本发明目的的实现、功能特点及优点将结合实施例,参照附图做进一步说明。
具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明的一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
需要说明,本发明实施例中所有方向性指示(诸如上、下、左、右、前、后……)仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等,如果该特定姿态发生改变时,则该方向性指示也相应地随之改变。

本发明提出一种显示驱动方法。
参照图1,在本发明实施例中,该显示驱动方法,可应用于超高清显示面板,所述超高清显示面板例如可采用FHD(Full High Definition,全高清)逻辑板驱动,包括以下步骤:
S100、接收输入的图像信号,解码后分为左分区图像信号及右分区图像信号;
S200、将左分区图像信号复制得到第一左分区图像信号及第二左分区图像信号,将右分区图像信号复制得到第一右分区图像信号及第二右分区图像信号;
S300、将所述第一左分区图像信号、第二左分区图像信号,及第一右分区图像信号、第二右分区图像信号输入至显示面板,并根据栅极驱动信号,对图像进行显示。
需要说明的是,FHD图像信号的清晰度要低于UD的图像信号清晰度。由于采用的显示面板是次品,例如可能显示面板中有一些像素点有缺陷。对于UD图像信号,这些有缺陷的显示面板不能完整显示图像,但是对于低清晰度的FHD图像信号则则可以降低人眼对缺陷的敏感程度。
本实施例中,将输入的FHD图像信号最终分成四路信号,分别为第一左分区图像信号、第二分区图像信号,及第一右分区图像信号、第二右分区图像信号,每一分区图像信号各负责1/4的画面显示,以去匹配UD的显示面板。
参照图2,图2为本发明技术方案的基于UD显示面板架构来显示FHD图像信号的示意图。
例如,输入的图像低清晰度的FHD图像信号解析度分别为11、12、13、21、22、23、31、32、33,经过FHD的TCON解码及复制处理后,单个解析度都被复制成了四个,在UD的显示面板上呈现的显示效果就是相邻的上下左右的像素点均显示相同的解析度。实现了FHD图像信号在UD显示面板上显示。
参照图3,通常IPS、VA、TN、OCB等类型的显示面板的驱动是由源极驱动器和栅极驱动器共同配合驱动完成的。FHD图像信号输入至TCON后,经变换处理后生成了显示的数据信号,及源极驱动器和栅极驱动器的时钟控制信号。具体是,通过源极驱动器装载数据信号,通过栅极驱动器控制时序,实现了图像的扫描显示。
本发明技术方案通过将输入的FHD进行解码得到左分区图像信号和右分区图像信号,再进一步的将左分区图像信号复制后分为两路完全一样的信号,将右分区的图像信号进行复制后分为两路完全一样的信号,如此得到UD显示面板所需的四路图像信号:第一左分区图像信号、第二左分区图像信号、第一右分区图像信号、及第二右分区图像信号,再结合显示面板的栅极驱动信号,将FHD的图像信号显示与UD显示面板上,采用FHD的驱动方式来将FHD图像信号显示于UD显示面板上,相较于现有的UD驱动方式,其硬件成本大大降低了,从而降低了UD玻璃面板的次品整体成本。
参照图4及图5,本发明实施例中,采用UD的1D1G(其中,D表示数据线,G表示扫描线,数据线和扫描线独立输入的数量均为1)驱动架构方案。该驱动架构包括12颗源极驱动器以及12颗栅极驱动器。其中,12颗源极驱动器以及12颗栅极驱动器呈对称设置。
实际设置中,12颗源极驱动器分成左右两组,每一组均包括6颗源极驱动器。其中,每3颗源极驱动器共用一个数据接口。因而12颗源极驱动器总共包括四个数据接口,以分别接收FHD TCON输入的四路图像信号。
由于左右两组源极驱动结构完全相同,这里以右边的一组进行说明。
右边的一组包括由向左依次排列的源极驱动器S1、S2、S3、S4、S5、S6。每一源极驱动器包括1路时钟线、6路数据线及1路数据传输触发线。源极驱动器S1、S2、S3共用一个数据接口,S4、S5、S6则共用一个数据接口。
其中S1、S2、S3的各自6路数据线一一短接、时钟线一一短接、数据传输触发线一一短接,短接之后的从A接口引出,与TCON板连接。同理,S4、S5、S6短接之后从B接口引出。A接口的引出线包括1路时钟线R-ACLK,6路数据线分别为R-ALV0~R-ALV5;B接口的引出线包括1路时钟线R-BCLK,6路数据线分别为R-BLV0~R-BLV5。A、B接口还各包括数据传输触发线S3-DIO1、S4-DIO2。此外,右边的一组还包括有模式切换线UCFT mode,该切换线分别与S1、S2、S3、S4、S5、S6连接,以便于切换UD模式和FHD模式两种显示驱动模式。
易于理解的是,左边的一组包括C接口及D接口;C接口的引出线包括1路时钟线R-CCLK,6路数据线分别为R-CLV0~R-CLV5;D接口的引出线包括1路时钟线R-DCLK,6路数据线分别为R-DLV0~R-DLV5。C、D接口还各包括数据传输触发线S9-DIO3、S10-DIO4。此外,左边的一组还包括有模式切换线UCFT mode,该切换线分别与S7、S8、S9、S10、S11、S12连接,以便于切换UD模式和FHD模式两种显示驱动模式。
每一个源极驱动器驱动320列像素,12个源极驱动器总共驱动3840列像素。
本实施例中,还包括12颗栅极驱动器分别为GR1~GR6,GL1~GL6,其中GR1~GR6位于显示面板的右侧,GL1~GL6位于显示面板的左侧。每一栅极驱动器驱动360行像素。本实施例中,共有2160行像素,P1~P2160。具体地,所述栅极驱动信号对显示面板的扫描线成对驱动。即先驱动P1/P2,然后依次P3/P4、P5/P6······一直到P2159/P2160。
参照图6,图6为栅极驱动的波形图,由图可以看出,栅极驱动信号G1~G2160成对驱动。成对的驱动信号依次对P1~P2160进行驱动。其中OE为使能信号,DATE为数据时钟信号。
本实施例中,所述第一左分区图像信号及所述第二左分区图像信号均为差分信号。即接口A、B、C、D输入为mini LVDS。
具体地,所述步骤“将左分区图像信号复制得到第一左分区图像信号及第二左分区图像信号,将右分区图像信号复制得到第一右分区图像信号及第二右分区图像信号”包括:
将第一左分区图像的信号线与第二左分区图像信号的信号线一一连接后接收输入的所述左分区图像信号;将第一右分区图像的信号线与第二右分区图像信号的信号线一一连接后接收输入的右分区图像信号。本实施例中是通过短接每个源极驱动器对应的输入线来复制信号。
具体地,所述第一左分区图像信号、第二左分区图像信号、第一右分区图像信号、第二右分区图像信号均包括两路RGB像素信号。
需要说明的是,例如R-ALV0~R-ALV2输入1路RGB像素信号,R-ALV3~R-ALV5输入1路RGB像素信号。
参照图7,本发明还提出一种基于显示驱动装置,该显示驱动装置可应用于显示器上,平板显示器、电视机显示屏、电脑显示屏等,其中平板显示器例如为液晶显示器、等离子体显示器、电致发光显示器等。该显示驱动装置包括:
解码模块100:接收输入的图像信号,解码后分为左分区图像信号及右分区图像信号;
时序处理模块200:将左分区图像信号复制得到第一左分区图像信号及第二左分区图像信号,将右分区图像信号复制得到第一右分区图像信号及第二右分区图像信号;
驱动模块300:将所述第一左分区图像信号、第二左分区图像信号,及第一右分区图像信号、第二右分区图像信号输入至显示面板,结合栅极驱动信号,对图像进行显示。
具体地,所述栅极驱动信号对显示面板的扫描线成对驱动。
优选地,所述第一左分区图像信号及所述第二左分区图像信号均为差分信号。
具体地,其特征在于,所述时序处理模块:
将第一左分区图像的信号线与第二左分区图像信号的信号线一一连接后接收输入的所述左分区图像信号;将第一右分区图像的信号线与第二右分区图像信号的信号线一一连接后接收输入的右分区图像信号。
具体地,所述第一左分区图像信号、第二左分区图像信号、第一右分区图像信号、第二右分区图像信号均包括两路RGB像素信号。
本发明技术方案有效降低了基于UD架构显示面板的驱动成本。
本发明还提出一种显示装置,该显示装置包括上述显示驱动装置,该显示驱动装置的具体结构参照上述实施例,由于本显示装置采用了上述所有实施例的全部技术方案,因此至少具有上述实施例的技术方案所带来的所有有益效果,在此不再一一赘述
