本申请实施例提供一种栅电极驱动设计方法、装置及电子设备,以下分别进行详细说明。
首先介绍本申请实施例中栅电极驱动设计方法,该栅电极驱动设计方法在电子设备中执行。电子设备可以是台式终端或移动终端,电子设备具体还可以是手机、平板电脑、笔记本电脑等中的一种。
该栅电极驱动设计方法包括:获取用户配置的显示面板的设计尺寸信息及显示面板的设计分辨率信息;根据所述显示面板的设计尺寸信息和所述设计分辨率信息,在预设的绘制空间中,确定所述显示面板区域中GOA器件可用绘图空间的位置信息;获取用于当前栅电极驱动设计的目标时钟驱动信息,所述目标时钟驱动信息用于限定当前GOA器件中使用时钟驱动信号的目标数量;基于所述目标时钟驱动信息,在预设的多种GOA设计策略信息中,确定用于当前栅电极驱动设计的目标GOA设计策略信息;基于所述目标GOA设计策略信息,在所述GOA器件可用绘图空间中,绘制GOA器件图案。
GOA是Gate on Array的简写,本申请中栅电极驱动智能设计即为GOA器件设计,GOA技术,是运用显示面板的原有制程将水平扫描线的驱动电路制作 在显示区周围的基板上(形成GOA器件),使之能替代外接IC来完成水平扫描线的驱动。GOA技术能减少外接IC的绑定(bonding)工序,有机会提升产能并降低显示面板成本,而且可以使液晶显示面板更适合制作窄边框或无边框的显示显示面板。
如图1所示,为本申请实施例中栅电极驱动设计方法的一个实施例示意图,该方法包括:
101、获取用户配置的显示面板的设计尺寸信息及显示面板的设计分辨率信息。
本申请实施例中,当设计人员(用户)需要栅电极驱动设计的时候,可以预先配置好需要设计的显示面板的设计尺寸信息及显示面板的设计分辨率。具体的,此处用户配置可以是用户输入。例如可以是用户在进入栅电极驱动设计方法对应的程序中,点击预设设计菜单或者自动弹出显示面板的设计尺寸信息及显示面板的设计分辨率的输入界面,当用户输入相关参数之后,即获取到获取用户配置的显示面板的设计尺寸信息及显示面板的设计分辨率。
例如,当前栅电极驱动设计对应的显示面板的设计尺寸55’UHD(Ultra High Definition),有效显示区域的对角线长138731.517152,显示面板的设计分辨率为2160*3840。
102、根据所述显示面板的设计尺寸信息和所述设计分辨率信息,在预设的绘制空间中,确定所述显示面板区域中GOA器件可用绘图空间的位置信息。
是在本申请实施例中,该栅电极驱动设计方法的执行流程可以是以插件的形式加载在显示面板设计程序中,也可以是独立于显示面板设计程序之外的栅电极驱动智能设计程序,只要能在显示面板设计程序中采集用户当前设计操作对应的显示面板设计参数即可,具体此处不作限定。
其中,显示面板设计程序可以是现有的显示面板设计的电子设计自动化(Electronics Design Automation,EDA)程序,例如Protel、Altium Designer、PSPICE、OrCAD等。
其中,预设的绘制空间可以栅电极驱动设计方法对应的设计程序或设计插件的初始设计空间,例如EDA中进行栅电极驱动智能设计时的设计空间。
103、获取用于当前栅电极驱动设计的目标时钟驱动信息。
其中,所述目标时钟驱动信息用于限定当前GOA器件中使用时钟驱动信号的目标数量,时钟驱动信号的目标数量用于确定GOA驱动级数,例如,时钟驱动信号的目标数量为4个,8个,12个等,分别对应GOA驱动级数为4CK、8CK、12CK等。具体的,本申请实施例中,可以预设的多种时钟驱动信息,获取用于当前栅电极驱动设计的目标时钟驱动信息的方式可以是:在预设的多种时钟驱动信息中,获取用户选择的用于当前栅电极驱动设计的目标时钟驱动信息。可以理解的是,在本申请其他一些实施例中,获取用于当前栅电极驱动设计的目标时钟驱动信息,也可以是自动确定用于当前栅电极驱动设计的目标时钟驱动信息,即自动确定GOA驱动级数,例如,GOA驱动级数(时钟驱动信号的目标数量)可以综合充电率,RC加载情况,Q点充电情况等自动确定。
104、基于所述目标时钟驱动信息,在预设的多种GOA设计策略信息中,确定用于当前栅电极驱动设计的目标GOA设计策略信息。
一般来说,显示面板的规格,很难有一个完全的定义,因为显示面板对于消费者而言更多的是主观的感觉,不同厂商提供的显示面板规格,也会有所差别,但是对设计者而言,需要把客户的要求、厂商的要求转化成客观量化的数据作为设计的目标,也就是要转化成可设计的规格,即设计规格(专业规格)。本申请实施例中预置的显示面板的GOA设计策略,即为预先设置的显示面板的GOA设计规范或GOA设计规格,以便设计人员在设计时,基于用户配置的显示面板GOA设计数据,自动后续根据GOA设计策略绘制GOA器件图案。
本申请实施例中,在步骤103中获取目标时钟驱动信息(时钟驱动信号数量)之后,即确定了GOA驱动级数,基于所述目标时钟驱动信息,在预设的多种GOA设计策略信息中,确定符合GOA驱动级数(时钟驱动信号数量)的目标GOA设计策略信息,该目标GOA设计策略信息即用于当前栅电极驱动设计的GOA设计策略信息。
GOA驱动级数的确定,可以根据对显示面板充电能力需求选择,若对充电要求很高,可考虑更高的GOA驱动级数,例如选择12CK驱动级数,反之亦然。
105、基于所述目标GOA设计策略信息,在所述GOA器件可用绘图空间中,绘制GOA器件图案。
本申请在显示面板栅电极驱动设计阶段,在预设的绘制空间中,基于用户的配置信息自动确定GOA器件可用绘图空间的位置信息和目标GOA设计策略信息,实现在GOA器件可用绘图空间中快速绘制GOA器件图案,降低对设计人员的设计经验依赖性,无需设计人员手动计算设计参数,缩短显示面板设计时长和评估时间,快速产出符合需求的栅极驱动设计,提升研发效率,节省人力资源和成本。
需要说明的是,本申请实施例中显示面板可以是各种类型的显示面板,例如液晶显示(Liquid Crystal Display,LCD)面板、有机发光二极管(OrganicLight-Emitting Diode,OLED)显示面板等,具体的,如薄膜晶体管液晶显示面板(Thin Film Transistor-Liquid Crystal Display,TFT-LCD)等。
在本申请一些实施方式中,如图2所示,所述根据所述显示面板的设计尺寸信息和所述设计分辨率信息,在预设的绘制空间中,确定所述显示面板区域中GOA器件可用绘图空间的位置信息,包括:
201、基于所述显示面板的设计尺寸信息及显示面板的设计分辨率信息,确定所述显示面板区域的位置信息和所述显示面板中有效显示区域的位置信息。
由于显示面板的设计尺寸一般为显示面板斜对角线的长度,此时,所述显示面板的设计尺寸信息包括所述显示面板中有效显示区域的对角线长,例如55’UHD的有效显示区域的对角线长138731.517152um。
步骤201中基于所述显示面板的设计尺寸信息及显示面板的设计分辨率信息,确定所述显示面板区域的位置信息和所述显示面板中有效显示区域的位置信息,可以包括:基于所述显示面板的设计尺寸信息及显示面板的设计分辨率信息,直接随机在在预设的绘制空间中,确定矩形的显示面区域的位置信息,获取所述显示面板长宽比;按照三角形勾股定理,根据所述显示面板长宽比、所述显示面板中有效显示区域的对角线长,计算所述显示面板中有效显示区域的长度和宽度;根据所述显示面板中有效显示区域的长度和宽度,以及所述显 示面板的设计分辨率信息,确定显示面板区域中有效显示区域的位置信息。
其中,显示面板的长宽比(Style)一般是固定的,如16:9,也会有个别设计变动,如21:9,可以获取用户输入的显示面板长宽比。
下面结合具体示例说明一下如何基于所述显示面板的设计尺寸信息及显示面板的设计分辨率信息,确定所述显示面板区域的位置信息和所述显示面板中有效显示区域的位置信息。
显示面板的设计尺寸:Size(对角线长,单位:英寸);显示面板的长宽比:Style;显示面板的设计分辨率:Reso(Resolution),单个像素尺寸:pixel长(A),pixel宽(B);
由如下公式计算可得到有效显示区域的长(Length)、宽(Width):
Length 2+Width 2=Size 2
Figure PCTCN2020108622-appb-000001
Length=Width*Style
根据有效显示区域的长(Length)、宽(Width),例如:55’UHD(对角线138731.517152)长宽比16:9,根据三角形勾股定理算出有效显示区域的长宽分别为1209600um和680400um,有效显示区域的长宽确定之后,即可确定显示面板中有效显示区域的位置信息。
此外,设计分辨率为2160*3840,单个像素尺寸的也可以计算出来:pixel长(A)=680400/2160=315um;pixel宽(B)=1209600/3840/3(RGB)=105um。
202、获取用户配置的显示面板的边框区域的位置信息。
在进行栅电极驱动设计时,可以是用户直接输入配置显示面板的边框区域的位置信息,即显示面板的border,栅电极驱动设计装置可以获取用户配置的显示面板的边框区域的位置信息。
203、根据所述边框区域的位置信息和所述有效显示区域的位置信息,在所述显示面板区域中确定GOA器件可用绘图空间的位置信息。
在确定显示面板的边框区域的位置信息和显示面板中有效显示区域的位置信息,即可确定显示面板的边框区域和显示面板中有效显示区域之间的区域为GOA器件可用绘图空间的位置信息。

(5)根据多个GOA单元对应的GOA单元可用绘图空间的位置信息,在所述显示面板区域中确定矩形状的所述GOA器件可用绘图空间的位置信息。
在一个具体实施例中,GOA unit(GOA单元)高度A:显示面板像素(pixel)尺寸的高度(即位于第n个pixel gate到n+1个pixel gate之间的距离,与显示面板尺寸有关)
2、GOA Unit长度B:依据boder尺寸确定,通过预估WOA信号走线,bussline走线,距离AA区的距离,确定可栅驱动电极layout空间,定义为GOA unit边界,整个显示面板的栅电极GOA驱动有GOA unit循环阵列而成,首先自动完成单足GOA unit。
在本申请一些实施方式中,所述目标GOA设计策略信息中包括GOA单元的电路图信息,以及多个GOA单元的布局信息;此时,所述步骤105中所述基于所述目标GOA设计策略信息,在所述GOA器件可用绘图空间中,绘制GOA器件图案,可以包括:根据所述GOA单元的电路图信息,在每个GOA单元可用绘图空间,分别绘制每个GOA单元的设计图案;根据所述多个GOA单元的 布局信息,绘制所述多个GOA单元的阵列图案。
在本申请一些实施方式中,所述多个GOA单元电路结构相同,所述GOA单元的电路图信息为多个GOA单元相同的电路图信息;所述根据所述GOA单元的电路图信息,在每个GOA单元可用绘图空间,分别绘制每个GOA单元的设计图案,包括:根据所述GOA单元的电路图信息,绘制所述多个GOA单元的共有设计图案;在每个GOA单元可用绘图空间,分别填入所述共有设计图案中,实现绘制每个GOA单元的设计图案。
在本申请一些实施方式中,所述根据所述GOA单元的电路图信息,绘制所述多个GOA单元的共有设计图案,包括:确定所述GOA单元的电路图信息中各电路设计对象的信息,所述电路设计对象包括元器件和电路连接线;根据所述显示面板的设计尺寸信息,在预置的显示面板电路设计对象的尺寸数据库中,查找所述各电路设计对象的参考尺寸信息;根据所述参考尺寸信息,确定所述各电路设计对象的尺寸信息;根据所述各电路设计对象的尺寸信息,绘制所述多个GOA单元的共有设计图案。
本申请实施例中,各电路设计对象可以是GOA单元中各种电路设计对象,例如TFT。如图3所示,为GOA驱动级数8CK的GOA电路示意图,8CK的GOA一般由如图4所示的TFT组成(T11~T44)。
由于多个GOA单元可能是相同的,下面以GOA unit部分TFT绘制和空间摆放为例,说明根据所述各电路设计对象的尺寸信息,绘制所述多个GOA单元的共有设计图案的过程,具体如下:
T11自动layout:W/L已知,卡控上下unit间距,右侧走线与GOA unit边界对齐,M2走线,M1间距对位可根据预设的GOA设计策略信息对位,具体见如下参考值:
1、单颗TFT source/drain/channel length尺寸(如A=5um/B=6um/C=4.5um),输入W/L自动绘制T11图案,如W/L=3800/6,注意TFT两端source宽度与中间位置source相比,需补值(如此例宽度为6um=A+1um,GOA TFT均需如此)。
2、T11走线线宽D=12um,两组GOA unit线距E=14um,M2走线距M1间距G=6um;
3、TFT摆放可水平、或双排对顶设置,具体取决于摆放空间;
4、TFT M2/halftone距离底层M1的间距可单独调节(例如上下左右均设置为F=6um)。
T43自动layout:T43通过GOA unit左侧、上下间距卡控,以T33为基准;
1、单颗TFT source/drain/channel length尺寸(如A=5um/B=6um/C=5.5um),输入W/L自动生成T43,如W/L=650um/7um;
2、T33、T43TFT对顶排列设计,Half tone to halftone距离为走线线宽M=12um;
3、T33、T43距离GOA Unit上下左距离分别D,E,H,I,N,举例D=625um,E=38um,H=45um,I=625um,注意M1之间间距N=10um。
需要说明的是,上述两个TFT(T11、T43)的绘制仅为举例,GOA单元中的其他TFT可以参照类似过程进行绘制,具体此处不作限定。
具体的,在根据所述参考尺寸信息,确定所述各电路设计对象的尺寸信息时,可以先根据所述参考尺寸信息,确定所述各电路设计对象的第一尺寸信息,对所述第一尺寸信息进行GOA绘图模拟,若不符合预设的功能要求(如预设模电参数要求或者预设Pixel CR要求等),重新调整所述各电路设计对象的尺寸信息,直至GOA绘图模拟符合预设的功能要求为止,此时,即确定符合预设的功能要求的各电路设计对象的尺寸信息。
在一个具体实施例中,假设第一次GOA layout(GOA绘图模拟):
(1)根据参考尺寸信息,先自动计算的各TFT尺寸如图4所示:
(2)自动填入模电参数表,模拟Q/G波形及各关键参数:
假设此时Q(N)/G(N)点波形评价:选取第49级Q(N)/G(N)波形。假设Pixel CR评价:特定错充电压下,单点CR只有80.28%,不满足设计要求,表示pixel明显充电不足。
此时,可调整与之相关的TFT尺寸,如增加T21/T11的TFT尺寸,再次进行各电学参数模拟,进行自动GOA layout效果评价。
第二次GOA layout:
如图5所示,增加T21/T11的TFT尺寸,GOA layout空间满足,然后继续进 行电学评价:
Q(N)/G(N)点波形评价:选取第49级Q(N)/G(N)波形,Q(点)波形拉起正常,续传OK,G(N)点波形正常;
Pixel CR评价:特定错充电压下,单点CR可达89.58%,再次评价OC九点充电率:充电波形,pixel CR和CR U%均符合需求,进一步评价Vth/工作温度margin等:如Vth在负飘-8V时,Q点拉升困难,后续传级和充电不足,但满足-5V传级OK,在正飘+6V时,传级NG,4V时传级OK,因此Vth漂移电压范围是-5V~4V,漂移特性满足设计要求,确定当前GOA中各电路设计对象的尺寸信息。
在本申请另一些实施方式中,所述多个GOA单元包括两种电路结构,所述多个GOA单元包括至少一个第一GOA单元和至少一个第二GOA单元,所述GOA单元的电路图信息包括第一GOA单元对应的第一电路图信息以及第二GOA单元的第二电路图信息,所述第一GOA单元和所述第二GOA单元没有交集。
此时,所述根据所述GOA单元的电路图信息,在每个GOA单元可用绘图空间,分别绘制每个GOA单元的设计图案,包括:根据所述第一电路图信息,绘制所述第一GOA单元的第一共有设计图案;根据所述第二电路图信息,绘制所述第二GOA单元的第二共有设计图案;在每个第一GOA单元可用绘图空间,分别填入所述第一共有设计图案,实现绘制第一GOA单元的设计图案;在每个第二GOA单元可用绘图空间,分别填入所述第二共有设计图案,实现绘制第二GOA单元的设计图案。
在本申请一些实施方式中,所述根据所述多个GOA单元的布局信息,绘制所述多个GOA单元的阵列图案,包括:根据所述显示面板的设计尺寸信息,绘制所述目标数量的时钟驱动图案;将多个GOA单元中首端目标数量的GOA单元与所述目标数量的时钟驱动图案对位;绘制虚拟TFT和虚拟电容,将所述虚拟TFT与多个GOA单元中第一级GOA单元对位,将所述虚拟电容将与所述多个GOA单元中最后一级GOA单元对位。
在本申请一些实施方式中,根据所述显示面板的设计尺寸信息,绘制所述 目标数量的时钟驱动图案,包括:根据所述显示面板的设计尺寸信息,在预置的显示面板时钟驱动图案的尺寸数据库中,查找所述时钟驱动图案的参考尺寸信息;根据所述时钟驱动图案的参考尺寸信息,确定所述各时钟驱动图案的尺寸信息;根据各时钟驱动图案的尺寸信息,所述目标数量的时钟驱动图案。
在本申请一些实施方式中,所述多种GOA策略信息中包括多种不同数量时钟驱动信号的GOA策略信息;所述基于所述目标时钟驱动信息,在预设的多种GOA设计策略信息中,确定用于当前栅电极驱动设计的目标GOA设计策略信息,包括:根据所述目标数量时钟驱动信号的时钟驱动信息,在预设的多种GOA设计策略信息中,确定目标数量时钟驱动信号对应的目标GOA设计策略信息。
在一个具体实施例中,据所述多个GOA单元的布局信息,绘制所述多个GOA单元的阵列图案可以包括如下过程:
(1)GOA 器件首/尾部分TFT layout和空间摆放:
1、GOA 器件首端设计:GOA器件首端(前8级GOA unit,即CK1~CK8设计),前八级同GOA unit对位方法,增加的dummy TFT以已经确定的Vss+第一级GOA unit对位。
2、GOA器件尾端设计:参考最后一级GOA circuit&Vss位置,Dummy电容C_end依据4th GOAunit&VSS对位,STV&reset绕线电阻通过VSS对位。
(2)bussline&Via(过孔)layout和空间摆放:
1、Busline自动layout:以GOA unit边界和TFT glass定位;以对应一组GOA unit的busline作为最小circuit单元
2、via hole自动layout(实现信号传递,搭接不同层metal作用):via距离M1边缘距离作为参考,一般via尺寸可调(长方形或正方形或八角形);可识别出via hole深浅孔设计:GOA区&busline区的via hole均为深浅孔设计,深浅孔的选择与各TFT的摆放方式及信号接入位置有关,自动识别。
3、GOA circult自动layout:使用pixel的gate接入位置进行对位,根据分辨率确定GOA unit组数;例如分辨率1920*1080,GOA circult循环组数=1080组, 整个GOA器件部分的组成=GOA circult(和显示面板设计分辨率及尺寸匹配)+4级尾端dummy GOA,至此GOA各模块pre-layout自动实现完成。
4、GOA各级电路自动连接,根据spice搭建的电路模型,实现GOA pre-layout各模块的信号的自动连接。
5、调用预设的design rule检查模块:检查自动绘制layout是否符合规范,若break rule则自动修正pattern。
6、自动提取栅电极各模块RC loading,写入模电参数表simulation file GOA RC部分:CK1-CK8,LC1/LC2,Vss,STV,Data,信号的初始Timing及电压可根据输入的刷新率自动生成。
7、调用电路模拟模块,评价GOA器件设计各关键参数margin,如CR,feedthrough,Q点/N点波形评价,Vth正飘/负飘margin,工作温度margin等。
8、判断栅电极GOA设计符合显示面板设计标准:根据预定的各评价参数target值得min/max范围,判断自动设计的GOA layout是否符合设计标准。若符合,输出栅电极layout图档和各参数评价结果。
9、若不符合显示面板设计标准:自动进行GOA的优化迭代,主要通过调整TFT size及各颗TFT的相互搭配性,考虑电路功耗,反复迭代直至筛选出最优组合。
通常,为了使得设计出来的显示面板在各种情况下都能够满足驱动原理的要求,采用的设计观念是“最坏情况设计”,即在设计时考虑在极限情况下能够使用,那么其他情形就没有问题。比如画面的帧频在60~75Hz,则以75Hz考虑充电时间,而以60Hz考虑电荷保持时间,这样在两个极限条件下如果能够满足,其它频率下肯定能够满足。因此,在本申请实施例中也采用类似的原则,上述部分具体实施例中,仅列出单一数值的,表示该单一数值中的值为最坏情况的设计值,相对该设计值为好的方向即满足设计要求。
需要说明的是,上述实施例中GOA设计策略中仅为GOA设计策略中的部分策略举例,可以理解的是,除了上述举例的GOA设计策略之外,本申请实施例中,GOA设计策略还可以根据实际需要包括任何其他更多的GOA设计策略,例如更多时钟驱动信号的GOA设计策略等,本申请实施例中不再详细赘 述,任何基于设计规范的GOA设计策略都可以基于本申请的发明思想采用,具体此处不作限定。
另外,在实际应用过程中可以针对不同的显示面板,设置不同的显示面板的设计策略,而为了达到显示面板的某一特性的最优,在相关显示面板设计策略上,可以采用设置更多的设计参数,以间接提高显示器分辨率,满足显示器更高分辨率的设计要求。
由于显示面板技术一直在进步,显示面板的设计规范也一直在更新,因此,后续由于制程精进和设计优化等原因,GOA设计规范如果有更新,可以同步更新显示面板的GOA设计策略,具体的,在本申请一些实施例中,所述栅电极驱动设计方法还可以包括:获取显示面板更新的GOA设计策略,所述更新的GOA设计策略包括GOA器件中至少一结构的GOA设计策略,或者至少两个GOA结构之间的对应关系;基于所述更新的像GOA设计策略,更新所述显示面板的GOA设计策略。后面可以基于更新后的显示面板的GOA设计策略,进行新的GOA单元或GOA器件的图案绘制。
