Publication number: 20080158121Abstract: An exemplary gamma regulating system (20) for an LCD has a test-needed LCD (26), a light sensor (21), and a MCU (24). The LCD displays each gray scale image according to internal presetting standard gamma curve. The light sensor measures a luminance value of the gray scale image displayed by the test-needed LCD, and converts the luminance value to a voltage signal. The MCU compares the voltage signals representing the measured luminance values with the parameter data corresponding to the standard gamma curve, and regulates a gray voltage according the comparing result.Type: ApplicationFiled: December 29, 2007Publication date: July 3, 2008Inventors: Chang-Jun Liu, Gang-Qiang Zheng

Publication number: 20080158125Abstract: In a driving method capable of dot inversion without an increase in power consumption of an IC, measures are taken to deal with the lack of time for wiring data signals, when the screen is enlarged and the number of pixels increases, or when the frame frequency increases. In order to obtain the same effect as the case of the dot inversion, the pixels are arranged in a staggered arrangement in which the polarity inversion of the data signal is performed with the same frequency as in the column-by-column inversion. In order to deal with the lack of time for writing data signals because of large screen or other reasons, preliminary writing is performed when the scan line of the previous row prior to the scan line in which the data signal is to be written is selected.Type: ApplicationFiled: December 26, 2007Publication date: July 3, 2008Inventors: Ikuko Mori, Kikuo Ono
