摘要：
System-on-chip (SoC) mobile thin-film transistor (TFT) liquid-crystal display (LCD) drivers are, to a certain extent, inadequate to support portable devices that require higher driving currents for their high resolution and large LCD panels. In this paper, we will show how a simple boost converter can be designed and used in the display driver for high current demand TFT-LCD panels. The proposed driver circuit is partitioned in a way that the current chip-on-grass (COG) package technology used by the traditional mobile display driver can be maintained in order to save production cost. A prototype of the controller of the proposed power converter is designed with a standard 0.13-mu m HV CMOS process. Compared with traditional designs, the proposed circuit shows its support on higher output currents with improved power efficiency and output voltage variation.
