Car GPS navigator, portable multimedia terminal
Smart home control panel, handheld environmental detection equipment
Small industrial HMI, charging pile auxiliary display
Old 4.3 inch WQVGA screen refurbishment & replacement projects
Power Requirement: LCD logic strictly requires stable DC3.3V; 5V input will cause screen damage
Backlight Notice: No integrated WLED constant current circuit. Must use dedicated LED driver, CCFL inverter cannot be used
Touch Note: Item name mentions touch LCD screen, this panel itself does not come with touch. If touch function needed, match separate resistive/capacitive touch panel and perform OCA bonding
Compatible Model Distinction: TM043NDH02 vs TM043NBH02; same outline, partial optical difference, verify timing before replacement
FPC Cable Handling: Avoid sharp bending of 40Pin flexible cable, prevent ITO circuit breakage and screen flicker
Viewing Restriction: Optimized viewing direction is 12 o’clock; confirm installation direction before assembly
