JKBMS JIKONG PB Series Display Guide: LCD 4.3 vs. LCD 7.0
Quick answer: PB-series boards use the LCD 4.3-TTL or LCD 7.0-TTL display. The stated difference between these two options is screen size: LCD 7.0 has a larger viewing area for easier operation and viewing battery information. Our battery-box panels generally accommodate LCD 4.3 by default; choosing LCD 7.0 requires the customer to manually enlarge the panel opening. Check the exact product configuration before ordering.

Shop compatible PB displays
For PB V19 boards, shop the dedicated TTL-P models: LCD-4.3-TTL-P or LCD-7.0-TTL-P. These PB-only displays are not for B/BD boards.
This guide shows the PB display interfaces and example screens to help you recognize the LCD 4.3-TTL and LCD 7.0-TTL options.
Installation: check the panel opening
Our battery-box panels are generally designed for the 4.3-inch display opening. If you choose the 7.0-inch display, you will need to manually enlarge the panel opening. Confirm the mounting requirements for your exact cabinet and display before ordering or modifying the panel. This mounting guidance does not specify which display is included with every kit; check the selected product configuration.

Frequently asked questions
Which displays are compatible with PB-series boards?
Choose the PB-compatible LCD 4.3-TTL or LCD 7.0-TTL model.
What is the difference between LCD 4.3 and LCD 7.0?
The stated difference is screen size. LCD 7.0 has a larger display area, which can make operation and viewing battery information easier.
Will the LCD 7.0 fit the default battery-box panel opening?
The default panel opening generally accommodates LCD 4.3. Choosing LCD 7.0 requires the customer to manually enlarge the opening. Check your exact cabinet and display before purchase.
Where are the PB display connectors?
The UART port and display interface are both on the PB protection board (main board), not on the separate interface board. Both connect to the compatible display and differ in connector type. PB PC host software communication instead uses an RS485-to-USB cable through the interface board's RS485 port. See the PB interface guide for board photos and explanations.
Can a PB 4.3-TTL display be substituted for a B/BD 4.3-inch display?
No. The PB-series 4.3-TTL display and B/BD-series 4.3-inch display are different specifications and are not interchangeable.
