Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution:
a capacitive touch screen with high yield comprises a first protective shell 1, a second protective shell 2 is clamped at the front end of the first protective shell 1 through two groups of buckles, cavities are formed in the first protective shell 1 and the second protective shell 2, a falling-preventing layer 3 is arranged in each cavity, the front end of the falling-preventing layer 3 penetrates to the outside of each cavity, a waterproof layer 4 is arranged on the rear side of the falling-preventing layer 3, a conductive layer 5 is arranged on the rear side of the waterproof layer 4, a touch panel electrode layer 6 is arranged on the rear side of the conductive layer 5, a glass substrate 7 is arranged on the rear side of the touch panel electrode layer 6, an LCD panel 8 is arranged on the rear side of the glass substrate 7, the LCD panel 8 is electrically connected with the touch panel electrode layer 6 through wires, heat-conducting silica gel is coated on the outer wall on the rear side of the first protective shell 1, a rear heat dissipation plate is embedded at the back of the first protective shell 1, each component in each, thereby reducing the ambient temperature within the cavity.
Electric connection has four group's response electrode 11 on touch panel electrode layer 6, four group's response electrode 11 are located the cavity respectively, down, a left side, on the four side inner walls on the right side, electric connection has connecting wire 9 on touch panel electrode layer 6, through-hole 10 has been seted up to the cavity bottom, the connecting wire 9 other end runs through to the cavity outside through-hole 10, and electric connection is on external electronic equipment, thereby can guarantee touch-sensitive screen normal use, all scribble the anti-rust paint layer that is equipped with on first protecting crust 1 and the 2 outer walls of second protecting crust, avoid long-time back of using, oxidation phenomenon can appear on first protecting crust and the 2 surfaces of second protecting crust, the joint of first protecting crust 1 and second protecting crust 2 splices has the sealing strip, not only can strengthen the fixity between first protecting crust 1 and the second protecting crust 2, also further prevent that water stain can get into from the gap.
