Backlight driver for DT070BTFT-PTS1
Submitted by Jaisankar_av on June 4, 2019
Hi,
We are using DT070BTFT-PTS1 LCD in our design and the backlight is not working with the 9.6V DC-DC power supply with series resistor (R175 =75Ohm) to control 140mA.
The display does not have any brightness.
Attaching the power supply section for the backlight. Pls refer and let us know what could be wrong. Appriciate your quick reply.
Regards,
J
