Precautions for Light
Light has characteristics to move electrons in the integrated circuitry of semiconductors, therefore
may change the characteristics of semiconductor devices when irradiated with light. Consequently,
the users of the packages which may expose chips to external light such as COB, COG, TCP and
COF must consider effective methods to block out light from reaching the IC on all parts of the
surface area, the top, bottom and the sides of the chip. Follow the precautions below when using the
products.
1. Consider and verify the protection of penetrating light to the IC at substrate (board or glass) or
product design stage.
2. Always test and inspect products under the environment with no penetration of light.

INTRODUCTION
The S6A2067 is a LCD driver lC which is fabricated by low power CMOS technology. Basically this LSl consists of
40 x 2 bit bi-directional shift register, 40 x 2 bit data latch and 40 x 2 bit LCD driver (refer to Figure 1). This lC can be
used as segment driver.
