Example Embodiment

[0023] Hereinafter, the present invention will be further described in detail through specific embodiments in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, a capacitive touch screen includes an upper glass substrate 1, a lower glass substrate 2, a frame glue 3, and a colorless transparent glue 4. The upper glass substrate 1 and the lower glass substrate 2 are bonded by the frame glue 3. The color transparent colloid 4 is filled between the upper glass substrate 1 and the lower glass substrate 2. The upper glass substrate 1 and the lower glass substrate 2 are both indium tin oxide (ITO) glass. The colorless transparent colloid 4 replaces the spacer material and air layer in the existing capacitive touch screen, which can effectively avoid the scattering of the air layer, increase light transmittance, increase contrast, and increase color saturation; Because the capacitive touch screen does not have an air layer, it can also avoid the Newton ring p...

Abstract

The invention discloses a capacitive touch screen and a manufacturing method; the capacitive touch screen comprises an upper glass substrate, a lower glass substrate and a sealant; the upper glass substrate and the lower glass substrate are bonded through the sealant; and transparent colorless gel is filled between the upper glass substrate and the lower glass substrate. The manufacturing method of the capacitive touch screen comprises the following steps: the upper glass substrate and the lower glass substrate are bonded together through the sealant to form a touch screen box; the glue is poured into the touch screen box; and the glue is solidified as the transparent colorless gel. The manufacturing method is simple in process. As no air layer exists, the capacitive touch screen can effectively prevent the scattering of the air layer to increase the light transmittance, the contrast and the color saturation. The capacitive touch screen can well improve the display effect.

Description

technical field [0001] The invention relates to a capacitive touch screen, and also relates to a manufacturing method of the capacitive touch screen. Background technique [0002] The touch screen is a simple, convenient and natural human-computer interaction device, which has been widely used in various places. There are many types of touch screens, which are mainly divided into resistive type, capacitive type, infrared type and surface acoustic wave type according to the principle. The capacitive touch screen uses the induced current generated by the capacitance change generated by the electrostatic combination between the electrode on the glass substrate and the human body to detect the coordinates of its touched position. The induction principle uses a voltage to act on the four corners of the screen sensing area and forms a fixed electric field. When the finger touches the screen, the electric field can cause a current. With the help of the controller, the contact can ...
