A variety of circuit protection devices can be used to help protect LCD screens from damage caused by excessive current or voltage transients. Overcurrent protection may take the form of a fuse or a ...

LCD circuits often require a –10V voltage at 2 to 15 mA to bias a graphics-LCD-driver IC. You can usually accomplish this task with an external charge-pump IC, such as Maxim’s ICL7660, but that ...

[Kaushlesh Chandel] prototyped a few projects on his Arduino that use an HD44780 Character LCD. Wanting to keep these projects in one piece, but not sacrifice his Arduino board, so he etched his own ...

The popularity of Liquid Crystal Displays (LCD) has rapidly soared over the years due to the numerous advantages it offers over other display technologies. This application note provides an ...

Passive circuits for power factor correction (PFC) are simple, reliable, robust, and they don't generate EMI [1-4]. Plus, they offer a low-cost alternative for complying with harmonic current limit ...

The Seventh Circuit’s Nov. 26, 2014, decision in Motorola Mobility LLC v. AU Optronics Corp. FN:1, like its prior (now vacated) decision in the same case could substantially limit the ability of some ...
