Organic light emitting display

An organic light emitting display capable of displaying an image with uniform luminance regardless of deterioration of an organic light emitting diode and threshold voltage and/or mobility of a drive transistor is disclosed. The organic light emitting display senses deterioration of the organic light emitting diode and threshold voltage and/or mobility of a drive transistor and modifies the data supplied to the pixel according to the sensed parameters.

Organic light emitting display and driving method thereof

An apparatus and method for driving a liquid crystal display device are disclosed. The apparatus includes a liquid crystal panel with pixels defined by data and gate lines. A gate driver provides different gate pulses to the odd-column pixels than to the even-column pixels. The gate pulses have different voltages and/or widths. Data drivers provide data voltages having a positive or negative polarity to the data lines. A timing controller controls the gate and data drivers and supplies gate clock pulses that have different voltages and/or widths to the gate driver.

Display panel and display device

An LCD groups pixels in each row into a plurality of blocks, and calculates difference in gray between every two image data applied to a pair of adjacent odd and even pixels in each block including pixels in a row for each of first to third colors. It is determined that a block is first or second dot block depending on a sign of the gray difference when a magnitude of the gray difference between the odd pixel and the even pixel in each pair in the block for at least one color is equal to or larger than a critical value. A current block in a current row and in columns is determined to be a one-dot block when the current block is the first dot block and a previous block in a previous row and in the columns is the second dot block. When the number of the one-dot blocks is a predetermined percentage of the number of the total blocks, it is determined that a one-dot pattern is generated and one-dot inversion of the LCD is changed into another inversion. In this way, a pattern generating flicker is determined and the inversion type is changed for reducing the flicker.

The present invention discloses an apparatus and method for data-driving a liquid crystal display wherein data lines are time-divided to reduce the number of data driver integrated circuits and to improve the display quality of a picture at the same time. More specifically, the apparatus includes a first multiplexor array applying an input pixel data on a time-division basis, a digital-to-analog converter array converting the time-divided pixel data into pixel voltage signals, and a demultiplexor array performing the pixel voltage signals to the time-divided data lines.

Apparatus and method for data-driving liquid crystal display

A method and apparatus for driving a liquid crystal panel in a line-inversion system is disclosed. In the method, at least one pixel block each of which includes at least two data lines within the liquid crystal panel is set. The adjacent pixels in a gate line direction within the pixel block respond to data signals having the same polarity. The pixels within the other pixel areas except for the pixel block respond to data signals having a polarity contrary to the adjacent pixels at the left and right sides thereof. Accordingly, a current amount charged in the adjacent pixels having a large brightness difference is supplied always equally, so that the brightness difference between the adjacent pixels can be reduced to eliminate a noise pattern in the vertical direction.
