Abstract:
Disclosed is a method of converting a communication channel in a mobile communication terminal. According to the invention, the specific absorption rate (SAR) value information according to each of the communication channels are stored and managed in the mobile communication terminal, so that a communication channel having a relatively low SAR can be assigned from a new base station when there occurs a handoff or a call processing for a call incoming/originating is performed. Like this, the newly assigned communication channel is converted into a communication channel of the terminal, thereby minimizing an effect of the electromagnetic wave influencing on the user of the terminal during the communication. In addition, the SAR value information according to each of the communication channels are stored and managed in the mobile communication terminal, so that it is possible to indicate the SAR of the current communication channel of the terminal to the user.

Abstract:
Disclosed is a method of forming patterns in semiconductor devices by using photo resist patterns. These methods comprise forming photo resist patterns on a substrate. Inferior patterns are selected among the photo resist patterns. The inferior patterns are eliminated or shrunken by irradiating the selected inferior patterns with an electron beam.
Abstract:
A display panel includes n gate lines, a data line, a first pixel and a second pixel. The gate lines extend in a first direction. The data line extends in a second direction transverse to the first direction. The first pixel includes a first pixel electrode connected to one of the (n−1) gate lines to receive a data voltage through the data line. The second pixel includes a second pixel electrode and a light-blocking pattern. The second pixel electrode is connected to the (n)-th gate line to receive the data voltage through the data line. The light-blocking pattern obscures the second pixel to possibly reduce a luminance difference between the first and second pixels.
