Description

显示面板发光器件的连接电路 技术领域
本发明涉及显示技术领域，尤其涉及一种显示面板发光器件的连接电路。
 背景技术
AMOLED(Active-matrix organic light-emitting diode,主动矩阵有机发光二极体)显示面板与LCD(Liquid crystal display, 液晶显示器)相比具有自发光的独特优势，且具有能耗小、对比度高、色域广以及可折叠等具有竞争力的优点，已经成为目前的主流显示面板。
但是，目前大尺寸面板面临导线电位降(IR drop)导致的面板均一性下降的技术问题，且现有设计用于降低导线电位降的方案均有较大负面影响，如增大面板功耗，增加驱动IC成本等。
图1为现有AMOLED显示面板发光器件的导线电阻示意图，所述显示面板的分辨率为m*n，其中m代表发光器件阵列的行数，n代表发光器件阵列的列数。如图1所示，所述显示面板包括发光器件EL、第一导线Wa、第二导线Wb、第一电位端点VDD以及第二电位端点VSS，Ra代表第一导线Wa在特定位置的电阻值，Rb代表第二导线Wb在特定位置的电阻值。从图中可以看出，同一行的发光器件EL中，距离第一电位端点VDD与第二电位端点VSS较远的发光器件EL，相对于靠近第一电位端点VDD与第二电位端点VSS的发光器件EL，具有较大的导线电位降。举例来说，发光器件EL11的导线电位降是由于电阻值R11a与电阻值R11b所造成，EL12的导线电位降则是除了电阻值R11a与电阻值R11b之外，还要加上电阻值R12a与电阻值R12b所造成的效应，因此发光器件EL12的导线电位降会大于发光器件EL11的导线电位降，同理可知EL13的导线电位降会大于EL12的导线电位降。因此当与第一电位端点VDD和第二电位端点VSS的距离增加，发光器件EL的导线电位降也会随着增加，导致发光器件EL两端的电压差异变大，进而造成显示不均发生。
 技术问题
本发明提供一种显示面板发光器件的连接电路，以解决目前大尺寸面板面临导线电位降导致的面板均一性下降的技术问题，同时不造成增大面板功耗、增加驱动IC成本等负面影响。
 技术解决方案
为解决上述问题，本发明提供的技术方案如下：
本发明提供一种显示面板发光器件的连接电路，包括：多个发光器件，所述每一发光器件具有第一端与第二端，所述第一端电连接于第一导线，所述第二端电连接于第二导线；第一电位端点，设于所述显示面板的第一侧，经由所述第一导线电连接于所述发光器件的第一端；及第二电位端点，设于相对所述第一侧的第二侧，经由所述第二导线电连接于所述发光器件的第二端。
在本发明的至少一种实施例中，所述第一导线与所述第二导线单位长度的电阻值相同。
在本发明的至少一种实施例中，所述每一发光器件对应的所述第一导线与所述第二导线的长度总和相同。

在本发明的至少一种实施例中，所述发光器件的第一端为阳极，所述发光器件的第二端为阴极。
在本发明的至少一种实施例中，所述显示面板还包括第三侧以及第四侧，所述第一侧与所述第二侧分别位于所述显示面板的下侧与上侧，所述第三侧与所述第四侧分别位于所述显示面板的左侧与右侧，所述显示面板发光器件的连接电路还包括:覆晶薄膜，设于所述第一侧；外围走线，设于所述第一侧、所述第二侧、所述第三侧以及所述第四侧。
在本发明的至少一种实施例中，所述外围走线由所述覆晶薄膜引出，经由所述第三侧或所述第四侧进入所述第二侧，并与所述第二电位端点电连接。
在本发明的至少一种实施例中，所述第一电位端点电连接于所述覆晶薄膜。
在本发明的至少一种实施例中，所述显示面板为AMOLED显示面板。
在本发明的至少一种实施例中，所述第一电位端点为电源端点，所述第二电位端点为接地端点。
 有益效果
本发明提供的显示面板发光器件的连接电路采用第一电位端点与第二电位端点分别设于显示面板相对两侧的设计，使得每一发光器件的电流通路长度总和相等，进而使得面板内所有像素的发光器件两端因为有相同的导线电位降而具有一致的电压降，以解决目前大尺寸面板面临导线电位降导致的面板均一性下降的技术问题。
 附图说明
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。
下面结合附图，通过对本发明的具体实施方式详细描述，将使本发明的技术方案及其它有益效果显而易见。
附图中，
图1为现有AMOLED显示面板发光器件的导线电阻示意图；
图2为本发明显示面板发光器件的连接电路示意图；
图3为本发明显示面板发光器件的连接电路在显示面板上的走线示意图。
 本发明的实施方式
为更进一步阐述本发明所采取的技术手段及其效果，以下结合本发明的优选实施例及其附图进行详细描述。
本发明针对目前大尺寸面板面临导线电位降导致的面板均一性下降的技术问题，本实施例能够解决该缺陷。
图2为本发明显示面板发光器件的连接电路示意图，为了清楚说明本发明的连接电路，图2仅绘出一个发光器件，但实际上所述显示面板的分辨率为m*n。所述显示面板发光器件的连接电路包括:多个发光器件EL，所述每一发光器件EL具有第一端a与第二端b，所述第一端a电连接于第一导线Wa，所述第二端b电连接于第二导线Wb；第一电位端点VDD，设于所述显示面板的第一侧S1，经由所述第一导线Wa电连接于所述发光器件EL的第一端a；及第二电位端点VSS，设于相对所述第一侧S1的第二侧S2，经由所述第二导线Wb电连接于所述发光器件EL的第二端b。在一种实施例中，所述第一电位端点VDD为电源端点，所述第二电位端点VSS为接地端点，所述多个发光器件EL位于所述发光器件阵列的同一行。Ra代表第一导线Wa特定长度的电阻值，Rb代表第二导线Wb特定长度的电阻值。La代表第一导线Wa从第一电位端点VDD到发光器件EL第一端a的长度，Lb代表第二导线Wb从第二电位端点VSS到发光器件EL第二端b的长度。如图2所示，在一种实施例中，发光器件EL的第一端a为阳极，发光器件EL的第二端b为阴极，在面板点亮阶段，发光器件EL两端的电压差为
Vel=VDD-I*(Ra+Rb)-VSS
式中，I为通路电流，进一步细化后可得
Vel=VDD-I*Rsa*La-I*Rsb*Lb-VSS, L=La+Lb
式中Rsa与Rsb分别为第一导线Wa与第二导线Wb单位长度的电阻值。从式中可以看出，造成面板内各个像素的发光器件EL两端电压有所差异的原因为第一导线Wa与第二导线Wb单位长度的电阻值差异，以及对于各个发光器件EL，第一导线Wa与第二导线Wb在电流通路上的长度有所差异而导致。因此，在一种实施例中，所述第一导线Wa与所述第二导线Wb单位长度的电阻值相同，则公式演变为
Vel=VDD-I*L*Rs-VSS
此外，由于本发明的第一电位端点VDD设于所述显示面板的第一侧，所述第二电位端点VSS设于相对所述第一侧的第二侧，在一种实施例中，所述每一发光器件EL对应的所述第一导线Wa与所述第二导线Wb的长度总和相同。因为对于各个发光器件EL来说，第一导线Wa与第二导线Wb的长度总和相同，且第一导线Wa与第二导线Wb电阻率一致，所以各像素的Vel值一致，消除了导线电位降的影响，进而提高显示均一性。因此藉由将所述第一电位端点VDD与所述第二电位端点VSS设于显示面板的相对两侧，能够消除导线电位降的影响，相对于现有将电位端点设于显示面板同一侧的设计，可以提高显示均一性。
图3为本发明显示面板发光器件的连接电路在显示面板上的走线示意图，所述显示面板包括第一侧S1、第二侧S2、第三侧S3以及第四侧S4，所述第一侧S1与所述第二侧S2分别位于显示面板的下侧与上侧，所述第三侧S3与所述第四侧S4分别位于显示面板的左侧与右侧。所述显示面板发光器件的连接电路还包括:覆晶薄膜(COF)，设于所述第一侧S1；及外围走线VSSr，设于所述第一侧S1、所述第二侧S2、所述第三侧S3以及所述第四侧S4。在一种实施例中，所述外围走线VSSr由所述覆晶薄膜COF引出，经由所述第三侧S3或所述第四侧S4进入所述第二侧S2，并与所述第二电位端点VSS电连接。在一种实施例中，所述第一电位端点VDD电连接于所述覆晶薄膜COF。因此对于显示面板上任一像素的发光器件EL而言，第一导线Wa与第二导线Wb的长度总和相同，且第一导线Wa与第二导线Wb电阻率一致，所以各像素的Vel值一致，消除了导线电位降的影响，进而提高显示均一性。
有益效果：本发明提供的显示面板发光器件的连接电路采用第一电位端点与第二电位端点分别设于显示面板相对两侧的设计，使得每一发光器件的电流通路长度总和相等，进而使得面板内所有像素的发光器件两端因为有相同的导线电位降而具有一致的电压降，以解决目前大尺寸面板面临导线电位降导致的面板均一性下降的技术问题。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本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。
