Standard colour TFT Displays are often unable to provide sufficient levels of brightness for environments offering high ambient light or direct sunlight. As a result you have a display that provides poor image quality.
There are a number of technologies that drastically improve a display's readability in bright conditions, including NLT transflective technology, super high brightness backlights and optical bonded touch panels.
You can switch between Gallery and List view and use the Filters to the right to narrow down the number of panels displayed.
