Description

一种高透明LED显示模块 技术领域
本实用新型涉及一种LED发光装置，尤其涉及一种高透光LED显示模块。
 背景技术
LED显示屏因其尺寸灵活，环境适应性强的特点使其在媒体领域得到广泛应用。在某些特别的场合，如玻璃幕墙、商店橱窗、舞台背景、商场、酒店、机场等环境需要LED显示模块通透性高，采光透视效果好，同时又要保持一定的像素密度。因此，市场上出现了许多条状LED显示屏，这种LED屏幕是将LED发光单元安装在一根根条状的电路板上，然后以不透明的外壳固定， 若干这样的灯条组成一个单元模块，若干单元模块再级联成显示屏。 由于不透明外壳占用较大空间， 这种单元模块的像素间距一般要做到40mm以上才有一定的透光效果，但是像素间距太大则不适用于观看距离较小的应用场合。同时， 由于这种不透明显示模块条状结构非常明显， 无论安装在室内还是室外， 都会给人一种束缚感， 并不适用于商店橱窗、商场玻璃幕墙等这样的高档应用场合，市场呼唤既具有高像素密度又具有高通透性的LED显示屏。
技术问题
本实用新型的目的是为了克服现有技术的不足，提供一种无需复杂框架结构，结构简易，制造方便，具有很高采光透视效果的高透明LED显示模块。
 技术解决方案

所述的LED发光单元还包括LED发光体安装PCB板，LED发光体安装PCB板截面与LED发光体截面相当，安装PCB板垂直固定于驱动PCB板板面上并与驱动PCB板电性连接。
所述的灯孔为通孔或盲孔。
所述的线槽深度与驱动PCB板的宽度匹配。
所述驱动PCB板上下两面设有对称的LED发光体。
所述的LED发光体安装PCB板的正反两面均安装有LED发光体。
所述的LED发光体为单色或多色发光二极管。
所述的透明玻璃板是由但不仅限于PMMA（亚克力）高分子材料制成的高透明度均质基板。
 有益效果
本实用新型利用有机玻璃美观、高透明度及易于机械加工的特点，以透明玻璃板为LED模块的基板，同时把影响透光的驱动PCB板垂直安装在透明玻璃板面上，极大地减少了驱动PCB板对光线的遮挡，提高了显示模块的透明度和像素密度。同时，通过LED发光体与驱动PCB板的有机连接，使得LED发光体安装方便，还可实现双面显示的功能，提高了显示模块的使用效率。本实用新型可直接粘贴安装在透明玻璃幕墙的内侧，发布广告信息，极大地节省了安装空间及提高了单位面积的像素密度，还可用于指示牌，用于商场、酒店、学校、医院、机场等公共场所，具有相当广阔的应用前景。

 本发明的最佳实施方式
下面结合附图和具体实施方式对本实用新型作进一步详细的说明。
图中标号统一说明如下：透明玻璃板1、灯孔101、线槽102、驱动PCB板201、安装PCB板202、LED发光体3、主驱动单元4。
一种高透明LED显示模块，包括透明玻璃板1、线性排列的LED发光单元和主驱动单元4，透明玻璃板1设有按像素间距排列的灯孔101，灯孔101为通孔或盲孔。沿横向或竖向排列灯孔开设有垂直于透明玻璃板面的线槽102，线槽102深度与驱动PCB板201的宽度匹配。LED发光单元包括驱动PCB板201、LED发光体3和LED发光体安装PCB板202，安装PCB板202垂直固定于驱动PCB板201板面上并与驱动PCB板201电性连接；LED发光体3固定于安装PCB板202板面并与安装PCB板202电性连接；驱动PCB板201平行套嵌于透明玻璃板1的线槽102内，固定有LED发光体3的安装PCB板202与灯孔101位置对应。
实施例一
如图1至3所示，透明玻璃板1为有机玻璃板，透明玻璃板1上按照所需的像素间距（如16mm)开设按像素间距排列的若干灯孔101，灯孔101为通孔。沿灯孔101横向排列方向开设垂直于透明玻璃板1板面的线槽102，线槽102设置在灯孔101的侧边缘。
如图4和图5所示，在一细长条的驱动PCB板201上垂直固定安装PCB板202，安装PCB板202的间距与设定的像素间距相同，平面方向与透明玻璃板1的平面方向平行。
如图6和图7所示，安装PCB板202的板面上安装SMD贴片LED发光体3。
如图8和图9所示，驱动PCB板201与安装PCB板202电连接并实现控制LED发光体3工作，根据LED发光体3所需的控制方式设定主驱动单元4控制电路，控制LED发光体3的明暗和颜色变化。其中驱动PCB板201嵌入安装在透明玻璃板1的线槽102内，LED发光体3刚好在灯孔101的位置上。驱动PCB板201安装小而薄的驱动元件，主驱动单元4安装体积较大的驱动元件。
实施例二
如图10所示，安装PCB板202对称安装在驱动PCB板201的上下两面，两个LED发光体3分别安装在安装PCB板202上，透明玻璃板1也相应地在每个像素位置开两个灯孔101（图中未示出），这样可以提高模块的发光亮度，有效节省驱动电路的占用空间。
实施例三
如图11所示，安装PCB板202的正反两面上分别装有LED发光体3，两个LED发光体3通过印制在驱动PCB板201和安装PCB板202的相同或不同电路控制，形成可以两面发光。由此组成的显示模块可发布相同或不同的图文信息。此时主驱动单元4和骨架安装在显示模块的侧边（如图14所示），可以让显示模块两边的观众都看到完整的图文信息。
如图12、图13所示，所有的驱动PCB板201由主驱动单元4内驱动电路控制使所有模块上的LED发光体3都能独立控制明暗和颜色变化，形成发布图文信息的LED单元模块，若干这样的LED单元模块相互级联，便形成一定尺寸的LED显示屏。各模块可以直接粘贴在玻璃幕墙的背面，向室外发布图文信息，由此，从室内向外看，具有很高的透视效果，从室外看，可以看到发布的图文信息。本实用新型可以在有限的玻璃幕墙面积上实现很高的像素密度，以像素间距16mm为例，其像素密度可达到3906点/㎡，比普通40mm像素间距的条形屏625点/㎡的像素密度有显著提高。
更进一步地，透明玻璃板1还可以做成弧形，驱动PCB板201相应地也制成弧形，以满足特殊的LED显示模块形状要求；透明玻璃板1前面还可再加置一层玻璃板，以达到前面防水的目的；透明玻璃板1可以沿驱动PCB板201的方向制成条状，以达到通风效果。
