For surface termination, please wipe off with alcohol. • The liquid used in the LCD panel is a harmful substance and must not be licked or awallowed. If you touch this liquid, wash it out completely. • Do not touch IC lead and terminal. • Do not expose to direct sunlight for a long period of time and if it will be used at direct sunlight, recommend to use UV cut filter. • For storage please avoid in high temperature, high humidity. When long-term storage is required, keep the panels in low temperature (5°C ∼ 25°C) and low humidity. • To prevent TAB damage, TAB bent time must be up to twice. (2) Operational instruction • Please do not connect or take away the LCD module to the system in the condition of power on. • Please input signal after LCD module power is turned on when turning off. Please turn off from input signal. In worst case IC can be broken by ratch up phenomenon. (3) Mounting instruction • In the circuit CMOS-IC is used. Please be careful for ESD. • Protection sheet is put on LCD module surface and back side. At removing the sheet, electric static is generated. So it must be removed slowly and recommend to use Ion blower etc. (4) Cautions for LCD with FPC • Do not pend nor pull FPC. • Do not hold FPC with fingers directly nor suspend FPC. • When bending FPC, keep 5mm from the edge of grass (FPC joint) and bend toward Mother board side. (5) Production • Production in Japan or China.
