A receiving system and data processing method therein are disclosed, by which mobile service data is received and processed. The receiving system comprises a tuner, a filter, an IQ mismatch processor, a gain controller and a demodulator. The tuner tunes radio frequency (RF) signals of a specific channel which includes mobile service data and main service data, converts the tuned RF signals into zero IF signals and outputs the converted zero IF signals. The filter performs low pass filtering for the zero IF signals output from the tuner. The IQ mismatch processor estimates and compensates IQ mismatch generated in the zero IF signals filtered by the filter. The gain controller controls gain of the zero IF signals by estimating a gain error of the zero IF signals output from the IQ mismatch processor. The demodulator performs carrier recovery and timing recovery by receiving the zero IF signals output from the gain controller.

A method for manufacturing PDPs minimizes exposure level variances in images formed by a laser head exposer. The exposer includes an exposing region and an adjustment region on at least one side thereof. The exposer used to scan a material layer in a first direction has a first adjustment region, the exposing region and a second adjustment region, arranged along a second direction, perpendicular to the first direction. The method of using the exposer includes directly exposing the material layer along the first direction, shifting the exposer in the second direction, and repeating directly exposing the material layer in a direction parallel to the first direction, wherein a portion of the material layer exposed by one of the first and second adjustment regions during a previous directly exposing is exposed by the other of the first and second adjusting region during a subsequent directly exposing.

A structure of a TFT substrate for a high resolution digital x-ray detector, in which two TFT substrates are arranged to be a double substrate by overlapping each other such that an upper plate is moved ½ pixel distance with respect to a lower plate in a direction along one axis. Thus, a difference in movement between the upper and lower plates is a ½ pixel distance. Also, two virtual pixels are obtained from one pixel. Three TFT substrates are arranged to be a triple substrate by overlapping one another such that a middle plate is moved a ½ pixel distance with respect to a lower plate in a direction along an X axis and an uppermost plate is arranged by being moved a ½ pixel distance with respect to the lower plate in a direction along a Y axis. Thus, resolution is increased as data of one pixel is divided into four data to be analyzed and an measured value of a pixel of each overlapping substrate is compared.
