This disclosure relates to a technical field of a display device, and more particularly to a display device, a display and a method for assembling a display panel with a backlight module.
Most of the current display devices comprise front bezels or frames for mounting display panels and backlight modules. Such configurations usually result in that the appearances of the display devices are not stylish and beautiful.
Currently some frameless display devices are still available in the market. Such frameless display device generally uses double-sided tapes to bond and fix the display panel to the backlight module. Alternatively, the bonding and fixing of the display panel and the backlight modules are carried out via coating liquid glues on corresponding bonding portions of the display panel and the backlight module, followed by attaching and drying. The adhesion between the display panel and the backlight module provided by the liquid glues or the double-sided tapes may usually diminished after a long-term use or under a high-temperature and high-humidity condition, such that the display panel and the backlight module may be then fixed to each other very well.
