02 / OEM DESIGN
Make the display fit your product.
Bring your requirements. We will review the configuration with you.
Reading position
The reference specifies a 6 o’clock viewing direction. Evaluate contrast and illumination from the intended rider position.
Driver and segment allocation
Review the speed digits, scale and status icons against the COM/SEG table and the stated LCD drive condition.
03 / APPLICATION DIRECTION
Motorcycle instruments
Assess the speed, distance, fuel and warning information required by a motorcycle instrument. Confirm the complete assembly against the intended viewing position, illumination and vehicle conditions; display symbols do not establish sensors or vehicle approval.
04 / PRODUCT SUPPORT
From reference to your design.
Are the speed and warning symbols sensing functions?
They are LCD artwork. Vehicle signals, sensors and warning logic are supplied by the host system.
Is the 5.0 V value a complete module power rating?
It is the documented LCD operating voltage. Driver circuitry and illumination require their own electrical review.
