Description

一种镂空LED屏装置及其实现方法 技术领域
本发明涉及一种大屏显示装置及其实现方法，尤其涉及的是一种方便展示的广告或橱窗用LED显示屏装置及其实现方法的改进。
背景技术
现有技术中，LED屏显示装置已经大量应用到广告或橱窗等显示装饰位置上，在很久以前的橱窗显示中，通常是采用彩灯装饰，可以预先形成固定的造型，利用不同颜色的LED或灯珠，进行霓虹灯闪烁，形成突出的视觉效果。
此后，随着液晶显示屏的普及，在广告及橱窗展示中，可以使用显示屏进行音视频播放，虽然播放效果较好，但由于屏幕的价格较贵，考虑成本显示屏幕的尺寸一般都受到限制，并不能任意的使用较大的屏幕尺寸。此外，液晶显示屏的散热和阻挡视线，也使得其应用受到限制。
随着LED显示技术的发展，目前大屏幕广告屏和橱窗内的装饰显示已经开始采用LED显示技术，但现有的LED显示屏通常也未考虑通透性的要求，通常所形成的产品对视线的阻挡并不比以前的彩灯装饰好到哪里去。
现有技术中也存在有试图将LED灯行之间进行镂空的结构设置，但由于其LED芯片表面通常涂有用于防水防腐的三防漆，并不能有效抵抗户外的日晒雨淋，尤其是面临移动拆装频繁的舞台应用，现有技术的LED镂空设置结构很容易损坏，因而在市场上很难推广。另外，现有的镂空LED显示屏，为了加强LED显示屏的平整度，防止其起翘，在LED显示屏的两侧通常采用的是塑料板和/或玻璃板的夹持设置，导致产品结构过于复杂，不容易装配，且其透光效果很差，在实际产品应用中很难得到推广和应用。
因此，现有技术还有待于改进和发展。

具体实施方式
以下对本发明的较佳实施例加以详细说明。
本发明所述镂空LED屏装置及其实现方法的较佳实施例中，如图1和图6所示的，其设置包括一基板110，该基板110的大小可以根据实际的需要而设置，在本发明较佳实施例中，如图1所示是子板100的基板，通过多块该子板100进行拼合后，可以形成如图6所示的单元板200。单元板200的尺寸可以为1米×0.5米，而子板100的尺寸可以为0.5米×0.125米或者0.5米×0.0625米，从而可以采用在所述单元板200的每侧各横向设置4块子板100进行拼接形成单元板。本发明所述子板的设置长度一般为50-60厘米，宽度4-5厘米，并在该子板上设置LED芯片行8-12行，以便在实现足够的图像分辨率的同时保证足够的通透性，从而在通电显示图像之前，能够保证整个显示屏的通透性，看起来接近透明，而通电后图像可以突然出现，并实现足够的图像分辨率。
当然，也可以考虑竖向设置所述子板进行拼接所述单元板。但由于在所述子 板100的一侧端部(通常设置在一侧端部)设置有用于驱动LED芯片发光的驱动电路，因此，在子板100的该侧通常设置为非镂空部分120，如图1和图3及图6所示。在本发明较佳实施例中，所述单元板200上，所有子板100的非镂空部分120可以排列到一侧去，从而形成单元板的一个不够透明的区域121(即使设置所述基板采用透明材料)，如图6和图8所示。
本发明所述镂空LED屏装置如图1和图2所示，每个子板100上设置有多行LED发光芯片行111，其上按照行密布LED芯片101，如图2和图4所示，可以进行相应发光，通过驱动电路的控制可以通过各行LED芯片一起显示相应图像。在相邻的所述LED发光芯片行之间，设置采用了镂空的条形槽孔112，如图1和图3所示，除了所述非镂空部分120以外，所有的LED芯片行之间都设置为镂空的条形槽孔112，该条形槽孔112尽可能宽的形成镂空。常见的方案中，所述LED芯片行的宽度受其上所用芯片的限制，可以采用尽可能窄的条形，通常其宽度尺寸在3.5毫米左右，而所述条形槽孔的宽度在3.4毫米左右。因此，本发明所述LED芯片行的宽度可以设置与所述条形槽孔的宽度大致相同，并且所述条形孔槽尽可能的扩大宽度，以增加通透性。
本发明所述LED屏装置中，通过采用镂空的条形槽孔结构，对整个屏产品可以形成不仅对视线的通透性，而且可以形成通风效果，从而更适合于在户外的大屏幕显示装置，可以形成抗风结构降低受风的影响，从而可以实现更大尺寸的显示屏装置。
在预先进行设计的情况下，可以形成更宽的条形槽孔方案，然而，由于图像的清晰度依赖于像素点的分布密度，即所述LED芯片排列的密度(一方面在每一LED芯片行上的芯片分布密度，另一方面在纵向上，LED芯片行与行之间条形槽孔的宽度决定了纵向上的分布密度)，因此，需要考虑在通透性即所述条形槽孔越宽越好与图像精美度即条形槽孔越窄越好之间找到平衡。
在本发明另外的技术方案实施例中，可以采用所述LED芯片为侧发光的LED，这样在子板基板上设置LED芯片行时可以利用其侧发光的特点，将芯片装配到每一LED芯片行朝向所述条形槽孔的侧壁内(通过芯片侧边发光形成图像显示)，这样可以降低LED芯片行的在整个显示屏平面上的宽度，可以降至1.2毫米左右，如此，可以形成所述条形槽孔112的宽度更宽，在6.7毫米左右， 大于所述LED芯片行的宽度，形成更为通透的显示屏结构。
本发明上述LED显示屏装置能够在贴装到橱窗或广告牌上时，形成“隐形”屏幕，尤其是针对舞台布景的隐藏显示装置，在本发明子板拼装形成的显示屏通电前，整个屏是看起来透明的，稍远就基本不影响视线，感觉很通透。而一旦通电发光开始显示图像，就会发现显示屏有图像，具有显示效果，会形成一种从无到有的冲击效果。在稍远位置，例如3-5米以上，本发明的镂空LED显示屏装置可以显示精细的图像画面，完全媲美液晶显示大屏。
为保证本发明LED屏装置适应户外的防晒防水等要求，本发明所述镂空LED屏装置较佳实施例中还将所述LED芯片行设置采用透明的防腐蚀封胶进行涂覆，较佳的是，所述防腐蚀封胶采用环氧树脂制成。
为进一步支撑所述子板100，在所述LED芯片行的后侧设置有同样镂空结构的透明底壳，该透明底壳可以设置成与所述子板100一样的尺寸大小，也可以设置成以单元板200的尺寸为参照大小，并在单元板上进行支撑设置。所述透明底壳可以采用PC制成。
在本发明较佳实施例中，如图5a、图5b和图5c所示，透明底壳113设置为与所述子板100大小一致。该种设置方式能够方便支撑所述LED芯片的显示，由于LED芯片行显示的最终是图像，因此，LED芯片行需要保持其整体的平整度，以防止图像显示时的宏观变形。由于本发明所述LED屏装置增加了该透明底壳作为支撑结构，保证所述LED芯片行的平整不变形，从而实现图像的更为清晰和正常。
由于本发明所述LED屏装置在子板100上须要设置其非镂空部分120用来装配驱动模块(所述驱动模块220设置在非镂空部分120的后侧，参见图9所示)，因此，在实际的使用过程中，该非镂空部分120相比于镂空部分的通透性，会出现在整个显示屏上有一条颜色特别的区域，尤其是在单元板200的竖向中间位置，会形成一个竖向带区域210，如图6所示，因此为降低其对整个显示屏的影响，本发明所述LED屏装置中，对该非镂空部分采用了较镂空部分的LED芯片行颜色更深更暗的颜色，可以保证整个显示屏在非显示图像状态时的整体观感的一致性，在非显示图像状态时，整个显示屏具有一定的通透性，整体上看起来是透明的，尤其是在舞台背景上，光线较暗的环境下。
本发明所述LED屏装置通常采用如图6至图10a、图10b所示的单元板200再去拼接更大面积的显示屏。在每一单元板200中，设置包括框架支架201，如图10a和图10b所示，在所述框架支架201上设置若干块子板100进行拼接。根据所述单元板200的尺寸不同，而由不同数量的所述子板100进行拼接，并且其拼接的结构方式不限于图示示例，可以横向或纵向拼接。
本发明所述单元板200采用1米×0.5米尺寸设置的方式形成单元，方便了对更大屏的拼装，因为其体积和重量刚好方便一个人在高空操作。本发明所述单元板200在舞台显示屏的拼接使用中具有特别的技术优势，原因在于，舞台拼接需要操作和调整的迅速，而且是短期使用，需要拆拆装装，就很容易因为磕碰而损坏显示屏。本发明用于拼接所述单元板的每一子板上，其LED芯片行都通过抗碰撞防潮防晒的透明封胶进行处理，形成的产品特别防撞，尤其方便了在户外的舞台显示屏搭建。由于采用条形槽孔使整个显示屏的通透性很高，本发明所搭建的舞台显示屏，在通电工作之前，可以隐藏于舞台的正常背景之前，从舞台下是很难看到整个显示屏的，而一旦对显示屏进行通电开始工作，则整个显示屏如同从空气中出现一样，因此具有特别突出的冲击性效果。而采用侧面发光的LED芯片时，所述条形槽孔的宽度更大，因此整个显示屏的通透性效果更佳。
在本发明方法的较佳实施例中，如图11所示，其包括以下步骤：在基板上加工时排列所述LED发光芯片形成多行LED芯片行，其间隔按照预先设定的间隔，以及考虑LED芯片的功率和尺寸而确定；其次，在所述LED芯片所在的基板上涂覆透明的防腐蚀封胶，这样可以提高工作效率，可以实现设备的自动加工；当涂覆的防腐蚀封胶凝固后，可以将LED芯片行之间的空隙进行镂空加工，形成条形槽孔。该条形槽孔的加工可以通过在所述LED芯片行之间的空隙位置进行切割完成。
本发明所述LED屏装置的实现方法另一较佳实施例中，如图12所示，所述LED芯片还可以采用侧发光的LED芯片，其加工实现的步骤是：先将所述基板根据预先设定的LED芯片行位置，将其之间的空隙进行镂空切割加工，形成条形槽孔；其次，在这些条形槽孔的一侧侧壁上排列所述LED发光芯片，形成多行的LED芯片行，较好的是，在这些条形槽孔的同一侧侧壁上进行设置所述LED发光芯片，这样可以保证所有LED芯片行的间隔均匀；再在所述LED芯片所在 的基板上涂覆透明的防腐蚀封胶，例如环氧树脂材料。这样形成的所述条形槽孔宽度就会远远大于所述LED芯片行的宽度，因此，在本发明所述LED屏装置的实际使用中，能够实现更高的通透性，产品的显示效果与通电显示前的通透性对比更加明显。
为增强本发明所述LED屏装置的整屏平整性，还可以在所述LED芯片行的后侧设置有同样镂空结构的透明底壳，用来贴合支撑所述镂空LED屏装置。所述透明底壳的结构同样存在条形槽孔形成的通透性结构，但所述透明底壳的条形槽孔结构可以设置成与所述LED芯片行方向垂直，而不一定采用平行的结构方案，此种实现方案虽然降低了通透性，但其形成产品整体刚性加强，特别可以用来在对通透性要求不那么高的场合。
本发明所述LED屏装置的实现方法中，针对使用侧发光的LED芯片的实现，还可以单独形成各LED芯片行的显示条，然后通过黏贴到透明底壳等框架上的方式进行加工实现。
为增强所述镂空LED屏装置的整体支撑性，在所述条形槽孔112上还可以设置至少一条竖向加强筋114，如图1所示，可以用来保证所述子板及单元板的整体抗扭曲强度，以保证显示图像的平整度。
本发明所述镂空LED屏装置及实现方法实现了一种适应户外广告的新型显示屏装置，其可以通过设置条形槽孔以及对LED芯片行的防腐蚀封胶，既可以实现通透性高的显示屏装置，在通电前后形成强烈反差，又可以实现减少风阻，方便户外高空的安装，和适应户外的风吹雨淋，而且通过模块化结构设置，可以针对舞台的临时搭建需要形成快拆快装的显示屏装置，方便重复拆装使用。
应当理解的是，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本发明所附权利要求的保护范围。
