Abstract: A Cu-In-Zn-Sn-(Se,S)-based thin film for a solar cell and a preparation method thereof, and more particularly, to a Cu-In-Zn-Sn-(Se,S)-based thin film for a solar cell which can reduce an amount of In to be used and exhibit an excellent conversion efficiency and a preparation method thereof.

Abstract: A method and apparatus for suppressing screen flicker phenomenon resulting from differences between a scanning frequency of a camera module and a mains power frequency of the region where the mobile terminal is located are provided. The method includes acquiring, when a camera module of the mobile terminal is activated, location information of the mobile terminal, determining a power frequency mapped to the location information, and matching a scanning frequency of the camera module to the power frequency.

Abstract: An information detecting display device includes an information detecting substrate having a photo-sensor and a switching substrate facing the information detectable substrate, wherein the information detectable substrate includes a first substrate, a plurality of photo-sensors arranged in a matrix on the first substrate and which generate sensing signals, a plurality of sensor scanning lines which transmit sensor scanning signals for controlling output of the sensing signals and a plurality of sensor signal lines which transmit the sensing signals in response to the sensor scanning signals, wherein at least two of the sensor scanning lines transmit substantially the substantially same sensor scanning signals simultaneously.
