Abstract:
A liquid crystal display (LCD) device includes a display including a plurality of pixels, a voltage compensation controller configured to control the plurality of pixels and determine whether to compensate a predetermined grayscale voltage to be applied to the plurality of pixels, and a voltage generator configured to provide the predetermined grayscale voltage to the plurality of pixels in response to the voltage compensation controller determining not to compensate the predetermined grayscale voltage, and to compensate the predetermined grayscale voltage and provide the compensated predetermined grayscale voltage to the plurality of pixels in response to the voltage compensation controller determining to compensate the predetermined grayscale voltage.
Abstract:
A boot secure device that performs a secure booting operation of a semiconductor system includes an external memory interface that provides an interface with an external memory, a first internal memory that stores a boot image stored in the external memory, a second internal memory that stores a hash of a first public key, a secure accelerator that verifies the boot image using the hash of the first public key, and a secure boot sequencer that includes a plurality of states and a plurality of operation and that controls the external memory interface, the first internal memory, the second internal memory, and the secure accelerator using at least one of the plurality of operations when a state transition occurs between two of the plurality of states.

Abstract:
A demodulator for a near field communication (NFC) includes a first rectifier, a shifting rectifier, a field monitor and an edge detector. The first rectifier receives an antenna voltage through a first power terminal and a second power terminal, rectifies the antenna voltage and provides a first rectified signal to a first node. The shifting rectifier is enabled in response to an enable signal, receives the antenna voltage through the first power terminal and the second power terminal, increases a direct current (DC) level of the antenna voltage, rectifies the increased DC-level antenna voltage and provides a shifted rectified signal to the first node. The field monitor receives the antenna voltage through the first power terminal and the second power terminal, monitors a magnitude of the antenna voltage and generates the enable signal which is activated when the magnitude is smaller than a reference value.
Abstract:
A method for generating an image combined with audio, and image display and audio output includes displaying an image, when a first image object within the image is selected, outputting a first audio object corresponding to the first image object and, when a second image object within the image is selected, outputting a second audio object corresponding to the second image object.
