General Description:
This Open-cell is a color active matrix LCD open-cell incorporating Oxide TFT (Thin Film Transistor).It is composed of a color TFT-LCD panel, driver ICs, a control circuit and power supply circuit. Graphics and texts can be displayed on a 1920×3×1080 dots panel with 16,777,216 colors by using eDP (Embedded Display Port) Ver1.2 interface and supplying +3.3V DC supply voltage for TFT-LCD panel driving. In this TFT-LCD panel, color filters for excellent color performance is incorporated to realize brighter and clearer pictures, making this open-cell optimum for use in multi-media applications. Optimum viewings are in all directions. Without Backlight-driving LED controller. eDP transfer rate specification: 2.7Gbps/2 lane.

The measurement shall be taken 30 minutes after lighting the module at the following rating.
Condition: PWM Duty = 100%
The optical characteristics shall be measured in a dark room or equivalent.
Matters Needing Attention:
1.Be sure to turn off the power supply when inserting or disconnecting the cable.Please insert for too much stress not to join a connector in the case of insertion of a connector.
2.Be sure to design the cabinet so that the module can be installed without any extra stress such as warp or twist.
3.Since the front polarizer is easily damaged, pay attention not to scratch it.
4.Wipe off water drop immediately. Long contact with water may cause discoloration or spots .
