12) Procedure to insert mating connector
When the mating connector is inserted, it should be parallel to the connector on the LCD module and it
should be inserted horizontally. Do not leave a gap beh>een two connectors.
13) The module should be driven according to the specified ratings to avoid malfunction and permanent damage.
Applying DC voltage causes a rapid deterioration of LC material. Make sure to apply alternating waveform
by continuous application of the M signal. Espe&&& power ON/OFF sm

14) LCD retains the display pattern when it is applied for long time.(Image retention)
To prevent image retention. do not apply the flied pattern for along time.
15) Image retention is not a deterioration of LCD. It will be removed after display pattern is changed
16) CCFI’ backlight should be kept OFF during VDD is “L” level.
Precautions for touch panel
1) Designing
1. Active area
Active area is defined as input area by pen or finger. Its function, optical properties and durability
are specified in the specifications.
a) Detection of coordinates and calbration must always be conducted within active area. If those are
conducted outside of the active area, those may cause functional errors.
b) Area which is actually accessed by pen or finger must be designed within active area. If it is
designed outside of the active area, it may cause functional error.
2.Neutral area
Neutral area is located around the active area for l.Omm wide. Although the coordinates can be detected
in this area, its functionality, optical properties and durability are not assured.
a) Neutral area detects coordinates when input by pen or finger, but it may cause functional error
when it is treated as detected data.
b) As the purpose of the neutral area is to protect inactive area, pushing hardly by pen tip or others
may cause deterioration of its durability.
3.Visible area
This is transparent area where silver electrode or flex printed with opaque ink are not existing.
It assures qualities related to appearance standards defined in the specifications.
4Jnactive area
Upper electrode or lower electrode in the inactive area is printed with transparent insulation ink on it.
It is located outside of the active area and a non functional area.
a) Inactive area is printed with insulation ink. Hard push action may cause a deformation of upper
electrode film and may lead to a malfunction in the active area nearby. Upper electrode may come
