Sony PSP-E1002 Instruction Manual page 8

LCD screen
 The LCD screen is made of glass and may crack if subjected to
excessive force.
 Pixels that are not lit or are continuously lit may appear in
certain locations on the LCD screen. The appearance of such
spots is a normal occurrence associated with LCD screens and
is not a sign of a system malfunction. LCD screens are made
using highly precise technology. However, a very small number
of dark pixels or continuously lit pixels exist on each screen.
Also, a distorted image may remain on the screen for several
seconds after the system has been turned off.
 Direct exposure to sunlight may damage the system's LCD
screen. Be careful when using the system outdoors or near a
window.
 When using the system in a cold environment, you may notice
shadows on the graphics or the screen may appear darker than
usual. This is not a malfunction, and the screen will return to
normal when the temperature goes up.
 Do not leave still images displayed on the screen for an
extended period of time, as doing so may cause a faint image to
be left permanently on the screen.
