each pixel of the display to properly display an image. During the
erasing scan, just enough voltage in a reverse polarity is applied
to a particular pixel to erase the voltage applied to the
particular pixel in the display writing scan.
Claim 1 is illustrative of the invention and reads as
follows:1
1. A display control method for a liquid crystal display unit
which includes two polarizing plates, each polarizing plate having
a polarizing axis, the polarizing plates being disposed in
directions along which the respective polarizing axes cross at
right angles with each other; a liquid crystal panel sandwiched
between the polarizing plates, the liquid crystal panel having a
plurality of pixels; a back light disposed at the back of the
liquid crystal panel, the back light being composed of a light
source, and a light-emitting region, the light-emitting region
guiding red, green, and blue light emitted from the light source
into the liquid crystal panel; a plurality of switching elements,
at least one switching element being provided for each one of the
plurality pixels, selective ones of the switching elements being
ON/OFF driven in response to red, green, and blue data of selected
ones of the plurality of pixels during a period of respective
display cycles, and at the same time, red, green, and blue light of
the back light being emitted in a time-sharing manner in
synchronism with the ON/OFF driving of corresponding ones of the
plurality of switching elements during the period of respective
display cycles, said method comprising:
a first scanning for displaying individual ones of the
plurality of pixels of the liquid crystal panel; and
