Note1:When designing of the power supply, take the measures for the prevention of surge

Note2:The power supply lines (Viand GND) may have ripple voltage during luminance control of

LED. There is the possibility that the ripple voltage produces acoustic noise and signal

wave noise in audio circuit and so on. Put a capacitor between the power supply

lines (Viand GND) to reduce the noise if necessary.

Note3:This value excludes peak current such as overshoot current.

Note4:At the maximum luminance control

Note5:A recommended f PWM value is as follows.

Note6:Depending on the frequency used, some noise may appear on the screen,

Please Conduct a thorough evaluation.

Note7:The recommended PWM frequency is 200Hz to 10kHz, but the LED current cannot be

100% proportional to duty cycle, especially for high frequency and low duty ratio.

While the EN signal is high, do not set the tPWH (PWM pulse width) is less than 0.1us.

It may cause abnormal working of the backlight. In this case, turn the backlight off and

then on again by EN signal.

Note8: Optical performance should be evaluated at Ta=25 ℃ only.

If LED is driven by high current, high ambient temperature & humidity condition.

he life time of LED will be reduced.

Operating life means brightness goes down to 50% of initial brightness.

Typical operating life time is estimated data.

5.8 POWER SUPPLY VOLTAGE SEQUENCE

5.8.1 LCD panel signal processing board

* These signals should be measured at the terminal of 100R resistance.

Note1:If there is a voltage variation (voltage drop) at the rising edge of VCC below 3.0V,

there is a possibility that a product does not work due to a protection circuit.

Note2:Display signals (D0+/-, D1+/-, D2+/- and CLK+/-) and function signals (DPS) must

be set to Low or High-impedance, except the VALID period (See above sequence

diagram), in order to avoid the circuitry damage.

If some of display and function signals of this product are cut while this product is

working, even if the signal input to it once again, it might not work normally. If a

customer stops the display and function signals, VCC also must be shut down.

8. Precautions for Use of LCD Modules

8.1 Handling Precautions

8.1.1 The display panel is made of glass. Do not subject it to a mechanical shock by dropping

it from a high place, etc.

8.1.2 If the display panel is damaged and the liquid crystal substance inside it leaks out, be

sure not to get any in your mouth, if the substance comes into contact with your skin or

clothes, promptly wash it off using soap and water.

8.1.3 Do not apply excessive force to the display surface or the adjoining areas since this may

cause the color tone to vary.

8.1.4 The polarizer covering the display surface of the LCD module is soft and easily

scratched. Handle this polarizer carefully.

8.1.5 If the display surface is contaminated, breathe on the surface and gently wipe it with a

soft dry cloth. If still not completely clear, moisten cloth with one of the following solvents:

－ Isopropyl alcohol

－ Ethyl alcohol

Solvents other than those mentioned above may damage the polarizer. Especially, do

not use the following:

－ Water

－ Ketone

－ Aromatic solvents

8.1.6 Do not attempt to disassemble the LCD Module.

8.1.7 If the logic circuit power is off, do not apply the input signals.

8.1.8 To prevent destruction of the elements by static electricity, be careful to maintainan

optimum work environment.

8.1.8.1 Be sure to ground the body when handling the LCD Modules.

8.1.8.2 Tools required for assembly, such as soldering irons, must be properly ground.

8.1.8.3 To reduce the amount of static electricity generated, do not conduct assembly and

other work under dry conditions.

8.1.8.4 The LCD Module is coated with a film to protect the display surface. Be care when

peeling off this protective film since static electricity may be generated.

8.2 Storage Precautions

8.2.1 When storing the LCD modules, avoid exposure to direct sunlight or to the light of

fluorescent lamps.

8.2.2 The LCD modules should be stored under the storage temperature range. If the LCD

modules will be stored for a long time, the recommend condition is:

Temperature : 0 ℃ ～ 40 ℃

Relatively humidity: ≤80%

8.2.3 The LCD modules should be stored in the room without acid, alkali and harmful gas.

8.3 Transportation Precautions

The LCD modules should be no falling and violent shocking during transportation, and also

should avoid excessive press, water, damp and sunshine.
