Capacitance touch screen and manufacturing process thereof

Abstract

The invention provides a capacitive touch screen and a manufacture method thereof. The capacitive touch screen comprises a transparent upper base plate and a transparent lower base plate provided with an electrode layer; the transparent upper base plate and the transparent lower base plate are jointed together through solidifiable gluewater; rim glue is also arranged on the periphery of an abutted surface between the upper base plate and the lower base plate; and at least an opened opening is arranged on the rim glue. The manufacture method comprises the steps as follows: a strip of rim glue provided with at least one opened opening is formed on the periphery of the abutted surface of any one base plate; glue is dripped to the abutted surface of the base plate through an adhesive-dripping device; then another base plate is jointed to the base plate which is dripped with glue; the dripped glue is solidified after spreading and fully covering the abutted surface of the base plate; and overflowing glue at the opening is cleared. The capacitive touch screen and the manufacture method thereof can lead air bubbles to be removed from the opening gradually during the process of jointing the upper base plate and the lower base plate, the overflowing glue position is changeless and is convenient to be cleared, and the capacitive touch screen and the manufacture method have the advantages of increasing product quality, process stability in batch production, etc.

Description

technical field [0001] The invention relates to a structural improvement of a touch screen, in particular to a capacitive touch screen, and also relates to a method for manufacturing the capacitive touch screen. Background technique [0002] The touch screen can be used as an interface tool for operating electronic devices through the display screen, allowing users to input information directly on the surface of the display device with a touch screen by touching or handwriting, which is more friendly and convenient than input devices such as mice and keyboards. Therefore, it is more and more widely used in various portable devices, such as mobile phones, PDAs and so on. For example, a user may input desired information on a display device that is displaying an image and is combined with a touch screen. [0003] According to the type of contact object used (such as fingers, pens, etc.) and the way of confirming the contact (the position where the contact object operates the ...
