详细描述
下面将结合本公开实施例中的附图,对本公开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公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做 出创造性劳动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。
在本公开的实施例中,“多个”的含义是两个或两个以上,除非另有明确具体的限定。
相关技术中的提升输入信号质量的方法是:显示面板的控制芯片TCON芯片在接收到前端系统传送的输入信号后,对信号的摆幅(即信号Swing)进行调整,这样可以使信号的波动明显,从而更易获得有效的信号输出。参考图1所示,原输入信号的眼图中,眼高约为182mV。将图1所示的输入信号的摆幅增大后,其信号的眼图如图2所示,眼高约为426mV,增幅约为240mV,信号质量得到了提升,显示面板更易从图2所示的信号中获得有效信号。
但是信号的摆幅提升后,由于信号得到了增强,显示面板的电磁兼容性(Electromagnetic Compatibility,EMC)也会随之增大,这样不仅会对周边电子产品产生电磁干扰,而且更易受其它电子产品的干扰。
本公开的实施例提供一种时序控制器、显示装置、信号调整方法,该时序控制器可以在提升输入信号质量的同时,降低因增强信号带来的EMC干扰。
本公开实施例提供了一种时序控制器,参考图3所示,该时序控制器包括:接收电路1、时序控制电路2、多个插损电路3;接收电路1、插损电路3分别与时序控制电路2相连。
接收电路被配置为接收N帧信号。
一实施例中,时序控制电路被配置为:
在第M帧信号的消隐阶段,检测第M-1帧信号的误码率;
根据所述第M-1帧信号的误码率对应的目标摆幅值,调整所述第M-1帧信号的摆幅;
根据第M-1帧信号的误码率对应的目标摆幅值,选择对应的插损电路,以损耗调整第M-1帧信号的摆幅所产生的能量;其中,M、N均为正整数,且1<M≤N。
可选地,根据所述第M-1帧信号的误码率对应的目标摆幅值,调整所述第M-1帧信号的摆幅,这一操作可以包括:
确定第M-1帧信号的误码率,在预存的摆幅调节表中所属的误码率区间;以及
根据摆幅调节表中误码率区间与目标摆幅值的对应关系,调整第M-1帧信号的摆幅。
上述接收电路可以包括接口,该接口类型不做限定,可以根据前端系统输出的信号类型确定。
时序控制电路可以为利用印刷或其他的方式印制在电路板上的电路,或是时序控制芯片等,上述时序控制芯片的类型也不做限定,其可以是单片机、ARM(Advanced RISC Machines,高级精简指令集运算机器)或者FPGA(Field Programmable Gate Array,现场可编程门阵列)等芯片,具体可以根据实际设计要求确定。
上述插损电路的具体结构和数量均不做限定,只要可以满足损耗信号能量的作用即可。图3中以时序控制器包括3个插损电路为例进行绘示。
需要说明的是,参考图4所示,以帧频为分时点,一帧信号包括有效区10和消隐区11;其中,有效区(active zone)对应信号的有效时间,消隐区(blanking zone)对应信号的准备时间。将上述时序控制器应用到显示装置中,有效区对应显示画面阶段,消隐区对应不显示画面阶段(消隐区对应时间非常短暂,人眼难以感受)。上述第M帧信号的消隐阶段即对应第M帧信号的消隐区。参考图5所示,本公开中,在消隐区11增加了误码率(Bit Error Rate,BER)检测区112,即在第M帧信号的消隐阶段进行第M-1帧信号的误码率的侦测。
上述摆幅调节表可以预存在时序控制电路,表中的误码率区间与目标摆幅值的具体内容可以根据实际情况而定。
本公开的实施例提供了一种时序控制器,该时序控制器(Timing Controller,TCON)在调整信号摆幅的同时,采用插损电路损耗调整信号摆幅所产生的能量,从而可以在提升输入信号质量的同时,降低因增强信号带来的EMC干扰。
可选的,所有插损电路分为多组插损单元,每组插损单元包括第一插损电路和第二插损电路,第一插损电路用于损耗第一频率的信号,第二插损电路用于损耗第二频率的信号,第一频率小于第二频率。
信号有高频信号和低频信号之分,采用第一插损电路可以损耗低频信号能量,采用第二插损电路损耗高频信号能量,这样可以最大程度地损耗信号,进一步降低EMC能量干扰。
可选的,摆幅调节表中的目标摆幅值与插损单元一一对应,即摆幅调节 表中的目标摆幅值、同一插损单元中的第一插损电路、第二插损电路三者是一一相互对应关系,可以降低设计难度。在其他可选的实施例中,摆幅调节表中的目标摆幅值与插损单元也可以不是一一对应的关系。
可选的,每组插损单元中,参考图6所示,第一插损电路包括:电容C1、第一开关S5、第一接地端GND和第二接地端Ground;电容C1的两端分别连接第一接地端GND和第一开关S5的第一端(图6未标记),第一开关S5的第二端(图6未标记)连接第二接地端Ground。
参考图7所示,第二插损电路包括:磁珠B1、第二开关S1、第三接地端GND和第四接地端Ground;磁珠B1的两端分别连接第三接地端GND和第二开关S1的第一端(图7未标记),第二开关7的第二端(图7未标记)连接第四接地端Ground。
需要说明的是,图6和图7分别以四个第一插损电路和四个第二插损电路为例进行绘示,此时对应的摆幅调节表可以如表一所示。
表一
误码率区间 目标摆幅值
≤BER1 Swing1
BER1-BER2 Swing2
BER2-BER3 Swing3
≥BER3 Swing4
为了便于描述,图6中四个第一插损电路中的电容分别标记为C1、C2、C3、C4,与C1、C2、C3、C4分别对应的第一开关分别标记为S5、S6、S7、S8;图7中四个第二插损电路中的磁珠分别标记为B1、B2、B3、B4,与B1、B2、B3、B4分别对应的第二开关分别标记为S1、S2、S3、S4。这里开关S1-S8由时序控制电路控制,当目标摆幅值位于档位1(Swing1)时,S1及S5闭合,组成档位1插损单元;当目标摆幅值位于档位2(Swing2)时,S2及S6闭合,组成档位2插损单元,依此类推。每个档位的插损单元中的磁珠(Bead)及电容的值通过提前模拟调试确定。
结合图6和图7所示,所有第一插损电路的第一接地端和所有第二插损电路的第三接地端为同一接地端(GND),所有第一插损电路的第二接地端和所有第二插损电路的第四接地端为同一接地端(Ground)。
上述图6和图7的版图(Layout)可以参考图8所示,接地端GND Pad区域标记为21,GND为时序控制器中驱动电路的逻辑地;接地端Ground Pad区域标记为20,采用面状(Plane Shape)布置,将上述时序控制器应用到液 晶显示器中,Ground可以是液晶显示器的背板中的接地区;B1-B4、C1-C4一端引脚(Pin)用面状(Plane Shape)方式与Ground Pad20连接,一端引脚通过模拟控制开关(图8未示出)后与GND Pad21连接。为了提高散热性,Ground Pad区域20可均匀打孔(图8未示出)。图8中,Ground Pad区域20可以采用铜皮制作,并可以通过螺丝孔22固定。这样,当有EMC能量时,能量可通过此电路损耗掉。
可选的,为了降低调整信号摆幅的难度,上述时序控制电路被配置为:根据摆幅调节表中误码率区间与目标摆幅值的对应关系,调整第M-1帧信号的摆幅包括:
时序控制电路被配置为:
根据摆幅调节表中误码率区间与目标摆幅值的对应关系,确定第M-1帧信号的误码率对应的目标摆幅值。
调整第M-1帧信号的摆幅值为第M-1帧信号的误码率对应的目标摆幅值。
可选的,时序控制电路还被配置为:
在第1帧信号的消隐阶段之前,存储摆幅调节表,其中,摆幅调节表包括多个误码率区间、多个目标摆幅值、误码率区间与目标摆幅值的对应关系。该摆幅调节表可以参考表1所示,表1以摆幅调节表包括4个误码率区间和4个目标摆幅值为例进行绘示。
本公开实施例提供了一种显示装置,包括:前述的时序控制器。
该显示装置可以是刚性的显示装置,也可以是柔性的显示装置(即可弯曲、可折叠);其类型可以是扭曲向列(Twisted Nematic,TN)型、垂直取向(Vertical Alignment,VA)型、平面转换(In-Plane Switching,IPS)型或高级超维场转换(Advanced Super Dimension Switch,ADS)型等液晶显示装置,还可以是有机发光二极管(Organic Light-Emitting Diode,OLED)显示装置以及包括这些显示装置的电视、数码相机、手机、平板电脑等任何具有显示功能的产品或者部件。
本公开的实施例提供了一种显示装置,该显示装置的显示画面好,抗电磁干扰性强,干扰性弱,用户体验佳。
本公开实施例提供了一种信号调整方法,应用于前述的时序控制器,时 序控制器包括接收电路和多个插损电路,接收电路被配置为接收N帧信号,参考图9所示,该方法包括:
S01、在第M帧信号的消隐阶段,检测第M-1帧信号的误码率。
S02、根据所述第M-1帧信号的误码率对应的目标摆幅值,调整所述第M-1帧信号的摆幅;
S03、根据第M-1帧信号的误码率对应的目标摆幅值,选择对应的插损电路,以损耗调整第M-1帧信号的摆幅所产生的能量;其中,M、N均为正整数,且1<M<N。
需要说明的是,上述S01-S03均在第M帧信号的消隐阶段完成,这样不影响正常显示。
可选的,S02、根据所述第M-1帧信号的误码率对应的目标摆幅值,调整所述第M-1帧信号的摆幅,可以包括:
S02a、确定第M-1帧信号的误码率,在预存的摆幅调节表中所属的误码率区间;以及
S02b、根据摆幅调节表中误码率区间与目标摆幅值的对应关系,调整第M-1帧信号的摆幅。
本公开的实施例提供了一种信号调整方法,采用该信号调整方法,可以在调整信号摆幅的同时,采用插损电路损耗调整信号摆幅所产生的能量,从而可以在提升输入信号质量的同时,降低因增强信号带来的EMC干扰。
可选的,S02b、根据摆幅调节表中误码率区间与目标摆幅值的对应关系,调整第M-1帧信号的摆幅包括:
根据摆幅调节表中误码率区间与目标摆幅值的对应关系,确定第M-1帧信号的误码率对应的目标摆幅值。
调整第M-1帧信号的摆幅值为第M-1帧信号的误码率对应的目标摆幅值。
可选的,在第1帧信号的消隐阶段之前,该方法还包括:存储摆幅调节表,其中,摆幅调节表包括多个误码率区间、多个目标摆幅值、误码率区间与摆幅值的对应关系。
可选的,第M帧信号的消隐阶段包括起始阶段、中间阶段和结束阶段。
在第M帧信号的消隐阶段,检测第M-1帧信号的误码率包括:
在第M帧信号的消隐阶段的中间阶段,检测第M-1帧信号的误码率。
由于在消隐阶段的起始阶段和结束阶段,一般还会进行其它信号处理。 在第M帧信号的消隐阶段的中间阶段进行检测,可以避免互相影响,提高检测的准确率。
下面具体说明如何调整第1帧信号的摆幅。参考图10所示,该方法包括:
S101、在第1帧信号的消隐阶段,设置第1帧信号对应的初始误码率区间和初始摆幅值。
S102、在第2帧信号的消隐阶段,检测第1帧信号的误码率。
S103、确定第1帧信号的误码率,在预存的摆幅调节表中所属的误码率区间。
S104、判断第1帧信号的误码率,在摆幅调节表中所属的误码率区间与初始误码率区间是否相同。
S105、若是,则将第1帧信号的摆幅调整至初始摆幅值,并选择初始摆幅值对应的插损电路,以损耗调整第1帧信号的摆幅所产生的能量。
S106、若否,则确定第1帧信号的误码率对应的目标摆幅值,将第1帧信号的摆幅调整至目标摆幅值,并选择与目标摆幅值对应的插损电路,以损耗调整第1帧信号的摆幅所产生的能量。
在S105或者S106之后,进行下一帧信号(即第2帧信号)的调整,具体方法包括:
S201、在第3帧信号的消隐阶段,检测第2帧信号的误码率。
S202、确定第2帧信号的误码率,在预存的摆幅调节表中所属的误码率区间。
S203、根据摆幅调节表中误码率区间与目标摆幅值的对应关系,确定第2帧信号的误码率对应的目标摆幅值;调整第2帧信号的摆幅值为第2帧信号的误码率对应的目标摆幅值。
S204、根据第2帧信号的误码率对应的目标摆幅值,选择对应的插损电路,以损耗调整第2帧信号的摆幅所产生的能量。
依此类推,直到将所有帧信号都调整完毕。第3帧到最后一帧信号的调整方法与第2帧信号的调整方法类似,这里不再详细说明。该信号调整方法属于自适应信号调整方法,可以实时调整信号质量,提升画面品质;同时,根据信号的目标摆幅值,同步采用插损电路损耗能量,降低EMC风险,减小面板干扰能力及增大其抗干扰能力。
