Predictions are fun, so, in 2030:
1) Panels per se will be gone. Instead you will paint the area you want on a wall with OLED-active paint and use a kind of projector to instruct each molecular mixel as to what wavelength and intensity to emit. Implants allowing full immersive VR that directly stimulates the optic nerve will be technically possible, but government policy will prevent mass-market, so that will be the differentiator for the uber-technorati who will be using their resources to get exemptions to the invasive government controls placed on the general populace. [One might even argue that the "war on distraction" will replace the "war on drugs" because of the need for increased GNP].
2) No speakers per se, instead ear tracking technology will allow synthesizing and projecting appropriate (multi dimensional) audio for each individual in the room, also allowing each to hear a different language dub. [Note that the technology to do this already exists at low TRL].
3) Dolby/DIRAC etc. will have reached the point where noise dampening to -80dB will be synthesizable for any room with relatively low cost (compared to current technology), allowing immersive experience for apartment dwellers near highways. [See #2
, essentially you just generate a counter-compression wave and project it. If you have enough sensors at the periphery you don't need to have them at the point of projection.]
4) No more discs, or even permanent licensing of content. Everything streamed using a rental/subscription model. [Already moving in this direction - subscription services up, disc purchases down.]
5) There will be the beginning of the equivalent of MIDI for creators, allowing schematic content to have various elements (like actor, style, setting) synthesized in real-time. This won't be available in the home in 2030, but will be by 2040. ("Siri, show me 'Terminator 2' set in 1854 Britain with Charlie Chaplain playing the terminator, and soundtrack by Vangelis.") [if you think this is a pipe dream, you haven't been paying attention to what's happening with deep fakes and computer based synthesis/imitation].
6) we will see the beginning of a merge between VR/AR and RR (real reality). Some will no longer be able to distinguish between them, leading to a whole new supplement to the DSM-VI.
