为了能更进一步了解本发明的特征以及技术内容,请参阅以下有关本发明的详细说明与附图,然而附图仅提供参考与说明用,并非用来对本发明加以限制。
附图说明
图1是本发明的显示器的功能方块图。
图2是本发明一实施例的栅极驱动电路的GOA电路单元的电路图。
图3是图2所示各种输入信号、输出信号和节点电压在正向扫描时的时序图。
图4是图2所示各种输入信号、输出信号和节点电压在反向扫描时的时序图。
具体实施方式
请参阅图1,图1是本发明的显示器10的功能方块图。显示器10可以是液晶显示器或是有机发光二极管显示器。显示器10包含玻璃基板14以及源极驱动器(source driver)16。玻璃基板14上设置数个呈矩阵排列的像素(pixel)和栅极驱动(GOA)电路12,而每一个像素包含三个分别代表红绿蓝(RGB)三原色的像素单元20构成。以一个1024×768分辨率的液晶显示器10来说,共需要1024×768×3个像素单元20组合而成。GOA电路12输出扫描信号使得每一行的晶体管22依序开启,同时源极驱动器16则输出对应的数据信号至一整列的像素单元20使其充电到各自所需的电压,以显示不同的灰阶。当同一行充电完毕后,GOA电路12便将该行的扫描信号关闭,然后GOA电路12再输出扫描信号将下一行的晶体管22打开,再由源极驱动器16对下一行的像素单元20进行充放电。如此依序下去,直到所有像素单元20都充电完成,再从第一行开始充电。
在目前的液晶显示面板设计中,GOA电路12即每隔一固定间隔输出扫描信号。以一个1024×768分辨率的液晶显示器10以及60Hz的更新频率为例,每一个画面的显示时间约为1/60=16.67ms。所以每一个扫描信号的脉冲为16.67ms/768=21.7μs。而源极驱动器16则在这21.7μs的时间内,将像素单元20充放电到所需的电压,以显示出相对应的灰阶。
请参阅图2,图2是本发明第一实施例的GOA电路单元SR(n)的电路图。GOA电路12包含数个串接(cascade-connected)的GOA电路单元SR(n)。每一级GOA电路单元SR(n)用来依据前一级GOA电路单元SR(n-1)输出的扫描信号G(n-1)、后一级GOA电路单元SR(n+1)输出的扫描信号G(n+1)、第一时钟信号CKV1、第二时钟信号CKV2、第三时钟信号CKV3,在输出端OUT输出扫描信号G(n)。每一级GOA电路单元SR(n)包含输入控制模块100、输出控制模块200和下拉模块300。输入控制模块100用来依据第一时钟信号CKV1和第三时钟信号CKV3,在控制节点Q输出控制信号Q(n)。输出控制模块200电性连接于控制节点Q,用来依据控制信号Q(n)和第二时钟信号CKV2,在输出端OUT输出扫描信号G(n)。下拉模块300电性连接输出控制模块200,用来将扫描信号G(n)下拉至低电平。
下拉模块300包含第一晶体管T1、第二晶体管T2、第三晶体管T3和电阻R1。第一晶体管T1的栅极电性连接控制节点Q,其漏极电性连接下拉驱动节点P,其源极电性连接第一固定电压VGL。第二晶体管T2的栅极电性连接下拉驱动节点P,其漏极电性连接输出端OUT,其源极电性连接第一固定电压VGL。第三晶体管T3的栅极电性连接下拉驱动节点P,其源极电性连接第一固定电压VGL。电阻R1的两端分别电性连接第二固定电压VGH和下拉驱动节点P。
输入控制模块100包含第四晶体管T4和第五晶体管T5。第四晶体管T4的栅极电性连接第一时钟信号CKV1,其漏极电性连接前一级GOA电路单元SR(n-1)输出的扫描信号G(n-1),其源极电性连接控制节点Q。第五晶体管T5的栅极电性连接第三时钟信号CKV3,其漏极电性连接控制节点Q,其源极电性连接后一级GOA电路单元SR(n+1)输出的扫描信号G(n+1)。
输出控制模块200包含第六晶体管T6、第七晶体管T7和电容C1。第六晶体管T6的栅极电性连接第二固定电压VGH,其漏极电性连接控制节点Q,其源极电性连接第三晶体管T3的漏极。第七晶体管T7的栅极电性连接第六晶体管T6的源极,其漏极电性连接第二时钟信号CKV2,其源极电性连接输出端OUT。电容C1的两端分别连接第七晶体管T7的源极和栅极。
依据图2所示的实施例,每一晶体管皆为N型金氧半导体(N-type metal oxidesemiconductor,NMOS)晶体管。第一时钟信号CKV1、第二时钟信号CKV2和第三时钟信号CKV3的脉冲是依序轮流输出,且互不重叠。第一固定电压VGL为低电平,第二固定电压VGH为高电平。
请一并参阅图2和图3,图3是图2所示各种输入信号、输出信号和节点电压在正向扫描时的时序图。在图3所示的t1期间,第一时钟信号CKV1和扫描信号G(n-1)皆为高电平,此时晶体管T4开启,使得高电平的扫描信号G(n-1)会经由晶体管T4传送至控制节点Q,此时控制信号Q(n)也是处于高电平。因为第二固定电压VGH一直处于高电平,所以晶体管T6会一直保持开启,此时晶体管T6导通高电平的控制信号Q(n)以对电容C1充电。同时,晶体管T1也会因为高电平的控制信号Q(n)而开启,使得低电平的第一固定电压VGL通过晶体管T1传送至下拉驱动节点P,所以下拉驱动信号P(n)处于低电平。在t2期间,因为电容C1保持电荷的因素,因此晶体管T7会开启以导通高电平的第二时钟信号CKV2至输出端OUT,使得扫描信号G(n)变为高电平。在t3期间,第三时钟信号CKV3和扫描信号G(n+1)皆为高电平,此时晶体管T5开启,使得高电平的扫描信号G(n+1)会经由晶体管T5传送至控制节点Q。高电平的控制信号Q(n)通过晶体管T6传送至晶体管T7的栅极,使得晶体管T7导通低电平的第二时钟信号CKV2至输出端OUT。此时扫描信号G(n)变为低电平。在t4期间,第一时钟信号CKV1为高电平而扫描信号G(n-1)为低电平,此时晶体管T4开启。低电平的扫描信号G(n-1)会经由晶体管T4传送至控制节点Q,导致控制信号Q(n)变为低电平。在t5期间,因为控制信号Q(n)处于低电平,因此晶体管T1断开,下拉驱动信号P(n)会因为第二固定电压VGH的影响而变为高电平。此时晶体管T2和T3导通低电平的第一固定电压VGL,因此晶体管T7的电位和扫描信号G(n)此时皆为低电平。所以可以保证控制信号Q(n)及扫描信号G(n)为稳定的低电平。
图4是图2所示各种输入信号、输出信号和节点电压在反向扫描时的时序图。图4与图3的差异在于正向扫描和反向扫描的时序稍有不同,但是本领域技术人员可依据图2所揭示的GOA电路单元SR(n)的架构了解两者的时序差异,在此不另赘述。
本实施例的每一晶体管是以NMOS晶体管为例做说明,但是本领域技术人员可以根据本发明的电路将其中全部或是部分NMOS晶体管以PMOS晶体管取代,以实现同样功能的GOA电路单元,以下不再赘述。
本发明的栅极驱动电路12的每一级GOA电路单元SR(n)的下拉模块300使用数量较少的晶体管和电容,因此具有便于窄边框显示器设计的有益效果。另外,GOA电路单元SR(n)的下拉模块300省略电容,因此可以减少因对该电容充电而产生的功耗,具有减少整体GOA电路功耗的有益效果。
综上所述,虽然本发明已以较佳实施例揭露如上,但该较佳实施例并非用以限制本发明,该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。
