Note 2: An all white check pattern is used when measuring IDD. f v is set to 60 Hz.
Note 3: For LVDS transmitter input.
Note 4: 1.0A fuse is applied in the module for IDD. For display activation and protection purpose, power
supply is recommended larger than 2.5A to start the display and break fuse once any short
circuit occurred.

Note 1: As Fig. 5.1 shown, LED current is constant, 800 mA, controlled by the LED driver when
applying 12V VLED.
Note 2: Dimming function can be obtained by applying DC voltage or PWM signal from the display
interface CN1. The recommended PWM signal is 1K ~ 10K Hz with 3.3V amplitude.
Note 3: The estimated lifetime is specified as the time to reduce 50% brightness by applying 800 mA at
25 $ C .
