    Abstract: In this paper, a sequential color light emitting diode (LED) backlight driving system for liquid crystal display (LCD) panels with area control is proposed. Due to improvement on luminous efficacy, fast response, long life, mercury free, and wide color gamut, LED has gradually substituted for cold cathode fluorescent lamp (CCFL) as backlight. Although some novel CCFLs with low content of mercury and wide color gamut have been proposed, it is difficult to shorten their on-off transition. Recently, a novel display technique, namely area control, requiring backlights with fast response has been proposed to improve the contrast ratio of LCD and reduce power consumption of the backlights. With the area control, a panel is partitioned into several areas, and the back-tight brightness of each area is controlled individually. In addition, color sequential display (CSD) is introduced to further reduce the power consumption. A sequential color LED backlight driving system with area control has been built, from which experimental measurements have verified the feasibility of the proposed driving system.
