HL19264A 192×64 Graphic LCD Module, 5V 8-Bit Parallel, COB

The HL19264A 192×64 graphic LCD module supports custom graphics and text through an 8-bit parallel interface. A 5V supply, 20-pin connection, and built-in negative voltage generator support equipment display integration.

The HL19264A is a 192×64 graphic LCD module designed to display text, symbols, and custom graphics in equipment interfaces. Its chip-on-board construction combines a 192 × 64 dot matrix with a 5.0V supply and a 20-pin connection. A built-in negative voltage generator supports LCD contrast control.

Suitable applications include industrial control panels, measuring instruments, and equipment status displays. The 8-bit parallel interface provides register selection, read/write control, enable, three chip-select signals, and an active-low reset. Integration requires checking contrast settings, mechanical clearance, and the optical configuration of the ordered variant against the final approved drawing.
