具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,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,都属于本发明保护的范围。
本发明的说明书和权利要求书及所述附图中的术语“第一”、“第二”等是用于区别不同对象,而不是用于描述特定顺序。此外,术语“包括”和“具有”以及它们任何变形,意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元,而是可选地还包括没有列出的步骤或单元,或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着,结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例,也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是,本文所描述的实施例可以与其它实施例相结合。
请参阅图1,本发明第一实施例提供一种显示面板10,显示面板10包括多条间隔设置的第一阳极线100、多条间隔设置的第二阳极线200和多个发光单元300,第一阳极线100和第二阳极线200交叉设置,相邻的两条第一阳极线100和相邻的两条第二阳极线200之间形成像素区域400。第一阳极线100和第二阳极线200交叉设置包括交叉相连接设置或者交叉不相接设置。在该实施例中,第二阳极线200设为在第一方向X上延伸,第一阳极线100设为在第二方向Y上延伸,所述第一方向X与第二方向Y呈预设夹角,在一些实施例中,所述预设夹角为90度夹角,在其他实施例中,所述预设夹角也可为0-90度中的任意值。在其他实施例中,第一阳极线100设为在第一方向X上延伸,第二阳极线200设为在第二方向Y上延伸。
发光单元300设置在像素区域400中,且发光单元300与形成像素区域400的两条第一阳极线100和两条第二阳极线200中的其中一条耦接,而从第一阳极线100或第二阳极线200接收发光电压。其中第一阳极线100或第二阳极线200用于为发光单元300提供发光电压。在该实施例中,发光单元300与第一阳极线100耦接,在其他实施例中,发光单元300也可以与第二阳极线200耦接,还可以将部分发光单元300与第一阳极线100耦接,另一部分发光单元300与第二阳极线200耦接。
显示面板10还包括至少一个调整结构500,用于调整目标发光单元600的发光亮度。其中当目标发光单元600为需要将发光亮度降低时,该调整结构500用于将目标发光单元的发光亮度降低。当目标发光单元600为需要将发光亮度升高时,该调整结构500用于将目标发光单元的发光亮度升高。
本发明提供的显示面板10中的调整结构500能够调整目标发光单元600的发光亮度,以使显示面板10中的发光单元300的发光亮度均匀。
在进一步的实施例中,发光亮度需调整的目标发光单元600为通过预先对至少一个未设置调整结构500的显示面板10进行至少一次测试得出的。其中测试的方法包括仿真测试或者实验手段测试。
在进一步的实施例中,调整结构500包括阻抗单元510,阻抗单元510耦接在第一阳极线100或者第二阳极线200与目标发光单元600之间,阻抗单元510具有预设阻值,用于调整提供至目标发光单元600的发光电压,以调整目标发光单元600的发光亮度。由于阻抗单元510具有预设阻值,其连接在第一阳极线100或者第二阳极线200与发光单元600之间,当第一阳极线100或第二阳极线200接收的发光电压流经阻抗单元510时,阻抗单元510会分掉预先提供给目标发光单元600的部分电压值,进而调整了目标发光单元600的实际发光电压,进而调整目标发光单元600的发光亮度。
请参阅图2,在进一步的实施例中,阻抗单元510包括至少一个阻抗条511,阻抗条511的两端分别与目标发光单元600及第一阳极线100或者第二阳极线200耦接。
可以理解的是,阻抗条511的设置形状不限于呈弯折回路或者螺纹回路设置。在图2中,示出了呈弯折回路的阻抗条511。
请参阅图3,本发明第二实施例提供一种显示面板10a,在显示面板10a中仅示出了阻抗单元510部分的示意图。在该实施例中,阻抗单元510包括至少两个阻抗条511,至少两个阻抗条511串联于目标发光单元600及第一阳极线100或者第二阳极线200之间。其中至少两个阻抗条511串联的方式不限。
在进一步的实施例中,至少两个阻抗条511层叠设置,例如,层叠设置于一电路板的不同层上,且相邻的两个阻抗条511之间设置有绝缘层,相邻的两个阻抗条511之间通过导电通孔512电连接。其中优选的,导电通孔512采用电阻值大于阻抗条511的材料制成。在其他实施例中,阻抗单元510可以包括更多个阻抗条511,且多个阻抗条511串联的方式不限。
请参阅图4,本发明第三实施例提供一种显示面板10b,在显示面板10b中仅示出了阻抗单元510部分的示意图。在该实施例中,阻抗单元510包括多个阻抗条511,分别为第一阻抗条511a、第二阻抗条511b、第三阻抗条511c、第四阻抗条511d以及第五阻抗条511e,阻抗条511两两之间具有绝缘介质层,相邻近的两个阻抗条511之间通过导电通孔512串联连接。例如,第一阻抗条511a与第二阻抗条511b之间通过导电通孔512a连接,第二阻抗条511b还与第三阻抗条511c之间通过导电通孔512b连接,第三阻抗条511c还与第四阻抗条511d之间通过导电通孔512c连接,第四阻抗条511d还与第五阻抗条511e之间通过导电通孔512d连接。如在其他实施例中还有更多的阻抗条511,阻抗条511之间的连接方式与上述类似,以使所述多个阻抗条511之间形成串联电路。可以理解的是,在本实施例中,导电通孔512的电阻值大于阻抗条,采用多个具有较大电阻值的导电通孔512在各阻抗条511之间,可以进一步增加阻抗单元510的电阻值,进而可以进一步的分压以调整目标发光单元600的发光亮度。
请参阅图5,本发明第四实施例提供一种显示面板10c,在显示面板10c中,调整结构500包括形成于目标发光单元600邻近的第一阳极线100或者第二阳极线200上的开口520,开口520用于将目标发光单元600邻近的第一阳极线100或者第二阳极线200打断。将第一阳极线100或者第二阳极线200打断,使得流经其邻近的发光单元600的发光电压改变,进而可以调整目标发光单元600的发光亮度。在该实施例中,是将第二阳极线200中打断形成开口520,在其他实施例中,开口520可以形成在第一阳极线100上,或者部分形成在第一阳极线100上,部分形成在第二阳极线200上。
在进一步的实施例中,每一第一阳极线100包括第一端110和第二端120,所有第一阳极线100的第一端110与第一电压节点A连接,所有第一阳极线100的第二端120与第二电压节点B连接。目标发光单元600与第一阳极线100或第二阳极线200的发光电压节点C连接,其中,第一电压节点A的电压大于第二电压节点B的电压。在该实施例中,目标发光单元600与第一阳极线100的发光电压节点C连接。
可以理解的是,显示面板10c在接入电压源后开始工作,本实施例中,将电压源设置在第一阳极线100的一端,所述的第一电压节点A是指提供给第一阳极线100电压的始端,所述的第二电压节点B是指电压流经第一阳极线100和第二阳极线200后的电压的末端。发光电压节点C是指目标发光单元600与第一阳极线100或者第二阳极线200连接的节点,用于为目标发光单元600提供发光电压。在其他实施例中,也可以将电压源设置在第二阳极线200的一端。
当目标发光单元600为发光亮度需要调高的发光单元300时,开口520设置在发光电压节点C与第二电压节点B之间的电流路径所经过的第一阳极线100或第二阳极线200中,以提高目标发光单元600的发光亮度。
请参阅图6和图7,以图6中为例来说明,将图6自第一电压节点A流经若干第一阳极线100和若干第二阳极线200达到发光电压节点C,再自发光电压节点C流径若干第一阳极线100和若干第二阳极线200达到第二电压节点B的电路转换为等效电路,其中图6中的第一阳极线100和第二阳极线200由于本身具有电阻,在等效电路中等效为电阻R1、R2、R3、R4以及R5,其中目标发光单元600等效为电阻RP。可以理解的是,根据电阻值大小的不同,若干第一阳极线100和若干第二阳极线200还可以等效为其他个数的电阻,在该实施例中,为了说明而等效为5个电阻。当开口520设置在发光电压节点C与第二电压节点B之间时,开口520靠近第二电压节点B处的电压节点记为开口电压节点O,也就是说开口电压节点O与第二电压节点B之间是没有电阻断开的,此时目标发光单元600位于开口电压节点O与第一电压节点A之间,而在开口电压节点O与第一电压节点A之间是有 第一阳极线100断开,即开口电压节点O与第一电压节点A之间的其中一个电阻断开,也就相当于将该电阻去掉,此时的等效电路如图7所示。从图7中可以看出,由于发光电压节点C与开口电压节点O之间的开口520,使得电阻R2去掉了,使得发光电压节点C与开口电压节点O之间并联的电阻变大,在第一电压节点A提供相同电压的情况下,使得目标发光单元600所对应的电阻RP对应的发光电压节点C的电压增大,进而使得目标发光单元600的发光亮度提高。
当目标发光单元600为发光亮度需要调低的发光单元300时,开口520设置在第一电压节点A与发光电压节点C之间的电流路径所经过的第一阳极线100或第二阳极线200中,以降低目标发光单元600的发光亮度。
请参阅8和图9,以图8中为例来说明,当开口520设置在第一电压节点A与发光电压节点C之间时,开口520靠近第二电压节点B处的电压节点记为开口电压节点O,也就是说开口电压节点O与第二电压节点B之间是没有电阻断开的,此时发光电压节点C位于开口电压节点O与第二电压节点B之间。而在开口电压节点O与第一电压节点A之间是有第一阳极线100或者第二阳极线200断开,即开口电压节点O与第一电压节点A之间的其中一个电阻断开,也就相当于将该电阻去掉,此时的等效电路如图9所示。从图9中可以看出,由于第一电压节点A与开口电压节点O之间的开口520,使得电阻R2去掉了,使得第一电压节点A与开口电压节点O之间并联的电阻变大,在第一电压节点A提供相同电压的情况下,使得第一电压节点A与开口电压节点O之间的电压分压变大,而使开口电压节点O与第二电压节点B之间的电压分压变小,由于目标发光单元600对应的电阻RP位于开口电压节点O和第二电压节点B之间,使得目标发光单元600所对应的电阻RP对应的发光电压节点C的电压变小,进而使得目标发光单元600的发光亮度降低。
请参阅图10,本发明第五实施例提供一种显示面板10d,第五实施例与第四实施例不同的是,在显示面板10d中,至少相邻两条第一阳极线100或者第二阳极线200中的开口520的位置相互错开。将开口520的位置相互错开设置,可以避免因局部区域内集中发光 亮度发生变化而使得整个显示面板10出现发光亮点或者发光暗点。
请参阅图11,本发明第六实施例提供一种显示面板10e,在显示面板10e中,调整结构500还包括为将目标发光单元600邻近的部分第一阳极线100或者第二阳极线200的电阻变大而形成的第一变形阳极单元700,和/或将目标发光单元600邻近的部分第一阳极线100或者第二阳极线200的电阻变小而形成的第二变形阳极单元800,进而调整与第一变形阳极单元700或者第二变形阳极单元800邻近连接的目标发光单元600的发光亮度。目标发光单元600邻近的因电阻变小或变大的变形阳极单元会影响该目标发光单元600的发光亮度。
在进一步的实施例中,第一变形阳极单元700通过将第一阳极线100或者第二阳极线200串联电阻条来得到。和/或将第一阳极线100或者第二阳极线200的宽度变细来得到。如图11中示出了将第一阳极线100的宽度变细来得到第一变形阳极单元700。请参阅图12,本发明第七实施例提供一种显示面板10f,在显示面板10f中,示出了将第一阳极线100串联电阻条R6来形成第一变形阳极单元700a。
在进一步的实施例中,第二变形阳极单元800通过将第一阳极线100或者第二阳极线200并联电阻条来得到。和/或将第一阳极线100或者第二阳极线200的宽度变宽来得到。如图11中示出了将第二阳极线200的宽度变宽来得到第二变形阳极单元800。在图12中示出了将第一阳极线100并联电阻条R7来形成第二变形阳极单元800a。
请参阅图13,在进一步的实施例中,当第二变形阳极单元800通过将第一阳极线100或者第二阳极线200并联电阻条来得到时,第一阳极线100或者第二阳极线200与其并联电阻条之间通过绝缘层900间隔开。在图13中示出了将第一阳极线100和电阻条R7通过绝缘层900来并联形成第二变形阳极单元800的示意图。
可以理解的是,上述实施例提供的多种调整结构500可以采用其中一种方式,也可以采用至少两个方式组合。如请参阅图14,本发明第八实施例提供一种显示面板10g,在显示面板10g中,调整结构500包括开口520、第一变形阳极单元700及第二变形阳极单元 800的组合形式。
请参阅图15,本发明还提供一种显示装置20,显示装置20包括如上述任一项的显示面板10。显示装置20可以为电视机、机器人、航空仪器、智能手机(如Android手机、iOS手机、Windows Phone手机等)、平板电脑、柔性掌上电脑、柔性笔记本电脑、移动互联网设备(MID,Mobile Internet Devices)或穿戴式设备等,或者可以为有机电致发光二极管(Organic light-emitting diodes,OLED)显示装置、有源矩阵有机发光二极管(Active Matrix Organic Light Emitting Diode,AMOLED)显示装置。
请参阅图16和图1,本发明还提供一种显示面板10的制备方法,显示面板10的制备方法包括步骤S100和步骤S200。详细步骤如下所述。
步骤S100,确定显示面板10的所有发光单元300中的发光亮度需调整的目标发光单元600。
步骤S200,为目标发光单元600设置调整结构500,以对目标发光单元600的发光亮度进行调整。其中调整结构500用于调整目标发光单元600的发光亮度。其中当目标发光单元600为需要将发光亮度降低时,该调整结构500用于将目标发光单元的发光亮度降低。当目标发光单元600为需要将发光亮度升高时,该调整结构500用于将目标发光单元的发光亮度升高。
本发明提供的显示面板10的制备方法中为需要调整发光亮度的目标发光单元600设置调整结构500,可以对目标发光单元600的发光亮度进行调整,进而提高制备得到显示面板10的发光显示的均匀性。
请参阅图17,在进一步的实施例中,“确定显示面板10的所有发光单元300中的发光亮度需调整的目标发光单元600”包括步骤S110、步骤S120和步骤S130。详细步骤如下所述。
步骤S110,获取显示面板10中的所有发光单元300的原始发光亮度。
步骤S120,根据原始发光亮度获得发光单元300的原始发光电压。
