Epson S1D15106 segment LCD driver

Epson’s S1D15106 is a greyscale segment LCD driver for instrumental cluster display systems. It has been designed in response to the increase in the number of combination-type instrumental cluster displays that use TFT LCDs for things that require display flexibility and that use segment LCDs for fixed items such as indicators and icons.

The LCD driver can be directly connected to a microcontroller. Image data transferred from the microcontroller can be displayed on the segment display without an external memory. Static driving enables high contrast, while pulse-width modulation (PWM) enables the 16-level greyscale segment display, making the driver suitable for the visualisation of things such as speedometers and tachometers.

The driver circuit is equipped with display safety functions such as segment/common output problem (open/short) detection. If a line from driver output to display is open and a display abnormality is detected, the display can be restored by switching the driver output terminal via control from the microcontroller. The driver satisfies the strict quality requirements for automotive products and is compliant with AEC-Q100, operating at temperatures up to 105°C.
