The present invention relates to a new mineral matter particle hydrophobization agent and to its various uses for the surface treatment of mineral matter particles. The first package and the second package are each of a single primary brand. The resilient contact element is disposed on the substrate and has at least a portion thereof which is capable of moving to a first position, which is defined by the stop structure, in which the resilient contact element is in mechanical and electrical contact with another contact element. As a result, the swings of the voltages of data lines coupled the corresponding channel are reduced, and further power consumption in the source driver could be reduced as compared with the related art.
