Continued from [3DS Teardown (4)] Prying Open Upper Chassis
The teardown of the Nintendo 3DS has finally entered its final stage. We started to disassemble the main targets: the two LCD panel modules.
We started with the 3D LCD panel module located in the upper chassis and carefully removed the LED backlight unit so that the LCD panels would not crack.
We found many optical components such as a light guide plate, reflecting plate and luminance enhancement film. There were as many as six components except for a frame, etc. Nintendo probably employed various measures to improve luminance because the module uses two panels: one for displaying images and the other for parallax barrier.
The two LCD panels were attached to each other with an adhesive film. The panel for displaying images was located on top of the panel for parallax barrier. The total thickness of the two panels including a polarizing plate was about 1.6mm. We gave up separating these two panels...
Then, we started to tear down the touch-sensitive LCD panel module located in the lower chassis. Its resistive touch panel and LCD panel module were separate parts. After removing the LED backlight unit, we found seven optical components.
We wrapped up the teardown, leaving the irreparable 3DS.
