Problems solved by technology

[0002] The existing capacitive touch screen cannot shield electromagnetic waves, and it has no shielding effect. The traditional process is to directly paste a piece of shielding film or shielding glass on the back of the capacitive touch screen, which can only satisfy the inward function of the shielding film or shielding glass. Shielding effect, its shielding effectiveness is poor; and in the field of military industry or aviation, the performance requirements for shielding interference signals are very high

Abstract

The invention discloses a capacitive touch screen with shielding effectiveness. The capacitive touch screen comprises a liquid crystal screen, a shielding film layer, a connecting piece and a circuitboard. The circuit board is provided with a first shielding chip, a second shielding chip, a processor, a first RC module and a second RC module, wherein the first RC module and the second RC module are connected with the processor. The first shielding chip is provided with a plurality of first shielding pins, and the second shielding chip is provided with a plurality of second shielding pins, wherein the first RC module comprises a plurality of transversely arranged first RC components, and each first RC component comprises a first capacitor and a first resistor which are connected with eachother; the second RC module comprises a plurality of longitudinally arranged second RC assemblies, and each second RC assembly comprises a second capacitor and a second resistor which are connected with each other. The RC assembly is added to each circuit of the touch screen, external interference electromagnetic waves are filtered out through the resistance of each path, and therefore the capacitive touch screen is free of interference, and electromagnetic compatibility is met.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a capacitive touch screen with shielding effect. Background technique [0002] The existing capacitive touch screen cannot shield electromagnetic waves, and it has no shielding effect. The traditional process is to directly paste a piece of shielding film or shielding glass on the back of the capacitive touch screen, which can only satisfy the inward function of the shielding film or shielding glass. Shielding effect, its shielding effectiveness is poor; and in the field of military industry or aviation, the performance requirements for shielding interference signals are very high. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a capacitive touch screen with shielding effect, and the technical solution is as follows: [0004] The invention provides a capacitive touch screen with shielding effect, which incl...
