i want the holographic backbox mod
1) Can a full backbox LCD improve pinball?
Yes. And yes, you do play the playfield, but with excellent design, you can also play the LCD backbox. For example, folks who play Super Mario Bros Pinball & Theatre of Magic enjoy the mini-games on the DMD. It's a nice new dimension to the overall game play. The LCD should not just be about ripping clips from movies. For example, (as a tron LE owner) on Tron and on Transformers the movie clips are actually pretty tough to make out. Too busy & too monochromatic. Higher value use includes: LCD mini-games, making map choices to activate playfield mini-games/modes & changes to switches, status across many mini-games that can be in parallel completion, scores & other reward attributes (mana, health, armor, energy, d&d stuff) that have direct influence on the playfield states, inventory/items collected & choice to use to influence playfield &/or mini-games, quality display (not crappy/busy movie clips) of related brand scenes, vehicles, objects, weapons, characters, etc...
2) What does it take for full backbox LCD?
It needs a GPU (graphics processing unit), a CPU & ROM/RAM to manage the GPU, storage space for large art & video assets, & power. This will be a major change to the current hardware & Stern would need to hire talent (hint hint) to change both the hardware & software to support this.
3) Support
LCD's do have pixel problems. These defects are sometimes caused from: time of manufacturing, during shipping, during maintenance/movement of LCD, general use. A protective material is needed to place in front of the LCD (not unlike the Deal or No-deal machine) to reduce intentional damage when out in the wild. Support time, staff, equipment & overall costs WILL increase. Do a search for Dell/HP/IBM support related to monitors. It is painful. Stern would need to build those costs into unit prices. If I were Stern, I'd build a true investment model and full operating model to determine the total cost of ownership of this type of product change, then make the decision. (maybe they have).
i could be wrong...
