2．Overview
LD-24604C- 2
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 and a White-LED
Backlight unit. Graphics and texts can be displayed on a 800×RGB×600dots panel with about 262144
colors by using LVDS (Low Voltage Differential Signaling) and supplying +3.3V DC supply voltages for
TFT-LCD panel driving and supply voltage for backlight.
The maximum viewing angle is in the 6o'clock direction.
The 12o'clock direction is difficult to reverse the grayscale.
By the independent RGB gamma adjustment function, this module can display natural gray scales.
The LED driver circuit and the PWM circuit to drive the backlight are built into the module.

Duty 10% : Min. Luminance (0%：LED OFF)
Duty 100% : Max. Luminance
Luminance changes in proportion to the duty ratio. (t13≧500μs)
When the frequency slows, the display fineness might decrease.

【*6】 Luminance becomes 50% of an initial value. (Ta＝25℃, PWM=100%)
