Abstract: An organic light emitting diode display panel includes a transparent substrate on which a matrix array of pixels is formed with each pixel including an organic light emitting diode (OLED). The OLEDS include light emitting regions sandwiched between pixel electrodes or anodes made of transparent conductive material and a common electrode made of a conductive material. The refractive index of the pixel electrodes is higher than the refractive index of the insulating layer on which the pixel electrodes are disposed so that light undergoes multiple reflections at the interface between the pixel electrodes and the insulating layer and also at the interface between the light emitting regions and the common electrode. The thickness of the pixel electrodes is chosen so that light that eventually exits the pixel electrodes after multiple reflections contains a relatively strong component of a chosen primary color.

Abstract: A liquid crystal display and a method of modifying gray signals are provided. 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.
