Abstract
(EN)
A driving method and driving circuit for a display panel. The driving method comprises the steps: divide a display panel into multiple charging areas in advance according to the distances from a data driving chip, determine a unique digital code for each charging area, and store corresponding information of the charging areas and the digital codes in a timing control chip in advance (S10); detect a charging area where a pixel to be charged is located, and output the corresponding digital code by the timing control chip according to the charging area (S11); a gamma chip receives the digital code, and generates a gamma voltage corresponding to the digital code according to an input operation voltage to drive charging operation of the charging area corresponding to the digital code (S12).

L'invention concerne un procédé de commande et un circuit de commande pour panneau d'affichage. Le procédé de commande selon l'invention consiste : à diviser à l'avance un panneau d'affichage en zones de charge multiples, en fonction des distances jusqu'à une puce de commande de données, à déterminer un code numérique unique pour chaque zone de charge, et à stocker à l'avance des informations correspondantes des zones de charge et des codes numériques dans une puce de commande de synchronisation (S10) ; à détecter une zone de charge dans laquelle se trouve un pixel à charger, et à émettre en sortie le code numérique correspondant par la puce de commande de synchronisation, en fonction de la zone de charge (S11) ; à recevoir, par une puce gamma, le code numérique et à générer une tension gamma correspondant au code numérique, en fonction d'une tension d'opération d'entrée pour commander l'opération de charge de la zone de charge correspondant au code numérique (S12).
