Densitron 4306BG-HNG LCD Display

The Densitron 4306BG-HNG is an LCD display module built around the T6963C LSI controller, delivering flexible text and graphics rendering through an 8-bit parallel data interface. The module integrates a 128-word Character Generator ROM and supports up to 8KB of external display RAM, enabling independent allocation of text, graphics, and custom character data with freely repositionable display windows. The T6963C controller features auto write/read functionality for efficient sequential data transfer without per-datum command overhead, plus screen peek capability for reading combined text and graphic data states.

Technical Specifications

Controller: T6963C LSI

Data Interface: 8-bit parallel bus with MPU control lines

Onboard Memory: 128-word Character Generator ROM (CGROM)

External Display RAM: Up to 8KB (text, graphics, external CG data)

Display Window: Freely movable within allocated memory range

Auto Write/Read Mode: Sequential data transfer with automatic address pointer increment; disables other command acceptance during operation

Screen Peek Command: Reads logical text/graphics combination; sets status flag (STA6) when address pointer is outside graphic area

Key Features

Display Modes: Positive (dark pixels on light background) and negative (light pixels on dark background)

Backlight Options: Array (direct, uniform brightness), edge (low power, thin profile), LED (up to 100,000 hour life, vibration/shock rated, multiple colors), EL (up to 8,000 hours, low current, thin profile, requires inverter)

Polarizer Types: Reflective (ambient light dependent), transflective (all-light operation with mirror reflector), transmissive (continuous backlight, low ambient applications)

Logical Text/Graphics Combination: Supports simultaneous character and graphic display data rendering

Typical Applications Industrial control interfaces, embedded system HMI, portable instrumentation, and environments requiring switchable display modes and flexible memory allocation.

Compatibility & Integration Direct MPU interface via 8-bit parallel bus. Static electricity protection required during handling to prevent discharge damage.
