【具体实施方式】
本发明公开一种 OLED画素结构及 OLED面板,所述 OLED面板包括基板 和蒸镀在基板上的画素, 作为本发明画素结构的实施例, 如图 2至 8所示, 第 一基准电压用 VDD表示, 第二基准电压用 VSS表示, 第一接口用 P1表示,第二 接口用 P2表示; 所述画素包括多个平行布置的有色发光区域, 本实施例具体为 R (红色)、 G (绿色)、 B (蓝色)三种, 每种颜色的有色发光区域又被分为第 二区域 2、 第一区域 1和第三区域 3 , 第二区域 2与第一区域 1、 第二区域 2与 第三区域 3之间均设有间距, 所述第一区域 1、 第二区域 2和第三区域 3的阳极 通过开关管 (TFT )与第一基准电压 (VDD )连接, 第一区域 1 的阴极连接到 第一接口 (PI ), 第二区域 2 的阴极连接到第二基准电压 (VSS ), 第三区域 3 的阴极连接到第二接口 (P2 ); 当第一区域 1发生混色时, 使第一接口 (P1 )与 第一基准电压 (VDD )连接, 当第一区域 1未发生混色时, 使第一接口 (P1 ) 与第二基准电压(VSS )连接; 当第三区域 3发生混色时, 使第二接口 (P2 )与 第一基准电压 (VDD )连接, 当第三区域 3未发生混色时, 使第二接口 (P2 ) 与第二基准电压 (VSS )连接。
如图 4所示, 以红色发光区域为例, 当第一区域 1发生混色时, 使第一接
口 (PI)与第一基准电压 (VDD)连接, 当第一区域 1未发生混色时, 使第一 接口 (P1)与第二基准电压(VSS)连接; 如图 6所示, 当第三区域 3发生混色 时, 使第二接口 (P2)与第一基准电压 (VDD)连接, 当第三区域 3未发生混 色时, 使第二接口 (P2)与第二基准电压 (VSS)连接。
如图 8所示, 该线路图是阵列为 2*2的画素中红色发光区域的线路图, 所 述 OLED面板包括多工器 4, 所述第一接口 (P1)和第二接口 (P2)通过所述 多工器 4选择性地与第一基准电压 (VDD)或第二基准电压 (VSS)连接。 利 用所述多工器, 可以使第一接口 (Pl)、 第二接口 (P2)在第一基准电压(VDD) 和第二基准电压 (VSS)之间进行切换。
本发明把画素的每种颜色的有色发光区域进行了分割, 并减小相邻不同颜 色的有色发光区域的间距 D2,由于不同颜色有色发光区域的第二区域间距较大, 一般大于 30μηι, 红色发光区域的第二区域与绿色发光区域的第一区域一般大于 15μηι, 所以所有颜色的有色发光区域的第二区域都不会发生混色, 只有第一区 域或第三区域才有可能会发生混色现像, 第二区域的阳极通过开关管(TFT)与 第一基准电压(VDD)连接, 第二区域的阴极连接到第二基准电压(VSS), 所 以始终能够正常工作;当第一区域和第三区域均未发生混色时,使第一接口( Ρ 1 ) 和第二接口 (Ρ2)与第二基准电压(VSS)连接, 第一区域和第三区域都能够正 常工作。
当第一区域发生混色时, 使第一接口 (P1)与第一基准电压(VDD)连接, 第一区域连接的电极就无电流通过, 第一区域就不会发光; 同理, 当第三区域 发生混色时, 使第二接口 (Ρ2)与第一基准电压 (VDD)连接, 第三区域连接 的电极就无电流通过, 第三区域就不会发光, 所以保证了画素具有较高的色纯 度, 又由于蒸镀掩膜板在对位时一般情况下要么向左侧偏, 要么向右侧偏, 所 以第一区域和第三区域至少有一侧是无混色的, 从而提高 OLED面板画素的开 口率。
为了最大幅度地提高 OLED面板画素的开口率, 同种颜色有色发光区域的
第二区域与第一区域、 第二区域与第三区域之间的间距 D1 越小越好,但又不能 导通,现有技术中可以做到的 D1最小尺寸为 3μηι,由于考虑到设备精度及良率, 一般要求 3μηι Dl 5 m。 同理,所述相邻的不同颜色有色发光区域之间的间 距为 D2, 5μηι < D2 < ΙΟμηι, 而第一区域和第三区域的宽度为 Η, 5μηι < Η < 9·5μηι。
下面以 Dl = 3μηι, D2 = 5μηι进行计算, 支设现有技术中不同颜色发光区 域之间的间距 Ο0 = 30μηι, 可以得出第一区域的宽度和第三区域的宽度分别为 9.5μηι, 具体计算方法为11 = ( D0-2*D1-D2 ) /2, 这是在现有技术的基础上新增 加的发光区域面积。
下面以 D1 = 5μηι, D2 = ΙΟμηι进行计算, 支设现有技术中不同颜色发光区 域之间的间距 Ο0 = 30μηι, 可以得出第一区域的宽度和第三区域的宽度分别为 5μηι, 这是在现有技术的基础上新增加的发光区域面积。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明, 不 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通 技术人员来说, 在不脱离本发明构思的前提下, 还可以做出若干筒单推演或替 换, 都应当视为属于本发明的保护范围。
