The present invention discloses a pixel display configuration by providing
a voltage controller in each pixel control circuit for controlling the
voltage inputted to the pixel electrodes. The controller includes a
function of multiplexing the voltage input to the pixel electrodes and
also a bit buffering and decoupling function to decouple and flexible
change the input voltage level to the pixel electrodes. The controller
further includes a first switching stage and a second switching stage and
each stage has a P-type transistor and a N-type transistor to expand the
range of the switching voltages such that the improvement of the pixel
control is further enhanced. The rate of DC balancing can be increased to
one KHz and higher to mitigate the possibility of DC offset effects and
the image sticking problems caused by slow DC balancing rates. This
invention further discloses an enabling technology for switching from one
DC balance state to another without rewriting the data onto the panels.
Therefore, it is not required to implement a high voltage CMOS designs
and standard CMOS technologies can be applied to manufacture the storage
cells and control panel for the LCOS displays with lower production cost
and higher yields.
