A gray signal modifier of the liquid crystal display includes a frame memory storing current gray signals and outputting previous gray signals stored therein, a case selector classifying pairs of the current gray signals and the previous gray signals into at least two groups based on characteristics of the difference between the current gray signals and the previous gray signals from the frame memory and generating corresponding signals, a lookup table outputting variables corresponding to MSBs of the current gray signals and the MSBs of the previous gray signals from the frame memory, and a calculator calculating the variables from the lookup table, LSBs of the current gray signals and the LSBs of the previous gray signals from the frame memory in a manner determined by the signals from the case selector and generating the modified gray signals. The modified gray signals for the pairs where the LSBs of the current gray signals and the LSBs of the previous gray signals are zero are predetermined, and the variables are determined in accordance with the predetermined modified gray signals. Accordingly, the modification of the current gray signal remarkably decreases modification errors and discontinuity. Also, image quality is increased by modifying the gray signal depending on the characteristics of the difference between the previous gray signal and the current gray signal.

摘要： A method of driving an organic light emitting display device includes generating a luminance map for a plurality of pixels by applying the same driving voltage to driving transistors formed in the plurality of pixels of a panel and by capturing luminances of the pixels, generating a threshold voltage map by calculating threshold voltage correction values that compensate for threshold voltages of the driving transistors associated with the luminances of the pixels. A lookup table is generated by sampling the threshold voltage correction values stored in the threshold voltage map. Threshold voltage correction values are restored by interpolating the sampled threshold voltage correction values, and correcting a driving voltage by adding the restored threshold voltage correction values to input gray level data and by providing the added value to the panel.

摘要： An organic light emitting device (OLED) is presented that includes: signal lines formed on a substrate; thin film transistors formed on the substrate and electrically connected to the signal lines; a first passivation layer having a concavo-convex surface; a first electrode formed on the first passivation layer; a partition formed on the first electrode and having an opening extending to the first electrode; a light emitting member formed in the opening and covered by a second electrode. The refractive indices of the light emitting member and the first passivation layer are different, and the refractive indices of the first passivation layer and the first electrode are different. The concavo-convex surface increases the luminescent surface area without decreasing the opening size, thereby enhancing the luminous power per unit pixel electrode. Forming an interface of materials whose refractive indices differ by at last 0.2 within the OLED increases light extraction efficiency.
