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.
