一种制造有机发光显示器的设备以及制造方法
【技术领域】
本发明涉及有机发光显示器的制造领域，尤其涉及一种制造有机发光显示器的设备以及制造方法。
【背景技术】
在屏幕上显示各种信息的显示器是信息和电信时代的核心技术，并且显示器发展成为更薄、更轻、便携式的且高性能的显示器。因此，可克服阴极射线管（CRT）的各种缺点（即重量和体积）的平板显示器（如有机发光显示器）吸引了大量注意。有机发光显示器为在电极之间使用薄有机发光层的自发光装置。有机发光显示器可制成和纸一样薄。根据产生光的有机发光层的材料，可将有机发光显示器分为小分子有机发光显示器和聚合物有机发光显示器。通常，小分子有机发光显示器的有机发光层通过真空淀积形成薄膜，而聚合物有机发光显示器的有机发光层利用溶液涂渍法（旋涂或喷墨打印）形成为薄膜。
当发光层通过喷墨打印形成时，墨汁经喷嘴喷出后有一个沿着喷嘴移动方向的均匀速度，同时有一个向下的加速度g向下加速运动，因此墨汁会做平抛或者斜抛运动，因此在进行喷墨时，喷嘴里的墨水需要提前一定的距离下落，使得墨水滴落在像素区域中央的误差较大，可能会造成滴落其他位置或其他像素的风险。
【发明内容】
本发明主要解决的技术问题是提供一种制造有机发光显示器的设备以及制造方法，以降低墨水由于水平方向的运动而滴落其他位置或其他像素的风险。
为解决上述问题，本发明提供了一种有机发光显示器的制造方法，包括如下步骤：控制喷头与衬底进行相对移动；当喷头移动到衬底的表面的预定区域时，控制喷头上的至少一喷嘴喷出墨水，其中在喷嘴喷出墨水的过程中，喷嘴对墨水的喷出速度在衬底的表面的平行方向上具有第一速度分量，喷头和衬底的相对移动速度在平行方向上具有第二速度分量，第一速度分量和第二速度分量互为反向；
其中，在控制喷头与衬底进行相对移动的步骤中：
控制喷头沿平行方向与衬底进行相对移动；
其中，在当喷头移动到衬底的表面的预定区域时，控制喷头上的至少一喷嘴喷出墨水的步骤中：
控制第一速度分量和第二速度分量的大小相同，以使得喷嘴喷出的墨水在平行方向上与所述衬底保持相对静止。
为解决上述技术问题，本发明提供一种有机发光显示器的制造设备，包括：喷头，用于放置在衬底之上并包括至少一喷嘴，喷嘴用于向衬底的表面喷出墨水；移动单元，用于控制喷头与衬底进行相对移动；其中，在喷嘴喷出墨水的过程中，喷嘴对所述墨水的喷出速度在衬底的表面的平行方向上具有第一速度分量，喷头和衬底的相对移动速度在平行方向上具有第二速度分量，第一速度分量和所述第二速度分量互为反向。
其中，第一速度分量和第二速度分量的大小相同，以使得喷嘴喷出的墨水在平行方向上与衬底保持相对静止。
其中，移动单元控制喷头沿平行方向与衬底进行相对移动。
其中，喷嘴包括喷嘴本体以及和喷嘴本体相连接的弯折部，墨水经喷嘴本体从弯折部输出，喷嘴本体垂直于衬底的表面，弯折部与喷嘴本体的夹角大于0度且小于180度，弯折部相对于喷嘴本体的弯折方向与喷嘴与衬底的相对移动方向相反。
其中，喷嘴弯折部与喷嘴本体的夹角为90度。
为了解决上述问题，本发明还提供了一种有机发光显示器的制造方法，包括如下步骤：控制喷头与衬底进行相对移动；当喷头移动到衬底的表面的预定区域时，控制喷头上的至少一喷嘴喷出墨水，其中在喷嘴喷出墨水的过程中，喷嘴对墨水的喷出速度在衬底的所述表面的平行方向上具有第一速度分量，喷头和衬底的相对移动速度在平行方向上具有第二速度分量，第一速度分量和第二速度分量互为反向。
其中，在控制喷头与衬底进行相对移动的步骤中：控制所述喷头沿所述平行方向与所述衬底进行相对移动。
其中，在当喷头移动到衬底的表面的预定区域时，控制喷头上的至少一喷嘴喷出墨水的步骤中：控制第一速度分量和第二速度分量的大小相同，以使得喷嘴喷出的墨水在平行方向上与衬底保持相对静止。
其中，喷嘴包括喷嘴本体以及和喷嘴本体相连接的弯折部，墨水经喷嘴本体从弯折部输出，喷嘴本体垂直于衬底的表面，弯折部与喷嘴本体的夹角大于0度且小于180度，弯折部相对于喷嘴本体的弯折方向与移动单元与衬底的相对移动方向相反。
其中，喷嘴弯折部与喷嘴本体的夹角为90度。
本发明的有益效果是：区别于现有技术的情况，本发明一种制造有机发光显示器的设备以及制造方法，通过控制喷嘴的喷出速度在衬底的表面的平行方向上的第一速度分量与喷头和衬底的相对移动速度在平行方向上的第二速度分量互为反向，从而使墨水相对准确滴落在指定的区域，有效改善喷墨打印偏差的问题。

【具体实施方式】
为更进一步阐述本发明所采取的技术手段及其效果，以下结合本发明的实施例及其附图进行详细描述。
参照图1，图1是本发明一种有机发光显示器的制造设备第一实施例的结构示意图，在本实施例中，包括：喷头1，用于放置在衬底2之上并包括至少一喷嘴3，喷嘴3用于向衬底2的表面喷出墨水；移动单元4，用于控制喷头1与衬底2进行相对移动。
在本实施例中，移动单元4控制喷头1沿衬底2的表面的平行方向与衬底2进行相对移动。在其他实施例中，移动单元4控制喷头1沿其他角度相对于衬底2进行移动。此外，本实施例中所提到的“相对移动”是指喷头1与衬底2的相对位置发生变化，而不限定于喷头1与衬底2二者具体哪个进行运动。
喷嘴3包括喷嘴本体31以及和喷嘴本体31相连接的弯折部32，墨水经喷嘴本体31从弯折部32输出，喷嘴本体31垂直于衬底2的表面，弯折部32与喷嘴本体31的夹角大于0度且小于180度，弯折部32相对于喷嘴本体31的弯折方向与喷嘴3与衬底2的相对移动方向相反。
参照图2，图2是喷嘴3喷出墨水瞬间的运动速度分析图，在喷嘴3喷出墨水的过程中，由于喷嘴3的弯折部32相对于衬底2倾斜设置，喷嘴3对墨水的喷出速度V1在衬底2的表面的平行方向上和垂直方向分解为速度分量V11和V12，而此时喷头1沿衬底2的表面的平行方向与衬底2进行相对移动，因此喷头1和衬底2的相对移动速度V2在上述平行方向上的速度分量即为V2。进一步，由于弯折部32的弯折方向与喷嘴3与衬底2的相对移动方向相反，因此速度分量V11和速度分量V2互为反向。进而，能够至少部分抵消由于喷头1与衬底2相对运动过程所导致的墨水与衬底2之间的相对运动，进而从而使墨水相对准确滴落在指定的区域，有效改善喷墨打印偏差的问题。
同样，在喷头1沿其他角度相对于衬底2进行移动，同样只需要设置喷嘴3对墨水的喷出速度在上述平行方向速度分量与喷头1和衬底2的相对移动速度在上述平行方向上的速度分量互为反向均可达到上述效果。
在一优选实施例中，速度分量V11和速度分量V2的大小相同，以使得喷嘴3喷出的墨水在平行方向上与衬底2保持相对静止，从而使墨水准确滴落在指定的区域，进一步改善了喷墨打印偏差的问题。
优选的，参照图3，喷嘴弯折部32与喷嘴本体31的夹角可以为90度、120度、135度以及150度。在夹角为90度时，喷嘴的喷出速度V1在垂直于衬底2的方向上没有速度分量，而随着角度的依次增大，为了使喷嘴3的喷出速度V1在衬底2的表面的平行方向上的第一速度分量V11保持与喷头1和衬底2的相对移动速度V2在平行方向上的第二速度分量互为反向、大小相等，喷嘴3的喷出速度V1也在逐渐增大，喷嘴的喷出速度V1在垂直于衬底2的方向上速度分量V12逐渐增大。
在其他实施例中，喷嘴的具体结构可根据需要进行任意设置，只需保证喷嘴对墨水的喷出速度在上述平行方向速度分量与喷头和衬底的相对移动速度在上述平行方向上的速度分量互为反向即可实现本发明的目的。
参照图4，是本发明一种有机发光显示器的制造方法第一实施例的流程示意图，在本实施例中，制造方法包括如下步骤：
S10，控制喷头与衬底进行相对移动；
本实施例中所指的相对移动可以是衬底固定，喷头移动，也可以是喷头固定，衬底移动，并不做具体限定；
S20，当喷头移动到衬底的表面的预定区域时，控制喷头上的至少一喷嘴喷出墨水，其中，在喷嘴喷出墨水的过程中，喷嘴对墨水的喷出速度在衬底的表面的平行方向上具有第一速度分量，喷头和衬底的相对移动速度在平行方向上具有第二速度分量，第一速度分量和第二速度分量互为反向。
优选的，在S10控制喷头与衬底进行相对移动的步骤中：控制喷头沿平行方向与衬底进行相对移动。
优选的，在S20当喷头移动到衬底的表面的预定区域时，控制喷头上的至少一喷嘴喷出墨水的步骤中：控制第一速度分量和第二速度分量的大小相同，以使得喷嘴喷出的墨水在平行方向上与衬底保持相对静止。
其中，喷嘴包括喷嘴本体以及和喷嘴本体相连接的弯折部，墨水经喷嘴本体从弯折部输出，喷嘴本体垂直于衬底的表面，弯折部与喷嘴本体的夹角大于0度且小于180度，弯折部相对于喷嘴本体的弯折方向与移动单元与衬底的相对移动方向相反。喷嘴弯折部与喷嘴本体的夹角可以为90度、120度、135度以及150度，并且已经在本发明一种有机发光显示器的制造设备第二实施例中做了详尽地描述，在此不再赘述。
本发明一种有机发光显示器的制造方法第一实施例中，通过控制喷嘴的喷出速度在衬底的表面的平行方向上的第一速度分量与喷头和衬底的相对移动速度在平行方向上的第二速度分量互为反向、大小相等，从而使墨水准确滴落在指定的区域，有效改善喷墨打印偏差的问题。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
