Title (EN) OLED PWM DIGITAL DRIVING METHOD AND CIRCUIT
(FR) PROCÉDÉ ET CIRCUIT D'EXCITATION NUMÉRIQUE À MLI D'OLED
(ZH) 一种OLED PWM数字驱动方法及电路
Abstract: front page image
(EN)An organic light-emitting diode (OLED) pulse width modulation (PWM) digital driving method and circuit, the method comprising: dividing scan lines (L1, L2,…, L1280) of each sub-field (bit0, bit1, …, bit5) in an OLED PWM architecture into a plurality of sets (A, B, C and D) (S110); simultaneously scanning the scan lines (L1, L2, …, L1280) in each set (A, B, C and D), thereby increasing a ratio of pixel lightening time in one image frame (S120).
(FR)L'invention concerne un procédé et un circuit d'excitation numérique à modulation de largeur d'impulsions (MLI) de diodes électroluminescentes organiques (OLED), le procédé comportant les étapes consistant à: diviser des lignes (L1, L2,…, L1280) de balayage de chaque sous-champ (bit0, bit1, …, bit5) dans une architecture de MLI pour OLED en une pluralité d'ensembles (A, B, C et D) (S110); balayer simultanément les lignes de balayage (L1, L2, …, L1280) dans chaque ensemble (A, B, C et D), accroissant ainsi un rapport de temps d'éclaircissement de pixels dans une trame d'image (S120).
(ZH)一种OLED PWM数字驱动方法及电路,该方法包括将OLED PWM架构中每个子场(bit0,bit1,…,bit5)的扫描线(L1,L2,…,L1280)分成多组(A,B,C,D)(S110);每组(A,B,C,D)之间扫描线(L1,L2,…,L1280)扫描同时进行,以增加画素点亮时间在一帧图像内的比值(S120)。
