Abstract: A touch detection module, includes: a plurality of driving electrodes arranged side by side; a plurality of sensing electrodes staggered with respect to the driving electrodes; and a touch driving circuit configured to supply touch driving signals to the plurality of driving electrodes and to detect touch detection signals through the plurality of sensing electrodes to identify touch position coordinates, wherein the touch driving circuit is configured: to vary frequency modulation parameter set values in response to a change in a frequency of reference clocks, and to generate and supply a frequency of the touch driving signals by using the reference clocks and a varied frequency modulation parameter set value.

Abstract: A non-removable bridge dental prosthesis includes an artificial tooth to be inserted into a region from which a tooth has been lost, a bridge tightly fixed to the rear surfaces of the teeth on either side of the region from which the tooth was lost, and a coupling member for coupling the artificial tooth to the bridge. The coupling member is integrally installed on the rear surface of the artificial tooth, and has a catching piece and a coupling projection. A coupling hole is formed in the bridge in a shape corresponding to the coupling projection and is located at a position where the coupling projection of the coupling member is formed. The coupling projection is inserted in the coupling hole of the bridge and simultaneously, the catching piece is caught on the top end of the bridge.

Abstract: The present invention relates to a non-removable bridge dental prosthesis that enables an artificial tooth for replacing a damaged tooth to be conveniently and safely installed without need of an artificial dental root or removal of an adjacent tooth. According to the present invention, the non-removable bridge dental prosthesis consists of: an artificial tooth to be inserted into a region from which a tooth has been lost; a bridge tightly fixed to the rear surfaces of the teeth on either side of the region from which the tooth was lost, and having the artificial tooth inserted and fixed to the front thereof; and a coupling member for coupling the artificial tooth to the bridge.
