Organic electroluminescent display device

Pub Date: 2007-05-24

Pub Number: US20070118781

An organic electroluminescent display device employing a demultiplexer to reduce the number of output lines of a data driver. The display device uses the demultiplexer to store a data voltage in a data line, and supplies the stored data voltage to a pixel when a scan signal is applied, thereby displaying an image. Here, the data voltage supplied to the pixel is lowered because an electric charge is shared between a data line capacitor and a storage capacitor in the pixel. To compensate for the lowered data voltage, an auxiliary capacitor is provided for generating a compensation voltage. Here, the auxiliary capacitor increases the data voltage according to a level change of the scan signal. Therefore, a decrease in level of the voltage applied to the pixel is reduced or prevented so that DC/DC efficiency is enhanced without lowering a power supply voltage and a reference voltage.

Methods and algorithms for cell enumeration in a low-cost cytometer

Pub Date: 2007-05-24

Pub Number: US20070117158

The enumeration of cells in fluids by flow cytometry is widely used across many disciplines such as assessment of leukocyte subsets in different bodily fluids or of bacterial contamination in environmental samples, food products and bodily fluids. For many applications the cost, size and complexity of the instruments prevents wider use, for example, CD4 analysis in HIV monitoring in resource-poor countries. The novel device, methods and algorithms disclosed herein largely overcome these limitations. Briefly, all cells in a biological sample are fluorescently labeled, but only the target cells are also magnetically labeled. In addition, non-magnetically labeled cells are imaged for viability in a modified slide configuration. The labeled sample, in a chamber or cuvet, is placed between two wedge-shaped magnets to selectively move the magnetically labeled cells to the observation surface of the cuvet. An LED illuminates the cells and a CCD camera captures the images of the fluorescent light emitted by the target cells. Image analysis performed with a novel algorithm provides a count of the cells on the surface that can be related to the target cell concentration of the original sample. The compact cytometer system provides a rugged, affordable and easy-to-use technique, which can be used in remote locations.
