Hello again everyone, If anyone here has an appreciation for hardware engineering nuances, and has ever wondered how mobile phone LCD backlight LEDs are driven, you may find my write-up interesting:
https://www.freecalypso.org/hg/freecalypso-hwlab/file/tip/doc/LCD-backlight-driver In this article I have described what I desire for my FreeCalypso dream phone in terms of its LCD and backlight, how the LCD backlight is implemented in Motorola C139 and C155 phones according to the available schematics and why I dislike that approach, and my proposed alternative. My proposed alternative also has its flaws which I have explained in my write-up, but it is the best I've been able to come up with so far. In the article I also cover how I have practically implemented my novel backlight LED driver circuit on our current Luna LCD board, and the experience of how it actually works. If anyone here has better EE knowledge than I do, or has better experience with driving LEDs specifically, and can recommend a better approach than what I have come up with so far, I am all ears! Still enthused for now, Mother Mychaela _______________________________________________ Community mailing list Community@freecalypso.org https://www.freecalypso.org/mailman/listinfo/community
