附图说明
为让本发明的上述内容能更明显易懂,下文特举优选实施例,并配合所附图式,作详细说明如下:
图1为本发明的显示面板的优选实施例的结构示意图。
本发明的最佳实施方式
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」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,结构相似的单元是以相同标号表示。
请参照图1,图1为本发明的显示面板的优选实施例的结构示意图。本优选实施例的显示面板10包括数据线(图中未示出)、扫描线(图中未示出)、以及由数据线和扫描线交错形成的多个像素单元11,其中每个像素单元11包括多个子像素单元111,如红色子像素单元、蓝色子像素单元以及绿色子像素单元,同一像素单元11的子像素单元111沿数据线的延伸方向设置。同一像素单元11的子像素单元111与相同的数据线连接,同时与不同的扫描线连接。
该显示面板10还包括用于给数据线提供数据信号的数据驱动模块12以及用于给扫描线提供扫描信号的扫描驱动模块13。扫描驱动模块13包括多个用于生成扫描信号的扫描信号生成芯片131。
数据驱动模块12包括脉宽调制芯片121、伽马校正芯片122、时序控制芯片123以及数据信号生成芯片124。脉宽调制芯片121用于控制数据信号的脉冲宽度;伽马校正芯片122用于控制数据信号的信号强度,以调整显示画面的画面参数;时序控制芯片123用于控制数据信号的产生时序;数据信号生成芯片124用于生成数据信号。
其中脉宽调制芯片121以及伽马校正芯片122设置在印刷电路板上,时序控制芯片123和数据信号生成芯片124设置在柔性电路板上(如通过覆晶薄膜COF(Chip On Film)的形式等),印刷电路板通过柔性电路板与数据线连接。由于时序控制芯片123和数据信号生成芯片124设置在柔性电路板上,时序控制芯片123可采用P2P协议与数据信号生成芯片124通信,也可采用mini-LVDS协议与数据信号生成芯片124通信。
请参照图1,该显示面板10的解析度为1920*1080,因此该显示面板10包括1920条数据线以及3240(1080*3)条扫描线。这样扫描驱动模块13包括6个具有540通道的扫描信号生成芯片131,以给3240条扫描线提供扫描信号;数据驱动模块12包括2个具有960通道的数据信号生成芯片124,以给1920条数据线提供数据信号。
本优选实施例的显示面板10使用时,数据驱动模块12中的数据信号生成芯片124在脉宽调制芯片121、伽马校正芯片122以及时序控制芯片123的作用下生成相应的数据信号;扫描驱动模块13中的扫描信号生成芯片131生成相应的扫描信号。
显示面板10中的每行子像素单元111连接同一扫描线,由于同一像素单元11的子像素单元111沿数据线的延伸方形设置,因此同一像素单元11的子像素单元111均连接不同的扫描线。这样本优选实施例的显示面板10显示画面时,通过扫描线上的扫描信号逐行开启每行的子像素单元111,再通过数据线向子像素单元111输入数据信号,以达到相应的显示效果。
在本优选实施例中由于纵向设置同一像素单元11的子像素单元111,因此整个显示面板10需要1920条数据线以及3240条扫描线,通过增加扫描线的数量大大减少了数据线的数量,从而可以较好的缩小显示面板10的数据驱动模块12一侧的边框体积。同时数据驱动模块12只需要设置2个960通道的数据信号生成芯片124,因此还可降低数据驱动模块12的制作成本。
此外由于数据信号生成芯片124的减少,本优选实施例还可将数据信号生成芯片124通过覆晶薄膜的方式设置在柔性电路板上,从而可进一步减少数据驱动模块12中印刷电路板的面积,通过柔性电路板的设置即实现了走线,又实现了数据信号生成芯片124和时序控制芯片123的设置,使得数据驱动模块12的整体结构简单,且制作成本较低
为了便于柔性电路板上的数据信号生成芯片124和时序控制芯片123的稳定工作,这里时序控制芯片123优选采用P2P协议与数据信号生成芯片124通信,或采用mini-LVDS协议与数据信号生成芯片124通信。
本发明的显示面通过增加扫描线的数量,有效的减少了数据线的数量;同时将数据驱动模块中的时序控制芯片和数据信号生成芯片设置在柔性电路板上,有效的减小了数据驱动模块的体积;从而有效的缩小了显示面板的边框体积,并且这个数据驱动模块的结构简单、制作成本较低。
本发明还提供一种显示装置,该显示装置包括显示面板,显示面板包括数据线、扫描线以及由数据线和扫描线交错形成的多个像素单元,其中每个像素单元包括多个子像素单元,同一像素单元的子像素单元与相同的数据线连接,同时与不同的扫描线连接。
该显示面板还包括用于给数据线提供数据信号的数据驱动模块以及用于给扫描线提供扫描信号的扫描驱动模块。扫描驱动模块包括多个用于生成扫描信号的扫描信号生成芯片。

脉宽调制芯片以及伽马校正芯片设置在印刷电路板上,时序控制芯片和数据信号生成芯片设置在柔性电路板上,印刷电路板通过柔性电路板与数据线连接。
优选的,同一像素单元的子像素单元沿数据线的延伸方向设置。

本优选实施例的显示装置的具体工作原理与上述的显示面板的优选实施例中的描述相同或相似,具体请参见上述显示面板的优选实施例中的相关描述。
本发明的显示面板及显示装置通过增加扫描线的数量,有效的减少了数据线的数量,由于数据线减少的数量大于扫描线增加的数量,因此可有效的减少数据驱动模块中的控制芯片数量;同时将数据驱动模块中的时序控制芯片和数据信号生成芯片设置在柔性电路板上,有效的减小了数据驱动模块的体积;从而有效的缩小了显示面板的边框体积,并且这个数据驱动模块的结构简单、制作成本较低;有效的解决了现有的显示面板及显示装置的体积较大、驱动电路结构较为复杂以及制作成本较高的技术问题。
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。
