LQ035Q7DH01 Datasheet, PDF (18/24 Pages) Sharp Electrionic Components – TFT-LCD Module

[Note 9-4] A measurement device is Minolta CM-2002.
[Note 9-5] Definition of reflection ratio
Reflection ratio =
Light detected level of the reflection by the LCD module
Light detected level of the reflection by the standard white board
[Note 9-6] A measurement device is ELDIM EZContrast
[Note 9-7] This is the reference value. The White-LED life time is defind as a time when brightness not to become
under 50% of the original value(at Ta=25 )

(11)Display quality
The display quality of the color TFT-LCD module shall be in compliance with
the Incoming Inspection Standards for TFT-LCD..
(12)Mechanical characteristics
12-1) External appearance
See Fig. 1
12-2) FPC (for LCD panel) characteristics
(1)Specific connector
FH12A-50S-0.5SH(HIROSE)
(2) Bending endurance of the bending slits portion
No line of the FPC is broken for the bending test (Bending radius=0.6mm and
angle=90°) in 30 cycles.
12-3) Design guidance for touchpanel(T/P)
12-3-1)Example of housing design
(1)If an consumer will put a palm on housing in normal usage, care should be taken as follows.
(2)Keep the gap, for example 0.3 to 0.7mm,between bezel edge and T/P surface.
The reason is to avoid the bezel edge from contacting T/P surface that may cause a “short”
with bottom layer(See Fig.2)
(3)Insertion a cushion material is recommended.
(4)The cushion material should be limited just on the busbar insulation paste area.
If it is over the transparent insulation paste area, a ”short” may be occurred.
(5)There is one where a resistance film is left in the T/P part of the end of the pole.
Design to keep insulation from the perimeter to prevent from mis-operation and so on.
