Description

Technical Field

[0001] The utility model belongs to the technical field of capacitive touch screens, and particularly relates to a capacitive touch screen for a tablet computer. Background Technique

[0002] Capacitive touch technology is a touch technology that utilizes the capacitance change generated when a finger approaches a capacitive touch panel. There are two important capacitance parameters in capacitive touch. One is the induction capacitance between the finger and the upper sensing material, and the other is the parasitic capacitance between the sensing materials or between the sensing material and the optical panel. Parasitic capacitance will be generated between conductors, and when a finger conductor approaches a sensing conductor with different voltages, an induction capacitance change will also occur. Capacitive touch technology is relatively stable and has high reliability. By virtue of the characteristic that the human body itself is a capacitive body, the capacitance change generated when contacting the touch panel achieves the sensing touch effect.

[0003] For example, the patent with the publication number CN215814119U discloses a capacitive touch screen for a tablet computer, which relates to the technical field of capacitive screens. It includes a capacitive screen main body, a controller, an outer frame, electronic potting glue, and an explosion-proof film. The capacitive screen main body is electrically connected to the controller. The capacitive screen main body is installed in the outer frame. The electronic potting glue is filled at the joint of the upper and lower end faces of the capacitive screen main body and the outer frame. The explosion-proof film is installed on the upper end face of the capacitive screen main body. This capacitive touch screen for a tablet computer uses an outer frame for edge wrapping, and the upper and lower joint end faces of the outer frame and the capacitive screen main body are encapsulated by electronic potting glue. At the same time, an explosion-proof film is added to protect the use surface of the capacitive screen main body. It has strong impact resistance and can effectively filter the glare in external light, maximizing the avoidance of harm to the screen body from the outside, thereby prolonging the service life of the display screen and improving its display effect.
