Sony Corp has modified the circuitry for the tiny LCD displays on cellular phones, portable game machines and other handheld devices, reducing power consumption. By lowering the voltage needed to drive the circuitry, the company has developed a display that consumes as much as 25% less power. Sony developed the modifications for the so-called low-temperature polysilicon type of liquid crystal panels that are commonly used for phone displays. It plans to introduce the new technology next year. In a normal low-temperature polysilicon panel, the voltage required to drive the display circuitry fluctuates. Thus, the power supplied from the battery needs to be stepped up to 2.9 volts. By modifying the circuitry on the glass substrate that drives the display, Sony inhibited these fluctuations, enabling the circuitry to run off the battery at 1.8 volts. Sorry no pic
