■ LCD MODULE
This module is an active matrix transmissive LCD display module which enables color display using amorphous silicon TFT (TFT: Thin Film Transis-
tor). The LVDS (Low Voltage Differential Signaling) interface is used for color TFT-LCD panel, driver IC, control circuit, power circuit, and LED back-
light unit. By supplying +12V DC power and +37.5V backlight power,this enables approx. 16.7 million colors of graphics and characters to be
displayed in the 1366 x RGB x 768 dot panel.

■ COIN BATTERY
1 - 5. LED-TCON PWB
Description
1
Function of coin battery
It acts as a backup battery for clock when the display main power is powered off.
2
Failure phenomenon when the battery 
becomes exhausted
The time is cleared while the display main power is off, and the time setting window of OSD 
is displayed when the main power is turned on.
3
PWB supply
It is supplied with the coin battery installed.
4
Voltage that can be judged as battery 
exhaustion
The clock can run when the voltage is 2.0V or more.
5
Usable years
The coin battery life is designed to be about 8 years.
Since the estimated product life is 5 years, the coin battery does not need to be replaced.
Therefore, it is not listed as a consumable part in the parts guide.
