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: The present invention relates to a process for preparing isobutene-cyclodiene copolymers having a number-average molecular weight of at least 100,000 and an unsaturation of 1.about.30% by mol, characterized in that polymerization is carried out without gelation by reacting 75.about.99.5% by weight of an isobutene and 0.5.about.25% by weight of a cyclodiene or a mixture of cyclodiene as reaction materials, in a polar reaction solvent of 1.about.10 times by weight with respect to the reaction materials, wherein a catalyst solution of 0.02.about.2% by weight in the polar solvent is used in the amount of 0.2.about.2 times by weight with respect to the reaction materials, at a reaction temperature of -100.degree..about.-85.degree. C., thereby obtaining a copolymer, and then removing the residual catalyst activity at a temperature of -100.degree..about.-25.degree. C.
