Abstract
(EN)
An LED light board fixing device (1) for fixing an LED light board (2) on the front surface, a display device comprising the LED light board fixing device (1), and a tiled display device. Said fixing device (1) comprises a plastic main body (11) and an anti-deformation plate (12) fixed on the front surface of the plastic main body (11) for limiting deformation of the fixing device (1). By providing an anti-deformation plate on the front surface of the plastic main body for limiting the deformation of the fixing device caused by a temperature change, the present invention enables the deformation of the fixing device to be small when the temperature changes, such that after the display devices are tiled into an integral display screen, a gap between two display devices can be reduced or even eliminated at a high temperature, improving the display effect, and the compression between adjacent light boards is reduced or even eliminated at a low temperature, reducing the possibility of damage to lamp beads, prolonging the service life.
(FR)
L'invention concerne un dispositif de fixation de panneau lumineux à DEL (1) destiné à fixer un panneau lumineux à DEL (2) sur sa surface avant, un dispositif d'affichage comprenant le dispositif de fixation de panneau lumineux à DEL (1), et un dispositif d'affichage en mosaïque. Ledit dispositif de fixation (1) comprend un corps principal en plastique (11) et une plaque anti-déformation (12) fixée sur la face avant du corps principal en plastique (11) pour limiter la déformation du dispositif de fixation (1). Par disposition d'une plaque anti-déformation sur la surface avant du corps principal en plastique pour limiter la déformation du dispositif de fixation provoquée par une variation de température, la présente invention permet de réduire la déformation du dispositif de fixation quand la température varie, de telle sorte que, après que les dispositifs d'affichage ont été mis en mosaïque en un écran d'affichage intégré, un écartement entre deux dispositifs d'affichage puisse être réduit ou même éliminé à haute température, améliorant l'effet d'affichage, et la compression entre des panneaux lumineux adjacents soit réduite ou même éliminée à basse température, réduisant la possibilité d'endommagement de perles de lampe, prolongeant la durée de vie.
(ZH)
一种用于在前表面固定LED灯板(2)的LED灯板固定装置(1),以及包括LED灯板固定装置(1)的显示装置和拼接式显示器件,固定装置(1)包括塑胶主体(11)以及固定于塑胶主体(11)前表面用以限制固定装置(1)发生形变的抗形变板(12)。通过在塑胶主体前表面设置用以限制固定装置因温度变化发生形变的抗形变板,使得固定装置在温度变化时形变较小,从而拼接成整体显示屏面后,在高温时能减小甚至避免两显示装置之间出现缝隙,提升显示效果,在低温时减小甚至避免相邻灯板之间的挤压,减小灯珠损坏的可能,提升使用寿命。
