Abstract: An image displaying apparatus with local dimming control with 2-line addressing is disclosed. The apparatus includes a display panel, a light-emitting diode (LED) backlight divided into a plurality of zones, and a control unit. The control unit is configured to couple a dimming data to the LED backlight. The zones of the LED backlight are driven by row enable signals and column driving signals based on the dimming data. Each individual column driving signal transmits a common brightness data, a first residual brightness data, and a second residual brightness data. A first row enable signal has a first enable pulse in a frame period, and a second row enable signal has a second enable pulse in the frame period. The first and second enable pulses are at least partially overlapped for reducing a pulse current of the LED backlight for enhancing a lifetime of the LED backlight.

Abstract: Disclosed is a system and method of an adaptive driving compensation for enhancing display uniformity. Multiple input data patterns of the display panel are compared with image data by an image analyzing means or a user and thereby generate display control commands if non-uniformity in the display of image is detected by the image analyzing means or the user. A difference between pixel data associated with a current line and a preceding line is compared with a predefined threshold. A look up table (LUT) is scanned to add a compensation value on the pixel data the current line based upon the display control commands if the difference between the pixel data of the current line and the preceding line is greater than the predefined threshold or otherwise retain the original value of the said pixel data. The input data patterns with compensated pixel data or original pixel data is displayed.

Abstract: Disclosed is a system and method for enhancing display uniformity at display boundaries. A memory stores multiple input data patterns comprising pixel data to be displayed for multiple display time intervals. A comparator receives input data patterns for a preceding time interval. The comparator compares the difference between a pixel data associated with a pixel of a current line and a preceding line with a predefined threshold. A display controller determines a rescan pattern corresponding to a blanking time interval between the preceding display time interval and a current display time interval by driving the pixel data using a look-up table. The display panel displays the input data patterns corresponding to current display time interval after the blanking time interval having the rescan pattern such that coherency amongst display characteristics of the current display time interval and the preceding display time interval is achieved.

Abstract: Disclosed is a thin film transistor (TFT) liquid crystal display (LCD) panel. The TFT LCD panel may comprise a matrix of data bus lines and scan bus lines arranging sub-pixels. The TFT LCD may comprise gate drivers, configured to sequentially activate TFTs of sub-pixels belonging to the scan bus lines. The TFT LCD panel may comprise source drivers, configured to charge sub-pixels of the scan bus lines to render an image on the TFT LCD panel. The TFT LCD may further comprise an amplitude variation unit to compare an amplitude change on a data bus line driven by a source driver based on the image data of current scan bus line and previous scan bus line corresponding to the data bus line. The amplitude variation unit may modify the amplitude on the data bus line by a predefined value if the amplitude change is greater than a predefined threshold value.
