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.

*2) Applied to the voltage drop occurring from terminals VDD, V1, V4 and V5 to each common terminal (C1-C16) when
0.1mA is flown in or out to and from all COM and SEG terminals, and also to voltage drop occurring from terminals
VDD, V2, V3 and V5 to each SEG terminal (S1-S60). When the output level is at VDD, V1 or V2 level, 0.1mA is flown out,
while 0.1mA flow in when the output level is at V3, V4 or V5 level. This occurs when 5 V or -5 V is input to VDD, V1 and
V3 or to V2, V4, and V5 respectively.
