It was a little over a year old -when it happened, way too soon to give up on it, so I decided to take -it apart and replace the screen if possible. - -If you want to open any device that is held together by plastic parts -with teeny plastic flaps that snap into each other: use a guitar -pick. The Jazz III pick (my favourite) is very well suited for the -job. I used it to pry apart the plastic frame of my netbook before. -The Kobo touch is really a beautiful device (if you have one, I -encourage you to look inside) and is much easier to take apart than my -netbook. The battery is much smaller than I expected and the PCB is -very clean and ordered. - -The screen is glued to a very robust frame (metallic, looks like iron) -with two stripes of adhesives; with some nudging I could separate the -two components. The screen's backside is shiny, polished; -mesmerizing. If you want to keep it that way, don't touch it with your -filthy fingers. - -Originally, I wanted to take the opportunity to upgrade the screen to -whatever model is compatible with the driver chip. This is printed on -the chip: - - E INK - TPS65185 - TI 181 - A49F G4 - -As it was difficult to get detailed documentation on the types of -panels that can be used with the chip I decided to simply get the same -model as the broken screen: ED060SCE LF T1. The same screen seems to -be used in the Nook. - -I paid CNY 180 for a replacement. It appears to be a more recent -revision of the screen; there's a little IC on the flexible connector -and a few numbers on the labels have changed. It works fine, though -ghosting seems to be significantly worse. The Kobo UI doesn't always -force a full page refresh; this only really affects the library -browser, though. (The refresh rate can be configured for reading -mode.) The more often a part of the screen is updated the more gray -noise appears all over the screen. \ No newline at end of file -- cgit v1.2.3
