Program wiring instructions

Note:

Power Supply of Display
SMC0430A/SMC0500A: The 3.3V power supply must be connected to 2.8V~3.3V, and 5.0V cannot be connected; SMC0700A: The power supply must be connected to 5.0V, otherwise the backlight will not light;

There are three ways to control the backlight: always on, SSD1963 PWM control brightness, and pin control. By default, pin control is used. Only need to input a high level on the LED_A pin to enable the backlight drive circuit, light the backlight, and input a low level to turn off the backlight. By inputting a PWM signal, the backlight brightness can be adjusted.

Since the power consumption of the product is 200-400mA when the backlight is the brightest, be sure to use a stable power supply and a qualified power supply line.

Absolute Maximum Ratings(Ta=25℃)

Electrical Absolute Maximum Ratings.(Vss=0V ,Ta=25℃)

1. If the module is above these absolute maximum ratings. It may become permanently damaged. Using the module within the following electrical characteristic conditions are also exceeded, the module will malfunction and cause poor reliability.
2. VDD>VSS must be maintained.
3. Please be sure users are grounded when handing LCD Module.

Environmental Absolute Maximum Ratings.

1. The response time will become lower when operated at low temperature.
2. Background color changes slightly depending on ambient temperature.
   The phenomenon is reversible.
3. Ta<=40℃:85%RH MAX.
   Ta>=40℃:Absolute humidity must be lower than the humidity of 85%RH at 40℃.

Electrical Specifications and Timing Characteristics

Electrical characteristics(Vss=0V ,Ta=25℃)

Note:

1. When an optimum contrast is obtained in transmissive mode.
2. Tested in 1╳1chessboardpattern.

LED backlight specification(VSS=0V ,Ta=25℃)

Note:

1. VLED=VLED(+)-VLED(-).
2. The current of LED is 20mA.
   A LED drive in constant current mode is recommended.

Interface signals

Optical Characteristics

Note：The parameter is slightly changed by temperature, driving voltage and materiel
Note 1: The data are measured after LEDs are turned on for 5 minutes. LCM displays full white.
The brightness is the average value of 9 measured spots. Measurement equipment PR-705 (Φ8mm)

Measuring condition:

• Measuring surroundings: Dark room.
• Measuring temperature: Ta=25℃.
• Adjust operating voltage to get optimum contrast at the center of the display.

Measured value at the center point of LCD panel after more than 5 minutes while backlight turning on.

Note 2: The luminance uniformity is calculated by using following formula.

⊿Bp = Bp (Min.) / Bp (Max.)×100 (%)
Bp (Max.) = Maximum brightness in 9 measured spots
Bp (Min.) = Minimum brightness in 9 measured spots.

Note 3: The definition of viewing angle:
Refer to the graph below marked by θ and Ф

Note 4: Definition of contrast ratio.( Test LCD using DMS501)

Note 5: Definition of Response time. (Test LCD using DMS501):
The output signals of photo detector are measured when the input signals are changed from “black” to “white”(falling time) and from “white” to “black”(rising time), respectively. The response time is defined as the time interval between the 10% and 90% of amplitudes.Refer to figure as below.

Note 6: Definition of Color of CIE Coordinate and NTSC Ratio.

Note 7: Definition of cross talk.
Cross talk ratio(%)=|pattern A Brightness-pattern B Brightness|/pattern A Brightness*100

Reliability Test Items and Criteria

Note: Operation: Supply 3.3V for logic system.

The inspection terms after reliability test, as below

Quality level

Classification of defects
Major defects (MA): A major defect refers to a defect that may substantially degrade usability for product applications, including all functional defects(such as no display, abnormal display, open or missing segment, short circuit, missing component), outline dimension beyond the drawing, progressive defects and those affecting reliability.

Minor defects (MI): A minor defect refers to a defect which is not considered to be able to substantially degrade the product application or a defect that deviates from existing standards almost unrelated to the effective use of the product or its operation, such as black spot, white spot, bright spot, pinhole, black line, white line, contrast variation, glass defect, polarizer defect, etc.

Definition of inspection range

For dot defect of TFT LCD which is not smaller than 3 inches, dividing three areas to make a judgment (according to figure 1).
A area : center of viewing area
B area : periphery of viewing area
C area : Outside viewing area
For other defects, dividing two areas to make a judgment (according figure 2).

A zone : Inside Viewing area
B zone : Outside Viewing area
X1(A.A~V.A): 2mm X2(A.A~V.A): 2mm Y1(A.A~V.A): 2mm Y2(A.A~V.A): 2mm

Precautions for Use of LCD Modules

Handling Precautions

1. The display panel is made of glass. Do not subject it to a mechanical shock by dropping it from a high place, etc.
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.
3. Do not apply excessive force to the di splay surface or the adjoining areas since this may cause the color tone to vary.
4. The polarizer covering the display surface of the LCD module is soft and easily scratched. Handle this polarizer carefully.
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
6. Do not attempt to disassemble the LCD Module.
7. If the logic circuit power is off, do not apply the input signals.
8. To prevent destruction of the elements by static electricity, be careful to maintain an optimum work environment.
   1. Be sure to ground the body when handling the LCD Modules.
   2. Tools required for assembly, such as soldering irons, must be properly ground.
   3. To reduce the amount of static electricity generated, do not conduct assembly and other work under dry conditions.
   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.

Storage precautions

1. When storing the LCD modules, avoid exposure to direct sunlight or to the light of fluorescent lamps.
2. The LCD modules should be stored under the storage temperature range.
3. The LCD modules should be stored in the room without acid, alkali and harmful gas.

The LCD modules should be no falling and violent shocking during transportation, and also should avoid excessive press, water, damp and sunshine.
