METHOD AND APPARATUS FOR CONTROLLING LUMINANCE OF ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE |
摘要 |
A luminance controller of an OLED device and the OLED device including the luminance controller include a peaking processor for calculating a minimum gray level value by filtering low gray level data from primary RGB data and determining a compensation gain value corresponding to the minimum gray level value; a boosting processor for calculating a maximum gray level value by filtering high gray level data from the primary RGB data, calculating a gain value corresponding to the maximum gray level value, and calculating a coloring ratio coefficient using the minimum gray level value and the maximum gray level value; and a secondary RGB generator for generating secondary RGB data by applying the compensation gain value, the coloring ratio coefficient, and the gain value to the primary RGB data. |
