Abstract:
A display device may have a plurality of pixels of a first group connected to a plurality of first gate lines and first common voltage lines and a plurality of pixels of a second group connected to a plurality of second gate lines and second common voltage lines. The display device drives the first common voltage lines and the second common voltage lines in synchronization with a first clock signal; and drives the plurality of first gate lines and the plurality of second gate lines in synchronization with a second clock signal. I-th first and second common voltage lines (i is a positive integer) are driven to one of a first common voltage and a common reference voltage, and (i+1)-th first and second common voltage lines are driven to one of a second common voltage and the common reference voltage.

Abstract:
A method for operating a memory controller capable of controlling a maximum count of a read retry operation is disclosed. The method includes programming a first real time clock (RTC) value indicating a time-of-day when a program operation is performed when the program operation for programming a data to a storage region of a non-volatile memory, obtaining information for the storage region by using the first RTC value read from the non-volatile memory and a second RTC value indicating a time-of-day when a read operation is performed, when the read operation for the data programmed to the storage region is performed, and decreasing a maximum count of a read retry operation by using the information, when the read retry operation is performed for the storage region.
Abstract:
A frame rate control method capable of enhancing picture-quality is disclosed. The frame rate control method generates red, green, and blue frame rate control signals by frame-rate-modulating red, green, and blue frame rate control patterns on the basis of lower-bit red, green, and blue data. The lower-bit red, green, and blue data are extracted from red, green, and blue data. The red, green and blue frame rate control patterns are obtained through a process of shifting basic frame rate control patterns by different sub-pixel numbers in one direction. The basic frame rate control patterns are established for a plurality of frames.
