Abstract: A display module includes a thin film transistor (TFT) substrate including a glass substrate, a TFT layer provided at a front surface of the glass substrate and comprising a TFT electrode pad, and a driving circuit provided at a rear surface of the glass substrate and configured to drive the TFT layer, at least one light-emitting diode (LED) comprising at least one LED electrode pad, and a junction structure provided between the at least one LED electrode pad and the TFT electrode pad. The junction structure is formed in a metallically bonded state.

Abstract: Disclosed is an apparatus for measuring salinity of interstitial water in a soil sample, the apparatus including: an air supplier that generates a stream of high-pressure air; an air nozzle from which the high-pressure air, supplied from the air supplier, is ejected; a soil-compressing tank into which the high-pressure air, ejected from the air nozzle, is introduced and which compresses a soil sample contained therein to squeeze interstitial water from the soil sample; and a water tank which collects and stores the interstitial water drained from the soil-compressing tank and in which a salinity-measuring sensor for measuring salinity is installed to measure salinity of the interstitial water.
