CANNY Elevator LCD Display Board KLL-DV20C-311B

CANNY Elevator LCD Display Board KLL-DV20C-311B is used in CANNY elevator display and landing operating panel applications.

This board is normally related to elevator floor indication, landing display, hall call display, or LOP display signal output depending on the original elevator configuration. In the elevator spare parts market, it may also be searched as:

• CANNY Elevator LCD Display Board
• CANNY Elevator Display Board
• CANNY LOP Display Board
• CANNY Landing Display Board
• CANNY Hall Call Display Board
• CANNY Elevator Indicator Board
• CANNY Elevator PCB Display Board

The main model reference for this page is:

• KLL-DV20C-311B

Related model references may include:

• KLL-DV20C
• KLL-DV20CV12-5
• KLL-DV20

These related references are useful for search coverage and quotation confirmation. However, KLL-DV20C-311B should still be confirmed by the complete old board label before replacement.

LCD Display Application

KLL-DV20C-311B should be treated as an elevator LCD display board, not a main control board or door control PCB.

It may be installed in the landing operating panel, hall display unit, or other elevator display assembly. Depending on the elevator system, the board may support floor number display, direction indication, call status display, or related passenger information output.

Because display boards are often installed behind a faceplate, the front appearance alone is not enough for accurate replacement. A similar-looking display may use a different PCB version, connector direction, display format, or mounting structure.

Model and Version Confirmation

For this product, the suffix matters.

KLL-DV20C-311B may be related to the KLL-DV20C display board family, but the 311B suffix should not be ignored. It may represent a specific board version, display configuration, or site matching requirement.

Before ordering, please confirm:

• Complete KLL-DV20C-311B marking on the old board
• Whether KLL-DV20C or KLL-DV20CV12-5 appears on the PCB
• Front and back photos of the display board
• Connector quantity and connector direction
• Display window size
• Landing panel or display assembly photo
• Whether the board is used in LOP, HOP, COP, or another display position
• Existing display fault description from the maintenance technician

If the old label is unclear, a full photo of the display assembly is usually more useful than only providing the elevator model.

Common Display Fault Situations

Maintenance teams may check this board when the elevator display has problems such as:

• no floor display
• dim LCD screen
• wrong floor indication
• direction display abnormality
• display flickering
• display not responding after power-on
• visible PCB or connector damage

These symptoms may also be caused by power supply problems, signal cable failure, connector oxidation, landing button board issues, or controller-side communication faults. The complete display signal path should be checked before confirming the LCD display board fault.

Practical Replacement Notes

Do not select KLL-DV20C-311B only by appearance.

CANNY elevator display boards may look similar from the front, but the rear PCB, connector position, display size, signal definition, and installation frame may be different. Before installation, technicians should compare the old and new board carefully and check the surrounding wiring condition.

For overseas buyers, sending clear photos of the original KLL-DV20C-311B board, connector area, display window, and complete panel assembly is the safest way to reduce wrong supply before shipment.
