| Most electronic devices, portable computers, and desktops use liquid crystal or light-emitting diode technology in their display. LCD and LED technologies are well refined, but still have disadvantages such as grain boundaries in the panel result in low-drivability pixels or dead pixels. The voltage supplied to the panel must be higher in order to account for the low-drivability pixels and large scale displays still suffer from defective pixels. There is a need to increase the yield of large panel displays and decrease the power requirements of those used in portable devices. Purdue University researchers have devised a new method for the design of LCD and organic LED based displays that compensates for defective and low-drivability pixels. Using this method, the voltage requirements of small LCD panels were decreased by 20 percent with no drawback in brightness or performance. In large panel displays, the yield was increased by 7 percent with a negligible increase in power requirements. Advantages: -Design compensates for defective and low-drivability pixels -Decreased voltage requirements Potential Applications: -Electronics industry -LCD and LED manufacturers |
