LCD Module
ALR122FNX
Low-Temperature Polysilicon
1.5-inch TFT LCD Module
Overview
This 1.5 inch reflective type low temperature poly-silicon TFT-LCD module consists of reflective type LCD panel
and white LED fr ont light. This is suitable for DSC.
Features
• Diagonal 3.8cm (1.5 inch) display size.
• 521 × 218 = 113,578 dots.
• RGB delta color arrangement.
• Reflective type low temperature poly-silicon TFT-LCD.
• Operating temperature (Panel) is -10 to +60°C. Ambient temperature during storage is -20 to +70°C.
• Slim design, li gh tweight and nar row frame.
• Up / down and right / left function.
• Built-in shifter circuit.
• Conform to NTSC / PAL by using recommended IC : LV4135W, LV4137W (LV4139W : Under development).
• PTME (Partially Tilted Mirror Electrode) is used for Reflector.
Combination of PTME and Diffusion film realizes high-reflection and high-contrast.
• Good visibility is realized by the front light with every environment.
• White-LED type Front light (Inverter is unnecessary).
