ACX306BKU
3.86cm (1.5-type) NTSC/PAL Color LCD Panel Module with LED Backlight
Description
The ACX306BKU is an LCD panel module with LED
backlight developed exclusively for the ACX306BKU
3.86cm diagonal active matrix TFT-LCD panel
addressed by low temperature polycrystalline silicon
transistors with built-in peripheral driving circuitry.
This module provides full-color representation for
NTSC and PAL systems. In addition, RGB dots are
arranged in a delta pattern that provides smooth
picture quality without fixed color patterns compared
to vertical stripe and mosaic patterns.
Features
• Total module thickness: 3.09mm (typ.) ultra-thin type, narrow frame
• Low voltage, low power consumption: 12V drive, 43mW (panel block, typ.)
• Number of active dots: 118,000 dots, 3.86cm (1.5-type) in diagonal
• Center luminance
Standard mode:
170cd/m2 (backlight 144mW typ.)
High luminance mode: 200cd/m2 (backlight 185mW typ.)
• Horizontal resolution: 240 TV lines
• Optical transmittance: 7.5% (typ.)
• High contrast ratio with normally white mode: 200 (typ.)
• Built-in H and V driving circuitry (built-in input level conversion circuit, 3V drive possible)
• Smooth pictures with a RGB delta arrangement
• Supports NTSC/PAL
• Built-in picture quality improvement circuit
• Up/down and/or right/left inverse display function
• Dirt-resistant surface treatment
Element Structure
• Active matrix TFT-LCD panel with built-in peripheral driving circuitry using low temperature polycrystalline
silicon transistors
• Number of pixels
Total number of dots:
494 (H) × 242 (V) = 119,548
Number of active dots:
490 (H) × 240 (V) = 117,600
• Module dimensions
Package dimensions:
37.0 (W) × 31.94 (D) × 3.09 (H) (mm)
Effective display dimensions: 31.115 (H) × 22.86 (V) (mm)
Applications
Digital still cameras
