Problems solved by technology

However, this raises another problem: when glass is used as a display window, if it is subjected to an impact exceeding a critical level, the glass may break into pieces, which is devastating to the display window and also may cause harm to the user
Another disadvantage is that it takes too long to prepare the vacuum state, and the limited space in the vacuum chamber makes it impossible to manufacture a large number of display device windows at the same time, which inevitably increases the manufacturing cost

Embodiment Construction

[0058] Now, the display device window of the present invention is described in detail in conjunction with the accompanying drawings:

[0059] The display device window of the present invention includes a synthetic resin substrate 10 and a glass 30 bonded to an upper surface or a lower surface of the synthetic resin substrate 10 by dispensing a UV (ultraviolet) adhesive 20 . Preferably, the synthetic resin substrate 10 is partially or completely cut at the edge where the glass 30 is bonded to the surface and side walls of the synthetic resin substrate 10 , where the edge is provided with the gas discharge portion 12 that facilitates gas removal. Alternatively, the gas discharge part 12 may be provided on the glass 30 instead of the synthetic resin substrate 10 . In other words, the glass 30 is partially or entirely cut at the edge where the synthetic resin substrate 10 is bonded to the surface and side walls of the glass 30 , where the edge is provided with the gas discharge po...

Abstract

The present invention provides the characteristic window for display device, and also provides the manufacturing method of window for display device and the wireless terminal unit using the manufacturing method of window for display device, wherein the manufacturing method is characterized by: coating a UV-adhesive to a glass; positioning a synthetic resin substrate on the UV-adhesive coated glass; passing the synthetic resin substrate through a roll press to gradually press from a first end region of the synthetic resin substrate to a last end region of the synthetic resin substrate and to remove gas; and irradiating UV light to cure the UV-adhesive. The present invention provides industrially applicable window for display device whereby decoration is easy on a window, and air bubbles can be easily removed during processes where the synthetic resin substrate and glass are UV-adhesive bonded through a particular method to facilitate a mass production of windows in a short period of time.

Description

technical field [0001] The invention relates to a manufacturing method of a display device window, a display device window and a wireless terminal unit including the display device window. Background technique [0002] A wireless terminal unit (hereinafter referred to as a terminal) is generally provided with a display device including, for example, liquid crystal and ELED (Edge Emitting Light Emitting Diode (ELED)), which is generally protected with a window. Conventional windows employ synthetic resin substrates made of acrylic resin, PC (polycarbonate), or PET (polyethylene terephthalate). With the current trend of terminal miniaturization and weight reduction, the thickness of the display device window is also gradually reduced. [0003] However, if the synthetic resin substrate becomes thinner, its strength decreases due to its inherent characteristics and cannot provide sufficient protection against external impact for the display device. Another disadvantage of synt...
