(2) Ripple of supply voltage

Please note that the ripple at the input connector of the module should be within the values shown in this table.

If the ripple is beyond these values, the noise may appear on the screen.

VDD

(for logic and LCD driver)

Acceptable range

≤ 100 mVp-p

Note The acceptable range of ripple voltage includes spike noise.

VDDB

(for backlight)

≤ 200 mVp-p

Examples of the power supply connection

a) Separate the power supply

b) Put the filter

(3) Inverter current wave

In the luminance control mode, the rush current below flows into the inverter of the module. The duty cycle

varies from 100% through 20% depending on the luminance control level. This might cause the noise on the

screen. Please evaluate the appropriate value of the capacitor in the filter to eliminate the noise.
