An apparatus and method for detecting radiation, which can improve the resolution of a radiation image and contribute to the simplification of the manufacture of the apparatus, are provided. The apparatus includes an upper electrode layer transmitting radiation; a first photoconductive layer becoming photoconductive upon exposure to the radiation and thus generating charges therein; a charge trapping layer trapping therein the charges generated in the first photoconductive layer and serving as a floating electrode; a second photoconductive layer becoming photoconductive upon exposure to rear light for reading out a radiation image; a lower transparent electrode layer charged with the charges trapped in the charge trapping layer; a rear light emission unit applying the rear light to the second photoconductive layer via the lower transparent electrode layer in units of pixels; and a data processing unit reading out a signal corresponding to the charges trapped in the charge trapping layer from the lower transparent electrode layer and generating a radiation image based on the read-out signal.

Apparatus and method for detecting radiation

An apparatus and method for detecting radiation are provided. The apparatus includes an upper electrode layer transmitting radiation; a first insulating layer blocking charges from the upper electrode layer; a photoconductive layer becoming photoconductive upon exposure to the radiation; a second insulating layer protecting the photoconductive layer from a plasma discharge; a lower substrate facing the second insulating layer; a plurality of barrier ribs defining a cell structure between the second insulating layer and the lower substrate; a gas layer included in an inner chamber inside the cell structure and generating a plasma discharge; a bottom electrode formed on the lower substrate; a first radio frequency (RF) electrode formed over the bottom electrode and connected to a ground source; a second RF electrode to which RF power for generating plasma is applied; and a third insulating layer surrounding the first and second RF electrodes and thus insulating the first and second RF electrodes from the gas layer and the bottom electrode.
