Title
(EN) TRANSPARENT LED DISPLAY SCREEN
(FR) ÉCRAN D'AFFICHAGE À DEL TRANSPARENT
(ZH) 一种透明LED显示屏
Abstract
(EN)
In order to overcome the problems in the transparent LED display screens in the prior art that forming a transparent conductive material for power supply on a transparent substrate as a power supply circuit by means of the printing process cannot make the spacing between the LED lamp beads small or improve the resolution of the transparent LED display screen; and that the transparent conductive material would also reduce the transparency of the transparent substrate to a certain extent, the present invention provides a transparent LED display screen, in which the mode of combining metal wires allowing a larger current with a bonding pad provided on a transparent substrate is used for supplying power to each LED lamp bead instead of printing the transparent conductive material on the transparent substrate, so as to further reduce the interval between the LED lamp beads and improve the resolution. In addition, the metal wire has a smaller diameter only blocks the line of sight slightly, so that high transparency can be ensured.

L'invention vise à résoudre les problèmes suivants dans des écrans d'affichage à DEL transparents de l'état de la technique : la formation d'un matériau conducteur transparent pour l'alimentation électrique, sur un substrat transparent, en tant que circuit d'alimentation électrique au moyen d'un procédé d'impression, ne permet pas d'obtenir un petit espacement entre des perles de lampe à DEL ou d'améliorer la résolution de l'écran d'affichage à DEL transparent ; et le matériau conducteur transparent réduit également la transparence du substrat transparent dans une certaine mesure. La présente invention concerne un écran d'affichage à DEL transparent, dans lequel on utilise un mode de combinaison de fils métalliques permettant un courant plus important avec un plot de connexion se situant sur un substrat transparent pour alimenter en énergie chaque perle de lampe à DEL, au lieu d'imprimer le matériau conducteur transparent sur le substrat transparent, ce qui permet de réduire davantage l'intervalle entre les perles de lampe à DEL et d'améliorer la résolution. De plus, le fil métallique, qui présente un diamètre inférieur, n'obstrue guère la ligne de vision, ce qui assure une transparence élevée.

为克服现有技术中透明LED显示屏采用通过印刷工艺在透明基板上形成供电的透明导电材料作为供电电路的方式无法使各LED灯珠间的间距做小,其透明LED显示屏的分辨率无法提高;且透明导电材料一定程度上也会降低透明基板的透明度的问题,本发明提供了一种透明LED显示屏,其采用可以通过更大电流的金属线与透明基板上设置的焊盘相结合的方式来替代印刷在透明基板上的透明导电材料来为各LED灯珠供电,使得其可以进一步缩小各LED灯珠之间的间距,提升其分辨率,同时,较小直径的金属线对视线的阻挡也比较小,能够保证极高的通透度。
