چکیده
Despite the limited power available in a battery-operated mobile embedded system, its display must have an enough resolution and sufficient color depth to support quality graphical user interfaces and multimedia applications. An LCD (Liquid Crystal Display) is a standard display device, and a color TFT (Thin-Film Transistor) LCD is common even in a low-cost equipment. An LCD display system is composed of an LCD panel, a frame buffer memory, an LCD controller, and a backlight inverter and lamp, as shown in Figure 1. High-resolution, high-color LCDs require large LCD panels, high-wattage backlight lamps and large-capacity frame buffer memories, which together lead to high power consumption.

A Low Power , Passively Cooled 2000 cd / m 2 Hybrid LED - LCD Display
In this paper, we describe a hybrid LEDLCD screen that delivers the same image peak-brightness at 1/2 to 1/20th the power consumption per unit LCD screen area compared to conventional designs. Our architecture is based on an adaptive, spatially controlled LED backlight and a unique algorithm that decomposes the displayed image into LED and LCD components in order to minimize power consumption. ...
متن کاملCircuit Techniques for Low-Power Data Drivers of TFT-LCDs
− A stepwise driving method was used for reducing the AC power consumption in a TFT-LCD. The AC power takes the largest portion of the total power consumption of a TFT-LCD. Experimental results confirmed that the AC power saving efficiency reached up to 75% when a 5-stepwise driving with each step time of 2μ sec was applied to a 14.1 inchdiagonal XGA TFT-LCD. The second largest component of pow...
متن کاملLow-Power Driving Technique for 1-Pixel Display Using an External Capacitor
Liquid crystal displays (LCDs) are suitable as elements underlying wearable and ubiquitous computing thanks to their low power consumption. A technique that uses less power to drive 1-pixel LCDs is proposed. It harvests the charges on the LCD and stores them in an external capacitor for reuse when the polarity changes. A simulation shows that the charge reduction depends on the ratio of the cap...
متن کاملLow Power Consumption Technology for Ultra-High Resolution Mobile Display by Using RGBW System
Battery life and outdoor visibility are two of the most important features for mobile applications today. It is desirable to achieve both low power consumption and excellent outdoor visibility on the display device at the same time. We have previously reported a new RGBW method to realize low power consumption and high luminance with high image quality. In this paper, the basic concept of a new...
