New Stuck Pixel Fixer Released

Califrag has released his version of color flasher (so-called stuck pixel fixer), LUA ColorPlay v16,777,216. In this program written in Lua, it is possible to flash 16-Million color on your screen. You can have the program looping the whole 16M colors on its own, or adjust the range you want it to flash. There is also a battery life display and a world clock setting in the program.

You can download it here.

Here is a detailed lecture about the dead pixel issue and how it can be fixed written by Califrag. Pretty good for reading:

Many wonder what causes stuck or dead pixels? Well it's pretty simple... the psp's screen is made up of tiny transistors and each one controls one pixel on the screen. (480*272=130,560 transistors!!) So it's very possible that one or two transistors might be bad. This causes a DEAD pixel which simply you cannot do anything with... The transistor is dead and you must replace the TFT screen.

Stuck pixels on the other hand, and pixels which have suffered from a voltage spike or drop, and are set a permanent color on the screen. As the screen refreshes, each transistor receives a certain voltage which displays to corresponding color in the pixel. It's possible to unstick these pixels by giving the transistor the right amount of voltage to trigger that color again and get the pixel refreshing correctly. However with so many possible colors it's hard to get the correct voltage to that transistor to trigger that pixel again.

For more information visit [here]. (I would recommend reading the whole article but that goes right to TFT color LCD screens)

The script I coded will cycle through all 16 million + colors in attempt to catch that stuck pixel. The user can choose to cycle through the colors going Forwards, Reverse or even Randomly. You also have the option to manually increment the R G B values +/- 1, flash the screen full black, full white, full red, full green, full blue and take screenshots. There is a built-in clock and battery level indicator as this does suck up the battery juice pretty well.
