2. LCD Panel Operations
[Description of basic operations]
The basic operations of the LCD panel are shown below based on the wide-display mode.
A vertical driver, which consists of vertical shift registers, enable-gates and buffers, applies a selected pulse
to every 225 gate lines sequentially in every single horizontal scanning period.
A horizontal driver, which consists of horizontal shift registers, gates and CMOS sample-and-hold circuit,
applies selected pulses to every 1068.5 signal electrodes sequentially in a single horizontal scanning period.
Vertical and horizontal shift registers address one pixel, and then dot Thin Film Transistors (TFTs; two TFTs
for one dot) turn on to apply a video signal to the dot. The same procedures lead to the entire 480

1068.5
dots to display a picture in a single vertical scanning period.
The LCD pixel dots are arranged in a delta pattern, where the dots connected to the identical signal line are
positioned with 1.5-dot offset against those of the adjacent horizontal line. Horizontal Start Pulse (HST) is
generated with 1.5-bit offset between the horizontal lines to regulate the above offset. HCK and sample-hold
(S/H) pulses follow the same 1.5-bit offset scheme.
The video signal must be input with polarity-inverted system in every horizontal cycle.
Timing diagrams of the vertical and the horizontal display cycle are shown below.
