5.1. Display Module Assembly
The display module consists of two modules, one front bezel module and the other LCD module.
5.1.1. Front Bezel Assembly
The following steps illustrate the ways to assemble touchcreen and some accessories to the front
bezel.
1. Refer to the figure below. There are four one-side adhesive foam sponges. Attach the four 1mm
sponge tapes to the front bezel (1). The sponge tapes act as bumpers to absorb the pressure when
the touchscreen is fixed to the front bezel.
2. There are 4 metal brackets (3) used to fix the touchscreen (2) to the front bezel. The metal
brackets have to be taped with foam sponges.
3. Put the touchscreen to the bezel with its active side facing downwards and its white flat cable at the
left side. Make sure the touch panel’s active area is aligned in the opening of the front bezel.
4. Make sure the white flat cable comes out from the underneath of the left bracket. Then, fix the
touchscreen to the front bezel with the four metal brackets and retain them together with three
PMS M3*6 screws for the up and down sides and two PMS M3*6 screws for the right and left sides.
The foam sponges are used bumpers to absorb the pressure caused by the four metal brackets
when driven tightly to the touchscreen.
5. Fix the IrDA/SPK board (4) to the front bezel with two PMS M3*5 screws.
6. The two speakers (5) are to be fixed to the right and left sides of the SPK board with two PMS 2*8
screws for each. The speaker wires are to be connected to the 2-pin CN1 and CN2 on the IrDA/SPK
board.
