3.1. Panel PC Assembly
The LIBRA’s panel PC is composed of several modules
including a touchcreen module, LCD module, motherboard
module, I/O module and door module.
3.1.1. Touchscreen Module
The following steps illustrate the ways to integrate the
touchscreen module. Refer to Fig. 3-1.
1. Integrate the acrylic bezel (A) to the metal bezel (B)
with four bolts.
2. There are 4 one-side adhesive rubber strips. Attach the
4 rubbers to the front bezel (B). The 4 rubbers act as
bumpers to absorb the pressure when the touchscreen is
fixed to the front bezel.
3. There are 4 metal brackets (D) used to fix the
touchscreen to the front bezel. The metal brackets have
to be taped with foam sponge strips. The foam sponges
are used to absorb the pressure when the metal
brackets fix the touchscreen to the front bezel.
4. Fix the touchscreen (C) to the front bezel with the four
metal brackets and retain them together.
5. Make sure the touchscreen flat cable comes out from the
small opening of the touch bracket on the right side.
