Title (EN) LIQUID CRYSTAL DRIVING METHOD AND LIQUID CRYSTAL DRIVER
(FR) PROCEDE D'ATTAQUE DE CRISTAUX LIQUIDES ET ATTAQUEUR DE CRISTAUX LIQUIDES
Abstract:
(EN) A liquid crystal driver with which the influence of the fluctuation of an r.m.s. value voltage is suppressed and the flicker is eliminated from a screen. A driving waveform in a period during which the gradation of a liquid crystal display is determined is composed of a front side driving waveform which has an edge on the front side or a rear side driving waveform which has an edge on the rear side and the front side driving waveform and the rear side waveform are switched alternately every (n) horizontal scanning signals (wherein (n) denotes a positive integer).
(FR) L'invention concerne un attaqueur de cristaux liquides qui permet de supprimer l'effet des variation de tension à valeur quadratique moyenne et d'éliminer le scintillement d'un écran. Une forme d'onde d'attaque pendant une période où la gradation de l'afficheur à cristaux liquides est déterminée, se compose d'une forme d'onde d'attaque frontale dont le flanc se trouve à l'avant ou d'une forme d'onde d'attaque arrière dont le flanc se trouve à l'arrière, les deux formes d'onde étant soumises, en alternance, à une commutation tous les (n) signaux de balayage horizontal ((n) étant un entier positif).
