Description

Reinforced structure for touch panel glass

The invention relates to a reinforcing structure for a touch panel glass, in particular to a reinforcing layer formed on one side of a glass substrate and a peripheral side thereof, thereby achieving the effect of strengthening the glass, thereby making the surface of the glass substrate bright, Smooth and flatness.

In recent years, touch panels have become more and more popular, and in the design of the touch panel, the surface is often designed with a transparent glass plate as a protective glass to reduce the chance of damage due to touch or pressing.

In addition, the touch panel further includes another transparent glass plate with touch sensing function. Therefore, in the protection of glass, a number of manufacturers have gradually developed technologies for strengthening transparent glass sheets.

In the process of a transparent glass plate, a large-sized transparent glass plate is usually dispensed and cut to form a plurality of small-sized transparent glass plates to meet the size requirements of the actual product of the touch panel. At present, in the direct cutting molding technology, there are roughly the methods of Wheel Scribing and Breaking, Laser Scribing and Breaking, etching lobes and sandblasting lobes.

However, the small-sized transparent glass plate subjected to the cutting process may have defects such as micro-cracks or chipping at the edge of the cut, and these defects will reduce the strength of the transparent glass plate; therefore, when the transparent glass plate is assembled to the touch panel At the same time, since the edge of the transparent glass plate is not reinforced, the touch panel is subjected to impact or falling, and the transparent glass plate is easily damaged (such as cracking), so this problem is a place that the industry is actively trying to overcome.

Accordingly, in order to effectively solve the above problems, the main object of the present invention is to provide a reinforced structure for a touch panel glass having a tempered glass strength effect.

Another object of the present invention is to provide a reinforced structure for a touch panel glass having a flatness, brightness, and smoothness.

In order to achieve the above object, the present invention provides a reinforced structure for a touch panel glass, comprising at least one glass substrate, at least one protective film, and a reinforcing layer, wherein the glass substrate is provided with a first side and a second a side, the first side is opposite to the second side, and is adhered to an adhesive surface of the opposite protective film, and the strengthening layer is formed on the circumferential side and the second side of the glass substrate; It is formed on a glass substrate to enhance the strength of the glass, thereby more effectively achieving the effect of better flatness, brightness and smoothness of the second side surface.
