2. Overview
This module is a color active matrix LCD module incorporating amorphous silicon TFT (Thin Film Transistor). It is
composed of a color TFT-LCD panel, driver ICs, control circuit, power supply circuit, inverter circuit and back light
system etc. Graphics and texts can be displayed on a 1920 RGB 1080 dots panel with 16,777,216 colors by
using LVDS (Low Voltage Differential Signaling) to interface, +12V of DC supply voltages.
This module also includes the DC/AC inverter to drive the CCFT. (+24V of DC supply voltage)
And in order to improve the response time of LCD, this module applies the Over Shoot driving (O/S driving)
technology for the control circuit .In the O/S driving technology, signals are being applied to the Liquid Crystal
according to a pre-fixed process as an image signal of the present frame when a difference is found between image
signal of the previous frame and that of the current frame after comparing them.
By using the captioned process, the image signals of this LCD module are being set so that image response can be
completed within one frame, as a result, image blur can be improved and clear image performance can be realized.

[Note] Lamp life time is defined as the time when brightness becomes 50% of the original value
in the continuous operation under the condition of Ta=25 and brightness control(VBRT=3.3V).
Above value is applicable when the long side of LCD module is placed horizontally
(Landscape position).
(Lamp lifetime may vary if LCD module is in portrait position due to the change of
mercury density inside the lamp.)

About the relation between data input and back light lighting, please base on the above-mentioned input sequence.
When back light is switched on before panel operation or after a panel operation stop, it may not display normally.
But this phenomenon is not based on change of an incoming signal, and does not give damage to a liquid crystal
display.
