本发明的实施方式
下面将结合本申请实施例中的附图,对本申请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申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域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,都属于本申请保护的范围。
本申请提供一种显示装置,该显示装置可以是智能手机、平板电脑、电子书阅读器、智能手表、摄像机、游戏机等,本申请对此不作限定。
请参阅图1,图1是本申请提供的显示装置的第一结构示意图。如图1所示,本申请实施例提供的显示装置1000包括数据驱动芯片100、时序控制器200以及显示面板300。
其中,时序控制器200用于向数据驱动芯片100提供时序控制信号。数据驱动芯片100用于向显示面板300提供显示数据,以驱动显示面板300进行画面显示。
其中,数据驱动芯片100可直接贴附在显示面板300的基板上,也可通过覆晶薄膜绑定在显示面板300上,本申请对此不做具体限定。
其中,数据驱动芯片100的数量可以是一个或者多个,具体可根据显示面板300的像素分辨率进行设定,本申请对此不作具体限定。
进一步的,本申请实施例提供的数据驱动芯片100包括锁存模块10和输出模块20。锁存模块10用于接收当前显示数据D(n),并对当前显示数据D(n)进行锁存,待当前显示数据D(n)锁存后,输出当前显示数据D(n)。输出模块20用于将锁存模块10输出的当前显示数据D(n)输出至显示面板300。其中,锁存模块10还用于当输出模块20输出当前显示数据D(n)时,清除锁存在锁存模块10内的当前显示数据D(n)。
由此可知,在本申请实施例提供的数据驱动芯片100中,通过将锁存模块10配置为在输出模块20输出当前显示数据D(n)至显示面板300时,清除锁存在锁存模块10内的当前显示数据D(n),则锁存模块10可以在清除当前显示数据D(n)后,继续锁存下一显示数据。即,在本申请提供的数据驱动芯片100内,只需要设置一组锁存模块10即可实现多行显示数据的锁存以及传输,使得锁存模块10的数量大大减少,从而可以有效减小数据驱动芯片100的尺寸。同时由于简化了当前显示数据D(n)在数据驱动芯片100中的传输路径,减少了二次传输所需的时间,从而提高了当前显示数据D(n)的传输速率。
在本申请实施例提供的数据驱动芯片100中,锁存模块10以及输出模块20的数量可根据数据驱动芯片100的规格或者显示面板300的像素分辨率进行设置,本申请对此不作具体限定。
在本申请实施例中,输出模块20可以包括电平转换器、数模转换器以及模拟缓冲放大器。电平转换器用于将电源电压转换为合适的工作电压以提供给数模转换器。数模转换器用于基于灰阶电压将当前显示数据D(n)转换为模拟信号。模拟缓冲放大器用于放大模拟化的当前显示数据D(n),并将其输出至显示面板300。
请参阅图2,图2是本申请提供的数据驱动芯片中的第一信号时序图。结合图1和图2可知,在本申请实施例中,数据驱动芯片100接收一时钟信号TP。锁存模块10用于在时钟信号TP的当前上升沿Tr来临之前对当前显示数据D(n)进行锁存,并且待当前显示数据D(n)锁存后,输出当前显示数据D(n)。输出模块20用于在时钟信号TP的当前上升沿Tr来临之前接收锁存模块10输出的当前显示数据D(n),并在时钟信号TP的当前上升沿Tr来临之际,输出当前显示数据D(n)至显示面板300。其中,时钟信号TP可由时序控制器200提供。
具体的,请参阅图3,图3是本申请提供的锁存模块的锁存方式示意图。如图3所示,在本申请实施例中,当前显示数据D(n)包括多个数据信号。锁存模块10具体用于接收一锁存控制时钟信号CLK,并在锁存控制时钟信号CLK的每一上升沿处和每一下降沿处均接收一个数据信号,且锁存模块10在每接收一个数据信号后,均对该数据信号进行锁存。即在本申请实施例中,锁存模块10配置为采用传输边锁存的方式对当前显示数据D(n)进行锁存。该锁存方式可以有效提高锁存模块10的锁存速度,进而提高数据驱动芯片100的工作效率。
需要说明的是,在本申请实施例中,锁存模块10还用于在清除锁存模块10内的当前显示数据D(n)后,在锁存控制时钟信号CLK的上升沿来临之际对下一显示数据D(n+1)进行锁存,以保证锁存模块10在当前显示数据D(n)被完全清除后,才开始锁存下一显示数据D(n+1),避免数据锁存错误。
此外,时钟信号TP仅用于在当前上升沿Tr处触发输出模块20,以使得输出模块20将当前显示数据D(n)输出至显示面板300,因此,本申请实施例无需对时钟信号TP的脉冲宽度进行限定。此外,输出脉冲宽度较窄的时钟信号TP,可以减小时序控制器200的功耗。
进一步的,在本申请实施例中,锁存模块10接入一输出控制信号Ft。输出控制信号Ft用于在输出时间段t2内作用于锁存模块10,使得锁存模块10在将当前显示数据D(n)锁存完毕后,可以响应于该输出控制信号Ft以输出当前显示数据D(n)至输出模块20。
其中,在时钟信号TP的当前上升沿Tr来临之前,锁存模块10能够在输出时间段t2内将当前显示数据D(n)完全传输至输出模块20即可。因此,本申请实施例对输出时间段t2的时长不作具体限定。
在本申请实施例中,锁存模块10接入一重置控制信号Re。重置控制信号Re用于在重置时间段t1内作用于锁存模块10,以使得锁存模块10清除锁存在其内的当前显示数据D(n)。
其中,在重置时间段t1内,锁存模块10能够完全清除锁存在其内的当前显示数据D(n)即可。因此,本申请实施例对重置时间段t1的时长不作具体限定。
需要说明的是,理想情况下,输出模块20可在时钟信号TP的当前上升沿Tr来临之际将当前显示数据D(n)完全输出至显示面板300,输出时间可忽略不计。但是考虑到信号走线的阻抗以及其他影响因素,输出模块20输出当前显示数据D(n)的时间可能存在一定的延时。因此,本申请实施例通过设置重置时间段t1(即设置重置控制信号Re),能够在锁存模块10完全清除锁存在其内的当前显示数据D(n)的同时,提供输出模块20将当前显示数据D(n)输出至显示面板300所需的延迟时间。
进一步的,在本申请实施例中,输出时间段t2对应时钟信号TP的当前上升沿Tr设置,重置时间段t1对应时钟信号TP的当前下降沿Tf设置。
可以理解的是,锁存模块10需要在时钟信号TP的当前上升沿Tr到来之前将当前显示数据D(n)全部锁存,并传输至输出模块20,因此,输出时间段t2的结束节点需要位于时钟信号TP的当前上升沿Tr到来之前或者位于时钟信号TP的当前上升沿Tr处。同理,由于本申请实施例无需对时钟信号TP的脉冲宽度进行限定,因此,重置时间段t1的结束节点位于时钟信号TP的当前下降沿Tf到来之前、到来之际或者到来之后均可。
此外,在本申请实施例中,无需对时钟信号TP的当前上升沿Tr和相应的重置控制信号Re的起始节点之间的时序关系进行限定,进而可以简化数据驱动芯片100中的信号时序,降低设计难度。
具体的,在本申请一些实施例中,锁存模块10可在时钟信号TP的当前上升沿Tr到来之后,接入重置控制信号Re,如图2所示;当然,在本申请另一些实施例中,锁存模块10可在时钟信号TP的当前上升沿Tr来临之际,接入重置控制信号Re,如图4所示。
需要说明的是,在本申请实施例中,重置控制信号Re以及输出控制信号Ft均由时序控制器200提供。当前显示数据D(n)可由系统芯片(图中未标示)或者时序控制器200提供。其中,系统芯片和时序控制器200的结构以及工作原理均为本领域技术人员熟知的技术,在此不再赘述。
基于本申请实施例,数据驱动芯片100的数据传输方法包括以下步骤:锁存模块10在时钟信号TP的当前上升沿Tr来临之前对当前显示数据D(n)进行锁存;待当前显示数据D(n)锁存后,锁存模块10在输出时间段t2内输出当前显示数据D(n);输出模块20在时钟信号TP的当前上升沿Tr来临之际,输出当前显示数据D(n)至显示面板300;当输出模块20输出当前显示数据D(n)时,锁存模块10基于重置控制信号Re,在重置时间段t1内清除锁存在其内的当前显示数据D(n)。数据驱动芯片100正是通过上述数据传输方法实现了对多行显示数据的传输。
其中,锁存模块10在锁存当前显示数据D(n)之前,已完成了清除锁存在其内的上一显示数据D(n-1)的步骤;锁存模块10还会在完成清除锁存在其内的当前显示数据D(n)的步骤后,在时钟信号TP的下一上升沿来临之前对下一显示数据D(n+1)进行锁存。其中,n为大于1的正整数。
请参阅图5,图5是本申请提供的显示装置的第二结构示意图。其中,图5所示的显示装置1000与图1所示的显示装置1000的不同之处在于,在图5所示的显示装置1000中的数据驱动芯片100中,输出模块20还用于当其输出当前显示数据D(n)至显示面板300后,输出一反馈信号FB至锁存模块10,以使得锁存模块10清除锁存在锁存模块10内的当前显示数据D(n)。
具体的,锁存模块10在时钟信号TP的当前上升沿Tr来临之前对当前显示数据D(n)进行锁存;待当前显示数据D(n)锁存后,锁存模块10在输出时间段t2内输出当前显示数据D(n);输出模块20在时钟信号TP的当前上升沿Tr来临之际,输出当前显示数据D(n)至显示面板300;其中,输出模块20还用于在输出当前显示数据D(n)至显示面板300时,立即输出一反馈信号FB至锁存模块10,以使得锁存模块10在输出模块20输出当前显示数据D(n)时,响应于该反馈信号FB,在重置时间段t1内清除锁存在其内的当前显示数据D(n)。
由此,时序控制器200无需向锁存模块10提供重置控制信号Re,可以减少时序控制器200的功耗,并简化数据驱动芯片100与时序控制器200之间的信号传输。同时,输出模块20在输出当前显示数据D(n)至显示面板后,立即输出反馈信号FB至锁存模块10,可以减少锁存模块10清除锁存在其内的当前显示数据D(n)的响应时间,进而提高数据驱动芯片100的工作效率。
本申请提供的显示装置1000包括数据驱动芯片100,数据驱动芯片100通过将锁存模块10配置为当输出模块10输出当前显示数据D(n)时,清除锁存在锁存模块10内的当前显示数据D(n),以便于锁存模块10对下一显示数据进行锁存,从而使得数据驱动芯片100内不需要设置两组锁存模块10就能输出当前显示数据D(n)。因此,相较于现有技术,本申请提供的数据驱动芯片100中的锁存模块10的数量大大减少,从而可以有效减小数据驱动芯片100的尺寸;同时由于简化了当前显示数据D(n)在数据驱动芯片100中的传输路径,提高了当前显示数据D(n)的传输速率,从而提高了显示装置1000的品质。
以上对本申请提供的数据驱动芯片以及显示装置进行了详细介绍,本文中应用了具体个例对本申请的原理及实施方式进行了阐述,以上实施例的说明只是用于帮助理解本申请的方法及其核心思想;同时,对于本领域的一般技术人员,依据本申请的思想,在具体实施方式及应用范围上均会有改变之处,综上所述,本说明书内容不应理解为对本申请的限制。
