1. OUTLINE

1.1 STRUCTURE AND PRINCIPLE

Color LCD module TM121TDSG02-00 is composed of the amorphous silicon thin film transistor

liquid crystal display (a-Si TFT LCD) panel structure with driver LSIs for driving the TFT (Thin Film

Transistor) array and a backlight.

The a-Si TFT LCD panel structure is injected liquid crystal material into a narrow gap between the

TFT array glass substrate and a color-filter glass substrate.

Color (Red, Green, Blue) data signals from a host system (e.g. signal generator, etc.) are modulated

into best form for active matrix system by a signal processing board, and sent to the driver LSIs which

drive the individual TFT arrays.

The TFT array as an electro-optical switch regulates the amount of transmitted light from the

backlight assembly, when it is controlled by data signals. Color images are created by regulating the

amount of transmitted light through the TFT array of red, green and blue dots.

1.2 APPLICATION

1.3 FEATURES

 High contrast

 Wide viewing angle

 Fast response time

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

Note2: This value excludes peak current such as overshoot current.

Note3: The power supply lines (VDD and 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 (VDD

and GND) to reduce the noise if necessary.

Note5: Depending on the frequency used, some noise may appear on the screen, please conduct a

thorough evaluation.

Note6: While the BRTC signal is high, do not set the tPWH (PWM pulse width) is less than 5 s . It

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

again by BRTC signal.

Note7: Regardless of the PWM frequency, both PWM duty ratio and PWM pulse width must be

always more than the minimum values.

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+/-, D3+/- and CLK+/-) and function signals (DPS and

FRC) 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. PACKING, TRANSPORTATION AND DELIVERY

AVIC will pack products to deliver to customer in accordance with AVIC's packing specifications,

and will deliver products to customer in such a condition that products will not suffer from damage

during transportation. The delivery conditions are as follows.

8.1 INNER PACKING BOX

10 products are packed as the maximum in an inner packing box (See " 8.6 OUTLINE FIGURE

FOR PACKING "). The type name and quantity are shown on outside of the inner packing box,

either labeling or printing. In case the inner packing box with products is dropped from a height of

60cm or more, there is a risk of damage to products.

8.2 OUTER PACKING BOX

The inner box with products is packed in an outer packing box (See " 8.6 OUTLINE FIGURE

FOR PACKING "). The type name and quantity are shown on outside of the outer packing box,

either labeling or printing. In case the outer packing box with products is dropped from a height of

60cm or more, there is a risk of damage to products.

8.3 INSPECTION RECORD SHEET

Inspection record sheets are included in an inner packing box with products. It is summarized to a

number of products for pass/fail assessment.

8.4 TRANSPORTATION

The product is transported by vehicle and aircraft.

9. PRECAUTIONS

9.1 MEANING OF CAUTION SIGNS

The following caution signs have very important meaning. Be sure to read "9.2 CAUTIONS"

and "9.3 ATTENTIONS"!

This sign has the meaning that a customer will be injured or the product will sustain

damage if the customer practices wrong operations.

This sign has the meaning that a customer will be injured if the customer practices

wrong operations.

9.2 CAUTIONS

 Do not shock and press the LCD panel and the backlight! There is a danger of breaking,

because they are made of glass. (Shock: Equal to or no greater than 539m/s and equal to

or no greater than 11ms, Pressure: Equal to or no greater than 19.6 N (  16mm jig))

9.3 ATTENTIONS

9.3.1 Handling of the product

① Take hold of both ends without touching the circuit board when the product (LCD module) is

picked up from inner packing box to avoid broken down or misadjustment, because of stress to

mounting parts on the circuit board.

② When the product is put on the table temporarily, display surface must be placed downward.

③ When handling the product, take the measures of electrostatic discharge with such as earth band,

ionic shower and so on, because the product may be damaged by electrostatic.

④ The torque for product mounting screws must never exceed 0.392N  m. Higher torque might

result in distortion of the bezel.

⑤ The product must be installed using mounting holes without undue stress such as bends or twist

(See outline drawings). And do not add undue stress to any portion (such as bezel flat area).

Bends or twist described above and undue stress to any portion may cause display mura.

⑥ Do not press or rub on the sensitive product surface. When cleaning the product surface, wipe it a

soft dry cloth.

⑦ Do not push or pull the interface connectors while the product is working.

⑧ When handling the product, use of an original protection sheet on the product surface (polarizer)

is recommended for protection of product surface. Adhesive type protection sheet may change

color or characteristics of the polarizer.

⑨ Usually liquid crystals don't leak through the breakage of glasses because of the surface tension

of thin layer and the construction of LCD panel. But, if you contact with liquid crystal by any

chance, please wash it away with soap and water.

9.3.2 Environment

① Do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive

gases. Keep the product in packing box with antistatic pouch in room temperature to avoid dusts

and sunlight, when storing the product.

② In order to prevent dew condensation occurred by temperature difference, the product packing

box must be opened after enough time being left under the environment of an unpacking room.

Evaluate the storage time sufficiently because dew condensation is affected by the environmental

temperature and humidity. (Recommended leaving time: 6 hours or more with the original

packing state after a customer receives the package)

③ Do not operate in high magnetic field. If not, circuit boards may be broken.

④ This product is not designed as radiation hardened.

9.3.3 Characteristics

The following items are neither defects nor failures.

① Characteristics of the LCD (such as response time, luminance, color uniformity and so on) may

be changed depending on ambient temperature. If the product is stored under condition of low

temperature for a long time, it may cause display mura. In this case, the product should be

operated after enough time being left under condition of operating temperature.

② Display mura, flickering, vertical streams or tiny spots may be observed depending on display

patterns.

③ Do not display the fixed pattern for a long time because it may cause image sticking. Use a

screen saver, if the fixed pattern is displayed on the screen.

④ The display color may be changed depending on viewing angle because of the use of condenser

sheet in the backlight.

⑤ Optical characteristics may be changed depending on input signal timings.

9.3.4 Others

① All GND, VCC and VDD terminals should be used without any non-connected lines.

② Do not disassemble a product or adjust variable resistors.

③ See "REPLACEMENT MANUAL FOR LAMP HOLDER SET", when replacing lamp holder

set.

④ Pack the product with the original shipping package, in order to avoid any damages during

transportation, when returning the product to AVIC.
