED 芯片 400和控制所述至少一个 LED芯片发光的控制电路 30; 以及设置在靠 近所述阵列基板 101的偏光片 104—侧的光学膜片 203、导光板 202、反射片 204。
在一些实施例中, 液晶显示面板 100还包括用于封装所述 LED芯片 400 的封装胶 50, 以及设置在所述阵列基板 101的与所述 LED芯片 400相反一 侧的荧光粉 60, 用于将发光芯片发出的光转换为白光。
这样,所述 LED芯片 400发出的光通过位于液晶显示面板 100下方的导 光板 202以及反射片 204后, 便可以从导光板 202射出, 经光学膜片 203后 到达所述液晶显示面板 100的显示区 10a, 以给所述液晶显示面板 100提供 光源。
本申请基于并且要求于 2013 年 9 月 22 日递交的中国专利申请第 201310438074.9号的优先权, 在此全文引用上述中国专利申请公开的内容。
以上所述仅是本公开的示范性实施方式, 而非用于限制本公开的保护范 围, 本公开的保护范围由所附的权利要求确定。
