Notes:
(1) Display position is specific by the rise of DE signal only.
Horizontal display position is specified by the rising edge of 1st DCLK after the rise of 1st DE, is displayed on the
left edge of the screen.
(2)Vertical display position is specified by the rise of DE after a “Low” level period equivalent to eight times of
horizontal period. The 1st data corresponding to one horizontal line after the rise of 1st DE is displayed at the top
line of screen.
(3)If a period of DE “High” is less than 1920 DCLK or less than 1080 lines, the rest of the screen displays black.
(4)The display position does not fit to the screen if a period of DE “High” and the effective data period do not
synchronize with each other.
(5) Under 3D mode, signal should be input as following sequence: 1st line: right eye, 2nd line: left eye (when rotate
function is not implemented and Tcon position is at panel upper side).
The brightness of each primary color (red, green and blue) is based on the 8 bit gray scale data input for the color;
the higher the binary input, the brighter the color. The table below provides a reference for color versus data input.

Note:

approximately 45 minutes in a dark environment at 25°C. The values specified are at an approximate distance
50cm from the LCD surface at a viewing angle of φ and θ equal to 0°.

5. Light source here is the standard light source “C” which is defined by CIE and driving voltages are based on
suitable gamma voltages. The calculating method is as following:
A. Measure the “Module” and “BLU” optical spectrums (W, R, G, B) of AUO T550HVN01.5.
B. Calculate cell spectrum from “Module” and “BLU” spectrums.
C. Calculate color chromaticity by using cell spectrum and the spectrum of standard light source “C”.
6. Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are determined for the
horizontal or x axis and the vertical or y axis with respect to the z axis which is normal to the LCD surface. For
more information see FIG4.

backlight of Luminance
During transmittance measurement, the backlight of LCD module contains no brightness enhancement film.
Two diffuser sheets which diffuse the light source uniformly are suggested to use for transmittance
measurement.
8. 3D performance specification here defines 3D Crosstalk and 3D viewing angle. 3D crosstalk is measured at
panel center point under wearing glass condition.
a. Cross talk (middle) is defined by observation position which is 1.7m distance from panel center point and
human head in 0 degree steady vertical angle from panel mid axis level.
b. Cross talk (in vertical viewing angle) is defined by observation position which is 1.7m distance from panel
center point and observation range within specified degrees of vertical angle from panel mid axis level, and the
value is limited by 10%.
For more information, refer to 9-4 3D Measurement of 3D view angle.

8-3 Measurement of 3D Crosstalk
a. Test patterns KW, WK and KK are displayed, measuring distance is 1.7m.
b. Right or left eyeglass is placed in front of SR3 or equivalent equipment (as FIG1 showed) successively
and luminance is measured at panel center point where the notation for luminance measurement is
RL(W,W) and LL(W,W).
The angles are determined for the vertical or y axis with respect to the z axis which is normal to the LCD
module surface and measured at panel center position.
Please pay attention to the followings when you use this TFT LCD Open Cell unit and strongly recommended
to contact AUO if module process advice is required.
7-1 MOUNTING PRECAUTIONS
(1) You should consider the mounting structure so that uneven force (ex. Twisted stress) is not applied to the
cell. And the frame on which a cell is mounted should have sufficient strength so that external force is not
transmitted directly to the cell.
(2) Please attach the surface transparent protective plate to the surface in order to protect the polarizer.
Transparent protective plate should have sufficient strength in order to the resist external force.
(3) You should adopt radiation structure to satisfy the temperature specification.
(3) Acetic acid type and chlorine type materials for the cover case are not desirable because the former
generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break by
electro-chemical reaction.
(4) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB pencil
lead. And please do not rub with dust clothes with chemical treatment. Do not touch the surface of polarizer
for bare hand or greasy cloth. (Some cosmetics are detrimental to the polarizer.)
(5) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like
chamois soaks with petroleum benzene. Normal-hexane is recommended for cleaning the adhesives used
to attach front/ rear polarizers. Do not use acetone, toluene and alcohol because they cause chemical
damage to the polarizer.
(6) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes
deformations and color fading.
(7) Do not open the case because inside circuits do not have sufficient strength.
7-2 OPERATING PRECAUTIONS
(1) The open cell unit listed in the product specification sheets was designed and manufactured for TV
application
(2) The spike noise causes the mis-operation of circuits. It should be lower than following voltage:
V=±200mV(Over and under shoot voltage)
(3) Response time depends on the temperature. (In lower temperature, it becomes longer.)
(4) Brightness/transmittance depends on the temperature. (In lower temperature, it becomes lower.) And in
lower temperature, response time (required time that brightness is stable after turned on) becomes longer.
(5) Be careful for condensation at sudden temperature change. Condensation makes damage to polarizer
or electrical contacted parts. And after fading condensation, smear or spot will occur.
(6) When fixed patterns are displayed for a long time, remnant image is likely to occur.
(7) Module has high frequency circuits. Sufficient suppression to the electromagnetic interference shall be
done by system manufacturers. Grounding and shielding methods may be important to minimize the
interface.
(8)
7-3 ELECTROSTATIC DISCHARGE CONTROL
Since a open cell unit is composed of electronic circuits, it is not strong to electrostatic discharge. Make
certain that treatment persons are connected to ground through wrist band etc. And don’t touch interface pin
directly.
7-4 PRECAUTIONS FOR STRONG LIGHT EXPOSURE
Strong light exposure causes degradation of polarizer and color filter.
Rev.1.0
7-5 STORAGE
When storing open cell units as spares for a long time, the following precautions are necessary.
(1) Store them in a dark place. Do not expose the open cell unit to sunlight or fluorescent light. Keep the
temperature between 5 and 35 at normal humidity.
(2) The polarizer surface should not come in contact with any other object. It is recommended that they be
stored in the container in which they were shipped.
7-6 HANDLING PRECAUTIONS FOR PROTECTION FILM OF POLARIZER
The protection film of polarizer is still attached on the surface as you receive open cell units. When the
protection film is peeled off, static electricity is easily generated on the polarizer surface. This should be peeled off
slowly and carefully by people who are electrically grounded and with well ion-blown equipment or in such a
condition, etc.
