1. Application
This specification applies to a color TFT-LCD module, QD141X1LH03.

2. Overview
This module is a color active matrix LCD module incorporating amorphous silicon TFT
(Thin Film Transistor). It is composed of a color TFT-LCD panel, driver ICs, control circuit
and power supply circuit and a backlight unit. Graphics and texts can be displayed on a

4

1024×3×768 dots panel with 262,144 colors by using LVDS (L

ignaling) to interface and supplying +3.3V DC supply voltage for TFT-LCD panel driving

S
and supply voltage for backlight.
The TFT-LCD panel used for this module has very high aperture ratio. A low-reflection and
higher-color-saturation type color filter is also used for this panel. Therefore, high­brightness and high-contrast image, which is suitable for the multimedia use, can be
obtained by using this module.
Optimum viewing direction is 6 o'clock.

[Features]

1) High aperture panel; high-brightness or low power consumption.

2) Brilliant and high contrast image.

3) Small footprint and thin shape.

4) Light weight.

10. Display Quality
The display quality of the color TFT-LCD module shall be in compliance with the Incoming
Inspection Standard.

11．Handling Precautions
a) Be sure to turn off the power supply when inserting or disconnecting the cable.
b) Be sure to design the cabinet so that the module can be installed without any extra

stress such as warp or twist.
c) Since the front polarizer is easily damaged, pay attention not to scratch it.
d) Wipe off water drop immediately. Long contact with water may cause discoloration or

spots.
e) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
f) Since the panel is made of glass, it may break or crack if dropped or bumped on hard

surface. Handle with care.
g) Since CMOS LSI is used in this module, take care of static electricity and injure the

17

human earth when handling.
h) Observe all other precautionary requirements in handling components.
i) This module has its circuitry PCBs on the rear side and should be handled carefully in

order not to be stressed.
j) Laminated film is attached to the module surface to prevent it from being scratched .

Peel the film off slowly just before the use with strict attention to electrostatic charges.
Ionized air shall be blown over during the action. Blow off the 'dust' on the polarizer by
using an ionized nitrogen gun, etc..

K) Black PET sheet covers some electric components and handle with special care to

avoid mechanical stress and shock on this PET surface.

L) Mounting screw hole can stand torque 1.3~1.5 Kgf-cm.

Incoming Inspection Standards for TFT-LCD Modules

1) Scope
These incoming inspection standards shall apply to TFT-LCD modules (hereinafter called
“Module”) supplied by QDI Corporation (hereinafter called “Seller”) to Quanta
(hereinafter called the “Buyer”).

2) Incoming inspection
The Buyer shall have the right to conduct at its own cost and expense, an incoming
inspection of the Module’s at the destination specified in the relevant bills of landing in
accordance with the Module’s specifications separately agreed upon and the inspection
standard set forth in this Article. The Buyer shall notify the Seller writing of a result of
such inspection judgment (acceptance or rejection) in accordance with the said

19

inspection standard within 40 days after the date of the bills of landing. Should the Buyer
fail to so notify the seller within the said 40 days period, the Buyer’s right to reject the
Module’s shall then lapse, and the said Module’s shall be deemed to have been accepted
by the Buyer.

3) Method of incoming inspection
Unless otherwise agreed in writing, the method of incoming inspection shall be in
accordance with a sampling inspection based on MIL-STD-105E.

4) Classification of defects
Defects are classified as major defect and a minor defect according to the degree of
defect defined herein.

a) major defect

A major defect is a defect that is likely to result in failure, or to reduce materially
the usability of the product for its intended purpose.

b) Minor defect

A minor defect either is a defect that is not likely to reduce materially the usability
of the product for its intended purpose, or is a departure from an established

having little bearing on the effective use or operation of the product.
Specific criteria of judgment on major and/or minor defects or otherwise shall be in
accordance with the attached “Classification of Defect.”

5) Acceptable quality level (“AQL”)
The AQL for major and minor defects shall be respectively set forth below.

a) Major defects : AQL :0.4

QD141X1LH03A2 Page

b) Minor defects : AQL:1 Based on overall evaluation

6) Method of sampling inspection

a) Lot size : Quantity per shipment lot per mode
b) Sampling type : Normal inspection, Single sampling
c) Inspection level : II
d) Sampling table : Table in MIL-STD-105E
e) Inspection conditions : The inspection conditions shall be as in the LCD

specifications. The environmental conditions and the visual inspection shall be as
follows:

(i) The environmental conditions

Room temperature: 20-25°C
Humidity: 65±20%RH

(ii) The external visual inspection: The inspection shall be conducted by using a

20

single 20W fluorescent lamp for illumination and the distance between the
MODULE and the eyes of the inspection shall be 35CM±5CM.

7) Determination of acceptability and subsequent disposal
If the number of defects found in the sample Module’s from the lot is equal to or less
than the applicable acceptance level, the lot shall be accepted.
If the number of defects is greater than the applicable acceptance level, the lot shall be
rejected. The Buyer shall inform the Seller of detailed result of such inspection within the
time period stipulated in Article 2.
The disposal is as follows:

a) Accepted lot

An acceptance under the above incoming inspection shall constitute an acceptance
by the Buyer of such lot of the Module’s in terms of the landed quality thereof.

b) Rejected lot

If a lot of PRODUCTS is rejected under the above incoming inspection due to any
defects for which the Seller is responsible and such a fact is clearly confirmed by
the Sellers, the Seller shall exercise one of the following three options. This must
be determined with mutual consent and shall be confirmed by the Seller. The best
choice of the options shall be left to the Seller’s discretion and the Seller shall
advise the Buyer of its choice not later than two weeks of receipt of the Buyer’s
advance:

(1) The Buyer shall return the defective lot to the place to be designated by the Seller

and Seller shall screen all of the PRODUCTS in the lot and repair defective
PRODUCTS.

(2) The Seller shall screen all of the PRODUCTS in the lot and repair defective products

within a reasonable time period at the Buyer’s facility.

(3) The Buyer shall screen the entire lot for the good modules at the expense of the

Seller to be separately agreed upon. The rejected PRODUCTS shall be returned to
the place to be designated buy the Seller.
